Unabel to processes application with high memory image

Hello every one
In one of my application i am loading 8mb image into 2d picture control and i am doing some operations on it .
This is working perfectly but when i am using high memory image like 30mb the performance i.e in terms of speed got slowed down .
So how to increase the speed of the application

Nagaa,
When you write "mb" do you mean megabytes? The typical usage in English is MB. Lower case letters technically would refer to millibits which of course does not make any sense.
A 30 MB image, assuming 4 bytes per pixel, is 7.5 megapixels. In a square image it would be >2700 pixels on a side. Unless your picture control is that large - which is larger than most screens - the data has to be reduced to the number of pixels in the control. LabVIEW or the OS or both will do those reductions, but you have no control over how much time it will take.
The other thing which can slow processing is creation of extra data copies in your operations.
Without seeing your VI, I cannot make specific recommendations. In general:1. Make the image size match the picture control size and 2. Avoid extra data copies.

PSE8 Full screen view with high-res images

The Full Screen View in PSE8 doesn't seem to cope well with high-resolution images, eg from a full-frame DSLR (eg my Sony A850 with 6000 x 4000 px).
After selecting an image in Organsier and starting Full Screen View the first image is displayed successfully, but clicking the button to move to subsequent images soon results in a "cracked image" symbol. (It's unrelated to the image though - closing FSV, selecting the suspect image and restarting FSV displays it properly).
I get the same symptoms with JPEG and RAW images, and on two Windows PCs. One's XP with 1.5GB, the other is Windows 7 with 8GB.
I've tried maximising the RAM available to PSE8 (in Editor preferences), but it makes no difference.

Here is the solution under Windows 7 64-bit with Photoshop Elements 6 for the new Entry "MaxImageSize":
The Registry-Entries for 32-bit-Programs are saved in
HKEY_LOCAL_MACHINE ... Wow6432Node ...
QWORD-32bit 42C1D8000000
(Hex 1120000000 or Decimal 73551314944)
for a JPG-File up to 10.000 x 10.000 Pixel

Your tip in Printing in Indesign--working with high quality images

Hi everyone,
I am very curious about what the other professionals' idea about printing and using Indesign to print.
I am working on a project that with high resolutions of model and product images together.
Since I had to move elements on the layout. Model and product images are in different layers in Indesign.
I used Indesign to combine those images together to create ads for magazine.
However, I was told that it would be "SAFER" to combine those images together FRIST in photoshop.
he thinks the process should be that:
---Having a flated image of model and products in photoshop first
----then bring that one image in Indesign.
----This way it would insure the color will be right.
What do you guys think?
The places I worked in the past, has not done stuff like that.
I feel like ...colors aren't something we could control when magazine uses their own printing vendor.
What is your process to ensure the color is right when priting a combination of different high resolution tiff files?
Thank you very much for your time and knowleage.
Lori

Assuming you have some sort of color management in place, I would continue to do it the way you are.
But let's say you did want to follow this fellow's advice. Here's everything I can think of.
Putting the models and products together on one Photoshop "page" can wind up making the PSD file very big as there may be spaces between the models and products.
Never, ever flatten that Photoshop file. There's no need and makes a very complicated workflow if you have to make any changes.
You're right about the magazine printing process taking over color.
What are you sending the magazine? A PDF? There's totally no need to flatten in Photoshop then.
The art is flattened in it's own way.
I'm also assuming that your prducts and models are close to each other

Develop EXTREMELY slow with high ISO images

I imported a set of images at 200 iso and developed them (exposure, fill light, etc) with no problems.
Then I imported a set of images at 800 iso and when I attempt to make adjustments in the Develop module it's almost impossible. I'd hover over the slider and then get the spinning beach ball, move it slight and again the beach ball and move it again and beach ball. No preview update and the computer's fans go on and it's maxed out on processing power.
I have rebooted, and deleted those images from the catalog and rebuilt the catalog, fixed permissions, etc. I went back to some older images that were 100 iso and 800 iso and I get the same results.

Any ideas? I'm back to using v3 now until it's figured out.
Thanks,

Try these steps.
Open task manager
Click on processes tab. You can see all the apps and processes that are consuming memory.
Click on top of column showing the memory. This will arrange them in ascending or descending order of how much memory is consumed.
Find the ones which is consuming maximum memory
Uninstall if you don’t need the program or app. Re-configure or re-install the software or app if it is an important one.
Hope it helps.

Working with High size image file.

I am working with high image file . I have to work for iage more than 3000x6000 dimensional. Is it possible in AS3. In some blog i came to know that AS2 could not support more than 2880x2880. Please let me know if you have any experience about working in high dimensional image .

i answered this on another thread. please don't cross-post.

Correlation of spot removal with high memory faulting.

I dont know if the below task manager capture is readable as uploaded, but it shows LRs page faults while in the middle of high spot removal wait time. Specificaly "Page Fault Delta", but also note the large page fault total. Notice there is no load on the CPU. And notice how little physical memory LR is using when there are 12gb abailable. According to this, the application spends all its time waiting on unneeded disk access. It is just sitting there churning on swap memory while its little blue circle spins. I dont see how this can be anything but a design flaw of some sort or perhaps a compiler problem. If so, this should be relatively easy to correct.

I have an OCZ 120 GB RevoDrive on order for this very purpose. This is a fast drive. It will be the D: drive and not hold the OS so that it can be replaced easier since I expect it to wear out faster. It will contain swapfile, catalog & RAW cache. Both C: and D: will be SSD so there there should be no part of LR that relies on spinners. After I get it installed I will report back my findings --probably next week.
The image (+ edit steps) that causes the above condition is very reliable in doing so (as are others) , and I will test it with the new drive. If it fixes the speed problem then I fully expect the task manager show the same page fault data, --if so that will represent a duplicatable bug with a finger pointing in the direction of the problem.
During the spot removal delay there I see no, or very minimal processor activity. According to my screen shot --it is simply waiting on I-O. 3.4 is better, but it appears to not have addressed the core problem, which seems architectural (I've seen the same problem with gradients as well). If I had to guess, this looks like a loop or class of internal tables that are being needlessly forced to swap, only to be accessed shortly thereafter.
Whatever it is, the following is unacceptable, and I can duplicate it at will:

Best way to replace contents of a layer with higher res image

I can do it, but I was wondering if there is a better way.
Large PS file (CS6 and CC) half a dozen texture layers using low res images. Several have blend modes, transparency and even masks. I now have the same images in high res. I want to replace just the image, but not lose my blend/transparency, or masks.
Any thoughts?
Do I bring in the high res layer, copy the mask over etc? Then delete the original?
Max

Try this.
Convert the low res images to Smart Objects. Layer > Smart Objects > Convert to Smart Object.
The replace the contenst of the smart objects. Layer > Smart Objects > Replace Contents...
This way you can replace the low res images with the hi res versions. Provided they are the same crop and aspect rarion your mask should be fairly good to go. I say fairly good as you may have made some adjustments (eg. feathering) based on the resolution.
The blend modes and transparency will be unaffected.

Problem in Webcenter Portal application with High Availability changes

Jdeveloper Version: 11.1.1.5
JROCKET
MDS is pointing to IBM/DB2 database.
Weblogic Domain 10.3 with 1 cluster - 2 manage servers.
BigIP - Load Balancing
Database: IBM DB2
I am facing below issues in webcenter portal application after making high availability changes.
1. "A connection to the server has failed" Status - 12152
12031
404
2. Because of Inactivity, session is timeout - ADF_FACES_30108 exception.
The above exceptions are occuring randomly in the application. It occurs either at login page or inside the application clicking on any link/button.
I have made high availability changes as per the below blog:
http://rimmidis.blogspot.com/2012/02/adf-application-running-on-clustered.html
Any help is really appreciated

Fixed "Because of Inactivity.." popup message by adding more tokens. The PS4 Webcenter portal application default value for CLIENT_STATE_MAX_TOKENS is 3, we increased to 15 that fixed the popup message.
There was another popup message "Connection to the server failed, with status = 404, 12152..., which resulted in a bug in the product. The PortletServletContextListener was throwing classcastexception and that was causing this popup message.
Once again, we have noticed these popup messages only when we tried to make our application high available.

Exchange 2013 issue with High memory Usage on Mailbox server post SP1 update.

So we have been chugging along fine since Feb 2 2014.
I performed a migration from 2010 from the UK to the US doing "incremental" mailbox moves. (get in contact with me if you want to know how. But we moved 400 Mailboxes averaging at 2gb a piece from the UK to the US, over the transcontinental link.
& then the weekend of the final, had everyone & everything done by the end of the cutover weekend)
Any woot.
So I applied the 2013 SP1 a few weeks back, & have intermitantly been alerted to the memory spiking over 95%. For me (and for any exchange admin) when i get those types of alerts i drop everything & run to the nearest PC to see what is going on.
Now the first & second time, it was an issue with logs filling up the drives, & my clean log script not running to remove any logs older than 30 days. But since then it has been legitimate 95%+ memory usage.
For the most part its been 95-97 max, with 1 or 2 times hitting 98. After some time, the memory does drop back down to 94.
this is ....umm "fine" however it is becoming a nuisance, since most of the time it corrects itself. What i dont want to happen is get into the groove of saying "ah bah! its nothing" & letting it go.
the server has 16gb of memory in it, it is the Mailbox server (CAS /Frontend is on a seperate server)
below is a screen shot, so i know the Storeworker grabs whatever it feels like grabbing, however it does NOT EVER release memory. I also see the NodeRunner.exe (2 of them) is always around 900 almost a MB
now if i could somehow get the first 2 Storeworkers to drop down to 900ish, then that should alleviate my memory issues.
what I am m looking for is some type of "magic bullet" to put my memory issues at ease..

thats the problem & seems to be a misconception.
Exchange NEVER releases the memory when other things need it. As the users state in your thread you linked. (i came across that early in my search for a resolution). An example is if another admin & myself log into the backend server at the same
time & begin clicking around opening things, etc..Memory will go to 100% which = No Buenos.
There are numerous post all over the internet from people who say it releases, but them 5 more comments to that 1 saying that it does not.
I know what the process's do, however it seems like the SP1 has increased memory usage, as typically the Store.exe would only grab about 900-1000.
in terms of the noderunner, once again i know its role, however we are now 2 months+ live on 2013 post migration, I do not think it is still indexing all those emails.
all DB's report healthy.

SQL Developer High Memory Consumption 3.2.20.09.87

Hello,
I have been using SQL developer for quite some time and had initially had problems in the past with high memory consuption when I use this tool.
I have received and applied advice from this forum and while it had helped a little, the majority of the high memory consuption remained an issue.
I finally got more time to dig around and try to specifically isolate where the problem seems to be coming from and here is what I found.
*1)* I have removed the Check for Updates feature
*2)* I have turned off many of the extensions except for DBA Navigator, Real Time SQL Monitoring, SearchBar and Snippet.
*3)* When I start a fresh SQL Developer Session and initiate a Oracle Connection the application consumes roughly 148 meg fo RAM
*4)* When I open my Windows Task Manager and watch the memory allocated to SQL Developer I notice it goes up when I move my mouse over the SQL Developer tool and When I run through menus at roughly 5k a second or so and the memory is never released back to the system.
*5)* When I run a Large SQL to the grid the memory jumps by about 100 meg or so and will continue to do so every time I repeat the SQL until SQL Developer consumes roughly 748 meg of RAM.
*6)* 748 Meg of RAM seems to be the number when SQL Developer (with one Oracle connection) no longer continues to consume more and then not return the memory to the system.
Is there a way to have SQL Developer automatically clear up it's active memory usage without closing it down and restarting it?
Why does SQL Developer continue to consume more and more memory just from moving your mouse over it and/or by navigating menus?

Aces!!! You nailed it Gary...
Thank you.
I applied fixed noted in Re: Reduce SQLDeveloper memory footprint with JDK 1.7
For others, to summarize my changes.
product\11.2.0\client_3\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf
AddVMOption -XX:+UnlockExperimentalVMOptions
AddVMOption -XX:+UseG1GC
AddVMOption -XX:MaxGCPauseMillis=50
AddVMOption -XX:GCPauseIntervalMillis=200
AddVMOption -XX:MaxPermSize=128M
AddVMOption -Xms50M
AddVMOption -Xmx384M
AddVMOption -XX:MinHeapFreeRatio=10
AddVMOption -XX:MaxHeapFreeRatio=10
product\11.2.0\client_3\sqldeveloper\ide\bin\ide.conf
comment the following two lines as shown below
#AddVMOption -Xmx640M
#AddVMOption -Xms128M
Now SQL Developer runs at roughly 500 meg.
I guess the only thing I have left to ask others reviewing this would be if there is a way to get these memory values down without having much adverse impacts on SQL Developer based on newer JVM switches/functionalities.
The posts that drove these changes are old from a technologoical perspective :) 2010.

SA520W - High memory usage, possible fix in 2.2.0 firmware?

As suggested by Thomas Watts, I'm starting a new thread to discuss the new SA520W firmware (2.2.0) and a possible resolution to high memory usage I'm experiencing on my network.
My current setup is: 16Mbit DSL > SA520W > SA300-10, all with stock settings (no fancy VLAN's etc.)
I have 4 CentOS 5/6 servers and a Windows 7 Ultimate station connected to the switch. I use CIFS to connect from Windows station to the other Linux servers and send large files. I currently notice the following behavior:
When the file transfer starts, the Intel 1Gbit NIC is nearly saturated, hitting 115MB/sec. After few seconds, the data transfer comes to a halt and the transfer speed drops to around 50MB/sec. If I check the memory usage before the file transfer, it is approximately to 50-60% (on a fresh router reboot). Every time I send large files to other machines, the router memory consumption increases and it does not lower after a reasonable delay. I end-up with high memory near 90% and the only solution I have is to reboot the router in order to bring it back to 50%.
Now, Thomas told me that this is simply a cosmetic issue, the memory is not actually 90% used. Yet, when the memory hits this threshold, I'm not capable to send files are normal LAN speeds I'm used to. Rebooting the router allows me to send only ONCE (and for few seconds) data at the expected LAN speeds.
I would apreciate any input from Cisco engineers as well other users who experience the same issue. I would also like to know if any related work was done into 2.2.0 firmware and when we expect to have it released to users.

Floren Munteanu

Hi Tom,
See below the answers.
Are you currently running the 2.1.71 code?
Yes
Are you using IPS?
No, the LAN is for internal use (no external users allowed)
Are you using Protectlink services?
No
Hardware wise, I did not changed anything on machines. All boxes have dual Intel EXPI9301CT NIC's (LACP was planned) but I currently use single connections for sanity reasons (disks won't allow greater speeds anyway). Previous to Cisco, I used a Netgear ProSafe router + switch which did not encountered the issues I mention. Honestly, at first I thought I'm dealing with some stupid disk issues on Windows. So I ran a quick test and the stats are proper:
> winsat disk -drive c

> Responsiveness: Average IO Rate              2.12 ms/IO         6.9

> Latency: 95th Percentile                     32.720 ms          3.0
> Latency: Maximum                             118.231 ms         7.6
> Average Read Time with Random Writes         13.346 ms          3.7
> Total Run Time 00:01:39.50
As I mentioned before, everything is pretty much stock on router/switch settings. If you have any tips that allow me to identify the cause, I would appreciate the input. What puzzles me is the speed drop and quick memory usage increase. It occurs 7-10 seconds after the transfers begins. It looks like the data transfer hangs for a very short period of time (less than half of second) and the transfer speed decreases from 110-115MB/sec to 50-60MB/sec. The transfer is completed at this speed. No matter how many other files I try to transfer after, the speed won't go higher than 60MB/sec. If I reboot the router, I get the same cycle.

Link between HCM Processes Forms with portal

Hello Friend's,
Can anyone tell me how to link HCM processes application with portal. I created process in backend. tell me how to call that process in my portal.

Hi Ramesh,
i am not sure you got the process in Portal or not, but this steps helps you to get process in portal.
Go to SPRO --> Personal Management - HR Administrative Services - Configuration Process for HCm Processes and Forms - Process Configuration -- Setup Processes -- Validity for Processes -- Select Specify Valid Processes for start Application -- now it will prompt with Role of Initiator slect Manager/Employee/HR admin specfic start and end date
and still we have one more step to do...
hope it helps pls let me know if you face any problems in setting up HCM forms and processes i will try to help you out.

Help! Integrating high quality images and video.

I'm trying to create a relatively short slideshow with high resolution images (~3MB) and a couple of short video clips.
iMovie 6.0.3 ruins my pictures. They're blurry and pixelated. Is there a new version of iMovie that can help me import high quality pictures?
I don't need to create a DVD per se. I could just hook up my computer to a TV screen or use my laptop screen for presentation purposes.
What should I do?
Any help would be appreciated!

avoid using iMovieHD6, which is mainly meant to deliver content to TV = low res, low color profile, low framerate, interlacing..
use any specialized tool as PhotoMagico or Photo2movie..
you can slightly improve slideshow's quality, by setting up a HiDef project (720p/1080i), export as h264 and set the QTplayer app to 'high' ..
aside: the Preview in iM shows a reduced quality of projects .. never judge pic quality of iM on a computer..
and, don't hesitate to make use of the forum's Search feature.. we have approx. 5000 threads concerning pic quality..

RAC Issue with high Transaction OLTP + GC's

In the Lab i am testing in-house application with Oracle 10g.
Setup
- 2 Database servers (RHEL OS 3, IBM H/W, 4GB RAM)
- 2 in house Application servers (RHEL OS 3, IBM H/W, 4GB RAM)
- IBM Disk Array with 2Gbps fiber Cable Speed
- Cisco LAN Switch with 100mbps/sec Port
Application Detail-
-- Its a OLTP application.
-- Doing lots of insertion,update,delete,commit for each transaction.
-- With high application load,its doing 5000 DB tranactions/sec with database.
The following test scenario need to test
1. Start one application server and conenct with DB instance1 and push high load..
2. Start both application server and connect with DB Instance1b and push high load from both applications.
3. Start Both application server and connect with both DB servers ( For Ex.
(A1-DB1 & A2-DB2) and check the application compatibility with RAC environment ( Note- Here need to push very less db transaction data to DB servers).
4. Similar like 3 but with very high db transaction rate
Now these are the results
1. Full Success
2. Full Success
3. Full Success
4. Fail
Detail description of Case4 Failure.
When ever i am starting applications with high load, within few minutes application quesues are getting full and db instances are not able to handle load.
When i checked the Oracle ASH Report and then found following major events
1. gc buffer busy
2. gc current block busy
3. gc current multi block request
4. gc cr block 2-way
i checked the oracle documents and found three are major root cause for this issue.
-- Interconnect
-- Load issues
-- SQL Execution against a Large shared working set
But i am not sure, how i can come out from this issue.
If any one faced this issue with Oracle RAC. Please share your experience or give some suggestion to come out from this issue.

Hi,
you can use fiber for interconnect, Once i have looked for this option but haven't implemented.......
in this case your global cache requests are too much. one thing more if is it possible then divide the load according to domains. like same queries on on node and other domain queries on second nodes...... e.g. reporting on node2 and oltp transations on node1.
and kindly look into it...

Firefox becomes really slow then eventually unresponsive when loading a page with many hires images. Unsual high memory usage up to 2gigs just for firefox. Was never a problem with v3.6.

When loading a page with many hires images, Firefox becomes really slow and scrolling becomes jumpy then eventually becomes completely unresponsive. Unusual high memory usage of up to 2gigs just for firefox when loading these pages. This was never a problem with v3.6.

I encountered the same type of problem. Firefox running terribly slowly and slowing down my entire machine (Core i5 with 256GB SSD). Searching the forums, I found a couple of things about troubleshooting performance issues, one of which was to use '''hardware acceleration''', that is on by default. It was turned on on my PC, '''so I tried deactivating it, and it worked!'''
So doing the exact opposite as Mozilla support said solved the problem. It is really a pain now to work with Firefox. I'm using it because I have no choice, but I'd recommend IE and Chrome over Firefox... Whatever, the market will decide once Firefox has become to crappy...
