Requesting a dump for a JVM (PTF BPF0457 applied)

Use the following procedure to request a dumps type for a JVM.

To request a dump

  1. On JVMDISC, type DMP in the CMD column for a JVM.

  2. In the Dump Java Virtual Machine dialog, type S next to one or more dump types: 

    • SVC Dump
    • Java Core Dump
    • Java Heap Dump (Liberty JVMs only)
    • Server Dump (Liberty JVMs only)
    +------------------------- Dump Java Virtual Machine -------------------------+
    | COMMAND ===>                                              SCROLL ===> CSR   |
    |                                                                             |
    | JVM's information:                                                          |
    | Job Name BAQSTSMN                                                           |
    | JVM Type Zconnect                                                           |
    | PID      50921755                                                           |
    | ASID     00C5                                                               |
    |                                                                             |
    | Dump options:                                                               |
    | Use 'S' to select.                                                          |
    | _ SVC Dump                                                                  |
    | _ Java Core Dump                                                            |
    | _ Java Heap Dump                                                            |
    | _ Server Dump    (Core/Heap dumps are included in the dump package)         |
    |                                                                             |
    | Time out interval: 10 (In seconds. Default is 10 sec [Integer])             |
    |                                                                             |
    | EXEC to request DUMP                                                        |
    | CANcel to exit without requesting a DUMP                                    |
    | HELP to display help                                                        |
    |                                                                             |
    +-----------------------------------------------------------------------------+

  3. In the Time out interval field, specify the number of seconds that you want to wait for a response.

    Important

    • If you specified a Server dump, consider setting this value to 10 seconds (the default).
    • This field is valid only for Liberty JVMs.

  4. On the command line, type EXEC.

    Important

    If BMC AMI OpsMJE detects that a Liberty JVM has an identical job name and job identifier, the dialog displays a warning message.

    If you have only one Liberty JVM with an identical job name and job identifier, BMC AMI OpsMJE requests a dump for that JVM. However, if you have multiple Liberty JVMs with an identical job name and job identifier, BMC AMI OpsMJE requests a dump for all instances of the JVM.

    You can check whether multiple JVMs are running with the same job name and job identifier by comparing the values in the Job Name and Step Name fields.

    When the dump has finished, OK is displayed in the CMD column.

  5. View the status of the dump in the JVM's Job log. For Liberty JVMs, the name and location is also displayed.

    Important

    • (For non-Liberty JVMs) SVC dumps contain the ASID of the BMC AMI OpsMJE PAS and the ASID of the JVM on which you requested a dump. You can see a message about the requested dump in the PAS log.
    • For IMS JVMs, the dump is generated when the JVM shuts down, or when the IMS is receiving signals.
    • The default directory for Java core and heap dumps is your home directory. For more information about changing the location of the dumps, search for the following topics in the IBM documentation:
