WLS6.0 Performance Pack error

Hi,
I have a Fresh install under Solaris and when I start the Weblogic Server 6.0
I have this error

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

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

When booting WLS 6.1 SP3
with JAVA_HOME=/home/bea/jdk1.3.1_02
I get an IncompatibleVMException
¿is this because WLS 6.1 is not supported on RedHat 7.3?
(WLS70 boot ok:)

thank you

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,

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?

Unable to load performance pack using JRockit 26.3 on Solaris 10

Hi all,
I'm getting the following error when starting up my WebLogic 9.1 server instance on Solaris 10. I've recently upgraded from Sun's JVM to JRockit 26.3. I do not get this error when using Sun's JVM.

libmuxer.so libweblogicunix1.so wlkeytool
libnodemanager.so libwlenv.so
I also have a sparc64 directory with the same file names.
Can anyone shed some light?
Regards,
Daniel

JRockit on Solaris is 64-bit so it needs the 64-bit performance pack files, so you need to have $WL_HOME/server/native/solaris/sparc64 in the LD_LIBRARY_PATH instead of $WL_HOME/server/native/solaris/sparc

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'

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
the number of requests per day / hour or the current moment.
The intention is to use this for reporting from the administration point of

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.

Socket BEA-000438 Unable to load performance pack.....

We are very familiar with this message and in general know how to resolve this.
We are seeing this on WLS 10.3.4 64 bit, on AIX 7.1, on Java 1.6 64 bit SR9_FP1.
The weird thing is that if we switch to Java 1.6 SR9 (not FP1) things are fine. First level of Oracle support was flabbergasted that some one is running WLS 10.3.4 on AIX 7.1 !!!!!! Anyway, that confusion is all taken care of now. Technically, this is a supported version. But still no good answer, other than a suggestion to contact IBM (the Java vendor). That is going to be a mountain to climb.
Anyone has any thoughts? Why would this version of Java find it difficult to load the .so files?
Thanks

 Can you post more details ?

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.

Hi,

Unable to load performance pack. Using Java I/O instead. Please ensure...

Hi there.
I am running WL 1033 development version using 64-bit 1.6.1 jdk (jdk-6u21-windows-x64) and the performance is terrible. I have upped my mem settings to this:
set MEM_ARGS=-Xms1024m -Xmx1408m -XX:PermSize=1024m -XX:MaxPermSize=1024m
and after a couple of deploys, I still get out of memory errors.
I notice this message on startup: <BEA-000438> <Unable to load performance pack. Using Java I/O instead. Please ensure that wlntio.dll is in:
Could this be part of my performace issues? If so, how do I fix it?
I followed the install directions in the README.txt file from this zip file: wls1033_dev.zip

Hi Mike,
If you are using 64 bit of Windows Operating System then Make sure that you add the following directory in the *"java.library.path"*....
Directory: E:\bea1033\wlserver_10.3\server\native\win\64
Example: In your servers start Script please add the following MEM_ARGS or in JAVA_OPTIONS:

set MEM_ARGS= -Xms1024m -Xmx1408m -XX:PermSize=1024m -XX:MaxPermSize=1024m -Djava.library.path=E:\bea1033\wlserver_10.3\server\native\win\64
Thanks

Unable to load performance pack, using Java I/O instead

I'm writing because we're having some troubles with the performance pack load.
We're getting this error message when the server starts:
<Feb 1, 2005 11:30:26 AM CST> <Error> <Performance Pack> <Unable to load performance pack, using Java I/O instead.
Please ensure that libmuxer library is in /bea/jdk131/jre/bin/../lib/PA_RISC2.0/native_threads:/bea/jdk131/jre/bin/../lib/PA_RISC2.0/server:/bea/jdk131/jre/bin/../lib/PA_RISC2.0:/siven/shlib:/bea/wlserver/lib/hpux11:/bea/wlserver/lib/hpux11/oci816_8:/usr/lib
java.lang.UnsatisfiedLinkError: getBuildTime
We have checked the following things:
1.- The library libmuxer.sl exists in the path: /bea/wlserver/lib/hpux11
2.- The file has the correct privileges so it can be read by the server
3.- We've run an 'nm -o libmuxter.sl |grep getBuildTime' to ensure that the method exists in the library
We have four managed servers running in the same machine and the error message apears only in one of them.
Any idea of what might be happening?
Does any one know on what OS librarys depends libmuxer.sl?
We're running WebLogic Server 6.1 SP6 on HP-UX 11.0

That's very odd that the same machine has 4 servers and only 1 sees this
error.
I'm assuming they all have the same environment/user etc. If not,
that's the first thing you should check.
I wonder if this is a resource issue in the OS. If you start a 5th
server, does it also see this error? Is it the 4th server you start
that hits this error, or just one of the 4 you run?
