Customizing the Data Protector Environment

Using Omnirc Options

•OB2DEVSLEEP: Changes the sleep time between each retry while loading a device.

•OB2ENCODE: Allows a user to always turn on data encoding, regardless how the backup options are set in the backup specification.

•OB2OEXECOFF: Allows a user to restrict or disable any object pre- and post-execscripts defined in backup specifications for a specific client.

•OB2INCRDIFFTIME and OB2CHECKCHANGETIME:

The OB2INCRDIFFTIME variable specifies a time period (in minutes) imposed after checking the inode change time for incremental backups. The latter one is specified by the OB2CHECKCHANGETIME variable.

It means that the referential time, the time of the previous backup, received from the Session Manager is incremented by the specified period and the OB2CHECKCHANGETIME value is checked against incremented time to qualify for backup.

OB2INCRDIFFTIME is specified in minutes and works only together with OB2CHECKCHANGETIME.

•OB2RECONNECT_ACK: Defines how long Data Protector should wait for the message of acknowledgment (default 1200 seconds). In other words, if the agent does not get an acknowledgment in OB2RECONNECT_ACK seconds, it will assume that the socket connection is no longer valid.

•OB2RECONNECT_RETRY: Defines how long Data Protector should wait before trying to reconnect after a socket connection has been broken (the default is 600 seconds). In other words, the WAN line between the Backup Session Manager and agents cannot be down more than OB2RECONNECT_RETRY seconds.

•OB2REXECOFF: Allows a user to disable any remote session pre- and post-execscripts for a specific client.

•OB2SHMEM_IPCGLOBAL: This option should be set to 1 on HP-UX clients that have both the Disk Agent and the Media Agent installed, in case the following error occurs during the backup:

Cannot allocate/attach shared memory (IPC Cannot Allocate Shared Memory Segment)

System error: [13] Permission denied) => aborting
