      Philosophy of iTERA HA
  is to auto-correct issues, there

   …this is ideal for most SMB

Built-From-The-Start For Remote Journaling




                Benefit: Built Around most flexible and robust data transport mechanism

              Tech Tip*(1): Hardware mirroring typically does not maintain database or application level consistency while mirroring.
              After unplanned downtime this can cause damaged objects, access path rebuilds, referential integrity and other data
              consistency issues which may take hours to correct before the applications are available.

Transport Journal

  ● Data areas
  ● Data queues
  ● Integrated File System (IFS)
  ● MQ / WebSphere
  ● User profiles
  ● Database triggers and constraints
  ● System values
  ● Spool files & output queues
  ● Program objects
  ● Communication objects
  ● IBM job scheduler entries                    Benefits
  ● Directory entries                            ●   Faster and more reliable object replication
  More…                                          ●   Object changes captured and replicated in real time
                                                 ●   Multiple transport journals per system adds flexibility
                                                 ●   More efficient than FTP

                Tech Tip: The traditional method for transporting object changes uses FTP (file transfer protocol)
                however FTP does not have the performance or reliability of remote journaling. A transport journal is a
                remote data journal that is used by iTERA Availability 6 to package and send changed parts (bytes)
                of objects in FIFO sequence. Each iTERA CRG has it’s own transport journal. It’s a faster and more
                reliable method for replicating object changes than FTP.

Direct Apply




                Benefits
                ●   Efficient and robust apply architecture
                ●   No staging area (log spaces) needed on backup system
                ●   Low I/O generated per transaction
                ●   Easy to manage & monitor because there are few moving parts
                ●   Reliable because there are few moving parts
                                                                                               Vision AutoGuardTM
             Tech Tip: In sophisticated multi-journal, multi-processor and multi-application
             environments the multi-job dynamic apply architecture in MIMIX & OMS has
                                                                                                automatic notification

Real-Time Self-Correction




       Benefits
       ● Spend less time managing HA
       ● Files don’t go ‘on hold’
       ● If a transaction fails to update the backup then the record is instantly self-corrected
         without interrupting mirroring
       ● Operators can review the self-correct history at later stage if they wish to
       ● Helps maintain Role Swap Ready (RSR) status


           Tech Tip: Most common reason why files go ‘on-hold’ (not mirrored) with some HA
           solutions is a single record failed to update. iTERA Availability 6 retrieves an image of   Vision AutoGuardTM
           the record from the primary using RRN and over writes the backup in a parallel stream.       automatic notification
           File doesn’t go on hold and we’re in synch.                                                   and self-correction

Apply Accelerator Self-Correction




           Benefits
           ●   Spend less time tuning HA
           ●   Automatically starts/stops whenever latency detected
           ●   User defined latency thresholds
           ●   Uses memory on backup system to bulk apply transactions
           ●   Can accelerate apply up to 400%
           ●   Preserves database consistency
           ●   Preserves application consistency
           Tech Tip: If apply latency reaches a user determined threshold (minutes or
           transactions) then an apply accelerator job automatically starts and caches the apply     Vision AutoGuardTM
           essentially doing a bulk read and apply. When latency falls below a threshold the apply    automatic notification
           accelerator automatically ends.                                                             and self-correction

     Benefits
     ●   Spend less time repairing HA
     ●   Protect backup database from unauthorized updates without locking it
     ●   Any unauthorized data updates on backup are immediately self-corrected
     ●   No need for iTERA Availability 6 to lock the backup database
     ●   Faster mirroring startup and shutdown
     ●   Less potential for lock conflicts

           Tech Tip: The backup data is journaled by iTERA Availability 6 to a local journal.         Vision AutoGuardTM
           Any updates which are not made by the iTERA HA apply job user trigger the ZZ Audit          automatic notification
           job to retrieve an image of the record from the primary by RRN and self-correct              and self-correction

More iTERA Availability 6 Features 1/2

     No production downtime during install iTERA is designed so that the
     implementation and initial synchronization of the backup system can be done without
     introducing any user down time.


     Library Analyzer iTERA analyzes all libraries and objects and provides valuable input
     to help optimize the mirroring setup (SATLITE Tool)


     Auto Library & Object Registration Customer who periodically create rename and
     delete libraries and objects and want them automatically mirrored can do so. Libraries &
     contents can be defined for mirroring with wild cards. Libraries and contents will be
     automatically journaled, synchronized and mirrored.


     Library Auto Sync. Helps eliminate the need for operators to be present during the
     initial data synchronization. Libraries to be replicated are pre-selected, the journals to
     which the libraries will be replicated are assigned, and a syncing priority status is assigned.
     Sophisticated targeting functionality allows for a wide range of unattended syncing
     possibilities

      MQ / WebSphere Support iTERA replicates the associated MQ Library. Creates the
      Queue Manger, if needed. Creates the queue. Replicates the current messages and other
      IFS objects. Creates the remote journal and receive. Applies the messages to the Backup
      node, then deletes messages as needed.

      Menu Fastpaths All menus are logically and consistently laid out following i5/OS
      naming conventions and standards to make them familiar and easy to use. In addition a
      fastpath technique is used to allow operators to navigate faster and communicate easier
      to others. To access the system monitor for example type ‘1.1’ on any screen…it takes
      you to menu 1 and then option 1 in a single step.

      CRC Audit Allows all records in a file to be checked between source and target without
      sending the records to the target. A CRC code is generated for each record (or block of
      records) on source and target and only the CRC code needs to be compared. This
      greatly reduces the time involved.

      Auto Installation When iTERA is installed on the source system it sends an copy of
      itself to all target nodes and auto installs. Journals are automatically created
