Oracle Grid Infrastructure 19c for Linux

in Database - RAC/Scalability (MOSC) 2 commentsAnswered ✓

Dear all,

Please let me clearly understand a specific portion of the reference

"Oracle Grid Infrastructure Grid Infrastructure Installation and Upgrade Guide, 19c for Linux - E96272-14"

pag 84 of 363

"Reviewing HugePages Memory Allocation".

I read:

"If

 your

 cluster member node operating system memory allocations

 to

 HugePages

 are insufficient for

 the size of the SGAs for all of the Oracle Database instances on the cluster,

then

 you may find that

 one or more of your Oracle Database SGAs are mapped to regular pages,

 instead of Huge Pages

".

Suppose I have a Oracle DBMS RAC with 3 cluster nodes RAC1, RAC2 and RAC3.

Howdy, Stranger!
