I look into WAS5 docs about JNDI Naming service. I found for pure Java client to access EJB, it has to know if the EJB is deployed on single server or in a cluster.
And dumpNameSpace.bat only dumps local Node JNDI tree!
Come on, this is totally bad design. Why JNDI has to be seperated at Cell/Node level, and why application must be aware of this?
To me, one JNDI tree per domain is just right, each NodeAgent backs up each other as JNDI name service provider, and DeploymentManager serves as the master copy.
What's your opinion? I want to hear more opinions on this and head for WebSphere FRD for change.

Probably manul rewrite these files. IBM doesn't have util to cover it.

From my previous investigation, even MQ doens't support that transparent failover feature you need.
It is true also in WLS 7.1/8.0.

I bet it will be much less efficient, especially under heavy load. For a customer demo, it is just fine.
You'd open a PMR against IBM for this issue, or send email to the As/400 Toolkit developer(you may find their email address in the newsgroup).

Add it as an property to the datasource.

Since WAS 4.0, there is already an embedded HTTPServer with each AppServer.
The external webserver uses HTTP(no longer OSE) to reroute requests to AppServer(servlet Engine).
Also this embedded HTTPServer serves for webservice requests.
IBM still recommend having an external webserver for performance/security/scalability for production deployment.

It is available in WAS4.0, you can search it in the InfoCenter for WAS4.0. Search for key word "hot deployment", basically you have to enable it in the EAR level, and redeploy EJB means restart the whole EAR.

Maybe there is also max appls/connections setting at the instance level?
And you must have defined 6 datasource inside WAS, each has maximum connections over 10?(default is 10)

Check your DD, maybe you foget to associate the DS name with the real global DS name?

You must have this class in some other Jars. Or try remove ear, and reinstall it with your new version.

Look into your web application deployment descriptor IBM extension part, you have to turn on autoreload there. The default setting turns it off, you must specify a reloadinterval also.

Yeah, you need dl efix to resolve the Merant license issue.
See IBM support site for more information.
