---GIMR默认使用HugePages
During Oracle Grid Infrastructure installation, the Grid Infrastructure Management
Repository (GIMR) is configured to use HugePages. Because the Grid Infrastructure
Management Repository database starts before all other databases installed on the
cluster, if the space allocated to HugePages is insufficient, then the System Global
Area (SGA) of one or more databases may be mapped to regular pages, instead of
Hugepages, which can adversely affect performance. Configure the HugePages
memory allocation to a size large enough to accommodate the sum of the SGA sizes of
all the databases you intend to install on the cluster, as well as the Grid Infrastructure
Management Repository.
