Check the Ingres Character Set
To check the character set of the Ingres installation, first obtain the Ingres installation ID by issuing the following command at the installation's command prompt:
ingprenv II_INSTALLATION
To display the character set, issue the following command using the returned ID value for xx:
ingprenv II_CHARSETxx
Example: Ingres Installation Check
c:\>ingprenv II_INSTALLATION
II
c:\>ingprenv II_CHARSETII
WIN1252
Windows
Windows users can check the character set by viewing the installation's II_CHARSETxx parameter value in Ingres Visual Manager.
Important! Do not change the Ingres installation character set without first understanding how the change will affect stored data. You risk corrupting existing data if that data does not support the new character set. It is preferable to change the DBMS character set if incompatibilities exist.
