Oracle Error Message
ORA-09824: Unable to enable allowmacaccess privilege.
Reason for the Error
ORACLE was not able to turn on allowmacaccess privilege so that it could do a label comparison.
Solution
Check the UNIX error number. If it indicates that ORACLE does not have the allowmacaccess privilege, add the allowmacaccess privilege to the potential privilege set of $ORACLE_HOME/bin/oracle using chpriv (1M). If the executable already has the allowmacaccess privilege, contact Oracle Support Services.
