9iAS, OC4J and JVMs confusion

Could somebody please comment on, or shed some light onto the following:
With the previous (up to 1.0.2.1) 9iAS application server offerings, mod_ose and Java code execution inside JServer/Aurora were touted as the way to go, because of its optimized, multiuser, session-isolating nature.
We now got the new OC4J J2EE platform (i.e. Orion Application Server) which supercedes the previous offerings and whose documentation states it executes under the native JVM of the machine.
Question: Is it Aurora that is actually running Orion in the 1.0.2.2 config, or is it a plain JVM? If a plain JVM, what's the deal with the (theoretically apparent) benefits that Aurora offers for intensive multiuser scenarios? (session isolation, gc per session etc?). Can somebody from Oracle offer some clear clues as to where the application server platform is actually headed? Are we to expect an integrated Orion-based app server running on Oracle's JVM technology, is this already the case now, or is Aurora being silently phased out in light of the newer JVMs/JDKs that will soon hit the street?
Curious,
Thanassis

Hello,
The EJB container in 9iAS runs on JDK not on Aurora JVM. So the new direction is that the middle tier is separate from the database. In spite of the architectural strengths and theoretical benefits of the Aurora JVM we found that the EJB container performs significantly better and is far more usable in 9iAS.
So the future direction is that EJB in the Aurora container will be desupported over time. The middle tier story for Oracle will rn on JDK. The Aurora VM in the database will however remain for Java Stored Procedures.
Cheers,
Asho

Oc4j and JVM

Where I can obtain information detailed on the use of instances of jvm in OC4J and possible behaviors of this.
We setup a container to make use of 2 virtual machines ( in the numprocs parameter in the opmn.xml file ) when we do opmnctl status command the instance shows two processes alive.
But when we observed the logs, only the first instance is modified. I want to know if is possible to balance the requirements to the 2 jvm? how to do it? or where i can found information about that?
Regards.

Hi Edgar --
But when we observed the logs, only the first instance is modified.
I want to know if is possible to balance the requirements to the 2 jvm? how to do it?
or where i can found information about that?Can you explain a little further about what you mean by first instance modified -- what operation are you doing? What logs are you looking at? You may have observed this already, but when you run with multiple procs, each process (ie JVM) has a separate log file -- colors~blue~colors~1.log and colors~blue~colors~2.log for example.
When you have multiple processes running for an OC4J instance, then incoming client requests are automatically balanced over them.
It's really helpful when you post questions if you state what version you are usign too -- there are some differences between the releases.

ADF Application + OAS 10.1.3, how many OC4J and JVM ?

Hi all,
We are running in Production with ADF (BC+Faces) 10.1.3 in OAS 10.1.3, with maximum 300++ users.
(but not nessarily all submit request on same time)
Intermittently (about two times) a week, there is time where user get hung and all request take forever to get responded.
We watch during that time that DB load is not high, and OAS CPU 99.9 %. We have 12 GB RAM installed on OAS.
Then user have to restat the OPMN to make system responsive again.
Currently we run on one OC4J instance with 1 JVM, with 3GB heap.
My question is :
1) Will it help if we add 1 more JVM to the OC4J ?
2) WIll it affect the Application behaviour ? (if running in 2 JVM compared to in 1 JVM like now) ?
Thank you very much,
xtanto

Xtanto,
yes you will need to retest it.
Why?
Because it is highly possible session will be 'transported' between JVM's
There is a chance your application will not deploy/start at all on distributed JVM's, this because ALL objects stored on the session need to be serializable.
When this is the case, the application will deploy/start on multiple JVM's
But this doesn't resolve issues around developers who put random stuff in the session which is a bad practice in general.
Session behavior will need to be tested.

TopLink and 9iAS/OC4J 9.0.2

We are working on project that have
to work with 9iAS/OC4J 9.0.2, upgrade
to OC4J 9.0.3 in NOT an option.
Our J2EE application will only use
Servlets/JSP (NO EJBs), we need
to do O/R mapping from Servlets to db.
How can we install / use TopLink (9.0.3
or earlier version) from 9iAS/OC4J 9.0.2 ?
Regards, Radomir.

Hi Radomir,
This shouldn't be a problem, the easiest way to set things up would be to place the TopLink.jar file in the \j2ee\home\lib folder of OC4J v9.0.2. If there is something specific that you would like answered in terms of application deployment or setup and configurations, just ask.

Multiple BC4J apps deployed in single 9iAS OC4J instance

Deploying my BC4J/UIX applications in a single Oracle 9iAS 9.0.2 OC4J instance, causes some of my applications not to find their BC4J configurations. After restarting the OC4J instance some applications start to find the configurations, while some lose the ability arbitrarily. When I deploy each of them in a different OC4J instance, then everything works fine.
The problem appears also at my client's site. My client has all the latest patches applied to the 9iAS server and they can't afford upgrading to 10g or running every application in separate OC4J instance.
The BC4J/UIX applications are developed with JDev 9.0.3.4. and the BC4J and UIX libraries of the application server are updated to the versions of JDev 9.0.3.4. My development Oracle9iAS runs on Windows 2000 and my client has it on Sun Solaris.
The error trace I get from applications that can't find the configuration looks like this:

Is deploying multiple BC4J applications in single OC4J instance supported?

OC4J and FOP installation

Hi,
We would like to use the PDF printing of 3.0.1
I am trying to install FOP but I do not have any knowledge in OC4J and Java ... so I am kind a lost right now.
I am following the installation guide of OC4J standalone (http://download.oracle.com/docs/cd/B32110_01/web.1013/b28950/install.htm#BABIBGCA)
I was wondering :
1- do I need to install oc4j standalone in a separate Oracle Home ?
2- There is already an OC4J installed in my db Oracle Home , I guess for emdbconsole. So , I created a new directory called oc4j_sa and unzipped the file. When I start OC4J with oc4j -start , it does not give me the prompt back. Then , I can access the web page with port 8888 (192.168.0.21:8888) , but 192.168.0.21:8888/em fails . So I cannot deploy the FOP war file.
Any pointers or guidance would be great.
Thanks
Francis.
P.S. :
Oracle 10.1.0.5
Oracle Linux (RH 4)

OK, I finally got to the deployment of FOP but now it generates a corrupted PDF.
Are there any log files that I can check ?
I created a new Oracle_home for OC4J and ran "EM" to deploy FOP and everything worked like in the viewlet.
Now I did the setup in APEX and set the following :
Standard Support
Print Server Protocol HTTP
Print Server Host Address 192.168.0.21
Print Server Port 8888
Print Server Script /fop/apex_fop.jsp
I created a sample application to test. In a report , I added the print link.
When I clic Print, the pdf generated is corrupted and does not work.
Thanks
Francis.

You cannot use Internet Explorer on Windows Vista to run Web Forms.
<p>But you CAN run web forms through Netscape or Firefox. But you first need to disable Java in the browser.
<p>And to run OC4J on Vista, you need to set its compatibility mode to Windows XP.

Report display is different in report builder, local oc4j and app server

Hi guys,
we upgrade reports from sql report writer into report 10g. In the report 10g builder,
the report format looks fine. but if i use the url as below
http://applicationserver/reports/rwservlet?report=test.rdf&userid=username/password@service&desformat=pdf&destype=cache
so the format will be mess up whatever i use this url in my local oc4j or i deployed it into 10g application server. and the format is different in oc4j and application server. Why this issue happend?
Thanks in advance,

Just got 8520 and very confused, could i have some help please.

Hey
Right just got this phone and im confused.
Firstly how do i update? i tried using the thing on the site and it said there was no updates yet im on 4.6?
And also how do i download app world as when i tried it said something about not being able to open the page when i did it via the phone?
Thanks in advance
Jonny

Ok, I'm finally at a computer. Try setting up your BlackBerry ID using this site from your computer: http://uk.blackberry.com/id/
This will make it much easier to create the ID, and you should then be able to log into AppWorld using the BlackBerry ID you just created.
And as a heads up, you can also download apps from AppWorld to your phone via your computer using the online BlackBerry AppWorld webstore: http://appworld.blackberry.com/webstore/
If you want to thank someone for their comment, do so by clicking the Thumbs Up icon.

9ias 10222 and Portal 30985

I'm running 9ias r1 and Portal. I'm trying to tweak it so that when a user changes their password, the user cannot use the previously used password. So when a user changes their password, they have to use a password that is different than the one they used previous to the current. Does anybody have any ideas for me?

I'm not aware of a publicly available portlet for Oracle9iAS email as of yet.

sender,
the quantize menu is in the top info box in the arrange.
if you double click on it, an extended parameter box appears with a lot of quantizing options. also RTFM about this bit.
in the sample editor, there is an audio quantize feature.
but it is old, and probably hasn't been updated in ten years........try it, you
'll prolly hate it.
there is also a quantize audio/groove plug, in the special menu.
it works....sorta.
if you're talkin' drums, on seperate tracks, like kik on one, and snr on the next, etc., try strip silence to cut the loop/file up, then select same in the arrange trk and quantize this, as above. (info box).
this does work well provided you know just where you want the feel to be.
you could also try making a groove template of the original clip/loop and use this as a timing reference.
this also works well if you can get a clean footprint of the audio.
best,
DR9

Error when accessing Java and JVM section

I'm getting the following error when accessing the Java and
JVM section of the CF Administrator:
"Element JDKPATH is undefined in FORM"
I've searched a lot and there's very little on the topic. On
this forum there are two posts and one got no answer, on the other
it was suggested it might be the jvm.config file. I've looked at
mine but I really have no idea what could be wrong. Also, there are
two jvm.config files in my install, one in jrun4/bin and another in
jrun4/servers/cfusion/cfusion-ear/cfusion-war/WEB-INF/cfusion/runtime/bin
folder (I did multiserver installation).
I've already tried a bunch of things and no luck, any help is
appreciated on this.

How Standalone OC4J and the Oracle Application Server linked to each other

Hi ,
Please let me know what is the relation between a Standalone OC4J and the Oracle Application Server ?
In my application The Oracle Application Server is installed in C drive and there is a Stand alone oC4j .
Please tell me how they are linked to each other .
Thank you .

It depends on your need and what features and functionality of Oracle Application Server you are interested in. Note that OC4J is a component of Oracle Application Server that can run as a standalone component or within Oracle Application Server. Question #6 in earlier mentioned FAQ document states:
OC4J standalone is J2EE 1.3 compatible (1.4 and 1.5 too in later releases of OC4J) and is able to be used in both development and small scale production environments. OC4J standalone provides its own inbuilt HTTP/S listener to allow clients to execute Web applications that it has deployed. Application deployment and server configuration of OC4J standalone is performed by the manual editing of a simple set of XML files.
For large scale enterprise deployments, the Oracle Application Server product is likely to be more suitable with its comprehensive feature set including Oracle HTTP Server, process monitoring and management capabilities, and its configuration and management console.
So if you are happy with what you see in standalone OC4J and scalability isn't an issue for you, you can stay with standalone OC4J and don't need to move to Oracle Application Server.
PS: If you do decide to use OC4J that's embedded with Oracle Application Server, you can't move your standalone OC4J inside Oracle Application Server. You will have to reconfigure embedded OC4J again (as you might have done with standalone OC4J) and redeploy your applications.
Hope this helps.
Thanks
Shail
