Hi team, does anybody know, if it is possible to set two "synchronized" environments with erdas apollo advantage (catalog functionality and image server functionality) where is only limited availibility. The short timeframe for the synchronization across these environments are supposed. Only one environments is supposed to be "master" where the configuration is changed. (it is not cluster, there cannot be shared DB - oracle)
What is need to do it? the same SW versions, paths to data, DB (oracle) synchronization, shared folder - As I read the documentation, there is any shared folder in the case of cluste, what is it used for? Is it any exact folder in the single instalation? Anythng else?
Thank you for your advice

The share folder in a cluster installation contains some configuration files (providers, metadata, etc.) and the thumbnails, pyramids, provisioning, etc. It is quite the same than the config folder in a normal installation.
In your case, you have to synchronize the DB, the config folder and the thumbnails, pyramids, etc. folders. You have also to make sure that all the datasets have the same path (the paths are stored in the DB).
It might also be a good idea to configure APOLLO like a cluster with one node. In that case, you can be sure that all the configuration parameters are located in the same place.
So, when configuring APOLLO, you choose new cluster for each independant installation and all the configuration will be stored in one share folder. You can access to APOLLO normally without the need of a load balancer.
Keep in mind also you may need also to synchronise the Geospatial Portal installations (in C:\Program Files\Common Files\Hexagon\Services\Instances) if you have some customizations.
By the way, can you explain a little bit more why you want to do that? Maybe there are other options.
