Scheduling an SRB in an Independent Enclave z/OS MVS Programming: Workload Management Services SC34-2663-00 Scheduling an SRB in an Independent Enclave Suppose an address space representing a subsystem uses the specialized processing services of a supporting address space to satisfy a work request. The subsystem creates an independent enclave …
An enclave is a group of one or more logically related z/OS task control blocks (TCB) and service request blocks ( SRB ) that manage the work in entities. WLM enclaves To facilitate implementation of transaction management, WLM uses enclaves.
Enclave SRB Similar to an ordinary SRB but runs with enclave dispatching priority and is preemptible. IBM Software Group | Tivoli software … When a Stored Procedure is called from an application on z/OS DB2 creates an enclave for use by the Stored procedure Stored Procedure priority is the priority of the calling application address space …
The IWMEDREG macro allows you to deregister an enclave . The IEAMSCHD macro allows you to schedule an SRB into the enclave . For information about using the IEAMSCHD macro, see z/OS MVS Programming: Authorized Assembler Services Guide. The SYSEVENT ENCASSOC macro allows an enclave running SRBs to be associated with an address space. This way the …

For ManageNonEnclaveWork=NO and for Releases earlier than z/OS ® R12: It is assumed that no work consuming significant CPU service is running in the address space outside of an enclave . The CPU consumption of work running outside of enclaves is not included when Workload Management assesses the impact of CPU adjustments for the enclave work.
