Hi Christian,
The background is a small bug in com.sap.nw.wpc.core.utils.Utils.getContentAsString where getInputStream is called on a KM resource (the correct forum for this question would have been portal-km), without closing the InputStream afterwards. Behind the scenes, getInputStream opens a JDBC connection which won't be closed afterwards.
So, if this still happens, it would be the best to open an OSS message to report this bug to SAP so that this can be fixed in the web page composer implementation. But on the other hand, this is now more than one year old - maybe this is already fixed. I cannot check, as I don't use WPC at the moment.
Best regards
Detlev

Hi,
Posting this error in metalink you could get nice directions...
I have the same problem, and looks fixed now...
Try review doc 420761.1
And what I do, was:
Stop dbconsole
start dbconsole (fails)
review logs generated and look this errors:
$ORACLE_HOME/<hostname>_<instance_name>/sysman/log
doing there a directory listing by date, "ls -ltr" the last file showed is the modified one, in my case was:

-rw-r----- 1 oracle oinstall 522694 Oct 27 19:34 emdb.nohup

And tail emdb.nohup gives you the instructions to fix the first one, in my case, solving the TZRegion was enough.
$ tail emdb.nohup
----- Tue Oct 27 19:19:05 2009::The agentTZRegion value in /oracle/product/102/db_1/dbserver.uadec.mx_siin/sysman/config/emd.properties is not in agreement with what agent thinks it should be.Please verify your environment to make sure that TZ setting has not changed since the last start of the agent.
If you modified the timezone setting in the environment, please stop the agent and exectute 'emctl resetTZ agent' and also execute the script 'mgmt_target.set_agent_tzrgn' to get the value propagated to repository -----
Hope this could help you.

Help Needed! java.lang.Exception: Unable to connect to server

I am trying to connect remotely to my office workstation and get the error "java.lang.Exception: Unable to connect to server". I have already upgraded to MountainLion, installed Java 7, and have also tried 3 different browsers (Safari, Firefox, Chrome) without success. I was able to login a few weeks ago and it has since stopped. My employer's IT support cannot understand how to help me and they're telling me I need to buy a PC.
Can someone help?

Check whether your connection pool and datasource are really
started. Also check you have the correct JDNI name, NOT name,
for your datasource.

Java.lang.exception: word is too big

Hi everybody!
I have a problem need your help. At present I have a server-client application, server running on Linux enviroment, client running on Window enviroment. After a period of time, there is a exception thrown to console: java.lang.Exception: word is too big, try to use less letter ..... And at that time, no more client can connect to client, however clients which connected to server from before still run as normal. Please help to fix this. Thank you very much

I can not upload the source code here because it's so big. Before I have never ever met this error. Nearly I have a new server linux machine, and I run my program on this machine, as a result I have had this problem. I say I can catch this exception means I try to trace it by in catch and throw but nothing can be catched. And "word is too big, try to use less letters..." is not mine. I saw it in console. At first, I don't know why client can not connect to server, so I try to find out it in console mode and as you know I find out this exception. If anybody have ever met this error. Please explain it to me and help me to resolve it. Thanks

Java.lang.Exception: No such metric - dbconsole error (RAC DB)

I'm running the database console (10.2.0.1) from one RAC node (2-node cluster), and the agent is running on the second node. WHen I try to load the cluster home page, I receive the following error "java.lang.Exception: No such metric" at the top of the page. The rest of the page looks correct.

Java.lang.Exception: Exception in sending Request :: null

hai folks
i down loaded oracle database 10g release 2 from oracle site. after successflly installing the oracle database i got the following java exception when logged on as sys/passcode as sysdba
java.lang.Exception: Exception in sending Request :: null
can any one help me in this regard since i installed oracle database number of times and ended up with same error .

connect to the instance using SQL plus, to make sure userid and password are working.
then from OS console check dbconsole status
emctl status dbconsole
emctl status agent
if dbconsole/agent is not running then start dbconsole--emctl start dbconsole
you can also start dbconsole from services tab under admin.

Java.lang.Exception

I am new to 10g DBA. Everything going well for me. But when I am trying to connect the host using the id and password I am getting the error message "*java.lang.Exception: IOException in sending Request :: Connection refused: connect*". Except this everything is OK in my OEM. Can anybody help me in this regard. I need some urgent help. Do I need install any other software or configuration?

First, try just quitting iTunes (you may want to restart your system) and try again.
If that doesn't fix the problem. click on your account name in the top right corner of the iTunes window. When a second window appears asking for your password, hit "logout" instead. Then click on the "login" in the top right corner again and type in your user name and password. Then try logging in again. If it still doesn't work, repeat the process two or three times and see if that will eventually clear the error (it did for other users who've had the same problem in the past).
Hope this helps.

: java.lang.Exception in 10 g

after succsfull installation of oracle 10 g when i connect to consol then thi serror comes plz can nay one help me
the error is as
error : java.lang.Exception: Exception in sending Request :: null
Regards

You mentioned Oracle 10g, but if you actually refer to the 10.2.0.1.0 (unpatched 10gR2) then most probably you are hitting a configuration issue that is solved by applying the latest 10.2.0.4.0 patchset. This has to do with the Time Zone used by the local agent.

Java.lang.Exception problem .. help needed

I have a class and i am trying to access a method of another class that is reading an object.
public void read(String filename) throws Exception {
String fn = filename;
ObjectInputStream out = null;
Object object = null;
try {
FileInputStream file = new FileInputStream(fn);
out = new ObjectInputStream(file);
object = out.readObject();
out.close();
} catch (java.io.IOException IOE) {
if (out != null)
try {
out.close();
} catch (Exception ex) {}
throw IOE;
When i am compiling the program it is giving me this error
unreported exception java.lang.Exception; must be caught or declared to be thrown
I'm quite new to java ... could you tell me how to catch this exception
its in this part
scoreTable.read("scores.txt");
Thanks

Try this :
    private void someMethod(){
        try{
            read("c:\\bank\\testobject.txt");
        }catch(IOException ex){
            ex.printStackTrace();
        }catch(ClassNotFoundException ex){
            ex.printStackTrace();
//        you can use the object here
    Object object;
    public void read(final String filename) throws IOException, ClassNotFoundException{
        ObjectInputStream out = null;
        object = null;
        try{
            out = new ObjectInputStream(new FileInputStream(filename));
            object = out.readObject();
        }finally{
            if( out != null ){
                out.close();
    }
