Replication
Agent stores information about primary log devices in its RASD when
you initialize the Replication Agent instance. Log device information
in the RASD is referred to as the log device repository.
Unlike other information in the RASD, you can update the log device
repository at any time using the ra_updatedevices
command.
Note:
If any log device is added, dropped, extended, or moved at the
primary database, the Replication Agent log device repository must be updated.
If Oracle ASM is being used to manage redo logs and a disk is added to or
dropped from an ASM disk group, the device repository should be updated. Sybase
recommends that you coordinate all log device changes at the primary database
with updating the Replication Agent log device repository.
When you update the log device repository, Replication Agent:
If the path for a log device at the primary site is
different from the path for the corresponding log device at the standby site, you
must use ra_devicepath to specify the path to the
log device recorded in the RASD.
Note: The ra_devicepath
command is available only for Replication Agent for Microsoft SQL Server. The
primary database does not have to be quiesced when you update the Replication Agent
log device repository.
