Explanation
DB2® was unable to open a required index data set because the index was formatted incorrectly. For example, it may have been formatted as a Type 1 index when the DB2 catalog indicates that it should be Type 2.
The reason code and index data set name are made available in the SQL communication area or in related messages.

A 'resource unavailable' code is returned to the user.
