tests. Although the two are aliases of one another, it makes sense to be consistent and to use the one that the DB API prefers as well.

# DRCP.py
|
|
# This script demonstrates the use of Database Resident Connection Pooling
|
|
# (DRCP) which provides a connection pool in the database server, thereby
|
|
# reducing the cost of creating and tearing down client connections. The pool
|
|
# can be started and stopped in the database by issuing the following commands
|
|
# in SQL*Plus:
|
|
#
|
|
# exec dbms_connection_pool.start_pool()
|
|
# exec dbms_connection_pool.stop_pool()
|
|
#
|
|
# Statistics regarding the pool can be acquired from the following query:
|
|
#
|
|
# select * from v$cpool_cc_stats;
|
|
#
|
|
# There is no difference in how a connection is used once it has been
|
|
# established.
|
|
#
|
|
# This script requires cx_Oracle 5.0 and higher.
