Hi,
In Exadata Database Machine 11.2.0.4 Grid Infrastructure and Database Upgrade for 11.2.0.2 BP11 and earlier (Doc ID 1555036.1) <https://support.oracle.com/epmos/faces/DocContentDisplay?id=1555036.1#aref_section226>

You can read: Allocate additional hugepages so that both ASM and database instance can use hugepages
