About Spooling SQL in the Siebel Application
Using spooling with the Siebel application can be useful for several reasons:
It allows you to identify the SQL statement being executed when an SQL error code is returned.
It can help you in assessing the time taken by the various SQL statements when you encounter performance issues.
When data appears to be missing from a view, you can identify the SQL used to retrieve that data.
You can then run the SQL manually, either from the midtier computer, for example using the DB2 Command Center, or on the DB2 for z/OS host, for example using tools such as SPUFI, to see what data is being returned.
To minimize the amount of SQL tracing produced, and, therefore, the size of the log files, limit the tests to the minimum number of screen changes needed to allow the issue to be reproduced. If possible, spool SQL on a Developer Web Client as you have more control over the testing which makes it easier to minimize the amount of SQL traced.
