Starting ORACLE instance (normal)
************************ Large Pages Information *******************
Per process system memlock (soft) limit = 32 KB
Total Shared Global Region in Large Pages = 0 KB (0%)
Large Pages used by this instance: 0 (0 KB)
Large Pages unused system wide = 0 (0 KB)
Large Pages configured system wide = 0 (0 KB)
Large Page size = 2048 KB
RECOMMENDATION:
Total System Global Area size is 4226 MB. For optimal performance,
prior to the next instance restart:
1. Increase the number of unused large pages by
at least 2113 (page size 2048 KB, total size 4226 MB) system wide to
get 100% of the System Global Area allocated with large pages
2. Large pages are automatically locked into physical memory.
Increase the per process memlock (soft) limit to at least 4234 MB to lock
100% System Global Area's large pages into physical memory
