5.2.1 Initialization

During initialization, the following activities occur:

• The runtime datasets (configuration file, message log, and server response log) are opened
• The configuration file is read and processed to establish the configuration
• The TMA TCP for IMS product establishes a TCP/IP Listener for each defined local gateway (port)
• If requested, outbound sessions are established with remote gateways
• The TMA TCP for IMS product puts up an outstanding write-to-operator with reply (WTOR) on the z/OS console by means of which operator commands can be entered

If any errors are detected during initialization, TMA TCP for IMS issues the appropriate error messages and initialization fails. If initialization fails, correct the indicated errors and restart TMA TCP for IMS.
