Dbvisit Software Ltd. Dbvisit Overview 1 Agenda • • • • • Dbvisit Software Ltd. Overview Dbvisit Standby Dbvisit Replicate Customer Successes Q&A www.dbvisit.com 2 Dbvisit Software Ltd. • Oracle Gold Partner • Product engineers and technical support are Oracle database gurus • Regular presenters at Oracle events, User Groups, etc. • Developer of the Dbvisit Standby product • The global leader in disaster recovery solutions for Oracle SE • 300+ Customers in 60+ Countries • First product shipped in 2006 www.dbvisit.com 3 Representative Client List 4 Dbvisit Standby • • • • • • A fully featured disaster recovery solution Failover Graceful switchover Automatic creation of standby instance RAC, ASM, OMF Compression, secure, monitoring, encryption 5 Dbvisit Standby - Overview Diagram www.dbvisit.com 6 What is a standby database? • Primary database - Contains production data that must be protected against any kind of loss • Standby database - Copy of production database that can be brought online to become the production database 7 Standby database purpose • Users can be transferred to the standby database (with limited downtime) when main database has a major outage End Goal: Business Continuity 8 Dbvisit Standby Dbvisit Standby Architecture - Detail Diagram Primary Server Standby Server Archive log transfer Redo Production Database Archive log Archive log Archive log Archive log Archive log Archive log Archive log Standby Database Redo Redo Dbvisit Standby consists of 2 independent processes: ⁃ On the primary server ⁃ On the standby server Dbvisit Standby process on primary server www.dbvisit.com Dbvisit Standby process on standby server 9 Command Line or GUI www.dbvisit.com 10 Databases Supported • • • • • • • Enterprise Edition to Standard Edition (no EE Options) Standard Edition Standard Edition One Standard Edition with RAC Cloud deployment (e.g., Oracle on Amazon EC2) Workgroup Server XE 11 Dbvisit Standby Supported Systems • Oracle database + + 8i to 11gR2 32 and 64 bit • OS and storage + + + + + + + + Windows: NT4, 2000-2008, XP, Vista, Windows 7 Linux: Intel, AMD, Itanium, and PPC Unix: AIX, HP-UX, Solaris Oracle ASM Oracle Fail Safe Oracle OMF Oracle RAC Microsoft Cluster Server 12 Additional Uses for Dbvisit Standby • Reporting Database: offset load from primary • Shadow environment: bug investigation, etc. • Capturing snapshots: rollback overnight batch • Test environments: capture snapshots for testing • Offload backups: move backups to standbåy • Planned outages: minimize downtime during maintenance 13 Competitive Systems • Manual Scripting • Lacks documentation, support, upgrades • No guarantee all contingencies considered • Not user friendly, no reports, • Double Take • Copies data blocks – not transaction aware • No protection against database corruption • No reporting of time delay • Ok for file systems, could be used with Dbvisit • Oracle Data Guard – Requires Enterprise Edition 14 Case Study: Pythian “We chose Dbvisit because we could trust it to perform every time.” • Oracle Platinum provider of services for database and application software • 140 worldwide customers • Recognized experts in Oracle database operations and management • 2011 Oracle Titan Award winner - Alex Gorbachev Chief Technology Officer www.dbvisit.com 15 Dbvisit Replicate • • • • Comprehensive, high performance Oracle data replication Real time alternative to GoldenGate and Streams Uses wizards to install and configure Share, migrate, and offload data + + + Designed for both Standard Edition and Enterprise Edition Complete documentation and customer support Ongoing upgrades www.dbvisit.com 16 Dbvisit Replicate • Replicates both: + + DML (data changes) DDL* (structure changes) * Not all DDL is supported (ie create tablespace is not supported) • • • • • • • • Low latency, low overhead, low cost 2- and 3-tier architecture 1-way and 2-way replication Very simple to very complex replication topologies supported Uses efficient redo log-based Change Data Capture Uses its own internal redo log mining technology Full error capture and conflict resolution built-in Robust notification capabilities www.dbvisit.com 17 Dbvisit Replicate Comparison FEATURE DBVISIT REPLICATE GOLDEN GATE STREAMS COMMIT TYPE Optimistic commit.
