Hi All,

We have a DB2 v9.1 installed on AIX box.

When DB2 server was started that time some unknown source has tried to create a database connection using wrong password multiple times using some program, resulting into password got locked for that user-id.

We restarted the server, and to unlock the account we updated the user profile in /etc/security/user/lastlock file results into password got unlocked for that user profile.

But now when we are trying to start the DB2 instance we are getting:

$ ./db2start
SQL1042C An unexpected system error occurred.
SQL1032N No start database manager command was issued. SQLSTATE=57019

Would appreciate if can give some inputs from your end.

The information you are looking for is in db2diag.log
