2 Agenda Solutions Network Profile Oracle E-Business Suite R12 POC Amazon Public Cloud Custom Application POC Hybrid Cloud Data Guard Configuration What We Learned Environment and configuration details Q&A

3 Solutions Network (SNET The SNET is a Technology Center of Expertise that combines highly skilled technical resources with a Tier 3 data center that helps Deloitte practice sell and deliver projects, manage investments, and enable our practitioners with the right skills at the right place at the right time. Why this POC? Establish production like capabilities Production configuration High availability Production like SLA s Disaster recovery and data protection Capture effort, skill set and cost estimates Host long term environments on Amazon EC2 Develop leading practices DR process and procedure on Amazon cloud Document configurations for repeatable deployments

5 Oracle E-Business Suite R12 POC Amazon Public Cloud

6 Custom Application POC Hybrid Cloud Technology Components Amazon Virtual Private Cloud Oracle 11g RDBMS Oracle Data Guard Oracle Secure Backup Cloud Module TSM Backup Monitoring tools Expertise Oracle Database 11g and Data Guard Oracle Enterprise Linux Administration Network and Firewall Amazon Web Services EC2 VPC

7 Custom Application Hybrid Cloud

8 Data Guard Configuration Prepare primary database Enable logging Add standby redo logs Add data guard parameters to init.ora/spfile Update tnsnames.ora and listener.ora Prepare standby database environment Install or clone the Oracle home Copy password file (orapwdsid from primary database Add data guard parameters to init.ora/spfile Update tnsnames.ora and listener.ora Create standby database using RMAN Duplicate target database for standby Configure data guard broker Setup database parameters on primary and standby database init.ora/spfile Create data guard configuration for primary and standby using dgmgrl Setup StaticConnectIdentifier for primary and standby Enable data guard configuration Show configuration should return success

9 What We Learned Assessment : Understand the business goals, risk, characteristics of your application and SLA requirements Security : Requirements will vary when deployed in the public or hybrid cloud compared to all in-house Network : Review your application network latency and bandwidth requirements Monitoring : We can monitor instances in the Amazon Virtual Private Cloud using our existing tools, however we were unable to use the tools on Amazon EC2 Cloud Backups : An instance in the VPC can be backed up either to S3 (with OSB Cloud Module or to existing enterprise backup solution. Standby Database : Creation and switchover faster on EC2 to EC2 as compared to in-house to VPC Configuration : Configuring Data Guard on Amazon EC2 or Virtual Private Cloud is not any different from traditional in-house configuration Firewall : Applications or services running on non standard ports on Amazon EC2 will require additional ports to be opened on the corporate firewall.
