  15. System Overview DPSync – How It Works

  16. DPSync – How It Works Analysis and Design • Analyze actual ADABAS data content • Generate, view and modify system-recommended RDBMS schemata • Select an RDBMS schema • Modify the schema • Define conversion processes • Map ADABAS files/fields to RDBMS tables/columns • Result generates the DPSync Metadata and RDBMS DDL statements • Intuitive interactive user interfaces, including GUI

  17. ADABAS File Analysis Statistics of MUs and PEs for sizing of child tables and potential de-normalization of tables to individual column(s).

  18. ADABAS File Analysis Statistics of alphanumeric fields for candidate variable character text columns.

  19. ADABAS File Analysis This screen shows descriptor/superdescriptor usage statistics to determine candidate Primary Keys and indexed columns.

  20. Auto Generation Example: Four tables with Primary Key and Foreign Key constraints, and the added DPS PE Sequencer (PE occurrence). RDBMS Modeling and Mapping

  21. Materialization (ETL) DPSync – How It Works • Standard utilities – no programs to write or maintain • Automatic DDL generation • High speed extraction via ADASAV Utility • High speed RDBMS loaders • Complex data transformations and conversions • No Problems with concurrent ADABAS updates

  22. Real-Time Replication - Overview DPSync – How It Works

  23. DPSync – How It Works Real-Time Replication: Interception of the Changes • Standard ADABAS Replication Exit • Volume Spikes Handled • Gaps Are Managed • No Impact on ADABAS Performance

  24. DPSync – How It Works Real-Time Replication: Transformation & Delivery • Automated Analysis and Design • Sophisticated Transformations, including Child and Grandchild Tables from PEs and MUs • “Paced” SQL TCP/IP Transmissions • Only ET’ed Transactions Shipped

  25. DPSync – How It Works Real-Time Replication: Applying The Updates • No Programs To Write • Sophisticated RDBMS Structures, Including Child & Grandchild Tables from MUs and PEs • Adheres To RDBMS Foreign-Key/Referential Integrity Constraints • “Paced” SQL TCP/IP Transmissions and Queue • Journal and Error Log • Automatic RDBMS Error Notification via Email • Built-In Error Recovery via Scripts • Multi-Threaded

  26. DPSync – How It Works Real-Time Replication: DPSync Console • Statistics • System States • Error Recovery Scripts • Run-Time Parameters • Journal and Error Log Display • Error Retry • Security

  27. DPSync – How It Works Real-Time Replication – DPSync Console : Statistics and System States • Latency Times • Queue Times • RDBMS Times • Number ADABAS Transactions • Number SQL Statements • Number of Errors • System Paused • System Halted • DPS/R-RSU Connection States • Overruns (Volume Spikes) • Etc.

  28. DPSync – How It Works Real-Time Replication – DPSync Console: Maintaining Error Recovery Scripts • Conditions and Groups • Email Definitions • Email Groups • Actions by Error Type: • Pause • Retry • Halt the System • Write to Error Log • Notify via Email • Ignore • Options By Error Type • Email Text to Send • Etc.

  33. Points of Distinction DPSync vs. Other Software Products • Loading the Initial RDBMS (ETL) • Lost (Replication) Data • Detection and Notification of RDBMS Errors • Ease of Implementation • Ease of Maintenance • Transformation Facilities • The Total Solution

  34. Points of Distinction Two Ways to Load the Initial RDBMS • Full Live Extracts • Use High-Speed ADASAV and High-Speed RDBMS Loaders

  35. Points of Distinction Flawed Method For Loading the Initial RDBMS Use “Live Data Extracts” Flaws: ADABAS ADABAS Replicator Memory Queues Msg Software • No Use of High-Speed Loaders • Concurrent ADABAS Updates Can Cause RDBMS Errors • Time Constraints • Requires Special Programming Before/After Images Extracts For RDBMS Load Replicated Changes Complex Transformations Simplex Transformations “Live Extract” Utility Example Transfor- mation JDBC App. Example JDBC App. Customer-Written Application Program RDBMS

  36. Points of Distinction Loading the Initial RDBMS Flaws In “Live Data Extracts” Alternatives for Circumvention • Lock-out ADABAS Updates during the entire RDBMS Load • Custom Programming (Customer-Written Loader Program)

  37. Points of Distinction DPSync: Loading the Initial RDBMS • Standard Utilities – No Programs to Write • Replications Are Accepted and Queued • Until the RDBMS Load completes • Built-In Sophisticated Transformations • High-Speed
