Hello All,
I noticed in our new environment while database starts It shows the dump of system resource information for SGA. This is showing us few information of which I am confused.
It says,
--
Per process system memlock (soft) limit =193g
Expected per process system memlock (soft) limit to lock.
Shared Global area into memory 4096M.
Available system page size
4K, 2048k
Supported system pagesize:
pagesize =4K, available_pages=configured, expected_pages=1048581, Allocated pages=1048581 and No errors.
Reasons, for not supporting certain system pagesizes:
2048K- Dynamic allocate and free memory regions
--
Now I am not understanding where from 193G is coming!
cat /proc/meminfo | grep -i Huge
AnonHugePages: 407552 kb
Hugepages_total: 0
Hugepages_free: 0
Hugepages_rsvd; 0
Hugepages_Surp: 0
Hugepagesize: 2048 Kb
cat /etc/sysctl.conf | grep -i huge says nothing.
shmmni=4096
shmall =1835008
shmmax= 6388763852
sem = 250 32000 100 128
Could you please help me to understand where from getting the value 193g?
Oracle versoin: 12.1.0.2.0 and RHEL 6.6
