I have few Solaris 11.2 servers. Since sometime, we are noticing high memory utilization in them.
Here is current config
And here is from another server
As I read few forums, I understood that the memory is filled with unmapped pages of data read from disk. It's kept in memory because those files may be read again and keeping the data in memory saves a disk read. That is where, OS is holding up memory. This is leaving less memory, which can be called as 'free'. Though whenever any application or DB needs that memory, OS will release. But our problem is, monitoring system. When total utilization hits 90% (right now it is 89%), it will page out SA.
What can be solution for this issue ?
Any recommendations ?

Hi,
I'm trying to learn how to manage memory when I have to deal with lots of data.
Basically I'm indexing a huge file (5GB, but it can be bigger), by creating tables that
holds offset <-> startOfSomeData information. Currently I'm mapping the whole file at
once (yep!) but of course the... (1 Reply)

Hi Experts,
Our servers running Solaris 10 with SAP Application. The memory utilization always >90%, but the process on SAP is too less even nothing.
Why memory utilization on solaris always looks high?
