RAC Installation and Setup—Considerations and Tips for
OS Families: Linux, Solaris, and Windows
There may be some overlap in the material presented in this section with other chapters. The intent is to summarize
proven and well-known tips, tricks, and best practices in setting up and configuring Oracle RAC clusters in the various
variants of popular OS families of Linux, Solaris, and Windows. The list is long and expansive and therefore, not
everything can be covered in detail; salient bullet points follow.
Linux:
•
Use HUGEPAGES especially for large Oracle RAC DBs (according to Oracle documentation,
any Oracle Database with an SGA >= 8 GB qualifies as a large database). HUGEPAGES is the
general rule of thumb for effective and efficient usage of memory within the Linux OS family
•
Configure/set up ASMM, as it is the only Oracle Database Server Automatic Memory
Management technology that is compatible with HUGEPAGES
•
Install all prerequisite packages before installing GI/RAC
•
Create/configure the minimum required OS users/user groups
•
Set up/configure X Windows along with X11 forwarding so that graphical output can be
redirected for common utilities, for example, DBCA, ASMCA, OUI, NETCA, etc.
•
Set up/configure UDEV for ASM disks
•
Configure/set up/utilize asynchronous I/O
Solaris (SPARC):
•
Employ/deploy Oracle VM for SPARC, an effective virtualization approach which allows you to
easily virtualize/partition the physical servers for RAC
•
Check/install the minimum version of firmware on Sun servers
•
Create/configure the required OS users/user groups
•
Set up/configure the recommended/required UDP/TCP parameters for the kernel
•
Set up/configure X forwarding over SSH for graphical redirection of common Oracle utilities,
for example, DBCA, OUI, etc.
•
Create/configure the minimum required OS users/user groups
•
Guest LDOMs should be utilized as Oracle RAC nodes
