How do I track if weblogic needs restart after any datasource or new service changes? Assuming you do not notice the notification displayed by weblogic...

The WLST function isRestartRequired() determines if a change you made to an MBean attribute requires you to re-start servers in your domain. Take a look at the Oracle documentation.

I have added Hornetq user using add-uesr.sh script.
I want to write a script to verify hornetq username and password entered by someone is correct or not (before configuring any other components like JMS queues etc).
Does JBOSS CLI provide a way to check the validity of authentication details?
Thank you!
You will not be able to use the JBoss CLI.
I suggest using a Hornteq JMS Client, just extend an example program and pass in username and password via command line paramters or property files. You could also check the correct queues and topics are available to the given user. You can also use the JBoss CLI in Java to check a message is delivered to a queue or topic etc. Make sure your program uses the correct exit code for success or failure.
Any good suggestion for Monitoring JBOSS 7 in Production ? I would also like to configure alerts based on certain condition. Of course , It has to be Open source.
Thanks.
You can use standard JConsole that comes with JBoss dependencies added. It's used to monitor your servers state and mbeans, it's very useful.
To test it on localhost start your server and then run the JConsole from your server/bin directory and select JBoss in the Local process selection.
To use it on "remote" server, start your server on "REMOTE_HOST" and then run JConsole from an JBoss/bin directory and connect with the followin string
service:jmx:jmx-remoting://REMOTE_HOST_NAME:9999 (or the port you use) and enter the username and password.
Secondly, for more detailed info of objects creation, memory leaks, CPU% (profiling) there is another one as:
http://jbossprofiler.jboss.org/
You can try to use free open source APM like scouter.
It shows very useful realtime performance information of every request.
And also you can set a threshold of resources and can make plugin for alerting to external.

JBoss7 need to set module option.

I'm deploying an ASP.NET MVC 2 application using Apache / mod_mono / MONO (2.8.1) that uses the built in ASP.NET authentication framework.
When I restart Apache, or use the mod_mono control panel to restart the mono server process, users are logged out. I don't want this occurring.
I'm using custom Profile / Membership / Role providers (that are backed by a Redis database), and these currently have a bare minimum implementation. I can not see where my problem fits in here however, but am I missing something obvious?
I notice that the .MONOAUTH cookie changes value when a user logs back in, so I guess there is some persistence that needs to happen that is not happening.
Any solutions or pointers to the relevant documentation would be great!
NOTE: I'm not sure if the information below differs when you're using a Membership Provider -- it may be that session state is persisted by the Membership Provider itself.
It's likely that you're using "in-process" session state storage. This means that whenever you restart the web server process, you're clearing out all the session information stored in the web server process's memory space.
To avoid wiping out session information, you can move to using an out-of-process session state server, either running as an in-memory service (see below for the Mono version) or on SQL Server. Otherwise there are also a number of unofficial custom session store providers that use alternative storage mechanisms (e.g. MongoDB etc.)
I found what you may want, which is this Mono ASP.NET Session State Server: http://manpages.ubuntu.com/manpages/gutsy/man1/asp-state2.1.html
As a first step, take a look in your web.config at the system.web -> sessionState property. If it's set to mode="InProc" then there's your problem. It should look more like:
<sessionState
mode="StateServer"
stateConnectionString="tcpip=server:port"
stateNetworkTimeout="number of seconds"/>
Solution: set the validationKey and decryptionKey manually:
<machineKey validationKey="blahblah" decryptionKey="blahblah" />
I think this is probably a bug in mono that these take on different values over server resets when auto-generated (which is the default).
I am doing an automatic upgrade through Azure portal. While it is upgrading 1st instance, if I try to access my site through http://xyz.cloudapp.net it doesn't open.
IMO when 1st instance is upgrading, the request should be served from the 2nd instance, but I think this is not happening, that's why I see site unavailable message on my browser.
Is it something which I need to do/configure before I do an upgrade?
Your understanding matches mine. I would open a support ticket (http://windowsazure.com/support) to get to the bottom of it.
You want to handle the RoleEnvironmentChanging event properly (i.e. don't set the e.Cancel to true if you don't need to reboot)

I have deployed a REST service on an external server (IIS7). When I start the service from VS on the Dev server it works fine. But on the server i get:
Request Error, The server encountered an error processing the request. Please see the service help page for constructing valid requests to the service.
How do I get more details on this error? I have looked in the log files directory that is configured under Logging feature for this web site in IIS Manager, but there are no files at all for this site it seems.
You should look in the Windows Event Log using the Event Viewer application (eventvwr.exe). Output to the IIS log files may be buffered so their contents may be updated after a restart, or when IIS is set to do it. Restarting IIS is a surefire way to force this.
Here is a blog post on how to do this.
I'm aware of 3 ways to get nicer errors:
Set UseVerboseErrors in InitializeService method. However, this won't give you anything if your error occurs before InitializeService is called (which happens).
Set IncludeExceptionDetailInFaults to true using an attribute before your service class.
Set IncludeExceptionDetailInFaults to true using web.config.
