Changes the raw disk device read offset for a log device recorded in the RASD.
This command is available only for Oracle and Microsoft
SQL Server.
ra_deviceoffset device_id, device_offset
For Oracle, the device ID is the Oracle redo log “Group number.” For Microsoft SQL Server, this device ID can be obtained using the ra_helpdevice command.
The offset of the raw device from which Replication Agent starts a log scan.
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 the Admin, Replicating, or Replication Down state.
