KERNEL UPDATE

#Kernel Update 3 Files

1.    SAPEXE.SAR

2.    SAPEXEDB.SAR

3.    DBATOOLS.SAR

There is an extractor to extract the .SAR files. Extractor name = SAPCAR.exe

Directory Path:  c:\usr\sap\dev\sys\exe\uc\ntamd64

# KERNEL UPDATE PROCEDURE   SAP OS LEVEL UPDATE

     

      1.      SAPEXE.SAR

      2.      SAPEXEDB.SAR

      3.      DBATOOLS.SAR

We will download these files from www.services.sap.com   kernel update i.e. from 710 to 720.

There is an extractor to extract the .sar files. SAPCAR.EXE

After downloading these .sar files go to Run Win+R = Run then type SERVICES.MSC

Then find two services –

1 SAPDEV_00 (Here DEV is SID & 00 is instance no)  

2 SAPOSCOL / SAPDAA (SAPDIAG AGENT)  [SAPOSCOL is now replaced with host agent SAPDAA]

STOP BOTH THE SERVICES BEFORE UPDATING THE KERNEL.

Now in C:\ directory where SAP is installed in server navigate to directory.

i.e.  c:\usr\sap\dev\sys\exe\uc\NTAMD64

Just cut all the files from this folder and paste it in a new folder named as kernel old.

Now make a new folder on desktop named as KERNELNEW & paste the 3 .sar files and the SAPCAR.exe extractor too.

Then open CMD command line – cd desktop – cd kernel new – cd sapcar.exe –xvf  “filename of the .sar file which you want to extract using tab”

Now extract all three files using the extractor & after that paste these files in the same directory i.e. c:\usr\sap\dev\sys\exe\uc\NTAMD64 
&  c:\usr\sap\<sid>\DVEBMGS00\exe

After replacing the files open services.msc using run (win key+r)

Then start the services previously stopped

1 SAPDEV_00 (Here DEV is SID & 00 is instance no)  

2 SAPOSCOL / SAPDAA (SAPDIAG AGENT)  [SAPOSCOL is now replaced with host agent SAPDAA]

START BOTH THE SERVICES AFTER UPDATING THE KERNEL.
