Oracle RDBMS will disconnect any inactive clients after a certain
(server-side configurable) amount of time.

Subject: Used ConnectionManager instance could not obtain a connection,
retrying...
Date: Sat, 09 Apr 2005 20:30:42 +
hello I am using JDK1.4, OJB, and Oracle 9.2.0.2 on SuSE Linux 9.0
We ha dthis Web Application Running for few months... and there was NO
ACTIVITY on this web site in past 4-6 weeks... and now when I log on to
that I get following ERRORS...wonder why...
I am able to LOG in to SQLPLUS and query the database on Oracle Server but
when I log in to Web Application with Java front end... i get ERROR... I
checked my DB... it is UP RUNNING and the PORT 1521 is OPEN between App
Server and Oracle (as I said the web app was working great)
I tried restarting my Web, App and DB Server... but still get this
error...wonder why:
