connections or private network connections for FSE client-server communication. You can retrieve the
parameters that you will use for network configuration using the FSE fse_net tool.
If you are about to configure the interprocess communication in a newly installed FSE implementation, the
configuration must be performed before the first startup of FSE. Similarly, reconfiguring the communications
in an already employed FSE implementation is allowed only while all FSE-related processes (including the
omniNames service) on all FSE hosts are stopped. For instructions on how to perform the configuration, see
”Reconfiguring FSE interprocess communication” on page 75.
FSE implementation with multiple libraries
Attaching multiple libraries provides an option for a scalable FSE implementation. If storage space is
running out, another library can be added to the installation. Media inside the new library can then be
added to existing FSE media pools.
Figure 6 FSE implementation with multiple libraries
If multiple copies on different libraries are needed, the solution is using multiple libraries. Media can then
be assigned to separate FSE media pools dedicated in a one-to-one relationship to each library.
FSE daemons/services and FSE agents
There are several intercommunicating processes running on the FSE implementation. These processes are
either FSE daemons/services or FSE agents.
