Oracle Forms 6i(32-bit) => Oracle database 10g R2 Windows 2008 R2 64-bit)

Posted on 2010-08-24

Last Modified: 2013-12-19

We have Oracle database 10g R2 installed on a Microsoft Windows 2008 R2 (64-bit) (SERVER1)

We have Oracle Forms 6i (patch 4a) installed on a Microsoft Windows XP Professional (32-bit) (SERVER2)

I am not able to connect from SERVER2 to SERVER1, either through SQLPLUS or FORMS BUILDER.

Its giving some forms dialog box error.

My TNSNAMES and other connections are fine.

When I do a TNSPING80 SERVER1_DB  its successful.

Is it because forms 6i (32-bit) cannot connect to a 64-bit database on a 64-bit OS ?

There should be no problem between the operating systems.

What error are you getting?

FYI: tnsping doesn't actually talk to the database.  It just asks the listener if it knows about the database.

Depending how you have things swt up, tnsping will work if the database is down.

It seems that you have problem with your installation of developer 6i,

can you connect to other database (local on your xp SERVER2)
if you run form builder can it connect to database and if not what is the error message you got.

Yes I have been using this same 6i installation to connect to another Oracle database (32-bit) all these years and its fine.

I probably should have thought about it a little more before I said there should be no problem...  I forgot how old 6i is.

What is the version of the other Oracle database?

The version of sql*plus is 8.0.  Man that's old.  Oracle 8.x sqlplus does not connect to 10g.

Check out Metalink Note: 338513.1
It states forms 6i patchset 16 or patchset 17 was certified against 10gR1.  It also states it will NEVER be certified above 10gR1.

See if you can get hold of either of those patchsets.  If it connects to 10gR1, it 'should' connect to 10gR2 even if not certified.

Came across this for 10g XE.  It might work?

I did install patchset 17 yesterday and had no luck.

We were able to connect with 8.0.6 sqlplus (patchset 4a) with 10g database 32-bit database all these years.

Only issue now I have is connecting to Oracle database 10g (64-bit) on windows 2008 R2 (64-bit OS)

Are both the 10g databases the same release (10gR1 or 10gR2)?

>>We were able to connect with 8.0.6 sqlplus

Interesting. That isn't supposed to work.  Who knew...

I can't imagine it's a 32-Bit/64-Bit only issue but stranger things have happened.

I also wouldn't expect the characterset having anything to do with it but did you check out the link I posted above?  

Can you verify the characterset information between the two databases are the same.

Awesome !!!!!!!!!!!!!!!!!!!!!!!!

When I changed the character set on the 10g ( 64-bit database , it worked.

Now I am able to connect from Oracle forms/reports / sqlplus (8.0.6)

Thanks "slightwv"  for your help
