Using transaction routing to control resource use

To protect high-speed transactions in your system from potential long-running QMF queries that might consume extra resources, consider isolating execution of QMF transactions to a single region, using multiregion operations or intersystem communications. Define one CICS terminal-owning region and route QMF transaction requests to other regions by using multiple transaction IDs or dynamic routing exits. Both methods are described in the CICS/OS390 Intercommunication Guide.

See Program parameters for OS/390 and z/OS for information on how QMF uses temporary storage in the CICS region on OS/390 or how QMF uses GETVIS storage in the CICS partition on VSE.
