PL/SQL Performance Tips

Oracle Tips by Burleson Consulting

 

Brian Carr has offered some valuable information that users can use if you have a popular PL/SQL package:
 

Pinning popular packages in shared memory:

 
You can pin the popular packages in shared memory pool by using DBMS_SHARED_POOL. When you pin a package it is not aged out by the least
recently used (LRU) algorithm that Oracle uses. It will remain in memory.

For declared (but unused variables) in your PL/SQL code:


PL/SQL waits to allocate memory until you assign the variable, then only
allocates as much storage as needed.  So no need to worry about consuming memory.

Identifying bottlenecks:


PL/SQL provides a Profiler API to identify run-time behavior and to help you
find performance bottlenecks.  It's the DBMS_PROFILER PL/SQL Package. 

 

You can read more about this package at:
