Function-execution example

This is a very simple example showing how to execute a function on the server.
It creates a Cache using the CacheFactory, configures a Pool with a PoolFactory, and configures a Region with a RegionFactory. The startserver script deploys a jar file with several custom functions in it, and the example app executes those functions and prints out the result set(s).

Prerequisites

• An installation of Apache Geode.
• Apache Geode Native, built and installed.
• Apache Geode Native examples, built and installed.
• A GEODE_HOME environment variable set to the location of the Apache Geode installation.
• GEODE_HOME/bin in the execution path.

Running

1. Set the current directory to the function-execution directory in your example workspace.

$ cd workspace/examples/cpp/function-execution

1. Run the startserver.sh script to start the Geode server, create a region, and populate the region with sample data.

$ sh ./startserver.sh
/Users/user/geode/bin/gfsh

(1) Executing - start locator --name=locator
...
(2) Executing - deploy --jar=../../utilities/example.jar
...
(3) Executing - start server --name=the-server --server-port=50505
...
(4) Executing - create region --name=parition_region --type=PARTITION

Member     | Status
---------- | ----------------------------------------------
the-server | Region "/partition_region" created on "the-server"

1. Execute `function-execution` from the `build` directory:

$ build/function-execution Result count = 3

   Result[0]=VALUE--1
   Result[1]=VALUE--2
   Result[2]=VALUE--3

1. Stop the server

$ sh ./stopserver.sh /Users/user/geode/bin/gfsh (1) Executing - connect ... (2) Executing - shutdown --include-locators=true

Shutdown is triggered
