Reports

Programs and JCL procedures can generate three reports from the collected data. Three procedures collect data for single MVS™ system input, and three procedures collect data for multiple MVS systems input to support sysplex. For multiple systems, input to the procedures is concatenated. These programs do not require authorization.

They are:

  • Procedure ISGAJE1 for sequential trace report with single MVS system input. Program used is ISGAMED1. The output generated is shown in Figure 1.

  • Procedure ISGAJE1A for sequential trace report with multiple MVS systems input. Programs used are ISGAMED2, ISGAMED3 and SORT. The output generated is shown in Figure 2.

    The reports contain the following information:

    • Date and time of the request.
    • SMF system id.
    • Jobname of the requester.
    • Program name of the requester.
    • Module authorization information (only for ISGAJE1).
    • SVC type.
    • RNL action.
    • Scope of the request.
    • Volume serial for reserve requests.
    • Major and minor name
    • Device number for reserve requests.
    • Minor name length.
  • Procedure ISGAJE2 for volume reserve time report with single MVS system input.

  • Procedure ISGAJE2A for volume reserve time report with multiple MVS systems input. The output generated is shown in Figure 3.

    Programs used are ISGAMEDM - ISGAMVOL - ISGAMCTM - ISGAMMRT and SORT.

    For every volume with reserve activity the following is given:
    • Count of reserve requests.
    • Time when the volume had the longest reserve.
    • Highest volume reserve count.
    • Average, minimum and maximum reserve time in msec, milliseconds, used for times up to 999.999 milliseconds.
    • Total reserve time in sec.
    • Reserve rate per minute.
    • The list of resources that reserved the volume with the timing information.

    The output is sorted by volume reserve time for ISGAJE2 and by SMF system id and volser for JCL652A.

  • Procedure ISGAJE3 for resource report with single MVS system input.

  • Procedure ISGAJE3A for resource report with multiple MVS systems input. The output generated is shown in Figure 4.

    Programs used are ISGAMEDM - ISGAMCNT - ISGAMSRT - ISGAMERN and SORT.

    For each major name the following is given:

    • Count of ENQ requests.
      Note: If DEQ is issued for each ENQ, the total count of requests for the resource is doubled.
    • Scope of the request.
    • SMF system id.
    • List of minor names used with the RNL action:
      1. *C reserve-converted --> SYSTEMS and NO-HW-RESERVE
      2. *E reserve-excluded --> SYSTEM and HW-RESERVE
      3. *E systems excluded --> SYSTEM
      4. *I system included --> SYSTEMS
      5. N keyword RNL=NO
      6. 'blank' no action
      7. Length of the minor name (ML).
      8. Timing information for reserve requests.
