Deploying Services

GridServer uses Grid Libraries to distribute classes, libraries, and other resources to Engines. Grid Libraries provide a solution to the problem of distinct Services requiring different versions of the same resource. They provide the following features:

•

Version control, including optional automatic selection of the most current version of a Grid Library.

•

Resource upgrading without interrupting current Sessions.

•

Specification of dependencies on other Grid Libraries.

•

Specification of which C++ runtime to use and non-default JREs via dependencies.

•

All-in-one packaging for JAR files, native libraries for multiple OSes, .NET assemblies, Command Service executables, R scripts, and Engine Hooks.

•

Specification of Environment Variables and Java System properties.

•

Engines that require different compiler support libraries can participate in the same Service Session.

•

Parameterization of package configuration through the use of property substitution files.

The Resource Deployment feature replicates Grid Libraries from a Manager to Engines. In the simplest sense, this enables you to copy a set of bundled resources to each Engine to run a Service.

This section details how to use Grid Libraries for Service deployment to your GridServer installation.
