EBS Upgrade Part 1 - 11.5.9 Database 9i RHEL 4 to EBS 12.2 Database 19c OEL 7

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.

EBS Upgrade 11.5.9 Database 9i RHEL 4 to EBS 12.2 Database 19c OEL 7

It is December and learning time. Was doing a cleanup of old drive and found a TAR Backup of Vision 11.5.9 with Database 9.2.0.3 which I took it 15 years back. I remember the Operating System was RHEL 4.

So this is what I am going to do ....

Going to take this instance to EBS 12.2 Database 19c OEL 8

This page is going to be the Index Page and I will update all the links for the rest of the journey here. I hope this will help someone.
