Configuration Hints
The UMS Server runs several services in parallel to provide the functionality. These services establish connections to the database. The database must therefore allow a certain number of connections. The recommendation is to set the maximum number of connections and the shared buffer size to the following values:
max_connections = 128 * [number of UMS Servers]
shared_buffers = 128MB * [number of UMS Servers]
These values are set in the configuration file for the PostgreSQL database (see the PostgreSQL documentation).
