Oracle 11g hot patching

  • Oracle 11g RAC has the ability to apply patches on a node-by-node basis without service interruption.

Oracle 11g RAC load balancing advisor

  • Starting in 10gr2 we see a RAC load balancing advisorutility.  Oracle says that the 11g RAC load balancing advisor is only available with clients which use .NET, ODBC, or the Oracle Call Interface (OCI).

ADDM for RAC 11g

  • 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.

11g RAC cache fusion protocols

  • 11g RAC improves the cache fusion layer for faster and more efficient pinging between nodes
  • 11g RAC ASMCA
  • Oracle 11g offers an ASM configuration assistant allows you to install cluster file systems (ACFS), ASM instances, ASM volumes and disk groups.

Optimized 11g RAC cache fusion protocols

  • Extends the general cache fusion protocols in 10g to deal with specific scenarios where the protocols could be further optimized.

Oracle 11g RAC Grid provisioning

  • 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”.
