Performance overhead of using JRockit management console

Hi,
I wanted to know what is the overhead of using jrockit management console? We have enabled the management server in our production environment and started the actual console on different windows box.
Is it ok to have the console running in production environment? what kind of performance impact this will have?
I read through BEA docs and it says the performance impact will be negligible, but wanted to check any experience in community.
Thanks,
- Pritam.

Hi Pritam,
I don't remember what the console overhead is, but it is in the order of "low single digit % or less".
We have measured standard JRA recording overhead to 0.5% on SPECjAppServer scores, with optional lock profiling enabled that grows to ~3.5%.
Connecting the Memory Leak Detector increases GC pause times by maybe 10% but has no other impact on throughput.

Using the management console in less-than-ideal network topologies

I'm interested in using the JRockit management console for investigating
performance issues happening on customer sites. However, the management
console's method of communication with the server doesn't appear to be
very tolerant of tunneled connections (which would be the most
straightforward approach), on account of the management client starting
a new connection with an address and port provided by the server --
which is likely not to be an address and port which, from the client's
location, will actually reach the server.
Even if I were to start a non-tunneled connection from our VPN host
(which is less than ideal, as this system is headless), it would fail on
account of being given the server's primary address rather than its VPN
address. Setting jrockit.management.address at application server
startup isn't an acceptable solution as we may be starting the JVM
before the VPN connection has negotiated an IP, and restarting the
application server every time the VPN resets is an entirely unacceptable
approach.
If anyone could suggest a workaround, it would be appreciated.
Putting a rework of the management console's connection method on the
TODO list such that some future version of JRockit doesn't have this
issue would be a Good Thing as well -- particularly were it to occur
before IPv6 becomes widely deployed enough to make the issue moot.

I got my first MB about a year ago. Since this is your first MB, I'd suggest that you "play" with it first to get used to it.
After consulting this forum (and since my MB was after all brand new with no important files to backup), I did a "fresh" install from the installation DVD that comes with the MB (instead of deleting unwanted files). You do this by putting the DVD in your MB, restarting it and holding the C key.
I can't remember the detailed installation instructions, but they were quite simple and straightforward, and I just followed them as they appeared on the screen.
I do remember that I opted for the "erase and install" option which completely erases the destination volume and then installs a new copy of Mac OS X on the MB. There is also an option where you can select which programs you want to install (so that you can free up hard disk space).
After installing Mac OS X, you'll have to configure all of your computer settings (just follow the instructions on the screen), install iLife applications (which are provided on a DVD with a new MB) and other 3rd party applications you might be interested in (some of which can be downloaded for free from the internet).
While you won't be using Office for Mac, you may want to try Neo Office (just google for it). It's free although donations are appreciated.
Last but not least, my MB has been trouble free and my overall experience has been very good.
I hope this helps and enjoy your new MB.

Jrockit Management Console

I have a JRockit JVM running on a linux server. I have the -verbose option set on the JVM and I see where the JRockit Managment Console is started on port 7090.
I want to be able to connect to this JVM instance using the Management Console on my Windows machine. It won't connect. I keep getting an error message about Connection not accepted on the port for the machine in question. Can you connect to a remote JRockit JVM?

Hi Cassandra,
I suspect the problem may be related to your WLS settings, and I am unfortunately no WLS expert. Could you try compiling and running a very basic java program (that for instance does while(true){Thread.sleep(1000); Thread.yield();}) with the JRockit you're trying to monitor? Use -Xmanagement and -Djrockit.managementserver.address=<ip of interface used for comm. with console>. Don't set a security manager.
Kind regards,
Marcus

JRockit Management Console - Exception Count

Hello,
I'm using jrockit-j2sdk1.4.2_04. I download the JRA from: /wljrockit/docs142/JRA.zip. I started the Management Server with Tomcat 5.0. After starting the management console the exception count continuously increases one per second (approx). Is this a bug? Am I doing anything wrong? Can I drill down to see whats happening somehow?
Thanks,
Ralph

You can run JRockit with the (undocumented and unsupported) option -Djrockit.printstacktraces=true to print out every exception that happens. This will probably tell you what the exception is.
One exception every second is nothing to worry about from a performance pespective.

Connecting to the Database using the management console

Hi all,
When I login into the web based management console , I am able to see my system ( and also register other systems 0
However, when I click on the 'Database' - I am required to supply a "User ID" and "Password"
I tried everything : my SAPGUI user/pass , a database user/pass , the <SID>adm unix user/pass - nothing works.
What exactly goes there ?
Appreciate your help
below is a print screen of the user prompt I am getting when clicking the database component on the left

Hi
thanks for your reply
So , if I understand you correctly , this userid/password is the unix account <sid>adm credentials.
Well, if I understand the articel correctly , you need to either have write permissions for the sapstartsrv executable ( which my admin account currently do not have ) OR have the service/admin_users parameter set with the admin account
So I added the service/admin_users = <my admin account> and bounce
Did not help.
I also have :

Uploading EJB Jars using Enterprise Manager Console

I realize most publish their EJBs as an "ear" and their web modules as "war
But, what if I want to publish my ejb as a "jar" component? The Enterprise Manager Oc4J home has buttons for uploading WAR and EAR components only.
Please suggest work arounds.

Our forthcoming 10.1.3 release will support the additional deployment of standalone JAR files for EJB applications from Application Server Control (EM).
In earlier releases you can either:
1. Wrapper the JAR file witihn an EAR file and deploy that.
2. Manually deploy your JAR file to the default application using the j2ee/home/application.xml file by adding an entry such as:
<ejb-module id="jmsrouter_ejb" path="../../home/applications/jmsrouter-ejb.jar"/>
Note that in an DCM managed environment, this form of manual deployment not a recommended option. Make sure you notify the DCM repository of this type of change using "dcmctl updateConfig".

JRockit Management console unable to find classes in Method profiler

I have no problem to connect the console to the right JVM.
All tabs work OK so I can see memory and CPU usage. I can even do Method profiling on plain Java objects like String and Long but whenever I specify one of my classes (full path name) I'm unable to find them.
Any help would be really appreciated,
MV

Hi,
We've tried this internally now, and it works as designed - as long as the class has been loaded, i.e. if any classloader has loaded the class, it will be reachable and should show up properly. If the class hasn't been loaded yet, however, it will not show.
For instance, say a class C is reachable by only loader L. Trying to retrieve the methods of C before it has been loaded by L will fail. After L.loadClass("C") or similar has been executed the class should show up.
Kind regards,
Marcus

WLS server JVM disappears mysteriously after using management console

Has anyone had a problem with the server process JVM mysteriously disappearing after
using the management console? I am able to login to mydomain, configure a JDBC connection
pool, and then a Tx Data Source. But when I set the chosen target for my Tx Data
source to mydomain and hit apply, the server dies.
This has happened with both WLS 7.0 and the new WLP 7.0 installations. I'm running
WinXP Pro, WLP 7.0, and SQL Server 7.0. I suspect it's a config related issue.
thanks,
Ron

Ok, I understand that it's not support. When is support for Win XP slated to be available
then?

Disconnect object using a script (not from FIM Management console)

Hi,
Is there any way to disconnect a connector from its connected Metaverse object using a PowerShell command or wathever?
For the moment we use the Management Console to achieve this operation by clicking on "disconnect" to force the connector to become "disconnector".
Thanks for your help.

Thank you for your reply,
The deprovisioning process works fine and is not the purpose of what I want to achieve.
What I want to do is to disconnect an Connector from a MV object to reconnect it to another MV object because the join rule isn't valid anymore.
The case is as follow :
An Active Directory user is linked to an identity in our Identity Management System using a UserID which is mapped to employeeId attribute in AD user.
If the employeeID in AD is modified (by another Management Agent for example), I want to connect the user, with the new employeeID, to the correct MV object and hence to the correct ID in our system.
The main idea is to store some information from AD user such as UserPrincipaleName or sAMAccountName in the correct identity.
Unfortunately, the join rule isn't evaluated for the "connected" Connectors but only for "disconnectors" (unless there is an option to re evaluate the join rules for all objects that I don't know).
So to connect the user to the correct MV object, I have to disconnect manually the Connector to make it disconnector and re-sync. The sync process connect automatically the user to the correct MV Object which provision attributes from AD user to the right
ID and "delete" attributes from the former ID in our system.
Thanks for your help.

Solaris Management Console and root pasword

I upgraded to Solaris 10 last night and tried to perform some admin work to user accounts, using Solaris Management Console. When performing the task, Solaris wants to verify user and password, the root password fails. The root pasword is correct because it let me login as root. Solaris Management Console rejects all passwords for verification. Help me please.

Thanks for your help. I updated my root password from 4 charcters to 4charcters + 4 numerals , still SMC will not let me in. I updated 2 machines and both allow me to login as root (GUI) but SMC wants to confirm the password and will not let me in.
I have reinstalled (initialized rather than upgrade) Solaris 10 on one machine (Ultra60) , that machine now works fine. It allows me to login as root(GUI) ans the SMC accepts my root password
The machines are an Ultra10 and an Ultra60.
I choose to upgrade rather than a new install because of to much info to rebuild.

Solaris Management Console Error

I have installed Solaris 9.0 and I am using Solaris Management Console 2.1. I am trying to change the shell of the 'root' user . When I make the change I get the following error message :
"The management server cannot perform the operation requested
if this problem persists, refer to the log Viewer for additional information and contact your Sun Microsystem support provider.
The actual error reported was:
User root was partially modified. See the error log for further details "
I have seen that the changes requeted( change shell in this case) does actually take place although the SMC complains. Where is the error log and how do I see it ? I fail to understand why this happens. Any help will be appreciated.
I have also noticed that when I make any changed to other users SMC does not complain.

Enterprise Manager Console on AIX 5L

I installed 10g on an RS6000, istall went great and I was able to access the database via the web console. 2 days after the install I can no longer access the web console. When I attempt to access it, the browser times out after a while saying the page cannot be found. If I try to stop the service using emctl stop dbconsole that hangs indefinitely. I verified that localhost is correct(127.0.0.1) and the agent is running. How can I stop and start the service without shutting the machine down. I can start and stop the database from sqlplus and can connect to the database using Enterprise Manager but I cant seem to get the web interface back.
I am sure I am using the right port and have tried several things I read in other posts with no success. I can even check the status of the em agent from a browser and verify that the web server is up on port 5500 but I cant access the dbconsole.
Any assistance would be greatly appreciated.
Thanks,
Jon King

I didn't try if EM present somewhere on network to access XE.
