DB2 Connect User's Guide
Problem determination includes narrowing the scope of
the problem and investigating the possible causes. The proper starting
point is to gather the relevant information and determine what you know, what
data has not been gathered, and what paths you can eliminate. At a
minimum answer the following questions.
- Has the initial connection been successful?
- Is the hardware functioning properly?
- Are the communication paths operational?
- Have there been any communication network changes that would make previous
directory entries invalid?
- Has the database been started?
- Is the communication breakdown between client and DB2 Connect workstation,
DB2 Connect workstation and host or AS/400 database server, all clients or one
client?
- What can you determine by the content of the message and the tokens
returned in the message?
- Will using diagnostic tools provide any assistance at this time?
- Are other machines performing similar tasks working correctly?
- If this is a remote task, is it successful if performed locally?
