Narayana JTS standalone quickstart

Overview

An example of how to start and end JTS transactions. A JTS transaction requires an ORB.

Usage

Running Narayana JTS transaction

mvn clean compile exec:java  -Dexec.cleanupDaemonThreads=false -Dexec.mainClass=org.jboss.narayana.jta.quickstarts.TransactionExample

or

mvn clean compile
./run.[sh|bat]

Using the run script will run using OpenJDK ORB.

Driving JTS transaction remotely with ORB API

There is also a second example that you must run manually using a bash script. The example shows how a client can connect to a remote transaction manager (TM) using a CORBA Name Service for looking up the TM. The example runs using OpenJDK ORB:

You need to set 2 environment variables to run the example:

JAVA_HOME: the location of the JDK (JDK8 is needed for orbd)

NARAYANA_HOME: the location of the narayana distribution (you can download it from the http://narayana.io/downloads/ while choosing the option 'Naryana Binary')

The script will also set:

HOST_ADDRESS: the IP of one of your network interfaces. Do not use the loopback connection (ie localhost or 127.0.0.1) please override the setting in start.sh if it is incorrect.

If you are running on Windows you will need to port the script to Windows batch commands.

Running with OpenJDK ORB:

  1. start a CORBA name server
./start.sh NS
  1. start a Transaction Recovery Manager
./start.sh RM
  1. start a JTS Transaction Manager
./start.sh TM
  1. start a transactional client program
./start.sh CL

Expected output

The orbd command is not bundled with JDK >= 11, see JEP 320 for more information. A quick way to get this quickstart running is to reuse the orbd bundled binary.

Install JDK 8, locate the orbd executable under the bin directory and create a symbolic link pointing to it, like so: sudo ln -s ${JDK_8_LOCATION}/bin/orbd /usr/bin/orbd. Tested with OpenJDK 11. The script will run the example using the OpenJDK ORB.

Testing against OpenJDK ORB

The run should produce a line indicating success:
