This command is available only for Oracle.
Changes the raw disk device read offset for a log device recorded in the RASD.
ra_deviceoffset device_id, device_offset
The device ID is the Oracle redo log “Group number.”
The offset of the raw device from which Replication Agent starts a log scan.
Example 1
ra_deviceoffset 1,20
This command specifies the raw device read offset to the log device ID “1” as:
20
When ra_devicepath is invoked, Replication Agent records the specified raw device read offset for the specified log device in the RASD.
To get information about log devices stored in the RASD, use the ra_helpdevice command.
When ra_updatedevices is invoked, device offset is not reset to the default value. The default device read offset is zero.
If ra_deviceoffset is invoked when the Replication Agent instance is in Replicating state, it returns an error.
The ra_deviceoffset command is valid only when the Replication Agent instance is in Admin state.
