I have followed the same procedures as mentioned in https://community.oracle.com/thread/3540985
i.e. unset ORACLE_HOME,ORACLE_SID & PATH variables.
But still the problems comes on 36% of the EM cloud 12c R2 installation with the error message
"ERROR: Unable to continue with the installation because some one-off patches could not be applied successfully.
To resolve this issue, review the following log file:/u02/app/oracle/Middleware/oms/cfgtoollogs/opatch ."
My OS is Oracle Ent Linux 6.4 64 bit. Oracle Database is 126.96.36.199.0, EM is 12c R2 (188.8.131.52)
Please Help me this is urgent for me.(See the attached)
