IPCS VERBEXIT subcommand to display diagnostic data

The interactive problem control system (IPCS) is a tool that provides formatting and analysis support for dumps and traces produced by WebSphere® Application Server for z/OS® and the applications that it hosts.

IBM® service personnel might request that you use the IPCS subcommand VERBEXIT with the BBORDATA verb name to display dump information for WebSphere Application Server for z/OS. The BBORDATA formatters reside in the WAS_HOME/lib/ipcs/ directory, which must be copied into a dataset that is in the link list or LPA

Entering VERBEXIT BBORDATA results in a display of dump contents that can include the following WebSphere Application Server for z/OS structures:

Optional parameters control which of these structures are included in the dump display. If you enter VERBEXIT BBORDATA without any optional parameters, the dump display includes only global control block content

To enter VERBEXIT BBORDATA, you might use any of the methods for entering IPCS subcommands on z/OS, as described in z/OS MVS™ IPCS User's Guide, SA22-7596. Use the following syntax: VERBEXIT BBORDATA [ 'parameter [,parameter]...' ]

Valid parameters are:
  • GLOBAL(bgvt-address)
    Formats and displays cell-level global vector data for the specified address space. This display includes the following formatted control blocks:
    • BGVT address - z/OS Global Vector table
    • ASR Table and ASR Table entries - Active Server Resposity information
  • ASID(asid-number)
    Formats and displays address space information for the daemon, the controller (region), or the servant (region). This display includes the following formatted control blocks:
    • BACB - z/OS address space control block
    • BTRC,TBUFSET,TBUF - z/OS Component trace control blocks
    • BOAM,BOAMX - z/OS BOA control blocks
    • ACRW queue - Application Controller Work element control blocks
    • BTCB queues - z/OS control information
    Along with ASID(asid-number), IBM service personnel might direct you to specify one of the following parameters, to include additional information in the dump display:
    • BTCB(btcb_address)

      Formats and displays the specified BTCB and ORB information for the WebSphere Application Server for z/OS TCB.

    • COMMDATA

      Formats and displays session information.

    • CONFIG

      Formats and displays configuration information for the address space.

    • OBJADDR(object_address) and OBJTYPE(object_type_ID)

      Formats and displays information for the specified object of the specified type. IBM service personnel will provide the values for you to supply for these parameters.

    • ORBDATA

      Formats and displays ORB information.

    • TCB(tcb_address)

      Formats and displays request summary information for the specified task.

    • TRACEBACK

      Formats and displays ORB information.

  • SUMMARY

    Summarizes information from some of the other BBORDATA optional parameters. For example, for the GLOBAL parameter, specifying SUMMARY produces a list of active servers.

Example: Output from the command ip VERBEXIT BBORDATA 'ASID( xx ) TCB(yyyyyyyy )':


command ===> ip VERBX BBORDATA 'ASID(xx) TCB(xxxxxxxx)'
