Apache,

Please identify the following:

1) Is this a CI installation?

2) Is this a Unicode system?

3) Are there application servers involved? Are the application servers running the same OS as the CI?

4) What is your promotion strategy here - where are you starting?

The kernel update is relatively simple, but it does require some planning before hand. Let's get these questions answered in order to build a proper strategy first, then worry about execution.

Cheers,

Hi apache,

This question has been asked and answered many, many times on SDN before. There are also instructions in SAP Notes.

Also, please check your spelling and capitalization before posting.

Hi,

Follow below process.

1. Download the .CAR files from SAPNet .

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

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

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

Download below files

SAPEXE---.SAR -DATABADE INDEPENDENT

SAPEXEDB---.SAR -for your specific database

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

6. Stop SAP.

7. Stop SAPOSCOL

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.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.
