Concepts & SMB Philosophy
Users work on the primary system (A)
Tape backupstake place
on the backupsystem without
causing down timeon the primary
Backup system (B) can be in same room or in another city without
impacting performance
User changes in database files are captured and replicated in real time to a backup systemeither synchronously or asynchronously
The backup database is continuously checked forrole swap readiness (database and application consistency)
and auto-corrected if necessary
If the primary system or a business application experiences down time then the backup
system is available to quickly take over the role of the primary system. Users continue work on
the backup without data loss
Philosophy of iTERA HAis to auto-correct issues, there
are no reports to study ……this is ideal for most SMB
environments.
The backup database is accessible for
read-only applications while mirroring

Built-From-The-Start For Remote Journaling
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.
Benefit: Built Around most flexible and robust data transport mechanism
Leaders Have Vision™ visionsolutions.com 5
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
● Directory entries
More…
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.
Benefits● Faster and more reliable object replication● Object changes captured and replicated in real time● Multiple transport journals per system adds flexibility● More efficient 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
Tech Tip: In sophisticated multi-journal, multi-processor and multi-application environments the multi-job dynamic apply architecture in MIMIX & OMS has apply performance advantages
Vision AutoGuardTM automatic notification and self-correction
Leaders Have Vision™ visionsolutions.com 7
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
Vision AutoGuardTM automatic notification and self-correction
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 the record from the primary using RRN and over writes the backup in a parallel stream. File doesn’t go on hold and we’re in synch.
Leaders Have Vision™ visionsolutions.com 8
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
Vision AutoGuardTM automatic notification and self-correction
Tech Tip: If apply latency reaches a user determined threshold (minutes or transactions) then an apply accelerator job automatically starts and caches the applyessentially doing a bulk read and apply. When latency falls below a threshold the applyaccelerator automatically ends.
Leaders Have Vision™ visionsolutions.com 9
ZZ Audit 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
Vision AutoGuardTM automatic notification and self-correction
User accidentallyupdates data
on backup
Local journal on backup identifiesunauthorized database changes
ZZ Audit automatically sends requestto primary for self-correction
Tech Tip: The backup data is journaled by iTERA Availability 6 to a local journal. Any updates which are not made by the iTERA HA apply job user trigger the ZZ Audit job to retrieve an image of the record from the primary by RRN and self-correct (replace) the record on the backup
Self-correcting updatesare placed in the transport &
apply data path and self-correct the backup

Audit Command Console Self-Correction
Benefits● Spend less time scheduling audit tests● Centralized console for managing all iTERA Availability 6 audit tests● Pre-configured with best practice audits and run intervals● iTERA Availability 6 audits don’t produce reports they self-correct

Virtual Role Swap Test (Under The Covers)
During a virtual role swap test users remain on-line
During the test users sign-onto the backup and update dataand run jobs to make sure that
backup applications areRole Swap Ready
During a virtual role swap test, applyprocessing is suspended whichsimulates un-planned down-time
(freezes the backup data)
During a virtual role swap test ZZ Audit automatically sends request to primary for self-correction. Self
correcting updates are placed in the transport data path and transferred to the remote journal
immediately
After a virtual role swap test apply processing is restarted. Thiswill self-correct data changes madeduring the test and then process the
backlog of transactions in the remote journal to bring systems back
in synch quickly

Data Migration Projects
Tip: Over 20% of iTERA customers also use it for data migration projects
Before Migration Users are live on the old system and database on new system is empty
Electronic Synchronization iTERA HA has the ability to schedule and manage the electronic synchronization of large libraries overnight. ITERA HA then keeps the new system synchronized
Cut Over Test iTERA HA then allows users to sign-on to the new system and verify that the applications are Cut Over Ready. If not then we synchronize any missing objects or libraries until users are happy.
Cut Over is done and users continue working on the new system.
Benefits● Take the down time and risk out of data migration
● No need to courier tapes● No need to work weekends● Cut Over test guarantees success

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

More iTERA Availability 6 Features 2/2
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
