"Possible cause for this error may be a previous installation of Oracle Application Server that was not completely installed or deinstalled. Please perform a deinstall on that home."
I believe I have deinstalled it, together with the database. And when I use runInstaller and choose deinstall, it doesn't show up.
Asking google yields 6 or 7 results, and all but one seems to be from the same person asking in different forums.
Running
find . -type f |xargs grep "10.1.2"|grep -v "./logs/"
in the oraInventory folder tells me this:
Binary file ./Contents/OracleHomesList.ser matches Binary file ./Contents/PatchesList2.ser matches Binary file ./Contents/CompsList2.ser matches ... Binary file ./sessionContext.ser matches ./backup/2009-06-21_12-38-20AM/ContentsXML/inventory.xml:<HOME NAME="oracleas1" LOC="/some/folder/10.1.2/as_1" TYPE="O" IDX="2"/>
I'd rather not edit binary oracle files without instructions, or wipe the disk, so if someone has an idea, I am listening.
(In case anyone wonders how I got into this I guess it might be because I uninstalled forms and reports (32 bit) together with the database unsin the database uninstaller (64 bit).)
