I heard that the interface to view JMS queues is better in the newest (10g) OAS but I wonder if JMX is supported in this version.

Copied from OTN
Oracle is involved in JSR-77, which defines the way a Java 2 Platform, Enterprise Edition (J2EE) application server is managed via JMX. Oracle Application Server will expose a JMX Agent, and Oracle Enterprise Manager will provide a generic MBean browser that will allow customers to manage custom MBeans.

The OC4J 10.0.3 Developer Preview�available on Oracle Technology Network (OTN)�provides an early look at this support. If you install OC4J on your local machine, you can access its JMX console by entering http://localhost:8888/ adminoc4j in your browser

In fact, are there any real benefits for using JMX for management?

One of the nice effects of JMX and JSR-77 support is that you can use a variety of third-party tools to configure and monitor application servers.

Check out MC4J for an example:
http://mc4j.sourceforge.net/

Here's a screenshot of MC4J with an OC4J connection open:

Just noticed this page specifically about running MC4J with OC4J:

http://mc4j.sourceforge.net/usageOC4J.html

Note: It supports 10.0.3, but not 9.x.

Erin,


third-party tools to configure and monitor application servers

Why we need the third party to monitor OAS, instead of using its own tools?

When will they expose it? in OAS 10g?

We are using OC4J 10.0.4 for development. However it is quite different from the OAS we are currently using.

Thus, does the migration/upgrade effort being very large? If so, do you still recommended for upgrading from Oracle9i AS to Oracle10g AS?
