What to do before updating a user password?

There are few things to consider before changing a password, Unless of course, it is very clear why a user password update can be done straight away without any further implications.
If you are dealing with a standard user which relates to a person, there is no big deal, update the password with a temporary one and let the user update it with his own password. When dealing with a technical user, you are looking at other issues more important such as batch and backup scheduled procedures which could fail in some cases when a user store key is in use. The user store key will have to be tested and likely to be reinitiated.

Now, changing a user password is easy, but forgetting is also easy, so make sure you keep notes uptodate. Other users may have access to or share the same technical user. Letting any user to modify a user password without a protocol procedure may end up into a complete mess where a user is locked or the password is completely lost. The system password is no exception. Be aware resetting a forgotten or corrupted system password may require shutting down the complete system environment. It is not a Joke. Restarting a production database to change a password would be a very bad move. Make sure you have a user administrator in place to avoid that scenario.
