Solaris 10 physical memory vs swap

We are running Solaris 10 Sparc 64 bit. We have total 8G RAM. It seems like all the processes are swapping even though there is free physical memory. Project for oracle user is 6gb.
prstat -t for oracle user is swap=2250 rss=2450. Why am I swapping?? I would expect to use up all physical memory before swapping.
thanks

What Solaris reports as "free memory" isn't unused memory, it is the "free list" which is a pool of memory pages which the system has decided can be reused to meet future memory demands. If the size of this pool falls below a certain limit, based on the memory size, the system will do a scan to add additional pages to the list. The pages aren't necessarily empty, they are just considered available for reuse. As a result, the free list doesn't go to zero even if you're swapping. The system is constantly adding new pages to the free list which then get consumed by an excessive memory demand.

How solaris calculate virtual Memory ?

Hi,
I am using Solaris 10 on both sparc and x86 server.
I am still unable to comprehend how solaris calculate Total Virtual Memory.
We can check the Virtual Memory in system by SMC tool and by #swap -s command.
swap -s
total: 6071888k bytes allocated + 1010404k reserved = 7082292k used, 52134560k availableAbove output shows that total virtual memory is = 7082292k used, 52134560k available = 57829 MB
Sun documents says that solaris calculate Virutal Memory by combining the available RAM with total swap space
System swap is 32773 MB
And availabe RAM righ now is 22506
# vmstat 1 3
kthr memory page disk faults cpu
r b w swap free re mf pi po fr de sr s2 -- -- -- in sy cs us sy id
0 0 0 55999408 25906620 579 106 1410 2 2 0 0 69 0 0 0 3919 13684 6331 3 2 95

Does any body know how solaris exactly calculate the virtual memory which it indicates in SMC and swap -s ?

If you look at the man page it shows for the -s flag:
available The total swap space in
bytes that is currently
available for future reser-
vation and allocation.
That means if swap has been allocated it wont be shown in this total, Solaris has a funny way of dealing with memory, it will only free physical memory when it needs to reuse it. If you want to tell if a system is paging the best way is to use sar with the -g flag e.g
sar -g 10 10
Or iostat etc

Physical memory and paging

I know in SAP's world, memory means physical memory + paging. I want to know which program has contribution for swap.
Suppose there is 4G physical memory on an application server, em/initial_size_MB = 4G, abap/heap_area_nondia = 4G.
1) If there is no dialog processor running and one background job running which claims 2G memory, I want to know will swap occur?
2) If there is one dialog processor running which claims 2G memory and one background job running which claims 2G memory, will swap occur?

By ST03N you can check the workload, by OS06 the swap .
By transaction ST02 you can check the folllowing parameters:
SAP Roll area parameters
- ztta/roll_first          : First amount of roll area used in a dialog WP
- ztta/roll_area             : size of the local SAP Roll area in the work process
rdisp/ROLL_SHM      : size of SAP roll Buffer
rdisp/ROLL_MAXFS     : size of entire shared SAP roll area
SAP Extended Memory main parameters :
em/initial_size_MB : size of SAP extended memory allocated when                         the SAP instance starts up
em/blocksize_KB : size block which split SAP Extended Memory
ztta/roll_extension : maximum size of a user context in the SAP Extended memory
SAP Heap Memory main parameters :
abap/heap_area_dia       : quotas oh SAP heap memory that a dialog                                 process can allocated.
abap/heap_area_nondia : quotas oh SAP heap memory that a nondialog                    process can allocated.
abap/heap_area_total     : size that can be allocated in total by all work                    process.
abap/heaplimit           : Workprocess restart limit of heap memory
if helpful reward point is appreciated

How to get the amount of free physical memory?

How to get the amount of free physical memory?
(without sudo or root)

vmstat will give it to you.
Although the question depends a bit on what you mean by free memory.
The figure vmstat labels free (in any reasonably recent version of solaris) actually represents memory mostly filled with cached file contents. So it represents memory that can be easily released if needed by something more important.
Like most unix versions, solaris will use any free memory to cache files thats have been read/written previously just in case they are needed again

( Can't detect panicbuf from physical memory list Program terminated

Has anyone seen this error when attempting to install Solaris 8 on a Sparc 10. I receive this error when I attempt to ( ok boot cdrom (enter) )
( Can't detect panicbuf from physical memory list) Program terminated
I think I am having a problem with my physical memory.
Any ideas would be appreciated.
Thanks,

I'm banging my head because I can't find a solution to make my arch-install detect an audio CD
I assume that you mean the optical drive. I don't see a /dev/sr0 in /dev
Does it show up with lsblk or parted -l?
Looks like it's a LiteOn drive.
You can play an audio CD.
mplayer cdda://
mpv cdda://track[−endtrack][:speed][/device] −−cdrom−device=PATH
An audio CD doesn't have a mountable file system on it.

Shown Physical Memory value of BWA in TREXADMIN

Hi,
In BWA I have four blades each with 24 GB of physical memory and 12 GB of swap space. Out of 4 blades, 2 blades are backup (This is what I can see from TREXADMIN).
In TREXADMIN -> Summary, within "Memory" section it shows 94.1 GB Phys-Available. Does anybody know where this number came from? I tried all combination of total physical memory with 2 and 4 blades but I am not getting this 94.1 GB number. Anybody?
Thanks

Thanks for replying.
Tansu,
When you say its approximate total physical memory size means it is considered for all 4 bladeds. Correct?
I checked RSDDSTATBIAUSE and DB_FALLBACK coloumn does containg zero entries as you mentioned.
I am trying to get information of BWA usage. As you know SAP recommend to have BWA usage should be within 50% to have healthy system. If I cehcekd TREXADMIN -> Summary, within "Memory its shows some kind of percentage, which I am trying understand whether it is related for all 4 blades or only 2 blades.
Thanks

Database consuming lot of Physical memory

Hi ,
My database is on version 11.1.0.7.0 and on SUN SOLARIS SPARC.
My server admin just informed me that my database is using lot of physical memory , which i understand is RAM.
I am looking on google also but i am not able to find a way in which i can check on it and see how it can be controlled.
Any help/suggestion would be highly appreciated.
Regards

There are 2 basic methods that Oracle uses memory.
Statically. Oracle allocates memory (for the SGA) when it starts. This memory remains fixed in size.
Dynamically. In order to service a client, memory is needed for that client session. Oracle dynamically allocates memory for such sessions (called the PGA).
When Oracle memory consumptions grows, it must be dynamically allocated memory. Static memory is just that - static. It does not grow in size.
The usual reason for PGA memory consumption to grow is incorrectly designed and coded bulk processing. A single Oracle server process can easily consume all available free memory on the server as Oracle dynamically increases the size of the PGA of the process running the flawed PL/SQL code.
However, one should not be looking at o/s command line commands to determine Oracle processes's memory utilisation. The output of such commands are often incorrectly interpreted.. as shared memory can be (and often is) included to provide a process's memory utilisation. There are notes on Metalink (mysupport.oracle.com) on the topic and how to correctly use CLI commands to view Oracle process memory utilisation.
An easier, and more accurate, view of Oracle memory utilisation can be obtained from Oracle's virtual performance views.
So, a sysadmin e-mailing a ps (Unix/Linux process listing) showing a particular Oracle process "+using too much memory+" is not really solid enough evidence that memory is being abused. One needs to look closer at the type of memory used by the process.

How to get total physical memory on the system thru program

Hi,
I have used kstat for identifying physical & virtual memory. I am able to get the data items of vminfo_t, but vminfo_t doesnot give the total physical memory all I get fro vminfo_t is
free memory, swap reserved, swap allocated, swap available and swap free.
Can someone help me in getting total physical memory of the system.
Thanks,
Ram

I do not believe you can get the physical number of pages through kstat. However, you can get it through sysconf(3C). The argument SCPHYS_PAGES will return the number of pages in the system.
See the sysconf(3C) manpage for more information.

": Not enough physical memory for SHM_SHARE_MMU "

Dear ALL,
": Not enough physical memory for SHM_SHARE_MMU "
This is an error message which occurs while trying to mount the database on startup. I've two database running of solaris. DB1 is running with 700M shared pool size. I want to run the DB2 database with 400M. But if i specify 400M shared_pool size on DB2 it is not mounting. It is only mounting when I specify 200M size of shared_pool. Machine has 4cpu and 4gb of RAM.
I've configured the kernel and shemaphore parameter according to the oracle process.
Any thoughts or suggestions appreciated.

The whole SGA must fit into physical memory (SGA=shared_pool_size + (db_block_buffer*db_block_size) + log_buffer + java_pool_size).

Kernel, virtual and physical memory

Hi,
I would like to get a clarification of the uses of the terms kernel, virtual and physical memory. Functions like kmem_alloc provide non-paged 'kernel' memory, but is this a pointer to a physical memory address, or is it similar to a virtual address that gets mapped by the memory management when it is referenced like virtual memory?
Is there a way to determine a mapping between a virtual address and a physical address? (like vtophys in bsd or virt_to_phys/virt_to_bus in linux) ?
Is all memory that is normally used within a driver (e.g. messages through a STREAM or DMA areas) 'kernel' memory, and is this a direct physical memory address (as asked above)?
Many thanks
S.

Hi,
Most kernel code and device drivers will only use virtual addresses. Yes, it is right!
But I want to access a specific physical address.
Because the bus bridge chip with PCI bus-master access a specific physical address directly.
My system configuration is below:
Platform: IA32
Address map:
0x00000000 - 0x000FFFFF: Main Memory, VGA Frame Buffer, Boot ROM
0x00100000 - 0x0FFFFFFF : Main Memory(DIMM) - 255MB*
0x10000000 - 0xFEBFFFFF: PCI bus memory space
0xFEC00000 - 0xFFF7FFFF: Not Used
0xFFFF8000 - 0xFFFFFFFF: Boot ROM
*My system has 128MB DIMM on board.
The bus bridge chip access a physical address at 0x06000000.
I tested whether it would be set up correctly by using Linux as follow:
1) Memory size is specified to 96MB compulsorily.
init: Linux mem=96M
2) Access to Physical address space via virtual address in kernel space.
init_module(){
va = iormap(0x06000000, size);
*va = value;
value = *(va+n);
3) work good.
I tried on Solaris by the same way.
But I cannot find working.
1) Memory size is specified to 96MB compulsorily.
In /etc/system:
set physmem=23723 <- Page size is 4K in my system. lower than 96MB.
2) Access to Physical address space via virtual address in kernel space.
xxx_attach(){
ddi_regs_map_setup();
ddi_putX(value);
value = ddi_getX();
driver.conf
name="xxx" class="sysbus" reg=0,0x06000000, size;
And I tried access by using /dev/mem.
This also went wrong.
dose anyone have good idea?

Allocate physical memory to process

Hi,
I have a user called qbatch which forks lots of processes. I was wondering in Solaris if it were possible to allocate say 10GB of physical memory to the user (perhaps in /etc/project as user.qbatch)..??..
Am well aware of prctl and projadd/projmod regarding Oracle Shared Memory but can I allocate physical memory to a user..??.. tried looking into pools which doesnt seem to be what I require.
Thanks in advance.

Its exactly the same procedure.

Juan

4GB Physical Memory but 3.67GB Used

Hey there, I'm not so great with computers, I essentially know the basics, and thought might as well post a question about it and see where that takes me. I appreciate the help! Thanks in advance!
I have a 13-inch Macbook pro (Mid 2012) with 4GB memory. I was browsing around and discovered a table in the activity monitor stating the following;
- Physical Memory: 4.00GB
- Memory Used: 3.75GB
- Virtual Memory: 4.51GB
- Swap Use: 35.3 MB
From reading other questions and the responses to them I have realized that Maverick takes up a lot of memory but I'm not quite sure why my swap used isn't zero. I don't have much on this Macbook and have bought it recently. Why is the Swap use not zero? Is it a bad thing that it's 35.3MB?
The reason I was looking around was to figure out if my Macbook would be good to run downloaded games and such on; this is a shared laptop and that's what my brothers are interested in doing for the most part. Yes, we have a huge age gap.
Much appreciated,
Simran

Swap is always used. No big deal. What is a big deal is PageOuts.
About OS X Memory Management and Usage
Using Activity Monitor to read System Memory & determine how much RAM is used
OS X Mavericks- About Activity Monitor
Memory Management in Mac OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.

Running out of Physical Memory "Mavericks"

Greetings,
Just moved to 10.9 (upgrade) not a fresh install from 10.8.5.
My issue is with Physical Memery being really scarce under Mavericks.
I have a MacBook Air Mid 2012 core i7 with 8G of rams. I would think that is sufficient especially with the way I use my system. Mainly production and nothing heavy like virtualisation or video rendering etc....
This is what I have done to try to paliate to the issue:
Cleaned all Caches in the system
     ~/Library/Caches
       /Library/Caches
      /System/Library/Caches
      /var/root/Library/Caches
The system (Mavericks) is still quickly running out of physical memory.
I have notice that in Activity Monitor the "File Cache" is getting really big really quickly. I have also notice that as the "File Cache" is growing, Physicall Memory is shrinking (something to that effect).
What is "File Cache" in Mavericks ?
How can I make sure that the said "File Cache" is not growing too big. I am assuming it needs to grow somewhat since it is there to make the system run faster (again something to that effect).
Any help is much appreciated as this is a production machine and I cannot every 5 minutes run "purge" from the terminal. I am even thinking about upgrading my hardware to a 16G unit
Below is a screen shot of my unit's "Activity Monitor" showing the condition of may ram.
One thing that is weird: I never see any "swapping" done after the upgrade to Mavericks.
I checked into /var/vm and found swap files.
Can I assume that my system is doing swap eventhough "Activity Monitor" is not reporting any ?
Is there any other way to check if "swap" is working ?
Kind Regards,

Physical Memory Upgrade [SAP, Oracle parameter changes]

Hello Guru,
Good day!
I'm not sure if I'm in the correct forum, please bare with me if I'm not.
We are actually planning to increase our Production [Physical Memory] server from its current size 15360GB including [oracle, SAP & OS] to 44GB memory. Do you have any idea how can we calculate to the most needed SAP / DB parameter should be increase after we allocate the 44GB in preparation for Go-Live. Below are details of my systems [oracle version, kernel, R/3 System, OS version, SAP parameter and DB parameter.
Reason for memory upgrade: will create two client in one system with a different number of users and different plant e.g. America / Canada

Thanks and regards,

I feel the best way to get the parameters which needs to be adjusted is to go for EarlyWatch Check after increasing the Physical Memory of your SAP system, as we cannot say how and which parameters needs to be checked and changed.. as there is some dependiblity also between the parameters...
All the best !
