Error E018

Message

[DBC-E018] oratab not found or readable

DBCollect failed to find or read oratab. This file is required to get a list of ORACLE_HOME directories.

Solution: Check if either /etc/oratab (linux, AIX) or /var/opt/oracle/oratab (SunOS) exists and is readable to the oracle user.

If this seems to be ok, please submit a bugreport.
