Error E016
Message
[DBC-E016] oraInst.loc not found or readable
Explanation
DBCollect failed to find or read oraInst.loc. This file is required to get a list of ORACLE_HOME directories.
Solution:
Check if the file /etc/oraInst.loc exists. If it is not there, Oracle is probably not properly installed.
Solution 2:
Manually provide an ORACLE_HOME using the --orahome option
Further info:
The oraInst.loc contains information on where the Oracle Inventory resides. If this information is not there, dbcollect cannot find the Oracle Inventory.
