Database on AIX with 16GB pagesize

edited Aug 25, 2015 2:49PM in Database Tuning (MOSC) 1 commentAnswered ✓

Can Oracle Database 12.1.0.2 on AIX 7.1 make use of 16GB huge pagesizes ?

(I already know about 16MB large pages and have no problem there, I am asking on how to configure/use for 16GB ?)

Example: default profile on HMC
Desired memory: 80 GB
Huge Page Memory: 16GB x 3 = 48 GB allocated

[Total memory when I start partition is 80 + 48 = 128 GB]

(Tried below but not working)

vmo -p -o lgpg_regions=3 -o lgpg_size=17179869184

vmo: 1485-111 Invalid value 17179869184 for tunable lgpg_size

Maximal value for tunable lgpg_size is 16777216

Warning: lgpg_regions which depends on lgpg_size, will not be set

How to make oracle database allocate SGA from the 48GB huge memory pool ?

Howdy, Stranger!
