The glide.discovery.shazzam_ranges_json system property in the London release converts Shazzam payloads into JSON strings, which dramatically reduces their size. When enabled, this property prevents nodes from running out of memory when a single schedule discovers large numbers of IP ranges. In upgraded instances, starting prior to the versions below, this property is set to false and is not visible in the sys_properties table:

• London
• Kingston Patch 6
• Jakarta Patch 9

To enable JSON coding for Shazzam payloads in an upgraded instance, import the update set attached to this article. The update set configures the following:

• Adds the glide.discovery.shazzam_ranges_json property to the sys_properties table.
• Sets the property value to true.
• Exposes the property in the Discovery Definition > Properties module.
