# AdvancedQueuingNotification.py

# This script demonstrates using advanced queuing notification. Once this
|

# script is running, use another session to enqueue a few messages to the
|
|
# "BOOKS" queue. This is most easily accomplished by running the
|
|
# AdvancedQueuing sample.

# This script requires cx_Oracle 6.4 and higher.
