Wave of the Future – Windows for Workgroups 3.11

Just because I was feeling nostalgic, I installed MS-DOS 6.22 with Windows for Workgroups 3.11 as a bonus! It really is amazing the amount of steps that used to be required to get a PC running and useful. Had to install CDROM drivers, Memory Management Software, TCPIP Stack, Network Drivers, and Display drivers. Linux and Windows really has come a far way in the last 15 years.

Restore OVM 3.x Manager with MySQL database

Mount OVM Manager CD
Run the runInstaller.sh -u {UID of OLD Manager}

Restoring the MySQL Database for Oracle VM Manager

To restore the database to one of the available backups, the manager and the database need to shutdown, for example as the root user execute the following commands:

# service ovmm stop; service ovmm_mysql stop
To initiate the restore, as the oracle user, use the RestoreDatabase.sh command located in the /u01/app/oracle/ovm-manager-3/ovm_shell/tools, for example:

# su – oracle
$ bash /u01/app/oracle/ovm-manager-3/ovm_shell/tools/RestoreDatabase.sh
AutoFullBackup-10222012_162543
INFO: Expanding the backup image…
INFO: Applying logs to the backup snapshot…
INFO: Restoring the backup…
INFO: Success – Done!
INFO: Log of operations performed is available at:
/u01/app/oracle/mysql/dbbackup/AutoFullBackup-10172012_122920/Restore.log

IMPORTANT:

As ‘root’, please start the OVM Manager database and application using:
service ovmm_mysql start; service ovmm start

The RestoreDatabase.sh script expects the name of the directory for a particular backup directory. You do not need to specify the full path to the backup directory as this is already specified in the DBBACKUP variable.

Once you have restored the database, restart the database and manager as the root user:

# service ovmm_mysql start; service ovmm start

IMPORTANT:

Make sure your time is correct! I spent 2 hours troubleshooting login issues to new environment and it was the TIME@@!@!!!!!
