    2ba300ff-075d-48df-b325-c41c922f7b41

      Hi all,

       

      we are facing problem after upgrading RAM to 64GB, previously our system was running with 32GB, with oracle enterprise linux 5.9.

      recently we upgraded it to 64GB in the system hardware its showing all 64GB but from OS side its showing only 32GB.

      How can i get all 64GB usable.
