Ramesh & Kumar,
I got the same error when I tried to run WL Server 6.1
on my Windows 98. Here is the complete trace. Is this
error something that can be ignored because it sounds
like it is something just for performance.

It appears the following stack trace is incomplete.
I can't believe the stack trace is originated from PosixSocketMuxer.
posix is only for unix platform.
In anycase before loading a performance pack we check the OS and
based on that we will load the appropriate dll/shared library.
AFAIK, performance pack is not certified on 98.
That's why it's failing.

Thanks,
Tim PerrigoThis 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.

Re: UnsatisfiedLInkError: No muxer in java.library.path
In the default weblogic.properties file, this should be the first property
listed under the System Properties section:
# SYSTEM PROPERTIES
# System properties in this section are set to system defaults
# Performance pack. The shared library must be accessible from your
# PATH (NT) or from your shared library path (UNIX; the name of the

weblogic.system.nativeIO.enable=true

"no ocijdbc11 in java.library.path" error when connecting a TNS database co
Hi
"no ocijdbc11 in java.library.path" error when connecting a TNS database connection
I have the same problem 'error code' when testing the connection to a database although I have an APEX db that connects without a problem.
I have re downloaded jre & SQL Developer just to ensure all files are where they should be with no luck.
I've also tried most of the suggestions in various threads.
Does anyone know what exactly causes this error?
eg; should I be looking for a file called 'ocijdbc11' & put it into the 'java.library.path' path?
Can anyone explain to a newbie at db connections what I should do?
I'm using the 'thin' client as the checkbox is clear & I don't know what path to enter into the correct file to make this work??
This is & needs to connect as a TNS connection & was working fine until recently, the only change I can think of is a move of files from the 'C' drive but I thought redownloading SQL Developer would slove this.
ThanksWhen you reinstalled SQL Developer, did you install into a new directory (ie rename or delete the old directory first)?
I don't know if system setup contains directory references (which might be invalid after moving the location of SQL Developer). Does renaming your system2.1.1.64.45 directory (in C:\Documents and Settings\username\Application Data\SQL Developer) help? Note that your connections are in the connections.xml file in the o.jdeveloper.db.connection.11.1.1.2.36.55.30 subdirectory of system2.1.1.64.45 - you will either need to export connections before renaming and then import again after or copy this file to test if you can connect.
Finally, the TNS Names directory preference is just a way of telling SQL Developer where to look for the tnsnames.ora file, rather than just assuming it will pick the right one. If you go to create a new connection, do you get the right list of TNS aliases? If not, then set this preference to the directory where the right tnsnames.ora file lives.

I have the so file in the path and the file name is spelled correctly. Java still complains that the so file is not in the java.library.path. I used System.loadLibrary("Java_xDVDFSReader"). Is it possible that my so file is messed up? I included the gcc command I used to make it. I'm not familar w/ gcc so I'm not sure if the error comes from a "messed up" so file or not. Any suggestions? TIA

Error "no ocijdbc11 in java.library.path" in SQL Developer 4
Hi!
I have just installed the latest version of Oracle 12c and the latest SQL Developer (4.0.0.12). I have also JDK 7u25 installed. I run everything on Windows 7 64bit. When I create a local connection in SQL Developer and test or try to connect I get the error: no ocijdbc11 in java.library.path
If I try the exact same thing in SQL Developer 3.2.2 (the one bundled with the latest Oracle 12c) it works fine. In both versions of SQL Developer I have done no configuration and all the settings are the defaults.
I have read all the posts that relate to this error message, but they are all based on older versions or other platforms.
Is there a problem in the default configuration of SQL Developer 4 or a compatibility problem with Oracle 12c? Any ideas of how to fix this?
When I compare the properties of the two versions of SQL Developer I see that most of them are identical, but the java.library.path points to the sqldeveloper/bin directory in v4 and to the sqldeveloper root folder in v3. I don't know if that is significant.
Also the setting "Use OCI/Thick Driver" under "Database: Advanced" is unchecked, so it seems strange that it tries to use it anyway.
/nikosNikos:
You should search that ocijdbc11 is installed in a path similar to C:\Oracle32bit\product\11.2.0\client32bit\bin and that this path (or C:\Oracle32bit\product\11.2.0\client32bit) is in your java.library.path.
If you click on Help|About and the Extensions tab you will see a list of some of these.
Click on the Export button and copy the contents to a file or clipboard. Open the file (or Ctrl/V) in an editor and search for java.library.path. This is the list of ;-separated folders that SQL looks in. Ensure that this list includes the one where your ocijdbc11 was found.

I have WLS 5.1 SP10 running successfully on all platforms (Solaris,
HP-UX, NT/2000 and AIX). On AIX, I am unable to communicate with the

I haven't tried 5.1 on AIX, but I know in 6.0 there is an error in startWebLogic.sh
specific to AIX: it exports "LIB_PATH" when it should say "LIBPATH". I just checked
in the 5.1 script and it appears to have the same error. You need to change the
name "LIB_PATH" to "LIBPATH". This error is fixed in 6.1 so we can be sure there
is at least one other person on the planet who is trying to use Weblogic on AIX.
:-)Tom,
Thanks for the help. Unfortunately, I cannot find a reference to
LIB_PATH in setEnv.sh or startWebLogic.sh. At this point, we are
pursuing the possibility that the IBM JDK 1.2.2 introduced some
incompatibilities. From the "IBM AIX Developer Kit, Java TM2
Technology Edition, Version 1.2.2 README":
"Because of incompatibility between the IBM AIX Developer Kit, Java
TM2 Technology Edition, Version 1.2.2"..."JNI executable programs,
including third-party software packages and those built for previous
Java software releases on AIX, that were built without this binder
option are NOT compatible with the JVM in this
release"..."Compatibility of an executable program can be verified
using dump -ov The stdout output will show the modtype to be "UR"..."A
script file (convertJNI) is shipped in the directory
/usr/java_dev2/sdk/sh. This script will help you to convert the
modtype to UR in the optional header of your JNI executable programs
without having to recompile the code."
Out of the hundreds of potential files, which need to be converted?
Based on additional information obtained by running in verbose mode,
we were able to gather the following:
java.sql.SQLException: System.loadLibrary threw
java.lang.UnsatisfiedLinkError
with the message '/apps/weblogic2/weblogic/lib/aix/oci816_8/libweblogicoci36.a:

We performed the dump -ov on each and each reported a modtype of RE

We backed up libclntsh.a and libweblogicoci36.so, converted one at a
time, and ran the dbping after each. No such luck. Any ideas on how
we can find the JNI needle in the haystack?

If you UNCHECK that during install they will show up in the JMF/lib directory.

Hope it helps. I've been going nuts until I just figured that out.Hello,
thanks for the tip - I followed your instructions and have the dlls. However, when I try running some code, this error occurs:

I cannot find dll's compiled for 64-bit on the Internet; has anybody else faced this problem?
