Starting and stopping components

This procedure explains how to start or stop an XBM component. You can use either the ISPF interface or the MVS system console.

Warning

Important

During the initial start of an  subsystem, all authorized components will be started. If that  subsystem is stopped, only those components that were active when the  subsystem was shut down will be active when the  subsystem is restarted. If a component was stopped or inactive when the  subsystem was stopped, that component will need to be manually restarted after  restarts. The only exception to this if the started task includes a XDB2, XIMS, XVSAM, XSSI, XPSS, or XZIIP keyword that specifies to start that component upon restart.

To start or stop components by using the ISPF interface

  1. From the File List panel, choose Console > Components and press Enter to display the Console - Component subpanel as shown in the following figure:

  2. In the Name field, type the name of the component that you want to stop or start.

    Warning

    Important

    You can use pattern-matching characters in this field. For example, type * in the Name field to stop or start all components. For more information, see Understanding-XBM-pattern-matching-and-query-options.

  3. In the Command field, type 3 (Stop) or 2 (Start) and press Enter to stop or start the component.

    Warning

    Important

    In a data sharing environment, you can start or stop a PSS component only by using the  ISPF interface on the same system as the  subsystem. To start or stop a PSS component on another system, you must use the MVS console.

To start or stop components by using the MVS system console

You can use the MVS system console to stop and start XBM components.

  1. To stop the component from the MVS system console, use the following command:

     ssid STOP COMPONENT componentName

    The variable ssid represents the name of the XBM subsystem, and the variable componentName represents the XBM component (Db2, IMS, PSS, SSI, VSAM, ZIIP, or *) that you are stopping.

  2. To start the component from the MVS system console, use the following command:

     ssid START COMPONENT componentName

    The variablessid represents the name of the XBM subsystem, and the variable componentName represents the XBM component (Db2, IMS, PSS, SSI, VSAM, ZIIP, or *) that you are starting.

    Success

    Tip

    In a data sharing environment, you can use the  ROUTE command to start or stop any  component (except the PSS component) in the data sharing group. Use the following command:

     xbmgroup ROUTE ssid STOP COMPONENT componentName

    The variables represent the following values:

    • xbmgroup represents the name of the XCF group.
    • ssid represents the name of the  subsystem.
    • componentName represents the  component (Db2, IMS, SSI, VSAM, ZIIP, or *) that you are stopping or starting.
    Warning

    Important

    Specifying an XCF group name on the  start command overrides both the XBMGROUP parameter on the  PROC and the group name on the PSS Options subpanel.
