Hi, Here is my connector, Oracle9i yet...
May be i have to set the jdbc-level at 3.0 ? Referring to this article, it seems that it is a hard to resolve trouble. http://www.orafaq.com/node/758 Except looking into code, how to check "real" cursors leak (if they are)? Regards <jdbc-connection-descriptor jcd-alias="default" default-connection="true" platform="Oracle9i" jdbc-level="2.0" driver="oracle.jdbc.driver.OracleDriver" protocol="jdbc" subprotocol="oracle" dbalias="thin:@XXXX:1521:ZZZZZ" username="uuuuuuuuu" password="pppppppp" batch-mode="false" useAutoCommit="1" ignoreAutoCommitExceptions="false" > ---------- Forwarded message ---------- From: Danilo Tommasina <[EMAIL PROTECTED]> Date: Oct 9, 2006 6:08 PM Subject: Re: Monitoring DB cursor leaks To: OJB Users List <ojb-user@db.apache.org> Hi, we were having that problem too, long time ago. You should use the 'Oracle9i' Platform setting in your jdbc-connection-descriptor instead of the Oracle 'Platform', that should fix the problem. IIRC the 'Oracle' Platform does a caching of PreparedStatements, however the Oracle Driver has its own PreparedStatements cache, having this double caching causes too many cursors to stay open. The Oracle9i Platform should not make use of the local PreparedStatements cache. Furhtermore the 'Oracle9i' offers better performance and correct handling for BLOBs > 4kB, for 9i or later Oracle versions. Good luck cheers Danilo Bruno CROS wrote:
Hi all, Experiencing some MAX OPEN CURSOR oracle errors (ORA -01000) , i'm
looking
for the cursors leaks ( unclosed ResultSet it seems) in code. I guess that broker queries well close the result set. So when report queries results iteration are closed ? on HasNext()==false ? Is it possible to check open cursors when releasing connections ? and by the way, close them if needed ? Note : MAX_OPEN_CURSOR Oracle parameter is actually set at 500 by connection ( and 1000 sooner ) Oracle 10, OJB 1.0.4 with some litle updates Regards.
