Server Option support consists of several components on the IBM z/Series mainframe and the DirectConnect for z/OS Option platform, as the following diagram shows. On the z/OS Option platform, support is aided by information from LAN error report files, TDS and SNA trace files, and connectivity error log files. On the IBM z/Series mainframe, Server Option GW-Library and CICS aux traces, TCP/IP listener traces, and CICS debug tools help in troubleshooting.
