JPPF Press Kit


Press release: JPPF 6.0

Web administration console

  • same functionality as the desktop console, except for the topology graph and the charts
  • role-based authentication and authorization
  • tested on major web servers: Tomcat, Jetty, JBoss, Open Liberty, Weblogic, Glassfish

Database Services

  • easily create JDBC datasource definitions and propagate them throughout the grid
  • reuse datasource definitions accross job submissions

Jobs Persistence

  • automatic job recovery in case of grid crashes
  • "submit and forget" jobs, then check their completion state and retrieve their results from a separate client later on
  • retrieve jobs on demand from a persistent store and resubmit them to completion if needed
  • pluggable persistence mechanism
  • built-in implementations: database persistence, file-based persistence, asynchronous (write-behind) wrapper and caching wrapper

NIO-based JMX remote connector

  • a fast, scalable, NIO-based JMX remote connector that uses less system resources
  • can be used as a standalone connector
  • perfectly integrated with JPPF (no additional port required in the JPPF server)

Pluggable monitoring data providers

  • plugins for any source of data for JVM/Process/SYstem health monitoring
  • provided data is automatically and immediately available in the desktop and web administration consoles
  • out-of-the-box health monitoring data is implemnted as a built-in monitoring data provider

Persistence and reuse of load-balancers states

  • the state of the adaptive load-balancers can now be persisted, allowing the reuse of optimal parameters without the long convergence phase
  • state persistence is available to client-side and server-side load-balancing
  • pluggable persistence mechanism
  • built-in implementations: database persistence, file-based persistence and asynchronous (write-behind) wrapper

Server configuration now requires a single port for everything, including management and heartbeating

Complex expressions as arguments of execution policies

  • all arguments of execution policies can include scipts and properties substitutions
  • comparisons are no longer limited to available properties and their value, complex expressions can be used instead

Revamping of the heartbeat mechanism for connection failure detection

  • heartbeat mechanism is now available for client-to-server and server-to-server connections
  • configuration simplification: heartbeat only needs to be enabled on the remote peers

Desktop administration console enhancements

  • pick lists are now used in the desktop console to select the visible columns of all tree views
  • added a "select all nodes" button in the topology views and a "select all jobs" buttons in the jobs view
  • load-balancing settings tab was moved to a popup dialog in the topology views
  • master/slave nodes relationships are now visible in the graph view of the topology

Multi-server topologies improvements

Configuration API improvements

Various enhancements

  • server statistics snapshots now have a last updated timestamp
  • the new MavenCentralLocation class allows downloading artifacts from Maven Central
  • a new built-in node connection strategy allows configuration with a single configuration property
  • port of the J2EE connector to Open Liberty
  • the JPPF client code handling the connections state was simplified, resulting in improved robustness and performance
  • JPPF tasks can now access the node they execute on
  • significant performance improvements, based on numerous profiling sessions and stress tests
  • all APIs deprecated in 5.x were removed
  • wherever applicable, setter and modifier methods were refactored to enable method call chaining, allowing a more fluent code style
  • use ScriptDefinition objects wherever JSR 223 compliant scripts are used
  • improvements to the handling of jobs classpath
