Updating VTAM

This section describes the steps you must complete to update VTAM.

Warning

Note

If you want to base your VTAM definition statements on BMC-provided sample statements, use the sample statements from member DLA$APPL of the DLASAMP library.

 

  1. Assemble and link-edit the VTAM mode table.The VTAM mode table is supplied in member DLA#MODE of the DLACNTL library. You must assemble and link-edit the mode table into SYS1.VTAMLIB or its equivalent.

  2. Create TSO/ISPF APPL definition statements in SYS1.VTAMLST for each TSO system that will run the DELTA IMS online interface.Use the following guidelines when you create TSO/ISPF APPL definition statements:

    • TSO LU names must be unique throughout your VTAM network.
    • TSO ACBNAMEs must be unique only within a given MVS system.
    • TSO ACBNAMEs must use the format prefnnnn, where pref is a four-character prefix used for all BMCLINK ACBNAMEs and nnnn is a number in a sequence that starts with 0001.
    • BMC recommends that the TSO session identifier that begins each TSO/ISPF APPL definition statement match the corresponding TSO ACBNAME; however, a match is not required.

    The following figure shows sample statements. Sample VTAM statements are also available in member DLA$APPL of the DLASAMP library.

    Sample TSO/ISPF APPL statements

    DLAU0001  APPL  AUTH=(ACQ,PASS),MODETAB=DLAMODE,  X
                    DLOGMOD=DLAMOD1,EAS=1,            X
                    ACBNAME=DLAU0001
    DLAU0002  APPL  AUTH=(ACQ,PASS),MODETAB=DLAMODE,  X
                    DLOGMOD=DLAMOD1,EAS=1,            X
                    ACBNAME=DLAU0002
    DLAU0003  APPL  AUTH=(ACQ,PASS),MODETAB=DLAMODE,  X
                    DLOGMOD=DLAMOD1,EAS=1,            X
                    ACBNAME=DLAU0003
    DLAU0004  APPL  AUTH=(ACQ,PASS),MODETAB=DLAMODE,  X
                    DLOGMOD=DLAMOD1,EAS=1,            X
                    ACBNAME=DLAU0004
    DLAU0005  APPL  AUTH=(ACQ,PASS),MODETAB=DLAMODE,  X
                    DLOGMOD=DLAMOD1,EAS=1,            X
                    ACBNAME=DLAU0005

     

    Create one BMCLINK APPL statement for each BMCLINK started task that you will use. BMCLINK LU names must be unique throughout your VTAM network.

    The following figure shows a sample statement.

    Sample BMCLINK APPL statement

       BMCL0001 APPL AUTH=(ACQ,PASS),EAS=10
    Warning

    Note

    One BMCLINK started task can be used to communicate with multiple IMS systems on the same CPU. You do not need to create a separate BMCLINK or APPL statement for each IMS system.

  3. Create CDRSC statements if necessary.

     

    If the online interface and BMCLINK

    Then

    Run on the same MVS system

    Go to Step 4.

    Do not run on the same MVS system in some or all cases

    Use the following guidelines to create CDRSC statements.

     

    Follow these guidelines when creating CDRSC statements:

    • Each CDRSC LU name must match the LU name of the BMCLINK APPL statement that defines the BMCLINK task for the IMS system.
    • The CDRM= parameter must identify the minor node where the BMCLINK task and IMS system will run.

    The following figure shows sample statements.

    Sample CDRSC definition for MVST system

              VBUILD TYPE=CDRSC
    DLAL0001  CDRSC  CDRM=cdrmid
              VBUILD TYPE=CDRSC
    DLAL0002  CDRSC  CDRM=cdrmid
  4. Verify that the SYS1.VTAMLST member names, LU names, and ACBNAMEs that you created conform to your site’s standards and the requirements that are specified in this task.
  5. If you have the required authority, activate the VTAM definition statements. Otherwise, verify that the definitions have been activated before proceeding with the configuration process.
