[root@testserver bin]# su - oracle

[oracle@testserver ~]$ id

uid=505(oracle) gid=505(oinstall) groups=505(oinstall),503(dba),504(oper)

3.2 Change owner of Oracle Database (DB Files)

chown oracle:oinstall /oracle

chown oracle:oinstall /oracle/OL1

chown -Rv oracle:oinstall /oracle/OL1/sapdata*

chown -Rv oracle:oinstall /oracle/OL1/origlog*

chown -Rv oracle:oinstall /oracle/OL1/mirrlog*

chown -Rv oracle:oinstall /oracle/OL1/oraarch
