Archiving and System Optimization Michelle Ayers Advisory Solution Consultant [email protected] June 2010 Vision Solutions Product Portfolio System i Enterprise HA & multi-node clustering System i SMB HA System i SMB DR + CDP System i Database archiving System i Optimization System i, ORACLE, DB2, SQL Server, Sybase, Teradata CDC MS Windows Availability, Backup, Flex, Move & Cloud System p AIX SMB DR +CDP Why Archive? Business Benefits Disk Utilization 100% ● Reduce disk storage utilization 90% Critical threshold ● Improve ERP application performance 75% Start planning for disk upgrade ● Defer disk/hardware upgrade 50% ● Accelerate nightly backups ● Optimize environment for HA Increasing risks and Increasing monitoring costs ● Meet Legal Requirements Risks & Costs What to do with Archived Data? Near-Line and Off-Line Strategies 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Data that is stored in the production database and is used for on-line transaction processing Off-Line – Data that has been archived to tape and Is not available to users unless it is restored Near-Line – Data that has been archived from the On-Line Production database and now resides on a different Place on disk. It is accessible to users (typically on a read-only basis) Near-Line Off-Line Choosing Archiving Solution Considerations 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? Planning an Archiving Project Required Steps • Identify Business Areas Planning Exercise • Determine Retention Policies • Perform Database Analysis • Engage Business Users/Data Owners • Develop Test Plans • Metrics Project Plan v7.2 Advanced Database Archiving Framework Business Benefits Technical Benefits ● 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 v7.2 Advanced database archiving without downtime without programming 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 *(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 Database Archiving Has Never Been so Easy, Affordable or Flexible 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 Standard Models ● Customer Orders and Invoices ● Purchase Orders ● CINACC ● Deliveries ● Manufacturing Orders ● OSASTD ● Service Orders ● Works Orders ● OSBSTD ● Many more Special Functions ● FAM – Financial Ledgers ● MITTRA – Stock Transactions 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 Archiving should be a normal business process, not a feared project Optimisation Work with System Status WRKSYSTS – System i command, can be run from green-on-black command line (Intermediate Assistance Level) (See also DSPSYSSTS) Work with System Status 06/11/10 % CPU used . . . % DB capability Elapsed time . .
