CAL2JCL Member: AL2GEN (or AL2UGEN if an upgrade. See the note.)
Return Code: 0
Installation Type: Both new and upgrade environments
Upgrade Note: A full SYSGEN is required if you are installing the product for the first time. And we recommend a full SYSGEN even if you are upgrading from a previous release. Many things have changed in this release. If you execute a full SYSGEN, you can compare the resulting JCLLIB with the JCLLIB that you currently have. This output makes it easier to make the necessary changes.
Several JCL and procedure members have been eliminated, as have some user exits. The CA Datacom/AD libraries that are needed for execution are included in many of the JCL STEPLIB concatenations. Numerous changes have occurred in the CA7ONL initialization file also.
Create a CA WA CA 7 Edition SYSGENed JCLLIB library instead of overlaying your existing CA 7 r11.3 JCLLIB. This method provides for a fall back (reversion) and also permits a comparison for differences. For example, the Database Transportability (DBT) JCL set has changes to point to CA Datacom/AD. Several DD statements pointing to the old files have been removed.
Important! Notify the users to replace all CA WA CA 7 Edition JCL and procedures that they have in private libraries.
Description: Prepares for the generation of a CA WA CA 7 Edition JCL Library (JCLLIB). The JCL library contains installation jobs and supporting files to install CA WA CA 7 Edition on your system.
The Master Preparation Checklist contains a list of all the data that can assist with creating the input to the SYSGEN process.
The input for this process is a series of macros setting selected data sets, options, and parameters. The output from the CA WA CA 7 Edition Stage I assembly is a card-image IEBUPDTE job. The job contains all the required files to create the CA WA CA 7 Edition JCL library (JCLLIB), which is used in Stage II of the CA WA CA 7 Edition installation process. In the AL2GEN member, adjust the output to an appropriate location.
If you are upgrading, the best way to perform a Version 12.0 SYSGEN is to modify your existing SYSGEN macros. Locate your previous SYSGEN, which can be located in a sample JCL library (SAMPJCL or other location depending on release). Look for member L2xxGEN, where xx is the release number (L2B3GEN for r11.3, L2B1GEN for r11.1). If not renamed, the name can still be CA7GEN in the previous release.
Create a copy of the previous SYSGEN job renaming it CA7GEN. Delete all the JCL surrounding the CA WA CA 7 Edition macros (they begin immediately after the //SYSIN DD * statement). Use the following guidelines to update the SYSGEN macros. If you cannot locate a previous SYSGEN job, use member AL2GEN in the CA WA CA 7 Edition JCL library CAL2JCL to create one.
The SYSGEN parameters that have changed in Version 12.0 include the following:
Remove the following keywords from the macro specified:
|
Macro |
Keywords Removed |
|---|---|
|
U7PARMS |
DBDYNA |
|
U7PNAMES |
ARK, ARL, BKUP, VBK, VRL |
|
U7SPACE and U7VOL |
ARF, DMPQ, DMPV, IDS, QACT, QDQT, QPRE, QPRN, QPST, QRDY, QREQ, QSCR, QTRL, SASDS, SASJOB, VRM |
|
U7GEN |
QUNIT |
Add to the U7PARMS macro the following keywords related to CA Datacom/AD:
DBNAME, CAAXLOAD, and CUSLIB.
Once you have coded the Version 12.0 SYSGEN macros, copy and edit member AL2UGEN in the CA WA CA 7 Edition JCL library CAL2JCL. Follow the directions in the comment area. Run the AL2UGEN job to create the Stage I output (member STAGE1). This output contains model JCL that you use in the next job.
The following items describe the CA WA CA 7 Edition Stage I SYSGEN macros (some are optional):
(Required) Specifies the system PARMs. This one must be first.
(Required) Specifies the JCL data sets that the CA WA CA 7 Edition system can use.
(Required) Specifies the JOB statement operand information that is placed on the generated Stage II installation jobs.
(Required) Specifies global parameters. This one must be last.
(Optional) Specifies the direct-access volumes that CA WA CA 7 Edition can access.
(Optional) Specifies CA WA CA 7 Edition VTAM, TSO/ISPF, and other system interface parameters.
(Optional) Overrides the default names for the generated CA WA CA 7 Edition JCL procedures.
(Optional) Overrides the default space allocation parameters for the CA WA CA 7 Edition files.
(Optional) Specifies the values that the generated sample test job stream and the log tape dump jobs use.
(Optional) Specifies the volume and unit parameters for the CA WA CA 7 Edition files.
These macros and their parameters are described in detail in Stage I SYSGEN Macros.
Coding Notes
The following items are notes for coding the CA WA CA 7 Edition Stage I SYSGEN macros:
Assemble the Stage I macros and examine the output for error messages. If any errors occur, correct the problems. Next, rerun the assembly until it runs cleanly. When you have a clean Stage I assembly, continue to the next installation step.
The output is set up to go to the STAGE1 member in the library that you selected.
