system.properties notes

Occasionally there may be a need to edit the system.properties file used by any station running on a host, which for any NiagaraAX platform is located in its System Home!/lib folder.

On a remote JACE (QNX OS), this folder is at /niagara/lib.
On a local Supervisor (Windows OS), this folder is at C:\niagara\Niagara-3.8.xxx\lib.

Note the system.properties file in a Workbench PC or Supervisor platform is similar to, but different from this same file on a remote JACE platform.

You cannot directly edit in place the system.properties file on the JACE. Instead, you must copy it to your PC first (using the platform File Transfer Client) to edit.

Only a few entries in a sysem.properties file are typically processed. Most lines in this file are comments, which start with a # and are not processed. Comments “inactivate” many entries in this file—and typically these entries should remain inactive. To activate such an entry, you must delete the leading # character on that line of code.

CAUTION: Editing (and activating) system.properties entries is an operation for advanced users, with the possibility of undesirable results. Read all comment lines carefully, and consult your support channel before making a change! Always save a backup copy of this file, and test after implementing a change.
