Configuring identification using APPLID

CICS Transaction Gateway supports identification using APPLID. This provides a standard mechanism for identification of Gateway daemon and Java client components in the CICSplex, and for subsequent task correlation in CICS.

Gateway identification has implications for the following:

APPLID qualifier and APPLID

A fully-qualified APPLID is formed from an APPLID qualifier string and an APPLID string separated by a period symbol:
<APPLID qualifier>.<APPLID>
Each part can be between 1 and 8 characters in length and is defined independently. In certain configurations the defining of a fully-qualified APPLID is mandatory. See IPIC server connections for further details.

If the configuration file (ctg.ini) contains an APPLID but not an APPLID qualifier, the system uses the default value 9UNKNOWN for APPLID qualifier. For more information, see Gateway APPLID qualifier.

The APPLID parameter replaces the existing Client Application ID parameter. The Client Application ID parameter is supported for migration purposes, but is overridden by the new APPLID parameter.

Request monitoring data

The applid is available to the request monitoring exits and also transaction tracking across a CICSPlex. For more information, see Monitoring and statistics.
