High Availability Solution–Try it Now!

Jackie on Tuesday, July 14, 2009

Do you have high availability requirements for your Mule application? Mule High Availability provides basic failover capability for Mule. When the primary Mule instance become unavailable (e.g., because of a fatal JVM or hardware failure or it’s taken offline for maintenance), a backup Mule instance immediately becomes the primary node and resumes processing where the failed instance left off. After a system administrator has recovered the failed Mule instance and brought it back online, it automatically becomes the backup node.

Seamless failover is made possible by a distributed memory store that shares all transient state information among clustered Mule instances, such as:

  • SEDA service event queues
  • In-memory message queues

Mule High Availability is currently available for the following transports:

  • HTTP (including CXF Web Services)
  • JMS
  • WebSphere MQ
  • JDBC
  • File
  • FTP
  • Clustered (replaces the local VM transport)

To learn more about the high availability solution, check out the following resources:

  • A podcast in which MuleSource Sr. Director of Engineering Ken Yagen joins me in a brief conversation introducing the high availability solution
  • A solution overview that provides additional technical information and installation highlights
  • The Mule High Availability documentation page on the MuleSource public wiki (login is required, but registration is free and only takes a moment)

Mule High Availability is available for Mule ESB Enterprise Platinum subscribers. To download a free evaluation copy on a trial basis, contact MuleSource.

    Hi,

    Despite of that is an old thread, i still ask my question:

    Is there a limit of number of queue ? I have a problem with my ESB. I use more than 20 queues and when i switch the order of the queues to test, it never goes to the 20rst and more queue.

    Any solution ?
    Is it because i’m using the community version ?

    Thank you
