gtpa1m0gACF/SNA Network Generation

Using the OSTG Program

Figure 3 shows how the required information is defined and passed from SIP to the TPF online routines through the various stages.

Figure 3. OSTG Overview


The SNA network definition process consists of the following steps:

  1. Code the MSGRTA macros in the SIP process for the TPF applications that you want to define to the TPF system being generated. See TPF ACF/SNA Data Communications Reference for information about the applications to define to the TPF system using the OSTG program.

    The MSGRTA macros will cause the SIP process to generate the application name table (ANT) deck that is needed as input to the OSTG program. See ANT Deck for information about the ANT deck.

  2. Code the RSC deck for the CDRM resources and remote LU resources that you want to define to the TPF system being generated.

    See TPF ACF/SNA Data Communications Reference for information about the CDRM resources and remote LU resources to define to the TPF system using the OSTG program. See RSC Deck for information about the RSC deck.

  3. Code the ALS deck for the channel-attached NCP, CTC, or ALS resources that you want to define to the TPF system being generated. This includes the resources that will be connected as PU 4 nodes and the resources that allow the TPF system to connect as a PU 2.1 node.

    See TPF ACF/SNA Data Communications Reference for information about the NCP, CTC, and ALS resources to define to the TPF system using the OSTG program. See ALS Deck for more information about the ALS deck.

  4. Prepare the JCL to run the OSTG program. See Figure 15 and Figure 16 for examples of the JCL needed to run the OSTG program.
  5. Run the OSTG job step and review the output reports. You may need to run the OSTG program several times to eliminate all of the errors that can occur when you define a large network.
  6. After the OSTG program is run successfully with no errors, load the resulting pilot tape or GDS to the online TPF system.
  7. Perform a soft initial program load (IPL) on the TPF system to include the new SNA network definitions.
