Performance Pack problem under win2k

i am running wls 5.1sp5 under win2k.
and get always the same errormessage at startup:
<Posix Performance Pack> Could not initialize POSIX Performance Pack.
<Performance Packnc> Unable to load performance pack using java I/O
what am i doing wrong ??

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

Problems with the performance pack for Linux.

Hi,
I have just installed sp9 for WL 5.1 and with it the performance pack. But I
get many of these exceptions:
Wed Jun 06 15:46:09 EDT 2001:<E> <HTTP> Connection failure
java.net.SocketException: Error in poll for fd: '30', revents: '23'

at weblogic.socket.SocketReaderRequest.execute(SocketReaderRequest.java:23)
at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:129)
Everything seems to be fine on the site, but that exception does not look good.
Anybody knows anything about this? Thanks,

Hi all,
I'm looking for a way to determine the total number of sessions per day or

[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..

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.

URGENT - WL server crash in production - Native performance pack ??

Hi,
We are experiencing periodic crashes in our production environment of the
nature where WLS just stops running and exits out, i.e. the JVM exits
abruptly. Many times we have seen http tunneling / socket related exception
just before the crash occurs.
Following is our configuration -
WL 4.5.1 service pack 13
JDK 1.1.7B
OS: Windows NT 4.0, sp 5
Oracle 8.1.5 with Oracle Thin drivers for JDK 1.1.7
Native IO : true i.e we are using the NT performance pack.
The latest exception that we have seen is as under -
Wed Jan 24 11:01:46 EST 2001:<E> <HTTP> Servlet request terminiated with
RuntimeException:
Wed Jan 24 11:01:46 EST 2001:<E> <HTTP> java.lang.NullPointerException
at weblogic.socket.TunnelContext.getServlet(Compiled Code)
at weblogic.socket.MuxableSocketHTTP.invokeServlet(Compiled Code)
at weblogic.socket.MuxableSocketHTTP.execute(Compiled Code)
at weblogic.t3.srvr.ExecuteThread.run(Compiled Code)
This seems to be a problem related to the use of performance pack and native
sockets during HTTP tunneling. In the latest crash, we got the exception
pasted above and the server crashed about 2 seconds after that. We have seen
things in the recent past where we get a HTTP tunneling related exception
and the server exits immediately afterwards.
Is anybody using the native performance packs in their production
environment on the above mentioned configuration? Has anybody seen this kind
of behaviour? Does anybody have any input on the use of native performance
pack (nativeIO) and its pitfalls in WLS 4.5.1 and sp 13 or otherwise?
Some research and investigation from our side has revealed the following
(hope it helps, but want to know more and for sure) -
In the weblogic.socket.NTSocketMuxer.java, there is an infinite loop that
tries to send HTTP tunnel keep alive messages to the clients. There it tries
to get the TunnelServlet to send the message. It gets a runtime exception
(the one in the trace above) but that is caught and the loop goes on. But on
the next pass through (in about 2 secs. or so), it makes a some native calls
(getNextSocket(), deleteIoStructure() and memcpy() which are all native
methods). Experience says that all native calls are prone to serious
problems.
So, does anybody have any info./solution/suggestion to shed some light on
this issue. This is an urgent issue as it is affection the production
environment.
Thanks in advance.
-SG

No, this is not currently available. FWIW, native io only helps when you
have a lot of sockets.

Audio transmit problem under redhat linux 9

Hi !!
I have already compiled J2sdk1.4.2 and JMF2.1.1e performance pack for linux and they both work alright under Redhat linux 9. JMStudio works fine to playback audio files. The problem I'm having is when I try to transmit and receive audio files through AVTransmit2, AVReceive2 and JMStudio!! They just don't work!!
AVTransmit2 and JMStudio just starts to transmit but on the receiving end both jmstudio and avreceiver2 just waits for rtp data but none arrives!!
Can anyone help me with this problem?? I've already tried spending a whole day cranking my brain about this!!
Thanks in advance

make sure your hostname is somehostname.com , and make sure you have your IP mapped to your hostname in /etc/hosts file.

Unable to load performance pack, using Java I/O on WL60, sp2

Dear Deyan,
Thanks for your help. We do have $WEBLOGIC_HOME/lib/solaris in LD_LIBRARY_PATH,
which is set when running ". setEnv.sh" before startWebLogic.sh.
We failed on one patch: 105210-27, for some reason.
The strange thing is: in the same machine, all WL60 instances running under user
accounts (under /users/developers/) have no such error. But it happens under some
account, like accounts under /export/home/, etc. /user/developers is mounted on
another physical machine.

You should have the $WEBLOGIC_HOME/lib/solaris directory in your LD_LIBRARY_PATH
so that
the server can load the performance pack (which is a shared library called
libmuxer.so).
If it is present then do a ldd libmuzer.so and you will see if any libraries
that it
depends on are missing.
Also make sure you have all of the requered patches for 2.6 installed.

Native performance pack

Does the native performance pack work ok with weblogic 4.0.3 and
JDK1.1.7?
I looked at the 4.0 release notes and under 4.0.2 it seems there was a
problem. Is this fixed in 4.0.3?
Thanks

It's been tested and does work under 4.0.3. and above.

Http problems under load

Running WL 51 w. SP3, Solaris 2.7, java 1.2.1, and using loadrunner to
simulate 160 users doing http GETs directly to the weblogic http server
(port 8001). There are a number of errors showing up in the weblogic
log that I don't understand.
First, I get a few of:
Tue Aug 08 18:13:45 GMT+00:00 2000:<E> <HTTP> Servlet request terminated

There are 4 client machines each running 40 clients, and these errors
seem to only affect one of the client machines.
If I run the test just using that machine, it runs fine - it only seems
to show up under load.
I don't know if it's a coincidence or not, but the numbers seem too
regular - I get (in order):
1480 Connection rejected: messages
40 <Posix Performance Pack> Failure in processSockets()
40 Connection rejected: messages
80 <Posix Performance Pack> Failure in processSockets()
240 Connection rejected: messages

Thoughts? Solutions?

HTTP-form. And of course
I got the same exception, because I forgot to set the correct
Content-length in the CLIENT SIDE.
My first HTTP-header looks like this:
POST /pqr HTTP/1.0<CRLF>
Content-type: application/x-www-form-urlencoded<CRLF>
Content-length: 17<CRLF><CRLF>
xml=<blabla></blabla>
And it was really bad: I counted only the xml-like string, instead of
the full data (incl. "xml=")
When I corrected it was goood!
So, I think the source of Your problem isn't in the WS-side: try to
check your client...
And Your client can't close the connection before sending all data!!!

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.

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.

Performance Pack Unable to load - WLS6.1 on RH7.3

When booting WLS 6.1 SP3

What Michael means is that when the Performance Pack fails to load, the Java
version of the code will be used instead so that the server will continue to
function. If all you want to do is get rid of the error message, set the
following property in the weblogic.properties file:
weblogic.system.nativeIO.enable=false
If you are using Service Pack 8, your problem may be related to a known issue
with SP8 and certain platforms (HP-UX and AIX) not being able to load the
performance pack. Please contact technical support for more information.
Thanks,
Robert

Michael,
Thank you for your mail.
You can do without it. It isn't ported to Tru64.What do you mean "do without it"?
The platform support page for WebLogic Server is located at:
http://www.weblogic.com/platforms/index.html
If I read the document in the link, WLS5.1 would support Tru64. Doesn't it
support posix perfromance pack? I mean how can I remove the posix
performance error?
I am using WLS5.1 sp6 and 8 on Tru64 V5.0A. But the documentation says
WLS5.1 work with Tru64 V4.0F. Does it mean that performance pack will not
work in my environment?
Have you seen people who succeed in executing performance pack with the same
environment as mine?
