Server Classes
If you do not specify a server class when connecting to a database, Ingres assumes a default. The default is the value in default_server_class on the remote instance (ingres, unless defined otherwise).
Valid Ingres server classes are as follows:
ingres
Indicates DBMS Server
star
Indicates Star Server (Ingres Ingres Star)
db2
Indicates EDBC for DB2
db2udb
Indicates Enterprise Access for DB2 UDB
rdb
Indicates Enterprise Access for RDB
ims
Indicates EDBC for IMS
rms
Indicates Ingres RMS Access
vsam
Indicates EDBC for VSAM
mssql
Indicates Enterprise Access for MS SQL
oracle
Indicates Enterprise Access for Oracle
informix
Indicates Enterprise Access for Informix
sybase
Indicates Enterprise Access for Sybase
To view or change the default server class value, use the Configure Name Server screen of the Configuration-By-Forms (cbf) utility, or the Parameters Page, Name Server Component in Configuration Manager (vcbf).
The server class for the DBMS Server (default is ingres) and Star Server (default is star) can also be changed. This is typically done to distinguish between multiple DBMS or Star servers that have different sets of parameters, so that users can connect to a specific server using an assigned server class name.
Additional server types are added to this list as additional Enterprise Access or EDBC products are developed. Check the Readme file for the most up-to-date set of products.
