NWA Java Stack Trace: TechnicalLockException (Acknowledgment IDOC-PI-JMS)

Hi,
I got this error for each incoming message in the NWA Java Log, any idea what is the cause?
We had a server crash and the tech sys says everything is back to normal, but I doubt it.
com.sap.engine.frame.core.locking.TechnicalLockException: Cannot lock [I2011032313330536700000<host.domain>...........707125250, $service.msg_BC_MSG, EOIO_MD_XI_INBOUND_MMFSERIALIZE0077__BS_SYS1_DVE, X]; unknown return-code (returncode = -1).

The interface is "working" but it took about 4 hours to get the acknowledgment back.
Any idea?
Thanks,

Hi Martin,
com.sap.engine.frame.core.locking.TechnicalLockException: Cannot lock
The problem might be caused by an overflow of internal resources in the enqueue server process .
Pleaser refer the notes#834589 and # 956870 to solve your issue.
Cheers!!!!

No line numbers in stack trace from Java Stored Procedure exception

I have a Java Stored Procedure which can generate an exception. In one database (11.1.0.6) the Java stack trace contains line numbers for my code, but not for the classes loaded by default with the JVM. In another database (same version) the Java stack trace does NOT contain line numbers for my code, but does contain them for some of the classes loaded by default with the JVM!
Neither of the schemas where I am running the the Java stored procedure has a JAVA$OPTIONS tables as described here:
http://download.oracle.com/docs/cd/B28359_01/java.111/b31225/chtwo.htm#BABIGFGA
So the Java should have been compile "-debug" by default in both schemas. I specifically set the debug option to true using:
exec dbms_java.set_compiler_option('', 'debug', 'true');
but this had no effect.
Can anyone explain this behavior or tell me how to always get line number in the Java stack trace?

Hi,
Try using java.util.logging package. Using these packages you can configure your logging information to include context down to the class name. Then each log message would be unique enough to know where it came from.

WLST, how do I suppress unwanted stack traces and make WLST less verbose?

Hi everyone,
I've just started out with WLST but have ended up somewhat confused. My script works as intended but is very verbose.
Suppose I want to log in:
try:
     connect(user, "wrong_password", url)
except WLSTException, err:
     print str(err)
     print "Run with option \"-h\" for help"The password is wrong so I get something like this printed out by me:
{noformat}
Error occured while performing connect : User: wm714, failed to be authenticated. Use dumpStack() to view the full stacktrace
{noformat}
But I also get a totally unwanted Java stack trace (before my message):
{noformat}This Exception occurred at Fri May 21 15:49:01 CEST 2010.
javax.naming.AuthenticationException [Root exception is java.lang.SecurityException: User: wm714, failed to be authenticated.]

at weblogic.jndi.WLInitialContextFactoryDelegate.pushSubject(WLInitialContextFactoryDelegate.java:677)
{noformat}
I don't want to confuse the user with all that! I found this:
http://objectmix.com/weblogic/529822-wlst-exception-handling-unwanted-stack-trace.html
Which discusses WLS.commandExceptionHandler.setSilent(1) I'm running on WLS 10.3.0.0 and can execute that statement but it has no effect. I didn't even know about the WLS-object and I can find no documentation on commandExceptionHandler.
On the matter of verbosity, is there any way to get rid of stuff like:
Location changed to domainRuntime tree. This is a read-only tree with DomainMBean as the root.
For more help, use help(domainRuntime)I avoid using the "interactive" commands like cd and use stuff like getMBean("domainRuntime:/ServerRuntimes/" + appServer.getName()
+ "/JMSRuntime/" + appServer.getName() + ".jms/JMSServers") but I still get the clutter printed out.
Thanks!

Workaround:
wlstOut = tempfile.mktemp(suffix="_wlst.txt")
redirect(wlstOut, "false")
... do useful stuff
stopRedirect()
os.remove(wlstOut)I would have preffered to turn off the messages (yes I could try /dev/null) but this will do. A funny thing is that the stack trace I wrote about doesn't appear in the log file. Somehow "redirect" must have a nice side effect.

NullPointerException without stack trace

The Java stack trace can be very suitable to find the error path. However, I get NullPointerExceptions without a stack trace! If I catch a Throwable in my main() method I can print the exception, but the stack trace is empty:
try {
} catch (Throwable t) {
System.out.println("ERROR: "+t); //does print "java.lang.NullPointerException"
t.printStackTrace(); //also just prints 1 line with "java.lang.NullPointerException"
}I thought, a stack trace is always available?

When I want to add a comment to this "RFE" (!!!), I just get a "We encountered an unexpected error. Please try back again. " ... there are "fixed" bug ID links:
Release Fixed 1.4.2_05(Bug ID:2120657) , tiger-beta2(Bug ID:2120658)
But I use 1.4.2_05 and it happend there ...

How to get Java source in applet stack trace to debug Java security manager

How can I get line numbers for Java source in stack traces for my applet? I'm having a problem with my code-signing certificate. On one of my applets, I consistently get a NullPointerException inside the security dialog code in the JDK. As a result, either the "trust this applet" dialog never appears, or even though it appears, it defaults to untrusted because of the exception, so I can't access any local files (and that's a bit of a problem for an applet whose sole purpose is to upload files to our server). I unzipped src.zip in my JDK directory and set the debug flag for my Ant <javac> task as well as set debuglevel to "lines." Anything else? Here's the trace that I'm getting so far. See that after the NullPointerException it assumes that the user has denied permission. If I could read this Java source maybe I could figure out why it hates my code-signing certificate (jarsigner, BTW, never complains when I verify my jar).

Rats, now that I look at the stack trace and compare to what's in the JDK srce.zip, it appears that most of this code is not part of the JDK source. I don't see any com/sun/deploy, etc.

[ ERROR ] CFG-ERR-0103 Unable to start IBM Cognos 8 service.
Execution of the external process returns an error code value of '1'.Not sure where went wrong. Already followed many suggestions are already there in different sites. But, so far no luck.
Is there any path I need to add in CLASSPATH other than what I have?
Also, check few oracle docs regarding the same. But, nothing can eliminate this problem.
Can you please suggest?
Really appreciate your time for reading this.
Thanks.

What caused the "java.lang.OutOfMemoryError (no stack trace available)"?

We just met another problem: after I modified the BDM file on TUXEDO and bdmconfig.xml
file on WEBLOGIC (with no ACL or authentication setup on both side), when I booted
up the WebLogic 6.1 server, the ULOG file of Tuxedo says that the connection has
been set up, however, I got the "java.lang.OutOfMemoryError (no stack trace available)"
on the WebLogic side. I tried to enlarge the Java heap size even to 1024m, but it
has no use. If I delete the WTC setting then WebLogic works fine.
Could somebody helps me on this? Because we have a very tight schedule on development,
I do appreciate your quick response.
Thanks!
Bill

Hi,
I am getting same OutofMemoryError. I could not understand change in bdmconfig.xml
removed the outofmemory error.
what is bdmconfig.xml file and you specified port#?
I could not able to see any port # in the config.xml...
any help is appreciated.

Another expert in our company told me that we should use a different
PORT# (kind
of DUMMY port) in the bdmconfig.xml file on WebLogic side, instead of
the real WebLogic
instance PORT#. We tried and the OutOfMemoryError disappeared, and the
WTC connection
works OK. We don't know why should we do this, maybe it is a bug or some
hardware
requirement.
Anyway, thank you very much for your help and quick respondse!
have a good day!

Bill,
Check the logs to see if the out of memory is the only execption orif
it is the last exception. It could be that there is something happening
earlier on that you are missing.
There are also other JVM problems that can arise besides the heap
size. The Hotspot VM had an issue where you needed to set a maximum
permanent generation size( helps garbage collection tuning I think).
(-XX:MaxPermSize=32m for jdk130,64m for jdk131). It comes into
play when you are loading many classes.

Bob,
Thanks! We didn't set MTYPE in both BDMCONFIG files in Tuxedo and
WebLogic
sides.
From the WTC document and Tuxedo document, it says that if MTYPE is
not
specified,
the default is to turn ENCODING/DECODING on. Do you see any other
possibilities?
Thanks!

Bob Finan <[email protected]> wrote:
Bill,
One possible reason is if MTYPE is set, in the DMCONFIG on the
Tuxedo side, as part of your remote domain definitions of the WTC
domain. This should not be set or set it to NULL. This problem occurs
because encoding/decoding is always needed between java and non-java
domains.

We just met another problem: after I modified the BDM file on TUXEDO
and
bdmconfig.xml
file on WEBLOGIC (with no ACL or authentication setup on both side),
when
I booted
up the WebLogic 6.1 server, the ULOG file of Tuxedo says that the
connection
has
been set up, however, I got the "java.lang.OutOfMemoryError (no
stack
trace available)"
on the WebLogic side. I tried to enlarge the Java heap size even
to
1024m,
but it
has no use. If I delete the WTC setting then WebLogic works fine.
Could somebody helps me on this? Because we have a very tight scheduleon development,
I do appreciate your quick response.

Can java.util.logging.SimpleFormatter log stack trace?

can java.util.logging.SimpleFormatter log stack trace? I hope I don't have to write a custom formatter.
-yc

right, it does, the code I am modifying prints regular log msg at LEVEL.SEVERE, that's why it doesn't have any stack trace.
By the way, I am using file name pattern, aName.log%g, why it the most current log is aName.log.0, rather than just aName.log. In the conf file, I have,
mypackage.myclass.logfile.name=/.../aName.log.%g
java.util.logging.FileHandler.limit=60000
java.util.logging.FileHandler.count=3
java.util.logging.FileHandler.formatter=java.util.logging.SimpleFormatter
Thanks.

What are the steps required in NWA and ID in order to enhance security of adapters in PI 7.31 Java Stack ?

HI All,
I am looking for steps need to follow for seurity and certificate management in PI 7.31 Java Stack.
Could someone help me with the security and certificate management steps needs to follow for SOAP/RFC/MAIL adapter ?
I looked at sap help link Network and Transport Layer Security - SAP NetWeaver Process Integration Security Guide - SAP Library
Regards,
Karan

Hi Karan,
For SOAP adapter you can use digital signing and encryption. Please refer the below blog
Configuring WSSE (digital signing and encryption) using SAP PI 7.11 AAE SOAP Adapter

Java Exception Stack Trace

Whenever an exception object is created, its constructor is called. This constructor, calls super class constructor to fill in the exception stack trace and then the constructor uses printStackTrace() method to print the stack trace.
This should print the stack trace automatically on the std out.
However, in our exception handling code, unless we specifically use printStackTrace() it does not print stack trace.
What is the reason for this?

Hi,
I am aware that not all Exceptions print stack trace to std out.
I am specifically refering to SQLException. The constructor source code is
public SQLException(String reason) {
     super(reason);
     this.SQLState = null;
     this.vendorCode = 0;
     if (!(this instanceof SQLWarning)) {
     if (DriverManager.getLogWriter() != null) {
          printStackTrace(DriverManager.getLogWriter());
}

Make java run without printing the stack trace

I have a GUI program which appears to work for all test cases. Basically what it does is prints out data from a linked list allowing the user to traverse the list with Next and Previous buttons which call a list iterator next/previous method call, and then display the current item in the list. The original problem arose when dealing with alternating calls to next and previous, which since list iterator does not have a current pointer, returned the same element ad infinitum. I modified the method to check for alternating button presses, and it seems to work, except for cases where there are two elements in the list. In this case it still works, printing the correct element, but it also prints to the command line an Exception in Thread AWT...NoSuchElementException. My question is, is there any way to tell the program to not print out this stack trace and just keep running quietly through the Exception?

I'm not an expert at error handling, but wouldn't it work to put the code that throws the exception in a try/catch block?
like
try {
//code that causes exception
} catch (NoSuchElementException e) {
//do nothing
}Might not work, but it's worth a try...

Java Stack Vs Dual Stack in Pi 7.3

Hi experts.
I open this thread because I'd like to know your opinion about the newJava installation option in SAP PI 7.3. In previous realeses (7.0,7.1) I felt more comfortable and safe in abap stack and I'm a little afraid about working only with java stack.
I'd like to know advantages and disadvantages to choose java stack instead of dual stack, why you'd choose one of two options or both in your nexts customers.
Thank u so much and happy new year!!!!

Java Stack or Dual Stack in 7.3
Java Stack alone: Almost all standard adapters including HTTP, IDOC and Proxy are all available in this stack. you need to use Integrated Configuration object for this. You are basically going to use Advance Adapter engine alone for the entire processing.
Pros:
No persistance steps here. So you would improve performance many folds for sure.
Throughput is also improved very much.
since 7.3, Solution Manager is available for monitoring inaddition to RWB and NWA. So monitoring would not be issue.
If you are looking for real performance improvement, Single stack Java to go.
Cons:
Abap mapping is not supported.
Message split to multiple receivers are not completely supported.
BPM interfaces are not seamless migration here. SAP 7.1 and lower versions support BPEL wheras 7.3 supports BPMN standards. So you might have to tweak a bit to modify existing interfaces here
Dual Stack:
Your option is pretty open. If you need some specific interfaces to handle only java stack, still that is possible and increase the performance. Also if you have lot of existing interfaces that requires BPM interfaces, ABAP mapping , Multiple split /branching etc.
still dual stack is the better option now. Here developer decides according to the requirement.
Still safe mode is going for Dual Stack for now and change in the future to single java stack alone.

PI Timestamp incorrect in java stack

Dear All,
In the java stack-> runtime workbench (Communication Channel Monitoring) the logs time stamp shows 1 hour back..
Whereas the same message log timestamp when checked in the abap stack shows the correct time.
All the default java logs which are shown in NWA(Monitoring -> Logs and traces) are also having a correct time stamp.
Below is the enviorment.
OS: Win 2003 x64
SAP PI 7.0 64 bit (SP12)
MSSQL 2005 64bit (build 9.0.3228)
JDK 1.4.2_17-x64
Please help asap.
Thanks in advance.

Hi
We have faced similar problem. We have applied note 919538 and resolved the same problem. We did following steps
1. Download the TZ_2008_V06.zip attachment locally
2. Execute program TZCUSTIM in SE30
3. Enter the path of the .dat file from the SAP note. This process should be done in every client.
4. Verify the new entry for the USA DST rule in transaction SPRO for Time Zones
5. A system restart is must
I am not sure if there is any other problem with the timestamps.
Thanks

Analysis of stack trace

Hi Experts,
i have an null pointer exception error in a message on adapter engine level.
It's allways the same message what occurs this error.
The message content in netweaver message monitoring contains following error:
Application error occurred during request processing.
Details: Error [javax.servlet.ServletException: null], with root cause [java.lang.NullPointerException: null].
Exception id: [0019B9F3058800A2000005E400001834000496E2E17B13EF]
I have read the sap note 859465. There is recommended to take a look in the stack trace.
Now i want to analyse the stack trace of the pi.
But i have no idea where to find that stack trace.
Can somebdy help me?
Many thanks!!!

if you are using PI 7.1, then use NWA and Java system reports/log viewer link to get details
or by default you can find them - /usr/sap/<SID>/DVEBGS001/j2ee/cluster/server0/log.

Third party application forcing java stack to restart when logged in through SSO

Hi
We have APW Third party application installed on Enterprise portal 7.4.
When we tried to login APW portal through SSO it forces Java stack services to restart.If we use APW directly without SSO it works fine.
Can you help me tto resolve the issue.

Hi Manish,
Please check the configuration once agian about the third party connection and the portal.
Also provide the "dev_server0" which under in directory /usr/sap/SID/J00/work and default trace which under in “/usr/sap/SID/J00/j2ee/cluster/server0/log" to analyze the issue. There is some other tool as well to check the issue using "httpwatch" log tool. But, mostly issue can be identified in dev_server0 or defalut trace".
Thanks,
Brindavan
