What OC4J Container?

Hi everyone
In eBS R12 on Unix , what is the script name for OC4J Container?
is it adoacorectl.sh, or not?
I am a bit confused.
And is Apache this one : adapcctl.sh ?
Many thanks

Hi,
Oracle Containers for Java (OC4J) is an Oracle Application Server component that replaces the JServ component used in earlier releases of E-Business Suite. Based on J2EE standards, OC4J allows execution of Servlets, Java Server Pages (JSP), and Enterprise Java Beans (EJB).
Oracle HTTP Server provides the foundation for the Oracle Application Server Web services. Built on Apache Web server technology, Oracle HTTP Server supports Java servlets, JavaServer Pages (JSPs), perl, PL/SQL, and CGI applications.

Shut Down Of OC4J Container ist blocked

Hi,
i'vi got a problem with the new 10g iAS and if anybody's encountered the same or does know a solution, please let me know.
The problem is:
I'm not able to stop the OC4J container in the iAS cleanly.
The reason is:
There are two timers (java.util.Timer) running. These timers are cleanup timers, which run always throughout the application at intervalls (scheduleAtFixedRate). If i dont start the timers, the container will stop right away, without any error. If the timers are running the container is waiting for them to cancel and shutting down hardly after a timeout.
I didn't have this problem with 9i and i dont have it in the embedded OC4J of the JDeveloper.
Is there any workaround? How could i latch into the shutdown process, to cancel the timers myself?
Best regards,
Mirko

The OC4J script is not the cause of this -- if the message is shown "shutting down OC4J' then the call has been made to OC4J and its in the process of shutting down.
If you execute "set verbose=on" before executing oc4j.cmd, then you'll see the command that oc4j uses when -shutdown is performed is exactly that command you suggest:
oc4j -shutdown -port 23791 -password welcome1Executing: D:\java\jdk150_11\bin\java -jar "d:\java\oc4j-10133-prod\j2ee\home\admin.jar" ormi://localhost:23791 oc4jadmin welcome1 -shutdown
But as you are suggesting there are manual ways to shutdown OC4J that are equally valid to use; it's a matter of choice.
What you could try is using the -force extra switch with the -shutdown command to force it to shutdown:
java -jar admin.jar ormi://localhost:23791 oc4jadmin welcome1 -shutdown force
If that fails, ctrl+c the process. It doesn't do any damage to it.
A thread-dump (ctrl+break) on the hung process can help to identify any deadlock issues.
oc4j.cmd is limited certainly, but it provides a simpler entry point IMHO for new users. And we still fully support/endorse the direct startup path using the runnable JAR file.

JNDI lookup help please-Bean to Bean callout locally in same oc4j container

Hi - I'm fairly new to oc4j/ejb coding - I'm trying to get a simple application running to show that our code can be run in local mode - here is the scenario:
- Bean A (our application bean) within Application A
- Bean B (customer-developed bean) within Application B
- Bean B calls Bean A
- Bean A + Bean B are different application instances in the same oc4j container
- Jsp (residing in ApplicationB) within the same oc4j container calling Bean B, which invokes Bean A
====
I get the following exception (classes renamed to match scenario):
javax.naming.NameNotFoundException: oracle.apps.applicationa.common.BeanA not found in anothercompany.applicationb.common.BeanB
[java] at com.oracle.naming.J2EEContext.getSubContext(J2EEContext.java:93)
[java] at com.oracle.naming.J2EEContext.lookup(J2EEContext.java:76)
[java] at com.evermind.server.ApplicationContext.lookupJavaCompEnv(ApplicationContext.java:265)
[java] at com.evermind.server.ApplicationContext.lookupJavaComp(ApplicationContext.java:132)
[java] at com.evermind.server.ApplicationContext.lookup(ApplicationContext.java:306)
[java] at com.evermind.server.ApplicationContext.lookup(ApplicationContext.java:120)
[java] at javax.naming.InitialContext.lookup(InitialContext.java:347)
- BeanA is part of application named "AppA" in server.xml
- BeanB is part of application named "AppB" in server.xml
- AppB has attribute 'parent="AppA"' in server.xml
- If I change the Jsp file (residing in AppB) to call BeanA directly in the jsp code it works with no JNDI error, but changing the jsp code back to calling BeanB (which then calls BeanA) will throw the NameNotFoundException
My Stateless Session Bean is very simple and I have tried not setting the context and setting the context. I'm thinking this is a very simple configuration issue, but have not been able to find the solution yet... I've tried playing with the setSessionContext method in the session bean but have had no luck and am not sure what to set the variables to or even if I'm in the correct method...
public void setSessionContext(SessionContext ctx) {
if (verbose)
System.out.println("setSessionContext called");
Properties env = new Properties();
// tried all three context factories...
//env.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.ApplicationInitalContextFactory");
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.ApplicationClientInitialContextFactory");
//env.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.rmi.RMIInitialContextFactory");
// not sure what url to put, if any
//env.put(Context.PROVIDER_URL, "ormi://localhost:23791/AppB");
env.put(Context.PROVIDER_URL, "ormi://localhost/AppB");
// tried with and without security principals... also tried sysadmin/sysadmin
env.put(Context.SECURITY_PRINCIPAL, "guest");
env.put(Context.SECURITY_CREDENTIALS, "welcome");
// mProps is a local transient member var of type Properties
mProps = env;
// mCtx is a local transient member var of type SessionContext
mCtx = ctx;
(edit) additional info:
- all beans/classes are in the same classes directory; there are no jar files, so in application.xml the specified classpath is "classes" which includes both appA and appB classes
- I verified that if I point (appB) jsp directly to BeanA it works with the "parent" attribute set on appB in server.xml, and when I remove the "parent" attribute on appB in server.xml the jsp throws a NameNotFoundException
edit #2:
another interesting note is that the exception message says "oracle.apps.applicationa.common.BeanA not found in anothercompany.applicationb.common.BeanB"
and usually the naming error I see is:
"oracle.apps.applicationa.common.BeanA not found in appB"
(as with the case when I use a jsp to access appA beans without setting the parent application of appB to appA)
- also my j2ee/home/applications/appB/WEB-INF/web.xml includes the oracle.apps.applicationa.common.BeanA ejb-ref tag
any help is appreciated - thanks!

Hi Steve
thanks for the reply - I currently have the parent attribute set in server.xml which is why the jsp connection works, but for some strange reason the bean cannot connect to other bean...
my server.xml has something like...
<application name="appA" location="appA" auto-start="true"/>
<application name="appB" location="appB" parent="appA" auto-start="true"/>
(ok, the tags might be off because I'm not in front of my workstation looking at the xml file...)
on another interesting note, in the session bean for AppB I've tried searching for the ejb bean for app B (itself basically) with the default initial context and it cannot find its own bean within the same application... the message would be something like "NameNotFoundException: anothercompany.applicationb.common.BeanB not found in anothercompany.applicationb.common.BeanB"

Sort order in Java application (oc4j container) -- ear file deployment

I have a Java application deploy in Oracle OC4J container (EAR file).
In my Java application (jsp), I have a SQL statement who return data but the
sort order is wrong. The letters "é" and all characters with accents
appears at the end of the result.
I tried many things to change the sort order (NLS parameters in database
and OAS10g parameter files).
When I use SQL*plus on database server, that's working.
The sort order is wrong when I use the java application.
Somebody can tell me what and where is the NLS parameters to change ?
Thanks
Robin

Robin,
I'm only guessing, but it could either be related to the java locale or the CHARSET attribute of the HTML header -- and nothing to do with the NLS parameters.
Maybe you should try the Globalization Support forum?
Good Luck,
Avi.

OEM in Linux and Unix Memory difference on Deployed OC4J Container

I have 2 Oracle 9iAS environments 1 each for production and test.
My Prod servers are on AIX (Unix)
My Test server is on Linux
Under Enterprise Manager If I create an OC4J container exactly the same in both and deploy an application exactly the same in both could someone tell me why the memory usage display is widely different - on linux its much more used than on unix?
Perplexing.

The code gets pretty messy as I have both a SendMail and MailMessage class that I use. Basically for not authenticated messages (I need authenticated), the example on metalink Doc ID: Note:234490.1 with subject "Mail Service Setup" is what I used to get this going.
I updated the local application.xml file located in C:\jdev1012\jdev\system10.1.2.2.0.1929\oc4j-config\application.xml
<mail-session location="mail/mailsession" smtp-host="my.mail.server">
<property name="mail.transport.protocol" value="smtp"/>
</mail-session>
On a datapage, I have a button with event_Email. In the action class I have an onEmail() method that calls the code to create a message and send it with the email transport.
In my libraries in JDeveloper, I created one called JavaMail which has activation.jar and mail.jar. This is added to the project.
Everything works fine when running locally. The problem is in deployment. The OC4J container that I deploy to has a java2.policy file. At first the classpath, and the location in the policy file for mail.jar and activate.jar were not the same. I updated the policy file to use the files in the classpath. Since mail.jar and activate.jar on the OAS server are in the classpath, I didn't include these files in the deployment.
When trying to run, I don't get any messages, just a 500 Error.
If I try to implement a policy file on the local OC4J in JDeveloper, I get lots of problems, and I gave up on that route.
Hope that adds more info. Thanks, Ken

Lcds/datamodeler inside oc4j container

good day,
     I've been able to deploy an lcds data modeled application into an oc4j container from a tomcat environment that works against an oracle db. After a lot of
errors and googling I got it to work by adding this to my WEB-INF/web.xml:
<resource-ref>
        <res-ref-name>jdbc/myDataSource      </res-ref-name>
             <res-type>javax.sql.DataSource</res-type>
             <res-auth>Container</res-auth>
</resource-ref>
so fiber could make the connection to java:/comp/ env/jdbc/ myDataSource configured in my fml file.
Now from flashbuilder4 /data Model 1.0 I try to connect to the lcds/rds under oc4j and I get no datasources found message, what additional plumbing to I do to get this to work?

You need to uncomment the RDS section in the web.xml file of your webapp. It is commented out initially for security reasons - RDS should not be enabled in a production environment. Also you probably want to set useAppserverSecurity to false as below.
    
    <servlet>
        <servlet-name>RDSDispatchServlet</servlet-name>
        <display-name>RDSDispatchServlet</display-name>
        <servlet-class>flex.rds.server.servlet.FrontEndServlet</servlet-class>
        <init-param>
            <param-name>useAppserverSecurity</param-name>
            <param-value>false</param-value>
        </init-param>
        <load-on-startup>10</load-on-startup>
    </servlet>
    <servlet-mapping id="RDS_DISPATCH_MAPPING">
        <servlet-name>RDSDispatchServlet</servlet-name>
        <url-pattern>/CFIDE/main/ide.cfm</url-pattern>

Debugging application/OC4J container

I have some application running in separate 9iASR2 9.0.2.0.0 OC4J containers that appear to randomly freeze (this happened 7 times in May, 2003). Only restarting the OC4J container fixes the problem. As far as I can tell, there are no obvious problems (db connectivity, OS problems, ...) that could be causing this freezing.
My question is, how do you go about trouble shooting debugging an application running in a OC4J container. What kind of tools should I be using? Jprobe?
Any help is appreciated.
Daniel

Hi Daniel --
Tools which act as profilers such as JDeveloper,JProbe, etc. can help assist with the codepath and possible source of a freeze.
Sounds like you've checked the right items -- I have seen instances where an application was leaking database connections in a side and infrequently executed codepath, which contributed to the system freezing.
Another option for freezes is to get the running JVM to do a thread-dump to see if there are any locks on objects that are leading to deadlocks -- this can be done on Unix by issuing a "kill -3 <pid>" on the running JVM process.

Does restarting oc4j container redeploys the applications

does restarting oc4j container redeploys the applications that are in that container?
Thanks.

No it should not. What version of OC4J (Oracle Application Server) are you using? And are you noticing this behavior or just curious?
Thanks

Default OC4J Container will not start

Hi,
I'm running Oracle Application Server 10.1.3.1. on SuSE Linux.
Just recently, I've been unable to start my default OC4J container.
When I try, I get any one of these errors:
opmn id=<host>:6201
no enabled components for this request
OR
Communication error with the server local port
OR
opmnctl: opmn start failed.
I cannot figure out what's wrong. I'm not seeing any errors in the log files; although I'm not sure that I'm checking all of the necessary logs.
Does anybody have any ideas as to what could have gone wrong?
Thanks much,
Nora

Hi,
I actually got it to start by editing the opmn.xml file. I increased the number of seconds for starting the default container before it times out. There were no errors that I could see in the log files; but it seemed like the apps were trying to start and then nothing.
That ended up working, but I haven't done another stopall/startall since then. I think it still might be acting a little wierd. But for now, I at least got it functional again.
Thanks for the reply,
Nora

Windows 8.1 (64) What is contained in the Machiekey folder and what would happen if it was renamed and replaced with an empty folder?

Microsoft support engineer, Mohamed Ameen, suggested I post this question/problem here.
I have a Windows 8.1 (64) PC that has a problem with a phantom or ghost Homegroup that is preventing it from becoming a part of a Homegroup on my home LAN. The Homegroup troubleshooter utility and all of the standard troubleshooting suggestions online have
been of no help.
I found this thread ("http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/homegroup-wont-go-away-ghost-group-on-whole/8a4f464f-e461-47aa-af05-07a4fd4875fd") which suggests replacing the Machinekeys folder, but it has very little
in the way of instructions on how to completely perform the "repair" and/or the risks of causing other OS and program failures.
I have added additional information and screen shots to the thread I started on the Microsoft Community site and rather than repeating all of that I thought it would be easier to include a thread to that discussion: (http://answers.microsoft.com/en-us/windows/forum/windows8_1-networking/what-is-contained-in-the-machinekeys-folder/d7fb5189-e8c2-4ec8-ba2f-9e4e53905703

Upgrade oc4j container from 10.1.2 to 10.1.3

Hi to all,
We use oc4j container 10.1.2 for old applications, but now we have developed ajax applications using oracle maps, but if i'm riight 10.1.2 doesn't support oracle maps.
I've tried to install oracle application server oc4j container 10.1.3 in the same machine(i must use the same machine with red hat 3.4.4 opertive system) but i see a lot of conflicts with 10.1.2 and i cannot install that properly.
Is there any possobility to upgrade oracle application server oc4j container without having a metalink account?Is there a patch or something similar?
Thank you,
Francesco Rizzello

There shouldn't be any problems, I have in the same server one 10.1.2 App Server and a 10.1.3 and no conflicts, only when I installed I had the first App Server up, so the second recognize the ports used and it use a diferent one for his components.
Can you tell about your conflicts?

Debugging or Running from OC4J container does not save to database

When I run a project locally, from the oc4j container, none of my user input is committed to the database, for example...
1. any changes to an lov input field are removed upon tabbing out of the field
2. any other changes are not saved, getTransaction().isDirty() is false
I am unable to debug any items that require user input. I don't know when or why this started happening.
Thanks,
jerry.

1. any changes to an lov input field are removed upon tabbing out of the field - may be the PPR event of LOV is handled in the controller's processFormRequest where the values are cleared
I am unable to debug any items that require user input. ----- are you trying to get the values of input items in the processFormRequest?
