Could anybody explain this warning message regarding Posix Performance Pack

Hi,
I am getting following message on my console :

I have deployed the WL server on HP-UX 11.0 and wlserver version is 6.1 sp2. Could
anybody explain the warning message ?

This is a known issue.
Contact [email protected] and ask for "Combined muxer" patch.

Posix Performance Pack & file discriptor limitation

This question doesn't appear to relate to our Enterprise product, so I'm
responding to this message in the performance newsgroup as well. Please see
answers below:
Andy Ping wrote:
What is Posix Performance Pack about?This refers to the availability of enhanced I/O handling (enabled by default
with the Solaris version of WLS) and is documented at:
http://www.weblogic.com/docs51/admindocs/tuning.html#performance packs
>
And How to resolve the file dirscritor limitation? Is ulimit OK?The Solaris file descriptor limits are set using lines similar to:
set rlim_fd_cur = 1024
set rlim_fd_max = 8192
in your /etc/system file. In the above case, user processes are allowed 1K open
files by default and can up this limit to 8K files using the ulimit command.
You might have noticed that this command is used in the weblogic startup script
to accomplish this. Judging by your log entries, I'd guess that your tunables
are both set to 512. You might want to consider raising your maximum to 1K.
Perhaps other newsgroup readers can suggest/recommend better file descriptor
limits.

And I never installed the Performance Pack or something like that can you Help
me?
Thanx Alot!!

1. Set ld_library_path enviornment variable as per BEA docs.
2.You don't have to install Performance pack. You have Enabled Performance Packs
or by default performance pack are enabled on sun solaris.
Here is a step :
To use the Administration Console to make sure performance packs are enabled:
Start the WebLogic Server Console.
Open the Servers folder in the navigation tree.
Select your server (myserver in a default installation) in the Servers folder.
Select the Configuration tab.
Select the Tuning tab.
If the Native IO Enabled check box is not selected, select the check box.
Click Apply.
Restart your sever.
Thanks

This happens with WebLogic every time when Windows version changes:
in 1.3.1 system property "os.name" is "windows 2000" when running on XP, and
in 1.4 it is "windows XP". Since Windows names are hardcoded somewhere in
WebLogic,
and it doesn't know anything about Windows XP, it thinks that it is running
on Unix and
attempts to load Posix performance pack (as you can see in the exception
stacktrace).
You can fix this by adding -Dos.name="windows 2000" to the command line.

Tru64 Performance Pack - Unable to load performance pack...

Have a 2-processor Tru64 box with 1/2 Gig memory

Are you sure that the performance pack for your platform is available? I didn't see it listed on our platform support page. You might want to
check with customer support to determine if your platform does support the performance pack.

[BEA WEBLOGIC SERVER 5.1 sp8] performance pack load problem ....

Hi,
I am trying to use the weblogic server performance pack on BEA WEBLOGIC SERVER 5.1
sp8.
As explained in the following doc : http://www.weblogic.com/docs51/admindocs/tuning.html#performance%20packs
I use the following configuration :
weblogic.properties : weblogic.system.nativeIO.enable=true
LD_LIBRARY_PATH is set to "/bea/weblogic/wls510_sp8/lib/solaris"
Technical environement : SunOS 5.8 Generic_108528-06
But when I restart the server I have the following message :
"Mo Jun 03 18:19:06 CEST 2002:<A> <Posix Performance Pack> Could not initialize POSIX
Performance Pack.
Mo Jun 03 18:19:06 CEST 2002:<E> <Performance Pack> Unable to load performance pack,
using Java I/O."
Could you help me on this point, please ?

I think my Q is not clear. I shall explain how the application works. I am having application based on Swings and that is a website building program. User has options like ading an image into their site with an element called 'Image' available as part of the system. Then user can either select an image from the picture gallery provided or can upload his own image.
Now, if the user is uploading a picture that has space in name ( we use a servlet program to upload the image into user directory), it will get uploaded. But when the swing program tries to paint the image in the Image element ( It is essentially a JLabel ), the program is sending a request to the WL server. Since the URL contains space in name, server returns error. Even if do URL Encoding, it will add %20 in the URL and still WL will report error saying that file not found. It seems that WL is unable to process requests that has space in the URL.
If any one has any solution to this, please help..

And you are missing execute threads 1 through 25. Where did they go?
The only
threads you have left are the ones listening for requests - and they
don't do
any work. Find out what happened to the missing threads.

Yes, this is a known problem that we discovered recently.
Contact [email protected] or wait until next service pack goes out.

In most cases, these errors can be ignored. Please open a support case with BEA and
report this problem along with a description of any observed side effects (if any).

I guess it has something to do with the File Descriptor.I ahve the file descriptor
count set to Max(8096).
Does any one know what this means.

Problem when starting performance pack

Environment: AIX 4.3.3, JDK 1.2.2 with lastest fix, weblogic 5.1
When starting weblogic, the weblogic.log shows:
<POSIX Performance Pack> Could not initialize POSIX Performance PACK.
<Performance Pack> Unable to load performance pack, using JAVA I/O.
I have weblogic.system.nativeIO.enable=true set in the weblogic.properties file
and LIBPATH pointing to ~weblogic/lib/aix .
Appreciate if somebody here can give idea where to look into in order to load
the Performance Pack.
Thanks for any input

Could you do a directory listing of the directory that contains the
performance packs?

Environment: AIX 4.3.3, JDK 1.2.2 with lastest fix, weblogic 5.1
When starting weblogic, the weblogic.log shows:
<POSIX Performance Pack> Could not initialize POSIX Performance PACK.
<Performance Pack> Unable to load performance pack, using JAVA I/O.
I have weblogic.system.nativeIO.enable=true set in the weblogic.propertiesfile
and LIBPATH pointing to ~weblogic/lib/aix .
Appreciate if somebody here can give idea where to look into in order toload
the Performance Pack.
Thanks for any input

The perf pack is native code. It must be ported to each platform. Since
WLS only supports Solaris/SPARC, this port hasn't been done and that's why
the lib doesn't work.
