2 System i Enterprise HA & multi-node clustering System i SMB HA System i Database archiving System i Optimization System i SMB DR + CDP System i, ORACLE, DB2, SQL Server, Sybase, Teradata CDC System p AIX SMB DR +CDP MS Windows Availability, Backup, Flex, Move & Cloud Vision Solutions Product Portfolio

3 ● Reduce disk storage utilization ● Improve ERP application performance ● Defer disk/hardware upgrade ● Accelerate nightly backups ● Optimize environment for HA ● Meet Legal Requirements Business Benefits Why Archive? 100% 50% 90% 75% Disk Utilization Start planning for disk upgrade Critical threshold Increasing risks and Increasing monitoring costs Risks & Costs

4 Near-Line and Off-Line Strategies What to do with Archived Data? On-Line – Data that is stored in the production database and is used for on-line transaction processing Off-Line – Data that has been archived to tape and Is not available to users unless it is restored Near-Line – Data that has been archived from the Production database and now resides on a different Place on disk. It is accessible to users (typically on a read-only basis) On-Line Near-Line Off-Line

5 Considerations Choosing Archiving Solution While Active – 24 x 7 users availability and minimize disruption to housekeeping tasks Preserve Database Integrity – avoid creating orphaned data such as Detail Lines without a Header Skills Required – DBA/Business Analyst and/or Programming Reorganizing Physical Files – recover deleted record space Auditing – who ran which task when over which data and when Recovery – if we accidentally archive too much data how do we put it back?

6 Required Steps Planning an Archiving Project Identify Business Areas Determine Retention Policies Perform Database Analysis Engage Business Users/Data Owners Develop Test Plans Metrics Planning Exercise Project Plan

7 Database Archiving Has Never Been so Easy, Affordable or Flexible ● Reduce disk storage utilization ● Improve ERP application performance ● Accelerate nightly backups ● Optimize environment for HA ● Archive without downtime ● Archive without programming ● Accelerate archiving projects ● Reduce costs of archiving projects ● Suitable for all ERPs *(1) on System i ● Maintain security ● Maintain Auditability ● Near-line and Off-line strategies Business Benefits Technical Benefits Advanced Database Archiving Framework v7.2 Advanced database archiving without downtime without programming v7.2 *(1) Suitable for ERPs running DB2/400 *(2) Vision have pre-defined archiving models for Lawson MOVEX ERP *(3) DIRECTOR is a separate Vision product *(4) REPLICATE 1 is a separate Vision product ● DBA defined archiving models (schemas) ● User exit points for user defined logic ● Variables & Parameters ● Compiled archiving requests for improve performance ● Change management capabilities ● Business transaction level integrity preserved ● While-active archive & restore requests ● Start & stop archive processing to avoid peak times ● Import & export archiving models *(2) ● Add DIRECTOR *(3) to help analyze and optimize database ● Add REPLICATE 1 *(4) to replicate data to other platforms

8 Data Manager Pre-Built Models for M3 Pre-built Archive Models – Data manager Projects which utilize pre-built archive models take significantly less time because many of the business rules are already in the model and only customization and testing is required Archiving should be a normal business process, not a feared project Standard Models ● Customer Orders and Invoices ● Deliveries ● Service Orders ● Many more ● Purchase Orders ● Manufacturing Orders ● Works Orders Special Functions ● FAM – Financial Ledgers ● MITTRA – Stock Transactions ● CINACC ● OSASTD ● OSBSTD Company Copy with Data Manager Test Database – as a consequence of archiving logic, make copy of data AFTER cut-off date to create a subset test database, plus Change Company Number functionality. Advantages: ● Save disk space ● Exclude/include specific Divisions
