Procedure Cache Size

The amount of memory allocated to the procedure cache.

The procedure cache is used by the ASE while running stored procedures. If the server finds a copy of a procedure already in the cache, it does not need to read it from the disk, thus saving slower disk I/O.

Space in the procedure cache is also used by the ASE to compile queries while creating stored procedures.

Since the optimum value for procedure cache size differs from application to application, resetting it may improve Adaptive Server's performance. For example, if you run many different procedures or ad hoc queries, your application uses the procedure cache more heavily, so you may want to increase this value.

Note: If the configured size of the procedure cache is too small, the Adaptive Server's performance will be greatly impacted.
