5250 problem isolation
Use this information to isolate problems with your 5250 emulator.
Communications
Use the cwbping program to verify the connection between the Linux® workstations and the iSeries™ server, and to verify the host servers are started.
Tracing and Logging
Once you verify your connection to the server, there see the following trace files for problem isolation:
- History log. The history log shows high-level communication, security and data conversion error messages. The History log is activated using the cwbtrc program.
- Detail trace. The detail trace shows low-level driver information and is intended for use in reporting problems to IBM®. Detail trace is activated using the cwbtrc program.
- Service information collection tool. The service information collection tool is intended for use in reporting problems to IBM. The service information collection tool is activated using the cwbmedic program.
- ibm5250. Adding the -debug flag to the ibm5250 command line will show detailed information for the emulator.
- ibm5250. Adding the -trace flag to the ibm5250 command line will trace the telnet activity between the emulator and host OS/400®
