Environment

Release: All supported releases.
Component: IDMS Endevor DB

Resolution

This can be caused by the Endevor DB task trying to start but can't because of a dbname definition problem.

Endevor DB can be started when a user invokes the NDVR task code, or a startup autotask is defined in the sysgen. For example, in one system that uses Endevor, the DCMT D DBNAME shows the following DBNAME:

DBNAME SRCDICT MATCH ON SUBSCHEMA IS OPTIONAL
  SEGMENT SRCCCDB 0 BIND count
  SEGMENT SRCDICT 2 BIND count
  SEGMENT SYSMSG 0 BIND count
  SUBSCHEMA IDMSNWKA MAPS TO NDVRNWKA
 
As is shown above, there is a segment SRCCCDB - that is the Endevor segment. This dbname definition must also include a dictionary segment (SRCDICT) and the subschema mapping that is shown.
