FRM-92150: WEB client version too new

The error i faced after upgradation of 12.0.6 to 12.1.1 during forms startup.

FRM-92150: WEB Client version too new

The fix is as below:
Go to TOOLS_ORACLE_HOME (10.1.2)
cd forms/lib (in case of Linux) forms/lib32 (in case of other OS)
run
make -f ins_forms.mk sharedlib
it will create shared library functionalites again to run the forms.
The error will not be there..
