Before installation of PARTapplicationServer make sure that all required licenses are available.
PARTsolutions remote without synchronization of catalog data:
There is only one central data directory ($CADENAS_DATA)
All accesses (catalog browsing and search and LinkDB queries) - regardless from which location - run via PARTapplicationServer.
So if you want to use PARTsolutions remote without synchronization of catalog data, an extra license is required therefor.

Note You can hedge against a license failure by setting up a server cluster.
Details on this can be found under Section 1.4.4.1, “ "Connected servers" dialog area ”.
This license is required, if you want to access the PARTapplicationServer with third party systems.
