Change RAIMA value-archive path

[nahumcueto]

Is it possible to modify the path in which value archives are stored (Windows), and set it up to a folder in a different disk than project's path is? How could I change that path? Thank you.

No, it is not possible to save the value archives in a different directory.
The value archive directories must always be stored inside of the db directory.

Why do you want to change the path?

As a requirement of one of our projects, we must split data (at least the historical values) and runtime/communications in two groups of servers. It is not possible to use Oracle-RDB.

Main group of servers (communication servers) should run the WinCC OA's project (two redundant peers) and the other group of servers (data) should store database and historics.

We were trying to make Archive Managers store their values in a cached shared folder, located in data servers. But it looks not possible.

(We are using WinCC OA 3.15 patch 7)

As written in my previous answer it is not possible to save historical information in a different location.

When talking about historical data you have to keep in mind that also historical alerts are stored in the database. You can also not change the location for saving historical alerts.
The WinCC OA database consists of several parts (configuration data, living alerts, current values, historical data) and all this data must be stored local on the server where the WinCC OA project is started.

Thank you.

For this project we have the following license (with two USB dongles):

• redundancy = 1
• event = 1
• ios = 100000
• distributed = 1
• http = 2000000000
• iec104 = 1
• s7 = 1
• s7plus = 8
• excelreport = 1
• reporting = 1
• mobile_app = 1
• ultralight = 4
• webserver = 1

Could it be possible to split the project as:

• A redundant couple of servers running all project logics (including HTTP-web-ultralight server).
• Another server (or, if possible, a redundant couple) running only the IEC-driver (and the minimum needed managers) to feed data allocated at the other couple-of-servers' database

If it's not possible, how could we archive historics in "data servers" and read field data in "communication servers"? [client requirements].

If you want to split your project into a UI project and a data project you have to use a distributed system.
The data project must be started on the data servers and the UI project will run on another pair of servers.
In that case you will need licenses for every redundant pair of servers. If you have only 2 licenses you cannot use such a project configuration.

In the panels/scripts running in the UI server you have to address the dp elements for the data project (if needed) by the system name.

If you need additional information or if you want to discuss technical details please talk to your colleague Mr. Martinez.
He has submitted a service request (1-5478502616) in the Siemens Support Portal with the same questions you have,
