This chapter describes how to use CA IDMS Server in the USS environment on z/OS. CA IDMS Server supports JDBC‑enabled applications running in the USS environment and client applications running on other platforms.
The JDBC driver always runs on the same platform as the client application. Applications running on z/OS use the JDBC driver on z/OS. The Type 2 JDBC driver uses the native SQL client interface to access the CA IDMS system through CAICCI/ENF. The Type 4 JDBC driver uses TCP/IP to communicate directly with CA IDMS r16 SP2 or later.
Remote client applications use a local (from the application's point of view) copy of the JDBC driver, which uses TCP/IP to communicate with the JDBC server on z/OS. The JDBC server acts as a proxy server, calling the native client interface on behalf of the Type 3 JDBC driver. Remote applications can also use the Type 4 JDBC driver to connect directly to CA IDMS r16 SP2 or later.
Important! Applications running on z/OS do not need the JDBC server to communicate with a CA IDMS system.
