Changing Passwords for SYS and SYSTEM on Linux/UNIX

Hello DBAs:

 

We are 11.2.0.3 GI and RAC on rhel5.  A co-worker was planning to change passwords for SYS and he found an odd statement in MOS article "How to Change SYS and SYSTEM Passwords [ID 1051982.6]". 

 

"Note that any OS user who is a member of the osdba group (usually 'dba') can run 'sqlplus / as sysdba'.  Because of this it is necessary to change the password of the OS users who are members of this group.  "

 

This was news to me.  I have changed passwords for SYS and SYSTEM many times before and have never modified the OS user's (oracle) password at the same time.  Access as sysdba was not impaired.

Howdy, Stranger!
