To change to the parameter startup.maxConnections, please note that downtime is required.
1) Check the setting prior to change:
$ nzsystem showregistry| grep -i maxconn startup.maxConnections =
2) Modify this line in the /nz/data/config/system.cfg file:
startup.maxConnections = 1000
* If the file is missing, you can create it as a new file and append the line into it.
3) Restart using ‘nzstop’ and ‘nzstart’
4) Check again to see if the setting has changed:
$ nzsystem showregistry| grep -i maxconn startup.maxConnections = 1000
