Issue/Introduction

Where are all places an SVC number can be specified for an IDMS CV

Resolution

The main place to specify the SVC number used by an IDMS CV is in the Sysgen SYSTEM statement.

This SVC number can also be overridden in the startup JCL with startup parameter SVC=

The other important place where the SVC number must be specified is in the #SECRTT TYPE=INITIAL macro when creating the RHDCSRTT security table.  The RHDCSRTT module used by the CV must specify the same SVC as specified  in sysgen and/or SVC= startup parameter.

Other places where an SVC number can be specified. These are for external programs to access a CV:

IDMSOPTI - this is not typically used as SYSCTL is the standard way for an external program to access a CV.

CICSOPT and IDMSINTL - the  recommendation is to specify a SYSCTL ddname but you do have the option of hard coding the SVC and CV numbers in these CICS macros that are used to create CICS interfaces to an IDMS CV.
