Dear Sir

I have created oracle forms&reports in 5i which is in oracle 8i database. I need to migrate the forms&reports as well as the database to oracle 11g andI need to run these in a 64 bit Linux 5.6. I kindly request you to please tell me the steps that i need to follow for migrating my 32bit(windows os made) forms and reports to Linux5.6 64 bit?

You're moving to a web based environment so the first steps are:
- get your 11g database up and running.
- get your Weblogic Server (Oracle application server) up and running. You will need to compile all your forms/reports on this server.
- install Oracle Fusion Middleware 11g ( I think that is what Oracle calls it nowadays ), your Forms and Reports developer tools, on your client.

Once you've got that ready, you can start to migrate. But that's easier said than done. There are quite a few loopholes. For instance: code in PRE-FORM triggers might crash your Forms runtime process so you may want to clean your PRE-FORM as much as possible.

Good luck and feel free to come back if you have specific questions!

Forget 32-bit/64-bit. That's not an issue here. Did you encounter problems?

I can give you some tips:
- Make sure you use proper casing (Initcap, UPPER, lower) in the names of your forms and libraries (both OLB and PLL) or the Linux compiler will fail to find the references.
- WHEN-NEW-FORM-INSTANCE triggers on block/item level won't work in 11g.
- PRE-FORM triggers (but I've mentioned that already in my previous reply).
- Be careful when using "synchronize": it causes a roundtrip from the client java applet to the application server. This might impact performance.

It's hard to tell because a lot of issues are specific to a particular version and might have been corrected now. Just do what we did:
- try to compile the form on your client.
- copy the FMB to the AS (weblogic server)
- compile the FMB on the Linux server
- test

Forget 32bit/64bit. I said that before. You should be able to copy/move FMB files (which you have checked on your client 11g!) onto the Linux without any problem. Forms Compiler (whether it is 32 or 64 bit) should know how to handle it. Does that answer your question?

Hi MHE,

I had a previous experience in deploying forms and Reports on 64 bit box. There were few issues with 2 DLL's while running the reports.

That is why I am requesting if any such issues are there in migrating 32 bit windows based application into 64 bit Linux environment.

Further OLE components may cause another issue. So I need a complete list of such issues. If any such doc is available from oracle kindly share the same.

Thanks and Regards
Rijo

DLL's? On a Linux box? I have no experience on migrating reports but isn't it just like Forms? I mean: copy the RDF files (not the precompiled REP files) to the Linux box and compile? As for OLE, you are right. You should move to Webutil or CLIENT_OLE (CLIENT_OLE2?). But perhaps Metalink can help out here.

I'm sorry but without a specific question, I can't give you a specific answer. I know that Forms 11g no longer supports OS-specific item types like VBX, OLE, OCX, ... Perhaps this document can help?

I still have difficulties for the DLL problems you had because, well, Linux hasn't got the slightest idea what DLL's are.
