HPA Portal installation HPA agent Calypso Agent properties overriding mechanism

Prerequisites

Agent is installed and configured for a standard installation.

In some case, some properties values from the profile files could be overriden.

Override config path

The modified files are stored in : <agent_home>/override_config/profiles

In this directory, the following files are authorized :

  • same name as the profiles file, example : IntroscopeAgent_navigator.profile, IntroscopeAgent_dataserver.profile
  • IntroscopaAgent_common.profile

Override order

The properties in the files are loaded in this order :

  • override profile specific
  • override common file
  • default profile file

An example with the navigator profile, loading order is :

  • <agent_home>/override_config/profiles/IntroscopeAgent_navigator.profile
  • <agent_home>/override_config/profiles/IntroscopeAgent_common.profile
  • <agent_home>/wily/core/config/IntroscopeAgent_navigator.profile

Override properties and hot reloading

The files are are reloaded automatically when they are modified, but not all properties are hot-reloadable. For example :

  • hpa.dumpDirectory is not hot-reloadable
  • hpa.sqlagent.statement.clamp is hot-reloadable

Check documentation or ask support for specific property behavior.
