At least once per ninety days, I have at least one client who gets the ORA-12541 Error Message while using Ellucian Banner Navigation on a Windows PC. This usually happens because the client did not heed my warning to disable auto-updates as it will, unfortunately, overwrite their needed jvm.dll files.
Temporary Fix
A temporary fix is to locate the jvm.dll files in the Oracle folder in the Program Files and Program Files (x86) and correct them to the necessary version that supports the Banner Navigation. Be warned that Java updates will eventually overwrite the files, and you will have to make another trip to fix the issue, which will upset a paying client.
Permanent Fix
To correct the issue permanently, first disable Java’s auto-updates. I would also disable automatic Windows updates, as these work in the background and often slow the Windows PC process and Internet connection. Once Java auto-updates are disabled on the computer, locate the jvm.dll files (801 KB, 2880 KB, etc.) in the Oracle folder and correct them to the necessary version and size that supports your Banner Navigation.
A word of caution. Please restart the computer, or you may get an FRM-41214 Error Message when you try to relaunch Banner Navigation.
