Enclave

Enclaves are a z/OS resource used when a task will need more than one DU in its processing.

WLM will perform any prioritization that it would normally do for an address space for the enclave.

Although any authorized program can be set up to run in an enclave, most will continue to run in a single address space.

Some of the uses of enclaves include DB2, WebSphere Application server and IBM MQ.
