Linux Performance Pack

Rob,
I hope you get to see this message. I tried the Performance pack
for Linux on WLS 5.1.0 SP3 posted on this newsgroup on 04 Jul.
libmuxer.so is put inside /weblogic/lib/linux, which is also in my
$LD_LIBRARY_PATH. I still get the error/warning:
Wed Jul 26 22:26:18 CDT 2000:<E> <Performance Pack> Unable to load
performance pack, using Java I/O.
Please advise if you need any info.....

Hi,
My Linux runs
* Redhat 6.1
* Sun jdk 1.2.2
I guess that it must be the native vs. green threads problem here.
I remember that Sun Linux jdk 1.2.2 only supports green threads. Does that
mean I have to use other jdk like IBM's?
Thanks

Strange, it works fine here.
Did you export LD_LIBRARY_PATH (if you are using a sh variant)?
Can you provide as much information about your environment / jvm as
possible?
Also, you should know that the performance pack will only work with java
vms which use native threads. I

I have just come across this problem installing jmf-2_1_1e-linux-i586.bin.
You can get around it by editing the installer BEFORE running it (use vim or gvim with the -b option as it is a partially binary file).
On line 267 there is the offending command 'tail +309'. Change this to 'tail -n+309' i.e. tail from line 309 onwards, hence skipping the install script itself.
Save the file and run it again.

Yes, the server does not seem to be affected.

Interesting, I suspect that this message is benign. Does the server

Also, what java vm are you using on Linux? I believe only the native
threads jvms will work correctly with the performance pack. IBM's 118,
IBM's 130, sun's 130, and Blackdown's 122 are all native thread
implementations.

Linux performance pack jmf2.1.1e is damaged

The download for the linux performance pack of the java jmf2.1.1e is damaged and needs repair.
Does anyone know someone at Oracle to contact and report the error ?

To report it you'll need to disclose the link to exactly which download you are trying to get, and the type of workstation you're installing to.
You need to make sure you match the word size. e.g. 64bit download to 64bit workstation.

Following the Install Docs on

Why could that be?

Can't enable performance pack on Linux

I am trying to enable the performance pack on Linux 7.1 with
WebLogic Server 5.1 sp 12, but see the following in the log
when I start the server:
Unable to load performance pack, using Java I/O.
I have tried setting the java.library.path to point to the linux
.so folders (per BEA documentation), but still does not seem to work.
Any help would be greatly appreciated. Thanks!

If memory serves, on Windows it's $PATH.
On Solaris and Linux, it's $LD_LIBRARY_PATH
On HP-UX, it's $SHLIB_PATH

Performance Pack for Linux

Hi all,
I am trying to install Weblogic 4.5.1 on Red Hat Linux 6.1
When I set the weblogic.system.nativeIO.enable to true within the
weblogic.properties file, I receive an exception:
java.lang.UnsatisfiedLinkError: no muxer in shared library path
(libmuxer.so)
I tried looking through the installation documentation and was unable to
find anything related specifically to using the performance pack under Linux
(there was information specific to AIX and Solaris, however).
So I guess my question is: Is the performance pack supported for Linux? If
so, what might I have to modify in order for it to work correctly? Thanks-

Hi,
I just saw your post about there being no Linux NativeIO performance

If so, could you provide a general
timeline?
It should be available in the Denali (5.1) release of WLS or shortly
thereafter. Denali is GA at the end of March.

BTW, Can you enlighten me as to what the libWeblogicLinux1.so file do
that is in the linux directory?I believe that it is some platform-specific debug code that we include.

We were hoping that this was the

If you are on SP 7 or 8 the performance pack doesn't work. Have you tried this on 6 or less?

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:

I also have a sparc64 directory with the same file names.
Can anyone shed some light?

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

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.
