About OpsCenter upgrade failure scenarios

In the versions prior to OpsCenter 7.6, the upgrade process first upgrades the OpsCenter software and then the database. If the upgrade fails, the database can become inconsistent and you cannot get it back to the original state.

Starting from OpsCenter 7.6, the database is upgraded in the beginning that is during the pre-installation process. In case of upgrade failure, the older OpsCenter setup is still available for use.

By default, the OpsCenter database is upgraded in the beginning. If you want the OpsCenter software to be upgraded first, you need to do the following:

To change the default upgrade sequence to upgrade database in the end

Make the following ENABLEPREDBUPGRADE registry entry on the OpsCenter Server host:

Windows	Create a registry value ENABLEPREDBUPGRADE=FALSE at the following location: `HKLM\\SOFTWARE\\Symantec\\OpsCenter\\Server`
UNIX	Before starting the upgrade, run the following command: EXPORT ENABLEPREDBUPGRADE=FALSE

Note:

In case of Windows silent installation, you need to add the following in the response file: <InstallProperty Name="ENABLEPREDBUPGRADE" Value="FALSE" />

See About editing the response file.

Table: Upgrade failure scenarios describes the possible upgrade failure scenarios and how you can recover the database in OpsCenter even though the upgrade has failed.

Table: Upgrade failure scenarios

Database upgrade	OpsCenter software upgrade	Required action
Successful	Failed	To use the upgraded database Remove the failed installation. Install OpsCenter as a fresh installation. Stop all OpsCenter services. Copy the upgraded OpsCenter database that was stored at the following location during the database upgrade to the new setup: On Windows - `OpsCenter_SavedData\OpsCenter\server\db\data\new_version` For example: `OpsDBBackup\OpsCenter\server\db\data\7.7` On UNIX - `OpsCenterServer_backup/new_version/SYMCOpsCenterServer/db/data` For example:`OpsDBBackup/7.7/SYMCOpsCenterServer/db/data` Start all services. To revert to the previous OpsCenter setup after the software upgrade failure Remove the failed installation. Install the previous base OpsCenter version and maintenance packs that were in place prior to upgrade. Stop all OpsCenter services. Copy the previous OpsCenter database that was saved at the following location during the database upgrade. On Windows - `OpsCenter_SavedData\OpsCenter\server\db\data` On Unix - `OpsCenterServer_backup/SYMCOpsCenterServer/db/data` Start all OpsCenter services.
Failed	Failed because the database upgrade was failed	Use the previous OpsCenter setup that is still intact. Check the database upgrade logs at the following location for errors to learn more about the root cause for the database upgrade failure: On Windows - `%ALLUSERSPROFILE%\Symantec\OpsCenter\INSTALLLOGS\pre-install-config\db\log` On UNIX - `/var/VRTS/install/logs/LogDirectory/db/log` LogDirectory is generated during the upgrade process.
