Use More Buffers

CA Datacom Version 14.0 delivers an enhanced buffer recognition hashing algorithm. This enhanced technique significantly reduces the amount of CPU needed for managing large amounts of buffers. This improvement increases the value of having data blocks in memory as opposed to doing physical I/O.

Business Value

Specifying additional buffers does not significantly increase the CPU processing needed for managing the buffers, but having additional buffers can reduce physical I/O which also reduces CPU consumption.

Additional Considerations

The CA Datacom/DB Database and System Administration Guide contains a chapter on optimizing CA Datacom/DB performance. This chapter discusses various techniques on how to monitor and tune the various CA Datacom/DB buffer pools. Review this information and other resources (such as the CA Datacom webcasts) to understand how to monitor and tune buffer specifications.
