Product Lineup

World-leading Disaster Recovery Solution for the

Oracle SE database

Affordable Alternative to GoldenGate: – Data Replication for

Oracle-sourced databases

Physical Replication “One on one” copy of the primary database in permanent recoveryUse redo apply to keep up to date100% binary copy, database are exact replicas Referred to as a standby databaseBest suited for DR

Logical ReplicationIndependent 2nd database in sync by replication mechanismUses SQL statements to keep up to dateSubset of data is replicatedCross version, cross platformSeparate physical database structureBest suited for information sharing, migrations, real-time reporting

etc

Two Replication Types

Dbvisit ReplicateLogical 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 Cases1) Offloaded reporting and query environments

2) Data warehousinga) “Audit” featureb) Integration with ETL tools

3) Migration projectsa) Term licenses b) Oracle version upgrades, OS platform, to the Cloud, etc.

4) Cloud a) Migrationb) Backupc) Reportingd) 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 fixesPlatform version or application upgradesNew hardware or a migration to the cloudData centre consolidation – e.g. due to a merger or

acquisitionRetiring 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

Migrate previous release database to new release database with:

1. Minimal outage2. Low risk3. Low stress4. Extended testing with live data5. 100% Data integrity

Migration objectives

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.

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)
