Many JS files
Have the developers thought about trying to consolodate the javascript code? I am looking at the html code for a tabbed panel with a fade effect and it loads nine javascript files. That is a lot of http requests for just one widget.
<script type='text/javascript' src='Spry-UI-1.7/includes/SpryDOMUtils.js'></script>
<script type='text/javascript' src='Spry-UI-1.7/includes/SpryDOMEffects.js'></script>
<script type='text/javascript' src='Spry-UI-1.7/includes/SpryWidget.js'></script>
<script type='text/javascript' src='Spry-UI-1.7/includes/SpryPanelSet.js'></script>
<script type='text/javascript' src='Spry-UI-1.7/includes/SpryPanelSelector.js'></script>
<script type='text/javascript' src='Spry-UI-1.7/includes/SpryFadingPanels.js'></script>
<script type='text/javascript' src='Spry-UI-1.7/includes/SpryTabbedPanels2.js'></script>
<script type='text/javascript' src='Spry-UI-1.7/includes/plugins/TabbedPanels2/SpryFadingPanelsPlugin.js'></script>
<script type='text/javascript' src='Spry-UI-1.7/includes/plugins/TabbedPanels2/SpryTabbedPanelsKeyNavigationPlugin.js'>< /script>
For Spry 1.0 widgets, each widget had one core file. Each of them had common things like addClassName(), removeClassname(), along with a bunch of basic functionality. So that adds up to a lot of redundant code.
This way, all that common stuff is kept in a single file. That means that each widget base class just has what it needs to glue everything together.
Many widgets are 'panel' based: accordions, tabbed panels, slideshows. So handling those panels is done via the PanelSet and PanelSelector files.
You will find SpryTabbedPanels2.js much smaller than the first version.
By components, for instance: SpryFadingPanels.js is only needed if you want to fade between panels. If you don't want that effect, you don't need to use it. WIth components and plugins, you or anyone else can write a different transition and make that available to all your Spry UI widgets.
I don't like all the includes either but it's the right way to go with what we are doing.
Thanks,
Don

what is the cause?
thank you
APsorry i can explain well the issue
for our experience
LDAP access causes the opening a lot of file descriptor?
The LDAP proves ist still running and is still opening files. Meanwhile, because of the SSL communication with application, some files are Created in the CACERTS directory
Suddenly, the OS has reached its file descriptor limit: an error message �Too many open files� appears
Question: the situation is : that files cannot be closed in the CACERT director, because the OS has not more file descriptors (because the ldap process has used all file descriptors to the limit)?
is related on LDAP this problem?
thank you for your kindness guys!

Java.io.IOException: Too many open files while deploying in soa 11g
hi all,
I am getting a strange error while deploying any composite .. it's a hello world kinda composite but while i am trying to deploy it i am getting "java.io.IOException: Too many open files" while deployment.. i have tried to deploy it in 2-3 ways but all of them resulted in the same error..bouncing the soa server might be an option but can someone give an insight as why it is happening and can it be resolved without restarting the server..
Thanksyes..so this problem is with unix only ..coz i previously worked in Windows ..never got this problem..

Very slow Backup (Many little file in many subdirectories)
- I have a Netware 6.5 SP8 server with the post SP8 NSS patch installed (NSS version 3.27.01 April 7, 2009)
- iSCSI Initiator Version 1.06.05 October 30, 2008 connecting a 410 GB NSS Volume (Lefthand Networks iSCSI SAN)
- the volume contains user data, and contains, from the Root, a USERDATA directory, which then contains 32,749 individual user directories.
- The majority (90%) of the user directories are empty
- each user directory has it's own trustee assignment, and space restrictions
- compression is enabled
- 376,269 Files using 45,556,460,661 bytes in 221,439 directories so the average would be around 121K per file and as you can see it's very Directory intensive
TSATEST, indicates approximately 850 MB/min result, but when I attempt to back up the data using my backup software (NetVault, which uses NDMP), the performance is hideous. A Full Backup runs around 135k/sec or 8 MB/min (try getting that done in any size backup window) . I have also tried other backup solutions, with the same basic result.
I assume the issue is with indexing, but I'm not sure what to check at this point. I've been trying every suggestion I could find. I've gotten the throughput up to about 1.5M/s, but obviously need better. Just wanted to know if anyone here had any suggestions that might help me to make this function more efficiently, or any TID's that have proven helpful.

I have seen this in Java development shops with millions of 1kb files
and folders. The nature of Java.
- Use tar or zip on the local server,not across the wire to compress
those types of data folders.
- Exclude those folders from backup
- Then backup only the zip or tar files.
or maybe look into rsync as I think is copies by hardware blocks not
files?????
- maybe need toreview your environment if it is a development shop like
Java.Maybe switch to GPFS or Reiser for many small files if you can, EXT
could handle it for your small amount of data though. -
How to merge many XML files into one?
Hi: I got a small project to combine many XML files into one and convert the combined XML file in Excel using AppleScript. My XML files look like this:
<?xml version="1.0" encoding="UTF-8"?>
<Metadataobject>
<from>[email protected]</from>
<jobname>B3_IM09MBDUF</jobname>
<pages>2</pages>
<priority>3</priority>
<timezone>CEST</timezone>
<year>2013</year>
<month>7</month>
<day>15</day>
<hour>11</hour>
</Metadataobject>
and like this...
<?xml version="1.0" encoding="UTF-8"?>
<Metadataobject>
<from>[email protected]</from>
<jobname>P1_FR1330G006007_Kate_van der Vaart</jobname>
<pages>2</pages>
<priority>1</priority>
<timezone>CEST</timezone>
<year>2013</year>
<month>7</month>
<day>12</day>
<hour>16</hour>
</Metadataobject>
I get many XML files like this. And I want them to be combined and shown like this:
<?xml version="1.0" encoding="UTF-8"?>
<Metadataobject>
<job id="1">
<from>[email protected]</from>
<jobname>B3_IM09MBDUF</jobname>
<pages>2</pages>

</Metadataobject>
And finally the combined XML file converts in Excel sheet with column headings "Job ID", "From", "Job Name" and so on...
Or there is another best way to get the same result...
ThanksThat is just an intermediary state to get to the excel version. Actually I get many small XML files (as shown above) from client and I want them all combined in an excel sheet with common column headings... like this...

Thanks for your response. -
I recently deleted many duplicate files. In the midst of it my Itunes songs are not in Itunes. They are in two different folders. One under 'Music' in my ID. And two under a MyMusic file in Documents. How do I know which one to import?
Thanks, this is not an ideal answer but probably the most sensible one in my case.
I will try it unless someone has a better suggestion, but I'll wait a bit as it will take me a few days anyway (I had actually tried to create a new smaller playlist or download by album, but at this stage the music app is not letting me queue a list of songs for download - I think I will have to disable and re-enable iTunes match which will probably delete all the songs).
I have to say I am not very impressed with Apple here - having an online backup of all your data and beeing able to restore it to a new device easily was a strong selling point of iCloud. For music, they are Definitly not delivering at the stage. -
Converting many numbers files to PDFs?
Hi everyone!
I would like to convert many Numbers files to PDF documents. Every Numbers document should be a new PDF with the same name!
I even tried to write a workflow file with Automator, but I dont get the "create a PDF"-part running.
Furthermore I googled for 2 hours, but all scripts I found do not work with the latest Numbers version...
Please help me... Maybe one of you have a Apple Script or a solution using Automator?
OS X 10.9.3
Numbers Version 3.2 (1861)Dear Lori,
promptUser =false, see below.
Does not work.
All programs that might disturbe PDF output removed from computer.
Does not work.
I am now investing some evenings into Word-VBA, making a script loop through the subdirectories over several levels (does Acrobat do that anyway?)...
Does not work.
Not yet.
It will have to...
best regards,
Boris

But this problem is understandable, as the database is not running. The main problem why database is not running, I have found the reason but do not understand how to solve the problem.
Since, the database was not running, I tried to startup the database, I then came across the following which is my problem (Why so many files are open? Linux OS error says too many files open. See below,

Can anybody has run into such problem and guide me to a solution, please?
ThanksHi,
yes, this DB was functioning o.k. this configuration script was part of RMAN daily backup.
Last night the backup failed. So, when I opened "Failed job" in the EM, I saw this type of messages.
That was the starting point. Gradually, I tried to narrow down on to the actual problem and found the findings as I have posted.
One way of sovling problem, I thought that, all these processes I would kill and then try to open the database, it might startup. However, that wouldnot lead me in ensuring this won't occur again.
That's why I am trying to understand why it should open, so many processes (why spawn so many .flb files?) Any thoughts you have around this?
I will try to restart the OS as the last resort.
Thanks for your help and suggestions.

"java.io.IOException: Too many open files" in LinuX
Hi Developers,
* I am continiously running and processing more than 2000 XML files by using SAX and DOM.....
* My process is as follows,
- Converting the XML file as Document object by DOM....
- And that DOM will be used while creating log file report, that log file will be created after executing all XML files..
* After processing approx 1000 files, it throws *"java.io.IOException: Too many open files" in LinuX system* ....
* I have googled more and more in all sites including sun forum also, but they are telling only to increase the system config by ULIMIT in linux....If i increase that its executing well without exception........
* My question is, Is it possible to do it by JAVA code itself or any other VM arguments like -Xms512m and -Xmx512m.....
* Please let me know , if you have any idea.....
Thanks And Regards,

WLS 10.3.5 on RHEL 5.4, SocketException: Too many open files
Hi
I'm running Weblogic server 10.3.5 on Red Hat Enterprise Linux Server release 5.4 (Tikanga), with Java jdk1.6.0_27.
My order handling application, when receiving client orders, needs to make outbound SOAP calls to fulfill the order. During a performance test, we got following errors:
####<Feb 10, 2012 2:28:41 PM ICT> <Critical> <Server> <KKMOMAPP2> <KKMOMPE2> <DynamicListenThread[Default]> <<WLS Kernel>> <> <> <1328858921806> <BEA-002616> <Failed to listen on channel "Default" on 172.24.106.81:4095, failure count: 1, failing for 0 seconds, java.net.SocketException: Too many open files>
I monitored the java process of this application, when the "Too many open files" error happened, it had 1388 open file descriptors, among which 655 were sockets.
I also monitored the total open file descriptors of the weblogic user account, the count was around 6300 during this error.
These numbers are far smaller than the file limits configured on OS:
- Under weblogic account, ulimit -n shows 65536
- /proc/sys/fs/file-max shows 772591
- Following lines are already in /etc/security/limits.conf
weblogic soft nofile 65536
weblogic hard nofile 65536
weblogic soft nproc 16384
weblogic hard nproc 16384
I did another test using a simple java program to open large number of sockets under weblogic account. It has no problem to open 15,000 sockets. It seems the file descriptor limit is indeed quite high, but for some reasons, the Weblogic process fails even when it has merely 1388 open files. Are there other Linux or Weblogic parameters I should tune? Or anything else I missed?
Thank you very much
NingHi All,
Any help on this issue ?

Java.util.zip.ZipException: Too many open files on Linux
Hi,
We have web application running on Caucho's resin server on jdk 1.5.0_11 and Red hat Linux. We are noticing that java process is running out of file handles within 24-30 hours. We have file limit of 5000 which it consumes in 24 hours throwing 'java.util.zip.ZipException: Too many open files'.
I have made sure all sorts of file handles are closed from application point of view. Here is the snapshot of lsof (list of file handles) from java process. The following list keeps growing until it runs out of limit. Do you have tips/suggestions on how to mitigate this problem (considering we dont want to increase ulimit for this process)? Also, can you make out any thing more from the description of file handles like, are they unclosed POP3 connections or URL connection to external sites?

It was oracle driver which had some compatibility issue, we upgraded our Oracle client driver to newer version, and this fixed the problem. Base line, there was nothing wrong with application code, code was doing good resource clean up, but oracle driver was leaking handles per every connection.

Runtime.exec - Too Many Open Files
System version : Red Hat Enterprise Linux 2.4.21-47.ELsmp AS release 3 (Taroon Update 8)
JRE version : 1.6.0-b105
Important : the commands described below are launched from a Web application : Apache Tomcat 6.0.10
Hello,
I'm facing a problem already known, but appearantly never really solved ??!! ;)
When I invoke many system commands with the 'Runtime.exec(...)' method, there are open files that are not released (I can see them with the "lsof" system command) .
At the end, the unavoidable "too many open files" Exception.
The lauched commands are "ssh ... " commands.
In the topics relating to this problem, the solution is always to close all Streams / threads and to explicitely invoke the method "Process.destroy()".
My problem is that this is what I do ! And I can't do more...
Here is the code :
Runtime rt = Runtime.getRuntime();
Process process = rt.exec("ssh ...");
// ProcessStreamHolder extends Thread and reads from the InputStream given in constructor...
ProcessStreamHolder errorStream = new ProcessStreamHolder(process.getErrorStream());
ProcessStreamHolder outputStream = new ProcessStreamHolder(process.getInputStream());
errorStream.start();
outputStream.start();
exitValue = process.waitFor();
try {
errorStream.interrupt();
} catch (RuntimeException e) {
logger.warn("...");
try {
outputStream.interrupt();
} catch (RuntimeException e) {
logger.warn("...");
try {
process.getInputStream().close();
} catch (RuntimeException e) {
logger.warn("...");
try {
process.getOutputStream().close();
} catch (RuntimeException e) {
logger.warn("...");
try {
process.getErrorStream().close();
} catch (RuntimeException e) {
logger.warn("...");
process.destroy();Does someone know if my code is wrong or if there's a workaround for me ?
Thanks by advance !
Richard.Don't interrupt those threads. Close the output stream first, then wait for the process to exit, then both threads reading the stdout and stderr of the process should get EOFs, so they should exit naturally, and incidentally close the streams themselves.

"Too many open files" Exception on "tapestry-framework-4.1.1.jar"
When a browser attempts accessing to my webwork, the server opens a certain number of file descriptors to "tapestry-framework-4.1.1.jar" file and don't release them for a while.
Below is the output from "lsof | grep tapestry":
java 26735 root mem REG 253,0 62415 2425040 /usr/local/apache-tomcat-5.5.20/my_webwork/WEB-INF/lib/tapestry-portlet-4.1.1.jar

These unknown references are sometimes released automatically, but sometimes not.
And I get "Too many open files" exception after using my application for a few hours.
The number of the unknown references increases as I access to my webwork or just hit on "F5" key on my browser to reload it.
I tried different types of browsers to see if I could see any differences in consequence, and in fact it differed by the browser I used.
When viewed by Internet Explorer it increased by 3 for every access.
On the other hand it increased by 7 for each attempt when accessed by FireFox.
I have already tried optimizing the max number of file discriptors, and it solved the "Too many open files" exception.
But stil I'm wondering who actually is opening "tapestry-framework-4.1.1.jar" this many.
Could anyone figure out what is going on?
Thanks in advance.
The following is my environmental version info:
- Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
- Java: 1.5.0_11
- Tomcat: 5.5.20
- Tapestry: 4.1.1Hi,
Cause might The server got an exception while trying to accept client connections. It will try to backoff to aid recovery.
The OS limit for the number of open file descriptor (FD limit) needs to be increased. Tune OS parameters that might help the server to accept more client connections (e.g. TCP accept back log).

Why Are Many iPhoto Files Now Thumbnails?
Greetings All: I've searched the forums for answers to my question, and there is a partially useful solution which dates back to 2006 about shrinking photos in iPhoto. All one needed to do to get around this problem was to go to ~Library/Pictures and make sure that iPhoto Data wasn't the selected folder for iPhoto. The solution was to select iPhoto Library as the source for iPhoto.
Now, things are a bit more complex. I cannot find a Pictures folder in ~Libary directory. It's now moved to ~Pictures. I have only one iPhoto libary file and it's called "Rebuilt Library". When I'm in Events mode and browsing iPhoto, I can get the app to show me the individual files, but I don't know where to find them. Often there are six copies of any given file with (EDIT) appended to one of the copies. As I click on each one, it's apparent that they are all tumbnails. Some of the photos are orignial size, but many aren't.
I wonder if I am doing something wrong, selecting an improper libary, or if I can kiss 800 or so of my Africa photos "goodbye"?
Thanks in Advance.
-jpkmdLN:
I use iPhoto '11 v9.3. I own a MBP i7 dual core running OS 10.4.7. How did I get to the individual photo files? By selecting an indivdual photo, going to the "Edit" menu on iPhoto, and dropping down to the "Reveal in Finder" command. I saw folders marked by date full of individual photo files. I clicked on several of them which seemed to be duplicates named in series; for example:
IMO2345.JPG
IMO2345.1.JPG...
IMO2345.6.JPG
All seven photos were identical and all were of thumbnail size.
Also present were photo files marked with (EDIT) such as
HOLIDAY2005.JPG
HOLIDAY2005(EDIT).JPG
Again, both photos identical and both in thumbnail size.
I opened these photos with Lemke's GraphicConverter. You say this is an SQL database and cannot be interpreted by any other application but iPhoto. (I had to look up the definition of SQL.) From my non-tech point of view, I was struck by the fact that there was so much duplication, so many (EDIT) files, and all in thumbnail size which is how they appear in iPhoto. I didn't delete or rearrange any of the files. I won't monkey around with that database again.
There are two iPhoto libraries in my ~Pictures folder. One is iPhoto Library which is blank. The other is Rebuilt Library which contains all the data; it was created at the suggestion of the iPhoto application I was running in about 2006-2007. I don't recall exactly how I accomplished this.
There are still some photos which are at normal size. I recall going through the approximately 4,500 photos in my iPhoto collection (there have to be copies in here) and taking out thumbnail duplicate photos. I took a photo journey to Africa a few years ago, and some of those photos seem to be thumbnail now, which makes me panic; however most of the other photos I have in iPhoto are thumbnail size now. I don't know how to proceed from here. At the time I did it, looking at the individual photos in the folders seemed like a reasonable thing to do. I'm a doctor, and I felt like doing some exploratory surgery. But I won't do that again. -

I recently purchased Wondershare software. I've converted many video files and made a movie. imovie quitting. Wondering if there is a problem with Wondershare and imac compatibility. Any thoughts?
RickNot sure about the codec- Wondershare asked where I was sending to in setup and I selected imovie. It did the rest. I have been successful with editing on storyboard, but imovie (09) quits when I attempt to view project full screen, or prepare the movie for sharing. I have removed some files (to ensure headroom), and have installed most recent updates.
