System administrators at the client, DirectConnect server, and mainframe must check components systematically to locate the source of a problem. Check for problems in this sequence:
Major outage, such as a CICS crash or power outage
Client application
Client LAN
Client network setup
DirectConnect server
Connection from the client application to the DirectConnect server
Connection from the DirectConnect server to the mainframe
Configuration between the transaction processor and the Server Option or the DB2 UDB Option for CICS
For any of these problems, the appropriate system administrator should:
Record specific error message information, including:
Error message number
Associated SNA sense codes, SNA Services error codes, or TCP/IP error codes
The time the error occurred
The client or user affected
See the appropriate documentation, as needed. For example, if you need information about the DB2 UDB Option for CICS errors, see Appendix A, “Error Messages.”
Perform the recommended action.
Continue the process until the problem is resolved.
