Step 1: Copy the Oracle VM Manager configuration file

[root@mgmtsrv ~]# ssh root@ovm.lab.local
root@ovm.lab.local's password:
Last login: Sun Dec 17 02:59:42 2017 from 10.10.10.1

[root@ovm ~]# mkdir /opt/OVM_Backup


[root@ovm ~]# cp /u01/app/oracle/ovm-manager-3/.config /opt/OVM_Backup/

Step 2: Backup MySQL database repository

[root@ovm ~]# /u01/app/oracle/ovm-manager-3/ovm_tools/bin/BackupDatabase -w
Enter your OVM Manager username: admin
Enter your OVM Manager password: ## Enter VM Manager admin password ##

INFO: Backup job starting with destination:
/u01/app/oracle/mysql/dbbackup/ManualBackup-20171217_053626

Job Id = 'Start Backup to: ManualBackup(1513506985746) Uri: https://localhost:7002/ovm/core/wsapi/rest/Job/1513506985746'
Job Name = 'Start Backup to: ManualBackup'

INFO: Backup job finished

[root@ovm ~]# cp -r /u01/app/oracle/mysql/dbbackup/ManualBackup-20171217_053626 /opt/OVM_Backup/

Don’t forget to take backup of Oracle VM Manager UUID is persisted in the /etc/sysconfig/ovmm file

[root@ovm ~]# cp /etc/sysconfig/ovmm /opt/OVM_Backup/

Please make sure that you have taken above necessary backup before upgrade/reinstall or migrate the Oracle VM Manager.

[root@ovm ~]# ls -a /opt/OVM_Backup/
. .. .config ManualBackup-20171217_053626 ovmm

Step 3: Uninstall the Oracle VM Manager

Make sure you have MySQL repository backup before you start the uninstallation.

[root@ovm mnt]# ls -l /u01/app/oracle/mysql/dbbackup/
drwxr-xr-x 5 oracle dba 4096 Dec 12 04:52 ManualBackup-20171217_053626

Stop VM manager related services

[root@ovm mnt]# /etc/init.d/ovmcli stop
Stopping Oracle VM Manager CLI [ OK ]
[root@ovm mnt]# /etc/init.d/ovmm_mysql stop
Shutting down OVMM MySQL.... SUCCESS!
[root@ovm mnt]# /etc/init.d/ovmm stop
Stopping Oracle VM Manager [ OK ]

Uninstall the VM Manager

[root@ovm mnt]# ./runInstaller.sh -n

Oracle VM Manager Release 3.3.3 Installer

Oracle VM Manager Installer log file:
/var/log/ovmm/ovm-manager-3-install-2017-12-14-024725.log

Uninstall completed ...

Step 4: Re-Install the Oracle VM Manager

Note down the old VM Manager UUID value

[root@ovm ~]# cat /etc/sysconfig/ovmm
RUN_OVMM=YES
USETLS1=YES
DBBACKUP_CMD=/opt/mysql/meb-3.12/bin/mysqlbackup
JVM_MAX_PERM=512m
JVM_MEMORY_MAX=4096m
DBBACKUP=/u01/app/oracle/mysql/dbbackup
UUID=0004fb000001000060c2c1d955c85575

Reuse the same usernames and password for the database schema, Oracle WebLogic Server and Oracle VM Manager administration user.

[root@ovm mnt]# ./runInstaller.sh -n --uuid 0004fb000001000060c2c1d955c85575

Oracle VM Manager Release 3.3.3 Installer

Oracle VM Manager Installer log file:
/var/log/ovmm/ovm-manager-3-install-2017-12-14-025058.log

Oracle VM Manager installation complete.

Step 5: Restore Oracle VM Manager from backup

Before restoring the backup, First we need to stop Oracle VM Manager related services.

[root@ovm ~]# /etc/init.d/ovmcli stop
Stopping Oracle VM Manager CLI [ OK ]
[root@ovm ~]# /etc/init.d/ovmm_mysql stop
Shutting down OVMM MySQL.... SUCCESS!
[root@ovm ~]# /etc/init.d/ovmm stop
Stopping Oracle VM Manager [ OK ]

Before restore the database, we need to make sure that no database files already exist on the Oracle VM Manager host.

[root@ovm ~]# cd /u01/app/oracle/mysql/data/
[root@ovm data]# rm -rf appfw ibdata1 ib_logfile0 ib_logfile1 mysql ovs performance_schema


[root@ovm data]# ls -a
. .. auto.cnf my.cnf .mysqlconfig mysqld.err

Switch to oracle user to start the restore process.

[root@ovm ~]# su - oracle
[oracle@ovm ~]$ bash /u01/app/oracle/ovm-manager-3/ovm_tools/bin/RestoreDatabase.sh ManualBackup-20171217_053626
INFO: Restore area already exist... Cleaning up...
INFO: Expanding the backup image...
INFO: Applying logs to the backup snapshot...
INFO: Restoring the backup...
INFO: Restoring OVM keystores and certificates
INFO: Success - Done!
INFO: Log of operations performed is available at: /u01/app/oracle/mysql/dbbackup/ManualBackup-20171217_053626/Restore.log

IMPORTANT:

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

[oracle@ovm ~]$ exit
logout

Start the Oracle VM Manager related services

[root@ovm ~]# /etc/init.d/ovmm_mysql start
Starting OVMM MySQL..... SUCCESS!
[root@ovm ~]# /etc/init.d/ovmm start
Starting Oracle VM Manager [ OK ]
[root@ovm ~]# /etc/init.d/ovmcli start
