30 Oracle SQL Internals Handbook SQL Tuning Using dbms_stats CHAPTER 4 Query Tuning Using DBMS_STATS Introduction Increasingly enterprises are purchasing their mission-critical applications, whether these use Oracle or other data management software. Typically the licensing and support agreements for such applications seek to prevent the customer from reverse engineering or modifying the application in any way. Although such restrictions may be extremely sensible from a supplier's point of view, they can prevent an individual site from making changes that would result in valuable performance benefits.
Finally, it gives you an option for using the new cursor_sharing parameter without paying the penalty of losing optimum execution paths. There are a few issues to work around in Oracle 8 (largely eliminated in Oracle 9), but in general it is very easy to take advantage of this feature; and this article describes some of the things you can do. Background / Overview To demonstrate how to make best use of stored outlines, we will start with a stored procedure with untouchable source code that (in theory) is running some extremely inefficient SQL.
Although such restrictions may be extremely sensible from a supplier's point of view, they can prevent an individual site from making changes that would result in valuable performance benefits. This paper describes the work performed to overcome a specific performance problem in a purchased application without having to resort to the obvious (but impossible) solution of modifying the application code. Test Environment The experiments conducted during the preparation of this paper were performed on the author's laptop, a Compaq Armada M700 with 448 Mb of memory and a single 20 Gb hard disk partitioned into a FAT device for the operating system and an NTFS device for both the Oracle installation and the database files.
