OK, my bad, it’s explicitly written in 9-5-SP1_Command_Central_Help.pdf that :
In a host machine, you might have multiple Software AG product installations. For each
Software AG product installation, you need a separate Platform Manager to manage the
installed products. For example, if you have these installation directories in a host
The Platform Manager that belongs to the C:\SoftwareAG_production installation
manages the products installed under the C:\SoftwareAG_production installation, and
the Platform Manager that belongs to the C:\SoftwareAG_test installation manages the
products installed under the C:\SoftwareAG_test.
Important! To manage Software AG products using Platform Manager, you must install
Platform Manager and the Platform Manager plug-in for the product you want to
manage in the same installation directory.
So I have my answer : it’s not possible to do what I was hoping to do.
This makes it a bit costly to use CommandCentral since it will require the installation of one Platform Manager runtime per component, and with the resource requirements of one Platform Manager instance (256 Mo of RAM and 1 CPU according to SAG documentation), we will have to crank up our machines’ specs to support that.
I don’t think we will follow these stritcly, at least for the CPU, because I don’t think it really means that Platform Manager requires one whole CPU all to itself to run. I would be very interested by sizing information, if anyone that has already used this product can share some?
I think each product that you want to administer through CommandCentral needs its own Platform Manager Plug-in, but I’ve only tested with IS, Broker and MWS, so I don’t know for sure about the others.
Concerning the Platform Manager runtime, you need one for each installation directory, so I’d say you will need one instance for each one of the installations in your list. And for the 2 installations that will be replicated several times, you will have to install a Platform Manager runtime on each replica.
If anybody with more experience in this matter can confirm or invalidate what I say, that would be great.
More generally, any feedback from people with practical experience on these products would be highly appreciated.
Thank you all.
