check if you can run sqlplus and connect as the oracle user.
If so check your permissions on the group for the $ORACLE_HOME/bin
directory.
They should be rwxr-x---. Also make sure that the oracle exe is SUID

ls -al oracle

it should be something liks
oracle s-xr-x---

the s bit is important.

If not run it on with

chmod 4755 oracle

check if the $ORACLE_HOME and ORACLE_SID are defined for this user.
make sure the $ORACLE_HOME/bin dir is in the PATH environment variable .
