PITSS has performed numerous Oracle Forms installations. We have seen numerous Forms 11g installation errors reported by our customers. We have compiled a list of some common Forms 11g installation errors:

When installing Forms 11g services, after installing WebLogic 11g server, I get an error ‘Oracle Home OH123214 already exists in ‘%WEBLOGIC_HOME%\inventory’, but there isn’t an installation in that directory. This error occurs before anything from Forms 11g can be installed.

This is most likely caused by old existing files, an installation was probably previously installed and Oracle Deinstaller did not cleanup the necessary registry entries and files. To fix the problem, do the following:

  1. Copy the OH[some number] from the error message.
  2. Verify that this OH is not in your start up programs and that it is indeed uninstalled.
  3. Search through your registry for the OH[some number], delete all entries.
  4. Go to C:\Program Files\Oracle\Inventory\ContentsXML, open inventory.xml in a rich text editor such as WordPad.
  5. If you see the OH[some number] from your error message in a ‘home’ entry, remove it from the configuration file.
  6. Try running the installation process again and it should work. If not, go through the previous steps again, but when looking through the registry, go to ‘HKEY>Local Machine> Software >Oracle’ and remove any OH[some number] folders/entries that are no longer installed.

When Installing Forms 11g services, I get an error during the configuration process, saying ‘Error Creating Domain’.

This is because the WebLogic Node Manager is running and currently using Port 5556. Shut down the NodeManager either by WebLogic Scripting Tool (WLST) or by killing the process in task manager (‘beasc.exe’).

When Installing Forms 11g services, during the configuration process, the ‘Creating Domain’ appears to hang, no errors are returned but after multiple tries of 30 – 60 minutes on that particular step, the installation stays at the step.

This could be a variety of issues. One could be that the computer of which PITSS.CON is being installed on is low on memory. It is recommended that the machine have 8GB but at least 4GB of RAM, and at least 4GB of virtual memory.

Secondly, during this process open the task manager and look for the java executables that are running in the background under the ‘Processes’ tab. By then the java process should be 200 – 400 MB big. If it is under 200, there is likely low memory.

Thirdly, check your PATH environment variables. They should not contain any parentheses such as “Program Files (x86)”. Also, it has been known where having spaces in the PATH can also cause this problem. Using the format “DIRECT~1” to replace a path with a space can work. Example: Change C:\Program Files to C:\PROGRA~1 in the PATH.
