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.
