Link to official Java networking properties page: http://docs.oracle.com/javase/7/docs/technotes/guides/net/properties.html http.keepAlive (default: true) Indicates if keep alive (persistent) connections should be supported. Persistent connections improve performance by allowing the underlying socket connection be reused for multiple http requests. The default is true and thus persistent connections will be used with http 1.1 servers. Set to 'false' to disable the use of persistent connections. http.maxConnections (default: 5) If HTTP keep-alive is enabled, this value is the number of idle connections that will be simultaneously kept alive, per-destination.

When you start Tomcat for the first time, you may get the "port 8080 is already in use" error. Indeed, port 8080 is commonly used by a lot of development servers by default (Oracle XE for another example). Luckily, it's quite easy to ask Tomcat to use a different port. I use port 8086, which is a natural next step and superior to 8080. Simply edit $CATALINA_BASE/conf/server.xml and change 8080 to 8086:
<!-- A "Connector" represents an endpoint by w...If you have not configured Tomcat 6 for multiple instances by setting a CATALINA_BASE directory, then $CATALINA_BASE will be set to the value of $CATALINA_HOME , the directory into which you have installed Tomcat 6.

The text source of the stored objects (including stored procedures) are made available in Oracle by three views: USER_SOURCE describes the text source of the stored objects owned by the current user. This view does not display the OWNER column. ALL_SOURCE describes the text source of the stored objects accessible to the current user. DBA_SOURCE describes the text source of all stored objects in the database. These are the columns: Column Name Description OWNER Owner of the object NAME Name of the object TYPE Type of object: FUNCTION, JAVA SOURCE, PACKAGE, PACKAGE BODY, PROCEDURE, TRIGGER, TYPE, TYPE BODY LINE Line number of this line of source TEXT Text source of the stored object If you want to search for a certain keyword in the source,...

This procedure works for Oracle application server 10.1.3.1, SOA suite. But should be applicable for standalone OC4J or JDeveloper installations with minor modifications. $ORACLE_HOME is the home directory for Oracle app server. $JDEV_HOME is the home directory for JDeveloper. 1. Change directory to $ORACLE_HOME/j2ee , mkdir lib 2. Copy xmlparserv2.jar from $JDEV_HOME to $ORACLE_HOME/j2ee/lib . 3. Copy ocj.jar and jdev_remote.jar from $JDEV_HOME/jdev/lib to $ORACLE_HOME/j2ee/home/lib . 4. Edit global-web-application.xml under your OC4J instance's config directory. Change the development attribute to true .
<orion-web-app xmlns:xsi="http://www.w3.org/...5. Add the following to the servlet section of global-web-application.xml :

If you use quartz or the plain old java.util.Timer class to schedule jobs in an OC4J container, you need to enable the -userThreads switch with the OC4J container. This is the relevant section in $ORACLE_HOME/opmn/conf/opmn.xml :
<process-type id="INST1" module-id="OC4J" status="...Or, you can add it through the Oracle em console. Go to the OC4J container, click "Administration" tab, then "Server Properties". Add "-userThreads" to "Start-parameters: OC4J Options". Debu Panda has written a good article on using quartz in the Oracle environment: Using Quartz Enterprise Scheduler in J2EE

First create a resource provider for Oracle AQ in orion-application.xml:
<?xml version = '1.0' encoding = 'windows-1252...Then, hook up the EJB to the queue in orion-ejb-jar.xml:
<?xml version = '1.0' encoding = 'windows-1252...Make sure the resource names ('rsname') match among the xml files. Full information is available from the Oracle document titled "Oracle Containers for J2EE Enterprise JavaBeans Developer's Guide 10g (10.1.3.1.0)". Look at Appendix A.
