Using SMF 87 records

SMF 87 record subtype 1 helps you identify global generic queue scan issuers. SMF 87 record subtype 2 helps you diagnose application problems related to ENQ and DEQ and monitor the usage of ENQ/DEQ/ISGENQ/RESERVE requests.

SMF 87 records are mapped by macro SYS1.SAMPLIB(ISGYSMFR). In order to access a record programmatically, use macro IFASMFR.
