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 analytic systems •  Feeding edge applications from the Oracle mother ship • Migrating from Oracle to:

– New Oracle versions – Less expensive editions – Non-Oracle DBMS

changes and DDL

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

Continuent logical replication applies transactions in serial order to targets

Transaction Log (Row changes + Statements)

0 Create table db1.foo 1 Create table db2.foo 2 insert into db1. foo values(1, … 3 Update db1.foo where id=1… 4 Insert into db2.foo values(5,…) 5 Insert into db1.foo values(3,…) 6 Delete from db2.foo where id=5
