[DOUBT] Memory high in idle process on Solaris 10 (Memory Utilization > 90%)

http://www.unix.com – 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? I have statement about memory on solaris, is this true: Memory in solaris is used for I/O cache, so if there is no memory in used, memory will be used by I/O cache. If the Application need memory, the I/O cache will release the memory. If the "sr" value on vmstat > 300, there is bottleneck on memory. What is the mechanism of memory utilization on solaris? Any comments ar (HowTos)

process memory size solaris 17 weeks 4 hours ago

Running perl script in solaris 10 machine. Know the RAM Size is 25 GB. Have two queries.

Normally How much RAM memory a solaris process is allocated. Is it a default value assigned to any script or process. where it can be set? How do i determine how much max static array size can i have and how much dynamic memory can i allocate?

dear all,

kindly i want to check my server memory utilization i used alot of commands but i want to make sure that it is acurate let me explain

i have a server which has 32GB RAM

Total Memory = 33423360 kb Free Memory = 4172568 kb Utilized Memory = 29250792 kb Memory Utilization Percentage = 87.5 %

if Utilized Memory = 29250792 kb how can i make sure which processes eat this amount of memo

We're facing intermittent periods of 100% CPU utilization.

Server Configuration:HP DL580 G7 (4 Processor with 8 cores each; 128GB memory.) Operating System: Solaris 10_x86 update 9 Application: Oracle 10 R2; ASM for Disk Management.

I have been running Ubuntu 12.04, 64 bit, on my AMD desktop for quite some time. Last few days, I have been seeing the memory utilization of compiz to be increasing. I normally do not shut down the computer, however, recently the memory utilization when no apps are running is about 1 GB.

I want to measure memory utilization of my Apache Server. Can I use pmap command and pass all the process ID of 'httpd' and take that as total utilization ?

pmap PID1 PID2 ....

It seems that pmap give more info rather than RAM utilization. Any command in Unix/Perl through I get the correct info of memory utilization ?

Every process has the possibility to address 2^32 or 2^64 bits of virtual memory. The moment you request to read or to write to one of these memory address', it is converted to a physical memory location (based on the process ID) as it is sent to your L1 data cache.

clear cache memory 33 weeks 4 days ago

hi all,

i have noticed that my server has 64 GB RAM and i have application in this server but the server has free memory only 15% and utilized 85% however it didn't eat from swap .

does any parameter can be configured in kernel to make the system clear memory from cache like linux

i found this command for linux and it worked it free the memory in redhat i want something like this in solaris ?

Hello All,

We have a jave server running on both linux and Solaris environments.

On solaris,it consumes only 600-700MB whereas it goes upto 21G in Linux.

I am monitoring the memory consumption through top command.

Is this high memory consumption expected in Linux?

I have the following questions regarding Linux memory:

I know that the active memory is the portion of memory which is most frequently accessed. But can someone explain me how linux considers a memory location to be utilised for active memory or inactive memory. What all components does active memory comprises of ?
