Migrating Java from OAS to 9iAS

I was able demonstrate a proof of concept java application in the 4.0.8.2 OAS platform. The application retrieved
information from an Informix database and post it to Portal Infranet Billing application. I used Informix JDBC libraries to connect to
Informix database, and Java API calls to connect to the billing application.
So far I have been unsuccessful in doing the same with 9ias. I have installed 9ias and been able to invoke simple
java code.
But when I try to load my test suite, I get a lot of load and resolve errors and I am not sure how to proceed further.
Here are the error messages I get:
F:\common\javatest>loadjava -u scott/tiger -r f:\informix\jdbc\lib\ifxjdbc.jar
ORA-29534: referenced object SCOTT.com/informix/jdbc/IfxUDTInput could not be resolved

For your test case, you must to install the informix JDBC drivers into the oracle JVM first.
But it only will work if this jdbc driver is a mode 4 driver, 100% written in java, like Oracle JDBC thin drivers.

Problem - Migration from OAS 4 to 9ias

We have upgraded the application server from 4 to 9ias and are
now running into problems with calling stored PLSQL procedures.
Here is a code snippet of an example stored proc:
PROCEDURE Test (
num_entries in NUMBER,
name_array in OWA.vc_arr,
value_array in OWA.vc_arr,
reserved in OWA.vc_arr
Basically if I call this procedure (w/o any paramaters) using
the old application server and associated plsql cartridge, it
runs no problem loading the webpage and such. Now when I try to
call the same procedure using the new 9ias mod_plsql, it says
there is an error.
Error output (when connecting using browser)
Test: SIGNATURE (parameter names) MISMATCH
VARIABLES IN FORM NOT IN PROCEDURE:
NON-DEFAULT VARIABLES IN PROCEDURE NOT IN FORM:
NUM_ENTRIES,NAME_ARRAY,VALUE_ARRAY,RESERVED
We have found that if you do not set a default values for any of
the parameters that it comes up with this error. Is this in fact
the case? Do default values have to exist for procedure
variables when using 9ias? If so how would I set the default
values for this test procedure if Number is integer, and the
rest are arrays.
Does anyone know of a migration tool specifially for this
purpose as we are going to update multiple procedures?
Any help would be beneficial.
Dale

Gurus,
I figured it out. I should read the documentation more closely.
Found it in...
For questions about backwards compatibility with OAS, refer
to "Using Flexible Parameters and the Exclamation Mark".
I just have to put a exclamation mark in front of the procedure.
Easy fix

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:

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?

Hi Stoigniew Sztank,
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. It seems you have migrated a J2ee application from OAS 10G to Weblogic 10.3. Please can you list me the steps that you 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

Migrating from OAS to iAS9

Hi!
I'm looking for documents about migrating from OAS 4.0.8.1 (Linux & HP-UX) to iAS9. The document i have found on OTN don't tells me much about how to migrate from JServlet and PL/SQL.
My main questions are:
- how do i migrate my Servlet, which uses many Oracle spezific classes (icx etc.). Are these Classes supported in iAS?
- how i call PL/SQL-Skripts from Servlets now? Is ICX supported?
- can i use my PL/SQL scripts without modifications? I'm using only htp.print
Che
null

a) ICX is not supported from Java. However, ICX is just http library - kind of like java.net.url. So, you should be able to do everything that ICX provided using java.net packages. If not, pl. submit a followup and we can discuss.
b) The way you would call a PLSQL procedure is you would just submit a request thru java.net.url package. The target url of this request would be one that maps to the plsql procedure. You will thus have the response back in a string.
c) You can use your plsql scripts without modifications [at least for what you are doing. there are some minor changes, but they don't impact you.]
The other thing to note is that you cannot runa standalone sql file like you could in OAS. It has to be in the database.

Conversion to 9ias from OAS

We are putting together a migration/conversion strategy for
moving to 9ias from OAS and need to know if we can install 9ias
on the same server as OAS without any issues, then once we have
moved users to this, remove the OAS from the App Server?

I also posted this on the Metalink forum and did get a response
back:
You can certainly install 9ias and OAS on the same box. You need
to be aware that the www listener of OAS uses Port 80 which is
the same port that 9ias tries to use for Apache. You will want
to change the www listener to something else. In addition, it is
not recommended that you use the same database for OAS and 9ias
because they use different pl/sql toolkit. You should use a
different database for 9ias.

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 from OAS 10 to Weblogic 11

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.

Migrate pab from Netscape 4.15 to Sun Java System Messaging Server 6.2

Hi all!
I have installed JES 6.2 and through MoveUser and a little LDAP attribute modify I have migrated all mail/account from Netscape 4.15 to JES.
Now I have to migrate PAB from Netscape Webmail to JES Messenger Express 6.2.
All my PAB stay in o=pab of SunOne Directory Server. How can I migrate this structure to another root (o=pabjes, for instance) for JES Messenger EXpress?
There is any scripts to do that?
Thank you very much
Best Regards
Marco

First, thank for the answer.
I tried,
but Netscape and JES PAB are quite different.
This is an entry Netscape:
dn: cn=170695183, ou=testcomune, o=pab
mail: [email protected]
givenName;lang-it: Plutarco
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
objectClass: pabperson
cn;lang-it: Plutarco Plutone
memberofpab: 117080712
sn;lang-it: Plutone
cn: 170695183
And this is an entry JES:
dn: un=ziopinoc6173be, ou=testcomune, o=pab
mail: [email protected]
un: ziopinoc6173be
givenName: zio
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
objectClass: pabperson
sn: pino
cn: zio pino
As you see, in dn JES appear un instead of cn.
Attributes are little different.
Really, in JES Communication Express I can see also the old entry of pab. But I can't edit them by click to "Display Name": all field appear empty in the opening window.
So, I think two operation are needed:
1) a script that modify attributes from netscape pab to JES pab.
2) when I add a JES account, the pab is added in a tree that is not the netscape pab. The autocreate netscape pab was:
ou=<uid>,o=pab
the autocreate JES pab is:
ou= <tree_of_account_on_his_root>,ou=<uid>,o=pab
To avoid confusion, I would like keep old tree style also for new account without change it by hand in paburi attribute.
Is that possible?
Thank you very much again
Marco

Migrating portal from 10g to 11g

Hi,
We are in the process of upgrading oracle mid tier from 10gAS to OFMW 11g and also migrating it from Solaris to Linux.
With regard the portal migration from OAS 10g to OFMW 11g
1) Is it possible to migrate portal objects from 10g (solaris) to a new install of OFMW portal 11g(linux) directly OR do we have to upgrade the existing OAS 10g to OFMW portal 11g (on Solaris) and then migrate the portal objects to OFMW Portal 11g (on Linux)
I am new to portal migration. Any suggestions and additional details would be appreciated.
Thanks
RB

Migration + upgrade in one shot is do-able, because upgrade will require a sequence of processes but they will be mostly based on repository upgrade, and hence will be transparent to the OS you are using.
However, in practice, the standard rule-of-thumb is that you avoid dealing with multiple layers of complications in a single shot. That means, you break complications in such steps where you could recognize the sources of any later errors/problems you encounter.
hope that helps!

Should I remove Java from my IMac?

Should I remove Java from my iMac? Heard of security problem with Java and wondered if I should delete it,

MadMacs0 wrote:
I've been going entirely on the almost universal statement that installing Lion does not install Java by default. I'm very aware of the fact that older versions of OS X actually rely on the use of Java for some system functions, but I've been told that is no longer the case. If that were so, then there is no need for any Java to be present, yet you say it is there and you aren't the only one who has told me that.
But exactly how much Java is installed by default? Obviously not enough to use it for browsing. In the days of the Java 6 Preferences app, it used to alert you that Java was not installed and offer to do so. What happens with standalone apps like CrashPlan in Lion that require Java, do they have enough, by default, to run?
The only Java component missing in these OSs is the Java Runtime Environment (JRE). Peruse those installations, looking in these directories, and be enlightened:
/Applicatons/Utilities/->Java Preferences.app
/Library/Java/
/Library/Internet Plug-Ins/->JavaAppletPlugin.plugin
/System/Library/CoreServices/->
        Jar Launcher.app
        Java Web Start.app
        JavaVersion.plist
/System/Library/Frameworks->
        JavaFrameEmbedding.framework
        JavaScriptCore.framework
        JavaVM.framework
/System/Library/LaunchAgents/->
com.apple.java.InstallOnDemand.plist
com.apple.java.updateSharing.plist
/System/Library/Java
/System/Library/PrivateFrameworks/->
        JavaApplicationLauncher.framework
        JavaLaunching.framework
to name a few, but probably not all the Java components installed with OS Xs. Then, stop saying Java's not installed, when only the JRE component is missing.
There has been speculation from some that perhaps it migrated from an older system or that Lion was installed on top of the older system. There's also some confusion these days about what actually constitutes a "clean install".
AFAICT, it's speculated wrongly. As for the clean install, I define it to occur when the user wipes the drive, installs the OS, sets up everything, and then installs all 3rd-party software. Then, the installation is clean. If there's any migration involved, then it's not clean. i've not done one for over ten years and my OSs started with 9.2->Jaguar->to the current three.

Migration adapters from OAI 4.1.3 to 9i

Hello,
I am helping a customer who is in the process of upgrading an OAI 4.1.3 hub to 9.0.4 (they're actually going to 10.x, but there is no direct path from 4.1.3 to 10.x). The customer has one or more custom adapters that will need to be migated in the process. When they attempt to start these adapters on there 9.0.4 hub and they get the following errors in the adapter log files.
java.lang.NoSuchMethodError: java.util.Vector: method

Is this due to changes in the adapter sdk's between 4.1.3 and 9.0.4? If so, is anyone aware of a document that describes migrating adapters from the 4.1.3 sdk to the 9.0.4 sdk?

Migrating app from 9.0.5.1 to 10.1.2.0 findAll problem

Hi,
we are migrating our J2EE 1.3 applications from OAS 9.0.4 to 10.1.2.0.2. Thus, we've upgraded JDeveloper from 9.0.5.1 to 10.1.2.0.2 version.
Now, an EJB 2.0, CMP and CMR, application that worked perfectly with version 9.0.5.1 is showing a very strange behaviour when running on 10.1.2.0.2 version.
For instance, we've detected that invocation on findAll method of certain entity bean does not retrieve all the rows in the backend table. In fact, the collection it returns has repeated entity beans.
Any idea on what's going on?
Thanks in advanced.

Ghulam,
The toplink-ejb-jar.xml file is typically created from mapping your entities to the tables in the mapping editor provided in JDeveloper or the standalone workbench utility. It is not a direct 1:1 association with the orion file.
We have provided a migration utility for moving from the orion CMP to the new default CMP (TopLink).

Do you have the problem with all JSP pages, or only a few of them ?
Does it happen in the Embedded OC4J only ?
Could you try to deploy your application in the Standalone OC4J and test it from there ?
I had a similar issue where the Embedded OC4J was unnable to run big JSP pages.
There was no problem with the Standalone OC4J.
Hope this helps,
Didier.
