Migration of Enterprise application (J2EE) from OAS 10G to WebLogic

Hi Group,
I am working on migrating Enterpirse application developed using Struts, Ejb2.0, JMS. Its been deployed on OAS 10G and Websphere, but I need to deploy the application on Weblogic 10.3. Please can you list me the steps that needs to be followed to migrate the application.
As per my understanding follwing things needsto be taken care of:-
1) Weblogic Descriptor files:
1.1 Weblogic.xml:- we added security roles and ejb-reference-description for the ejbs.
1.2 Weblogic-ejb-jar.xml for all the ejbs used in the application.
1.3 Weblogic-application.xml
1.4 Resource Adapter
2) JMS queue set up
3) JDBC set up
It would be a great help if you can let me know what are the steps to migrate the application.
Thanks and Regards
Deepak Dani

I suppose this paper is Oracle internal only at the moment.
If you have the option, try JDev 11g and setup all the JDBC and JMS stuff in it.

Migration from OAS 10g to Weblogic 10.3

Hello,
I migrate large app from OAS 10g to Weblogic 10.3.
1.
The main part of the job was to prepare descriptors for Weblogic. Unfortunatelly I don't find any tool that could do the job:( There are some problems with descriptors namespaces. This schema and namespaces given in 10.3 docs are not working (not available):
http://edocs.bea.com/wls/docs103/ejb/DD_defs_reference.html
So I use the one from 10 release in weblogic-ejb-jar.xml:
weblogic-ejb-jar xmlns="http://www.bea.com/ns/weblogic/10.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/10.0 http://www.bea.com/ns/weblogic/10.0/weblogic-ejb-jar.xsd">
and form 9 release in weblogic-cmp-rdbms-jar.xml:
<weblogic-rdbms-jar xmlns="http://www.bea.com/ns/weblogic/90" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-rdbms20-persistence.xsd">
There are also some bugs in docs about ejb relations.
After fixing some schema compliance exc this step success.
2. Next the EJBComplianceChecker - its much more restrictive than OAS verification. So updates in ejb interfaces are necessary. It is not a problem with small app but when there ale a lot of code/branches to migrate it's become a problem. I have been looking for some switch that could help with this but with no result/
EJBComplianceChecker - Spec veryfication level
3. Now after EJB compliance checker done its job with success I have an exception that I do not understand:
An error occurred during activation of changes, please see the log for details.
Exception
preparing module: EJBModule(corpo_ejb.jar)
Unable to deploy EJB: corpo_ejb.jar from corpo_ejb.jar:
There are 1 nested errors:
java.io.IOException: JDT compilation error! at

at
weblogic.ejb.container.ejbc.EJBCompiler.doCompile(EJBCompiler.java:357)
at
JDT compilation error!
Could you please give me some point where the problem could be? I don't have any idea where to start looking for..
What are your experiences with migrations from OAS to Weblogic 10?
Thanks in advance!

Images not showing up after moving from OAS 10g to Weblogic 11g

We are moving our oracle forms application from OAS10g to weblogic 11g. We have a simple login html page that has an jpg image. This login page is rendered properly under OAS 10g. After following the documentation for configuration, the login functionality works fine but for some reason the images on the html page do not show anymore. The images are located within the same directory as the html page
C:\Oracle\Middleware\asinst_1\config\FormsComponent\forms\server\index.html
C:\Oracle\Middleware\asinst_1\config\FormsComponent\forms\server\myimage.jpg (this does not render).
Does anyone have any suggestion about this?
thanks,
Wes

I'm just noticing this tonight, too. I had Lr3 scan for missing photos. It identified 388 out of about 20,000. In checking on that, I tried to reconnect one to the current path, but nothing happens. The entry for that shot stays in the Missing Photographs group, and the "missing" icon remains on the thumbnail.

Migrate from OAS 10 to Weblogic 11

Hi !!!
I need to migrate from OAS 10 to Weblogic 11, is there some tutorials you could suggets me about it ?
Thanks.

In this forum we commonly cover foreign database to Oracle migrations. To get an answer for your question about migration OAS to Weblogic you should post your question in the weblogic/OAS forum.

OAS's application migrates 4.0.8 to the OAS 10G

I am trying to migrate an application that runs in 4.0.8 to the OAS 10G, and i want to know if you know if some procedure for best practice for do this.

Hi,
What kind of applications are you running?
4.0.8 is quite old. The documented approach would be to go 4.0.8 > 1.0.2.2.2 > 9.0.2.3 > 10.1.2.0.2, which does not sound to tempting to me at least.

Executing an Oracle 9i Client Process from OAS 10g Java Application

Sorry in advance for the long post:
We have a piece of legacy software (Uniface.exe) that contains a good chunk of business rules for an existing system. Uniface client connects to an Oracle 10g database but requires Oracle 9i client libraries. Therefore the default Oracle home for a local machine running Uniface is set to the Oracle 9i client software location.
On the same machine we have OAS 10g (10.1.3.1) running a Java-based middleware product (J2EE). The Java code invokes the Uniface.exe client to run specific business functions. We have in our Java code Runtime.getRuntime().exec(cmd); where cmd is the Uniface.exe.
It appears that when the OAS Java program executes the Uniface.exe it is using the Oracle 10g client libraries from OAS instead of the Oracle 9i client libraries from the local machine's default Oracle home. When we run Uniface.exe from a Windows command prompt it works fine.
We have noticed that when running Uniface.exe from Java OAS uses its own Windows path and environment variables and does not honor the system path. We wrote a Windows bat script to explicitly set the Oracle home and system path to the 9i location and then run Uniface.exe but this doesn't seem to work.
Any ideas?

OAS sets the ORA_NLS33 environment variable to the OAS 10g home location (F:\Oracle\10.1.3.1\OracleAS_1\ocommon\nls\admin\dat). Setting it to my Oracle 9i client location (C:\Oracle\product\9i\ocommon\nls\ADMIN\DATA) appears to have solved the problem.

Migrate P6 Pro Rel7 DB from Oracle 10g Express to SQL server 2008

Please advise the steps needed to migrate my P6 Professional Rel7 (laptop) Oracle 10g Express to P6 Enterprise Rel7 (server) migrating over to SQL server 2008.
I don't want to lose any of my activity codes during the migration.
Thanks in advance for any comments or guidance.

You can use migrate.bat (Media folder/database/installation). Enter the details of the source (oracle db) to destiny (SQL) . The app will migrate everything, the projects, activities, uds, users, filters, layouts, etc.. .

Migrate Sun One application server from One Server to Another

Dear all,
We need to migrate the Sun ONE application from Sun Ultar server to Sun Fire 210. Please share with me if any one done the migration.
Thanks & Regards
Arun

I am sorry. My question was poorly worded after some hours of frustration. What I am really trying to do is develop a base virtual machine snapshot with Sun Web Server Loaded and a base set of applications.
When the need arises, I need to deploy another VM and start it up. There seems to be some issue with the host name of the VM and the administration server, or something. It is my impression that as longs as I have everything contained in one directory like /webserver, I should be able to copy everything to a new machine and start it up. I know I need the listeners listening on all ip addresses and the jdk being used would need to be in that directory as well. Is there anything I am missing here or that I need to watch out for?

Open a pdf file located on Application Server from forms 10g

Dear all,
I want to open a pdf file which is stored in a folder on Application Server.
I have the following codes but could not be able to open the file.
1. host('rundll32 url.dll,FileProtocolHandler C:\REP012.pdf');
in this code I mentioned the path on local machine which is okey.
but the question is that how to open the file which is located in a folder on application server?
the following code don't show and file or error:
host('rundll32 url.dll,FileProtocolHandler /EMS/MANUALS/ACC001.PDF');
This is the file on Application Server not on local machine.
2. web.show_document('//EMS/MANUALS/ACC001.PDF/','_blank');
This give HTTP 404 NOT FOUND error
I think the problem is in path, how to mention the path of my Application Server file?
Regards:
Muhammad Nadeem

Hi,
Did you find a solution to this?
We are running into the same problem where we need to open a file present on the application server (path /opt/webapps/applications/ISL/)
When we try this from the local machine it works (path D:/forms) however it does not work while trying to open it from the application server.

JDEV 1013 and deployment to OAS 10g (9.0.4)

Hi,
I have read that OAS 10g (9.0.4) is not supported by Jdeveloper 1013.
Is that mean that I can't deploy an ADF/JSF application to the OAS 10g (9.0.4)?
Regards,
Cezary

Hi,
yes and no. What it means is that you can't directly deploy from JDeveloper to this Application Server. Building J2EE 1.3 compliant applications and deploy the EAR file to OracleAs 9.0.4 should work. Note that if using ADF I am not so sure if there are issues when deploying the ADF runtime libraries.

Migration of OAS 10g v(9.0.4.1) from one server to another?

Hi,
I would want to know how I can migrate j2ee applications that are deployed in OAS 10g v(9.0.4.1)installed on Sun server to OAS 10g v(9.0.4.1) installed on AIX server at the same OAS 10g version and patch level?
My question is: Can I just copy the application files from the existing instance to new instance or do I have to deploy each application independtly on the new instance?
How I can perform migartion of OAS 10g from one platform to another platform?
Thanks in advance!
GN

Hi GN!
I would think that copying the files will not be enough, as the DCM will not have the information about the deployed applications. Just redeploy them and it should waok as well as on the original server.

Migrating Enterprise Application from WSAD 5.1.2 to eclipse or netbeans

Hi Everybody,
I have a Enterprise Application in WSAD 5.1.2 but I want migrate it to eclipse or netbeans
If anybody has done before please provide me the support on the steps involved
How will I generate required stubs and binding files in eclipse or netbeans?

I belive there is no problems for this change, because the versions are the same for java at least for OaS, for weblogic you should see documentation. I think you can try deploying you app to new environment if you get any noclassdeffound error or something like it then you could have problems for versions.

Manually Migrating from Oracle 10g to 11g

Hello, I'm currently a student in an Oracle DBA class. I'm totally new to the Oracle world.
One of our final assignments concerns upgrading Oracle instances without the use of DBUA.
I've currently got Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 and am trying to upgrade to 11.1.0.7.0
This is all inside of VirtualBox, running Windows Server 2008. I've been using 10g with absolutely no issues for the duration of this class.
I successfully installed 11g, choosing to install the software only and not use dbua.
I changed my environment variables to point towards the 10g installation; ORACLE_HOME, ORACLE_SID, PATH, and LD_LIBRARY_PATH.
Then logged into 10g's SQLPlus and ran utlu111i.sql, which ran successfully. I issued a shutdown immediate and exited SQLPlus.
Changed my environment variables to point towards the 11g home and set ORACLE_SID as the 10g database name. I was able to log into 11g's SQL plus, was told I was connected to an idle instance, which I expected. I issued a startup upgrade command, and then attempted to run catupgrd.sql, but got an error stating that I had to run the script from 11g.
If I don't set the environment variables then when I try to log into 11g's sqlplus, I get an ORA-12560: TNS:protocol adapter error... I've tried reinstalling 11g from scratch, but to no avail. My instructor and I have been emailing back and forth frequently over the past few days but we have not been able to reach a solution, so I thought I would see if I could pick your brains.
Here's all of the terminal output from the process:

Enterprise application conversion problem from WLS 10.3.0 to WLS 10.3.2

Hi all,
I'm posting this just to document a problem I had when converting an Enterprise Application from WLS 10.3.0 across to WLS 10.3.2 environment.

It turns out this was an issue with the META-INF/weblogic-application.xml having duplicate entries for the "webapp.encoding.default" parameter.
This obviously got duplicated when my app was re-imported into the Eclipse OPEP environment for WLS 10.3.2
<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-application xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-application" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/javaee_5.xsd http://xmlns.oracle.com/weblogic/weblogic-application http://xmlns.oracle.com/weblogic/weblogic-application/1.0/weblogic-application.xsd">


<wls:application-param>
<wls:param-name>webapp.encoding.default</wls:param-name>
<wls:param-value>UTF-8</wls:param-value>
</wls:application-param>
<wls:application-param>
<wls:param-name>webapp.encoding.default</wls:param-name>
<wls:param-value>UTF-8</wls:param-value>
</wls:application-param>
</wls:weblogic-application>
Removing the duplicate entry resolved this problem.
I hope this helps anyone else that experiences this issue.
