Open Objects Percent

The percentage of open objects from the number configured.

The metadata caches reside in the kernel and server structures portion of Adaptive Server memory.

When Adaptive Server opens an object it needs to read information about it in the corresponding system tables: sysdatabases, sysindexes, and sysobjects.

The metadata cache for objects lets Adaptive Server access the information that describes it in the sysdatabases, sysindexes, or sysobjects row directly in its in-memory structure. This improves performance because Adaptive Server bypasses expensive calls that require disk access. It also reduces synchronization and spinlock contention when Adaptive Server has to retrieve database information at runtime.

You configure the number of open objects using sp_configure "number of open objects".
