Adrain , while making the changes related to JBAS-4662 in the trunk I noticed that 1) The ha behavior in the xa-datasource configuration is not working as expected . I tested the following configuration <xa-datasource> | | <jndi-name>XAOracleDS1</jndi-name> | <reauthentication-mechanism>org.jboss.resource.adapter.jdbc.vendor.DummyReauthenticationMechanism</reauthentication-mechanism> | <user-name>scott</user-name> | <password>tiger</password> | <track-connection-by-tx/> | <isSameRM-override-value>false</isSameRM-override-value> | <connection-property name="connectionProperties">key=Value</connection-property> | <xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class> | <xa-datasource-property name="URL">jdbc:oracle:thin:@localhost:1527|jdbc:oracle:thin:@localhost:1523|jdbc:oracle:thin:@localhost:1524|jdbc:oracle:thin:@localhost:1521</xa-datasource-property> | <url-delimiter>|</url-delimiter> | <url-property>URL</url-property> | <!-- xa-datasource-property name="User">scott</xa-datasource-property --> | <!-- xa-datasource-property name="Password">tiger</xa-datasource-property --> | <!-- xa-datasource-property name="ConnectionProperties">XATransLoose=true</xa-datasource-property --> | <min-pool-size>1</min-pool-size> | <max-pool-size>5</max-pool-size> | <prefill>true</prefill> | <!-- Uses the pingDatabase method to check a connection is still valid before handing it out from the pool --> | <!--valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name--> | <!-- Checks the Oracle error codes and messages for fatal errors --> | <!-- exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name --> | <!-- Oracles XA datasource cannot reuse a connection outside a transaction once enlisted in a global transaction and vice-versa --> | <no-tx-separate-pools/> | <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) --> | <metadata> | <type-mapping>Oracle9i</type-mapping> | </metadata> | | </xa-datasource> And I get this exception 08:04:40,585 INFO [ConnectionFactoryBindingService] Unbound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=XAOracleDS1' from JNDI name 'java:XAOracleDS1' | 08:04:48,109 WARN [JBossManagedConnectionPool] Unable to fill pool | org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (java.sql.SQLException: Io exception: Invalid connection string format, a valid format is: "host:port:sid" ) | at org.jboss.resource.adapter.jdbc.xa.XAManagedConnectionFactory.getXAManagedConnection(XAManagedConnectionFactory.java:452) | at org.jboss.resource.adapter.jdbc.xa.XAManagedConnectionFactory.createManagedConnection(XAManagedConnectionFactory.java:405) | at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.createConnectionEventListener(InternalManagedConnectionPool.java:611) | at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.fillToMin(InternalManagedConnectionPool.java:527) | at org.jboss.resource.connectionmanager.PoolFiller.run(PoolFiller.java:74) | at java.lang.Thread.run(Thread.java:595) | Caused by: java.sql.SQLException: Io exception: Invalid connection string format, a valid format is: "host:port:sid" | at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112) | at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:146) | at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:255) | at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:387) | at oracle.jdbc.driver.PhysicalConnection.<init>(PhysicalConnection.java:414) | at oracle.jdbc.driver.T4CConnection.<init>(T4CConnection.java:165) | at oracle.jdbc.driver.T4CDriverExtension.getConnection(T4CDriverExtension.java:35) | at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:801) | at oracle.jdbc.pool.OracleDataSource.getPhysicalConnection(OracleDataSource.java:297) | at oracle.jdbc.xa.client.OracleXADataSource.getPooledConnection(OracleXADataSource.java:456) | at oracle.jdbc.xa.client.OracleXADataSource.getXAConnection(OracleXADataSource.java:143) | at oracle.jdbc.xa.client.OracleXADataSource.getXAConnection(OracleXADataSource.java:129) | at org.jboss.resource.adapter.jdbc.xa.XAManagedConnectionFactory.getXAManagedConnection(XAManagedConnectionFactory.java:444) | ... 5 more | 08:04:49,844 INFO [ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=XAOracleDS1' to JNDI name 'java:XAOracleDS1' In the above configuration the last URL is valid so it should have been considered but the deployment does not consider the chain of URL's seperated by url delimiter . 2) The similar changes in the local-tx-datasource works as expected . I have noticed that this from the logs 2008-04-23 08:04:43,856 DEBUG [org.jboss.resource.adapter.jdbc.xa.XAManagedConnectionFactory] (HDScanner) inside the initSelectornull | which appears to be coming from private void initSelector() throws JBossResourceException | { | log.debug("inside the initSelector"+urlProperty); | if(urlProperty != null && urlProperty.length() > 0) | { | String urlsStr = xaProps.getProperty(urlProperty); | if(urlsStr != null && urlsStr.trim().length() > 0 && urlDelimiter != null && urlDelimiter.trim().length() > 0) | { | List xaDataList = new ArrayList(); I also confirmed that the JBAS-4662 changes are not causing this issue , will have to see how the Deployment builder populate the values from the MetaData into the MBeanService through the ServiceMetaData .
