a 'real' procedure for NetWever ABAP stack only KERNEL UPGRADE

51 Views

Does SAP make available some where a real procedure

for NetWever 7.0 ABAP stack only KERNEL UPGRADE ?

a lot of people have questions ? answer are even available... but still... even experienced

basis admin having trouble now with Kerne Upgrade

Main line :

stopsap, clean shared memory

stopsap

saposcol -k

ps -ef|grep sapstartsrv

kill <sapstartsrv_pids>

cleanipc <inst_nr>

lsnrctl stop

backup your kernel

cd /sapmnt/<SID>

cp -pr exe exe.001

extract new kernel

cd exe

SAPCAR -xvf <YOUR_DW.SAR>

or

. 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/  840413 /sapmnt/SID/exe

du -sk /SIDkernel_10102007  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

AND STILL ... FOLLOWING ALL THE STEPS... I have the work process going down

as soon as i put back old kernel is working fine again

I'm trying to upgrade to :

SAPEXE_179-20000978.SAR

SAPEXEDB_179-20000979.SAR

DBATL700O10_39-20000979.SAR

on an AIX 64 bit with Oracle 10G

Error I'm getting is :

FAIL: NIECONN_REFUSED (Connection refused), NiRawConnect failed in plugin_fopen()

and even the dpmon cannot work

dpmon pf=/usr/sap/H1D/SYS/profile/H1D_DVEBMGS00_dehrdb01

DpMonInit failed - possibly no dispatcher running

So, my QUESTION is : DOES SAP have a detailled procedure to do the Kernel Upgrade on NW7.0

for an ABAP stack only installation ?
