Oracle Forms Developer 10g crashes while trying to open forms

Hi guys

I had couple of posts addressing the same issue

  1. https://windows7bugs.wordpress.com/2010/03/20/windows-7-oracle-developer-10g-crash-work-around/
  2. https://windows7bugs.wordpress.com/2011/05/21/oracle-developer-10g-10-1-2-0-2-crash-on-windows-7-while-opening-forms-modules/

and one of my observations was strictly around the connection to database. I found forms those make calls to database level packages/procedures/functions crashing the developer when they are opened while no established connection with database exists.

Recently I was contacted by one of the visitors asking for help to resolve his issues with the crashes experienced while opening forms those were developed by someone else. We had a short TeamViewer session I realized that the issues were more than mere database connection specific. Then I remembered fixing few of such issues which were caused by missing table columns, packages/procedures/functions at the database level.

I located one of the backups and tried to open a form which I was extremely sure of crashing the developer due to missing objects at database level. All I remembered that I have added additional columns to a table that was in the form and a modified database level procedure, which were missing from freshly cloned database.

Unless I open this particular form, I will not able to re-create the objects and continue with the development as I don’t have any logging for the changes I have made to the form/tables/other objects during the development.

Then I remembered that Developer 6i hardly ever crashed due to missing objects, instead it did warn. As I had a classic domain setup using Weblogic 12c 12.2.1.3 recently with forms and reports developers, I decided to open this problematic forms module with the 12c forms developer.

That was the solution.

(The best thing about Weblogic 12c Forms is, you can opt for a standalone installation of the developer, avoiding all complexities around setting up the entire Weblogic infrastructure. Oracle have so much crap in their decision making team, having weird ideas like forcing the developers to setup an entire Weblogic infrastructure for mere development? duh!)

 

Now, if you are having such a situation, follow the below instructions:

  1. MAKE many copies OF YOUR TROUBLESOME FORM, KEEP THEM IN DIFFERENT PLACES
  2. Open Forms developer 12c, establish connection to database
  3. Open a copy of the form that crashes 10g developer
  4. If the form open (it should in case if it was crashing due to missing objects!), compile all objects (CTRL+SHIFT+T). This should start throwing errors about missing columns and other objects.
  5. Alter your tables, create missing objects and open your form using Developer 10g

That’s it. You must be glad to have it fixed.

Hope this helps few Oracle developers who are mainly developing for Oracle Applications R12 using Developer 10g Suite.
