This article describes how to configure real-time synchronization between sites participating in GSLB on NetScaler 11.1.
Note: This feature is available only in NetScaler release 11.1.51.21 or later.

Real-Time Synchronization

If you want to synchronize GSLB configuration across slave sites automatically when the commands are executed on master sites, you can use the AutomaticConfigSync option to automatically synchronize the real-time GSLB configuration.

If you attempt to manually synchronize (with the sync gslb config command) a site while it is being autosynchronized, a "Sync in progress" error message appears. Autosynchronization cannot be triggered for a site that is in the process of being synchronized manually.

Instructions

Enable Real-time Synchronization

To enable real-time synchronization by using the NetScaler GUI:

1. Navigate to Configuration > Traffic Management > GSLB > Change GSLB Settings.

   

2. Select the Automatic Config Sync check-box.
   Note: This option must be enabled only in the  site where the configuration is performed.

   

3. Click OK.

   

All logs related to real-time sync are stored in the /var/netscaler/gslb/periodic_sync.log file. Partitioning has no effect on enabling AutomaticConfigSync from the default partition. However, this parameter can be enabled from all other partitions.
