Karaf Integration

Narayana was introduced in the karaf 4.1.0-SNAPSHOT with 5.3.2.Final. You need to build from https://github.com/apache/karaf

Configuration

The narayana configuration file could be found in <karaf-4.1.0-SNAPSHOT>/etc/org.jboss.nararayana.cfg

Quickstart

First you need to install the narayana transaction manager feather and others related.
 karaf@root()> repo-add mvn:org.ops4j.pax.jdbc/pax-jdbc-features/0.8.0/xml/features
 karaf@root()> feature:install pax-jdbc-pool-narayana jdbc pax-jdbc-h2 transaction-manager-narayana jndi
 karaf@root()> jdbc:ds-create --driverName H2-pool-xa -dbName test test
 karaf@root()> bundle:install -s mvn:org.jboss.narayana.quickstarts.osgi/osgi-jta-example/5.3.2.Final

Run the commit example

karaf@root()> narayana-quickstart:testCommit

Run the recovery example

karaf@root()> narayana-quickstart:testRecovery -f
It could crash the karaf and generate the record to recovery. You need to restart the karaf and run the testRecovery command again.
bin/karaf
karaf@root()> narayana-quickstart:testRecovery
