Null argument for startup classes when managered server starts

Hi Everyone,
We have a Weblogic 10.3.5 clustering environment. the environment seems to work fine. I am able to have the servers (both Admin and Managed) and deployed applications running without any problems. However, I just notice that, every time when I start the Managered servers, I got the following information in the system log. It appears that they are start-up classes, but with null argument. Are they normal or not?
Thanks in advance,
John

Hi John,
This is Ok. Those are just info messages. Thery are not warnings or errors, so nothing to worry about.
If the classes are invoked with null arguments and no exception is thrown, then is means that the class is able to have a null argument, so nothing to worry about again.

Initialising class when J2EE server starts

Hi,
I am facing a problem. I wish to instantiate a class when the J2EE/ tomcat server starts. This is similar to the property set in weblogic as
weblogic.system.startupClass.startup = <name of ur startup class>
Here we can specifiy the class to be instantiated during startup of server.
Can i do something similar in tomcat/ j2ee server?
I do not wish to use a servlet since my webapplication contains jsps and other supporting classes and my own apis.
Thank you in adv.
...supriya.

if you use ServletContext Listeners you should be ready as far as web app is concerned. Most servers I believe offer JMX integration so that you can listen for server startups. : )

Startup Class in WebLogic server 6.1

I Have a Java application as startup class in Weblogic server 6.1 . I need to stop
the application without restarting the Weblogi server (The startup class should

Even if it is EJB-only, adding .war with startup logic will be more convinient
than startup classes.

How to disable autostart (application) when managed server restart ?

Hi Ppl,
How to disable autostart (application) when managed server restart ?
I want some of the applications to remain not started. In WebSPhere, we have an option disable auto start for applications.
I don't find in weblogic.
Thanks

Hi,
I agree with Faisal. When you shutdown your WL server while the application is running, the thing is when you start your server again, it would automatically start the application with it. Now if the application was down when you shutdown the server, it _the application_ won't start with the server.
So it depends on the application last state, when you start your server.

Redundancy for startup class.

Hi,
I have a startup class in weblogic server. This class acts as a daemon inside
weblogic server. What happens if this class goes down due to an exception after
a while ? does the weblogic server brings it up again or can we configure it or
is it just lost?
-Kishan-

It it runs in its own thread why don't you just do something like this:
public void run()
............ //initialization
while(!shouldStop)
try
catch(Throwable th)
th.printStackTrace();
and you wouldn't need anything like the functionality you are describing which I do
not believe BEA does.

Monitoring info not appearing in console for one of the managed server

Monitoring info not appearing in console for one of the managed server though server is running fine. It happens some times. I tried to get these info from executruntimeMBean, but that is also not returning any info for that server. The entry for that server get erased from running-managed-server.xml after some time. Any idea why?

hi Arun,
Please find the below diagnostic module config fom the condig.xml
<server-diagnostic-config>
<data-retirement-enabled>true</data-retirement-enabled>
<wldf-data-retirement-by-age>
<name>DomainHealth_WLDFRetirePolicy_m2ap5</name>
<enabled>true</enabled>
<archive-name>HarvestedDataArchive</archive-name>
<retirement-time>2</retirement-time>
<retirement-period>6</retirement-period>
<retirement-age>1</retirement-age>
</wldf-data-retirement-by-age>
</server-diagnostic-config>
This configuration was present earlier also, but it looks like the logs statrted accumulating recently due to some other changes made to console. There is nothing coming under the WLDF console extension in server admin console.
Other than changing the start script, will it be fine to go the file location ./server/data/store/diagnostics/WLSDIAGNOSTIC**.DAT and delete the older file while the server is running now?
Incase not posisible , an example on the change in startscript and the config.xml will b helpful
thanks

How to add an object in JNDI when a server starts?

I have an integration app. The app contains EJB project. The project contains EJB which reads data from LDAP.
My first version of EJB contains the following code:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, strProvider);
env.put(Context.SECURITY_AUTHENTICATION, strAuth); env.put(Context.SECURITY_PRINCIPAL,strPrincipal); env.put(Context.SECURITY_CREDENTIALS,strCredentials);
DirContext dirCtx = new InitialDirContext(env); // exception
All connection properties are hardcoded and it is not a good practice.
Also I can put those properties into deployment descriptor. But I am going to have some EJBs and each EJB has to have those properties into descriptors. It is not useful.
My idea: I would like to have whatever object which is called automatically when a server starts; this object creates InitialDirContext and put the context into JNDI. All EJBs lookup the context by a name. But I don't know how to do that.
And another question: how to change connection properties dynamically? My idea is putting the properties in XML Cache. And my object (which creates InitialDirContext) reads the properties from XML Cache. Can I handle a message that my properties in XML Cache have been changed and in this cases my object reads new properties and calls rebind() to update InitialDirContext?
Thanks,
Ivan

To bind an object into the JNDI tree check the documentation here:
http://e-docs.bea.com/wls/docs81/jndi/jndi.html#475702
If this is to be used by all your applications that you deploy on the server check out the startup/shutdown class documentation here:
http://edocs.bea.com/wls/docs81/ConsoleHelp/startup_shutdown.html

Help-Cubes are not getting started when Analytical server started in 11.1.1

Installed Oracle Essbase Analytical server along with Shared Services, Provider Services and Integration Services thru EPM v11.1.1.3. Shared services and provider services on Windows 2003 and Essbase Analytical Services and Integration Services on UNIX/AIX. All the components got configured successfully. Copied the essbase.sec from the server which has previous version (v11.1.1.1.0) of Essbase. We have been encountering couple of problems. The first one is the applications(cubes) didn't start when the analytical server started. The second one is when trying to start using MAXL script, the applications took long time (more than 30 minutes) to start.
Any suggestions that you may have in resolving this are appreciated. Thanks,

In the application properties, is the box 'Start application when Essbase server starts' checked? If not, that's why they didn't automatically start. Also, once you started them manually, does it still take 30 minutes to start? Or is shutdown and startup faster now?

Security settings for startup class

Hi,
I use WL6.1 (sp2) where the "guest" user is disabled and server starts up with
"system" user. All beans are permitted to be launched using other user "user1"
and not "system" user. And the jar file with beans and other staff is deployed
well, except of one thing:
I have startup class in the application and it doesn't work. When trigger method
is launched, the following exception is thrown:
<WispConfiguration: Can't connect to bean. No configuration avaiable java.rmi.AccessException:
Security violation: insufficient permission to access method; nested exception
is: java.lang.SecurityException: Security violation: insufficient permission
to access method>
As i understand this is the security problem. How could I configure weblogic
to make him to use "user1" instead of "system" when running startup class? Where
should I define it: in startup() method of startup class or in configuration files
of WL?
Any help/hint will be very appreciated.
THANKS
Orly

i took all the folders out and restarted and the same message came up that the startupitems folder is insecure and a second message saying that folder DS_Store in the startupitems folder is disabled because of insecure settings. Now I can not see that folder in the startup items folder, any idea
Probably just as it says, DS_Store is corrupt. This stores the settings for a folder.
To see if we can find the invisible folder and remove it open Terminal in your Utilities folder and at the prompt copy and paste defaults write com.apple.finder AppleShowAllFiles True; killall Finder
If you can see the file now just delete it.
Then, switch back to visibles only and create a new folder called Startup Items.
defaults write com.apple.finder AppleShowAllFiles False; killall Finder
Or, simply creating a new Startup Items folder may be enough.

Weblogic Server does not show managed server started when I used the Windows service to start it.

I created a windows service to start a managed server and the services was created successfully and stated. WHen I go to the Weblogic Server Admn console, the server is still showing shutdown. Whenm I try to start it, it returns with error that the the service is not able to start. Has anyone ran into anything similar. I am running on Windows Server 2008R2 and running Weblogic Server 10.3.6 and Fusion Middleware 11.1.6.

Notify when managed server restarts automatically after a crash.

I am trying to see if there is some way I can be notified (by email) when a managed server a cluster restarts automatically. I am running Weblogic 9.2 on Solaris Sparc 5.10.
I can certainly compare the PIDs of the last and the new JVM but am looking for a slick way to do it especially at the Node Manager level.
Thanks.

Hi,
*The server was started in warning mode and the JTA was declared unhealthy. I saw 2 transaction alive for more than 2000 seconds which is uncommon.
*The resource adaptor was started properly.
*We are using file store. But will it make a difference?
Thanks!

if so, how did you achieve this?

Propagating JAAS Subject for startup classes

Do startup classes have to login before they can access secured
resources in WLS 6.0? I notice that WLS 6.0 asks for a password before
starting the server. Is the "subject" created by that login somehow
propagated to startup class threads (and their thread offspring) or does
this have to be done manually?
I want to try to set up startup classes using a security style similar
to the Unix init process. It starts up as root and then starts its
services/daemons using something like:
su - foo-user foo-daemon
The foo-daemon runs as foo-user and, in Unix, so does every process
forked by the foo-daemon. I would like to use a parallel approach in
WLS. Can it be done?
Thanks,
Tim Taylor

Hi,
That's what I think too. I guess the only way to get the credentials is to
use a weblogic specific class that allows you to login an user from a servlet/jsp.
It does returns the Subject instead of a principal, so you can get the credentials...
seems like we'd need to change the J2EE api to further integrate JAAS with it.
Welll... back to handling security on my own :\

I`ve written a LoginModule that does user authetication and loads alluser

These credentials are app specific classes like WindowPermission.
How can I have access to these credentials from a servlet/EJB? Is therea

Libraries for Human task in managed server

Hi All,
We are using SOA Suite 11.1.1.6 for the current project. I have a questions regarding the setup of the managed server for Human Task Flow. For specific reasons, in our domain, we have three managed servers: admin, soa and taskform. The managed domain "taskform" will hold all ear project for human tasks.
The question is while configuring the domain, which libraries should we install in the "taskform" managed server?
Thanks in advance.

Hi,
Have a look at
http://docs.oracle.com/cd/E21764_01/integration.1111/e10224/bp_designtf.htm
section 28.8.4 How To Deploy a Task Form to a non-SOA Oracle WebLogic Server
This is the 11.1.1.5 documentation I am sure there would be an equilivant in your version.
In theory the URL should be provided by the deployment process but you can check this
In EM click on the composite with the human task component in it
Under Component Metrics click on the human task component
In the Administration tab you should see an entry which is the URI to the task form
As I said I havn't got this working on our system yet and I would be intrested in hearing if you are sucessful

Lifecycle functionality for startup class at ear level

Hi,
I've searched and searched and read through a great deal of the R3 (10.1.3)documentation, looking for the ability to initialize a thread/class at application startup time at the ear level. I see where it is documented how to initialize a servlet at application startup using the "load-on-startup" tag, however, I have been unable to find any documentation outlining how to do so at the ear/EJB container level.
Is my only option to put together a servlet that calls/starts my ejb level class/thread and then configure that servlet for "load-on-startup"?

Lest you thought nobody has looked at your post, here I am, with a negative answer though. I do not think there is a lifecycle functionality for startup/shutdown class at ear level in oc4j. There are startup/shutdown classes that are called after OC4J initializes or before OC4J terminates, which is not what you are looking for either.
