Have you ever used Tivoli, Patrol o TNG for manage Informix?

Hi. List. We are planning to use a 3rd's tool for manage a network of Informix server. Our network is hybrid, we have a few Unix box ( AIX and SCO) with many NT server. So, we have a lot of problem to manage, by example: - Manage the user's account. Specially with the password sinchronization. - Monitor the alarm event. - Manage the backup. - and so on. We are evaluting Tivoli, Patrol and TNG. I really want to know if you use or know about some of them and how do you like it? Why do you select this tools? Are you satisfation with it? I'm going to appreciate your commets and advices. -- Francisco Huezo Administrador de Base de Datos Ministerio de Hacienda Proyecto SAFI Cond. Tres Torres, T-2, N-8 San Salvador, El Salvador Tel.
