- Overview
- Oracle 11g RAC has a rolling upgrade features whereby RAC database can be upgraded without any downtime
- Oracle 11g RAC has the ability to apply patches on a node-by-node basis without service interruption.
- Starting in 10gr2 we see a RAC load balancing advisorutility. Oracle says that the 11g RAC load balancing advisor is only available with clients who use .NET, ODBC, or the Oracle Call Interface(OCI).
- In Oracle 11g, ADDM has been extended to include RAC, and provides information on the entire cluster including latency issues on the cluster interconnect, global cache hot blocks (blocks with concurrency issues across multiple nodes), and general object usage information across multiple nodes.
- Oracle 11g offers an ASM configuration assistant allows you to install cluster file systems(ACFS),ASM instances, ASM volumes and disk groups
- 11g RAC ASMCA
- 11g RAC improves the cache fusion layer for faster and more efficient pinging between nodes
- Extends the general cache fusion protocols in 10g to deal with specific scenarios where the protocols could be further optimized.
- The Oracle 11g grid control provisioning pack allows you to "blow-out" a RAC node without the time-consuming install, using a pre-installed "footprint"
