I've had Forms V9.0.4 operate against V7, V8, 8i, V9 R1 & V9 R2 DBs.
Why should the forms care about the version of the DB as long as they successfully make a Sql*Net connection?
You did RECOMPILE the Forms with the 10g compiler ,didn't you;
before you tried to serve them with the 10g server?
I have tried that.
I installed 9i in c:\DevSuiteHome and 10g Developer in C:\dev10g
I am able to connect to sql plus and work with 9i database.
Forms 10g is also opening, but when I try to connect in Forms 10g, I get TNS Listener error.
I think I am quite close to solving my problem. Can you help me on this.
I have two oracle homes c:\DevSuiteHome and C:\dev10g.
You've made two posts and STILL have NEVER specified the EXACT and ACTUAL error message(s).
I am NOT a mind reader.
My crystal ball is broken.
There can be many, many, many reasons why "it does not work".
Without a clue as to the source of the failure, You're On Your Own (YOYO)!
Keep in mind that by having two ORACLE_HOME trees
two TNSNAMES.ORA files exist and are individually used.
