Product Lineup World-leading Disaster Recovery Solution for the Oracle SE database © 2 0 1 5 D b v i s i t S o f t w a r e L i m i t e d d b v i s i t. c o m | Affordable Alternative to Golden. Gate: – 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 2 nd 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 © 2 0 1 5 D b v i s i t S o f t w a r e L i m i t e d d b v i s i t. c o m |

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 © 2 0 1 5 D b v i s i t S o f t w a r e L i m i t e d d b v i s i t. c o m |

Dbvisit Replicate for 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 © 2 0 1 5 D b v i s i t S o f t w a r e L i m i t e d d b v i s i t. c o m |
Migration objectives Migrate previous release database to new release database with: 1. 2. 3. 4. 5. Minimal outage Low risk Low stress Extended testing with live data 100% Data integrity © 2 0 1 5 D b v i s i t S o f t w a r e L i m i t e d d b v i s i t. c o m |
