Thanks for everyone who responded. I'll enable sqlnet.expire_time, that should handle the dead connections. I checked out SQL Developer, it is a nice query tool but not intuitive enough for some one who doesn't know SQL. Right now in MS Access the business users drag/drop columns to build a query, anything similar in nature would be easier for me to sell. Am I just being paranoid or Access is capable of handling large queries (upto ~200K records)? -Upendra > From: Freek.DHooge@xxxxxxxxx > To: mark.powell2@xxxxxx; oracle-l@xxxxxxxxxxxxx > Date: Tue, 17 Aug 2010 16:40:48 +0200 > Subject: RE: Tool recommendation > > Hi, > > Another solution (depending if the session is really dead) could be to enable > dcd (dead client detection, sqlnet.expire_time) in de sqlnet.ora file on de > server. > > http://download.oracle.com/docs/cd/B19306_01/network.102/b14213/sqlnet.htm#sthref475 > > > > regards, > > Freek D'Hooge > Uptime > Oracle Database Administrator > email: freek.dhooge@xxxxxxxxx > tel +32(0)3 451 23 82 > http://www.uptime.be > disclaimer: www.uptime.be/disclaimer > -- > From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On > Behalf Of Powell, Mark > Sent: dinsdag 17 augustus 2010 16:09 > To: oracle-l@xxxxxxxxxxxxx > Subject: RE: Tool recommendation > > Why not write a dead session detection script that looks for and clears these > sessions out and schedule it to run every X minutes? > > Or maybe create an on-demand script that is launched via a web application or > by the operators. > -- > //www.freelists.org/webpage/oracle-l > >
