Questions on Sybase IQ

Hi

Three questions on Sybase IQ :

1. Is there anyway to recover lost DBA password?
2. Does Sybase IQ support OS authentication?
3. As per Sybase , Volume management software is not recommended for Sybase IQ devices. What is the reason?

Can anyone help ?

thanks

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

1. Opinion is divided. Sybase Tech Support have told some people DBA passwords cannot be recovered for IQ or ASA, and told others that it can.

2. Yes, via Kerberos. You need the separately licensed "Sybase IQ Advanced Security Option" for this. This might not be available in versions below a certain version of IQ.

3. I'm not aware of any issues. Have you been told to avoid them? Raw partitions pretty much beat anything else for performance, but some volume management software is almost as good - and better than standard file systems.

Thanks Joe.

We can find the following message in Sybase IQ training material  :

Volume management software is not recommended for Sybase IQ.

Hm, how odd. I can't find anything to explain that in the Sybase manuals or in any of the IQ presentations at the last few years of Techwave conferences. Ask your instructor?
