    Migrate OVMM to a different server

    官方手冊:Administrator's Guide for Release 3.3 第五章 Backing up and Restoring Oracle VM Components

    For whatever reason you ever need to migrate an OVM Manager to a different host this would be helpful. I can’t imagine that this would need to happen that often but I recently did need to cut it over from a Virtualbox instance to an OVM Hypervisor. This is the OVM 3.2.1 local mysql(not Oracle XE) DB version.

    Find the source UUID:

    # more /u01/app/oracle/ovm-manager-3/.config
    DBTYPE=MySQL
    DBHOST=localhost
    SID=ovs
    LSNR=49500
    OVSSCHEMA=ovs
    APEX=8080
    WLSADMIN=weblogic
    OVSADMIN=admin
    COREPORT=54321
    UUID=0004fb0000010000434a8179cda0edbd
    BUILDID=3.2.1.516

    Copy recent backup and stage on new host. You can make a manual mysql backup or I just used the latest Auto backup:

    # tar cpf a.tar AutoFullBackup-20130501_201957
    # scp a.tar [email protected]:/root
    

    Some pre-requisites the install would be pointing out:

    # grep oracle /etc/group
    dba:x:501:oracle
     
    # tail -3 /etc/security/limits.conf
    * soft nofile 16384
    * hard nofile 65536
    # End of file
     
    [[email protected] a]# ulimit -aH
    ...
    open files                      (-n) 65536
    ...
    

    Install Manager on new host using old UUID:

    # pwd
    /mnt/a
     
    # ./runInstaller.sh --uuid 0004fb0000010000434a8179cda0edbd
