http://stackoverflow.com – 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? what command i need to issue to find it out what memory allocated to a process in solaris? Is it configurable? When the script gives me outofmemory error. Does it mean it used the entire RAM and virtual memory? Is there any way to know how memory was used wh (HowTos)

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.

So, on a Solaris 10 10/09 zone, I am seeing all resident memory being used up.

Hi, I am a newbee in the solaris administration. My question is how to 1. Check the total CPU and memory of a global zone. 2.

On Solaris, the /tmp filesystem is a filesystem of type "tmpfs". It's implemented in the kernel by allocated space from the virtual memory pool.

I have the hs_err_pid of a long running java process that has received a SIGSEGV. In C.6 System Section I can get a rough approximation of the free memory on the system from (MemFree + Buffers + Cached) / MemTotal, but I would like to find out exactly how much memory this process was addressing at the time of the crash, is this captured in this file?

I have an application that reserves a contiguous memory block using VirtualAllocEx on Windows with the MEM_RESERVE flag. This reserves a virtual memory block, but does not back it with a physical page or page file chunk.

We know for every process, it has 4G virtual memory on a 32bit machine. since virtual memory is not physical memory, why don't operating system allocate all it's virtual memory to it, but set a "program break" to limit it's heap space? Even if the operating system allocate all the 4G virtual memory to a process, only when the process access an address that not mapped into physical memo

I have a service in Android which takes a lot of memory and is occasionally removed from running. What is the rule by which Android decides to remove a process? If so - how can I tell I'm about to stop running due to too much memory consumption? Most of the memory I allocate is allocated in native code.

The man page for top defines SHR as:

t: SHR -- Shared Mem size (kb) The amount of shared memory used by a task. It simply reflects memory that could be potentially shared with other processes.

I can see this growing for one process but I am unsure of what exactly is being reported here.
