Welcome to Dbvisit Replicate Overview and Architecture
Agenda • Introduction to Dbvisit Software • Dbvisit Replicate Intro • Dbvisit Replicate Architecture • Dbvisit Replicate Demo • Q&A
Dbvisit Used in 80+ Countries Trusted by 800+ Companies Worldwide leader in disaster recovery solutions for Oracle Standard Edition Exceptional Product Engineers with “real world” DBA Experience Two Oracle 11g Certified Masters Regular presenters at Oracle events such as OOWand Collaborate Passionate about Oracle Technology
Trusted in 80+ countries. . . . . . By 800+ companies.
Product Lineup World-leading Disaster Recovery Solution for the Oracle SE database Affordable Alternative to GoldenGate: – Data Replication for Oracle-sourced databases
Two Replication Types Physical Replication “One on one” copy of the primary database in permanent recovery Use redo apply to keep up to date 100% binary copy, database are exact replicas Referred to as a standby database Best suited for DR Logical Replication Independent 2nd database in sync by replication mechanism Uses SQL statements to keep up to date Subset of data is replicated Cross version, cross platform Separate physical database structure Best suited for information sharing, migrations, real-time reporting etc
Dbvisit Replicate Logical data replication solution • From Oracle to Oracle, SQL Server, MySQL • Topologies: one to one, one to many, many to one, cascading, unidirectional, bi-directional • Wizard-driven interface • Robust notification capabilities • Automated conflict detection and correction • “Audit” feature
Dbvisit Replicate Use Cases • Offloaded reporting and query environments • Data warehousing • “Audit” feature • Integration with ETL tools • Migration projects • Term licenses • Oracle version upgrades, OS platform, to the Cloud, etc. • Cloud • Migration • Backup • Reporting • DRaaS
Dbvisit Replicate- Architecture Components • Mine • Converts Oracle redo log data into PLOG data • PLOG • “Parsed log file” – binary files specific to Dbvisit Replicate • Platform independent • Apply • Converts PLOG data into target DB native SQL ----------------- • Fetcher (optional) • Offloads Mine process from source server onto intermediary server

Dbvisit Replicate for Migrations Migrations happen! They are a fact of life and are required for any number of reasons including: Bug fixes Platform version or application upgrades New hardware or a migration to the cloud Data centre consolidation – e.g. due to a merger or acquisition Retiring old technology
Migration objectives Migrate previous release database to new release database with: Minimal outage Low risk Low stress Extended testing with live data 100% Data integrity

Dbvisit Replicate Feature Highlight:CDC/Audit real-time BI (ii) This does not maintain a copy of the source table(s), but logs all operations as separate entries.
Dbvisit Replicate Feature Highlight:CDC/Audit real-time BI (ii) • New row inserted in staging • table for every: • Insert • Update • Delete
Automated conflict resolution Dbvisit Replicate offers: • Conflict detection Data divergence triggers a notification • Conflict resolution Identifies source of conflict • Conflict handling Predefined rules handle conflicts automatically (includes setting PL/SQL business rules)
Formal Product Training • Workshop style – combining lecture and hand’s on • Available now: Replicate LTD, XTD, MAX • Coming soon: Standby • Conducted via GoToTraining • Short segments (to fit into work schedule)

Summary: Dbvisit Replicate Advantages • Low-cost, quickly deployed data replication solution for keeping a set of databases in sync, real time • Complete, real time system status overview on one screen • Real time notification and extensive reporting included • Automated conflict detection, handing and resolution capabilities • Configurations easily reran or copied over to new environments • Optional: Offload data mining with “Fetcher” tier
Next steps • Plan and carry out POC test? • Size of redo logs and frequency (high and low volume ranges)? • Script to test for supported / unsupported datatypes
