You read the concept -

http://help.sap.com/saphelp_nw70ehp1/helpdata/en/27/44f17a26a74a8abfd202c4f5dc9a0f/content.htm

If you still face confusion then you may update the kernel in all the possible locations.

cleanipc is executed when sap is shut down before kernel upgrade.

Thanks

if your directory configuration is correct, it should be soft linked into sapmnt directory(may be not direct,if i am not mistaken it is linked to dbg first then to run). so the content should be all the same.

Hi,

message Coming Bash Command not found.

This might be because, you are trying to UNCAR kernel from ROOT user and Kernel path is not included in your users PATH environment.

Do this ...

1. Step in to the "/sapmnt/SID/exe" folder

2. execute "# mv SAPCAR SAPCAR1

3. execute "# ./SAPCAR -xvf <downloaded_kernel_folder>/SAPEXE_137-10005984.SAR"

4. execute "# sh saproot.sh <SID>"

5. execute "# sh oraroot.sh <SID>"

(In case of Oracle DB, or use the appropriate one...)

a little correction (no offence ^^), in step3 he means ./SAPCAR1

the alternative way execute the steps you already mentioned as <sid>adm user but it will give you error since you the package you extracted will produce another SAPCAR file which cannot replace current SAPCAR because it is already in used(for extracting). rename the SAPCAR file to avoid it.

Just my curiosity, are you skipping the database dependent exe update?

Hi,

Check the note 1636252 - Installing a 7.20 kernel in SAP Web AS 7.00/7.01/7.10/7.11

In short, copy *.CAR files under /usr/sap/<SID>/SYS/exe/run and extract the in it. After you restart the SAP, kernel will be copied by using "sapcpe" mechanism
