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.

Solaris performance pack

I'm running WLS 5.1 on solaris 2.7 and it seems that the performance I'm
getting is very poor. I turned the "weblogic.system.nativeIO.enable"
property to true/false and there's no difference. We're using WLS as an EJB
server only (no http).
Shouldn't the performance pack improve performance ?
Thanks.

Our clients all connect to IPlanet (hundreds of thousands ...), where an
IPlanet makes EJB calls to Weblogic Server. I know the connection to
weblogic is multiplexed, and I think we might have about 5 IPlanets per
Weblogic, i.e. about 5 sockets. In this scenario is there any advantage to
the the performance pack ?
Thanks,
Eran

The performance pack is really a scalability pack. You'll not seeimproved
throughput in a single server/client instance. What the pack allows us to
do is to better handle many many sockets. This gets around many of the
limitations of Java and socket handling. What you'll see what the
performance pack really shines through when you have to say like 1000
simultaneous clients.

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.
<May 16, 2006 9:16:38 AM EDT> <Error> <Socket> <BEA-000438> <Unable to load performance pack. Using Java I/O instead.

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
Bob

Does the sp8 performance pack work for Solaris?

I'm finally building our QA environment today, and I'll be setting up a
Solaris cluster...
I've just seen that the Linux and HP-UX performance packs no longer work as
of sp8. Is anyone using them successfully on Solaris?
thanks,

WLS is the onle process using these ports so it shouldn't hit this problem. Our
only recourse is then to reboot the server itself after which WLS starts okay.
Obviously we don't want to have to reboot the server everytime we shut down WLS.
Has anyone else encountered this problem? Any help greatly appreciated.
Thanks,
Garry

Hi.
Please open a case with support for this issue.

WLS is the onle process using these ports so it shouldn't hit this problem. Our
only recourse is then to reboot the server itself after which WLS starts okay.
Obviously we don't want to have to reboot the server everytime we shut down WLS.
Has anyone else encountered this problem? Any help greatly appreciated.

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.

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

I know about increasing thread pool size on a client and socket readers
but
was hoping we could use native.
This is weblogic 6.0 sp2
Also if this is not available in 6.0 is it available in 6.1 or going to

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?

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?

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-
Matt Groch

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!

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.

Solaris Intel to Solaris SunSparc Portability

Hi. Is anyone out there aware of any code portability issues for
a software application that is written on Solaris Intel and subsequently
deployed on a Solaris Sun Sparc workstation ?
Does the code need to be tuned ?
If needed, what is the effort required ?
Thanks.
Aran

The source code is the same for both versions of Solaris. As long as
your code doesn't make any ISA or endian assumptions, your port
should be nothing more than a recompile.
