Usage notes

For optimal performance, ensure that you have enabled CPACF in the thread doing the processing, by making a quick call on the host side at thread startup time, to Cryptographic Resource Allocate, specifying the correct HCPUACLR and HCPUAPRT keyword values for your operation. See the Cryptographic Resource Allocate rule_array keyword definitions, and see Access control points that affect CPACF protected key operations for more affected verbs. Note that it is the user's responsibility to ensure that all adapters accessible to the operating system use the DEV-ANY state. Further use of DEV-ANY as a target adapter for verbs that modify the state of an adapter (such as the generation of retained keys) can lead to unexpected results. See Multi-coprocessor selection capabilities for more information.
