Oracle Developer 10g works on Oracle Dtabase 21c XE?

Question

I want to connect my oracle database 21c xe with Oracle Developer 10g (forms/reports)?

Answer 1

I can't find any reference on the Internet (My Oracle Support included). The closest information I managed to find is about Forms 10g on database 19c.

Michael Ferrante (from Oracle) said:

Forms 10.1.2 has been out of support for over 10 years, long before Database 19 was even a "thing". This is not a supported configuration that I would consider for any production environment. That said, some people have claimed to get things working. So, it may be technically possible, although I personally would not do it nor would I recommend it.

If you choose to ignore my warning and recommendation, I will say that if you plan to do it ensure that you are at least running the latest patched version of Forms 10.1 (10.1.2.3 - patch ID 5983622) and have installed the latest/last DB 10.1.0.5 client patch (4505133) into this home. As always, create a backup of the home before attempting to apply any patches. Following this guidance should help to reduce the risk of having problems.

Therefore, as 21c (XE) is even newer than 19c, you might - or might not - make it work. There's no guarantee that it will.
