Oracle Forms 6i client/server against an Oracle 10gR2 database

Hello
We have the following situation:
Oracle Forms6i/Reports6i client server application against an Oracle 8i cost-based database. we want to migrate this application
step 1:
Migrate the database to 10gr2, but do not touch the client application
Go live
step 2:
Migrate the development environment to 6i webforms.
Production environment stays client server.
With this construction we can still create new patches/functionality.
step 3:
Migrate to Forms10gR2 (and reports)
I know Forms 6i is not supported anymore.
My question is on step 1.
When I read NOTE: 338513.1 entitled "Is Forms/Reports 6i Certified To Work Against Oracle Server 10g Rel 1, Rel 2 or 11g?" carefully
it says that Forms 6i is not certified against 10gR2.
On OTN I read several posts that this works ok (assuming you do not use the wrong character set).
I also read on OTN that patch 18 (which is only supported for EBS customers) is certified against 10gR2.
The questions:
- Is Oracle Forms patch 18 certified against an Oracle 10gR2 database? (or only for EBS)
- Is there anybody out there that can confirm that Oracle Forms 6i C/S works against Oracle 10gR2
Regards Erik

Thank you.
Now I found it.
But how do I read that page.
It says:
Client Certifications
OS      Product      Server Status
XP      6.0.8.27.0 Patch 18      N/A      Desupported
Application Tier Certifications
OS      Product      Server      Status
XP      6.0.8.27.0 Patch 18      9.2      Desupported
XP      6.0.8.27.0 Patch 18      10g      Desupported
I read this as follows:
Patch 18 was certified agains a 10g database in a webforms environment.
No client server mentioned and Server 10g , so no 10gR2!
I'm I right?
Regards Erik

I have Windows 7 as the host machine and Oracle 11g R1 client installed on it.
I installed VMWare V5.5 (downloaded from oracle site) and then installed Linux on it as guest OS. I have Oracle database 11g R1 intalled on Linux.
I can ping the Linux server from Windows.
I can also ftp to the Linux server from windows and get the files locally on Windows OS.
The listener and tns files are configured correctly (i assume) on both Linux and Windows.

I am working in client server environment using Oracle 9i + Developer 6i .I have an application in which different users send demands from different computers to his Boss for approval. At Boss computer a form is always open round the clock.
Right now boss have time to time query the form at his computer, to check for any new demand for his approval.
I only facilitate Boss with an indication in the status bar when new demand is send to him for the approval at his computer. I want just Like Yahoo Mail, when new mail is arrived there is always Icon at status bar to show arrival of new mail when we use Yahoo Messenger.

Client server programming

Hi;
I want to learn client server programming on using windows xp for the client and windows server 2003.
I downloaded the 9.2 windows xp database version for the client . What do I need to download for the server? I see that there is a 32 and 64 bit version for the server.
Thanks for your help!

What I was asking is what should I install on the server
the 32 or 64 bit version of oracle?
I want to learn how to write client/server programs using Oracle.
I have a network at home with one computer serving as the client and another has server 2003 on it.
Again Thanks for your help!

Oracle Client 64-bit and Oracle Client 32-bit on the same server

Hi,
I have a Windows 2008 server 64-bit with Oracle Client 64-bit and Oracle Client 32-bit installed on different directories (D:\Oracle and D:\Oracle32)
Is it possible to define for certain applications to use the TNSNAMES entry from the 64-bit Oracle Client
and for other applications to use the TNSNAMES entry from the 32-bit Oracle Client
Once I installed the Oracle Client 32-bit (Oracle Client 64-bit version was already installed) and restarted the server I performed a TNSPING and it defaulted to the Oracle Client 32-bit installation path
Thanks,
Barry

Hello,
When you install a new client on a server, it will update the PATH variable, and add the ORACLE_HOME\bin path to it, at the first place. That explains why the tnsping use the last installed ORACLE_HOME.
What you can do if you want only to change the default path to the tnsnames is to set the environment variable TNS_ADMIN to the path where the tnsnames you want to use is located. You can modify this variable in your application if you want to use another tnsnames.
If you want switch from 32 bits to 64 bits client, then you have to modify the PATH variable.
Hope this will help.
Best regards,
Sylvie

How can i get jdbc2.0 compatible driver for my oracle 8.1.5 client/server

Hi ,
I am looking for a driver that is jdbc2.0 compatible.Apaprently the oci and thin drvers that are shipped with oracle8.1.5 do no support scrollable and updateable resultsets. Can i download the oracle8.1.6 jdbc2.0 compatible drivers and use them with my oracle8.1.5 client/server. if so how do i install it?
Please let me know ASAP!!
It is relly frustrating to find a compatibler driver for the older versions since oracle does'nt provide them
poornima

Yes. For OCI driver, you will also have to have Oracle 8.1.6 client installed as well. http://technet.oracle.com/tech/java/sqlj_jdbc/htdocs/jdbc_faq.htm#_1_

Will Oracle 8I release 3 Server work with Oracle 9I Client?

My company wrote some software for DBing imagery tags and such. this was originally done for win2k. They company now needs to upgrade to winXP systems in order to keep there maintenance contracts. long story short can i continue to use the DB 8 server with the DB 9 Client? on a side note i tried installing 8I client on XP and ran into some problems.
i found the fix to get the installer started but then i i just crash to desktop halfway through the install. any and all help would be greatly appreciated.

That WAS a supported configuration ('was', because both components are meanwhile desupported), but it worked in the past from a technical point of view. Details on metalink:

Oracle 9i Forms in Client/Server Mode (Updates in Technical FAQ)

Hi All,
I'm doing an investigation for porting to Oracle Forms 9i and I've found the answers in Oracle 9i Forms Technical FAQ of February 2003. But since it's been more than three and a half years, I would like to know if the following information in the FAQ still holds?
Upgrading to 9i
What versions of Forms can I upgrade to Oracle9i Forms?
Only Forms 6.0 and Forms 6i are supported for direct upgrade to Oracle9i Forms. Older versions of Forms should be upgraded to Forms 6i first.
Can I run Client Server or Character Mode applications in Oracle9i Forms?
No. Oracle9i Forms only supports Web deployment. Applications that need to be run in Client Server or Character Mode should remain in Forms 6i. Forms 6i will be supported until December 31st, 2004, or December 31st, 2007 with Extended Support for customers who wish to maintain such applications.
What changes will I have to make to my application before upgrading?
Many Client Server and Character Mode features have been removed from the Forms product for 9i. The removed features mainly relate to features that where only maintained in Forms 6i for the purpose of backwards compatibility. A detailed list of all of the obsolete features can be found on OTN (/products/forms/pdf/featuresobsolescence.pdf)
Is there an easy way to find out if my modules use obsolete features?
Yes. Oracle supply a separate utility with the Oracle9i Forms distribution "f90plsqlconv". This is a utility which will scan your files for obsolete usages and correct them where applicable. It will also alert you to any changes you may have to make manually.

As far as I know it still holds: Forms9i isn't changed since then.
What I don't see in the FAQs is if you move form client/server to the web that you must be aware that the forms are running on the application server instead of the client PC. So calls to TEXT_IO and HOST etc are also executed on the appserver. You should review those calls and decide were you want to have them executed...(use webutil if you want to keep the execution on the client)

Can we run oracle Forms 5 Application with 10G in Client/Server?

Hi All,
Can we run oracle Forms 5 Application with 10G in Client/Server
Mode?
Regards
Gaurav

In theory you can run it 2 tier - which means that you have the client (the machine the user is sitting at) being the same machine in which the forms application server is running. So yes. But specifically, we don't support a client server runtime anymore. 6i was the last version.
With 10g you will be running through a browser.

WARNING - Oracle intends to desupport Forms client server mode

When Forms 6i becomes desupported you will have to move to Forms 9i. Forms 9i runtime can only be run in web mode from a web browser. You will not be able to run client-server forms in native operating systems such as Windows or Unix. The forms will essentially run on the application server with Java applets to being sent to your web browser. Links to third party products will no longer work with host commands executing on your local machine. You will have to include Java code to make local commands work.
The transition from Forms 6i client-server to Forms 9i web mode will be one of the most painful upgrades Oracle has ever inflicted on its customers.
Essentially, Oracle is trying to palm us off with running forms from web browsers whether we or our customers like it or not. Java seems to be creeping in. I suspect Developer will eventually turn into JDeveloper, as they will not want to support two products. Easy one line statements and built-ins will be replaced by hundreds of lines of Java nonsense. Developer will move from a 4GL RAD environment to a cumbersome bloated 3GL Java environment.
You can stop this happening if you want to keep you customers happy by:
1. Sending Oracle enhancement requests to allow Forms 9i to run in native client-server mode.
2. Complaining to your Oracle sales contact.
3. Asking difficult questions at Oracle user groups.

Duncan et al.,
I've been wondering why exactly a Forms9i app. needs to run in a web page? Why could the applet not be deployed in a more "standalone" fashion, i.e., an independent application window. This would at least offer the appearance of a native application, complete with the new Java look-and-feel.
If Oracle really wanted make their customers happy, they would then take the next step and come up with a way to embed OC4J into a client-side deployment executable, which would then effectively allow for a 2-tier client-server architecture.
It seems to me that 2-tier/3-tier each have their place in the world, depending on the situation. In the extreme "2-tier" example would be an application that is to be deployed on a single client workstation. It would be hard to argue that a separate application server ought to be used. On the other extreme, anybody who has tried to manage the deployment--and upgrade--of a large number of Forms clients is very attracted to the prospect of only having to maintain and upgrade a few application servers.
I agree with the direction of the product as far as replacing Toolkit2 and the native runtime with the JRE. The advantage of on-demand updating of application code is compelling. The capability of moving application logic to the middle tier is extremely useful. Platform independence is now done using the "universal" JRE instead of TK2.
If the product could maintain the client-side processing capability--without resorting to Javabeans--it would be just that much stronger. As an application architect, I want to be able to design the application to allocate the work where it makes the most sense, either on the client, the application server, or the database server.
How hard would it be to put this client-side processing capability back into the product?

Bruce MacDonald

CORBA - Oracle DBMS acting as Client in a relation Client - Server

Hi,
I'de like to invoke some services in an Transaction Server from my Oracle 8i Database (8.1.6) wich is in another machine. Is this possible in Oracle, and if so, are there any resources explaining how can i achieve this?
Note that the transaction in the database must wait for the confirmation of the success of the external services ( java 1.2 ).
Thanks in advance,

I have created a DSN in a web server (a Public IP machine) that is mapped to a Oracle DB.
In my Excel using VBA coding, with the help of RDO object I will call the DSN in the Web server using the connection string like "DSN=ORS;UID=SDATA;PWD=SDATA;"
This is working fine and in this case the client machine doesn't need Oracle client to be installed or any TNS entry.
The user can run the Excel report by clicking a button and the click event connects the DSN in the web server (through its URL) and routes to the mapped DB and fetches the quried data.
Please note that the above DSN is created based on Microsoft ODBC for Oracle driver.
But the issue is using the Microsoft ODBC for Oracle driver I couldnt call the SP with Ref Cursor.
When I searched in Internet I came to know using the provider oraoledb.oracle we can call SP that uses REF CURSOR.
Now my question is what is the driver name that I can use to create a DSN to make use of the provider oraoledb.oracle for calling the SP with REF CURSOR from Excel VBA coding ?
Appreciate your prompt reply.
Thanks & Regards,
