Hi,
I am trying to create the oracle listener by running ./netmgr when I recieve the following error message:Do you start netmgr as oracle user and after setting all the relevant environment variables?
Can you find libnjni10.so file?
Please see if (Note: 301621.1 - Problem: Running EMCA Fails With 'java.lang.UnsatisfiedLinkError' on AIX When $LIBPATH Is Set Incorrectly) helps.

Problems with loading native library/missing methods:no ttJdbcCS in java.li

Iam facing one problem while connecting the timesten client to the server The SQL Exception which Iam getting is pasted below:-
Problems with loading native library/missing methods: no ttJdbcCS in java.library.path
I am working with MAC OS X 10.7.2 and my timesten client version is 11.2.1.0
I have also changed the Java Preferences from 64-bit to 32-bit but still whenever i tried to connect with the SQL Developer it gives me the above error.

I just tried this out. My environment is OS X 10.7.4, Timesten (32-bit) client 11.2.1.9.0, SQL Developer 3.1.07, Oracle Java 1.7.0_04.
The key things you need to be sure to do (in a terminal window) are:
1. Be sure to . in the TimesTen environment script <tt_install_dir>/bin/ttenv.sh to set the full TT environment.
2. Change directory to SQLDeveloper.app/Contents/Resources/sqldeveloper
3. Run 'sh sqldeveloper.sh -J-d32'
and all should be fine.
Note that if you are using Java7 as I am then there is a step 1a. Change the CLASSPATH environment variable to specify ttjdbc6.jar not ttjdbc5.jar. For some reason running the app directly from Finder does not work even if you add -J-d32 into the sqldeveloper launch script. I'm still looking into that.

Error ocurred during initialization of VM. Unable to load native library...

Hi,
I´m trying to install Oracle 9i on a PC with Suse 9.2.
when I put the first CD it comes with this error:
Initializing Java Virtual Machine from /tmp/OraInstall2006-05-04_11-13-11PM/jre/bin/java. Please wait...
Error occurred during initialization of VM
Unable to load native library: /tmp/OraInstall2006-05-04_11-13-11PM/jre/lib/i386/libjava.so: symbol __libc_wait, version GLIBC_2.0 not defined in file libc.so.6 with link time reference
I´ve seen that there was a similar issue in 2004 and I´ve trying to do what it says but it didn´t work this time.
Unable to load native library:
Could everyone help me to install Oracle??? I´ve been trying it for a few days and doesn´t work.
Regards,

I had same problems long time ago. Ok, I try to remember.
First I read the recommandation. You need a special GLIBC-Library to support the JAVA 1.1.8 runtime environment.
Some of the Oracle9i tools are compiled with gcc 2.95 compiler.
You may need gcc_old for SLES9 for linking of those tools.
gcc_old-2.95.3-175.2.i586.rpm is included in SLES 9 SP2 CD1
For Suse you can obtain a package called orarun. You will get further support for installing, starting and stopping ORACLE. Please look at http://ftp.novell.com/partners/oracle/docs/9205_sles9_install.pdf.
Good luck.

Problem with loading native library in java version "1.5.0_05"

My application uses a native coded drawing. With java version 1.4.xx it was working just fine but with java 1.5.xx it gives the following error at the time of loading native library:
java.lang.UnsatisfiedLinkError: /home/abyzov/tmp/friend32-1.6.02/libfriend.so:
/home/abyzov/tmp/friend32-1.6.02/libfriend.so: undefined symbol: XtWindowToWidget
I assumed that java loads all necessary X-libraries at start up but it seems to be not true for version 1.5.xx. Does anybody now about this kind of problems? Should I report it as a bug?

I have this exact same problem. I developed an application all along using 1.4.2_08 to be exact no problems. I was forced to switch to 1.5.0_06, now when I try to run the app I get:
java.lang.UnsatisfiedLinkError: <path to library>/libcomlib.so: <path to library>/libcomlib.so: undefined symbol: yp_get_default_domain
I have tried compiling it in both 1.4.2_8 and 1.5.0_06 and it compiles perfectly but when I run with 1.5.0_06 it messes up.
If you found the problem with this or anyone else has any advice please let me know.

Weblogic 8.1.6 Unable to load native library: libjvm.so

hi,
i have installed weblogic 8.1 SP6 on my box and when im trying to deploy new application i get errors comaplining about some java libraries.
when i link them to the /usr/lib directory it's working but it's not a solution couse i need also weblogic 9.2 server running on that box.
i tried to export LD_LIBRARY_PATH with path to the jdk142 that was installed with weblogic server by myself but also without any success.
i checked commEnv.sh file and found that path to java libraries are not set properly. added those paths to the LD_LIBRARY_PATH but after running WLS when i try to echo ${LD_LIBRARY_PATH} i get no results.
maybe someone had such problems, and knows how to resolv them.
my system is Debian Linux/stable
WL_HOME=/home/bea/bea/weblogic81
JAVA_HOME=/home/bea/bea/jdk142_11
added to commEnv.sh:
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/${JAVA_HOME}/jre/lib:${JAVA_HOME}/jre/lib/i386:${JAVA_HOME}/jre/lib/i386/server:${JAVA_HOME}/jre/lib/i386/client

PS. sorry for my english and is this post is not in the place where it sould be ;-)

SOLUTION:
set the absolute path to javac in General Section of the configuration
make sure that you j2sdk1.4.2 is accessible by all uids that managed servers are running at.
if that wont help try to put your J2SDK in /usr/local/java.
and reconfigure your administration server.
i hope that will help you all that have same problems. cheers ;-)

Problems with loading native library missing methods ttJdbc1122.dll

Problems with loading native library/missing methods: C:\TimesTen\tt1122_64\bin\ttJdbc1122.dll: Can't load AMD 64-bit .dll on a IA 32-bit platform
Hi,
I have installed TimesTen 11.2.2 64-bit version on 64-bit windows 7.
I have TimesTen 7 64-bit as well installed on my machice
When trying to connect to TimesTen (Direct connection) using jdbc from eclipse, I get the following error "Problems with loading native library/missing methods: C:\TimesTen\tt1122_64\bin\ttJdbc1122.dll: Can't load AMD 64-bit .dll on a IA 32-bit platform".
The JDK version is 1.6.25 - 64 bit version.
Please help me resolving this error.
Thanks in Advance,
Balamurugan

Are you using SQL Developer?
There is or used to be a restriction of only being able to using 32 bit. A suggestion might be to try the 32 bit client.

Unable to load native library on HP-UX

Hi All,
I am using a third party java library on 64 bit HP-UX, which in turn uses some native libraries. However, when I use that 3rd party java lib in my java app, I always get an UnsatisfiedLinkError, indicating that it cannot locate the native library.
The name of this native library is "libjcryptoki.sl". The 3rd party lib correctly calls System.loadLibrary("jcryptoki") internally, and libjcryptoki.sl file name is present in SHLIB_PATH, LD_LIBRARY_PATH.
Also, according to HP-UX JNI documentation, all JNI shared libs MUST begin with "lib" and should be of type "sl", which is satisfied here in this case.
Anybody has any idea as to what could be missing?

AUTOMATON wrote:
Anybody has any idea as to what could be missing?Presumably you get the error from the loadLibrary() call and not after it. If not then the following is pointless...
No idea why but you can try System.load() instead providing a full and explicit path and file name.
Now if that works it means that the name is wrong somehow with loadLibrary() (maybe a VM problem, maybe a library name problem.)
If it doesn't work then that would suggest that something is wrong with the library itself. Could be a large number of things.

Error Loading Native Library on Mac, but not XP

In a program that I am making, I use JOGL and Odejava. Testing on Mac and Windows works fine loading JOGL's native libraries. However Odejava fails to load on Mac OS X but works fine on my Windows machine.
The only difference is that JOGL uses just .jnilib's while Odejava has a jnilib as well as a dylib. All the jnilib's and dylib's are in the home directory. I also placed libodejava.jnilib into /Library/Java/Extensions and ode.dylib into /usr/lib/ as per the installation instructions for Odejava.
When I try to run I get this error:
java.lang.UnsatisfiedLinkError: /private/Network/Servers/students.central.spps.org/Users/idoneus/Documents/workspace/Idoneus_.03/libodejava.jnilib:
The only three possible things that I could think of are that
a)libodejava.jnilib has been corrupted, but I doubt that since I keep redownloading it.
b)The Mac computer is in a lab that users remote access to a server for users, which might possibly confuse Java.
c)libodejava.jnilib wasn't built correctly to actually look for the dylib
Your help would be appreciated because I'm at my wits end.

Problems with loading native library/missing methods: no ttJdbc1121 in java

Hi,
Can anyone help me? I keep getting this error when trying to start my jboss server. I have no problem with this when i run my standalone java application. My jboss version is 4.2 and my timesten version is 11.2.1.6.1 . My oracle version is 10G express edition. Any ideas?
Thank you very much.

The TimesTen JDBC driver is not a pure Java driver. It requires to load several native code libraries. Most appservers have to be told what directories to search for those libraries (a bit like the O/S LD_LIBRARY_PATH variable). This error occures when you have not told the appserver where to look to find hte native code libraries (<tt_install_dir>/lib).
I'm not a JBOSS expert so I can't advise you on this; you need to consult the JBOSS documentation to find out what parameter/setting you need to modify to fix this.

Loading a 32-bit native library on a 64-bit JVM environment

Hello
I have a 3rd party 32-bit native library (abc.so). I am creating a JVM from my 64-bit C code (myC.c). Within this JVM i try to load the 32-bit abc.so
I get the following run-time error
Exception in thread "main" java.lang.UnsatisfiedLinkError: abc.so: ld.so.1: myC: fatal: abc.so: wrong ELF class: ELFCLASS32
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1480)
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1404)
at java.lang.Runtime.loadLibrary0(Runtime.java:772)
at java.lang.System.loadLibrary(System.java:832)
When I try to load the same abc.so using a wrapper Java code(instead of myC.c) by running it with java -d32, it works ok.
Do we have any option that we can set while creating a JVM from C, with which we can allow it to load 32-bit native libraries?
Moreover do we have a list of all the options that can be set in the JavaVMInitArgs?
I am using Java 1.4, as 1.3 doesn't support 64-bit JVM.

Rahul

Hi,
I was also having a problem under 64 bit, Now I am certain that if ur Java code makes a call to the DLL, make sure that DLL is compiled under 64 bit compiler and not 32 bit compiler. This is the mistake I made and the JVM was throwing unsatisfied link error. Now this DLL (compiled under 64 bit) could call a 32 bit dll, I dont think that should be a problem.
Hope it helps.

[XMLType]Native Library already loaded

Hi !
I work with oracle DB 9.2.0.3 and J2ee server.
I connect to the db with JDBC driver (oci8 client)
When I use the method CreateXML method (XDB.jar package) I have this error :
java.lang.UnsatisfiedLinkError: Native Library D:\oracle\ora92\bin\orageneric9.dll already loaded in another classloader
I have to shutdown and reopen my J2ee server ...
Any Idea ?

If you use the session of the myserver1, then store some value in session to identify that the library is loaded.
As a first step in myserver2, Check in session whether the value is set.
If you cannot propagate session information across myserver1 and myserver2, then
myserver1:
static
loadLibrary("YourDLL")
"Include this here..........."
This code will be there in some class
"Include this here..........."
Just write in ser file that DLL is loaded.
myserver2:
static
checkWhetherAlreadyLoaded();
loadLibrary("YourDLL");
Or have the loading of library alone in a class in a static method.
public class LoadClass
public static loadLibrary()
System.loadLibrary("YourDLL");
In myserver1, just call this.
In myserver2, before calling this method,
just call any native method - a test method will do
public boolean checkLoadedStatus()
try
// Call the testing nativemethod.
catch(UnsatisfiedLinkerError e)
try
LoadClass.loadLibrary();
return true;
catch(Exception e)
return false;
}

have you any solutions?

You are having some problems with that Oracle Driver and Orion.
Do you have any JSP at your Installation that work with Oracle?
Orion needs to know where that Diver is located is that Driver in
some package that is in Orion's Class Path?
