Use DREADD

The DIH accepts the DREADD indexing action, which allows you to send data (that is accessible to the DIH through the file system) directly to the DIH for indexing. Use the following action syntax:

http://DIHhost:IndexPort/DREADD?parameters

When you send this action to the DIH instead of to an IDOL Server, note that:

  • DIHhost and IndexPort are the host and index port of the DIH, not of any of its child IDOL Servers.
  • In mirror mode, DIH sends the data to every child IDOL server for indexing. In simple non-mirror mode, the DIH decides which IDOL server receives index data, but all IDOL servers receive all actions. Use reference-based indexing or DistributeSendMinimal to further reduce the amount of traffic and IDOL Server load by allowing the DIH to distribute index data and index actions.
  • When you use the PreserveDREADD configuration option, all the child servers must have access to the index file.
