An IBM Informix gateway acts as a bridge between an Informix application (in this case, a database server) and a non-IBM Informix database server. An IBM Informix gateway allows you to use an IBM Informix application to access and modify data that is stored in non-Informix databases.
The following table lists the gateways and corresponding database servers that can participate in a transaction in which the database server uses the heterogeneous commit protocol.
| Gateway | Database Servers |
|---|---|
| IBM Informix Enterprise Gateway with DRDA | IBM DB2, OS/400, SQL/DS |
| IBM Informix Enterprise Gateway for EDA/SQL | EDA/SQL |
| IBM Informix Enterprise Gateway Manager | Any database server with ODBC connectivity |
