Announcements

  • NOW AVAILABLE | ICLUSTER VERSION 8.3.1

    We're excited to announce that iCluster 8.3.1 is now available to customers on the Rocket Customer Portal.

    Highlights of this release include:

    Replication enhancements

    • iCluster now supports the replication of SQL objects on IASP, similar to replication for other objects such as native objects and BSF files.

     

    Sync Check enhancements

    • A new option has been added to only refresh the journal information of objects that are out of sync with the JRN (journaling on target) reason code.

     

    Status Monitor

    • It is now possible to directly work with objects (WRKOBJ) from the “Work With Object Status” panel.

     

    Other Changes

    • Dates in the log will be formatted using the system default format.
    • MQSeries version MQ V9R2 is now supported.

    Detailed release notes can be found here.

    Upgrade path:

    You can only upgrade to iCluster release 8.3.1 directly from iCluster 8.3. For releases earlier than 8.3, first upgrade to 8.3 and then to 8.3.1.

  • Now available | iCluster version 8.3

    We're excited to announce that iCluster 8.3 is now available to customers on the Rocket Customer Portal.

    Highlights of this release include:

    Replication enhancements
    • Faster synchronization of source physical files (PF-SRC) by using a record-by-record refreshing method.
    • Support for replication of logical files such as SQL views that are not based on physical files.
    • No numerical limit on Byte Stream File (BSF) specifiers; a longer maximum path name extension to support more types of BSF objects.

    Sync Check enhancements
    New options:
    • A user sync check can now be initiated for a specific file from the backup monitor.
    • Ability to run sync checks sequentially when starting a sync check for a group.
    • New auto-repair options for database files and native objects.
    New detection features:
    • Files with journals that are not being scraped will be reported with reason code JNS.
    • Files that are not journaled will be suspended with reason code EJF.
    • Missing replication information for journaled objects will be reported with reason code RIM.
    Performance:
    • Improved performance when activating out-of-sync objects and byte stream files.

    Status Monitor
    • The collection of performance data for all replication groups has been optimized.
    • E-mail alerts now include the system name in the title.


    Other Changes
    • iCluster has new defaults for sync check type and maximum record level errors for optimal performance.
