 Oracle RAC Today (10g and 11g)
Oracle Tips by Burleson Consulting

Oracle 11g Grid & Real Application Clusters by Rampant TechPress is written by four of the top Oracle database experts (Steve Karam, Bryan Jones, Mike Ault and Madhu Tumma).  The following is an excerpt from the book.

Oracle 10g RAC

Below is a list of the new features:

  • New concept of Service Registration, which aims at helping high availability from the application point of view

  • Cluster Ready Service (CRS)

  • Oracle Cluster Registry (OCR) for maintaining the configuration information

  • Enhancements regarding tools supporting RAC administration – DBCA, SRVCTL, DBUA and Enterprise Manager

  • Virtual IP Configuration for a better high availability configuration for the application access

  • Limited Rolling upgrade with opatch tool

  • Better Workload Management and alignment with Oracle Database Resonance Utility with dynamic provision of the nodes in the cluster

  • Web-based Enterprise Manager Database Control with which one can manage a RAC database and Enterprise Manager Grid Control for administering multiple RAC databases

  • The Automatic Workload Repository (AWR) to track the performance metrics and provide advice and alerts

Oracle 11g RAC

  • Oracle 11g RAC parallel upgrades

  • Oracle RAC load balancing advisor

  • ADDM for RAC (provides cross-node advisories)

  • Interval Partitioning

  • ADR (ADRCI) command-line tool (example below)

$adrci
adrci> set editor vi
adrci> show alert ( it will open alert in vi editor )
adrci> show alert -tail ( Similar to Unix tail command )
adrci> show alert -tail 200 ( Similar to Unix Command tail -200 )
adrci> show alert -tail -f ( Similar to Unix command tail -f )

  • To list all the "ORA-" errors run following command

adrci> show alert -P "MESSAGE_TEXT LIKE '%ORA-%'"

  • Optimized RAC cache fusion protocols

  • Oracle 11g RAC Grid provisioning - the Oracle grid control provisioning pack allows one to "blow-out" a RAC node, without the time-consuming install, using a preinstalled "footprint". 

  • Hot patching

  • Quick Fault Resolution

Future of Utility and On-Demand Computing

Utility computing and on-demand computing are here to stay.  A May 18, 2008 new datacenter press release from Oracle indicates this. 

 

"Oracle is committed to providing our customers with the highest-level of service, and this new facility in Utah will allow us to support our growing On Demand business, as well as the technology infrastructure to support our research and development and customer service requirements."

Conclusion

The ability of grid computing to perform higher throughput computing, distributing process execution across a parallel infrastructure, brings power—massive computing power—to the people.  This chapter gave an introduction to grid computing and its components as well as showing how Oracle is ahead of the game in offering this feature.

NOTE: Rampant author Laurent Schneider has some additional insight into creating an Oracle Automatic Diagnostic Repository (ADR)
