Technical system is known as a software element installed on host system.
It can be a standalone system or software elements installed in distributed environment.
LMDB gets all the information from the System Landscape Directory where all the systems register itself.
Most of the technical systems contain data suppliers that provides direct information to SLD for registration.
You should therefore always keep the same SLD port.When Solution Manager is initially set up, it transfers complete Landscape from SLD to LMDB in Solution Manager.This also includes the information from Software catalog.Create a specific user for each connected system on the SLD server.Using a single user for several systems is unreliable and prone to "denial of service" attacks.
