Disabling automatic NATS configuration

From DataMiner 10.2.0 [CU6]/10.2.8 onwards, you can enable the NATSForceManualConfig option so that NATS is not automatically configured in your DataMiner System. When you do so, you will need to either configure a NATS cluster manually instead, or manually call the NatsCustodianResetNatsMessage when changes are made to the DMS (see Try a NATS reset).

Caution

If you disable automatic NATS configuration, this means you become responsible for maintaining the configuration of the SLCloud.xml, nas.config, and nats-server.config files as well as ensuring the synchronization of the credentials in the system. From DataMiner 10.3.11/10.3.0 [CU8] onwards, when DataMiner makes changes to any of these files, the old version of that file is saved in the C:\Skyline DataMiner\Recycle Bin folder.

To disable automatic NATS configuration:

  1. Connect to the DMA using the SLNetClientTest tool.

  2. Go to Advanced > Options > SLNet Options.

  3. In the drop-down box, select NATSForceManualConfig.

  4. Configure the option as follows for each DMA in the cluster:

    1. Right-click the DMA and select Edit value.

    2. Specify true and click OK.

  5. Click OK to close the SLNet Options window.

Warning

Always be extremely careful when using the SLNetClientTest tool, as it can have far-reaching consequences on the functionality of your DataMiner System.

Note

Changes to the NATSForceManualConfig option are included in a DataMiner backup to make sure that the automatic NATS configuration status remains consistent after a backup is restored. From DataMiner 10.4.11/10.5.0 onwards, any changes made to the nats-server.config file after disabling automatic NATS configuration will also be included in DataMiner backups. Prior to this, you need to manually back up the nats-server.config file, located in the C:\Skyline DataMiner\NATS\nats-streaming-server\ folder. See nats-server.config file not included in DataMiner backups.
