After installing and configuring the CA DB2 products the invocation of the RSPMAIN CLIST fails with the following error:
1 +++ PROC 0 HIGHLVL(CAI.DB2TOOLS) +
IRX0043I Error running RSPMAIN, line 1: Routine not found
This specific problem condition was caused by placing the RSPMAIN CLIST in the SYSEXEC concatenation which is for REXX EXECs.
To dynamically pick up the RSPMAIN CLIST (without using the ALTLIB process) place the RSPMAIN CLIST in the SYSPROC concatenation (which is for CLISTs), and not the SYSEXEC concatenation.
