COMMAND ID TO'string'

Enters the specified string into the V$SESSION.CLIENT_INFO column of all channels. Use this information to determine which Oracle server sessions correspond to which RMAN channels. The SET COMMAND ID command applies only to channels that are already allocated. The V$SESSION.CLIENT_INFO column contains information for each RMAN server session. The data appears in one of the following formats: id=string id=string, ch=channel_id The first form appears in the RMAN target database connection. The second form appears in all allocated channels. When the current job is complete, the V$SESSION.CLIENT_INFO column will be cleared.
