I'm using python 2.7.2 + Django 1.2.1 + djangopool + cx_Oracle 5.1.1 11g + Oracle instance client 11g + Oracle 10g on DB serrver
timeout :150 # connection timeout
And launch request to server in 2 threads
server creates 4 connections to DB server, but only 2 connections are in use.
In 150 seconds cx_Oracle starting releasing 2 unused connections and hangs up (approximately for 150 seconds) on
status = OCISessionRelease(connection->handle,
connection->environment->errorHandle, NULL, 0, mode);
5,1,1 10g with oracle instant client 10g all works correct. problem only with oracle instance client 11g
