In earlier posts we have seen how to patch infiniband switch and Cell Server.
Well, now let's continue with Database Server patching which is pending since long time.
Patching on Database server can be performed serially or in parallel using DCLI utility.
dbnodeupdate.sh utility is used to perform the database server patching
What dbnodeupdate.sh utility does?
- Stop/unlock/disable CRS for host restart
- Perform LVM snapshot backup of / filesystem
- Mount yum ISO image and configure yum
- Apply OS updates via yum
- Relink all Oracle homes for RDS protocol
- Lock GI home and enable CRS upon host restart
