Hide Oracle password for SQL*Plus

Oracle Database Tips by Donald BurlesonJune 12, 2015

Question:  I have a [problem where the "ps -ef" command shows all SQL*Plus sessions, including the user ID's and passwords!  As the DBA, how can I mask the passwords so that they cannot be seen from UNIX or Linux?

Answer:  There are several methods for hiding or suppressing the SQL*Plus and other command line utilities passwords (SQL*Loader, RMAN, Data Pump).  The most obvious way to mask the Oracle command line password is to not specify it from the command line:

root> sqlplus /nolog
SQL>  connect scott/tiger

But for batch jobs, you must have the passwords in a file somewhere.  One common method is to hide the password into a protected flat file with 700 permissions:

echo mysecretpassword > /tmp/mypass
chomd 700 /tmp/mypass
cat /tmp/mypass | sqlplus -s $USER << eoj >> $LOGFILE 2>&1
