Oracle 8i SGA and memory
Is there something to lock the SGA in memory ? This can permit the SGA to stay in memory and can't be swap.
Any suggestions ?
Thank You.

Re: Oracle 8i SGA and memory
Memory Information:
physical page size = 4096 bytes, logical page size = 4096 bytes
Physical: 2097152 Kbytes, lockable: 1650404 Kbytes, available: 1895808 Kbytes
You may need to also look at the unlockable_mem kernel parameter. This parameter will affect how much memory can be locked. If this value is set to zero, the size of unlockable memory is chosen at boot time.
Hope this helps.

Re: Oracle 8i SGA and memory
Just my personal option, i totally agree with Harry, i prefer increasing physical memory and pining busy objects. - this is my strategy.
hope this is helpful.

Re: Oracle 8i SGA and memory
in addition to the init*ora parameter "lock_sga = true" I do prefer to use "pre_page_sga = true".
And in any case you NEED to set "/etc/provgroup" with a value like
dba: MLOCK
and NO empty lines in. Instead of "dba" you'll have to name your local Oracle-Admin group, of course.
Then you'll have to execute "/sbin/init.d/set_prgrp start".
