EBS Upgrade Part 1 - 11.5.9 Database 9i RHEL 4 to EBS 12.2 Database 19c OEL 7
The first step towards getting this insance up was to build a RHEL 4. Hmm this was a challenge to bring up a OS with RHEL 4 in 2020. So had a old laptop and got the OS up and running then did the below task to get the EBS 11.5.9 Up and Running
- Validate and Untar DB and MT binaries
- perl adcfgclone.pl dbTechStack
- Manually Recover the Database , SID Change to EBSDB
- perl adcfgclone.pl dbconfig
- Database Validation
- Update MT Stage Context File with Fix for IAS/8.0.6 Home
- Update DB SID/Hostname in the Stage Context File
- Fix instconf.drv and remove em entries and files
- perl adcfgclone.pl appsTier
- Post Cloning Start Fails - apply patch and relink all
- Restart Services and Health Check
After restore figured out that the database is 9.2.0.3 and still needs a one layer up level to 9.2.0.4. In the next part I will be upgrading it.
Refer to the Index Page to see the full flow of the upgrade.
