The HCL Informix database is embedded in the CMS application. CMS users do not log in to the Informix database or have any privileges within the Informix subsystem. All access to the Informix database is via the CMS application.

An optional ODBC or JDBC interface is available. Customers must activate and set up the ODBC or JDBC connection. The ODBC or JDBC connection can be configured for TLS or SSL encryption. This interface allows direct SQL queries of the Informix database but does not allow any CMS data changes.

Customers can use the ODBC or JDBC interface to create custom tables in the database available for use when creating CMS Supervisor Designer reports.

For more information about the ODBC or JDBC interface used with CMS, including details on how to restrict which logins have access to this interface and how to configure TLS or SSL encryption, see Using ODBC and JDBC with Avaya Call Management System.
