Changing the passwords for Hyperion service accounts (version EPM 11.1.2.1)

Hi,

For a security reasons, we are required to change the password of all service accounts every 3 months. Is there any document to follow in case we are changing those passwords?

we are using these product: EPM 11.1.2.1 - all product are installed on windows server 2008 64 bits

Shared Services

Planning

Business Rules

Essbase

EAS

EIS

Financial Reports

Web Analyzer

each of those product has its own database but they all use the same SQL Server username (SQL server 2008).

also we are using Weblogic as web server.

we are looking for any information that can help us changing the SQL password and the hyperion admin as well.
