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


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


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 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.


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 applyessentially doing a bulk read and apply. When latency falls below a threshold the applyaccelerator automatically ends.


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


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 (VRST)

Benefits● Less time and cost spent executing role swap tests

● Production system users and jobs not interrupted while role swap test runs● No tape save/restore required● No system exposure or data loss during test● Users can update data on the backup during the test

Tip: 90% of iTERA customers execute virtual role swap tests during the day without introducing down-time!

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


iTERA Alert

Benefits● iTERA Alert finds the right person and notifies them by e-mail

● Monitors message queues● Selects most important messages by user defined severity thresholds● Sends e-mail to user configurable recipients or groups● E-mails are widely supported by mobile devices● Respond to alerts locally or remotely

Identify monitored messages and message severities

Select notification methodse-mail, text message or message queue

Identify alert recipients depending on time of day plus escalation path

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


Italian Language Support All screens and messages now available in Italian (from SP09)

More New Features in iTERA Availability 6 1/2

Role Swap Readiness Monitor Enhanced Formerly called E2KG has been renamed and enhanced. Allows customers to always know that they are role swap ready

User Profile Replication Enhanced User Profile Replication can now be performed via the iTERA HA transport journal, which provides a more efficient replication method. Replication using the original exit point method is still available.

System Value Replication System Value Replication is an advanced feature and is accessible via menu option 5.8. However, this menu option is not visible unless *SYSVAL is enabled in the Replication Components screen (30.23, F20).

iTERA Availability 6 has been GA since April 2009
