Too many javas?

Hi,
Lately I've been having some minor problems with websites. I was told
that the problems are Java related.
I checked in Add\Remove Programs and there's 4 listings:
1) J2SE Runtime Environment 5.0 update 2 ? 125MB
2) J2SE Runtime Environment 5.0 update 9 ? 119MB
3) Java 2 Runtime Environment, SE v1.4.1_02 ? 1.72MB
4) Java Webstart ? 46.13MB
Plus, when I did a search of my C: drive, there are 39 listings
everywhere from Doc's & Settings\Adm to WinSys32, for .java and Java.
Also, in C:\Windows\Downloaded Program files, there's 2 listings for
Java Runtime Environment 1.4.1_02, both listings say "installed".
Could having 2 listings in Downloaded Program Files be causing the
problems?
Or, should I go to Add\Remove Programs, uninstall all the Java stuff, and start fresh? What about the registry, also? I've no qualms about editing the registry.
If uninstall is your recommendation, other than what I mentioned above,
is there a better way to uninstall? If so, where and how? I'm "fairly"
competent with computing, but I don't want to do something wrong.
Also, would it be possible to send me a link to download the
latest\newest Sun Java for the "home user"? I do not have Microsoft
Java on my system.
My OS: Win XP Pro, SP1, with all patches and hotfixes installed and
twice the memory I'll ever need.
Thank you for your time, I appreciate it.
Sincerely,
jpChris

Just remove everything except for the latest JRE version (so 5.02 and 1.4.1) and Webstart using the System Panel. Won't solve any problem but at least releases some space.
Also, would it be possible to send me a link to
download the latest\newest Sun Java for the "home
user"? Look up. See the item called "Downloads". Get the J2SE 6.0 JRE. Scrap all others if you want to upgrade to that.

Too many java processes.

Hi,
I have installed Forms & Reports Services Standalone 10.1.2.0.2 on RHEL 5 and applied the 10.1.2.3 patch to it. After the patch, the java processes continue to grow so fast that sometimes when I open a new session and try to switch to oracle user, I get a "too many processes" error.
Apparently these java processes are from the Reports Server, however I haven't even yet configured the Reports server and am not doing anything with the reports server at the moment. Right now, I'm only configuring the Forms server.
So, I am wondering what is going on here - why are there so many java processes and what to do about it?
Thanks.

Hi,
Based on dependency better you can go for 3 parellel process at a time as what we are doing in our project.
check schedule time for each your process chain which fetchs data from source system (Info Package) and re schedule them which should not execute at a time (make it max 3) and try again

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..

"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,
JavaImran

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?

Finally we resolved this issue. 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.

Java.io.FileNotFoundException (Too many file open)

Hi,
I have an application wherein I have to open an XMl file, make amends to it and then write it back. It is possible that the same XML file be opened more than once. After processing lots of XMl files I get the following error:

}Here also I am not explicitely opening any handle. parse method should close the file after creating a DOM tree.
I would appreciate if someone could give me some directions as to what might be wrong.

I'm finding that builder.parse(File) doesn't close the file. I now create a FileInputStream from the File and make sure I close it myself in a finally{} block.

Too many session in the AS java server node?

I have install a Netweaver JAVA portal system for customer , this is cluster system one CI and 10 DIs, I found there are too many active session in each server node , I konw , the user can login anyone instance through the web dispatcher , but I found nearly 3000 active session in each server node after a work day in average, and there are too many iterative session , sometime one user can have 30-40 session in each server node after a work day .
I think the memmory is critical if there are have too many session , and sometimes, the log off fution of portal can't work ,so I decided to set a time-out parameter of the session (4 hours),but this is active method to delete the session of the user ,no matter the user is working with system .
Who can tell me how to effective control and enhance user's session managment of Netweaver Java server .

Check note 873190 or 376915

Java - too many levels of symbolic links

Hi everyone,
Today I've tried to launch eclipse and I noticed this strange error :
[^81%][11:12][cafe][~]$ eclipse
/usr/bin/java: line 2: /usr/lib/jvm/default/bin/java: Too many levels of symbolic links
/usr/bin/java: line 2: exec: /usr/lib/jvm/default/bin/java: cannot execute: Too many levels of symbolic links
Inspecting the /usr/lib/jvm folder revealed the issue:
[^82%][11:14][cafe][~]$ cd /usr/lib/jvm
[^82%][11:15][cafe][jvm]$ ls -lhA
total 4.0K
lrwxrwxrwx 1 root root 7 Sep 5 11:12 default -> default
lrwxrwxrwx 1 root root 11 Sep 4 16:44 default-runtime -> default/jre
drwxr-xr-x 3 root root 4.0K Jul 3 16:02 java-7-openjdk
lrwxrwxrwx 1 root root 7 Sep 4 16:44 java-default-runtime -> default
So I've just removed the default symbolic link and replaced with :
[^82%][11:15][cafe][jvm]$ sudo rm default
[^84%][11:16][cafe][jvm]$ sudo ln -s java-7-openjdk/jre default
[^84%][11:17][cafe][jvm]$ ls -lhA
total 4.0K
lrwxrwxrwx 1 root root 18 Sep 5 11:17 default -> java-7-openjdk/jre
lrwxrwxrwx 1 root root 11 Sep 4 16:44 default-runtime -> default/jre
drwxr-xr-x 3 root root 4.0K Jul 3 16:02 java-7-openjdk
lrwxrwxrwx 1 root root 7 Sep 4 16:44 java-default-runtime -> default
and now eclipse launches without any issues.
So I ask, is this the correct behavior? and..
Why do we have so many symbolic links in this folder?
Cheers,

Acme GiFEncoder: java.io.IOException: too many colors for a GIF

I have been using the Acme GifEncoder to save images as gifs. I have been using this quite successfully until today. For some reason it now gives an error when I try to use this in some circumstances. The exception is:
java.io.IOException: too many colors for a GIF
I am not sure why it will work in some situations and not others. If anyone can give any insight on this problem then I would appreciate it.
Thanks

Thanks for the reference to the quantizer. I will try it out and see if it works.
That is going to lead me on to have a bit of a rant about GifEncoders. I realise that gifs are limited to 256 colours. It is ridiculous that a GifEncoder would not limit the number of colours for you. If you have an image in another format such as jpg that does not have a limit the number of colours, the encoder is not able to convert it into gifs unless it has the number of colours reduced. As far as can tell this should be an essential function of the encoder, unless anyone can tell me differently.
Also if anyone can advise me on the Acme JpegEncoder I would appreciate it. It does not seem to work in any shape or form. I am not trying to do anything in particular with it now, so I have no code to show. I did try to use it before and it did not seem to work, so if anyone knows how to get it to work that would be great.
Once again, thanks for your help.

Getting java.io.FileNotFoundException: Too many open files

I have search for different strings in a file again and again. I am using following code:
try
               fileReaderObject = new BufferedReader(new FileReader(fileObject));
               String inputLine;
               while ((inputLine = fileReaderObject.readLine()) != null)
                    if (zipCode.equalsIgnoreCase(inputLine.split("\t")[0]))
                         s = inputLine;
                         fileReaderObject.close();
                         return s;
               fileReaderObject.close();
          catch (Exception e)
               Utils.writeMessage(e.toString());
               e.printStackTrace();
          }But getting java.io.FileNotFoundException:file/emp_info (Too many open files)
1. Whats the main reason of this exception and how can it be removed.
2. Is there any way to move the pointer to the start of the file. I tried reset() but its seems to have some problem.
-vc

A hint: your fileReaderObject is not closed if an exception occurs.
Lacking desctructors, the Java-ish way is to close in a finally clause.

Getting java.io.IOException: Too many open files+ClassNotFoundException

Dear All
We have a web application deployed on Rational Application Developer 6.0 (Operating System is Windows 2000 professional) our users are randomly getting java.io.IOException: Too many open files+ClassNotFoundException when they click on some servlet or jsp link, but they are getting this error randomly for example when they click some link they may get these exceptions but refreshing page or clicking once again on same link executes servlet successfully.If anyone could help on this topic we will be grateful

Java.io.IOException: Too many open files

I am running web-service, by which i have to run .sh file on linux. My code is as follow,
import java.io.BufferedReader;

you are opening the above file and not closing,,
so that each and every file still in existence, one the memory full, then you are getting this error..
please to confirm on this..

If it could help you, the splash screen is display a short time and the progression bar is beginning but for a short time only, after what the process is dying.

You have exceeded your max open files limit as determined by your operating system. You need to talk to your system administrators.
