Database Instance & listener

Hi,
currently i want to connect an ETL to an ORACLE 10g database. But i need to start a listener on the port 1521.
I tried with enterprise manager by a webbrowser but i had any success.
Somebody knows how to start the listener without use Enterprise Manager (by using sqlplus for example)?

OEM 10g DBControl: no information in Database Instance. Listener and Agent

Hi,
we hat a Database Crash, after recovering the Database the OEM is not working completely.
There are no informations about Database Instance, Listener and Agent.

If you recovered only the database ensure that
Database Name and Instance Name remains unchanged.
Listener name and ports is the same
Ensure they all services can start successfully. If not, recreate the services.
If you recovered any other thing other than the database, ensure that you followed the correct recovery procedure for both the database and directory structures
e.g
Directory names and structures are recreated as before Crash
Oracle and Agent Homes remain the same as before crash
IP Address and Ports remain unchanged
Then restart both the database and db control
In short, the important thing is to keep all all before crash especially for DB Control to work immeiodiately.

Problem: Enterprise Manager is not able to connect to the database instance

Hello,
I've got problem with EM. When I try to connect to it I get the following error:
Enterprise Manager is not able to connect to the database instance. The state of the components are listed below.
Database Instance, Listener and Agent are all green.
Few more information:
OS: Win7 64 bit
-installed loopback adapter. I can ping my computer name (J-PC) without problem and it pings back 10.10.10.10 address.
-I have set the ORACLE_HOME and ORACLE_SID env variables
-I can login to sqlplus with sysman account
-emctl status dbconsole shows that the EM 11g is running
I've been struggling for some time trying to get EM running as it should, but no luck so far.
If you need any more info, do ask. Tnx.

Listener (and database instance) does not starts up automatically: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

Hi at all.... I'm a newbie with database oracle.,
I have the follow problem:
I installed Oracle Database 11g R2 XE on my guest operating system CentOS 6.5.
I have changed the hostname in my SO CentOS (where is installed oracle 11g R2 XE) after installation was completed successfully.
-) Before and during installation the hostname was localhost.
-) After installation I changed the hostname in VMCentOS
From the moment I changed the hostname, nothing starts up automatically. In particular, the listener and the database instance does not starts up automatically.
When I starts up the listener manually and I try to connect to database instance with SQLPLUS i get this error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
I think that the problem is due to the changed hostname because I, for testing and debugging purpose, re-installed a new OS CentOS virtual machine, re-installed oracle database 11g and I have not got that problem. The database instance and the listener starts up automatically!
Can any one tell me if maybe the problem is related to the hostname changed? ... and Why?
P.S.: After changed the hostname I have also modified the listener.ora and the tnsnames.ora by modifying the HOST with the correct hostname.

Failed to connect to database instance: ORA-12541: TNS:no listener

Hello -
This is the error in grid alert:
Failed to connect to database instance: ORA-12541: TNS:no listener (DBD ERROR: OCIServerAttach).
But the test of connection string in database configure screen is successful. tnsping works too.
Grid version: 11.2.0.1.0, no patches.
Target database version: 10.2.0.2
Connect string: (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST = s08) (PORT = 1528))) (CONNECT_DATA = (SID = S08) (GLOBAL_NAME = S08.WORLD)))
Any ideas?

OK.. Are you testing the connectivity from "Preferred Credentials " setting page?
Try to configure target from
Targets-->databases--> then select your database and click on "configure" button.
Enter all the details and press "Test Connection" button once it shows that connection is successful go to next page and finally save the setting.
Let me know how it goes....

Dear all,
I have trouble to connect em console to database instance. My database is 11.2.0.3 and before this I did the patching from version 11.2.0.1, and now i cannot get fully functionality of em console.
error is:
Enterprise Manager is not able to connect to the database instance. The state of the components are listed below.
It shows that agent is connected, database and listener is up.
I did recreation, dropping and recreating with emca, but no success.
Did anyone have similar problems with em console?
Regards,

You need to first of all, Connect to the Database as SYSDBA (because your were not connected), then start the database (because it is not started).
If you already used the username and password in the command prompt and you are sure that the database is already stared, then you need to set the ORACLE_SID before you open SQLPlus. This is because if SQLPlus does not know the SID you are connecting to, it simply thinks it is not up or has no service hence the message "Connected to an idle instance".

Enterprise manager is not able to connect to database instance

Hi
I am having a problem with Oracle EM. I would appreciate very much if anyone can help me.
I installed Oracle on XP which runs on virtual pc on XP as well. Everything is fine, I can connect to database with sqlplus, and there were no errors during installation.
But the problem is that, when I try to connect to database with EM, it says:
Enterprise manager is not able to connect to database instance . The state of the components are listed below.
Can anoyone help me?

Ent. Manager is not able to connect to the database instance. ORA-12541

Hi
I have installed and configured Oracle 10.2.0.1 on a Microsoft Cluster with Windows 2003 Server.
Database instance and listener are running OK on both cluster nodes.
On one of the nodes (pwmssrv1) I configured Enterprise Manager to monitor and control the database.
At the beginning it worked fine, but after making a reboot on this server the Enterprise Manager cannot see the database instance and listener anymore.
I already recreated/reinstalled EM and the problem persists.
When I try to access the Oracle EM I get the errors (it do not show the login page):
Database Instance

Can someone help me on this problem.
Thanks in advance.

You need to do some troubleshooting to find exact issue...
Here are some metalink notes,

Now when I try to open Enterprise Manager I am getting following message:

So when I look to log in emagent.trc i see this:

What I need to do, to resolve this problem?

Thanks for answering. This my logs files:

Enterprice manager is not able to connect to the database instance

hello,
I have problem with EM. I have some databases, and I worked with Enterprice Manager on this databases. First DB when I have repository is ok and EM always connect with this, but I worked on another DB some time and was ok, but three days ago when I start EM I get message 'Enterprice Manager is not able to connect to the database instance'. When I couldn't resolve this problem, I make new DB and this worked two days ok, and today I get this same message. I don't make any changes in listener and tns files.
any idea?

Not able to connect linux database instance in another machine

Hi,
I have installed oracle 10g database server in Linux, and i created one database instance. and i have added tns entry and listener entry.
I am to connect the database on that machine. but not in different machine. i am able to access/ping linux machine in another machine also.
while creating tns entry for linux database instance in another machine using "netca" i am getting this error.
Connecting...ORA-12560: TNS:protocol adapter error
The test did not succeed.
Some of the information you provided may be incorrect.
Click Back to review the information provided for net service name, or Change Login to change username.
I verified listener and tns entry ( i think for this listener configuration is enough) also. and database is up.
If anybody knows why i am not able to connect linux database in another machine. is there any network configurations other than listener configuration.
Thanks in advance.

yes i tried to connect with ORACLE_SID, its successful. and using tnsname like you said.
Instead of using netca to create the tnsnames.ora entry on the second server, copy the tnsnames.ora entry from the DB server. Then use tnsping to test connection :-i done above but not able to ping the tns name, i am getting this error.

Problem in accessing second database instance on same host (ORA-12514)

Hi,
I had a database ICMDB installed on my machine. After that i created a second database instance (Service name: BI_APPS) using DBCA on the same machine. Using NETCA i also created a new listener OracleOraDb11g_home1TNSListenerBI_APPS_LISTENER on port 1522 on my machine. Then i configured this listener to listen for connections to service BI_APPS by adding the following to my tnsnames.ora:
BI_APPS_LISTENER =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.109)(PORT = 1522))
Then i changed the port in my tns entry for BI_APPS to 1522 as follows:
BI_APPS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.109)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = BI_APPS)
I then restarted the following services:
OracleOraDb11g_home1TNSListener
OracleServiceBIAPPS
OracleOraDb11g_home1TNSListenerBI_APPS_LISTENER
After this, when i try to access my first DB ICMDB via toad, the connection is successful. However, when i try to access the service BI_APPS i get the following error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
What am i doing wrong? Here is the content of my files:

Hi Ed,
I understand your point, however whenever i have tried to use the same listener to access my second instance, this is the error i have always received:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
That does not indicate you need a second listener.
And, after deleting the listener.ora file ,if i try the the command lsnrctl start, i get the error:
ORA-12560: TNS:protocol adapter error
Hence i restored the files. What do i do?
I've never experienced a 12560 trying to start a listener. I'll need to see if I can create a test system on Windows and try to recreate. Will be a good subject for my blog, that has been too long with no new content.
Since this is windows, I'd first check that the Windows service for the listenr is started.
Whatever, multiple listeners is NOT the solution.
