ibmtech, thank you for the reply. I like the alternative disk suggestion. I'll look into that
Sorry, my steps are a bit sparse. I'll give a bit more detail for my item of 'Apply SP9 update'.
mksysb is the backout plan
I always do the following before applying the update:
If any of these checks reveal something amiss, it is corrected before proceeding:-
- Check available space for the mksysb and update processing
- check exclude.rootvg
- generate the mksysb - smitty mksysb
- verify the mksysb - lsmksysb -f
- oslevel -s
- instfix -i|grep ML
- installp -C
- lppchk -v
- installp -s
- installp -c all if some packages are not committed
- emgr -P to determine if there are any efixes which may cause a conflict
- If a DB server, ps -ef|grep smon and agent to verify the DBs are down
- I run the update from a NIM - smitty nim, using the preview only option
- If all looks good, then I proceed with the actual update, access the system, redo all the pre checks to confirm current status, shutdown -Fr, redo all the checks again to ensure it all came up healthy
I do have the DBA team verify the oracle version is compatible with the intended OS update. I also read up to determine myself.
I'm curious if applying the SP while the databases are still up would cause issues. The oracle is 11G, on AIX 7 TL1 SP9. I'd try it in a test area, if I could.
