You cannot change the circumstances, the seasons, or the wind, but you can change yourself. That is something you have charge of.


Moving to SaaS

Storing variables for later queries

Tom Kyte - 11 hours 39 min ago
Dear TOM This code is not working for me since my PL/SQL release is too old <code> -- Since PL/SQL 20.2.0.175 DEFINE usr = 'YourName'; SELECT * FROM Table1 WHERE CreatedBy = '&usr'; SELECT * FROM Table2 WHERE CreatedBy = '&usr'; </code> How can I run these two queries in my version? I have the following but will only work with one query not multiple queries. <code> WITH MyTab AS (SELECT 'YourName' as usr FROM DUAL) SELECT * FROM Table1 T1 INNER JOIN mytab M ON T1.CreatedBy = M.usr; </code> Thanks, Oren

Do you know Rancher Desktop?

Yann Neuhaus - Tue, 2022-01-25 08:38

Today I stumbled across Rancher Desktop and thought I’ll give it a try. If blogged about Rancher in the past but all those blogs talked about the full blown Rancher project. Rancher Desktop brings you “Kubernetes and container management on the desktop”, so the target audience for that are the desktops of developers. Lets try how easy it really is to bring it up own my own desktop, which is running openSUSE Tumbleweed.

For Linux, there is one zip file to download:

dwe@ltdwe:~/Downloads$ wget https://github.com/rancher-sandbox/rancher-desktop/releases/download/v1.0.0-beta.1/rancher-desktop-1.0.0-beta.1-linux.zip

Before you go further, please make sure that you have QEMU installed, as this is a requirement. Because I am already running virtual machines on my desktop there is nothing to do for me. For your reference, these are the packages installed on my system:

The installation of Rancher Desktop is really easy. All you have to do it this:

dwe@ltdwe:~/Downloads$ ls -l rancher-desktop-1.0.0-beta.1-linux.zip
-rw-r--r-- 1 dwe users 354886544 Jan 25 13:44 rancher-desktop-1.0.0-beta.1-linux.zip
dwe@ltdwe:~/Downloads$ mkdir rd
dwe@ltdwe:~/Downloads$ cd rd/
dwe@ltdwe:~/Downloads/rd$ unzip ../rancher-desktop-1.0.0-beta.1-linux.zip && ./rancher-desktop

This will bring up the first dialog asking for the version of Kubernetes you want to use:

I’ll go with the default version. As soon as you selected what you want, the download of Kubernetes is starting:

You should also see a new icon in your system tray where you can switch the Kubernetes context:

In the settings you can adjust CPU and memory usage:

If you take a look at the processes on your desktop you’ll notice that a virtual machine was started up:

dwe@ltdwe:~/Downloads/rd$ ps -ef | grep -i qemu | grep rancher
dwe       8622  8607 17 14:45 pts/1    00:05:33 /home/dwe/Downloads/rd/resources/resources/linux/lima/bin/qemu-system-x86_64 -cpu host -machine q35,accel=kvm -smp 2,sockets=1,cores=2,threads=1 -m 4096 -boot order=d,splash-time=0,menu=on -drive file=/home/dwe/.local/share/rancher-desktop/lima/0/basedisk,media=cdrom,readonly=on -drive file=/home/dwe/.local/share/rancher-desktop/lima/0/diffdisk,if=virtio -cdrom /home/dwe/.local/share/rancher-desktop/lima/0/cidata.iso -netdev user,id=net0,net=192.168.5.0/24,dhcpstart=192.168.5.15,hostfwd=tcp:127.0.0.1:44787-:22 -device virtio-net-pci,netdev=net0,mac=52:55:55:a5:73:8b -device virtio-rng-pci -display none -device virtio-vga -device virtio-keyboard-pci -device virtio-mouse-pci -parallel none -chardev socket,id=char-serial,path=/home/dwe/.local/share/rancher-desktop/lima/0/serial.sock,server=on,wait=off,logfile=/home/dwe/.local/share/rancher-desktop/lima/0/serial.log -serial chardev:char-serial -chardev socket,id=char-qmp,path=/home/dwe/.local/share/rancher-desktop/lima/0/qmp.sock,server=on,wait=off -qmp chardev:char-qmp -name lima-0 -pidfile /home/dwe/.local/share/rancher-desktop/lima/0/qemu.pid

The usual utilities like kubectl and helm are automatically linked into your home directory:

… and you can use them right away:

dwe@ltdwe:~/Downloads/rd$ kubectl get ns
NAME              STATUS   AGE
default           Active   43m
kube-system       Active   43m
kube-public       Active   43m
kube-node-lease   Active   43m

To get rid of Rancher Desktop, simply delete all the files on disk after you stopped the GUI:

dwe@ltdwe:~/Downloads/rd$ rm -rf /home/dwe/.config/rancher-desktop
dwe@ltdwe:~/Downloads/rd$ rm -rf /home/dwe/.local/share/rancher-desktop
dwe@ltdwe:~/Downloads/rd$ rm -rf /home/dwe/.cache/rancher-desktop
dwe@ltdwe:~/Downloads/rd$ rm -rf /home/dwe/Downloads/rd

Nice project.

Los Angeles car accident: Check more about California’s fault system  

OraQA - Tue, 2022-01-25 06:35

An astounding number of auto accidents are reported in and around Los Angeles every year. Unfortunately, not everyone gets compensation from the negligent party. California is an at-fault state, which means if the other driver was reckless, driving under the influence of substance, or negligent in general, they are liable for your losses. The compensation lets you manage the financial distress caused as a direct result of the accident. If you wish to maximize the final settlement, you may want to hire one of the top car accident attorneys Los Angeles. In this post, we are sharing more on California’s fault system and how an attorney can help. 

What is California’s fault system?

California is a “pure” comparative fault state. The fault system in the state allows you to recover a settlement from the other driver, even when you are more at fault. Of course, your fault share will determine what you get from the settlement given to you. How does the fault system work in real life? Let’s say you were given $1,00,000 in a settlement for your car accident claim but were also found to be 40% at fault. You can now recover only $60,000 as the final settlement. If your fault share was 60%, you could still recover $40,000 as a settlement. Keep in mind that the other party may also sue you in such circumstances. 

How to deal with a car accident?

First and foremost, do not leave the scene and call the local police. Wait for an investigating officer to arrive and ensure that you share your version of the case. Do not engage in altercations with the other driver, and make sure that you don’t admit fault. You can exchange contact and insurance details with other drivers. Call 911 if someone is injured. Even if your injuries don’t seem that severe, check with an injury doctor soon after the accident. 

Why do you need a lawyer?

Insurance companies are unlikely to play fair with claimants. Even if you do all the needful and file a car accident claim, the other party’s insurer will do what it takes to deny or delay your claim. Also, there is a deadline of two years set by the statute of limitations in California, and therefore, you don’t have much time to spare either. Hiring an attorney can increase your chances of getting a fair settlement, especially if your losses are significantly huge. 

Call a lawyer soon after your LA car accident.

Catalog Catalogue

Jonathan Lewis - Tue, 2022-01-25 06:22

This is a good starting point to researching a topic on my blog. It’s simply list of the various catalog(ue)s of articles that I’ve written over the years. There’s still a lot of work to do, though, as there are more than 1,500 articles on the blog:

 

 

255 column catalogue

Jonathan Lewis - Tue, 2022-01-25 06:17

This is a short list of articles discussing the problems (almost always) and oddities that appear when you define a table with more than 255 “real” columns. Odd details are always subject to change over time/version – so if it matters, test it and check it.

database vs instances

Tom Kyte - Tue, 2022-01-25 05:46
Tom, I am little confused about Oracle Database and instances. If I have created a database DB1, and started it,open for all users, does it mean it is one instance? How can I have multiple instances of a database and how do I find what Instance I am using? So, Can I have two instances of same database or when I say two instances, it's two different databases ? Sorry, I am not a DBA and got confused while reading about instances. Can oyu please explain me a little bit about instances [very basics] Hope your answer can clarify my confusion :-) Thanks,

New indexes and updating stats for long-running queries

Tom Kyte - Tue, 2022-01-25 05:46
Hi, 1) There is batch program executing and one query running long is accessing a table T. It is found that an index on column will help query and batch can't be killed. Can we create an index on column of a table which is being used by long running query 2) Can we gather statistics on that table online and will that take effect ? Thanks, Girish

What does decoupling of index and table access mean in an execution plan?

Tom Kyte - Tue, 2022-01-25 05:46
Hi. My question is about "execution plan". I have a query as you can see below : <code>select t2.n1, t1.n2 from t2,t1 where t2.n2 = 45 and t2.n1 = t1.n1 ;</code> There?s an index to support the join from t2 to t1 and I've Used "dbms_xplan.display_cursor" to get the real execution plan for this query . what I've got is this plan : <code>------------------------------------------------------------------------------------------------- | Id | Operation | Name | Starts | E-Rows | A-Rows | A-Time | Buffers | ------------------------------------------------------------------------------------------------- | 0 | SELECT STATEMENT | | 1 | | 225 |00:00:00.01 | 3048 | | 1 | NESTED LOOPS | | 1 | 225 | 225 |00:00:00.01 | 3048 | | 2 | NESTED LOOPS | | 1 | 225 | 225 |00:00:00.01 | 3038 | |* 3 | TABLE ACCESS BY INDEX ROWID| T2 | 1 | 15 | 15 |00:00:00.01 | 3013 | | 4 | INDEX FULL SCAN | T2_I1 | 1 | 3000 | 3000 |00:00:00.01 | 13 | |* 5 | INDEX RANGE SCAN | T1_I1 | 15 | 15 | 225 |00:00:00.01 | 25 | | 6 | TABLE ACCESS BY INDEX ROWID | T1 | 225 | 15 | 225 |00:00:00.01 | 10 | ------------------------------------------------------------------------------------------------- Predicate Information (identified by operation id): --------------------------------------------------- 3 - filter("T2"."N2"=45) 5 - access("T2"."N1"="T1"."N1")</code> My question is that despite having only one join in the query , why do we see two "Nested Loops" in the plan ? I've searched about this and the only thing I found was that it is called "decoupling of index access and table access" , but I couldn't find any detail information regarding this . I was wondering if you could explain a little bit more about that. Thanks in advance

Remembering the bad old days of shared hardware…

Tim Hall - Tue, 2022-01-25 05:07

I’m in the middle of a conversation with my boss about some old shared kit and it reminded me of the bad old days of shared hardware. Nowadays we try to keep things really simple, with each VM/container serving a single purpose. Containers are great for this, because they allow the ultimate in granularity without … Continue reading "Remembering the bad old days of shared hardware…"

Grand Junction car crash: Answering top frequently asked questions

OraQA - Tue, 2022-01-25 04:24

Like anyone else, you may have many questions in your mind after suffering injuries in a car crash in Grand Junction. Although unfortunate, auto accidents are reported regularly on the roads of Colorado. Many victims do not get the settlement they deserve, often because they didn’t know how or from where to seek compensation. Regardless of other factors, you should consider hiring a Grand Junction personal injury lawyer for your case. Attorneys are skilled negotiators and can fetch you a fair settlement, depending on the circumstances. In this post, check the answers to commonly asked questions about auto accidents in Colorado. 

Do you need to report the accident?

Yes. Colorado laws require drivers to report auto accidents when injury, death, or significant property damage is involved. In general, it is advisable to call the local law enforcement from the accident scene. Also, wait for a law enforcement officer to arrive. 

Is it mandatory to hire an attorney for auto accident claims?

The short answer is no. If the other driver was at fault, you could file a third-party claim, for which you don’t need a lawyer. However, hiring a personal injury lawyer is always beneficial. As we mentioned, lawyers can negotiate better, and more importantly, if you need to file a civil lawsuit, their expertise will come in handy. 

“What if I was partly at fault?”

Let the attorney know if you believe that you had a share in the fault. Colorado follows the modified comparative fault rule, where you can only sue the other driver if they were more at fault. However, your fault percentage will determine what you get from the given settlement. Let’s say you were given $10,000 as your final settlement but were found to have a 10% share in the fault. You will eventually get $9,000 as compensation because of the modified comparative fault rule. 

“Can I file an accident lawsuit when I want?”

Typically, you will file a third-party insurance claim, and it is always wise to do so at the earliest. If the insurance offer is unacceptable or your case is worth more, you can file a lawsuit. The statute of limitations in Colorado allows three years to file car accident lawsuits, and the clock starts running from the accident date.

There is no denying that car accident lawsuits and claims can be tricky. This is one of the key reasons why you should seek legal representation.

Oracle Partition and Performance of massive/concurrent Inserts

Yann Neuhaus - Mon, 2022-01-24 16:11

For a customer, I had to check if partitioning improves performance of massive and concurrent inserts.

The goal is to execute several Inserts in parallel via dbms_parallel_execute package (my previous blog “parallelize your Oracle Insert with DBMS_PARALLEL_EXECUTE” explains how to use dbms_parallel_execute).

The idea is to insert more than 20 millions of rows in 2 tables :

  • One table not partitioned –> DBI_FK_NOPART
  • One table partitioned in HASH –> DBI_FK_PART

Both table have the same columns, same indexes but of different type :

  • All Indexes on the table partitioned are global:
    • CREATE INDEX …GLOBAL PARTITION BY HASH (….)….
  • All indexes on the table not partitioned are normal
    • CREATE INDEX …ON…

Now let’s inserting about 20 millions of rows in each tables via the procedures we created above:

SQL> set timing on
SQL> set autotrace on
SQL> begin
  2  test_insert_nopart;
  3  end;
  4  /

PL/SQL procedure successfully completed.

  2  test_insert_part;
  3  end;
  4
  5  /

PL/SQL procedure successfully completed.

Elapsed: 00:00:22.92


SQL> select max(pkey) from xxxx.dbi_fk_nopart;

 MAX(PKEY)
----------
9980650809

SQL> select 9980650809 - 9960649804 from dual;

9980650809-9960649804

9980811483-9950649803
---------------------
             30161680


FIRST CONCLUSION:

  • About 20 millions of rows has been inserted into the table not partitioned “DBI_FK_NOPART”  in 06.30.34 mins
  • About 30 millions of rows has been inserted into the table partitioned “DBI_FK_PART”  in 22 sec

Do a massive concurrent INSERT on a huge table is always faster on table partitioned compare a table non partitioned.

 

Now, let’s check OEM graphics to understand why the Insert is 17 times faster into DBI_FK_PART than DBI_FK_NOPART

Between 03:40 PM and 03:46 PM, we can see the peak related to the Insert on DBI_FK_NOPART

At 03:49 PM, we can see a very small peak related to the Insert related to DBI_FK_PART

 

 

If we focus only on the INSERT command (1st line and 4th line), the one into DBI_FK_PART (table partitioned) waits less on CPU (green) and CONCURRENCY (purple) compare to INSERT in DBI_FK_NOPART (Table partitioned) where the I/O is the event the most important.

Let’s see more in details on which event the database is waiting for both INSERT:

For INSERT into DBI_FK_NOPART:

And if we click into Concurrency Event :

For INSERT into DBI_FK_PART:

If we click on Concurrency Event :

 

SECOND CONCLUSION

The event “db file sequential read” seems indicate that the difference of response time between the both tables seems due to the type of index we created on each table (Global Partitioned Index on partitioned table VS Normal Index on nonpartitioned table).

As it’s possible to create Global Partitioned Index on nonpartitioned table, another “interesting” test (not done on this blog) should be to replace normal indexes by global indexes on non partitioned tables and check if response time is faster.

To conclude, if we have Partitioning license, in term of performance, we should always partition huge tables accessed several times in read (SELECT) or in write (INSERT).

Mistakes To Avoid When Choosing A Guardian For A Minor

OraQA - Mon, 2022-01-24 13:49

Nobody wants to think about dying while they still have minor children. However, death is inevitable, and it can happen when you least expect it. Along with estate planning, it is essential to choose a guardian for your children and establish their guardianship before it is too late. 

If you do not establish guardianship before you pass away, the decision of who gets to raise your children is then rested with the courts. 

Nobody knows your children better than you, and only you know what is best for them. Therefore, seek a San Antonio guardianship lawyer and complete the guardianship process as soon as possible. However, remember to avoid a few costly mistakes while you are at it. 

Mistakes to avoid when choosing a guardian for a minor 

  • Not thinking long-term. 

The person you choose as the guardian of your children should be a medically fit person who is likely to be around for a long time. However, the person is still human, and it is always a wise choice to have a backup plan. Make sure to choose another guardian to take over if the first one passes away before your children are capable of providing for themselves. 

  • Not telling the people you pick as guardians. 

When choosing a guardian, you should not keep it a surprise from that person. While some may be thrilled and emotionally touched that you chose to trust them with your children, most people are not. You must first consult whether they are comfortable with bearing the responsibility for raising another person’s child and then only initiate the process of guardianship. 

  • Not providing instructions on how you want your children to be raised.

As they are your children, you must want them to have the same core values and beliefs as you. It is not easy to find someone who can oversee your child exactly like you, but a person can come close with the help of a few instructions. Issues about their religion, school, nutrition, etc., should be addressed to make sure they are raised the way you want them to. 

  • Not specifying the names of people you do not want around your child. 

Most people are initially confused about choosing a guardian, but they certainly know who is not fit for the role. You must clarify that you do not want certain people to raise your children. Even if extended family members disagree with your decision, they would not be able to do much about it. 

Choosing a guardian can be an emotionally challenging process. After all, the chosen person would be replacing you as a parent, which is a pretty big deal. For help regarding the legal process and documents, contact an attorney today.

Clone Oracle 21c Home

Yann Neuhaus - Mon, 2022-01-24 09:56

When deploying new Oracle Home on the same server or on a new server, you may use the downloaded Oracle binaries and do an install from scratch as usual. You may then apply any patch you have on your actually Oracle Homes. This may take time.
Oracle provides tools to clone an existing Oracle Home with all patches on top on it. I usually use the famous clone.pl script, but does it still work with Oracle 21c?
I decide to do some tests on my small lab

I actually have this following Oracle Home with the patch 33239276

oracle@oraadserver:/home/oracle/ [DB21 (CDB$ROOT)] echo $ORACLE_HOME/
/u01/app/oracle/product/21.3.0/db_1/

oracle@oraadserver:/u01/app/oracle/product/21.3.0/ [DB21 (CDB$ROOT)] opatch lspatches
33239276;Database Release Update : 21.4.0.0.211019 (33239276)

OPatch succeeded.
oracle@oraadserver:/u01/app/oracle/product/21.3.0/ [DB21 (CDB$ROOT)]

I decide to clone it in the same server using the traditional clone.pl script

1- Copy the binairies in db_1 in the new db_2 Oracle Home. Feel free to proceed as you like (zip, cp, tar…). Just adjust the permissions as they are on db_1

[root@oraadserver 21.3.0]# pwd
/u01/app/oracle/product/21.3.0
[root@oraadserver 21.3.0]#

[root@oraadserver 21.3.0]# ls -ld *
drwxr-xr-x. 66 oracle oinstall 4096 Dec 20 14:52 db_1
drwxr-xr-x. 66 oracle oinstall 4096 Dec 20 14:52 db_2
[root@oraadserver 21.3.0]#

2- Run the script clone.pl as follow with user oracle

oracle@oraadserver:/home/oracle/ [DB21 (CDB$ROOT)] /u01/app/oracle/product/21.3.0/db_2/perl/bin/perl /u01/app/oracle/product/21.3.0/db_2/clone/bin/clone.pl ORACLE_BASE="/u01/app/oracle" ORACLE_HOME="/u01/app/oracle/product/21.3.0/db_2"  ORACLE_HOME_NAME=OraDB21Home3

INFO: This host is not an Exadata system.


[INFO] [INS-32183] Use of clone.pl is deprecated in this release. Clone operation is equivalent to performing a Software Only installation from the image.
You must use /u01/app/oracle/product/21.3.0/db_2/runInstaller script available to perform the Software Only install. For more details on image based installation, refer to help documentation.

..................................................   100% Done.
oracle@oraadserver:/home/oracle/ [DB21 (CDB$ROOT)]

Despite the fact that we have the warning “[INFO] [INS-32183] Use of clone.pl is deprecated in this release…”, the process was successful. We now just have to run the root.sh script as required

[root@oraadserver 21.3.0]# /u01/app/oracle/product/21.3.0/db_2/root.sh
Check /u01/app/oracle/product/21.3.0/db_2/install/root_oraadserver_2022-01-24_13-07-38-506111736.log for the output of root script
[root@oraadserver 21.3.0]#

And we can then verify that the Oracle Home clone was fine.

oracle@oraadserver:/home/oracle/ [rdbms213c2] echo $ORACLE_HOME/
/u01/app/oracle/product/21.3.0/db_2/
oracle@oraadserver:/home/oracle/ [rdbms213c2] opatch lspatches
33239276;Database Release Update : 21.4.0.0.211019 (33239276)

OPatch succeeded.
oracle@oraadserver:/home/oracle/ [rdbms213c2]

But as we can see the clone.pl is deprecated, Oracle recommends performing a Software Only installation from the image. How this process does work?
Let’s see this method

1- Let’s create the gold image using the runInstaller command as below

From the source Oracle Home

[oracle@oraadserver ~]$  /u01/app/oracle/product/21.3.0/db_1/runInstaller -createGoldImage -destinationLocation /home/oracle/gold_software/
Launching Oracle Database Setup Wizard...

The wizard should run following images

If you do not have a graphical environment configured or do not want to use the graphical tool, just use the silent option in the command

[oracle@oraadserver ~]$  /u01/app/oracle/product/21.3.0/db_1/runInstaller -silent -createGoldImage -destinationLocation /home/oracle/gold_software/

2- Let’s now use the goldimage to deploy a new Oracle Home

The first step is to unpack the goldimage on the new Oracle Home folder

oracle@oraadserver:/home/oracle/gold_software/ [rdbms213c] ls -ltra
total 3622644
drwx------. 8 oracle oinstall       4096 Jan 24 13:38 ..
-rw-r--r--. 1 oracle oinstall 3709576334 Jan 24 13:44 db_home_2022-01-24_01-38-44PM.zip
drwxr-xr-x. 2 oracle oinstall         46 Jan 24 13:44 .
oracle@oraadserver:/home/oracle/gold_software/ [rdbms213c] mkdir -p /u01/app/oracle/product/21.3.0/db_2
oracle@oraadserver:/home/oracle/gold_software/ [rdbms213c] unzip -d /u01/app/oracle/product/21.3.0/db_2 db_home_2022-01-24_01-38-44PM.zip

And after we can start the deployment with the runInstaller in the new Oracle Home

[oracle@oraadserver db_2]$ pwd
/u01/app/oracle/product/21.3.0/db_2
[oracle@oraadserver db_2]$ ./runInstaller

The install process is the same that usual ( But here we will not need to install the eventual patches as they are already in the GoldImage). I will not show all screenshots for the install

And at the end of the installation, we can verify that the new Oracle Home has the same patch level

oracle@oraadserver:/home/oracle/ [rdbms213c2] opatch lspatches
33239276;Database Release Update : 21.4.0.0.211019 (33239276)

OPatch succeeded.
oracle@oraadserver:/home/oracle/ [rdbms213c2]

Note that here also you can use a silent install if you do not have or do not want graphical tool

We can also validate that the Oracle Inventory is fine

oracle@oraadserver:/home/oracle/ [rdbms213c2] opatch util LoadXML -xmlInput /u01/app/oraInventory/ContentsXML/inventory.xml
Oracle Interim Patch Installer version 12.2.0.1.27

   from           : /u01/app/oracle/product/21.3.0/db_2/oraInst.loc

UtilSession: XML file is OK.

OPatch succeeded.
oracle@oraadserver:/home/oracle/ [rdbms213c2]
Conclusion

We saw how to clone an existing Oracle Home to a new one. Although you can still use the traditional clone.pl script it is highly recommended to adopt the gold image method for the latest Oracle versions

Examine some important point before you get sofa repair

OraQA - Mon, 2022-01-24 04:25

When you’re searching for the right piece of furniture for your home, it can be time consuming, from initially visiting a store, exploring your options then having it delivered, the whole process can take up to at least a week if you’re lucky. However, if you want to save yourself a trip to multiple furniture stores, the repair process could not be easier and more convenient.

Today in this modern era where glamour of the product attracts people toward itself and they do not understand the worth of valuable things purchase long before.  The quality of those old products is far more than the trendy ones today. While others are having certain furnishings that individuals are notably keen on. Over time we have it within our homes and kind a selected quite relationship with the furniture. Whether or not it’s the first sofa repairsd you brought, or family piece passed all the way down to you from your grandparents. Where you’ve got your piece of furniture from once it starts getting old many of us met with a hardcore decision: It can be time to think about one thing new. So, want to have sofa repair service, you need to know about some important points before you get to work.

Sofas are the basic asset, need for every home. They should be comfortable and relaxing so for this comfort you need to have sofa repair by experts. Along with the size, shape and material in repairing, should ask to repair sofa spring. This is the basic thing to be replaced first. This could reflect the change, giving good comfortable feeling and also restore the furniture to new.

Choose well-known company to have cost effective sofa repair

To decide restoration rather than buying new can leave you with an increase of money into your pockets. This may provide you with the benefit of having the ability to create a different style at home. Moreover, Its quality is just not as good as what you already own. So, one of the best reasons for this would be, it’s cheaper and worth it. Repairing your sofas by well-known companies means that you can get back your quality set of sofas for a much cheaper cost.

New style however Same piece of furniture

Whether or not your furniture is getting old it is not the reason it can’t previous you for a long time to come. Having properly restored or fixed can make furniture look fresh. Whether you want to provide your old furniture a complete makeover to fit your evolving preferences.  Or you just want to restore original glory to help improve the vintage feel of your house, furniture restoration will probably be your answer. Sofa repair can provide it just the appearance you want. Will you want to have it changed with something you will find more appealing? Your older furniture mended and restored can provide it a full face-lift while still conserving the aspects that made you fall deeply in love with it.

Repairing sofa is more Eco-Friendly

Though you might not seem to enjoy it, by rebuilding your existing furniture rather than buying new, you are in fact assisting in doing your part in guarding the surroundings. Scientific data demonstrates rebuilding and refinishing your existing furniture can significantly lessen your carbon footprint.

Always go for best selection in quality and material

Always go with such companies who provides you the one with finest quality of materials and provides their customers with great decorative ideas and solution. As we know sofas are not made in the same way it was years ago which is quite unfortunate.

All You Need to Know About Spine Surgery

OraQA - Sun, 2022-01-23 12:10

The spine is the main supporting structure in our body, consisting of individual bones called vertebrae. The spine helps us to maintain an upright posture and enables us to move around with ease. Different types of spinal conditions require surgery like degenerative disc disease, spondylolisthesis, scoliosis, etc.

Pain is the primary symptom of any spinal condition. There may also be other symptoms like numbness or tingling, loss of power or control over lower limbs, bowel and bladder problems, etc. Sometimes an injury to the spine can cause these conditions too. In some cases, you may need to see a Dayton spine surgery specialist for treatment.

Who Needs Spine Surgery?

Surgery is required for a spine condition when the pain and other symptoms are not better with medicines. Surgery may also be needed if there is compression on any nerve due to a damaged disc or bone spur in the neck or lower back. Some of the most common conditions that require spine surgery include :

  • Degenerative disc disease. It is the most common spinal condition and affects mainly older people. It occurs when the discs are worn out between the vertebrae (bones) that make up the spine. As the discs wear out, it results in loss of height or compression of the spine, resulting in pain and numbness or weakness in the arms.
  • Spondylolisthesis. In this condition, forward slippage of one vertebra over another can pinch a nerve resulting in back pain, etc.
  • Scoliosis. When the spine curves to the left or right side, it results in a condition called scoliosis. If the angles are mild, they can be treated with medicines and exercises, but severe cases require surgery to correct the asymmetry.
  • Spinal tumors. These mainly develop in the later years of life and may cause numbness or weakness, back pain, etc. Surgery is usually required to remove such tumors for relieving pain.
  • Spinal deformities. These are conditions that cause an abnormal shape or curvature of the spine requiring surgery for correction.
What Are the Common Types of Spine Surgery?

The common types of spine surgery include :

  • Laminectomy. It is a procedure that involves the removal of the back wall (lamina) of one or more vertebrae to relieve pressure on the spinal cord or nerve roots.
  • Discectomy. In this surgery, the damaged disc is removed to relieve pain and other symptoms. 
  • Kyphoplasty/vertebroplasty. This is a procedure to reduce pain in vertebral compression fractures or collapsed vertebrae caused by osteoporosis. The surgeon implants a balloon device into the compressed vertebra during this procedure under X-ray guidance before inflating it to restore the normal height.
  • Laminoplasty. It is a procedure that involves the removal of part or all of the lamina in the back wall of one or more vertebrae to relieve pressure on the spinal cord or nerve roots for conditions like scoliosis, kyphosis, etc.

In summary, spine surgery can help correct some conditions affecting the spine. Common spine conditions that require surgery include degenerative disc disease, scoliosis, spinal tumors, and spinal deformities. Most procedures conducted by spine surgeons include laminoplasty, kyphoplasty, discectomy, and laminectomy.

  • Sleep Apnea Remedy

The specialists will make the proper diagnosis for you as you seek the correct treatment for your particular case. They are highly committed to helping you get rid of sleep apnea problems through surgeries or any other remedy that may prove necessary to enhance your appearance and wellbeing.

The best way to treat sleep apnea is to do breathing exercises or to use a CPAP machine. You also need to ensure that you are getting enough sleep and not using your tongue for sleeping. They guide you on the connection between your airway and snoring sleep.

  • Acid Reflux Remedy

Different foods and drinks can cause acid reflux and heartburn. Sometimes spicy foods and alcohol make things worse. Once you know what is causing the problem, decide whether or not you want to avoid it. If you decide you want to prevent it, then take steps to lessen the effect of the food on your stomach such as eating slower and chewing more. 

Lying down for a while after eating also helps with acid reflux, without entirely avoiding it. The professionals can guide you on the daily practices that can help remove the problem. Some examples of some of these practices include avoiding fatty foods and avoiding dozing off after mealtimes.
