Large Memory Size (:O )

i created an application that uses 35 MB of memory using the fianal release J2SE 1.4.0
i'm using swing & JAXP "DOM" to parse and save
a 25KB xml file.
my question is:
how can i analyze the memory of my program, in terms of JVM & Application & Objects of Application(swing, JAXP, EJB......), to focus on one part
of it, to reduce the memory size, or at least
know if it is the dcesion of JVM to allocate that memory size.
any suggesstions, articles, URLs will really help
thanks.

i have the same condition also but i found those results:
a. JVM takes about 10 MB of memory.
b. GUI swing about 5-8 MB
c. JAXP takes about 15-20 MB of memory for a 30 KB XML file
which nearly causes a total consumed memory of 25-30 MB of memory. weard results, right.

you can use a profiler, which shows the allocated/created objects...

Very large memory size in process window

I am new to the Mac OS X and in Windows, win explorer never takes any more than 100mb of memory in my processes window, why is it that when i am only surfing one site or no sites but safari is running on the dock, that my memory size is >256mb?! That is just a little to much memory for one program to be taking up considering I only have 512mb.

Hello Applesr4eva:
Welcome to Apple discussions.
This is a very good knowledge base article that discusses OS X memory utilization:
http://docs.info.apple.com/article.html?artnum=107918
Don't compare Windows with OS X. OS X uses sophisticated algorithms to manage both real and virtual memory resources. My advice to you would be to forget it unless you are having performance problems. I am running a G4 with 512 MB and it does not breathe hard unless I use processor intensive applications (rare for me in my home computing environment).

"Fatal error: Allowed memory size of 33554432 bytes exhausted" I get this error message when I try to load very large threads at a debate site. What to do?

"Fatal error: Allowed memory size of 33554432 bytes exhausted"
I get this error message whenever I try to access very large threads at my favorite debate site using Firefox vs. 4 or 5 on my desktop or laptop computers. I do not get the error using IE8.
The only fixes I have been able to find are for servers that have Wordpress and php.ini files.

It works, thanks

Query is allocating too large memory Error ( 4GB) in Essbase 11.1.2

Hi All,
Currently we are preparing dashboards in OBIEE from the Hyperion Essbase ASO (11.1.2) Cubes.When are trying to retrieve data with more attributes we are facing the below error
"Odbc driver returned an error (SQLExecDirectW).

Hi,
Do you have any dynamic hierarchies? What is the size of the data set?

Large page sizes on Solaris 9

I am trying (and failing) to utilize large page sizes on a Solaris 9 machine.
# uname -a
SunOS machinename.lucent.com 5.9 Generic_112233-11 sun4u sparc SUNW,Sun-Blade-1000
I am using as my reference "Supporting Multiple Page Sizes in the Solaris� Operating System" http://www.sun.com/blueprints/0304/817-6242.pdf
and
"Taming Your Emu to Improve Application Performance (February 2004)"
http://www.sun.com/blueprints/0204/817-5489.pdf
The machine claims it supports 4M page sizes:
# pagesize -a
8192
65536
524288
4194304
I've written a very simple program:
main()
int sz = 10*1024*1024;
int x = (int)malloc(sz);
print_info((void**)&x, 1);
while (1) {
int i = 0;
while (i < (sz/sizeof(int))) {
x[i++]++;
I run it specifying a 4M heap size:
# ppgsz -o heap=4M ./malloc_and_sleep
address 0x21260 is backed by physical page 0x300f5260 of size 8192
pmap also shows it has an 8K page:
pmap -sx `pgrep malloc` | more

(The last 2 lines above show about 10M of heap, with a pgsz of 8K.)
I'm running this as root.
In addition to the ppgsz approach, I have also tried using memcntl and mmap'ing ANON memory (and others). Memcntl gives an error for 2MB page sizes, but reports success with a 4MB page size - but still, pmap reports the memcntl'd memory as using an 8K page size.

Jdbc sender channel memory size issue

Hi Experts,
We are facing the below error in connect to jdbc sender channel from XI . Could anyone of you suggest me the right action to be taken in this regard.
Database-level error reported by JDBC driver while executing statement 'select * from*********where posted = '0''. The JDBC driver returned the following error message: 'com.microsoft.sqlserver.jdbc.SQLServerException: The system is out of memory. Use server side cursors for large result sets:Java heap space. Result set size:614,143,127. JVM total memory size:1,031,798,784.'. For details, contact your database server vendor.
Appreciate your quick help.
Thanks & Regards,
Ranganath.

Regulate the number of records returned by Select statement for permanent fix.
Few more things....
a)If you want to select only some fields, then dont use Select * from table. Rather specify select a,b,c from tablename
b) specify some flag in the table so that read some records each time and in the update statement update the flag for those records already read. So that you will not reread the same records in the next message.
Hope you understand.
c) Increasing java heap size is temporary fix.

Problems printing to large paper size

Hi,
Using Acrobat 9
In my work, I use different programs for floorplans and renderings. I send to my Customers the documents as PDF file , and usually the scaled floorplans are in large paper size (22x34 or up)
With one of the CAD programs, all works fine with paper size up to size C, but if I choose, for example, Ansi D, I see a screen "Creating Adobe PDF" but nothing happens, the bar doesn't move and the file is not printed / saved
I'd appreciate any idea to solve this issue
TIA

There are a couple of things you can try; 1.) see if you have enough system memory to process the page ( it could be running out of system memory ); 2.) set an invisible holding line to the page / document and lock it ( no stroke, no fill @ 13 x 19 ); 3.) Use the Page tool ( if you haven't already ) and set it to the document, edge-to-edge. Also, check you ink supplies, there may be an empty cartridge preventing you from printing the entire file. Hope this helps.

Oracle 10gR2 LARGE PAGE SIZE on Windows 2008 x64 SP2

Hello Oracle Experts,
What are the advantages of Large Page Size and how would I know when my DB will benefit from Large Page Sizes?
My undeqrstanding is on Windows x64 – 8kb default page size – will now be 2 MB. Will this speed up accesses to buffer cache? If so is there a latch wait that I can monitor before vs. after to verify that large page size has improved performance?
My Database server has 256GB RAM and SGA is set to 180GB. I am quite sure the overhead involved in maintaining a large number of 8kb allocations (as opposed to 2MB) must be high - how can i monitor this?
I am planning to follow the procedure here:
http://download.oracle.com/docs/html/B13831_01/ap_64bit.htm#CHDGFJJD
The DB is for SAP on a 8CPU/48 core IBM x3950. For some reason SAP documentation does not mention anything about this registry setting or even if Large Page Size is supported in the SAP world.
Part 2 : I notice that more recent Oracle patch sets (example 25) turn NUMA OFF by default. Why is this and what is the impact of disabling NUMA on a system like x3950 (which is a NUMA based server)?
My understanding is Oracle would no longer know that some memory is Local (and therefore fast) and some memory is Remote (therefore slow). Overall I am guessing this could cause a real performance issue on this DB.
-points for detailed reply!
thanks a lot -

Hello
Thanks for your reply. I am very interested to hear further about the limitations of Windows 2008 and the benefits of Oracle Linux.
Generally we find that Windows 2008 has been pretty good, a big improvement over Windows 2003 (bluescreens don't occur ever etc)
Can you advise further about Large Page Size for the buffer cache? I assume this applies on both Windows and Linux (I am guessing there is a similiar parameter for 10gR2 on Linux).
SAP have not yet fully supported Oracle 11g so this is why 11g has not made it into the SAP world yet.
Can you also please advise about NUMA? regardless of whether we run Linux or Windows this setting needs to be considered.
Thanks

Vi memory size verses file size

I have a subvi that does not contain much code data block and front panel objects thus giving a total memory usage of 151kb as shown below. However the file size is almost 2 orders of magnitude bigger. What is the explanation of this?
I also tried to copy and paste diagram to a blank vi and that file was twice the size of the original.
Any idea as to what's causing the discrepancy in numbers and the large file size. I have some empty clusters going in and out of the subvi and I have an imaq create function within the subvi. But the numbers don't add up.
Below is the VI memory use and front diagram showing mostly empty objects. I'd upload the program itself but it's a bit large, hence the problem!
Thanks y'all!!!

I figured it out!!!
It's the "original image" constant that fed into the cluster. It was a constant I created off an image wire in another vi. I guess it carried over the image data when created. I deleted this constant and switched this to an "IMAQ create" function and viola, 35KB file now!!!
Thanks for all your help people. I think it might be advisable when displaying front and block diagram memory, that constants relating to IMAQ images were included. It's not readily identifiable unless you track down the culprit(s)
From this to this

Activity Monitor showing incorrect amount of virtual memory size

Hi,
I noticed that in Activity Monitor that the Virtual Memory size was incorrect.
Does any body else have the same issue?

Ignore that. The method it's calculated works as following:
1. You have the Finder and Safari open.
2. Both programs and no other ones use the content of a single block of data. This block takes up 2MB of RAM or swapfile space.
3. The block is counted as 4MB in the VM size entry because it's being used twice.
Expanding the scenario over many processes and blocks adds up to a VM size figure which is far larger than the actual amount in use or the combined total of RAM and swapfile space.

Large Memory Pages and Mapped Byte Buffers worthwhile?

Hi
I have just been reading about large memory pages that let the OS work with memory pages of 2M instead of 4k thus reducing the Translation-Lookaside Buffer Cache misses on the CPU. However my use case revolves around using mapped bytebuffers on a machine with 32GB of memory and file sizes of 400GB or more for the file underlying the mapped buffer, my program is very memory intensive and causes the OS to do alot of paging, hence my desire for any way to speed up access. Would using large memory pages in linux and the java vm option +UseLargePages have any affect on read/writing data from mapped byte buffers or is it only applicable to data that is always resident in memory?
Thanks in advance

How do I set up iPhoto '11 version 9.2.1 to send emails with medium/Large/actual size? I try sending photos to a publisher and iPhoto automatically shrinks them to about 40 kB. Publisher needs between 0.5 and 7 MB. My ISP has a limit of 12MB

How can I get to email photos at higher resolution?
My "iPhoto" or "Mail" automatically reduces photos to about 40 KB .
My photos, taken with a common Panasonic Lumix DMC-TZ20 include flora which I send to a publisher.
I am fairly new to my MacBook (Mac S X Version 10.6.8). I have been using it for a year.
I found I could not successfully send Large or Full size photos.
A few days ago I downloaded a new version of iPhoto (iPhoto '11 version 9.2.1).
Again, although I get the option of choosing to send small/medium/large//full size photos, it actually only sends them as "Small" (ie about 40kb) which is useless to publish. If I drag a picture onto the desktop (where my EXIF tells me it is full size) then attach it to an email by dragging, againg the sent email is at "small" size ~40KB).
My ISP (Westnet) tells me that their maximum accepted size is 12 MB.
I suspect that I have failed to set up iPhoto for this purpose. (I am well into retirement but, although geriatric, did study University Physics about half a century ago)
