How to diagnose large swap usage

Hi,
We have a java application that is connecting to our oracle 10g database. When the application is not connected the swap file usage on the solaris box is about 1GB. But soon as we startup the java application and connect it to oracle the swap usage jumps to a massive 16GB (and stays like that until with shutdown the application - it does not really grow any more)
The application actually looks fine and works without problems - expect the database is hammering the machine with the swap file. can anyone give me some hints at where I can look on the database to try and diagnose what is acutally causing this large swap file creation - in an attempt what is this application doing? At the moment I am confused as to what could actually cause this.
thx.

Hi, I'd use the iosnoop, iotop, rwsnoop and rwtop commands available in dtrace package (eg. http://users.tpg.com.au/adsln4yb/DTrace/dtracevstruss.html). It can tell a lot about i/o operations, also according to swap. But it only applies to the OS, I can't help you with the Oracle...

Large pool usage and advanced queueing

Hello All,
I'm using Oracle 10.2.0.3 under Linux IA 32Bits.
I've got a big problem with my large pool that keep increasing as I'm using Advance queuing. After a while, errors 4031 are raised.
Can someone explain how to monitor large pool usage. Espaecially I would like to know wich process/ session consumes large pool.
Thanks in advance for your help

Whilst Daniel does his 'Twenty Questions' trick on you (he has a valid point: OS and Oracle Version are ALWAYS useful to know... but there's no need to pin it down to four decimal places for such a simple question!), I'll have a go at actually providing an answer.
A number of things might be going on.
First, do a google search on "joxs heap init" and you'll find suggestions that setting or increasing the JAVA_POOL_SIZE can fix the problem. See this for example, which has exactly your problem:
http://www.mail-archive.com/[email protected]/msg36154.html
Second, a lot of things that would use the Large Pool if it exists can instead make use of the shared pool if it doesn't -but they fragment the thing mightily as they do (the Large Pool was invented precisely to provide a chunk of memory that doesn't age out, only gets re-used and thus never fragments). So something (an RMAN backup, for example) might work without a large pool, if there's room in the shared pool; but if the shared pool is already fragmented or tight, then it will error with a 4031. Allocate it a bit of Large Pool, however, and it prefers to use that, finds the memory it needs is now available and therefore works fine.
The large pool is used for RMAN, shared server, I/O slaves and parallel slaves. Who knows precisely what's going on in an export that might be touching on at least 2 of those things without you explicitly asking for it to do so?! I mean that it's possible it's doing a bit of 'internal parallelism' to make itself efficient, for example, and failing to find the memory it needs for inter-parallel-slave communications. Just a possibility and a bit of speculation on my part.
I suppose the next experiment would be: take Large Pool back down to zero and then set Java Pool to 15M instead (note you should really be allocating in units of 4M these days, though Oracle will round up anyway).

Large swap file (900MB), but no pageouts

My MacBook Air 13" with 4GB of RAM accumulates a large swap file over time, but pageouts are 0 (page ins: 1.1million). Anyone know why? Is it possible to see which process/application currently have pages stored in the swap file?

Sorry to dig this old thread up, but I am seeing an identical behavior to the original poster, and I just wanted to say—you did an excellent job of explaining how page ins can be very large with no pageouts, but I don't think this explains the real mystery, which is that there is a large amount of swap space, and a large amount the system says is used, but there are no page outs. You have not explained how a swap file gan grow in usage with no page outs, and if I understand things correctly, this should not be possible.
I'm having the same issue on my new MacBook Pro with Retina display. I have 16GB of RAM and for the most part I don't use more than 4-6GB of that—I bought it for the occasional times I need to do a lot of VM testing, but I haven't needed to do that yet. I consistently see my swap usage grow to be as large as 2-3GB with a total size for all the swapfiles in /var/vm being 3-4GB.
I don't need the space, and the system isn't slow or anything. I just want to know how this is possible. I have been using Mac OS X for 10 years now, and working on linux servers for 5 years or so. I've never seen swap usage be more than 0KB when there are no page outs.
I've attached some screenshots of what I am seeing:
Screen capture from Activity Monitor.
Screen capture from Terminal executing 'du -hsc /var/vm/swapfile*' to tally the total size of the swapfiles.
I should note that it tends to take a day or two of use to start to see this, in a series of sleep cycles here and there. I put my laptop to sleep at night as well as to and from work, etc. It probably sleeps/wakes 5-7 times a day in all. I tend to notice that the usage creeps up, starting atound 50 MB, then I will notice it being a few hundred some time later. It really makes me wonder if this has to do with some kind of discrete vs. dedicated graphics switching or something, perhaps a very low level operation that is somehow avoiding getting counted by the system's resource tracking facilities. I have no idea, but I would love it if there were someone out there who could explain it or point me in the right direction.
Thanks for your time.

Large Swap file

Model Name:    MacBook Pro
Model Identifier:    MacBookPro6,2
Processor Name:    Intel Core i5
Processor Speed:    2.53 GHz
Number Of Processors:    1
Total Number Of Cores:    2
L2 Cache (per core):    256 KB
L3 Cache:    3 MB
Memory:    8 GB
Processor Interconnect Speed:    4.8 GT/s
Running the latest version of Parallels and Windows 7 64 bit.
Using the Activity monitor I find that I always have a large swap file (even when parallels is not running), a huge amount of inactive memory and a very small free memory. It slows down my system. Any suggestions?

First, upgrade your system to 10.6.7 or 10.6.8. Second, large swap files don't necessarily mean a thing. You might see the following:
About OS X Memory Management and Usage
Reading system memory usage in Activity Monitor
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in 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.
Bear in mind you are running Parallels and a VM concurrently with some other OS X applications. Too many concurrent applications will result in using too much memory and increasing swapping.

How to diagnose flickering exported JS animations from Flash CC?

Quick stats on my system:
Macbook Pro Retina 2012 running OSX 10.9.3
Flash CC 13.1.0.226
I'm not experiencing an error so much as a lack of understanding about how to diagnose Flash CC JS export issues. Here's the backstory:
In 2012, my company started working with an contract sprite artist. I was using the CS5.5 Creative Suite, and we were exporting normal png sequences from Flash for use in the game. After about 8 months, my cofounders and I realized that we could both reduce the load time for the game and also allow our artwork to be dynamically scalable by switching to JS exports of our art rather than the raster sprite sheets. Here's the blog post we wrote about it: http://blog.codecombat.com/hacking-our-way-to-vector-artwork-in-html5
At the time, I didn't have Flash CC, and was reliant upon the CreateJS plugin to export the required JS files: CreateJS Developer Center | Adobe Developer Connection After another month or so, our contractor upgraded their version of Flash and we started having compatibility issues reading FLA files, so I upgraded as well. After doing some reading, I concluded that the CreateJS plugin was now incorporated into Flash CC as the HTML5 doc type, which was confirmed when I checked out the publish settings and resulting files.
This is all a rather long winded way of saying that we have legacy artwork created with an older version of Flash but are now importing all of our artwork from JS files.
Fast forward to today and we have two big issues:
1) We can't figure out how to reduce the filesize of JS exports. As discussed in our blog post, vector artwork has upsides and downsides. One of the downsides we've found is that complex art that uses a lot of shapes ends up being substantially larger (in terms of filesize) than the appearance might otherwise suggest. Raster exports skirt this because a pixel is a pixel, but vector exports scale with the complexity of the source FLA. I'm not a Flash expert, and when we get files that are particularly complex, Flash either runs out of memory exporting them to JS files or we get files that are far too large to reasonably use. To be clear, the "out of memory" error isn't a problem because even if Flash finished the export, the resulting files would be too large for us to use (plus, I've done some digging and found a tutorial for correcting the out of memory error). Our artist is not familiar with the intricacies of the JS Flash exporter, so when we get a file that's too big or breaks the export, neither of us can really figure out a way to correct the problem. We have three questions in particular:
     a) Where can you view shape data that Flash is going to write to the JS files?
     b) Is there any way to edit said shape data inside the Flash CC interface?
     c) Is there any way to optimize shape data in Flash? For instance, in Photoshop, you can flatten images and export a psd with 500 layers as a single JPEG, is there any way to do something similar to shape data in Flash?
2) Exports frequently break in weird ways. Many of the sprites that we created a year ago haven't needed to be re-imported into our game engine for some time. But every once in a while, I need to go back and fix, improve, or tweak an existing sprite, and then I run smack into the issue of reconciling files that were created without thought to JS exports with our current system. Just last week I was running into this issue in a big way and I made a screencast for our artist (since we work remotely) that I hoped might give him a better idea of the problem: Flash Errors - Treasure Chest, Flippable Tile - YouTube
The two files mentioned in that screencast are both old (treasure chest) and new (flippable land tile). We have a few questions:
     a) Why are the treasure chest frames "flickering" in the html5 preview? The problem doesn't appear inside Flash and is inconsistent between files. There are two FLA files: one in which the treasure chest is empty, and one in which it's full. The empty animation doesn't throw any errors, either when converting to the HTML5 doc type or on export, but the resulting animation flickers. The full treasure, on the other hand gives me 21 lines of these errors when I do the conversion (not when I export): "Blend Modes(Layer) is not supported in HTML5 Canvas document, and has been converted to Normal in an instance of Movieclip <Path>." The result in both cases is the same: the animations flicker, and neither our artist nor us can figure out why, or for that matter, even begin to troubleshoot it. This SO issue seems to describe the problem, but was never resolved, and I can't find anything else that seems to address it: CreateJS Publish of Flash Project Flickers - Stack Overflow
I've uploaded the files involved to a public dropbox folder which I think you'll be able to access (Dropbox seems to be having some problems at the moment): Dropbox - flash_debugging
Since my questions are fairly involved, and my goal is to gain a better understanding of the UI, not simply resolve an error, I'd be happy to pay for someone's expertise/time in getting me up to speed. You can get in touch with me at george [at] codecombat.com

Hi George,
I have taken a look at the files full_treasure_chest.fla and flippable_land.fla that you have shared via drop box and found that they both uses blank keyframe(s) followed by Keyframe(s). This was an issue and has been addressed in the latest release Flash CC 2014 (released on 18 June, 2014). Can you please install the latest build 14.0.0.110 and try this out?
Thanks!

Unexpected Swap Usage in Oracle RAC

hi Experts,
we are running 2 node RAC 10gR2(10.2.0.4) on AIX6.1. we have 196G of physical memory in each and SGA is 144 and PGA is 32 n remaing is for OS on each node. we also have configured SWAP space of 20G . we have 2 physical Standby in single instance one is with LGWR and other one is in ARCH mode. now problum is both nodes shwing more than 50% of Swap usage. which is indicating wrong as SGA and PGA advisor is showing adequate settings of both parameters . so can any one tell me what may be the reason for this memory leakage . one more thing i must add here is we recently shift our RAC from other Servers . but source and destination both are of IBM.

I'm not an AIX guy at all, but the first thing that came to my mind is large page support. Have you implemented large pages?
Also, it didn't take much googling at all to find:

Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book. Cannot turn these off. They repeat several times per session and every time computer is used. How to diagnose this

Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book. Cannot turn these off. They repeat several times per session and every time computer is used. How to diagnose this?

First, uninstall "SuperTV" (whatever that is) according to the developer's instructions. It isn't working and it's filling the log with noise.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
PLEASE DO NOT INDISCRIMINATELY DUMP THOUSANDS OF LINES FROM THE LOG INTO A MESSAGE. If you do that, I will not respond.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

How to diagnose dead battery vs. something more serious?

I'm in the 11th month of ownership of an MBA, purchased brand new last year. 128MB model.
My battery, I believe, is dead but I'm not sure how to diagnose the matter.
Here's what's lead me to this conclusion:
MBA charger light stays off when plugged in (not dim, but off).   I've had the dim light issue as well, earlier this year, and Apple replaced the charger. This time, however, the light stays completely off.
Battery icon in top right corner tells me that no charger is plugged in. The icon is in battery mode.
Battery charge keeps decreasing steadily in % value despite charger being plugged in, indicating that battery is continually discharging.
My wife has an MBP, and I've used her 85W charger on my MBA with the same result... i.e charger light stays off.   I know that the MBP charger is in good health as it charges the MBP with no issues (orange light).
I've used my MBA charger on her MBP, and it charges the MBP just fine!!! (orange light)
I've done an SMC and NVRAM reset on the MBA, which hasn't affected the situation.
Since I'm on 15% charge on the MBA, I've shut it down and have booked an appointment with Apple to have it looked at.
In the mean-time, I'm hoping to get some clues from fellow MacBook users on this forum.
I've read somewhere that if it is indeed the battery that's faulty, then once the charger is unplugged, the MBA should turn off immediately. This isn't the case for me... I'm able to run off battery (whatever tiny amount of charge I have left) with the charger unplugged.
Hence, I've ruled out the charger being faulty. I'm not so sure that the battery is faulty. I'm thinking the issue might lie elsewhere... maybe the magsafe connector on the MBA?
I should also mention that when I opened the lid on the MBA earlier this evening, before noticing this charging issue, the screen flickered brightly once. The screen looked and operated normally after the flicker. Not sure if there's a connection. I'm beginning to think there is.
I should also add that, even though the MBA has been a pleasure to use, the past 11 months haven't been trouble-free... which adds to the suspicion that the issue might indeed be somewhere deeper.
A brief history of "issues":
About a month or so into ownership... my fan, one day, decided to suddenly spin up to full RPMs and stayed at that speed for an eternity. I'm used to the fan speed steadily going up in direct relation to the CPU temp.   However, the CPU temp this time was 35C the entire time (according to iStat Menus)... i.e. the MBA was "stone cold". It made no sense for the fan to be on full-blast. In addition, I had nothing running. No intensive software. Not even Safari. Just "Finder".   Turning the MBA off naturally caused the fan to stop. However, the moment I powered it back on again, the fan came back on at full speed again.
An SMC reset fixed the issue, and I was good to go. This issue occurred again a few months later, but I solved it right away with the SMC reset.
After another month or so I noticed, while listening to music via headphones that were plugged into the MBA, that I could hear an electric "hum" in the headphones. Then all of a sudden the hum went away. I discovered that the hum was present only when I physically touched the metal case of the MBA and went away as soon as I removed my hand.   I mentioned this to a Genius bar... err... genius and he seemed perplexed. He wasn't able to offer an answer.
I've also noticed that when the MBA is charging, and I run my finger-tips over the MBA's metal surface that I feel static. When the charger is unplugged, I no longer feel the static.   Again the genius didn't have an answer. He probably thought I was weird.
I'm thinking my MBA might have "grounding" issues, but am no expert in this field.   With the latest charging issues, however, I'm leaning towards this theory again.
Thoughts are welcome.
Regards
MrAir

No clues, it is very apparent you have a hardware problem and it is not the battery. If it was the battery the computer would not be running as you say the charger is not charging the battery.
There is a charging curcuit that has more then likely failed. You have done the correct thing, take it in and get it fixed before your warranty runs out.

How to upload large file with http via post

Hi guys,
Does anybody know how to upload large file (>100 MB) use applet to servlet with http via post method? Thanks in advance.
Regards,
Mark.

Hi SuckRatE
Thanks for your reply. Could you give me some client side code to upload a large file. I use URL to connect to server. It throws out of memory exception. The part of client code is below:
// connect to the servlet
URL theServlet = new URL(servletLocation);
URLConnection servletConnection = theServlet.openConnection();
// inform the connection that we will send output and accept input
servletConnection.setDoInput(true);
servletConnection.setDoOutput(true);
// Don't used a cached version of URL connection.
servletConnection.setUseCaches (false);
servletConnection.setDefaultUseCaches(false);
// Specify the content type that we will send text data
servletConnection.setRequestProperty("Content-Type",
+"application/octet-stream");
// send the user string to the servlet.
OutputStream outStream = servletConnection.getOutputStream();
FileInputStream filein = new FileInputStream(largeFile);
//BufferedReader in = new BufferedReader(new InputStreamReader
+(servletConnection.getInputStream()));
//System.out.println("tempCurrent = "+in.readLine());
byte abyte[] = new byte[2048];
int cnt = 0;
while((cnt = filein.read(abyte)) > 0)
outStream.write(abyte, 0, cnt);
filein.close();
outStream.flush();
outStream.close();

How to reset the military usage value in GTS Business partner

Hello Experts,
Does anyone know how to reset the Military usage value='2' to blank on the Business partner within GTS?
I tried putting a blank there, clicking on the accept entries button followed by saving the Business partner.
It does not seem to work this way.
Does anyone know if it's SAP bug for not having blank as one of the allowable values for the usage except when it's that way while newly created?
The GTS implementation details are as follows:
Any help with regard to this will be much appreciated......
Thanks,
Prashant.

Prashant,
As I already informed you, it is not possible to re-set the indicator to <blank>.
From the program code, I can see that the usage indicator is only transferred from the feeder system during the creation of a customer partner. The value in GTS is set either to '1' or '2' during creation, and cannot be changed by any subsequent data transfer from the feeder system.
I think that logic is related to the fact that usage records may be created for multiple Legal Regulations, and those records may then be changed individually by the user in GTS. On that basis, it would not be reasonable to over-write the values by re-transferring the customer from the feeder system.
Regards,
Dave

How to diagnose software / driver / video card issue?

My computer has been freezing up on a regular basis for the past few weeks . . .
I initially assumed it to be a bad stick of RAM, but I was able to reproduce the lockup with each stick individually.
I tried downgrading the kernel (but not Xorg or nvidia drivers), and that didn't fix anything.
At this point I don't really know enough (especially related to Arch specifically) as to how (which) log files to check for a reported error and issue.
The main issue of locking up occurs when I'm watching something on VLC at full screen. It's exacerbated with browsing or doing other stuff at the same time.
After a lockup I don't know if I should be checking journalctl / dmesg / Xorg.log / htop / etc . . .
Any advice / direction of stuff I can be checking after a crash would be MUCH appreciated. It really sucks not being able to use my PC like I used to.
If it help any my board/RAM are ~6yrs old, but the gfx card is new as of this year (I am using the regular nvidia drivers and multilib): EVGA 02G-P4-2645-KR GeForce GT 640

I tried various video drivers; nvidia 304, 325, 331 and nouveau, but in any case the system freezes after playing video for half an hour or so. The problem is more rare on a 32 bit installation than 64 bit, so perhaps you could move from 64 to 32 bit?
sorry for your troubles! i am not sure what the exact issue is, but i am on nvidia w/ video troubles as well . . . i have been running atop 24/7 and notice high r/w use of my disk at times when playback starts to stutter . . .
i haven't had a full-on lockup in days, but have still had one in recent time. i am not really sure how to trouble shoot this further.

My messages usage says I have 2.9GB of (saved) Messages. Thing is I have not 1 saved message, I delete them all. How can I clear this usage?

Firstly you DO NOT have to do a factory reset / wipe device, it is simply not required to get the space back!!
Mine had 3GB and I just got rid of it all, here is how:
METHOD ONE:
Make a backup in iTunes
open iBackupBot (Google it)
Go to the relevant backup
Click on Multimedia File Manager and click on the other Multimedia files tab
Sort by filename by clicking the Filename tab
Find MediaDomain/Library/SMS/Attachments and highlight all of them, then press delete. You can also click to export to a folder of your choice, if you want to save them that is.
Then go to System Files>MediaDomain>Library>SMS>Attachments
They will be all listed here, highlight them all and press delete
Then just restore that backup using iTunes!
Tadaa! Space recovered, your messages are still there but without the attachments! METHOD TWO:
Backup your device in iTunes and then to iCloud
Go to Settings>iCloud and toggle Documents & Data to OFF
Then do a 2nd backup to iTunes and iCloud
Then restore the device from iCloud and the message attachments should be gone, turn Documents & Data back on again in the settings
PLEASE NOTE: Method two is a much longer process but some users may feel more comfortable with this method.
P.S You may want to make two backups in case you get any of the above steps wrong, but it is simple to follow the above and not do anything wrong!
P.P.S You could also just go through every single conversation and delete the attachments one by one, but if you have hundreds or thousands of attachments, this will take a VERY LONG TIME!!!

Does anybody know how Oracle load large N-Triple file into Oracle 11g R1?

Does anybody know how Oracle load large N-Triple(NT) file into Oracle 11g R1 by using sql*loader according to their benchmark results?
Their benchmark results indicate they have over come the large data set problem.
http://www.oracle.com/technology/tech/semantic_technologies/htdocs/performance.html
It means they have loaded LUBM 8000(1.068 Billion+ Triples) into Oracle successfully, but there is no detailed steps provided. For instance, 32-bit or 64-bit platform they used, only one NT file being used corresponding to one dataset or several NT files?
Is there any exception occured during the loading process if the NT file beyond 60GB? When using jena to generate NT file against LUBM(8000), the size of the NT file would definitely beyond 60GB.
We are dividing such large NT file into several small ones? Is it a good approach? I'm hesitating to do so!

A Linux 32-bit platform was used for bulk-load of LUBM-8000 1.106 billion (before duplicate elimination) RDF triples into Oracle.
Multiple gzipped N-Triple files were used to hold the LUBM-8000 data. zcat was used on all these files together to send the complete data into a named pipe. SQL*Loader used this named pipe as the input data file to load the data into a staging table in Oracle. Once the staging table was loaded, the sem_apis.bulk_load_from_staging_table API was used to load the data into Oracle Semantic Store.

Thanks.

like Diavonex stated, you could use an app created to check the battery percentage
but remember, google is your best friend =^)
