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

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.Sounds like it can't find the library or one of its dependencies. I can't
remember if that's PATH or LIBPATH or LD_LIBRARY_PATH or what ....

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
pack. Is there any planned?Yes.
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
NativeIO pack, but I guess we were wrong.
Any help would be appreciated!

Performance pack on linux

I tried to install performance pack on Linux, the LD_LIBRARY_PATH is set and pointed to the correct location, but I got the following message when start weblogic server:
<Posix Performance Pack> Could not initialize POSIX Performance Pack.
<Performance Pack> Unable to load performance pack, using Java I/O.
We use Sun's 1.3 java(it could use native thread)
Many Thanks!!!!

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

Enabling performance pack

Hi,
How do I enable the performance pack for WL5.1 on Windows2000? I've so far
tried setting the path to point to weblogic/bin and that doesn't work.
Thanks
MC

Later service packs work with W2K. Earlier ones did not know that W2K was
actually just a newer release of NT.

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.PosixSocketMuxer.processSockets(PosixSocketMuxer.java:304)
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,
ranko

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
view.
Thanks in advance

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.....
Eric

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

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:

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.

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

Dear friends,
I am seeking help from you. When we start WL60 SP2 on Sun Soloris 5.6, we got
the following exception:

Hoever, the server itself started, and our applications runs ok
(at least so far). But this exception appears every time on some user accounts.
I was wondering what causes this exception. Some user accounts in the same machine
don't have this problem.
I also wondering if it will cause performance problem when the traffic is high.
We already applied the patches.
Any hits and suggestions are welcome.
Thanks in advance.

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.

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.

JMF and Linux Performance Pack

Following the Install Docs on
http://java.sun.com/products/java-media/jmf/2.1.1/setup-linux.html
i am trying to install the linux performance pack of the JMF.
However it exits without any response :(
Why could that be?
Installed: Sun JDK 1.6.0
System: Linux 2.6.20-gentoo-r3 SMP i686
EDIT: The Installer now starts. Maybe the file was corrupt, I used a newly downloaded one. BUT:
Now i have another problem:

How can I enable trace log in Oracle Database 10g ( in RedHat Linux)

Dear Forums Members,
Could u plz drop a message about how can I enable $Oracle_Home/network/trace
in Oracle Database 10g (Operating system is RedHat Linux Advanced Server 3).
I will very greatful if someone reply my message.
Thanks
Aungshu

To enable Tracing for a session Level.
ALTER SESSION SET TRACEFILE_IDENTIFIER = 'my_trace_id';
Enable the SQL Trace facility for the session by using one of the following:
SQL> Exec DBMS_SESSION.SET_SQL_TRACE
or
SQL> ALTER SESSION SET SQL_TRACE = TRUE;
To disable the SQL Trace facility for the session, enter:
ALTER SESSION SET SQL_TRACE = FALSE;
To enable Tracing for a database level.
Edit init parameter SQL_TRACE = TRUE.
Its not recomended because running the SQL Trace facility increases system overhead, enable it only when tuning SQL statements, and disable it when you are finished

Linux performance pack IOException: unexpected revents in poll

Yes, the server does not seem to be affected.
Here is my config:
WLS 5.1 SP5
Blackdown JDK 1.2.2 FCS
RH 6.0 with the following updated:
2.2.16 kernel
glibc 2.1.3

Interesting, I suspect that this message is benign. Does the server
continue to function properly after the message?
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.

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

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,
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?
