Usage
With the ORA driver you specify the type of pooling you want
with the Pooling DBParm. The O90 and O10 database drivers that you
can use in PowerBuilder to connect to the 9.x and 10.x versions of
the Oracle DBMS support connection pooling with the DBParm parameter
CNNPool. For backward compatibility purposes, the CNNPool parameter
is also supported by the ORA driver. However, if you set the Pooling
parameter with the ORA driver, the CNNPool parameter is ignored.
If you are using connection or session pooling, the proxy
user name is the connection or session pooling creator (which you
can provide in the PoolCreator and PoolPwd DBParm parameters), and
the Transaction object’s LogID is ignored.
If you select session pooling, you can enter a value for the SessionHomogeneous
DBParm to authenticate all sessions in the pool with the user name
and password in effect when the session pool was created. No proxy session
can be created if pooling is set to homogeneous session mode.
