Lifetime of the bridge facility

When simple transactions are run in single transaction mode , the bridge facility is created dynamically by CICS® and deleted at the end of the transaction.

In session mode , multiple transactions or pseudotransactions can be run using the same bridge facility. In this mode, the client application can request creation and deletion of the bridge facility, and can also specify a keeptime in BRIH-FACILITYKEEPTIME in the Allocate function. See Using Link3270 session mode.

The maximum keeptime value can be limited by the BRMAXKEEPTIME system initialization parameter. Bridge facilities are deleted automatically if they are inactive for the keeptime interval.

For information about system initialization parameters, see Specifying CICS system initialization parameters.
