Oracle's Dumbest Error Message

Expert Oracle Database Tips by Donald BurlesonFebruary 22, 2015


Some DBAs say that Oracle development has gone overseas, and improper English is one symptom of un-American code.  

To illustrate this point, check out this double-negative message in the RMAN-07505:

RMAN-07505: no files found to be unknown to the database

 So, if no files are found to be unknown, does this mean that all files are known?  

If all files are known, why display the RMAN-07505 message at all? 

According to the oerr utility, there is no reason at all for this message:

RMAN-07505:  no files found to be unknown to the database  

Cause:  This is an informational message displayed by the CATALOG command. The command either found no files, or all files that matched the specified search pattern were already present in the target database control file.  

Action:  No action is required.
