VMware Continuent 5.0 is a complete data replication solution that includes all the functionality you need at one low price. In this webinar, you’ll see how VMware Continuent delivers: - Migration. Replicate from an old version of Oracle, often running on non-Linux platform (Windows, AIX, HP-UX, Solaris), to a new version of Oracle (often running in Linux). VMware Continuent supports heterogeneous environments. - On-boarding to Cloud and Service Providers' data centers. Replicate from an old version of Oracle, often running on non-Linux platform, into a virtual or cloud-hosted environment. VMware Continuent is “Cloud-ready”. - Replication into Analytics (Hadoop, HP Vertica, Amazon Redshift). VMware Continuent offers real-time data loading into analytics and Big Data. This often includes Oracle running on Linux replicating into Hadoop/Vertica analytics. - Replication to MySQL (and PostgreSQL). There is a lot of interest by customers to save money with open source databases. VMware Continuent supports two-way replication between Oracle and MySQL, and allows off-loading workloads to cost-saving MySQL databases. VMware Continuent will soon allow migration from Oracle to PostgreSQL. Don’t miss this opportunity to learn about the alternative to Oracle’s tools!

3. VMware Continuent Overview

4. 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.

7. 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.

8. Oracle Replication Technical Deep Dive

9. 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

10. 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

17. VMware Continuent places minimal demands on source and
target DBMS instances
• 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

22. 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

29. DemoVMware Continuent:
Oracle Replication in Action

30. • 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

31. 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

32. 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

33. 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
