I have been using Forms 6 against our production (UNIX based) database for years now. For querying and routine "stuff" I use TOAD.

Recently I wanted to do some standalone development, so I downloaded Oracle 10g XE. It works great. TOAD connects to it just fine.

What I would like to do now, and am having problems doing, is connecting Forms to the XE database. I'd like to get a setup where Forms will work with both databases.

I just can't get Forms to see the XE database. I get the error:
ORA-12154: TNS:could not resolve service name.

I've made sure that my tnsnames.ora files contain the XE entries. I've moved the listener.ora that is found in XE's "admin" folder to my orant "admin" folder and still have no luck.

Does anyone have any ideas?

Although people still use Forms 6i, this product is obsolete; even its extended support ended. This, of course, doesn't mean that you can't make this combination (Forms 6i + database 10g XE) work, but there's also no guarantee that you'll really manage to set up a stable environment.

As you've already installed 10g XE, perhaps you could move on to Application Express (APEX) (instead of Forms 6i).

Our organization is still using Forms 6i. We are preparing for an upward migration, but for the time being, everything needs to be 6i. So I am stuck, at least for the time being, with it and still would like to get it to work with XE.

This moving of files is dumb. You need to modify your EXISTING configuration, not overwrite it. LOOK at what is in the existing 'admin' area and what is in the new database 'admin' area and copy the NEW definitions to the existing definitions.

Search this forum for 'tns_admin' and start from there.

Thank you for the advice David. I'll check the forums for "tns_admin". But perhaps I wasn't making myself clear. I believe I have already done what you recommend when you recommend that the existing configuration should be modified.

I had taken the contents of the two existing configuration files (tnsnames.ora) and combined them into one. I have not overwritten any files. I did move one file (listener.ora) from the XE admin folder to my pre-existing admin folder simply because it did not exist there and was hoping it would make some sort of difference. It did not.

Now... Off to do another forum search...

Amazing how little time it takes to solve a problem when you have that last little bit of information. Using "tns_admin" works great.

Everything I had done was good up to a point. Once I set that variable it all fell into place.

Thank you David.
