Agent Connection to Instance error in Oracle Database 11G EM

Hi
I am getting the following error message when logging into EM on Oracle 11G Database.
Failed to connect to database instance: ORA-12541: TNS:no listener (DBD ERROR: OCIServerAttach).
Users can connect to the database no problem and it shows the Database Instance down, Agent Connection to Instance failed. The General tab shows green and the database is up.
I have checked the emctl status and lsnrctl commands and the listener is up and servicing the database. I checked the ORACLE_SID environment (in Windows Server 2003) and this is correct.
I have recently changed the passwords for SYSMAN and DBNSMP which were due to expire and since then the EM console has not loaded correctly.
As I said the database is up and can service users through their application.
Any help would be appreciated.
Respect.

Hi
The listener is up and is handling the database and users are connecting succesfully. I think it is more to do with the Enterprise Manager.
Can anyone give me some further info to troubleshoot?
Regards
Spencer

Note that this forum is for XE Beta, not EE.
Can you connect from some other client tool, such as sqlplus?
There's a {forum:id=178} forum that may be more suitable, if basic connectivity outside php works (i.e. issue is only php specific).

Find the hostname and service name of the database and use those values in the ORA_CON_DB constant.
Use 'lsnrctl status' on the database host to find the service name.
If you use a "tns" alias, you may need to create a tnsnames.ora file where PHP can access it.
Set the environment variable TNS_ADMIN (on Linux) to the directory containing the file.
See the section "Oracle Database Name Connection Identifiers" p 102 of the free book

ORA-12505: Database Instance and Agent Connection to Instance will not work

Hi,
I have the following error: in Oracle 10g I try to connect to OEM and the listener is up but the Database Instance and Agent Connection to Instance are down. When I attempt to restart the instance, OEM will just hang indefinitely. I have used tnsping and the results are OK. Is that descriptive enough? What can I do to fix this?
regards,
John

I changed the SID because I was mistaken and thought of the oracle database name. I have corrected the ORACLE_SID to that given in my tnsnames.ora file which I post here:
ORACLE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Lasirius-laptop)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = oracle)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
These are the default settings that were made on installation. I have been working with this installation for 2 months, and it just suddenly stopped working. I have changed no other settings apart from the mistaken ORACLE_SID environment variable in this post, which has now been changed to PLSExtProc. Here is my init.ora:

Database Instance down Agent Connection to Instance down

Hi
I have installed Oracle 10g on Windows XP SP2 and i m new to Oracle 10g.
In Oracle Enterprise manager I have
1. database instance Down
2. Listener is UP
3. Agent Connection to Instance is Down and giving an error
ORA-12505: TNS:listener does not currently know of SID given in connect scriptor (DBD ERROR: OCIServerAttach)
I m unable to connect through sql*plus command window it gives protocol adapter error
But I am able to connect through windows command prompt
but each time when i connect through it i have to set sid by command
set ORACLE_SID=orcl10g
I m also not able to use isqlplus
what should i do
pleease help me

I tried ur suggestion and the command i typed are here
C:\Documents and Settings\tony>sqlplus /nolog

but problem is same database instance is down Agent Connection to Instance is down and listener is up.

Agent Connection to Instance Unavailable

Win2k3 64 bit
Oracle Database 10g Release 10.2.0.5.0 - 64bit Production
I brought up a new 10.2.0.5.0 db on Win2k3 64 bit server. Everything is working fine, at least it seems so. This server has been running for 2 months now and this issue kept coming up in the last 2 months.
Database Instance status is Open
Listener status is Up
General status is Up
Agent Connection to Instance is Unavailable.
Users SYSMAN and DBSNMP are OPEN.
This will be the 3rd time in the last 2 months if I rebuild EMCA again.
Is anyone else besides me experiencing this issue? Why is this happening and how do I fix it permanently?

1.Post the output of :
SQL> select global_name from global_name;
SQL> show parameter db_domain;
2.lsnrctl service
3.lsnrctl status
4.Did you change the hostname?
5.Is timezon of agent and console the same?
6.In the file $AGENT_HOME/sysman/config/emd.properties, make sure the following parameters are correct. Obtain the values from $OMS_HOME/sysman/config/emd.properties
1. REPOSITORY_URL
2. emdWalletSrcUrl
3. emdWalletDest (ensure that this destination is present on your management server).
7.If you're using Data Guard in 11g for primary/standby configuration, you may want to check the Data Guard configuration status. With this type of error, it's usually caused by the database parameter setting for log archive that differs with the Data Guard config for log transport and apply. For example, if the local archive log destination on the primary is pointing to the standby site instead of local archive directory (or local flash_recovery_area), The GC will generate this error and blank out the options for database instance in GC.
I am just pasting the above texts from different forum link when I just said "Agent Connection to Instance Unavailable" to google.

Oracle Database 11g Installation Issue: ORA-12560:TNS: protocol adapter error.

Folks,
Hello. Initially, my Windows XP host name is "localhost" and IP address 127.0.0.1.
I installed Oracle Database 11g with Windows XP successfully and all Database clients work with Database instance correctly.
For some reasons, I uninstalled the entire Database Server and delete the entire installation directory /oracle.
I configured Windows XP IP address into 192.168.196.101 in order to ping other machines.
For my need, I installed Oracle Database 11g with Windows XP again. On step 7 of 8: Oracle Database Configuration Assistant, I got this error:
ORA-12560:TNS: protocol adapter error.
I click "Password Management" button, there are no rows in this Windows (no username, no lock accounts).
I check listener as below:
C:\>lsnrctl
LSNRCTL>start
Its output: listener name LISTENER has already been started.
LSNRCTL>status
Its output: ......Service DB1 has 1 instance. Instance DB1 status ready. The command completed successfully.
I check \Oracle\cfgtoollogs\dbca\DB1\trace file, the entry is :
listen[0]=LISTENER address=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(port=1522))
I also check \oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\SAMPLE\tnsnames.ora file and listener.ora file, the entries are the same as below
HOST=localhost port=1522
I think HOST=localhost and port=1522 is the cause of the error ORA-12560 because Windows XP has been configured into HOST=192.168.196.101.
But I don't understand how to solve this issue.
Can any folk tell me how to solve this issue ? need to cancel the installation on step 7 of 8 and install it again ?
Thanks.

Folks,
Hello. Oracle Database 11g Installation Wizard is on step 7 of 8. I don't cancel the Wizard. I am not sure whether there is effect or not. listener.ora is not removed. I have been waiting for a while after stop listener. I run the 3 commands again and copy the result as below:

Agent Connection to Instance - Failed ORA-12541

Hi folks, I recently changed the SID (but not name) of my database. Everything has been working great, but I get the following error message in OEM after it's been running for about 10 minutes:
Agent Connection to Instance
Status Failed
Details Failed to connect to database instance: ORA-12541: TNS:no listener (DBD ERROR: OCIServerAttach).
Since everything else is running fine (everything else in OEM is working fine, network connections via SQL Developer, Toad, JDBC, I'm not sure where to look.
I also have a second server running (on which I haven't changed the SID) to compare to. Outputs of lsnrctl services, the tnsnames.ora file, and everything else seems to line up.
I'd be happy to post anything that might be useful, thanks very much!

Hello,
recently I was hitting the same problem:
Listener Status: Up
Agent Connection to Instance Status: Failed
Details Failed to connect to database instance: ORA-12541: TNS:no listener (DBD ERROR: OCIServerAttach).
It turns out that the message is misleading and the problem lies in the locked dbsnmp account. I resolved that through
Grid Control / Targets / Search List / (Select DB with problems) -> Configure
where it showed the following error:
"java.sql.SQLException: ORA-28000: the account is locked The Connect Descriptor was (description=(address=(host=xx)(protocol=tcp)(port=xxxx))(connect_data=(service_name=xx)(instance_name=xx)(UR=A)))
Change dbsnmp Password - The error message shown above indicates that the agent is unable to monitor this database because the agent cannot logon. To correct this, the Monitor Password needs to match the corresponding database password for dbsnmp. To change both the dbsnmp database password and the Monitor Password, click the Change dbsnmp Pasword button. This operation will also unlock the dbsnmp user."
It is possible to change the password from that dialog what I did. It is working fine now.
I do not know if the problem lies in accout locked or wrong password after all, but repeating the configuration resolved the case.
Greetings

Unable to connect to the informatica repository on oracle database 11g

hi all,
i have installed OBI Apps 7.9.6.0 with informatica 8.6.0 and no hotfix.
Now the problem is , when i create a repository service i get the error
" The service did not start due to the following error: *Unable to connect to the repository Oracle_BI_DW_Base on database* . " here Oracle_BI_DW_Base is also the name of my .rep repository that came with OBI APPS installation.
i have oracle database 11g installed and also created respective user for repository of informatica.
what should i do in this case??
plz help

Good Morning.
I had the same problem and I had the same IE 6, the problem was the translation between the IE6 from http and https, to solve it you just need to open your url typing
https:url:port, do no forget to put the s after the http, with this my problem was solved.
best regards.

Hyperion errors after installing Oracle Database 11G

Hello,
The company I work for has a bunch of Oracle databases available, two which I connect to (use to connect to). I have multiple applications that I use to connect to these databases, Hyperion Interactive Reporting Studio 9.3.1 being one of them. I'm using Windows XP as my client.
I made the mistake of installing Oracle Database 11G Express Edition and now I cannot connect to any of the database using my applications, but I can connect to the same databases using SQL Developer. When I try connectiing using Hyperion, I get "SQL NATIVE ERROR [12504] SQL MESSAGE [[INTERSOLV][ODBC ORACLE 8 DRIVER][ORACLE 8][ORA-12504; TNS LISTERNER WAS NOT GIVEN THE SERVICE_NAME IN CONNECT DATA".
When connectiing using other company applications, which use the same database, i get "IM006: [INTERSOLV][ODBC ORACLE 8 DRIVER] DRIVERS SQLSETCONNECTATTRFAILED. UNABLE TO CONNECT TO DATABASE. CHECK USER NAME AND PASSWORD AND TRY AGAIN"
I'm assuming that I updated a driver or registry setting and I need to know how to reverse . I also copied a tnsnames and listerner from an associates computer and placed it in the same location on my computer, but this has not helped at all, even after rebooting the computer.
I even double checked and logged onto anothe computer and I can connect to the database using these same applications, so I definetly messed something up locally on my computer.
Any help is appreciated. Joe.

Probably you could solve odbc driver issues by removing the PATH entry from XE installation.
It looks something like:
Path=C:\oracle\oraclexe\app\oracle\product\11.2.0\server\bin;<remaining paths>
In system variabels settings, edit PATH to remove the "oraclexe" path and semicolon, leaving only <remaining paths>.
However, removing it will likely have an affect on XE usage. But that may be preferred over other apps working.

Forms 6i don't connect to Oracle Database 11g.

Hi people, I'm having a great problem, first I have a old server runing Red Hat with oracle 10g XE, this oracle XE is almost full, so I need to install Oracle Database 11g XE to get more space in another server, this another server is runing windows server 2003, I did it tow time in tow diferent server, a restore for migration is all right, the problem is when I try to connect forms6i to the database 11g XE, forms only closed without no error message...
Some one has some help?
Regards,

Also take a peek at some of the compatibility settings within 11g XE. You can get it to act like 10g XE regarding password caps vs lower case and such. We've been able to get a client/server forms/reports app (patch 18) to connect to and run just fine to 11g XE.
