Exception cant aable trap.

hi friends,
am back :) after a Long gap am here. any ways am glad to see you all :)
i made a application regarding HR related using jdev 11.1.1.5.0 using Business components.
i had a Exception while am commiting the data's. am out of work space. so am just post the exception.
java.lang.classcastexception java.lang.stackoverflowerror cannot be able to cast to java.lang.exception.this Exception arrives sometimes sometimes may not.
In My application i did some kind of validation in eo level and bean level. and some sort of operation.
i cant able to trap it. one day i taken a crazy decision :( comment all of the code snip. again throwing...
i feel that am not properly confguring of one of my checkbox. i correct that the exception went off. but now again throwing the error randomly.
please any one could explain me. i understood the exception what it is try to say. but how do i trap . eventhough i folded up all of the codes by try catch block.

i understood that
"The stack overflow would point to some recursive code loop happening"
i did know the error from which part of my code. but it popuping while commit sometimes.
i had db trigger for after insert or update or delete. throw some raise application error.
specfic db trigger recursive looping to check all the records which already present in same date.
i always handle or catch the db triiger and popuping up as user understandable message.
my question from which part of the / section (i.e db code , eo impl code vo impl code bean code am impl code )code this exception is raising.
how do i found out ?
is there any way. ?

Interface link trap in ios-xr

Hello,
How to enable interface link trap in cisco ASR9010? and how to verify it?
I have enabled it on my ios-xr, i"m getting all traps except interface link trap.
Thank you.

hi there,
yup possible, you may need to configure
snmp-server traps snmp linkup
snmp-server traps snmp linkdown
and

it could be your trap server doesn't like the cisco format of the trap hence that ietf may make that difference.

Raising exception for LONG variable

Hi
I am calling a procedure from HTML which passes data into a LONG
type variable. If the length of data is more than 32KB , NULL is
assigned to the LONG variable and no error is raised. Is there
any way this exception can be trapped ? Any info in this regard
will be much appreciated.

Also, it would kill distributed transactions running for longer than set time, not distributed transactions waiting for locked resources longer than set time. To kill distributed transaction waiting for a locked resource more then a set time (as OP requested) OP could set initialization parameter DISTRIBUTED_LOCK_TIMEOUT to desired value. Obviously, same timeout will apply to all distributed queries, unfortunately, DISTRIBUTED_LOCK_TIMEOUT is not dynamic parameter
SY.not sure what his issue is (maybe different from what we were facing), but our was not related to locking, it was basically hanging session. Remote server did not even see the session being connected yet it was hanging for hours on query across db-link. It was very rare - the session ran daily and hang maybe once a 6 months. In our case we just wanted to be informed that it hang, so production support could follow up on the issue.

Suggest me the solution

For the example in the tutorials to work, you need an application called an "echo server" to be running in the background. Now on UNIX boxes this is reasonably common, but on Windows it is not.
So you need to run a Echo Server for this to work, as it happens I've a small one:
import java.net.*;
import java.io.*;
public class EchoServer
    public static void main( final String argv[] ) throws IOException
         ServerSocket ss = new ServerSocket(7);
        System.out.println( "Waiting for client" );
         Socket s = ss.accept();
         InputStream is = s.getInputStream();
         OutputStream os = s.getOutputStream();
         int i = is.read();
        System.out.println( "Client Connected" );
         while( i != -1 )
              os.write( i );
              i = is.read();
              System.out.write( i );
         ss.close();
        System.out.println( "Shut Down Server" );
}Simply compile this, and run it in the background.

Need help for traping imported java bean exception

hi everyone
i have imported a java bean into my forms 9i using java importer utility which tries to rename a file on a give path(bean works fine when executed through sql client).
i have problem when called from when button pressed trigger, it throws me an ("FRM-40735 and ORA-105101 NON ORACLE EXCEPTION") error.
i have imported java.lang.exception class and constructed an exception handler to trap java exception in the trigger
as
EXCEPTION
     WHEN ORA_JAVA.JAVA_ERROR then
          message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
          --check for ORA-105101
     WHEN ORA_JAVA.EXCEPTION_THROWN THEN
          ex:= ORA_JAVA.LAST_EXCEPTION;
          message('Java Exception --: '||BIException.toString(ex));
          ORA_JAVA.CLEAR_EXCEPTION;
     WHEN OTHERS THEN
          message('error :'||SQLERRM);
when i imported java.lang.exception i did not find any wrapper pl/sql function or procedure declared to read or get the error messages except for the functions named "new" ,my exception handler failed.
so i tried with BIException which also fails to trap the error i have no idea about BIException and its usage with in forms ,Please do help me out with this issue ASAP.
thanks in advance

yash

Hi,
don't understand what the BIException is supposed to do in your code, can you try
     WHEN ORA_JAVA.EXCEPTION_THROWN then
     ex := ORA_JAVA.LAST_EXCEPTION;
     message('Exception: '||Exception_.toString(ex));
where Exception_ is the imported java.lang.Exception package.

SRM 7.0 Process-Controlled (BRF) Workflow -- Error message to Shopping Cart

I am modifying a BRF Expression used to calculate approval levels. During this calculation, I may run into error conditions (e.g. Currency tranlsation not found) that I want to display to the user (in the Shopping Cart).
I have tried raising the following exceptions:
/sapsrm/CX_WF_RULE_ERROR.
/sapsrm/CX_WF_RULE_ABORT.
Raising these exceptions do result in SLG1 log entries being written, but the User is not informed of the error (ie. at top of shopping cart where other messages display).
I can probably jump out of the Webdynrpo to read logs, but thought there MUST be some standard way of passing error conditions from the BRF, back to WF, and then back to the Webdynpro Window.
Anybody raise error messages back to the online user from Process-Controlled Workflow?
Thanks,
- Tim

Hi Saravanan,
I am actually modifying the Approval Limit Checks (for multi-currency translations) that you recently coded in Maryland. It can occur that errors occur in determining limits (new Currency translation I just added), or during the lookup of agents (ie user config is inconsistent).
In these cases, I can make the shopping cart Dump, by raising untrapped error messages, or assertions. However, I would like to raise exceptions that get trapped (such as the ones I identified in original post), and then make their way to the shopping cart.
Unless I am missing something, I don't think the WF BADIs, or BRF are gonna communicate errors back to the shopping cart, even though these components are called during cart creation and checks.
I realize that I can recode the Agent Determination BADIs, BRF calls, or even read BRF logs within BBP_DOC_CHECK_BADI. I mentioned this in my original posting as well.
Anyway, any help is appreciated.
Thanks,
- Tim

Status report from Procedure/functions

All,
I have procedures /functions in my database. I need to return a status value back to the call procedures/functions to report the sub_procedure/function executed successfully.
What is the status value if a procedure/function executed successfully? And what is the value for un_successful execution? Where I can get it from?
Thanks a lot!

This is really a design choice that you have to make in your application. PL/SQL stored procedures / functions do not return any implicit status codes on there own. In your PL/SQL code, you can check the SQLCODE built-in function for the status of the last SQL statement executed, but this is hardly the same thing (and really designed for use in exception handlers).
You may choose to design you applications such that every call must return a status value. In this case, the values used to represent success or failure are up to you (I might suggest 0 for success and the error code - which will be non-zero - for failure). You can either use functions which always return a number (probably not a good idea to place this limitation on your application); you might design all stored procedures to return an output parameter which indicates success or failure.
But, in general, your client code should be designed to correctly handle all Oracle exceptions - if no exception is raised, then success, else failure. And your PL/SQL should avoid bad practices like exception handlers which trap WHEN OTHERS and don't re-raise the exception.

How to create separate log files for each deployed web application in oc4j

Hi All,
I am using Windows2000, Oracle9iAS(OC4J). Say I have deployed 3 web applications onto this oc4j server. Then how to create 3 different log files so that I can see the log messages(System.out.println's) of each of these web appliations in a different log file.
Thanks and Regards,
Ravi.

Where do the messages printed via ServletContext.log() go? Is this configurable separately by web application? If so, you could at least replace your System.out.println() with sc.log() statements. For exceptions, you could trap them and log them since the log() method takes a throwable as well as a String.

Please Help Me Out of The Error

Hello Everyone,
I am executing the following Syntax to create a procedure which will spool all the data of my employee table and dumped into a Text file. The Procedure is creating successfully, but problem is when I am Executing the Procedure I am getting an error.
The Syntax I am using to create the Procedure is:
CREATE OR REPLACE PROCEDURE dump_emp
IS
file_handle UTL_FILE.FILE_TYPE;
BEGIN
file_handle := UTL_FILE.FOPEN('c:\file_dir\','dump.txt','w');
FOR emp_rec IN (SELECT * FROM MANOJIT.EMPLOYEES) LOOP
UTL_FILE.PUT_LINE(file_handle, emp_rec.emp_id || ',' || emp_rec.ename || ',' || emp_rec.department_id || ',' || emp_rec.salary);
END LOOP;
UTL_FILE.FCLOSE(file_handle);
END dump_emp;
The Error I am Getting when I Execute the Procedure is:
ERROR at line 1:
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at "SYS.UTL_FILE", line 98
ORA-06512: at "SYS.UTL_FILE", line 157
ORA-06512: at "SYS.DUMP_EMP", line 5
ORA-06512: at line 1
Please Help me in this matter.

One of the quirks of UTL_FILE is that its execptions are treated by Oracle as user defined - hence the cryptic message. In order to find which error you're getting you'll need to put in an EXCEPTION section and trap the UTL_FILE exceptions - see the docs for details.
I would guess that the problem you're getting is this: your database is on a server and you're trying to write to your client machine (i.e. your PC). You can't do this. PL/SQL is a server-side language and can only see the directories on the database machine. If you want to dump stuff to your local machine you have to use the SQL*Plus spool command, using DBMS_OUTPUT instead of UTL_FILE if you want complex assemblages.

RAC node Hung

Hi Friends,
Server info:
Windows 2003 server
Oracle 10.2.0.5, 2 Node RAC
We are having problem Hung Node 2 server due to Blue dump error. But in Oracle we are not getting any error on CRS & alertlogs. After restarted the server problem solved. How can we identify what could be the reason of server hang. We are not getting any error in Operating System side also. Is there any way to identify the problem of server hang after restarted server?
Thanks in advance.

OS side also having no logs generated except "*Blue Screen Trap (BugCheck, STOP: 0x0000FFFF (0x0000000000000000, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000))*" . As per my knowledge this is not a Node eviction problem. We are not able to find any node eviction log in Oracle logs.
See this note:

SORRY FOR MY ENGLISH

I'm not sure why you're using a WHEN OTHERS exception clause.
Trapping all errors and issuing a rather unhelpful "An error occurred" message is seldom very useful. Allowing any errors you don't specifically want to handle to propagate normally makes debugging much easier.

Problem executing SELECT statement due to st_spatial column type

I am using a CachedRowSet and cache.execute() will not run because it does not support the st_spatial column type. I have been told to use the column metadata to build a select statement of column names, and check the column's type before you add it to the select clause. But, I am unsure of what to do since I can't get column names without running a select statement first... I will attach some code for you to look at, but please give me suggestions!
try{
Class.forName("com.informix.jdbc.IfxDriver");
CachedRowSet cache = new CachedRowSet();
cache.setReadOnly(true);
cache.setUrl(dbname);
cache.setUsername(user);
cache.setPassword(password);
cache.setCommand("SELECT * FROM "+table);
try{
cache.execute();
}catch(Exception e){
out.print("Can't Display");
OTHER JSP CODE THAT WORKS WITH THE RESULTS FROM ABOVE
}catch(Exception exc){
out.println(exc.toString());
} // end try-catch

I honestly don't have a clue. I have no idea what the st_spatial data type is, or where it is defined, and as a result, I don't know why Java would be complaining about it. I do know that java.sql.ResultSet doesn't care about it (it would internally recognize it as a plain old object type via the getObject() method and you would have to cast it to st_spatial).
What I would check:
Is the Informix driver up to date?
Does the CachedRowSet class extend ResultSet or otherwise use it as an internal data structure? If so, does it properly create the ResultSetMetaData object and no exceptions are being trapped?
Otherwise... when copying data from the ResultSet object into its own internal data structure, does it correctly realize that the st_spatial column should NOT be copied into a String or a slot in a String array?
Does a quick and dirty command line version of your program properly use CachedRowSet to retrieve at least one record from your database?
Basically, put the JSP aside and just test the CachedRowSet to make sure it is working correctly. I have no idea what's in that class since it is not a Java standard class, so I can't really give you any additional suggestions.

Lock record problem.

Hi All. I use Firebird DB with WLS. In Firebird when no DataBase transaction parameters specified the default parameters is set. By default transaction isolation levels is "concurency, wait". It means that when 2 concurrent transations try to lock record (select ... from table for update), second transactoin waits while the first will be complete. I need exception in this case (nowait in transactoin parameters).
In Firebird JDBC driver there is a file with mapping to standart jdbc transaction isolation levels:
TRANSACTION_SERIALIZABLE=isc_tpb_consistency,isc_tpb_write,isc_tpb_wait
TRANSACTION_REPEATABLE_READ=isc_tpb_concurrency,isc_tpb_write,isc_tpb_wait
TRANSACTION_READ_COMMITTED=isc_tpb_read_committed,isc_tpb_rec_version,isc_tpb_write,isc_tpb_wait
I change wait to nowait in this file, bat i dont no where i can set transaction isolation level on weblogic server. How I can do this?

In the on-lock trigger, instead of Lock_record; you should write your own sql "select for update no wait".
Then I am not sure... either write your own exception clause to trap the ORA-00054, or trap the exception in the on-error trigger.

Exception cant aable trap.
