Concepts & SMB Philosophy Users work on the primary system (A) 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 Backup system (B) can be in same room or in another city without impacting performance The backup database is accessible for read-only applications while mirroring Tape backups take place on the backup system without causing down time on the primary User changes in database files are captured and replicated in real time to a backup system either synchronously or asynchronously Philosophy of i. TERA HA is to auto-correct issues, there The backup database is continuously checked for are no reports to study … role swap readiness (database and application consistency) …this is ideal for most SMB and auto-corrected if necessary environments.

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. Leaders Have Vision™ visionsolutions. com 4
Transport Journal ● Data areas ● Data queues ● Integrated File System (IFS) ● MQ / Web. Sphere ● User profiles ● Database triggers and constraints ● System values ● Spool files & output queues ● Program objects ● Communication objects ● IBM job scheduler entries Benefits ● Directory entries ● ● More… 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 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 i. TERA Availability 6 to package and send changed parts (bytes) of objects in FIFO sequence. Each i. TERA CRG has it’s own transport journal. It’s a faster and more reliable method for replicating object changes than FTP. Leaders Have Vision™ visionsolutions. com 5
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 Leaders Have Vision™ Vision Auto. Guard. TM automatic notification and self-correction visionsolutions. com 6
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. i. TERA 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™ Vision Auto. Guard. TM automatic notification and self-correction visionsolutions. com 7
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 essentially doing a bulk read and apply. When latency falls below a threshold the apply accelerator automatically ends. Leaders Have Vision™ Vision Auto. Guard. TM automatic notification and self-correction visionsolutions. com 8
ZZ Audit Self-Correction Self-correcting updates are placed in the transport & apply data path and self-correct the backup ZZ Audit automatically sends request to primary for self-correction Benefits ● ● ● User accidentally updates data on backup Local journal on backup identifies unauthorized database changes 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 i. TERA 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 i. TERA Availability 6 to a local journal. Any updates which are not made by the i. TERA 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 Leaders Have Vision™ Vision Auto. Guard.

Virtual Role Swap Test (Under The Covers) During a virtual role swap test users remain on-line During a virtual role swap test, apply processing is suspended which simulates 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 Leaders Have Vision™ After a virtual role swap test apply processing is restarted. This will self-correct data changes made during the test and then process the backlog of transactions in the remote journal to bring systems back in synch quickly During the test users sign-on to the backup and update data and run jobs to make sure that backup applications are Role Swap Ready visionsolutions. com 15

More i. TERA Availability 6 Features 1/2 No production downtime during install i. TERA is designed so that the implementation and initial synchronization of the backup system can be done without introducing any user down time. Library Analyzer i. TERA 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 Leaders Have Vision™ visionsolutions. com 19
More i. TERA Availability 6 Features 2/2 MQ / Web. Sphere Support i. TERA 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 i 5/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 i. TERA is installed on the source system it sends an copy of itself to all target nodes and auto installs. Journals are automatically created Leaders Have Vision™ visionsolutions. com 20
