Setting up IMS or DB2 batch job redirection

To set up batch job redirection, you need to install and prepare APPLICATION RESTART CONTROL and MainView Batch Optimizer, and to configure the BMC Configuration Component for z/OS (LGC) common component.

 

Note

The IMS Control Region must have a IMS APPLCTN definition and an ACB that matches the PSB specification for the DLI/DBB batch job; just like a BMP.

Subzero does not support the following implementations for IMS batch job redirection:

  • Remote access to the I/O or to the alternate I/O program communication blocks (PCB).

    Subzero cannot redirect the application program to access the IMS I/O PCB or Alternate I/O PCB on a remote IMS system. Also, Subzero cannot redirect access to the IMS message queues (no transaction-oriented BMP support) or to the IMS command interface.

  • Remote access to Generalized Sequential Access Method (GSAM) databases.

    AR/CTL for IMS will automatically enabled its own Application Sequential Access Method (ASAM) to access GSAM databases. For more information, contact BMC Customer Support.

  • A Processing Option (PROCOPT) of L (Load) or LS (Load Sequential) is only valid for GSAM databases.  It is not valid for Fast Path, HALDB or Full Function database access.
    The PSB is the third parameter of the BMP/DLI/DBB execution parameter.

  • Subzero cannot connect to IMS DCCTL subsystems.  

    You must connect to an IMS DBCTL or IMS DB/DC system in order to access IMS databases.  If you currently use IMS DCCTL to provide DB2 access for your IMS applications, this can be replaced with ARC for local DB2 connectivity or ARC with Subzero for remote DB2 connectivity.
    The PSB used by the batch program, must be defined to the IMS system.  For example:

     APPLCTN PSB=name,PGMTYPE=BATCH,SCHDTYP=PARALLEL

    Note

     Your parameters may vary depending on your environment.

Complete these tasks

Using these instructions

MainView Batch Optimizer

Create a new job policy in the control data set, add the DIRECT action to the policy's global options, and activate the policy.

Add the DIRECT JTL statement for each job that you want to execute on a remote subsystem.

Edit the MainView Batch Optimizer Subsystem commands member to activate the Subzero for DB2 interface at startup.

LGC

Configure the redirection information for the client and target subsystems.

APPLICATION RESTART CONTROL

Edit the AR/CTL BCSS started task.

Add the AR/CTL program registration record and update it with record key values.

Add the Subzero subsystem program registration record and update it with record key values.

Add the Subzero load library DSN to the non-IMS environment record.
