Performance Pack WL5.1

We are trying to use Solaris performance packs for WL5.1. The load library is
correct and all *.so files have execute privileges but still receive the infamous
'Unable to load peformance pack' message. Currently have SP13 applied. At this
point, we cannot move to 8.1. I am checking the newsgroup to see if anyone has
any suggestion on what else could be contributing to this problem. Thanks!

Re-installed SP and modified permissions on *.so files and problem solved. Thanks

Is there a way to isolate load of the performance packs in the weblogic
start
process?

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.

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.

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

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

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.

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.

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

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?
