Hi Amit,

Folloe below process.

1. Download the .CAR files from SAPNet .

2. Log on to www.service.sap.com/swcenter .

3. On the screen click on download support packages & patches.

4. Download all the files from Database Independent & Oracle node and upload the same to the server where the patches have to be applied.

5. Log on to the server and take a backup of existing Run directory.

6. Stop SAPR/3 and Database.

7. Stop the following services:

SAPOSCOL & SAP<SID>, Oracle service, Oracle Listener Service.

8. Go to Usr\sap\sid\sys\exe\run through Command prompt and UNCAR the above .CAR Files with the command car u2013xvf< path where the .CAR files are located> < .CAR file name> replacing the old Executables..

9.Restart the Server.

10.Start Database & SAP.

11.Check for Transactions SM21, SAPDBA check (OS Level) and DB13, ST22, ST11 (dev_ms, dev_disp) .

Kernel Upgrade Procedure with Unix as Operating system.

Check whether the Unix is 32 bit or 64 bit operating system and download the relevant kernel from the Service Marketplace.

Download the Database depenedent and Database independent packages.

Or Order a CD containing patches from Service Market Place.

A) Prior to importing the new R/3 kernel from the CD/Downloaded files proceed as follows:

1. When you upgrade to the new kernel, problem with the statistics collector might occur. Therefore, you need to delete the stat file. To prevent data loss, start the statistics collector manually (Transaction SE38, report RSSTAT83). In Transaction ST03 or ST03N, check that the statistics are updated for all active instances in the system.

2. Stop the SAP System (stopping the database is not required).

3. Stop saposcol.

$cd /usr/sap/<SAPSID>/SYS/exe/run

./saposcol -k

$rm saposcol

B) Extract the new R/3 kernel (Binary patches) from CD/Download from Service Marketplace:

1. Branch to directory /sapmnt/<SAPSID>/exe.

2. Back up the old R/3 kernel with the following commands:

$mkdir oldkernel

$cp -p * oldkernel

$su - root

$chown <sapsid>adm /sapmnt/<SAPSID>/exe/*

$exit

The directory oldkernel will be deleted during the next regular upgrade.

C) Unpack CAR/SAR files in a folder and Copy them to following directory /usr/sap/<SAPSID>/SYS/exe/run.

Logon as user <sapsid>adm and execute the following commands:

$su - root

$cd /sapmnt/<SAPSID>/exe

$ sapcar u2013xvf *.CAR

$exit

D) Restart the System in following order

1. Start saposcol

cd /usr/sap/<SAPSID>/SYS/exe/run

./saposcol u2013l

2. Start Database

3.Start the SAP System.

Dear Amit,

Please follow the below steps for Kernel Upgrade:

1. Take the backup of exe folder /sapmnt/SID/exe

2. Uncar the both kernel patches DB dependent and DB independent in one folder.

3. Stop the SAP System and oracle and also the services(1. Distibution transaction coordinator,2. oracle related 3. SAP system related)

4. Then copy all uncared files to exe folder, then check disp +work file to confirm whthere kernel upgraded or not.

5. Then start services first and database and SAP.

Hope it resolves your doubt.

Thanks
