Subcomponent identifiers in Db2 messages and codes
The identifiers for messages or reason codes in Db2 indicate the associated Db2 subcomponent or functional area.
The following table lists the Db2 subcomponents and functional areas and the identifiers that are associated with each one. Some message identifiers are shared by more than one subcomponent or functional area. Also, subcomponents can call each other, so one subcomponent might return messages with reason codes from another.
