Making requests
Service request ID (reqID)
A service is uniquely defined in a request by its request ID (reqID).
The reqID is the service select code (ssc) and, if necessary, a parameter, as follows:
REQ=ssc,parameter
Duplicate requests are not allowed. Multiple requests for the same service can be active concurrently if the reqID for each request has a unique parameter. For example, all queued threads (REQ=THDQD) or the number of queued threads to TSO (REQ=THDQD,TSO) or to batch jobs (REQ=THDQD,BATCH) can be measured.
Tip: For faster searching, add an asterisk to the end of your partial query. Example: cert*
