SET CRYPTO
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
- 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.
- 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.
- Use the QUERY CRYPTO POLLING command to determine the current setting. See QUERY CRYPTO.
- 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.
- If a POLLING setting is not specified on a CRYPTO APVIRTUAL statement in the system configuration file, then the default setting is OFF.
