Migration of large application from JDK1.4 to 1.6

Hi,
I want to migrate some large application code base's from jdk1.4 to jdk1.6. Need some help regarding this. Please let me know the following as mentioned below :
1. Is there any tool/s available that can be used for this migration (Because manually it is very difficult for a application with almost 15,000 java files and 15 * 10^6 KLOC within a limited time frame).
2. Steps that should be followed in such cases.
3, If any tool is not available for such activity what are the salient points that are needed to be considered while migrating.
Thanks in advance

What is it that you think needs to be 'migrated'?
Most applications will run just fine using 1.6 - it is compatible with 1.4 already.
You need to conduct your own tests using 1.6 to see if there are any problems/issues with your app.

Problems After shifting swing application from jdk1.3 to 1.4

hi,
i have shifted my Swing application from jdk1.3 to 1.4, some component settings changed in j2se1.4. are listed below
1). i have added JComboBox to JPanel using BoxLayout, in jdk1.3 it is normal where as in 1.4 comboBox height is increased to panel height.
Sample code
(in a Panel)
     setLayout(new BoxLayout(this, BoxLayout.X_AXIS));
add(getYearComboBox());
     add(getMonthNameComboBox());
     add(getDayOfMonthComboBox());
2). in jdk1.3 the icon which is set to JFrame is visible in the JOptioPane.showConfirmationDialog() also, but in 1.4 the icon is not visible in conformation dialog box.
Sample Code
in a JFrame's constructor
public OptionPaneTest()
ImageIcon icon = new ImageIcon("icon.gif");
setIconImage(icon.getImage());
setSize(250,100);
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent e) {
                    System.exit(0);
setVisible(true);
JOptionPane.showMessageDialog(this,"hai", "Hai",JOptionPane.WARNING_MESSAGE);
3). the Labels added to the panel or frame are displaying in light blue color with jdk1.3 and the same label displaying in black with j2se1.3
Sample Code
in a JPanel
setLayout(new BorderLayout(20, 20));
add(new JLabel("Testing Label Color"), BorderLayout.CENTER);
please send solution to any or all.
thanks in advance,

How can i migrate a single application from my old macbook to my new macbook

Can I migrate only single applications or files using the migration assistant? how?

I feel I've explained plenty what you must do but you aren't getting it.
All music on your old iPhone should be in your iTunes library on your computer. Transfer the music from your iTunes library on your computer to your new iPhone in the same way it was transferred from your iTunes library to your old iPhone - via the iTunes sync/transfer process.
Since you prefer the manual way, you must manually drag and drop the same 377 songs from your iTunes library to your new iPhone - in the same way the 377 songs were manually transferred from your iTunes library to your old iPhone.
Or you can sync which provides more options overall. Create an iTunes playlist for the 377 songs. Select Sync Music under the Music tab for your iPhone sync preferences with iTunes and choose selected playlists, artists, albums, and genres. Select the iTunes playlist below that includes the 377 songs followed by a sync.

Migration of Planning Applications from 9.2 to 11.1.12

Hi All,
How to see the installed Planning version (applications, and all objects)?
Actually We were trying to migrate planning applications from 9.2 ( planning web and 1.5.0.0034 is desktop) to 11.1.1.2 version. I have followed steps as follows
1) Create the users as per earlier planning application in SS (optional assume)...I didn't do.
2) Creating Database(DB) for New Planning application
3) Create Data source connection to the created DB for creating application
4) Create the application in planning in accordance with outline of given backup files
5) Restore DB.bak file from backup into newly created DB
6) Restart planning service
7) Open Planning web application, after login you can see migrate option there...click it
But when I click that migrate button, I wondered to see that it is throwing the following error....
"The application Version is invalid. Existing version : 4.1.1, Expecting version 11.1.1.2"
Please advise...
Appreciate your responses on the same.
Thank you

We have tried this but are unable to log in to the v11 planning app after copying the 9.x schema. updatuserd.cmd fails with a comment in the log about v9/v11 version mismatch.
In v9, our users are via an LDAP server and in v11, they will be via AD so the users can't possibly match anyway.
We are wondering how it is possible to migreate our v9 Planning apps to v11 now ...

Rahul,
As John pointed out, copyapp may be available between different versions of planning but is not compatible between different versions of the software. When a copyapp command runs, it connects to shared services, planning and essbase data sources and basically performs an export and import of data. It works on the premise that structure for export is same as structure for import. However, the underlying architecture for shared services (moving away from openldap) and planning tables, essbase (security outside .sec file) has changed and there you cannot just export and import between different versions of software.

Migration of web application from 8.1 to 9.2

Can anybody tell me how to migrate a web application (ear, war archive) from version 8.1 to 9.2. I believe that the application can simply be transferred and deployed in 9.2 from 8.1 and it works well. But if it doesnt work, do i need to change anything in the desciptor files or anything.
Thank you

Well you could still use servicegen ... I'll try to look into this some more.

Migrating third-party applications from 4.x to 5.x

Hi all.
My customer wants to migrate its CUCM 4.1.3 to 5.1.3. He has some third-party applications that read CDR's and process the information. I've heard that in version 5.x it's not possible to directly access to CDR in order to obtain the required data but you have to use the CAR tool. Is this true? Or you can use Informix commands via a third-party application to access the information at CDR's?
Thanks for your help.

The CDR records are stored in flat files and then FTPd or SFTPd to your choice of up to 3 billing servers.If you upgrade from Cisco Unified CallManager 4.x, Cisco Unified CallManager saves the CDRs in the CAR database to CSV files. The Data Migration Tool uses these CSV files to upgrade the CAR database. The system stores the CSV files in /common/download/windows/car. The system stores the pregenerated reports in /common/download/windows/pregenerated.
Because Cisco Unified CallManager 5.x does not use a CDR database to store CDR records as in previous releases, the CDR data does not migrate to the Cisco Unified CallManager 5.x system.

Steps to migrate Hyperion Planning application from 9.2.0 to new 9.3.1 env

We currently have 9.2.0 Hyperion planning installed in a windows env. We are planning to setup a new Hyperion planning env on a totally new hardware upgraded env. Would be appreciate if some can outline steps invloved to migrate Hyperion Planning apps, forms, BR ect from 9.2.0 to the newly setip 9.3.1 env. Is there any documentation, URL's to do the above. Any help would be greatly appreciated. Any issue to look out for, setbacks details would be helpful.
Thanks..

Hi,
One way of doing it would be :-
Create a new database for your planning application 9.3.1
Create a datasource to the database
Create a fresh planning application on version 9.3.1 make sure the admin is the same name as your old 9.2 planning app
Go into the database tables for the planning app and look at table HSP_USERS, store the SID value against user 50001
Go into the database planning system tables and HSPSYS_APPLICATION, clear out the version field for the application you have created
Stop Planning
Restore the 9.2 planning application database over the one created in the first step
Go into the HSP_USERS table and update the SID for user id 50001
Start planning
Go to planning web and you should see your application when you try and log in it should take you to a migrate screen.
If you are requiring to migrate users as well, you will have to make sure you create them in Shared Services and then use the updateusers utility in the planning bin directory.
Or you could try using the copy app utility though I don't believe it is the best utility about and not sure how it handles between different versions(http://download.oracle.com/docs/cd/E10530_01/doc/epm.931/html_hp_admin/ch09s01.html)

Migrating Hyperion Planning Applications from 11.1.2.2(old server) to 11.1.2.3(Development Server)

HI All,
I have 1 PSPB, 1 PFP and one OPEX Planning Applications in 11.1.2.2 old server which we are planning to move these apps into new development server having Hyperion11.1.2.3v installed. I have gone thru few documents but im still in dilemma that can we go ahead with LCM backup and export apps in old server thru LCM backup and place it in File system area of new development server like we do usually or do we need to upgrade the 11.1.2.2 old server with maintenance release and then taking LCM backup of that upgraded applications only, we can migrate in new server having 11.1.2.3?
Please guide
Thanks

A)Created a planning shell application with the same name as that of 11.1.2.2 planning application
B)Backup 11.1.2.2 planning schema
c)Restore the old schema 11.1.2.2 to new environment 11.1.2.3
D)update the SID ,Only if the userid (Default :admin) is different for 11.1.2.3 version
E)Restart the planning services
or make use of Planning Upgrade wizard
A)Logon to workspace (11.1.2.2)under Administer-> Classic Application Administration-> Planning Administration
B)Go to Classic Application Wizard ->Upgrade Wizard
or also try with the lcm way.
Thanks,

Migration of an application from db express edition to html db!!!

Hi,
I created an application using Oracle DB Express Edition (on Linux), I exported it and I want to import it to html db 1.5.1.00.11, I installed html db and oracle http server using the companion cd 10g for Solaris. When I try to install the application (file.sql), it shows me an error:
1 error has occurredNOT COMPATIBLE (Your export may contain calls not supported by your application version.)
What Can I do??
Do I have to install the Application Express 2.0 running the script in the Database? or it is no possible to migrate an application made with xe to html db??
I'll be waiting for a possible solution.
Thanks in advance.

Elizabeth,
HTML DB is upgraded automatically when you install Application Express (HTML DB) 2.0. There additional configuration steps required. All the details you need are in the Installation Guide:

HTML issues in Migration of Existing Application from Apex 2.0 to 2.2

hi
In my Existing Application of 2.0, iam taking some HTML formatted values into hidden fields like :P35_NOTIFICATION_BODY (Contains data like with HTML syntax<b><font color ="red"><notif Contents></font></b> ) etc.
and displaying that data into HTML region like html Header: &P35_NOTIFICATION_BODY.
for the quick view of the received user's notifications and its working fine in 2.0 version and data is showing correctly with the html formatting.
but when i trying to run that application into 2.2 version, i found that the html region showing data with the HTML expressions instead of formatted HTML.means its not formatting the HTML contents and showing HTML Expressions direclty.
Please suggest me why is that different come and what is the reason behind this.

Hello,
There were some changes in behavior between version 2.0 and 2.2 regarding the issue you are describing. I believe the following thread can clears things up for you - Re: Computed Region TItles being Escaped in Apex 2.2

Info : Migrating Apex Application from Non-SSO to SSO environment

Hi All,
This post is to share my experience while working on APEX. This may be useful to some apex developer.
If we migrate an apex application from a non-sso (i.e. http) to sso (i.e. https) environment, the flash chart doesn't work.
I found that in the source of a Flash Chart region, we use #HOST# variable to locate the swf file. The environment variable takes the correct path but with "http" as prefix. But to access application pages "https" is used. Because of which, the swf file couldn't be located by the application.
Work-around Solution : If I hard code the value i.e. the application path having "https" replacing #HOST# variable then the flash chart works fine. I couldn't found a way by which the #HOST# parameter value can be updated to take "https".
The same environment host other non-sso applications as well.
Any comments on this are welcomed.
Regards,
Mangal

Hi Dirk,
Thanks for the reply.
As I mentioned earlier, by Non-SSO I mean "http" and by SSO I mean "https". This is because, before migration the application was accessible using "http" and now we have to use "https" alongwith SSO to access the application. I only want to highlight the Flash Chart issue with this migration.
The problem doesn't solves with your solution as I am getting correct instance/environment name with #HOST# but prefixed with "http" and not "https". Hence the application won't be able to locate the required swf file.
Even the workaround I mentioned is only feasible, if an application has only few Flash Charts. However, if there are large no. of Flash charts in an application, then it would be a tedious task to update all flash chart source either by an application item (as you mentioned in your post) or hard coding the path itself. Also, every new Flash Chart source needs to be updated by a developer to fix this.
A better solution is required by which the Flash chart source is not touched and the #HOST# variable for the application is updated to take the "https" prefixed to the swf file path.
Regards,
Mangal

Hello TomB,
Could you elaborate a bit on your explanation? I'm having the same problem as talk2srujan. I currently have an application which works fine in weblogic81 and, when migrated to weblogic103, fails at deployment time. The error I get is: unable to find EndPointFinder for tibjmsnaming://host:port
We didn't have to register any foreign servers in weblogic81, should I do this in weblogic103?
Could you also give a pointer to the known bug you mentioned?
Thanks in advance,

Problems while migrating PDK applications from Portal 7.1 to Portal 7.3

Hi All,
I am facing a problem while migrating a PDK application from Portal 7.1 to Portal 7.3.
Since Portal 7.3 doesnt support PAR files any more it provided with a tool to convert the PAR to an EAR file and deploy the resultant EAR to the new portal.
I converted the PAR into EAR and deployed the file but the application is not executing. When I looked into the log files i found the following exception. The application is not able to identify the tag "documentBody". I checked the protalapp.xml and the "SharingReference" is properly maintained in the file but the error message suggests that its not able to fine the reference to the tagLib uri maintained in the portalapp.xml
Now my question is why is it not able to obtain a reference to the taglib? Did any one face similar problem previously. Can you please provide me with any document for migrating / developing PDK application for Portal 7.3

Hi Amit,
Thanks for your reply. I could see some progress after "thoroughly" going through those links. Thanks a lot (gave points too )
Now I am facing another problem. The application did deploy successfully but with a warning. When i checked the warning it says that the deployment was successful but can not be started.
The log file has the following error message.

I dont understand why is SAPPORTAL/com.sapportals.htmlb is not available. As per my understanding it is some thing that should be available with the portal server by default.
Any hints from any one?
