In-Depth Information
•
Set up/configure/utilize Network Time Protocol (NTP) or Cluster Time Synchronization
Service (CTSS) for time synchronization across all nodes of the RAC cluster
•
No I/O, control domains, or service domains should be utilized as Oracle RAC nodes
•
Set up/configure the recommended shell limits and system configuration parameters
•
Run CLUVFY at various stages of the RAC setup/configuration process
Windows:
•
Needless to say, 64-bit version of Windows is an absolute must; this is a basic-level
recommendation, part of RAC101. Windows server 2008 R2 SP2 is a good starting point
•
Create/configure the required OS users/user groups
•
Assign/configure Local security policies to the OS “Oracle” user
•
Create the required OS “environment variables” for setting up RAC
•
Set up/configure cluster nodes as “application servers”
•
Synchronize the clocks on all RAC nodes
•
Set up/configure regional/language settings
•
Set up the order of the NICs such that they are set up/bound so that the “PUBLIC NIC”
precedes the “PRIVATE NIC”
•
Enable/configure auto mounting of ASM disks
•
Set up/configure ASM disks as RAW
•
Disable write caching on all ASM disks
•
Configure/set up/utilize asynchronous I/O
•
Create/set up/configure extended partitions on all ASM disks and then create logical
drives within them
•
Use non-shared (local) Oracle Homes on each node; this allows rolling-fashion
patching/upgrades
•
Disable/stop the “Distributed Transaction Coordinator” Windows service on all RAC nodes
•
Make abundant use of CLUVFY at each stage of the RAC setup/configuration process
•
Configure/set up HyperThreading
•
For large databases, set up/configure Windows Large Pages on OS version >= Windows server
2008 R2 SP2
•
Leverage/utilize Performance Monitor, Process Explorer, and Event Log Windows utilities for
troubleshooting/monitoring purposes
•
Any/all other miscellaneous OS-level environment preparation steps
