Hi,
We have a database with SGA 60GB, and planning to configure HugePages. I followed Doc ID 401749.1, but its giving an error
Total Physical Memory = 125 GB
---------------------------------------------------------------------------------------------------------------
Linux ah2ha036 2.6.16.60-0.76.8-smp #1 SMP Tue Jan 11 11:23:59 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
---------------------------------------------------------------------------------------------------------------
This script is provided by Doc ID 401749.1 from My Oracle Support
(http://support.oracle.com) where it is intended to compute values for
the recommended HugePages/HugeTLB configuration for the current shared
memory segments. Before proceeding with the execution please make sure
that:
* Oracle Database instance(s) are up and running
* Oracle Database 11g Automatic Memory Management (AMM) is not setup
(See Doc ID 749851.1)
* The shared memory segments can be listed by command:
# ipcs -m
Press Enter to proceed...
***********
** ERROR **
***********
Sorry! There are not enough total of shared memory segments allocated for
HugePages configuration. HugePages can only be used for shared memory segments
that you can list by command:
# ipcs -m
of a size that can match an Oracle Database SGA. Please make sure that:
* Oracle Database instance is up and running
* Oracle Database 11g Automatic Memory Management (AMM) is not configured
