NUMBER of failed logins before user account is locked. Www.2cto.com when the number of failed attempts exceeds this value, the user will be locked. In addition, we can also use manual commands to lock users: chuser account_locked = TRUE oracle locks the user chuser accout_locked = FALSE oracle locks the user to unlock the smit lockuser and locks the user smit failed_logins to set the number of logon failures. However, this locking and unlocking method is different from the user locked due to logon failure is locked, because such user locks cannot be unlocked through chuser account_locked = false oracle, you must initialize the number of user logon failures in another way. The command is as follows: chsec-f/etc/security/lastlog-s oracle-a unsuccessful_login_count = 0 source http://blog.csdn.net/xiangsir/article/details/8590314
