It would appear that your archive location is full. If it is full, then try to get some more free space there by either deleting the old archives or specifying a different location.
I don't see any mention of a flash recovery area in the log message, but you may also want to confirm that you have reached your space allocated to the FRA.

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....

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:

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.

Failed to connect to database instance: ORA-02002: error writing to audit_t

ORA-15081: failed to submit an I/O operation to a disk
Documentation on error says.........
ORA-02002: error while writing to audit trail
Cause: The auditing facility is unable to write to the AUDIT_TRAIL table. If this error occurs, SQL statements that are currently being audited may also fail. This error will occur if the SYSTEM tablespace runs out of disk space.
Action: Add space to the SYSTEM tablespace or delete rows from the AUDIT_TRAIL table. If these operations fail or do not eliminate the problem, shut down and restart Oracle with auditing disabled. This is done by setting the initialization parameter AUDIT_TRAIL to FALSE.
How should I check the system tablespaces ...I'm getting the error....and moreover they are autoextendible....Any idea about the issue

You can check the space available in any tablespace with a query from dba_free_space;
Give serious consideration to moving AUD$ out of the system tablespace. Theoretically you can not do this prior to database 11.1.0.7 (where you can use the built-in package DBMS_AUDIT_MGMT.MOVE_DBAUDIT_TABLES). But if you open an SR at metalink they will instruct you to do it manually which keeps everything legal and supported.
http://www.morganslibrary.org/reference/dbms_audit_mgmt.html
Also look into using resumable transactions (DBMS_RESUMABLE) to keep these things from happening in the future.

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):

10g RAC database: instances fail after a few days...

Im afraid I'm new to Oracle, so assume total ignorance when replying!
We have two servers, db1 and db2 running Oracle under Windows 2K3 web edition [SP1].
Both have a shared Direct Attached Storage disk, over a Scsi fibre connection.
The database is set up using instructions found online for RAC.
Either instance will stop, and the other will take over, after a few days. The problem is, we aren't using the database yet. [There isn't a problem with it, the development people have checked that they can use the database.]
The two errors [found using the EM console] which seem to be relevant are:
'Metrics "Database Time Spent Waiting (%)" is at 100 for event class "other"'
and 'Failed to connect to database instance ... TNS no listener'.
[Which is obvioulsly the failure]
I have scoured the web, and the rather dense reference books for Oracle I have access to, and to no avail.
Another contributing factor is the 'WMI Performance Adaptor' stops and starts on both machines every thirty seconds.
Any response/guidlines/advise would be greatly appreciated.
Apologies if I have started this thread in the wrong place!

Failed to connect to database ONLY at the first time

Hi all, I installed Discoverer 10g version and I'm using an Application User to connect to the server where's the Db is installed.
Every time I try to connect to the server with Discoverer Viewer or Desktop I have a curious behavior....
ALWAYS but ONLY the first time I try to connect I have the following error :
- Failed to connect to database - Unable to connect to Oracle Applications database: invalid username/password.
If I try to re-connect again the second time it works perfectly !!....so, I think, there's nothing related with my .dbc file.
I tried also to write the ':' at the end of the user name....but it didn't work.
Into the pref.txt file doesn't exist a parameter like DefaultUserTypeIsApps to set....
Anybody have had the same "strange" behavior and found a solution or workaround ?
Thanks in advance
Alex

Thanks for your answers first of all !
At the end I found the solution looking at the Note:307167.1 on Metalink:
Discoverer Plus 10.1.2 Fails with ORA-1017 Error On First Login Attempt Then Works On Second Attempt
This note is very useful but into the solution the point 3 is not correct !
3. Modify the servername parameter to indicate the fully qualified servername.domain
Example:
An httpd.conf setting of: ServerName my_servername.mydomain.com should match a Discoverer Plus URL like http://my_servername.mydomain.com:7778/discoverer/plus
I had this problem both with Viewer and Plus...so instead to change the server name parameter (into the Apache/Apache/conf/httpd.conf file) with my complete URL (http://gnvdev.ote.gr:7779/discoverer/plus), I just write my right server name:
Example
After the installation of the Discoverer 1og server, into the httpd.conf file it was written automatyically: ServerName gnvdev
I just modified in ServerName gnvdev.ote.gr and both Viewer and Plus started to work perfectly at the first time.
I hope that this hint will be useful for you and others in the Discoverer forum !!!
Best Regards
Alex
