Where to start troubleshooting

At the client, the DirectConnect for z/OS Option workstation, and mainframe levels, check components systematically to locate the problem. Depending on your setup, you may want to check for problems in this sequence:

1. Connectivity

2. Client application

3. Client LAN

4. Client network setup

5. Major outage

6. DirectConnect for z/OS Option workstation

7. Connection from the client to the DirectConnect for z/OS Option workstation

8. Connection from the DirectConnect for z/OS Option workstation to the mainframe

9. Configuration between the transaction processor and the Server Option, or OmniSQL Access Module for DB2 for IMS TM and MVS

For any of these problems, the appropriate system administrator should use normal troubleshooting procedures. For example:

• Record specific information on the error message(s), including:

  • Error message number

  • Associated SNA sense codes or SNA Services error codes

  • Time the error occurred

  • The client or user affected

• Perform the recommended action.

• Continue the process until the problem is resolved.
