For shared installations (Client-Server and Multi Site) it is recommended to setup the Search Server as dedicated server or virtual machine.[155]
CADENAS software has to be installed with administration rights. In order not to put already existing software on the server at risk (isolated servers), CADENAS recommends a dedicated server here.
In addition performance issues are important: In case of extraordinary frequent queries the server is blocked.
The recommended procedure of software installation is to locally copy $CADENAS - the same as with any client.
Only ONE PARTapplicationServer is installed. All client - regardless at which location - access this one PARTapplicationServer.
The environment variable $CADENAS_DATA controls which data directory is used. At which directory it points, you can easy recognize on the Server state dialog box -> Environment tabbed page. On this see ???.
[155] On this server the CADENAS license server can also be installed. See Einrichten eines FLM-Servers.
