ServiceManager Guide
This part of the guide is intended to cover the installation and configuration of gCube services that are not mentioned in the Administration guide. Mainly we refer to services that are not Enabling and that can be installed dynamically by the Infrastructure/VO Managers. The list includes also for each component known issues and specific configuration steps to follow.
Search
The installation of a Search Node in gCube is characterised by the installation of 2 web-services ( in the minimal configuration ) :
- SearchSystemService
- ExecutionEngineService
This is the minimal installation scenario but it's possible to enable distributed search as well and this will required the installation and configuration of several ExecutionEngineServices
HW requirements
The minimal installation requirements for a Search node are a Single CPU node with 2GB RAMm but it's more than recommended to have at least 3GB RAM on the node dedicated to the GHN.
Configuration
The SearchSystemService and ExecutionEngineService have to be automatically/manually deployed in a VRE scope. In addition if we want to configure the SearchSystemService to exploit the local ExecutionEngineService to run the queries ( minimal installation) we should configure the jndi service as follows:
- excludeLocal = false
- collocationThreshold = 0.3f
- complexPlanNumNodes = 800000
