Solution to account locking in Oracle

When I used orcle today, I found that the system prompts that the account was locked when logging on to the system account (or another account). I checked the information and found the solution to the problem as follows:

 

CMD

C: \ Documents ents and Settings \ Administrator> sqlplus/nolog

SQL * Plus: Release 10.2.0.3.0-production on Wednesday May 11 09:04:34 2011

SQL> Conn/As sysdba

Connected.

SQL> alter user system (or other accounts) account unlock;

The user has changed.

SQL> exit

From Oracle Database 10g Enterprise Edition Release 10.2.0.1.0-Production

With the partitioning, OLAP and Data Mining options disconnected

C: \ Documents ents and Settings \ Administrator> sqlplus
