    Hi Sergio,

    Let me be the first to express how much I like the idea and the Terracotta DSO based solution as well.
    Thank you for making this available to the public.

    I'll refer to this plugin on my company's web site too.

    This is fantastic 

    Any chance this will be supported with 3.10.2 or 3.11 version of JIRA?

    our JIRA installation is quite massive and at the moment we are using 3.10.2. would love to get it working with this version

    thanks for your help

    Hi Segio, 

    Looks like a great plugin. We have been looking for a  jira clustering solution for quite sometime. When do you plan to release a production version? Do you  provide support for this plugin? We are using jira 3.11 and planning to upgrade to 3.12 very soon.

      Hi Akshaya,

      I'm sorry for the late reply.

      The first production release is expected by the end of January, while the first release candidate should be released next week with support for Jira 3.12 and APIs for clustering Jira plugins.

      Commercial support for the Scarlet extension is provided by Sourcesense : http://www.sourcesense.com/en/partners,atlassian.html#scarlet

    Hi Sergio,

    I do not yet study this Clustering solution, but I have already some questions ...

    1. Is there any restriction in the way to develop our plugins ?
    2. In case of Plugins adding some extra OFBIZ Entities, what would be the required procedure ?
    3. What is the processus in case of Upgrade ?

      Hi Vincent,

      here are my answers:

      1. There should be no particular restriction: just use the APIs provided by our extension under the com.atlassian.jira.infrastructure package if you want to cluster the plugin state, create a distributed Jira service or execute a distributed action (that is, a piece of code executed on every cluster node). Are you referring to any particular problem?
      2. The plugin should work as it is.
      3. After upgrading as recommended in the Jira documentation, you just have to install our extension again on every cluster node as described above.

      Feel free to ask for any other information.

      Regards,

      Sergio B.

    Hi Sergio,

    This does sound great.  Currently we are fronting our Jira instance with Apache so we can use SSL.  Would this cause a problem?

    Thanks,

    Hi Sergio,

    We are using an umber of jira plugins (commit acceptance, charting, gantt chart, subversion  etc). Will these plugins work in the clustered environment?

      Hi Akshaya,

      We still don't have a list of plugins that we know will work in a clustered environment out-of-the-box.
      However, any plugin can actually work in cluster, provided that

      • The plugin state doesn't need to be shared among cluster nodes.
      • The plugin doesn't need to take actions on every cluster nodes; if it needs to, you must use Scarlet developer APIs.

      That said, feel free to ask any other question through Scarlet official forums.

      Cheers,

      Sergio B.

    Hi Sergio!

    I have a question I don´t know if you can help me solve it.

    We have installed Jira on AIX 5 and Websphere 6.X  as a "clustered" application with a load balancer. Now we are having problems with the connection to the database beause when a user makes any changes through one of the server the other appication server doesn´t see the changes. I have been reading about your product but i´m not sure if we can use it in our environment.

    Thanks in advance for you help!

    Regards,

    Irene

    Hi Sergio,
    This looks very interesting, I just listened to a terracotta podcast and have an architecture question about Scarlet, hopefully I got the right end of the stick in that Terracotta can be used in a WAN environment. Is it viable to have a WAN-distributed Scarlet jira-nodes deployed, eg node(s) in Austrlia, Canada, US, Europe. Right now latency is killing me, so I'm having to compromise on a centralised Jira node for best all round performance, the ability to distribute node(s) for localised performance benefits would be terrific. Thoughts?

    Cheers,
    Andy.

      Hi Andy,

      thanks for your interest.
      Currently, Scarlet doesn't support WAN deployment and there are no plans about it in the near future.
      However, Sourcesense (http://www.sourcesense.com) provides commercial enterprise support for Scarlet, including custom development based on customer's needs: if you may be interested, feel free to send an e-mail at "info@sourcesense.com", we'd be more than happy to give you all information you may need.
