Issue/Introduction

Error DC084110 can occur when a CV starts up. This may occur even in a system that has always worked fine, which has not had any changes to the sysgen or any changes relevant to the VTAM line. 

Environment

Release : 18.5 or 19/0; all supported releases

Component : CA IDMS/DB

Resolution

The DC084110 error indicates a problem with the VTAM line. It an be an error in the sysgen line definition, or a physical problem with the line. It can also be caused when there is a conflict between multiple CVs referencing the same VTAM APPLID in their line definitions. 

It may be possible for multiple CVs to specify the same APPLID, if only one CV uses them. In this situation, the order in which the CVs are started may impact whether the CV gets an error on the line at startup.

For example, if CV002 & CV002R both have a VTAM line definied with the same APPLID, and usually CV002 started up earlier than CV002R, that may cause no problem if CV002R does not use the connection. In that situation CV002 starts up first, and it uses the line, and all is fine because when CV002R starts up it does not attempt to actually open the line. Or it may attempt to open the line and gets the same error, but it is ignored because the line is not actually used. 

In this scenario, if for some CV002 is started up later than CV002R, that can cause the DC084110 in CV002. 

To resolve this, either:

1- startup the two CVs in the accustomed order; and/or

2- remove the duplicate APPLID definition from CV002R , shutdown both CVs and then bring up CV002 , and then bring up CV002R after.
