open objects Option
This option is still present in sp_configure, although its functionality has been disabled in Microsoft SQL Server. (The setting has no effect.) In SQL Server, the number of open database objects is managed dynamically and is limited only by the available memory. The open objects option available in sp_configure for backward compatibility with existing scripts.
This feature will be removed in a future version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible.
