Kiran Kumar answer helped me as well in resolving an upgrade issue with the below step.
SQL>show parameter compatible
4) Change DB compatible by executing the below command.
SQL>ALTER SYSTEM SET COMPATIBLE = '11.2.0' SCOPE = SPFILE;
I was getting " ORA-43851: LOB feature unsupported below compatible 11.0.0 " error in EX000000.DPR file while doing a upgrade ECC5 to ERP6.0 Ehp6 on windows 2008 / Oracle 11.2 environment
Thanks
