Authorization

Privilege Class: B

Purpose

Use SET CRYPTO APVIRTUAL POLLING to specify whether CP uses polling or interruptions to drive the processing of crypto work that is assigned to the shared pool.

Operands

POLLing ON
CP uses polling to drive the processing of APVIRT crypto work.
POLLing OFF
CP uses crypto interruptions to drive the processing of APVIRT crypto work. CP does not use polling to drive the processing of APVIRT crypto work.

Usage Notes

  1. The command is allowed even if no shared pool is defined. The setting becomes active as soon as a shared resource is attached to the system.
  2. The command affects CP's processing of work for APVIRT crypto users. The command does not affect the way that a virtual machine places work in the shared pool or receives replies from crypto work that is processed by shared crypto resources.
  3. Use the QUERY CRYPTO POLLING command to determine the current setting. See QUERY CRYPTO.
  4. Use the CRYPTO APVIRTUAL POLLING statement in the system configuration file to specify the setting that takes effect at system IPL time. See CRYPTO APVIRTUAL Statement.
  5. If a POLLING setting is not specified on a CRYPTO APVIRTUAL statement in the system configuration file, then the default setting is OFF.
