RE: [Zope-DB] Closing idle DCoracle2 Connections?
Ok, that's a bit much for my question I guess... I gather from all your mails that I can not "close" a database connection periodically or on event from Zope (Script or whatever)? Any hands-down clues what I can do to prevent db-conns from ideling around? /Carsten >-Original Message- >From: Dieter Maurer [mailto:[EMAIL PROTECTED] >Sent: Saturday, October 22, 2005 8:07 PM >To: Matthew T.

[Zope-DB] Closing idle DCoracle2 Connections?
Hello everyone, As we start to use our zope-Ora connection more frequently our database administrator complains that he sees a lot of idle conections. I know theres "connection.close()" in DCOra2 but does anyone know of a way to autmatically close a DCOra within Zope when idle soandso long? Or any other way to adress such a problem? I know that I wouldn't want the connection being closed from Oracles side as I have read in the mailinglist that DCOracle would still think the connection is open and generate an error. Our Specs atm: Oracle version strings: * TNS for Solaris: : 9.2.0.5.0 (Production) * PL/SQL : 9.2.0.5.0 (Production) * NLSRTL : 9.2.0.5.0 (Production) * Oracle9i Enterprise Edition : 9.2.0.5.0 (Production) * DCOracle2: (cvs release) -- DCOracle2 1.103 (dco2: 1.137 -DORACLE8i -DORACLE9i -DUSEOBJECT -Dlinux -DNATIVENUMERIC=1 -D_REENTRANT ) Thanks in Advance /Carsten Carsten Germer Deutsches Elektronen Synchrotron (Web-Office, IT) phone: +49-40-8998-1661Notkestr. 85 web: http://wof.desy.de22607 Hamburg e-mail: [EMAIL PROTECTED] Germany ___ Zope-DB mailing list Zope-DB@zope.org http://mail.zope.org/mailman/listinfo/zope-db
RE: [Zope-DB] DCOracle2 1.3.beta common Problem, where to get latest build?
Gah! Think simple, Carsten... Although I tested everything the environment variables didn't find their way into that specific instance. Fixed that and works now. Question: Should I get the latest DCO from the cvs anyway or should I better stay with 1.3b? Cheers /Carsten >-Original Message- >From: Matthew T.

[Zope-DB] DCOracle2 1.3.beta common Problem, where to get latest build?
Hi everyone, Oracle 9i works fine with SQLPlus on my Suse 8.2 machine with Zope 2.7.5-final. I downloaded and installed DCOracle 1.3 beta from http://www.zope.org/Members/matt/dco2. A few problems with compiling where resolved easily. Now I get that infamous error ... Module Products.DCOracle2.DCOracle2.DCOracle2, line 185, in connect BadRequest: Invalid connection string: xxx/[EMAIL PROTECTED] I read up on mailing lists and found that someone says that there's a newer version out "Also, the latest cvs build of dco2.so is 1.137 or so, so you're running about 8 patches behind at your current code base." Where can I get a more recent version of DCOacle 2? Or has anyone any other hint on how to resolve this?
