Bridge facilities are deleted after they have been unused for a given length of time. This is an optional parameter. This timeout value can be specified for use in a request to create a bridge facility for use in Link3270 server adapter(s). This parameter specifies the maximum timeout value in seconds. If this value is larger than the BRMAXKEEPTIME SIT parameter value in the AOR (router region), then CICS® will change this parameter in the link parameter list (but does not return the reduced value).
Use this parameter to ensure that CICS Service Flow Runtime and CICS do not run short of bridge facilities caused by adapter flows not de-allocating bridge facilities due to adapter processing errors. Setting this parameter ensures bridge facilities are not reserved for too long a period. Alternatively, do not specify this parameter too small causing bridge facilities to be deleted when not expected or desired. This could cause your CICS Service Flow Runtime flows to function incorrectly.
The default is BRIHKT-DEFAULT (value = 86400 seconds). See the CICS External Interfaces Guide Version 2 Release 2 for further information.
