Agent Error? IOException in sending Request :: Connection refused: connect

For the past couple of days, I have been running into the "IOException in sending Request :: Connection refused: connect" error. I am running 10.2.01 on Windows 2003R2.
Along with this error, the DB Control shows agent unreachable.
Is there anything that anyone knows that may have caused this issue?
Thank You in advance,
Jeff

Jhep,
Have you changed the timezone settings on the database server? Check emdctl.trc and see what it says. In the meanwhile, (a) stop dbconsole service, (b) execute emctl resetTZ agent and (c) restart dbconsole service.
Kindly should refer to the following Metalink Notes for a possible workaround:
bq. Metalink Note ID: 362888.1 "Startup Agent: EM Agent will not start due to Timezone mismatch (Daylight \\ Savings changes for Australia)" \\ Metalink Note ID: 409121.1 "Startup Agent: Agent Fails to Start due to Incorrect Timezone File Used as \\ Pointed by ORA_TZFILE" \\ Metalink Note ID: 388280.1 "Startup Agent: ORA-20233: Invalid agent name when running \\ mgmt_target.set_agent_tzrgn procedure in repository"
Lastly, see if any of the following post(s) are of any assistance to you:
bq. Oracle 10g EM DB console Host Preferred Credentials for Windows \\ Oracle 10g EM DB console Host Preferred Credentials for Windows \\ New Error -- Since DST 2007 \\ New Error -- Since DST 2007 \\ DST Patching for Grid Control Release 2 \\ Re: DST Patching for Grid Control Release 2
Hope this resolves the issue.

REM Set environment variables ORACLE_HOME and ORACLE_SID in Windows System properties.
REM Open a Command Prompt window. Enter:
emctl stop agent
REM Identify an entry from supportedtzs.lst with an offset that matches the one in emdctl.trc
REM Edit emd.properties file replacing the agentTZRegion value with the one found in supportedtzs.lst.

Hi All,
I need some help on this issue.
I followed MOS Doc 259387.1 to reset dbsnmp password because its password is unknown.
The error is

Thanks in advance.

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

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.

OEM 10.2.0.3 Error" java.lang.Exception

Hello,
Does anyone have an idea of why I would receive error "java.lang.Exception: IOException in sending Request :: Connection refused" when I log into OEM Database Control???
Thanks,
Daniel

Thank you Chris... What exactly am I looking for here... I am new to the database that I am supporting and after reviewing the log files, the error began back in 2007-11-30. "IOExecption in sending request :: Connection refused". Also, I see error "Click Patching Setup to set required parameters".
Thanks!

Java.lang.Exception error?? (10gR2 EM)

I am using 10gR2 10.2.0.1 EM and have recently applied the upgrade patch 10.2.0.3 and the latest CPU.
When I login EM and try to get to the "Home" tab from performance/administration/Maintenance,
there is an error message:
java.lang.Exception: IOException in sending Request :: Connection refused: connect
However, I can click on the buttons in performance/administration/Maintenance and get response. The fact is, the EM failed to display any stuff after like 1 min.
Could I know what the problem is?
Thank you very much.

check the listener config

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: Exception in sending Request :: null on Windows7 64bit

Dear All,
I have installed Oracle 10g 32-bit on Windows 7 64-bit Ultimate Edition. After setting ORACLE_HOME and ORACLE_SID environment variables.
Oracle connected to sqlplus fine. But when starting Enterprise Manager in browser following error displayed.
The Enterprise Manager takes the SYS logon (as sysdba) quite happily and then it states:
Error
java.lang.Exception: Exception in sending Request :: null
Status Status Pending
Status Pending Since Unavailable
Last Known State
Please help anyone. This is so urgent.
Regards,
Rizi -DBA

I have resolved this issue myself. Basically problem is due to TimeZone mismatch of Oracle database and Window or OS.
Following are the steps to resolve the issue:-
On DOS prompt issue following commands.
1. emctl stop dbconsole
2. Following file contains valid supported TimeZones and select according to your region:-
e.g. Asia/Karachi
$ORACLE_HOME/sysman/admin/supportedtzs
3. Now open following file:-
$ORACLE_HOME/computername_SID/sysman/config/emd.properties
At the end of this file add:-
agentTZRegion=Asia/Karachi
4. emctl start dbconsole
5. Open browser and logged in Enterprise Manager using sys/password as sysdba.
Click on Pending Status and logged in again, Now you will successfully use Enterprise Manager.
Anyways, Thanks for your effort.

EM 10g : java.lang.Exception: Exception in sending Request :: null

I have installed 2 db on 10.2.0.1.0. The first one is running fine and easily manageable via Enterprise Manager. When I open EM on the second db I receive "java.lang.Exception: Exception in sending Request :: null" with no further explanation. When I try startup/shutdown, I get "Couldnot contact the agent. Verify that the url for the agent is null". However the db service and the DB console are up and running. I can connect via SQL*plus to manage my DB.
From a java application the connection fails with "java.sql.SQLException: Io exception: The Network Adapter could not establish the connection"
listener.ora is as follow:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\OraHome_1)
(PROGRAM = extproc) ) )
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2))
(ADDRESS = (PROTOCOL = TCP)(HOST = MyHost)(PORT = 1512) ) ) )
TSANAMES is as follow:
26ALER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = MyHost)(PORT = 1512))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = 26aler) ) )
LISTENER_26ALER =
(ADDRESS = (PROTOCOL = TCP)(HOST = MyHost)(PORT = 1512))
LISTENER_ORCL1020 =
(ADDRESS = (PROTOCOL = TCP)(HOST = MyHost)(PORT = 1512))
ORCL1020 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = MyHost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl1020) ) )
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO) ) )
Any clue what could be wrong?
The console servier is running as stated here:
starting Oracle Enterprise Manager 10g Database Control ...The OracleDBConsole26
aler service is starting................
the OracleDBConsole26aler service was started successfully.
Edited by: user730614 on Oct 27, 2008 8:27 PM

I have same issue when i upgraded the database from 9i to 10g...some articales point that the issue is related to the timeZone settings..
I hope some one here could explain what it is and how to solve it... thank you
