Bug ID: 57460 Summary: [DB2]Connection broken after few hours but not removed from the pool? Product: Tomcat Modules Version: unspecified Hardware: Other OS: Linux Status: NEW Severity: normal Priority: P2 Component: jdbc-pool Assignee: dev@tomcat.apache.org Reporter: loic.rod...@gmail.com Hi, We encountered an error using tomcat.jdbc in acceptance. This pool is used by default on TomEE 1.6.0.2. Some application using DB2 had the issue after a night or at least some hours of inactivity. Some broken connections seems to be in pool. Changing the pool implementation to Common JDBC fix the problem. I am not sure it is very interesting to solve issue on DB2 but maybe... TomEE 1.6.0.2 use Tomcat 7.0.53 The driver used is DataDirect 5.1.3 Here is the pool configuration is: JdbcDriver com.merant.datadirect.jdbc.db2.DB2Driver JdbcUrl jdbc:datadirect:db2://ooooo:uuu;locationName=xxxx;packageCollection=JDBCV5R0 UserName XXXXXX Password XXXXXX JtaManaged true InitialSize 3 MaxActive 20 MinIdle 3 MaxIdle 10 TestOnBorrow true testOnReturn true testWhileIdle true numTestsPerEvictionRun 1 PoolPreparedStatements true MaxOpenPreparedStatements 128 ValidationQuery select current date from sysibm.sysdummy1 timeBetweenEvictionRunsMillis 100000 The stack trace is: Caused by: java.sql.SQLException: [DataDirect][DB2 JDBC Driver]Object has been closed. at com.ddtek.jdbc.db2base.ddcf.b(Unknown Source) at com.ddtek.jdbc.db2base.ddcf.a(Unknown Source) at com.ddtek.jdbc.db2base.ddce.b(Unknown Source) at com.ddtek.jdbc.db2base.ddce.a(Unknown Source) at com.ddtek.jdbc.db2base.BaseConnection.rollback(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.tomcat.jdbc.pool.ProxyConnection.invoke(ProxyConnection.java:126) at org.apache.tomcat.jdbc.pool.JdbcInterceptor.invoke(JdbcInterceptor.java:109) at org.apache.tomcat.jdbc.pool.interceptor.AbstractCreateStatementInterceptor.invoke(AbstractCreateStatementInterceptor.java:71) at org.apache.tomcat.jdbc.pool.interceptor.StatementCache.invoke(StatementCache.java:180) at org.apache.tomcat.jdbc.pool.JdbcInterceptor.invoke(JdbcInterceptor.java:109) at org.apache.tomcat.jdbc.pool.TrapException.invoke(TrapException.java:41) at org.apache.tomcat.jdbc.pool.JdbcInterceptor.invoke(JdbcInterceptor.java:109) at org.apache.tomcat.jdbc.pool.DisposableConnectionFacade.invoke(DisposableConnectionFacade.java:80) at com.sun.proxy.$Proxy71.rollback(Unknown Source) at org.apache.openejb.resource.jdbc.managed.local.LocalXAResource.rollback(LocalXAResource.java:158) ... 36 more -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
