Goals

  • The purpose of the working group is to chart the path towards standardizing our NGAS installs and adopting the newer version of NGAS.

Definitions

  • NGAS node  - a machine running one or more NGAS daemons
  • NGAS daemon  - an NGAS service running on a node, takes http  commands by listening on a port
  • NGAS cluster  - a group of NGAS nodes  tied together by a single relational database, can be in different data centers

Revised NGAS server naming schema proposal. Max host name could be up to 128 characters. Testing would need to be done to make sure functionalities work with long host names.
