Windows 7 - Large Pages
While I was performing some benchmarks on my W520, I became aware that there is a function in Windows 7 called Large Pages. Essentially setting this policy for either a single user or a group greatly reduces the TLB overhead when translating memory addresses for applications in storage. The normal page size is 4KB. Large Pages sets the page size to be 2MB. The smaller number was useful when there was only a relatively small physical memory space available in the system (Windows 95, etc). However, as the addressable physical page space becomes larger, the overhead for translating addresses across page boundaries starts to be significant. Linux has an equivalent function.
Here's a screenshot of where the setting (Lock pages in memory) is located:
<----------------
The memory bandwidth benchmark using SiSoftware Sandra 2012 showed a performance increase of 2.04% for normal operations and a 2.9% increase for floating point operations. This was with only one user enabled. Enabling all users in the system brought an additional .5% performance increase. PCMARK7 also showed a corresponding increase in benchmark performance numbers.
Thanks to Huberth for pointing me into the SiSoftware Sandra 2012 benchmarking software and the memory bandwidth warning.

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 -
RAC windows 2003 64bit xeon - Large Pages
Hi all
i have 2 node (windows 2003 64bit dual core xeon, 8GB RAM)
oracle recommendet use large pages on 64bit insted LOCK_SGA, but when i use large pages and i set my sga_target=5GB after few minute in EM i see alert (stronicowanie virtual memory) i dont knew how i can write this, mayby swapping.
how can avoid this?
how i can check that oracle use large pages?
meyby some intresting links?

Large pages in Windows / Oracle
Hi,
Has anyone here tried to activate large pages in Windows/Oracle environment?
ORA_LPENABLE = 1
Does SAP support this?
VMware pushes towards large pages.

Never tested it, but what I can confirm is that, at this moment, it is not supported in an SAP environment.

Page break for Smartform with multiple main window on pages
Hi Experts,
I have a requirement for printing 3 pages. The difference among the 3 pages is the main window part.
The main window contains not only internal table, also complicated texts like payment instructions etc.
The requirement is in each page, the data in internal table should be changed, also payment instruction should be changed accordingly.
e.g:
Main Window of Page 1
Part 1 for Internal table
VAT on ITEM ------- 4O-------60,00------0.00%-------EUR
Part 2 for Payment Instructions
Texts for Page 1
Main Window of Page 2
Part 1 for Internal table
VAT on ITEM ------- 5O-------60,00------0.00%-------EUR
Part 2 for Payment Instructions
Texts for Page 2
Main Window of Page 3
Part 1 for Internal table
VAT on ITEM ------- 6O-------60,00------0.00%-------EUR
Part 2 for Payment Instructions
Texts for Page 3
At first, I was using only one page 'Page1' with a variable page_no = 1 as default value, and use program line page_no = page_no + 1 as counter. when page_no = 2, use command for force page break to 'Page1', then under the command, change the internal table and payment instruction texts. when page_no = 3, ...
But I encountered an error saying:
Runtime Errors GEN_BRANCHOFFSET_LIMIT_REACHED
Short text
Jump distance is too large and cannot be generated.
So I created 3 pages, with different main window M_window1, M_window2, M_window3 for each page. In page1, after printing the M_window1, page_no = 2, use command to go to page2, but page2 is never printed. I think this is because only one main window can exist in a smartform? but why smartform allows creating individual main window for different pages? what's the use of such main window?
By the way, what's the use of command for force page break? only work for one main window in a smartform?
Getting back to my requirement, I think I should still use one page and command for page break. I am trying to solve this.
Thanks.
Li Jun Da.Now I am using 3 pages: Page 1, Page 2, Page 3.
Page 2, Page 3 are copies of Page 1 with main window renamed as second window: mw 2, mw 3.
I also created 2 command nodes in main window of page 1: cmd 2, cmd 3.
cmd 2 is for page break to Page 2, cmd 3 is for page break to Page 3.
The second window mw 2, mw 3 in Page 2, Page 3 can be displayed.
Even though, I still can't understand how main window of pages (not 1st page) can work. -
How to keep alignment in Windows LARGE and SMALL fonts
For years, I fought with LabVIEW, trying to keep things looking decent in both Windows LARGE and SMALL font sizes.
By this, I mean Settings - Control Panels - Display - Settings - Advanced - General - Font Size
I love to use large fonts - I run my display at 1600x1200 and it just looks better.
But if you plop an indicator on a panel in LARGE fonts, save it, then open it with SMALL fonts in effect, it looks horrible.
N.I. Doesn't care about this - just look at how ugly their own examples get when viewed in LARGE fonts.
So I developed a method to make the bottom of the label text line up with the bottom of the numerical text, whether in LARGE fonts or SMALL.
Click here for examples. Basically, I turn OFF the SIZE to TEXT attribute and right-justify the label (if on the left of the numeric).
This works OK, except I have just discovered that it depends on the text being the default size.
If I have a 17-pt numeric with a 17-point label, then they both appear as 13-pt when I switch to SMALL fonts - great -- they're still aligned.
But if I have a 17-point numeric with a 16-pt label, when I switch to SMALL, the numeric shrinks to 13, but the label stays at 16, and is thus vertically misaligned with the numeric.
So how can I have a 17-pt numeric with a 13-pt label, and have them BOTH shrink when I switch to SMALL fonts?
I suppose I could use property nodes, and detect the switch myself, but I have 50+ of these on a single VI to do - that would be ugly to watch the labels jumping around.
I suppose I could have two VIs - one for LARGE fonts and one for SMALL, but I don't want to duplicate th
e code.
Any other ideas?

Blog for (mostly LabVIEW) programmers: Tips And TricksIt is true that we don't have a
solution. It isn't that we don't care, but the solution choices stink.
Well, I'll stand by my opinion that N.I. doesn't care - when using the default app font, there *-IS-* a solution - the link in my original post points to a page that I show my employees on how to solve the problem. It is solvable, for the case of using the default font and size. Yet N.I. uses the default font and size, but LOOK HOW THEIR EXAMPLES APPEAR (see attached files). This is how the example software looks, out of the box. These are not ancient examples, either.
It is NOT my opinion that, because there apparently is no solution for non-standard sizes, the stuff looking ugly is NI's fault.
But when a solution DOES exist for standard sizes, why they don't apply it is beyond me. Even some of the LabVIEW dialogs suffer from this.

Hi everyone. I got a envy h8-1513c running on windows 8 64-bit. I went on my windows feature page and I mistakenly unchecked all the features. At this time, no applications or programs were working. I paniqued and I went back to the windows features page and I checked all the features...Unfortunately, it did not solve the issue: I was still not able to run the windows updates and to open files, apps or programs. I ran the BIOS update and when the system restarted to configure the update, the automatic repair started itself. The nb restarted and everything is working fine. Now I'm able to run windows update, open files, apps and programs. However, when I go to the windows features page, it's just blank. . .what can I do to fill it out again. . . does it really matter if it's blank, I mean the nb is working fine so maybe it's not that bad...please help me for this. I have a lot of questions in my mind :-(

Large page format PDF Cropping
Hi I have recently upgraded to CS5. I am using a Mac Quad Core Intel Xeon with Snow lepoard OS.
My problem is that im trying to PDF a large page size from Indesign, i go through the usual chanel of print setup, i click on Manage Custom Sizes
Enter the new size, return to the setup window ensure every thing is to 100 % scale crop mark etc and save as post script. i then take the document into distiller. The output is an A3 cropped version of the bottom left corner.
I have read Snow lepoard is not dependant on the PDF Wrtiter print drive any more? so should i use my Laser printer driver with the bespoke page size? there seems to be little or contradictory information on this subject.
If any one could offer some insight i would be most grateful. ThanksThis is really an InDesign issue and not PDF, but I'll answer.
Use File->Export to create the PDF.
Creation of PDF from Creative Suite applications should ALWAYS be done using Export/Save As and NEVER using printing. -
FM9: Possible to make "fit window to page" the default?
I'm using FM9, structured, on Windows 7. (My company recently upgraded from FM7.0.) In FM 7.0, my documents seemed to remember the last zoom I had set, and if I saved them having set "Fit Window to Page", the next time I opened the document that setting would be in effect.
This doesn't seem to be the case with FM9. Every time I open a document, its window fills the screen, and I need to manually fit the page to my preferred zoom (100 or 90%) from the Zoom status bar menu. There are a lot of options for tweaking preferences for windows - I have not selected to open documents as tabs, for example - and I wonder whether a preference setting is preventing the fit window to page setting from being remembered per document, or whether there is any other way I can make that the default for opening documents.
Thanks very much for your help.
-- garyZStill struggling with this, and the possible confounding factors, like differnet interface preference settings. Some online research I've done seems to point to this being a problem in FM9, that is, setting a default zoom and fit for all documents. There are some third-party plugins that say they can do this... but not for FM9. So maybe the answer is "upgrade to FM 10", but that isn't an option for my department at this time.
Further symptoms:
- If I open all chapters in a book together in a single tabbed window, and explicitly set the first document to Fit Window to Page, I get what I want for that document, but as soon as I choose another chapter in anotehr tab, the window widens (I show a single page only), leaving a lot of gray empty window space. I can explicitly set THAT document to Fit Window to Page, but when I click back on the first chapter I was working on, it opens wide; it has lost the Fit Window to Page I originally set for it. Working that way, any time I change tabs, and frequently when I do operations like changing the conditional text that shows, the window containing all the tabs widens. I would like to prevent that if possible.
- Even when working on individual chapters, if I set one to Fit Window to Page (a setting that held, if I subsequently saved the document, in FM7) the setting is not (consistently, it seems) remembered, and the next time I open the single chapter, the window opens wide, or maximized (23" wide monitor) as if it is trying to give me a two-page view, but I'm only working with one page views (my preference because it's what I'm used to).
- Regardless of how the files open individually (sometimes the zoom and fit seems to hold), when I open a book file, then use Open All Files In Book (having set the interface to NOT open all the files as tabs in a single window), I get this bizarre Time Tunnel effect whereby each chapter opens in a window that fits within the bounds of the previous chapter. If the first chapter opens correctly, say 100% zoom and Fit Window to Page, the second opens at 100% zoom, but fits in the first, the third within the second, and if the book has enough chapters, the last chapters are vertically tiny, not showing more than a line or two of text. So I need to manually rearrange and re-fit them all before I work on them. What a pain.
I have to say, the FM9 interface is awfully clunky. I don't know if it's implemented (partly) using Flash or what, but whole book operations like opening or closing all files, saving a book as PDF, sometimes even just switching the conditional text that is shown generally result in a frozen screen and a title bar that indicates "not responding" for a couple of minutes before FM9 gets it's act together and returns (often with windows resized and zoomed). It can be pretty frustrating to work with, and can really slow me down.
I'm using structured FM, but not DITA - in house designed EDD, probably based on docbook, but I'm not sure. FM9 is completely updated with available patches.
I've tried playing with the different Interface Preferences, to see if that helps - variously having FM open files as tabs to share the same large tabbed window, or turning that off to have them open as individual files in individual windows. I still cannot get Fit Window to Page to hold consistently. It's a relatively minor nit, but it is annoying, and gobbles extra time for me to keep resetting the working environment as I like it. I have set up a workspace for myself, but this doesn't seem to include the zoom settings, only the various palettes/panels and their states and positions.
If anyone knows of or discovers a fix to this issue, your help would be much appreciated.

Error: Java HotSpot(TM) 64-Bit Server VM warning: JVM cannot use large page
Hi,
i recently came across Error Message (coming up in webadmin Log view):
ProcessMonitor: Java HotSpot(TM) 64-Bit Server VM warning: JVM cannot use large page memory because it does not have enough privilege to lock pages in memory
when running Oracle NoSQL on Windows 7 64bit Home Premium system, having 8GB of physical RAM.
I created the store configuration without explicitly passing a value for parameter memory_mb (was set to -memory_mb 0), so that replication group would take as much
memory as possible, which found it's reflection in following line from store log:
Creating rg1-rn1 on sn1 haPort=tangel-lapp:5.011 helpers=tangel-lapp:5011 mountpoint=null heapMB=7.007 cacheSize=5.143.454.023 -XX:ParallelGCThreads=4
I was a bit surprised because of the fact that i definetly succeeded in running kvstore in this configuration, leading to store using 7007MB of memory.
It was only possible to run kvstore when creating store configuration with memory configured to be less than 2GB.
After searching google with error message mentioned above i came across some hints regarding activation of Huge Pages on Windows 7, which mentioned that it could be
done on systems having at least Windows 7 Professional Edition.
But finally i found a more helpful hint, referring to size of windows pagefile. As my machine uses an SSD as system disk and there some notes on deactivating pagefile when
using an SSD, i did so some time ago.
So i activated the pagefile on windows again and after doing so, the store came up without any problems.
Maybe it's nothing new to some of you guys, but as there was nothing to be read about this fact in neither admin nor getting started guide, i just wanted to share this
piece of information with you.
Regards
ThomasCharles,
thanks for clarification, obviously i've overseen that in chapter "Installation prerequisites" of
Admin Guide.
By the way, are there any specific OS related settings, let's say "best practice" similar as it is
referred to in documentation of "classic" Oracle Databases?
Regards

* You changed the page that comes up after a crash - the one which shows the windows and pages that were up before the
crash.
This used to be a real HTML page and it isn't any more. THis choice was pure isiocy consider how peopel used that page every day (try taking to your users for a change).
The pages listed on that 'post crash page' used to be actual LINKS (you could right click them &
manually open them in another tab - and most peope DID that every day). You could also (and I did this a lot) drag a second
copy of the page, into a new tab (to keep track of all the pages I had not wanted to open)
Now the pages are no longer links. You cannot right-click them.
The thing in the probser is no longer a page that I can drag into a new tab.
Roll the version back and throw this one in the bin...and have a good long talk with your developers about the definition of
'STUPIDITIY'
Then I try to type anything in the addres bar it is suppose to repoond with the history of old things I have types in the past, or
search for what I type (and in some cases I think it tyes to convert it intoa URL). However it no longer does any of these
things. When I type in the ADDRESS BAR ONLY, I do not get all of my letters to appear. I have to type into a notepad or
into the search and to copy and paste to go to a URL. Nothing that is typed into the address bad responds normally at all
anymore, and I am fairly certain there are no new addons on this machine at all. It does not matter which things I disable. It
still does this. W of course points the finger back at a change to FIREFOX. I wich I could just sitct with one stable release
forever but the MOZILLA folk thing it is best to force peopel awy from a working broswer release to a horrible one (due to it
being out of date).
FIREFOX 26.0 has 'issues' (ie new *features*/bugs)
1) History is no longer accurate. My Proof? This machine is the primary one for the entire family (the only PC working). It is
logged in with same user every time and never has its history cleared. It now January 7 so I ought to have a list of all of last
months browing available to me.
However, according to FIREFOX history, in all of December 2013, the entire family only went to 51 primary URL's. None of
the official TV sites I use to get episodes are listed. None of the official movie sites I use are listed. The primary URL for
ebay is not listed. Only 1 out of our 4 weather sites that I use (at least once a week) are listed. Only 1 of our 3 FINANCE
sites is listed. There ought to be several; hundred root URLs listed.
Please fix history as this change seriously "blows greasy chunks"
PROBLEM (a stupid change in the new FIREFOX version)
FOr a long time, after a crash you got a useful page (a real HTML page) which gave you a list of all of your last sessions
'winwos and tabs' that were open when the browser crashed. there were certain ways of using this page that are no longer
able to be done.
The old method was wonderful as it had this behavior :
*** The old method for displaying your 'Recovered Tabs' allowed you to :
a) right click an individual item and open it in a tab without getting rid of that lovely window of your previous session of
'recovered windows and tabs '.
2) drag the URL for the entire window of 'recovered windows and tabs ' to a new tab (to make a second copy) so that you
could select just a few of them to open as a group, and stil have the old list handy.
You can no longer do either of these things. The 'recovered windows and tabs ' page no longer has links in it and can no longer be dragged, so you cant select a few of them to use, and keep the rest around for later. NOW - once you choose which pages to open the window is gone forever (can can't get a second copy).
People used to make a copy of the page for later use (with a drag)
we also used to open pages with a right click (which no longer functions
This new method seriously blows big greasy chunks. A parge loss in function has occurred.
Put things back as they were. 26 is full of terrible changes that NOBODY likes. It also has a lot of bugs (history is not reliable at all)(1) Firefox's built-in post-crash page has not been a real HTML page for a long time (for example, from the time of Firefox 22, see: [https://support.mozilla.org/en-US/questions/968212 Want to save LOTS of versions of "Restore Session.xht" from the "oops ..." page for later use]). If you had this working differently with Firefox 25, that might have been created by an extension.
You can check to see whether extensions are disabled or need an update on the Add-ons page. Either:
* Ctrl+Shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Extensions. The disabled extensions cluster toward the bottom of the list. To poll for updates, use the "gear" button above the list and choose Check for Updates.
If you used the Reset feature (or Firefox automatically did a reset due to some problem during upgrading), you will need to reinstall missing extensions. The reset feature creates a folder on the desktop named Old Firefox Data. Do you have that folder? There may be data you can recover from it.
(2) There are many ways for history to get cleared, both internal to Firefox and external. Could you double-check your Privacy settings?
orange Firefox button (or Tools menu) > Options > Privacy
* The "Firefox will" drop-down says Remember History: Firefox shouldn't be clearing history, but an add-on or external software could do it
* The "Firefox will" drop-down says Use custom settings for history: inspect the "Clear history when Firefox closes" setting to make Firefox isn't set to clear history. Also check your add-ons and consider external software.
Firefox normally accumulates months of history. However, some of Firefox's database sizes are based on disk space available. If your hard drive is very full, Firefox might reduce the amount of history stored. -

Beginners guide screwed|Is impossible to edit large pages on the wiki
When you're trying to edit a large page on the wiki you get this message:
WARNING: This page is 40 kilobytes long; some browsers may have problems editing pages approaching or longer than 32kb. Please consider breaking the page into smaller sections.
Firefox can handle the 40kb but not the 107kb of the Begginers Guide for example.
And when you do a change, if you dont preview it you get a shiny blank page instead of the document.
I was trying to add one line to the Oficcial installation guide and ended up breaking it into two parts (i move the apendix to another page) to be able to recover it's contents.
Some other person form #archlinux that was helping me with this issue also accidentally override the text from the Beginners guide, and we can't roll back it. So, any WikiAdmin can roll back the changes on the Beginners guide? and tell us (the normal users) how to edit long pages.
Thanks

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
10394: ./malloc_and_sleep
Address Kbytes RSS Anon Locked Pgsz Mode Mapped File

00400000 6288 6288 6288 - 8K rwx-- [ heap ]
(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.
