Oc4j in Production

Hi all,
I'm trying to upgrade from SA to OBIEE 10.1.3.4.1 and I'd like to understand the need for the standalone oc4j. We use ISAPI plug-in and IIS. From the Oracle doc (ID 968223.1), it's not recommended to use oc4j in production environment and Oracle tech support says it's not certified. So besides using OAC/WebLogic/other true application server, what other options do I have? Is oc4j even needed in order to run/deploy OBIEE? I try to stop all oc4j in OBIEE server, presentation server, web server and I still can access OBIEE.
Thanks in advance,
L

Thanks Madan. We do not plan to have BI Publisher or BIOffice installed.
Does that mean there is no need for us to have oc4j?

Use OC4J in production system

Hi together,
i have a small question: Is it legal to use the oc4j in a production system or it is only for development purpose?

All of the licensing questions should be directed to your local sales rep, they can give you the most accurate answer.
Hope this helps,

Best wasy to move OC4J from Production to Test MidTier

I've read the documents but I am still lost on the best way to move a OC4J instance to another MidTier
I have 3 separate OC4J instances that are deployed for 3 separate divisions that contain different apps.
What is the easiest way to move them to a different MidTier in a different environment. (in my case same OS,portal 10.1.2 just slightly different layout)
I have worked though the create a test from production and have my test up and running. I just need to deploy the production apps to the test environment. Both have separate MidTiers, Infrastures and database.
I know I can manually recreate OC$J instance names and then manually recreate the apps from the .ear files but is there a easier faster way to do this?
Thanks

Hi,
It's not a simple move, it's an upgrade...
So perhaps transportable tablespace can help you (export from 10gR1 and import into 10gR2 should be work).
Read the following doc for more info and sample :
http://download-west.oracle.com/docs/cd/B14117_01/server.101/b10825/dp_export.htm#i1006840
http://download-west.oracle.com/docs/cd/B14117_01/server.101/b10739/tspaces.htm#sthref1231

http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14231/tspaces.htm#sthref1267
Or export your db in dump file, on the new server, precreate your db as well, and import like for an upgrade :

OC4J EJBQL and EJB 2.0 features

Hello Debu Panda and All
I've got all howtos and I mangaged to get some parts of OC4J [Oracle9iAS (9.0.3.0.0) Containers for J2EE (build 020323.1689)] working.
There are still some issues that are stalling our development. Could you please comment on them, maybe providing an estimate of when they will be solved/implemented?
First of all, a little background. Our application uses many Java Swing application clients that connect to the EAR application in the container.
The ear application has the following structure:
All database access (Oracle 8i, located in its own server) is done exclusively by means of CMP entity beans. A entity bean may access other entity beans. There are workflow session beans (stateful and stateless) that access the entity beans. All clients see only the workflow session beans (session beans fagade).
Our applicatoin is complex, having more than 80 session beans and more than 25 entity beans (not counting entity beans that exist only to represent relationships among entity beans).
There goes the questions:
1) It seems that entity beans cannot currently be referenced by remote interfaces. We couldn't deploy our application using it. Since we could use only local interfaces fot entity beans, thats what is been done now.
2) There is no CMR supported. Is this true?
3) EJBQL seems to be very limited. In the howto examples there are EJBQL statements that compare two numbers. However, when we tried to use String comparisons, it didn't work. Here is the statement:
"SELECT DISTINCT OBJECT(p) FROM Person p WHERE p.name = ?1"
If I compile, package and deploy the ear applicatin with the above EJBQL statement, OC4J generates an exception when executing the finder method. The exception is:
"java.rmi.NoSuchObjectException: Session has timed out
at com.evermind.server.ejb.StatefulSessionEJBObject.throwPassivisat
ception(StatefulSessionEJBObject.java:188)
at Cad023Remote_StatefulSessionBeanWrapper0.obterPessoasPorParteNom

at com.evermind.server.rmi.RMICallHandler.run(RMICallHandler.java:8
at com.evermind.util.ThreadPoolThread.run(ThreadPoolThread.java:64)"
If I remove the where clause, the expection is gone. However, I get all records. ;-)
4) It seems that all EJBQL clauses must be capitalized. Is this true?
FINALY)
Is there a newer OC4J build that could use to get the development going? Do you know where there will be one? Is there any way of contacting the OC4J development team to report bugs?
If you would like, we could discuss it in private e-mail (please use my private mail [email protected]).
Thanks for your attention,

Hi !! OC4J 9.0.3 developer's preview has most features of EJB 2.0. We are working on updating on our docs and samples for EJB 2.0
Please look at the following URL that has some How Tos on EJB 2.0 features such Local Interfacea, EJB QL, etc : http://otn.oracle.com/tech/java/oc4j/htdocs/oc4j-how-to.html#ejb

Some colleagues and I are trying to port a large project from JBOSS to OC4J. We used JBOSS 3.0 (beta) in order to evaluate EJB2.0 features and see if we could use it. We already have OC4J in production, but only as a JSP/Servlet container. The next step would be to deploy our EJB application to OC4J.
We have read the material and it is written that OC4J (developers preview) is EJB 2.0 compliant. However, the specific documentation and the examples don't show how to specify OC4J specifc XML files. We absolutely need CMR and Local Interfaces, because we don't have the time required to downgrade our JBoss EJB2.0 application to the EJB 1.1 specification. We have over 80 Session Beans and over 20 Entity Beans.
Is there anybody there that can confirm that OC4J developer's preview is really EJB2.0 compliant? If so, could you send me some pointers to information about OC4J container specifc deployment descriptors? The docs listed at the web site don't have EJB2.0 features listed, nor does the Oracle samples.

HI,
I worked out CMR and EJB-QL with single bean.
Using CMR, it is possible to get one bean reference through other bean, but
When I tried EJB-QL with bean to bean navigation then I run into problem.

Oc4j generated finders in orion-ejb-jar.xml file causing errors

Any information or assistance would be greatly appreciated.
I have encountered a problem with the generated orion-ejb-jar.xml file.
It looks like the additional finder methods that are generated when the application
is deployed are incorrect from the 9.0.3 version to the new 10.1.2.0.2 version.
The original content of orion-ejb-jar.xml before additional finder syntax is added:
<finder-method query=
"NO_SYS_USER_OBJECT_HISTORY.USER_ID=UPPER($1) and
NO_SYS_USER_OBJECT_HISTORY.AUTOID NOT IN(
SELECT H1.AUTOID
FROM   NO_SYS_USER_OBJECT_HISTORY H1,
         (SELECT AUTOID
          FROM   NO_SYS_USER_OBJECT_HISTORY
          WHERE USER_ID=UPPER($1)
          ORDER BY DATE_TIME DESC) H2

<method-params>
   <method-param>java.lang.String</method-param>
   <method-param>java.lang.Integer</method-param>
</method-params>
</method>
</finder-method>
After deploying in 9.0.3 the following information is added to the orion-ejb-jar.xml file:
<finder-method query=
"NO_SYS_USER_OBJECT_HISTORY.USER_ID=UPPER($1) and
NO_SYS_USER_OBJECT_HISTORY.AUTOID NOT IN(

         (SELECT AUTOID
          FROM   NO_SYS_USER_OBJECT_HISTORY
          WHERE USER_ID=$1
          ORDER BY DATE_TIME DESC) H2

After deploying in 10.1.2.0.2 the following information is added to the
orion-ejb-jar.xml file:
<finder-method query=

The problem with the 10.1.2.0.2 generated finders is that it is prepending H1 when
it should be NO_SYS_USER_OBJECT_HISTORY which results in the following error:
Exception in thread "main" com.cdtelecom.vygroe.configuration.ConfigurationException:

I tried to manually edit the file but when I shutdown and restart oc4j it regenerates the file again.

Jingzhi -- If you define the correct EJB-QL you should get the correct SQL generated for the finder. If that's not happening can you verify it against the OC4J v903 production release and see if it is still happening. I don't know if this helps with the JDeveloper problem specifically but if you don't need to create your own finders then that I hope should help.
Thanks -- Jeff

Cant use log4j or commons logging with ease in OC4J/OAS 10g

Hi,
I have a simple JEE 5 app which just uses Log4J for logging. I have a log4j.properties at the right place. But deploying an EAR with this config fails
Operation failed with error: Lorg/apache/log4j/Logger;
or if i move to commons logging this...
Operation failed with error: Lorg/apache/commons/logging/Log;
Things as simple as using logging, I feel, shouldnt be any complex than what is inferred. Atleast there should more error detailing to it than a bozo message like the above.
Anyone used logging in just a ejb jar app???

We've run into this recently and were surprised to find out that Oracle not only "recommends" OAS over OC4J in a production environment, they require it. If you look at the license agreement that you accepted when you downloaded OC4J (you know, the thing that you never read) you'll find that Oracle expressly says that you are not allowed to use OC4J in anything other than a development environment.
So, after years of using it for several applications, we now have to switch to OAS. Actually, we are doing this not only to stay legal, but also to take advantage of mod_oc4j for reverse proxy. We could not get this to work under OC4J so we started poking around with OAS and then found out that we were not licensed for either in production.
If you are using OC4J in production, read the not-so-fine print. You are in violation of their license agreement.

Missing listener-threads attribute in orion-ejb-jar.xml !!

Hi All,
I was trying to do some performance tuning as given in BPEL admin guide. For one of the BPEL property namely 'dspMaxThreads', guide says "Sum of dspMaxThreads of ALL domains should be <= the number of mdb listener threads on the workerbean". Now when i open <SOA_HOME>/j2ee/oc4j_soa/application-deployments/orabpel/orion-ejb-jar.xml and navigate to workerbean, i can not find any listener-threads attribute in message-driven-deployment tag.
<message-driven-deployment name="WorkerBean" min-instances="100" resource-adapter="BPELjms">
However there is a ReceiverThreads property set to 40.
<message-driven-deployment name="WorkerBean" min-instances="100" resource-adapter="BPELjms">
<config-property-name>ReceiverThreads</config-property-name>
<config-property-value>40</config-property-value>
</config-property>
</message-driven-deployment>
Now my question is that can i add listener-threads attribute to message-driven-deployment tag and then tune dspmaxthreads accordingly, Or
i can make use of ReceiverThreads property to match with dspmaxthreads property. I am really confused b/w listener-threads and ReceiverThreads.
Can anyone clarify the same ?
I have ORACLE SOA Suite ver 10.1.3.1 (with 10.1.3.3 patch) installed.
Thanks in advance.

Do I have to use opmn:ormi in the JNDI Service Provider URL?

Trying to create a new Enterprise Message Source (JMS) and it's not updating the Data Object. Tested the OC4J queue using a Java POJO listener ... sending and receiving text message seems okay. I created a basic Plan (there's only one data element for now) and it is running.
Any suggestions would be appreciated!

Here is a document from Ranga on how to connect BAM to OJMS (hope it helps):
Database Trigger - OJMS - BAM Integration Sample
Last updated 07/27/05 Ranga
OJMS setup
Step 1 - Oc4j setup
     Install Standalone/Developer 10g OC4J or production version Application server.
Developer version download -http://www.oracle.com/technology/software/htdocs/devlic.html?/technology/software/products/ias/htdocs/utilsoft.html#1012 or from http://bamqa.us.oracle.com/bamqaWiki/attach?page=Downloads%2Foc4j1012_extended.zip

Strange ora-1403 and 6508 errors after compiling forms in 10.1.2.0.2

Hi, today we migrated our Application Server to 10.1.2.0.2 and totally unexpected (it was not mentioned in the upgrade guide of 400 pages...) we had to recompile all 9.0.4-executables
So we installed Developer Suite 10.1.2.0.2 and recompiled all libraries, forms and menus. There were no errors reported, so everything should be valid.
Now we can run the forms again - that is, they start without problems - but on some forms (so not all), after doing Run Query, we immediately get ORA-1403, followed by ORA-6508.
Could this perhaps be caused by "something" in the Headstart-libraries that can not be used in 10.1.2?
A quick respons would be perfect, because many users have problems now.
Regards, JW

Hi Josef,
indeed i recompiled them all and the errors are raised in development (running standalone oc4j) and production environment (application server 10.1.2).
Currently i'm migrating the forms to Headstart 65401 and i will update this thread with the results. I guess/hope that the obsolete forms functions/procedures caused these errors.
Thanks, JW

Finder-method in orion-ejb-jar.xml

Hi,
Is there a way to let jdeveloper 9.0.3 preview to automatically generate finder-method descriptors for us? When I was developing a cmp-based entity bean, although I defined the ejb-ql in ejb-jar.xml, JDeveloper still just generated the first orion-ejb-jar.xml shown below. In the first orion-ejb-jar.xml, there is no definition for any finder-method. I have to manually add my own definition to it, which is shown in the second orion-ejb-jar.xml. I know that the oc4j container will generate the finder-method after deployment, but in some situation it generated incorrect finder-method descriptors. One of such situation is the between query like "between ?1 and ?2". Anyway, if JDeveloper can generate the finder-method during development, then we can know whether the descriptor is correct or not before deployment, and we can make modifications before deploying it to oc4j server.

Any one has any idea?
Thanks,

Jingzhi -- If you define the correct EJB-QL you should get the correct SQL generated for the finder. If that's not happening can you verify it against the OC4J v903 production release and see if it is still happening. I don't know if this helps with the JDeveloper problem specifically but if you don't need to create your own finders then that I hope should help.

Configurable data-source in orion-ejb-jar.xml

Hi,
In my orion ejb-jar.xml file, I have hard coded data-source entries for all entity beans , i.e.
<entity-deployment name="Customer" data-source="jdbc/slldev02DS" table="CUSTOMER">
Is there any way, I can make this customizable, i.e. feed in or define a parameter?
thanks in advance,
Kevin

OC4J 10.1.3 production: Build problem Adventure Builder 1.0.1 using EJB 3.0

Hi all,
I tried to use the migration to EJB 3.0 of the Adventure Builder 1.01 from Debu Panda and had some build problems.
Does anybody know if this demo was tested with the production version of 10.1.3?
I used the standalone version and had to tweak a lot of entries in ant-oracle.xml.
Is it possible that the migration was done with a preview release? Have there been so many changes? I had to include a bunch of additional JARs e.g ${J2EE_HOME}/lib/adminclient.jar, ${ORACLE_HOME}/webservices/lib/wsclient.jar. ${ORACLE_HOME}/lib/xmlparserv2.jar
and others.
Also I had to change some task definitions as I guess that the contents of ${ORACLE_HOME}/j2ee/utilities/ant-oracle-classes.jar must have changed...
If I did not do something terribly wrong it would be nice if you could update the example to save other people from this nightmare of running from one build error to the next!
Regards,
Eric

Hi Debu,
thanks for your reply. I've used an previously installed ant 1.6.5 from ant.apache.org, but I don't think this should matter, or?
As far as I could see one of the problems is related to the version of ant-oracle-classes.jar in ${ORACLE_HOME}/j2ee/utilities which the example relies on.
In the adventure builder ant-oracle.xml you'll find task definitions like that:
taskdef resource="oracle/ant/taskdefs/deploy/antlib.xml" uri="http://www.oracle.com/ant/taskdefs" loaderRef="oracle.tasks.loader">which does not match with what one can find in ${ORACLE_HOME}/j2ee/utilities/ant-oracle-classes.jar
So from my point of view this has to be changed to
<taskdef resource="oracle/antlib.xml" uri="antlib:oracle" loaderRef="oracle.tasks.loader">I also had to change some libs... That's why I thought this example was made and tested with an earlier version of oc4j 10.1.3 (maybe a preview version).
Regards,
Eric

OC4J 9.0.2 production with JDK 1.4.0: mostly broken

I have tried OC4J 9.0.2 production with several combinations of JDK 1.3.1 and JDK 1.4.0 for building, deploying, and running a simple, home-grown EJB-based web service. If I build the EAR file using JDK 1.3.1, it will run fine on OC4J using JDK 1.3.1 or JDK 1.4.0.
I have thus far found it to be impossible to build the EAR file using JDK 1.4.0 and have it run sucessfully on OC4J using either JDK 1.4.0 or JDK 1.3.1. I always get the following when attempting to invoke the web service via the generated Java proxy stubs:

Notes:
1) When attempting to deploy onto an OC4J instance running on JDK 1.4.0, I have replaced the tools.jar file and modified the global-web-application.xml as per: ORA-92102 Timeout on Web Forms
2) I have verified that the EJB deploys correctly regardless of build and/or deployment environment.
3) Let's pretend that I can configure each of these environments to run under JDK 1.4.0 or JDK 1.3.1: run OC4J (fresh install), build ear, deploy ear, invoke web service. Here are the combinations I have tried:
BROKEN: run OC4J 1.4.0, build ear 1.4.0, deploy ear 1.4.0, invoke web service 1.4.0
WORKS: run OC4J 1.4.0, build ear 1.3.1, deploy ear 1.4.0, invoke web service 1.4.0
WORKS: run OC4J 1.4.0, build ear 1.3.1, deploy ear 1.3.1, invoke web service 1.3.1
WORKS: run OC4J 1.4.0, build ear 1.3.1, deploy ear 1.3.1, invoke web service 1.4.0
WORKS: run OC4J 1.3.1, build ear 1.3.1, deploy ear 1.3.1, invoke web service 1.3.1
WORKS: run OC4J 1.3.1, build ear 1.3.1, deploy ear 1.3.1, invoke web service 1.4.0
WORKS: run OC4J 1.3.1, build ear 1.3.1, deploy ear 1.4.0, invoke web service 1.4.0
WORKS: run OC4J 1.3.1, build ear 1.3.1, deploy ear 1.4.0, invoke web service 1.3.1
BROKEN: run OC4J 1.3.1, build ear 1.4.0, deploy ear 1.3.1, invoke web service 1.3.1
BROKEN: run OC4J 1.3.1, build ear 1.4.0, deploy ear 1.4.0, invoke web service 1.4.0
Is Oracle aware of this problem? What is causing it (e.g. class format change in classes compiled in JDK 1.4.0)? Are you working to fix it in the next release (either preview or production)?

I've also just downloaded JDK 1.4.0 and tried running the "Simple JSP Examples" that come with OC4J R2.
Of course these simple examples didn't even compile:
<blockquote>
500 Internal Server Error
OracleJSP: oracle.jsp.provider.JspCompileException:

package examples.jsp._num;
^
2 errors
</blockquote>
So whose fault is this?
Is it my fault for not reading this forum before downloading the 40MB J2SE 1.4.0 install?
Is it Oracle's fault for failing to point out that OC4J is compatible with ONLY 1.3.1 ?
Is it Sun's fault for breaking compatibility with their own product? So much for write once run anywhere. This is not what Java was supposed to be about.
