Possible load-balancing issue in Teiid -------------------------------------- Key: TEIID-1453 URL: https://issues.jboss.org/browse/TEIID-1453 Project: Teiid Issue Type: Bug Affects Versions: 7.1.1 Reporter: Boris Belovic Assignee: Steven Hawkins Attachments: ConnectionWorker.java, LoadBalancingServlet.java, teiid-ds.xml I have 2 SOA-P servers clustered, both with Teiid installed. node1 has property org.teiid.sockets.maxCachedInstances set to 2 node2 has property org.teiid.sockets.maxCachedInstances set to 16 There is a web app deployed on node1 which starts consuming connections from Teiid datasource. When all connections from node1 are used, the app should get a connection from second node. But instead , I have got following exception: 16:06:59,341 ERROR [STDERR] org.jboss.util.NestedSQLException: Unable to get managed connection for TEIID-DS; - nested throwable: (javax.resource.ResourceException: Unable to get managed connection for TEIID-DS) 16:06:59,342 ERROR [STDERR] at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:95) 16:06:59,342 ERROR [STDERR] at org.jboss.soa.clustering.teiid.LoadBalancingServlet.getDatasourceConnection(Unknown Source) 16:06:59,342 ERROR [STDERR] at org.jboss.soa.clustering.teiid.LoadBalancingServlet.doGet(Unknown Source) 16:06:59,342 ERROR [STDERR] at javax.servlet.http.HttpServlet.service(HttpServlet.java:617) 16:06:59,342 ERROR [STDERR] at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) 16:06:59,342 ERROR [STDERR] at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) 16:06:59,342 ERROR [STDERR] at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) 16:06:59,342 ERROR [STDERR] at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) 16:06:59,342 ERROR [STDERR] at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) 16:06:59,342 ERROR [STDERR] at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) 16:06:59,342 ERROR [STDERR] at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:235) 16:06:59,342 ERROR [STDERR] at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) 16:06:59,342 ERROR [STDERR] at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:183) 16:06:59,342 ERROR [STDERR] at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:95) 16:06:59,342 ERROR [STDERR] at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.process(SecurityContextEstablishmentValve.java:126) 16:06:59,342 ERROR [STDERR] at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.invoke(SecurityContextEstablishmentValve.java:70) 16:06:59,342 ERROR [STDERR] at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) 16:06:59,342 ERROR [STDERR] at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) 16:06:59,342 ERROR [STDERR] at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:158) 16:06:59,342 ERROR [STDERR] at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) 16:06:59,342 ERROR [STDERR] at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:330) 16:06:59,342 ERROR [STDERR] at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:829) 16:06:59,342 ERROR [STDERR] at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:598) 16:06:59,342 ERROR [STDERR] at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:451) 16:06:59,342 ERROR [STDERR] at java.lang.Thread.run(Thread.java:619) 16:06:59,342 ERROR [STDERR] Caused by: javax.resource.ResourceException: Unable to get managed connection for TEIID-DS 16:06:59,342 ERROR [STDERR] at org.jboss.resource.connectionmanager.BaseConnectionManager2.getManagedConnection(BaseConnectionManager2.java:441) 16:06:59,342 ERROR [STDERR] at org.jboss.resource.connectionmanager.TxConnectionManager.getManagedConnection(TxConnectionManager.java:424) 16:06:59,343 ERROR [STDERR] at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnectionManager2.java:496) 16:06:59,343 ERROR [STDERR] at org.jboss.resource.connectionmanager.BaseConnectionManager2$ConnectionManagerProxy.allocateConnection(BaseConnectionManager2.java:941) 16:06:59,343 ERROR [STDERR] at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:89) 16:06:59,343 ERROR [STDERR] ... 24 more 16:06:59,343 ERROR [STDERR] Caused by: javax.resource.ResourceException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] ) 16:06:59,343 ERROR [STDERR] at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.getConnection(InternalManagedConnectionPool.java:311) 16:06:59,343 ERROR [STDERR] at org.jboss.resource.connectionmanager.JBossManagedConnectionPool$BasePool.getConnection(JBossManagedConnectionPool.java:690) 16:06:59,343 ERROR [STDERR] at org.jboss.resource.connectionmanager.BaseConnectionManager2.getManagedConnection(BaseConnectionManager2.java:404) 16:06:59,343 ERROR [STDERR] ... 28 more
