Overview - Advanced Platform Configuration section

Overview

This section is only displayed if you have configured more than one of either of the following:

  • Multiple PostgreSQL instances for analysis or measurement requirements - see CSS and Measurement settings.
  • Multiple nodes, i.e. you are running CAST Imaging in distributed/enterprise mode which allows for multiple Nodes to be configured

It allows you to select the specific target PostgreSQL instance (for the database schemas required for the new application) OR the target Node (for deep analysis requirements). If you do not make a selection - i.e. you leave the options set to “ANY”, CAST Imaging will function in “load balancing” mode and will choose the PostgreSQL or Node automatically.

Technical notes

  • If you have ALREADY run a deep analysis, the UI will prevent you from choosing a different PostgreSQL instance or Node for any subsequent analysis related actions to ensure stability.
  • Load Balancing behaviour, when ANY is selected:
    • PostgreSQL > For the deep analysis step (result storage), the PostgreSQL instance with the lowest number of CAST related schemas already stored on it will be used.
    • Nodes > For the deep analysis step, the least busy node running the same release of AIP Core as used for the initial fast scan will be selected.
  • Node manual selection > only nodes running the same release of CAST Imaging Core as used for the initial fast scan of the onboarding process will be made available for selection - this is to prevent analysis errors. This may mean that it is not possible to choose a specific node.
  • See also Managing a node.
