TESTEXEC Data Set

The install utility populates the TESTEXEC data set based on the values entered during the installation and setup process.

Review the members in TESTEXEC to:

• Ensure that they meet your site-specific requirements
• Reapply any previous customization that is still required

Review the following members in dsnpref.rname.TESTEXEC:

NMREADY

Is the NCL procedure that is executed as part of system initialization after the VTAM ACBs have been opened successfully.

NMINIT

Is the NCL procedure that is executed as part of system initialization before the VTAM ACBs are opened.

Do not:

• Code any SYSPARMS commands in the NMINIT or NMREADY procedures.
• Activate or modify links, or use commands such as DEFLINK, DEFTRANS, and ISR in NMINIT or NMREADY. In a multisystem network, the region uses link definitions during initialization. Defining DEFLINK, DEFTRANS, and ISR in these procedures can interfere with region linkage.
