Hi,

If your O/S is unix

1. Login as root

2. Make new backup directory

cd /

mkdir SIDkernel_10102007

3. Create latest kernel backup

cp -pr /sapmnt/SID/exe/* /SIDkernel_10102007

4. Compare the original kernel and the backup

du -sk /sapmnt/SID/exe/ à 840413 /sapmnt/SID/exe

du -sk /SIDkernel_10102007 à 841992 /SIDkernel_10102007

5. Make new shadow kernel directory

cd /

mkdir newkernel_175

6. Copy the new downloaded kernel files into /newkernel_175

7. Unpack the new downloaded kernel in folder /newkernel_175

SAPCAR -xvf SAPEXE_175-20000221.SAR

SAPCAR -xvf SAPEXEDB_175-20000223.SAR

8. Login as sidadm

9. Stop the SAP System

stopsap

10. Stop saposcol

saposcol -k

11. Login as root

12. Go to the current kernel directory

cd /sapmnt/SID/exe

13. Copy all extracted support packages into this folder

cp -pr /newkernel_175/* /sapmnt/SID/exe

14. Copy back the original file saproot.sh into this folder.

cp -p /SIDkernel_10102007/saproot.sh /sapmnt/SID/exe

15. Go to the current kernel directory

cd /sapmnt/SID/exe

Then run:

./saproot.sh SID

16. Login as sidadm

17. Start the saposcol service

saposcol

18. Start the SAP system

startsap

Also pls check this SAP NOTE 19466

Hi ,

These two are only files to upgrade yor kernel.However please make a practice to take backup of old kernel before upgrading it.

You need to uncar these kernel & replace it with new one after stopping your SAP system & SAPOSCOL with other SAP service.

Thanks..
