Using the WebSphere MQ for z/OS dump display panels

WebSphere MQ for z/OS provides a set of panels to help you process dumps. The following section describes how to use these panels:

  1. From the IPCS PRIMARY OPTION MENU, select ANALYSIS - Analyze dump contents (option 2).

    The IPCS MVS(TM) ANALYSIS OF DUMP CONTENTS panel appears.

  2. Select COMPONENT - MVS component data (option 6).

    The IPCS MVS DUMP COMPONENT DATA ANALYSIS panel appears. The appearance of the panel depends on the products installed at your installation, but will be similar to the panel shown below:

    ---------------- IPCS MVS DUMP COMPONENT DATA ANALYSIS -------------
    OPTION ===>                                               SCROLL ===
     
    To display information, specify "S option name" or enter S to the
    left of the option desired.  Enter ? to the left of an option to
    display help regarding the component support.
     
      Name     Abstract
      ALCWAIT  Allocation wait summary
      AOMDATA  AOM analysis
      ASMCHECK Auxiliary storage paging activity
      ASMDATA  ASM control block analysis
      AVMDATA  AVM control block analysis
      COMCHECK Operator communications data
      CSQMAIN  WebSphere MQ dump formatter panel interface
      CSQWDMP  WebSphere MQ dump formatter
      CTRACE   Component trace summary
      DAEDATA  DAE header data
      DIVDATA  Data-in-virtual storage
  3. Select CSQMAIN WebSphere MQ dump formatter panel interface by typing s beside the line and pressing Enter.

    If this option is not available, it is because the member CSQ7IPCS is not present; you should see the WebSphere MQ for z/OS System Setup Guide for information about installing the WebSphere MQ for z/OS dump formatting member.

    Note:
    If you have already used the dump to do a preliminary analysis, and you want to reexamine it, select CSQWDMP WebSphere MQ dump formatter to display the formatted contents again, using the default options.
  4. The IBM(R) WebSphere MQ for z/OS - DUMP ANALYSIS menu appears. Use this menu to specify the action that you want to perform on a system dump.

    ---------------IBM WebSphere MQ for z/OS - DUMP ANALYSIS----------------
     COMMAND ===>
     
     
     
          1 Display all dump titles 00 through 99

  5. Before you can select a particular dump for analysis, the dump you require must be present in the dump inventory. To ensure that this is so, perform the following steps:
    1. If you do not know the name of the data set containing the dump, specify option 1 - Display all dump titles xx through xx.

      This displays the dump titles of all the dumps contained in the SYS1.DUMP data sets (where xx is a number in the range 00 through 99). You can limit the selection of data sets for display by using the xx fields to specify a range of data set numbers.

      If you want to see details of all available dump data sets, set these values to 00 and 99.

      Use the information displayed to identify the dump you want to analyze.

    2. If the dump has not been copied into another data set (that is, it is in one of the SYS1.DUMP data sets), specify option 2 - Manage the dump inventory

      The dump inventory contains the dump data sets that you have used. Because the SYS1.DUMP data sets are reused, the name of the dump that you identified in step 5a might appear in the list displayed. However, this entry refers to the previous dump that was stored in this data set, so delete it by typing DD next to it and pressing Enter. Then press F3 to return to the DUMP ANALYSIS MENU.

  6. Specify option 3 - Select a dump, to select the dump that you want to work with. Type the name of the data set containing the dump in the Source field, check that NOPRINT and TERMINAL are specified in the Message Routing field (this is to ensure that the output is directed to the terminal), and press Enter. Press F3 to return to the DUMP ANALYSIS MENU.
  7. Having selected a dump to work with, you can now use the other options on the menu to analyze the data in different parts of the dump:
