Facility Codes
Ingres facility codes consist of a two-character code that is generated by a particular facility. For example, the Abstract Data Type Facility has a facility code of AD so error messages generated by this facility have an error message format of:
E_ADxxxx_msg
Error messages often include an explicit reference to which internal function returned the error. A list of these modules and their functions can help you identify the source of errors requiring troubleshooting.
Facility Codes for Primary Components
The facility codes for the primary Ingres components, such as the DBMS Server and General Communications Facility, are shown in the following table:

Server-Only Components
The server-only components are mostly DMF routines. The facilities listed in the following table are all subcomponents for Compatibility Library (CL) and do not appear in the facility-code part of an error message. All messages involving these facilities start with E_CL, and usually contain the two-letter facility code in the abbreviated message part of the error text.
