Switching Off the Global Listener and SAP MaxDB X Servers
If the database components like database administration tools or database applications (for example an SAP system) and the database system are running on the same computer local communication (shared memory) is used to transfer data between both sides.
For local communication, you therefore do not need X servers and can switch them off.
Exceptions are all components that use the JDBC interface, which requires an X server even for local communication, for example event dispatcher functions in Database Manager CLI. The event dispatcher (calling DBM server) starts and stops the X server if necessary .
If you do not need the X servers you can switch them off.
Switching Off the Global Listener and all X Servers for Communicating with Local Databases
On the command line, stop the global listener and all X servers running on the local computer:
<global_programs_path>\bin\sdbgloballistener stop -all
You can display the global programs path using the dbm_getpath DBM command:
dbmcli dbm_getpath GlobalProgPath
