Exadata Manageability

• Enterprise Manager is the best product for managing g g gOracle databases

E t i M id lid t d i f• Enterprise Manager provides a consolidated view of the Oracle Exadata Database Machine

• Exadata hardware faults are captured and reported with Enterprise Manager and ASR

Why Are We Interested in Database Management ?

• RAC is a cornerstone technology in the Oracle gyExadata Database Machine

M t f RAC i ti l d E t i• Management of RAC is essential and Enterprise Manager provides breadth and depth

10

Storage Management in RAC Environments

• Detailed storage statistics show breakdown of storage allocation and usage

• Allows for some trending of storage usage over g gtime

11

Capacity Monitoring on Clusters

•Understand overall cluster status at a glancestatus at a glance•Automated diagnostics on the cluster interconnect

Configure Target availability

• High Availability for plugin targets g y g g– Automate the capability of relocate target

Preconfigure target to have a known default host and failover– Preconfigure target to have a known default host and failover host• On agent or node fail, job submitted to move monitoring of

target to surviving hosttarget to surviving host• When agent comes back up, monitoring moved to ‘default

host’

Storage Cell Plug-in

• Home page shows critical components– Monitors data from MSMonitors data from MS

• Storage cell alerts• Notifications can also be done outside EM

View the Oracle Exadata Database Machine as a Service in Enterprise ManagerService in Enterprise Manager

• Systems and Services allows the Oracle Exadata yDatabase Machine to be viewed in a service model

• Provides a rolled up view• Provides a rolled-up view– Service status– Performance

• Can utilize root cause analysis functionality to diagnose the cause of service failurediagnose the cause of service failure

1) Create Systems

• Systems consist of collections of componentsSystems consist of collections of components• For example, group all your listeners or instances

together

21

2) Create Services based on the Systems

If d i d dd k P f d U• If desired, you can add key Performance and Usage charts to the Service

22

3) Define key service attributes

Define key system components

Define Service Level criteria

23

4) Finally create an Exadata ServiceMonitoring many as OneMonitoring many as One

• Create an Aggregate Service to consolidate all the Exadata sub-services you’ve defined

Automatic Service Request (ASR)

• Automatically opens service requests with Oracle for yspecific hardware faults
