indefinitely until the former command terminates. To prevent the system from attempting to execute
such a command, you need to edit the Application Agent configuration definition file (

init.conf

),

which is stored in the following location:

Application-Agent-installation-directory

\DRM\conf\init.conf

init.conf

file format

COM_RETRY_TIME=number-of-retry-attempts

COM_RETRY_WAIT=duration-between-retry-attempts

The following values can be specified:
• Number of retry attempts: 0 to 3,600, with 0 representing indefinite retries. If you want to

stop indefinite retries, specify a value other than 0.

• Duration between retry attempts: 0 to 3,600 between each retry attempt (in ten-second inter-

vals).

In a cluster configuration of the Active-Active type, commands that cannot be executed concurrently
on a system might be executed at the same time if failover occurs due to system failure. If commands
that cannot execute concurrently are executed, the second command is retried indefinitely until the
first command finishes. If you want to stop the indefinite retry, edit the Application Agent configuration
definition file (

init.conf)

.

Executing multiple drmmediabackup or drmmediarestore commands concurrently

If you want to execute multiple

drmmediabackup

commands or

drmmediarestore

commands

concurrently, in the backup server specify the retry count and retry period for the command. For
details, see “

Stopping retry operations caused by a command that cannot execute concurrently with

other commands

” on page 240.

When the

drmmediabackup

or

drmmediarestore

command is executed, processing that cannot

execute the same command more than once at the same time is performed before and after the tape
backup management software starts. If you attempt to execute the same command during this
processing, the system retries execution of the activated command until the tape backup management
software starts. Therefore, when you want to execute multiple

drmmediabackup

commands or

drmmediarestore

commands at the same time, specify a sufficient retry period. If the retry period

is not sufficient, retries of the activated command may exceed the retry period, and an error will occur.

To specify the retry period, apply the following formula.

Specify a period longer than the following: (the period from the time the

drmmediabackup

command

or the

drmmediarestore

command is executed to the time the tape backup management software

starts)

x (

the number of commands executed concurrently)

If you attempt to execute multiple extended commands (

EX_DRM_TAPE_BACKUP

or

EX_DRM_TAPE_RESTORE

), more than one instance of the same command cannot run concurrently

during the period from the time the

drmmount

command is executed by the extended command to

the time the tape backup management software is started by the

drmmediabackup

or the

drmmediarestore

command. Therefore, when you want to execute multiple extended commands

(

EX_DRM_TAPE_BACKUP

or

EX_DRM_TAPE_RESTORE

), specify a sufficient retry period. If the retry

period is not sufficient, retries of the activated command may exceed the retry period, and an error
will occur.

To specify a retry period, apply the following formula:
