DBacount_Profiles.
Is it possible to create a database account (in 9iR2) with a profile or other feature that implements the following:
1) system lock user account after 5 password attempts within 15 minute period
2) lock the account for 15 minutes only
3) teminate session after 30 minutes of inactivity.
did anything change in 11g for the above.

It does not sound thre is a way to lock account for 5 attemtps within 15 minutes. It seems I may need a separate function for this.
FAILED_LOGIN_ATTEMPTS Specify the number of failed attempts to log in to the user account before the account is locked. If you omit this clause, then the default is 10 days.
PASSWORD_LOCK_TIME Specify the number of days an account will be locked after the specified number of consecutive failed login attempts. If you omit this clause, then the default is 1 day.
IDLE_TIME Specify the permitted periods of continuous inactive time during a session, expressed in minutes. Long-running queries and other operations are not subject to this limit.
1) system lock user account after 5 password attempts within 15 minute period
FAILED_LOGIN_ATTEMPTS = 5
2) lock the account for 15 minutes only
PASSWORD_LOCK_TIME = 15/1440
3) teminate session after 30 minutes of inactivity.
IDLE_TIME = 30

Yes, that 15 minute period appears difficult to implement, however 11g has added a logon delay to increase security. See SEC_PROTOCOL_ERROR_FURTHER

so are #2 and #3 correct? is the only issue with #1.
can i do it using a pl/sql function tied to the profile.

You are correct that #2 and #3 are covered.
#1 is covered for 5 tries but not within the 15 minute time limit you are suggesting.
However, the function is only used for password changes, not to verify the logon.
In order to provide additional logon processing and the check that you are looking for, you will need to have a custom logon process for "your application" that would not be enforced for direct connections to the Oracle Database like SQLPLUS.

but this requirement is for direct client.serve connections for users that use sql*plus or winsql or toda to log into database.
Yes, then you will be forced to utilize just the features mentioned above.
You could investigate the "Oracle Advanced Security" option.

Can I run a database job every 5 minutes that checks if there is any locked accounts in the
database for over 15 minutes and unlock them?
This would remove the need to keep calling helpdesk or dba to unlock accounts and meet the
requirement #1.
do you any security hole in doing this?
