1.7.1 IIOP Listener and Handler

The IIOP Listener (ISL) enables access to Oracle Tuxedo CORBA objects by remote Oracle Tuxedo CORBA clients that use IIOP. The ISL is a process that listens for remote CORBA clients requesting IIOP connections. The IIOP Handler (ISH) is a multiplexor process that acts as a surrogate on behalf of the remote CORBA client. Both the ISL and ISH run on the application site. An application site can have one or more ISL processes and multiple associated ISH processes. Each ISH is associated with a single ISL.

The client connects to the ISL process using a known network address. The ISL balances the load among ISH processes by selecting the best available ISH and passing the connection directly to it. The ISL/ISH manages the context on behalf of the application client. For more information about ISL and ISH, see the description of ISL in the File Formats, Data Descriptions, MIBs, and System Processes Reference.
