Lost Oracle SYS and SYSTEM password?
If your administration is as good as anybodies, you are bound to loose the not-so-frequently used password for the SYS and SYSTEM users of oracle. Here are a few ways I found to re-set those passwords:Method 1: SQLPLUS (Tested on AIX Oracle 9.2.0.1.0)
Log into the database server as a user belonging to ‘dba’ [unix ] or ‘ora_dba’ [windows ] group , typically ‘oracle’, or an administrator on your windos machine. You are able to log into Oracle as SYS user, and change the SYSTEM password by doing the following:
$ sqlplus “/ as sysdba” SQL*Plus: Release 9.2.0.1.0 - Production on Mon Apr 5 15:32:09 2004 Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved. Connected to: Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production With the OLAP and Oracle Data Mining options JServer Release 9.2.0.1.0 - Production SQL> show user USER is “SYS” SQL> passw system Changing password for system New password: Retype new password: Password changed SQL> quit
Next, we need to change the password of SYS:
$ sqlplus “/ as system”
SQL*Plus: Release 9.2.0.1.0 - Production on Mon Apr 5 15:36:45 2004
