restore 11g homes

Below is a script to restore Oracle RDBMS Home , Oracle grid home and other /etc config files on a host from a previous backup.

When do we need to use the script?

After the HDD of a database host (part of RAC) goes bad and if it had to be replaced and reimaged with new OS, once the OS is installed and eth is set by the SA team,

following script can be used to restore the oracle software from a previous backup.

How to run the 11g binary restore script:

1) Make sure a previous good and clean backup of the same host exists already under /net/dba/backup/<HOST_NAME>

2) SA to complete the reimage and set up eth interconnect and hand over to the DBA’s.

3) Login as root to the newly reimaged host and copy /etc/fstab from other host of the RAC and mount /net/dba

4) Run /net/dba/panama/scripts/backup/restore_11g_homes.sh as root

5) Run /home/oragrid/product/11.2/root.sh as root

6) Startup the instance and relocate services.
