Package State Retained After Session Released To Homogeneous Session Pool (Doc ID 260388.1)

Last updated on APRIL 09, 2020

Applies to:

Oracle Database - Enterprise Edition - Version and later
Information in this document applies to any platform.


We are using homogeneous session pooling __WITHOUT__ tagging. 

Testing demonstrates when a session is released to the pool unchanged. In other words, all outstanding transactions and package state 
(global variables in packages) are still visible when the session is reacquired. 

At this point the result is 1, not 0. 
A similar thing could be done for package variables. We have to make a call to 
rollback() to rollback any outstanding changes and a call to 
dbms_session.reset_package() to reset package state. 

The documentation states session pools yield stateless sessions. 
Testing indicates session pool instances are extremely stateful.
