Providing more BI buffers
You can increase the number of before-image buffers in the before-image buffer pool with the Before-image Buffers (-bibufs) startup parameter. Increasing the number of buffers increases the availability of empty buffers to client and server processes. In general, initially set this parameter to 20. Increase it if there are any empty buffer waits in the PROMON Activity screen or in the R&D BI Log Activity screen.
