Hi Gustavo,

1. Download the latest SAP kernel from Service Market Place and place into a temporary directory i.e. save *.sar files in to temp directory. ( Refer to SAP Note: 19466 )

2. Uncar *.sar files using sapcar utility i.e. sapcar u2013xvf *.sar to the temp directory.

3. Stop SAP and SAP related services.

4. Take a backup of the old kernel ( if there are any issues you can revert back the old kernel again )

Go to <Installation Drive>/usr/sap/<SID>/SYS/exe

Take a backup of the run folder.

5. Now copy the files in the run directory which you have uncarred in the temp directory to <Installation Drive>/usr/sap/<SID>/SYS/exe/run ( it will ask for a replace of files Click Yes )

6. Start SAP.

7. Check the Kernel Patch Level.

Deepanshu,

Do you realise that this is the Windows forum and that the Original poster told us that he uses Windows 2003 ?

Answering with Unix shell commands is kind of strange !

Gustavo,

Kernel:-The kernel is the central component of the database system. The kernel manages access to the permanently stored data in a database instance and processes the SQL statements; for liveCache database instances, it processes the OMS procedures.

To start a database instance, the kernel of the database system is started for the specific database name. While the database is running, the kernel includes several different operating system threads.

The database system is delivered with several different kernel variants.

The kernel is platform dependent.In kernel upgrade there are two set of files one is DB independent (DW,ENQ, ENS, SAPOSCOL etc ) & another one is DB specific both are platform dependent.

Read below thread to check how to upgrade kernel patches.

You can upgrade your kernel patch level by using JSPM as well. See below link for details
