System components

The DB2 UDB Option for CICS support consists of several components on the IBM z/Series mainframe and the DirectConnect for z/OS Option platform, as Figure 8-1 shows. On a LAN 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, and CICS debug tools help in troubleshooting.

Figure 8-1 shows the Server Option and DirectConnect for z/OS Option support components in a CICS environment:
