Topology Editor for SAP HANA

HANA Topology Editor is a tool for viewing/editing HANA topology file written in Java.

It supports three different types of topology files:

  1. Exported via hdbnsutil -exportTopology <topology file>;
  2. topology.txt in root directory of full system dump (System DB if MDC);
  3. nameserver_topology_<host>.json in trace folder (HANA revision >= SPS03).

This tool is only designed for below scenarios:

  1. View the topology info from the file exported via hdbnsutil -exportTopology <topology file>;
  2. View the topology info from topology.txt in root directory of full system dump;
  3. View nameserver_topology_<host>.json in trace folder;
  4. Edit/Export the topology and import it back via hdbnsutil -importTopology <topology file> when HANA can't be started up because of the topology issues.
