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:
