Entry points

DFHWSMNA

Called by

DFHXRA, MVS after attach of new TCB

Description

The CAVM state-management request router and subtask entry point is the initial entry point for a CAVM task attached by DFHWSSN1 to process the CAVM SIGNON command. It calls DFHWSSN2 to continue the processing of the SIGNON request and, if it is accepted, calls DFHWDINA to attach the tick generator module DFHWSTI as the first and highest-priority CAVM process. It is called under the CICS TCB to queue the CAVM TAKEOVER command for processing by the CAVM task, and to initiate processing of the CAVM SIGNOFF command by detaching the CAVM task. DFHWSRTR is the initial entry point for MVS subtasks attached by the CAVM task to perform various functions, such as issuing requests for CSVC services, or formatting new CAVM data sets when they are used for the first time.
