|

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 on Oracle Linux. Before proceeding with the execution please note following:
|
||||
* For ASM instance, it needs to configure ASMM instead of AMM.
|
||||
* The 'pga_aggregate_target' is outside the SGA and
|
||||
you should accommodate this while calculating the overall size.
|
||||
* In case you changes the DB SGA size,
|
||||
as the new SGA will not fit in the previous HugePages configuration,
|
||||
it had better disable the whole HugePages,
|
||||
start the DB with new SGA size and run the script again.
|
||||
And 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
