EVM Jobs and Job Management
In the Windows Clone Example on page 9–2, the mount operation mounts partition 1
of each of the three BCVs as drives t:, u:, and v: on an EVM host agent named
“backupserver.”
Mount Volume Operation
After creating the BCVs and restoring the application on the EVM host agent
computer to the normal mode of operation, the mount volume operation mounts the
BCVs on an EVM host agent computer.
In the UNIX Clone Example on page 9–3, the mount operation mounts the copy of
logical volume lv00 as /mt/lv00-bcv on an EVM host agent named “backupserver.”
Launch Operation
Most jobs end with a launch operation that executes a user-specified command on the
desired EVM host agent. Typically, this is the same EVM host agent on which the
mount operations were performed. The most common use for this operation is to
invoke a backup application to copy the data from the mounted BCVs to tape.
In the Windows Clone Example on page 9–2, a batch file named backup_db.bat
executes on the backupserver host using the WAIT parameter.
In the UNIX Clone Example on page 9–3, a script named backup_db.sh executes on
the backupserver host using the WAIT parameter.
Windows Snapshot Unit Example
The following snapshot job example illustrates function sequences for a typical
Windows-based snapshot job:
SUSPEND WAIT dbserver “freeze.bat”
SNAP UNIT SUBSYS1 D1 $temp1
SNAP UNIT SUBSYS2 D1 $temp2
RESUME NOWAIT dbserver “thaw.bat”
MOUNT UNIT SUBSYS1 $temp1 backupserver 1 x:
MOUNT UNIT SUBSYS2 $temp2 backupserver 1 y:
LAUNCH WAIT backupserver “run-backup.bat”
Each operation is explained in the operation sections that follow.
UNIX Snapshot Volume Example
The following snapshot job example illustrates function sequences for a typical
UNIX-based snapshot job:
SUSPEND WAIT dbserver freeze.sh
SNAP VOLUME dbserver /mnt/lv00 $BCV1
