Description:

The CA Workload Automation and Job Management products now use a new CA 11 r11 interface to modify restart information forjobs. Since JES nodes can be physically remote, CA 11 communicates with the CA GTS component to send updates to other remotes (usually over TCP/IP).

Solution:

Customers that have more than one JESPLEX executing within the same sysplex and serviced by the same CA Datacom MUF can now use the configuration file parameter LOCALGTS=NO to eliminate the overhead of requiring CA GTS when the scheduler sends a request with a remote node field specified.

If you specify LOCALGTS=NO, you must be sure that all requests to CA 11 that specify a JES node is serviced by the local CA Datacom MUF. Every system in each JES node given to CA 11 must be using the same CA Datacom MUF that DBAS uses.

The ISPF dialog now displays the LOCALGTS value on the main menu so the user can see if the subsystem has LOCALGTS=NO. If LOCALGTS is not specified or set to NO, the ISPF dialog panels have the Remote field set to "N/A" to remind you that specifying the remote value is not going to be valid.

In order to take advantage of GTS when using CA WA Restart Option (CA 11) r11, the following steps will need to be completed:

  1. CA GTS (FMID CD51110) needs to be installed.

    Note: CA GTS is not installed by default with CA WA Restart Option (CA 11), because other CA products use CA GTS and it may have already been installed. In any event, some minor customizations will be necessary to use CA GTS with CA WA Restart Option (CA 11) r11.

  2. CA GTS requires access to the CA 11 CAL7LOAD, and the CA Datacom CUSLIB and CAILIB libraries. The CA GTS Product Code for CA WA Restart Option (CA 11) is BB. Specify this product code in the CA GTS Parmlib Member CLIENTxx as follows:

    PRODUCT(IDENTITY(BB) MODULE(CAGSBBLD))

    This parameter is the only CA WA Restart Option (CA 11) specific parameter needed. However, some CA GTS Parmlib members can adversely affect CA WA Restart Option (CA 11) if coded incorrectly.

    Verify that the CA GTS Parmlib member GSINITxx includes XMEM(YES) (this value is the default if omitted).

    Code the CA GTS Parmlib members TCPIPCxx and TCPIPSxx so that all remote locations that CA WA Restart Option (CA 11) is to access are defined as both Client and Server.

  3. Lastly, ensure that the GTSHLQ is defined in the C11ILIBD REXX EXEC, as shown below:

    If GTSHLQ == "" then GTSHLQ = "gtshlq" /* USER */
