I am currently using a vendor application (see oracle-ds.xml file below) and it seems that we have poorly managed connections from our workflow managers (where the application runs) to the Database. We are having some serious performance issues and would appreciate any help on what parameters I can tweak to ensure performance is improved: <?xml version="1.0" encoding="UTF-8"?> <!-- ===================================================================== --> <!-- --> <!-- JBoss Server Configuration --> <!-- --> <!-- ===================================================================== --> <!-- $Id: oracle-ds-template.xml,v 1.6 2007/01/24 18:40:34 dave Exp $ --> <!-- ==================================================================== --> <!-- Datasource config for Oracle originally from Steven Coy --> <!-- ==================================================================== --> <local-tx-datasource> <jndi-name>OracleDS</jndi-name> <connection-url>jdbc:oracle:thin:@db01.dbt.pacs.com:1521:IMPAX</connection-url> <driver-class>oracle.jdbc.driver.OracleDriver</driver-class> <security-domain>OracleDSLogin</security-domain> <min-pool-size>20</min-pool-size> <max-pool-size>100</max-pool-size> <blocking-timeout-millis>5000</blocking-timeout-millis> <idle-timeout-minutes>1</idle-timeout-minutes> <!--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-connectio n-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> <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) --> <type-mapping>Oracle9i</type-mapping> </local-tx-datasource> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4026280#...
