MasterdataObject object error, when connecting to databases with ClearQuest tools



This technote explains how to resolve an error, "There is a reference to an object that does not exist: Object Type: MasterdataObject". This can occur when connecting to databases with IBM Rational ClearQuest Designer or User Administration tool.


Here is the full error message:

An error was detected retrieving information from the ClearQuest database.
There is a reference to an object that does not exist:
Object Type: MasterdataObject
Object: <dbid>
This error was detected at: ClearQuest Core:admasterdatamgr.cpp:2460
Recommendation: If you cannot determine how to resolve this issue, contact Rational Support and provide all the above information as well as a description of the context in which the message occurred.

The error can occur when you perform an activity in a ClearQuest administration tool that connects to the database. Such activities include deleting a database in ClearQuest Designer, or viewing database subscriptions in the User Administration tool.


The database contains a reference to a user account that no longer exists. This can happen when:

  • There is a communication problem during database activity that prevents that activity from completing successfully. Specifically, database references to the user account are not completely updated or deleted.
  • ClearQuest databases have been restored from backup, but the restoration process is either incomplete or performed incorrectly.

Note: Similar error messages can occur as the result of separately identified defects. See the links in the Related information section of this technote for more information.

Resolving The Problem

A workaround for this problem is available. It requires the guidance of a ClearQuest Support Engineer. Contact IBM Rational Support for more information.


Always make new database back-ups of your schema repository and user databases prior to making schema changes and performing database upgrades. Failure to create back-up copies can limit your ability to recover from a an upgrade failure, design change issues or other unforeseen failures.
