how to calculate a proper value for vm.nr_hugepages while production database is live and memory_ta
Hi, I downloaded the script to
check hugepages_settings from note: Shell Script to Calculate Values
Recommended Linux HugePages / HugeTLB Configuration [ID 401749.1].
Since our test/qa enviornment is way less activities than prod, I ran the script over current live production environment and got following outcome:
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
