World-leading Disaster Recovery

Solution for the

Oracle SE database

Affordable Alternative to GoldenGate: –

Data Replication for

Oracle-sourced databases

two replication types

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- 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

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

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
