Setting global options

Use global options to specify parameters that govern DELTA IMS operations throughout your site, regardless of IMS system. You must review and save the global options if you are performing an initial installation of DELTA IMS.

DELTA IMS consists of various elements that are associated through VTAM and normal IMS inter-region communication. You must specify certain parameters to keep these elements operating according to the standards at your site. Global options apply to all TSO/ISPF sessions, batch functions, BMCLINK, and all control regions that DELTA IMS services. When you create or change global options, load module DLA$GBL0 is link-edited to your DELTA IMS options library.

Note

When global options are changed, other users must re-enter DELTA IMS to obtain the revised options. For proper operation, you should recycle BMCLINK.

To set global options

  1. Invoke the online interface through the modified ISPF/PDF Primary Option Menu that you created in Accessing DELTA IMS from an ISPF options menu or through the CLIST that you created in Accessing DELTA IMS from a CLIST.

    The Primary Menu is displayed.

  2. Type 5 in the selection field and press Enter.

    The Customization panel is displayed.

  3. Type 1 in the selection field and press Enter.

    The Global Options (Page 1 of 2) panel is displayed.

    The following fields are available on this panel:

    Four character prefix for BMCLINK session ACBNAME

    Specify the four-character prefix of the VTAM ACB name that is used for the TSO half of the VTAM LU-LU session with BMCLINK. The actual ACB name that is used will be the first available beginning with pppp 0001, pppp 0002, etc.

    A user session is established any time a user enters DELTA IMS. When necessary, a VTAM LU-LU connection is made between the DELTA IMS session and a BMCLINK task. This connection is known as a BMCLINK user session. The actual BMCLINK task that is contacted depends on the VTAM LU-name that is specified in the IMSID basic options for the specified IMS control region.

    The WTO message routing codes

    Specify one or more of the WTO routing codes, separated by commas, to be used by DELTA IMS and BMCLINK. BMCLINK issues WTO messages any time significant events occur. Use the WTO routing code to direct these messages to selected consoles.

    The WTO message descriptor codes

    Specify one or more of the WTO message descriptor codes, separated by commas, to be used by DELTA IMS and BMCLINK. BMCLINK issues WTO messages any time significant events occur. You can suppress these messages depending on the WTO message descriptor code specified.

    CHECK/EXECUTE pacing value (in 1/100s of seconds)

    Specify a pacing value in hundredths of a second to control the wait time between the execution of successive lines in a DELTA List. For example, if you specify a pacing value of 50, the Check and Execute functions check or execute the individual lines of a DELTA List at half-second intervals.

    Request status check time interval (in seconds)

    Specify the frequency between status messages, in seconds. BMCLINK periodically responds to the BMCLINK user session while processing a request for that session so that the user stays informed of the request processing status.

    Idle BMP automatic shutdown interval (in seconds)

    Specify the period of time, in seconds, after which BMCLINK should consider a BMP inactive and terminate it. BMCLINK communicates with an IMS control region by creating an IMS BMP task for that IMSID.

    Maximum DL/I command size (in bytes)

    Specify the size of the largest DL/I command to be issued through DELTA IMS. Commands and responses are shipped between BMCLINK and IMS when you execute and check DELTA Lists or process IMS commands. The value specified is the size of the area that is used to hold these commands and responses. The value must be the same as the value that is specified in the PSB IOASIZE field for the BMCLINK program (IMS and DBCTL control regions) and the BMCLINK transaction (IMS control regions only).

    The default is 1024 bytes, which is the recommended size. If you specify a value that is less than 1024 bytes, you cannot use the same BMCLINK to support communication for both DELTA IMS and ETA.

    BMCLINK ENQ qname

    BMCLINK uses ENQ/DEQ to serialize certain internal activities. The scope of the ENQ extends only to its address space, not to the entire system. If necessary, you can specify the ENQ qname and rnames to conform to the standards at your site.


    BMCLINK ENQ rname (VTAM interface)

    Specify the ENQ rname for the VTAM interface.

    BMCLINK ENQ rname (BMP control)

    Specify the ENQ rname for BMP control.

    IMSID options update ENQ qname

    DELTA IMS uses ENQ/DEQ to serialize the creation and modification of options that are associated with a given IMSID. Specify the systems level qname to be used to prevent concurrent access and overwrite of a given set of IMSID basic options.

  4. After you specify the information on the Global Options (Page 1 of 2) panel, press Enter.

    The Global Options (Page 2 of 2) panel is displayed.

    The following fields are available on this panel:

    Internal trace table size (in 1k multiples)

    Specify the internal trace table size, in 1024-byte increments. The Internal Trace facility is always active within BMCLINK. It maintains a log of all significant events in a virtual storage table, which is primarily intended for BMC diagnostic purposes. The trace table minimum recommended size is 16K.

    Internal trace table dynamic dump sysout class

    Specify the sysout class to be used if the internal trace table appears in any abend dumps. This class is also used if you must print the table on demand.

    Generic DASD unit name

    Specify the generic DASD unit name that the DELTA Log List function uses to allocate work files and temporary report files during sorts.

    User profiles data set name

    Specify the name of the data set where the user access profiles reside. This name is assigned at installation.

    Userid for authorization check

    Select one of the following options to indicate which user ID is presented to the User Authorization routine exit and recorded in the DELTA Log when a DELTA List Check or Execute is initiated:

    • 1 Active userid

    • 2 Last-update userid

    IMS operator commands

    Select one of the following options to allow all, some, or no IMS operator commands. For a graphic representation of these options, see Figure 3.

    • 1 Allow all commands

    • 2 Allow selected commands: Option 2 causes DELTA IMS to examine the user access profile and determine which IMS operator commands in the DELTA List are allowed.

    • 3 None allowed

      Note

      If user profiles are used to control access to IMSID-related functions, this value controls the ability to enter IMS commands from within DELTA Lists. If the SAF security interface is used, this value is ignored.

    The following figure shows the security hierarchy for commands in a DELTA List.
