/opt/omni/lbin/utilns/detach pre_script [arguments...]

• You can disable a session’s

pre-

and

post-exec command

execution

on the Cell Manager by setting the

SmDisableScript

global option to

1.

• You can disable remote session

pre-

and

post-exec

command

execution on any client by adding

OB2REXECOFF

=1 into the

omnirc

file

on the specific client.

• You can secure the client by specifying which Cell Managers are

allowed to access the client. Only permitted Cell Managers will be
able to execute

pre-

and

post-exec

commands on the client. For

more information on securing a client, refer to the HP OpenView
Storage Data Protector Installation and Licensing Guide
.

Pre- and Post-Exec Commands for a Specific Backup Object

Pre-

and

post-exec

commands for an object are executed before and

after the backup of the object, respectively. You can specify these
commands for all objects in a backup specification, or for each individual
object. When backing up integrations, for example Oracle, the database
is considered as an object, so the commands are executed before and after
the database backup. These commands are executed on the system
where the Disk Agent is running.

Where to Locate
the Commands

Pre-

and

post-exec

commands for backup objects on UNIX systems are

started by the backup session owner, unless the backup session owner
has the

Back up as root

permission and the commands are then

started under root.

On UNIX Cell Managers and clients, the

exec

commands for backup

objects can reside in any directory, and the full pathname must be
specified when defining the backup specification. However, for host
backups the

exec

commands must reside in the

/opt/omni/lbin

directory on HP-UX or in

/usr/omni/bin

on other UNIX systems. In this

case, only the filename can be specified. The commands have to be
located on the system where the Disk Agent is running.

How to Specify the
Filename or
Pathname

For information on how to specify the commands, refer to the online Help
index keyword “pre- and post-exec commands for backup objects”.
