I am new to rac, hence please forgive if this question is really silly = !! Lets assume that we have to move a 64 bit db having a huge sga to 32 bit = linux rac. Using 32 bit raises the problem of > 4gb sga allocation.=20 Assuming that we do not use the "hugemem" or "VLM shmfs/ramfs" memory = options=20 on linux RH AS3, and want to use the maximum amount of physical ram on = one box,=20 is the following RAC work-around practical from a performance = perspective ?=20 To workaround the limitation of ~4gb sga per instance, what if we create = multiple=20 instances on the same physical box .=20 Hence if i have a 2 box RAC cluster, and i create 2 instances on each = box,=20 ( my_total_sga for 1 database =3D 2 box * 2 instances * = max_sga_per_instance ) This effectively can double the amount of total ram i can allocate to my = database. Please advise if this assumption is correct and practical. thanks & regards ratnesh GE-Financial Assurance Lynchburg, VA ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html -----------------------------------------------------------------
