Hi Eugene,
You can run a server and a locator on the same machine or even in the same
process.
Distributed system properties (see javadocs on DistributedSystem [1]):
locators -- use this to specify one or more locators
start-locator -- use this to embed a locator in a server process
Launcher APIs:
LocatorLauncher.Builder.set(String, String) and
ServerLauncher.Builder.set(String, String) can be used to set any
distributed system properties:
new ServerLauncher.Builder().setMemberName("myname").set("locators",
value).build().start();
System Properties:
Simply prepend any distributed system property with "gemfire." and it can
be specified via a system property.
a) Java API: System.setProperty("gemfire.locators", value);
b) Java command-line: -Dgemfire.locators=value
c) gfsh start command: --J-Dgemfire.locators=value
CacheFactory API:
Properties properties = new Properties();
properties.set("locators", value);
Cache cache = new CacheFactory(properties).create();
The banner (first section) of the Geode log file will show how each
distributed system property was specified (ie, the source of the values)
for the Geode process.
(I'm not sure if there are online geode javadocs or not so the following
are gemfire 8.1 javadocs)
