Specifies whether Oracle should maintain connections in a pool. An Oracle connection pool is a group of reusable physical connections spanning several sessions and managed by the Oracle Call Interface (OCI). The CNNPool DBParm is maintained in the ORA driver for backward compatibility only. It is ignored if you use the Pooling DBParm.
By default, connection pooling is not used.

If CnnPool='Yes',
the Oracle client creates a connection pool and can connect to Oracle9i,
and Oracle 10g Server. The pool contains physical
connections to Oracle Server and is managed by the OCI. The pool
persists until PowerBuilder terminates or OCI.dll is
unloaded.
PowerBuilder can connect to 10 different Oracle servers, as distinguished by service name, concurrently. There can be no more than 20 connections per pool. Each pool is created by the Oracle9i or later client and might also contain connections to Oracle8 and Oracle8i servers. Once a connection pool has been created, PowerBuilder maintains the physical connections until it terminates or OCI.DLL is unloaded.
To use connection pooling, enter values in the following fields of the Connection page in the Database Profile Setup dialog box:
Profile Name – Example
value: 08i-pool
Server – Provide the
full net service name created by Oracle Net. Example value: adcora8i.sybase.com
Login ID – Example
value: scott
Password
Connect as – Choose
an item from the drop-down menu. Example value: Normal
Make sure Use Connection Pool is selected.
