Documentation references for problem diagnosis

This topic contains the information and documentation references required to gather and decode diagnostic information about the IMS™ TCP/IP Services socket interface system.

The two main tools used for problem diagnosis are the IP packet trace facility and the NETSTAT utility. The use of these tools is explained in following sections and example statements and commands are provided. An explanation of how to interpret the output from each of these tools is also provided.

For TCP/IP or IMS-specific tracing, reference is made to the appropriate diagnosis documentation.

Two cross-reference sections, which list all the types of return codes and error messages that can be issued from the IMS TCP/IP Services socket interface system, are provided at the end of this section. For each type of return code and error message, a reference is made to existing documentation that provides a complete description.
