VMware Continuent Overview

What is VMware Continuent?

•  Provides data replication between Oracle and MySQL relational databases and to data warehouses and analytics engines, to extend Big Data insight for better business decisions.

•  Makes it simple to host MySQL database clusters in the cloud, in tenant’s private datacenter or between these locations, for continuous data availability even during system failure.

•  Globally redundant disaster recovery, commercial-grade high availability, and performance scaling for business-critical database applications.

VMware Continuent Use Cases 1.  Replication

•  Cost effective alternative to Oracle GoldenGate and Oracle Data Guard. •  Replicate data from Oracle to Oracle, Oracle to MySQL, MySQL to Oracle, and MySQL to MySQL.

2.  Real-time Data Loading into Analytics and Big Data •  Quick and efficient replication from one or more Oracle and MySQL databases to data warehouses and big data

analytics engines such as Hadoop (all distributions), HP Vertica, and Amazon Redshift. •  Extend Big Data insight for better business decisions.

3.  MySQL Clustering for HA •  HA clustering for MySQL databases, including automatic failover, zero downtime maintenance and load balancing. •  Automatically replace a failed primary database server within seconds while maintaining continuous operations.

4.  MySQL Clustering with Disaster Recovery •  Quick and efficient replication to a secondary MySQL database cluster, on tenant’s premise, in cloud, or to a

separate site for disaster recovery. •  Recover quickly and automatically from Database Management System and host failures.

Oracle Replication Technical Deep Dive

VMware Continuent for Replication

•  Logical replication from Oracle (and MySQL) • Replication is executed at the transactional level

– Consistent across transactions when reading and writing •  Transactional stored in a neutral format •  Allows us to apply that data back as a transaction to:

– Another Oracle Instance – MySQL – Data warehouses

VMware Confidential 9

Replication solves important problems for RDBMS users

• Real-time local copies in case the DBMS fails • Real-time remote copies in case the site fails •  Loading data into quickly into analytics, big data •  Feeding edge applications from an Oracle central database • Migrating from to:

– New versions – Less expensive editions – Different RDBMS types, e.g., Enterprise to Standard

•  Source Oracle DBMS requirements: – Supplemental logging – Archive logs – Replicator metadata stored in DBMS – Replicator login with access to catalogs and flashback query – Local process to read REDO logs

•  Target Oracle DBMS requirements: – Replicator metadata stored in DBMS

•  Requires a single open port (2112) •  TLS encryption enabled by default •  Authentication between replicators

Migration Use Case

• Migrate data from: – Non-x86 Installation, e.g. Solaris/SPARC, AIX/POWER, HP-UX/PA

RISC – x86 Non-Linux, e.g. Windows – x86 Non-virtualized

• Migrate data to: – Remote datacenter – Remote cloud provider – Remote virtualized environment

Demo VMware Continuent: Oracle Replication in Action

•  Extract is now very capable:

•  Apply to any Oracle version edition, file format, plus RAC on any OS platform

The latest Continuent 5.0 release adds robust Oracle features

Feature What we support DDL Table-related DDL operations (CREATE TABLE, VIEW, INDEX…) Row changes DML operations on most column types Oracle Versions All versions from Oracle 9.2i onward (9i, 10G, 11G, 12C) Oracle Editions All editions (EE, SE, SE1, XE) OS Platforms Extract from Oracle on: Linux, Solaris, Windows, AIX, HP-UX File Formats OS data files and ASM (Automatic Storage Management, proprietary format) Clustering Supports extraction from RAC

30

Things we still don’t support

Feature Remarks

Transparent Data Encryption aka TDE

Rules out operation on sites with high security requirements

Compressed data Some DDL operations CREATE USER, CREATE/DROP/ALTER TRIGGER,

clustered table setup, etc.

Some data types XMLType, geometric types, BINARY FLOAT/DOUBLE, ANYTYPE, ANYDATA not supported

Certain table types Clustered, nested, and remote tables

Quick failover/failback Currently requires partial replicator reinstallation; not good for local HA use cases

31

Other Features in 5.0 •  Security (authentication, TLS/SSL, certificate) now enabled throughout and by

default •  Improvements to HP Vertica loading and compatibility •  Cleaner installation directory structure

32

Wrap-up •  VMware Continuent replication provides robust, flexible capabilities that have

been battle-tested in demanding customer environments •  Replication features compare favorably to Oracle GoldenGate and Data Guard •  VMware Continuent handles HA/DR, platform and version migration, data

warehouse loading, and edge application use cases
