OraTab File :

"Oratab" is a file created by Oracle in the /etc or /var/opt/oracle directory when installing database software. 

It is created by root.sh and updated by the Database Configuration Assistant when creating a database.

A colon, ':', is used as the field terminator.  A new line terminates the entry.  Lines beginning with a pound sign, '#', are comments.

Entries are of the form:
                $ORACLE_SID:$ORACLE_HOME::


[oracle@prim etc]$ pwd
/etc
[oracle@prim etc]$ cat oratab

# This file is used by ORACLE utilities.  It is created by root.sh
# and updated by either Database Configuration Assistant while creating

# A colon, ':', is used as the field terminator.  A new line terminates
# the entry.  Lines beginning with a pound sign, '#', are comments.
