Kernel Upgrade

Postby akapu » Wed Jun 07, 2006 5:51 pm

1) I was looking at kernel upgrade sap note # 664679, where after unpacking the new kernel, it asks to run ./ <SAPSID>

However since year I have been doing kernel upgrades but never ran tht script. Can any one plz tell me what does it do as even though I never used it, every thing ran fine.

2) Also I would like to ask a basic stupid but annoying question. All the kernel files are under /usr/sap/<SAPSID>/SYS/exe/run. However each time I do a kernel upgrade I do it on /sapmnt/<SID>/exe.

This time just to experiment the thing I did it in correct path usr/sap/<SAPSID>/SYS/exe/run, however the kernel upgrade didnt took place. I mean once the SAP was up, it still shows 620 version wheras I downloaded and installed 640. When I did that again, on /sapmnt/<SID>/exe, the kernel version changed to 640.

Since I am new to Unix landscape, can any one of you please help me understand this sapmnt ?

Just to add I verified that the /sapmnt/<SID>/exe is not pointing to /usr/sap/<SAPSID>/SYS/exe/run.

1. changes the permissions of the br* tools

2. /sapmnt/SID/exe is a link to /usr/sap/SID/exe/run. In the installation guide of SAP on Unix, you can see an overview of the file system structure of an SAP system on Unix.

1. ... and some other tools, have a look at the script, you can read it with vi etc.

2. Have you done an 'slibclean'? Sometimes the old executables are still in the memory ....

akapu, you could have viewed the contents of the script and try to understand what it does.... :roll:
