File db2diag.log increases up to the AIX system limit

The file size of /home/dtdb23in/sqllib/db2dump/db2diag.log can grow up to the AIX system limit, while both Blueworx Voice Response and DB2 appear to still be running normally.

The problem is caused by high levels of errors being generated from the DB2 database manager because the diagnostic level is incorrectly set.

To check the current setting for the level of diagnostic error that is reported:

1. Login using the account that you use to run Blueworx Voice Response (the default is dtuser).
2. Type the following command to check the database manager configuration:

   db2 get dbm cfg | grep DIAGLEVEL

   If the current value for DIAGLEVEL is greater than 3, you should reset it back to the default level of 3 as follows:

1. Shutdown Blueworx Voice Response by running the command DT_shutdown.
2. Change the diagnostic level parameter by typing the following command:

   db2 update dbm cfg using DIAGLEVEL 3

3. Stop and restart DB2 to bring the changed parameter into use by typing:

   db2stop
   db2start 

4. Restart Blueworx Voice Response.
