PCC-02066:

CMD-LINE: Could not find or could not open system config file
Cause: The system configuration file has a standard name (pmscfg.h) and a location that is operating system dependent. On UNIX systems, it is located in the ORACLE_HOME/proc directory. If a file named pmscfg.h is not found in the standard location, this warning message is issued.
Action: Create a system configuration file in the standard location. The file can be empty. See also the operating system specific Oracle documentation.
