RE: Slightly OT: Java in the DB

What I am trying to do seems so simple that I still cannot believe I'm not done yet!

I want to build a web page where a 'normal' (non-privileged) user can go, enter his/her login, see a list of the DB's where he/she has an account, enter a new password, click a checkbox (or -boxes), and have the web page call a <Choose- -utility-here> routine to go out and update the user's password on the selected DBs.

I can do everything except get the DB update to work.

There's no daemon. This is intended to be an on-demand utility. There's a central server/instance that has definitions to all the DBs in the TNSNAMES.ORA file. From this DB I harvest the user logins nightly, to build the list to present to the user. I *know* I can connect, although to do the harvest I create a temporary database link, instead of using Java or whatever.

It's the silly step of changing the password. The problem is that the user may wait until after the p/w has expired, so they cannot log in. I found the OCINewPassword routine will do a password change even on a expired login. But ARG! This is the second (or is it third) method I've tried and they have all had one kind of issue or another.

Any more suggestions?

Exactly what are you trying to do? For having a daemon (or demon, for that matter) lurking in the darnkness of the central server and resetting expired passwords, the daemon needs to maintain a permanent connection with sufficient privileges to change any user's password, typically, a dba connection. If your DBA doesn't use profiles, with the idle time limitation, you can have a permanently connected process which would change password as soon as it was signalled to him. The question is: what would the password be changed to? There are strings which are extremely hard tu guess (username, "qwerty", "password", "tiger") and which would make your username secure. At one of my places of work, I've witnessed the following story: a tech support expert leaves a unix worsktation logged in, as root, and goes home at 6 PM, when cleaning ladies entered the office. One of the cleaning ladies had a 14 years old son which wanted to check the old joke with "rm -rf /". He found out that it really does destroy everything on a unix system. Now, you are absent, your password expires at 7 P.M. and there is an eager help desk person who wants to test "drop tablescpace FIN_DATA including contents and datafiles cascade constraints" that he or she has seen written somewhere. I'll leave the rest of the story to you.
