SAS/ACCESS Interface to IMS-DL/I Software |
Executing a Cataloged Procedure |
The JCL for a batch job accessing
IMS data requires that you specify your site's designated cataloged procedure
in the EXEC statement. So, instead of specifying your site's default SAS
cataloged procedure (such as
// EXEC SAS
), you use the following
EXEC statement:
// EXEC your-cataloged-procedure
The name of the cataloged procedure that invokes the SAS System and supports the use of the SAS/ACCESS interface to IMS-DL/I differs at each installation, particularly if your installation uses separate cataloged procedures for accessing test databases and production DL/I databases. Be sure to check with your site's SAS support consultant for the correct procedure name. (SAS Institute no longer supplies the Version 5 SASDLI cataloged procedure.) The installation notes that are shipped with the SAS/ACCESS interface to IMS-DL/I explain to your database administrator how to create a cataloged procedure for your site.
The cataloged procedure for accessing IMS-DL/I data contains all of the JCL statements and parameters that the SAS cataloged procedure contains, plus JCL statements and parameters necessary for the run-time execution of the IMS-DL/I engine interface and IMS-DL/I DATA step programs. PROC ACCESS can use the standard SAS catalog if the only task you are performing is creating descriptor files.
DD Statements |
If you execute DL/I calls through an online DL/I access region (BMP), database data sets are allocated to the DL/I control region or to the CICS control region. Therefore, you do not need to include DDnames for them in the job step JCL.
When you execute a batch DL/I region and want to log updates, you need a DD statement for a log data set. For information on using the IMSLOG option, on pointing to the IMS-DL/I resident libraries, and information on pointing to the DBD, PSB, and ACBLIB, check with your DBA or refer to the installation instructions for the SAS/ACCESS interface to IMS-DL/I.
All other JCL considerations that are outlined in the SAS Companion for the OS/390 Environment apply to the IMS-DL/I engine interface and IMS-DL/I DATA step execution.
