DRDA Support Functions

Informix® provides built-in functions that support the Distributed Relational Database Architecture™ (DRDA®) protocol when the Informix instance is configured as a DRDA application server. This is accomplished by setting DBSERVERALIASES to DRDA in the configuration file.

• The sysibm.Metadata function provides database metadata information to Data Server Driver for JDBC and SQL client applications.
• The sysibm.SCLCAMessage function supports DRDA error handling.

The Metadata and sqlcaMessage routines are created automatically if the database server is configured to support the DRDA protocol. The Informix implementation of these functions conforms to the DR Level 5 SQLAM 7 standard
