Are there any error messages or return codes that explain the problem?
The problem might produce the following types of error message or return codes:
- CSQ messages and reason codes
- WebSphere MQ for z/OS error messages have the prefix CSQ; if you receive any messages with this prefix (for example, in the console log, or the CICS log), look in the WebSphere MQ for z/OS Messages and Codes manual for an explanation.
- Other messages
- For messages with a different prefix, look in the appropriate messages and codes manual for a suggested course of action that might help you resolve the problem. Table 15 lists possible message prefixes and appropriate manuals.
- Unusual messages
- Any unusual messages associated with the startup of WebSphere MQ for z/OS, or issued while the system was running before the error occurred, might indicate some system problem that prevented your application from running successfully.
- Application MQI return codes
- If your application gets a return code indicating that an MQI call has failed, see the WebSphere MQ Application Programming Reference manual for a description of that return code.
