When you use unique UserIDs the Link3270 bridge facilities (and associated state data) are allocated and deleted as modeled in the Service Flow Modeler. The CICS® Service Flow Runtime server run-time makes no attempts to locate and cleanup Link3270 State file records left assigned upon successful or unsuccessful execution of request processes.
Since only the UserID is used and is assumed unique in this mode, any and all Link3270 bridge facilities (and associated state data) allocated for the specific UserID can be located and used in the execution of subsequent request processes by that UserID.
For example, as a normal end of day processing strategy, the service requestor could invoke a modeled flow as a process to locate and delete any allocated bridge facilities. Failure to incorporate a cleanup strategy for a specific user may not leave bridge facilities available in high volume environments over time to other users — unless the customer configuration is such that the bridge facility maximum keeptime, (BRIH-FACILITYKEEPTIME), is set such that bridge facilities are deleted in a timely fashion for that customer environment. For information on how to set the Link3270 bridge facility maximum keeptime, see information on the MAT_MAX_FAC_KEEPTIME property in the Service Flow Modeler help. For a definition of (BRIH-FACILITYKEEPTIME), see the CICS External Interfaces Guide Version 2 Release 2 .
