TNS- 12545: no listener

i cant log in to my database, it gave me this error "TNS 12545 - no listener"
i checked the listener.ora and the tnsname.ora and they are correct..
i run:
# /ORACLE_HOME/bin/tnslsnr start ---> it is ok
# /ORACLE_HOME/bin/lsnrctl start it gave me an error:
TNS-12545 , TNS-12560 and TNS-00515
my listener.ora is:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = mydb)
(ORACLE_HOME = /xxx/xxx)
(SID_NAME = mydb)
LISTENER =

At least your ORACLE_HOME environment variable (maybe others ?) is not set. See this example from my test machine :

Hi,
a different point: make sure the (host = ) part of your ADDRESS_LIST is correct, it seems the listener tries to bind to a host/port combination that does not exist. Don't use localhost there or nobody will be able to connect to the database which is probably not what you what.

Martin

LISTENER: TNS-12545 ... No such file or directory - to be continued...

Sorry to double the same problem but it turned out that the issue still exists...
This is a continuation of this thread:
LISTENER: TNS-12545 ... No such file or directory
sorry, SELinux was has been working in PERMISSIVE mode, so that messages in /var/messages are not dangerous,
I thought my problem was resolved, because suddenly I could connect to a database, but today my sysadmin told me that SELinux was in permissive mode and that it has no influence on my problem...
Where else to search ?

as is stated in http://www.ora600.be/node/1411 :
Step 03
Check the listener service handle in block state: Issue lsnrctl services and see status information under the database service name. Check the state and see if the state is in blocked.
$lsnrctl status
Service "san" has 2 instance(s).
Instance "san", status UNKNOWN, has 1 handler(s) for this service...
Handler(s):
"DEDICATED" established:10 refused:4276
LOCAL SERVER
Instance "san", status READY, has 1 handler(s) for this service...
Handler(s):
"DEDICATED" established:138 refused:0 state:ready
LOCAL SERVER
If state is in blocked state then connection is not possible. The state of a handler can be in blocked state if,
1)Database in startup or shutdown process.
or,
2)The initialization parameter value of PROCESSES has reached it's limit.
In this case if you are in dedicated server mode you need to increase static processes parameter.
If you are in shared server mode and your connection is refused based on limits then increase the dispatcher parameter.
Step 04 Check if local connection as sysdba is successful: Check whether you can connect to database as sys user as sysdba. If local connection is ok then check database open_state. Also check v$instance view fields like status, active_state, blocked fields.
Step 05 Check the Processes is reached it's limit:
If local connection sys as sysdba is successful then query from v$resource_limit and see the processes parameter.
SQL> select * from v$resource_limit where resource_name='processes';
RESOURCE_NAME CURRENT_UTILIZATION MAX_UTILIZATION INITIAL_AL LIMIT_VALU
processes 120 150 150 150
If max_utilization reached the limit value then consider to increase the static processes parameter.

Hi,
Did you check whether the windows service for listener is up and running? if not please start it, by typing "services.msc" in run window and start the service. Then check whether you have listener.ora file in $ORACLE_HOME/network/admin and also post listener.ora contents.
Regards,

TNS-01151: Missing listener name - APPS_VIS

Hi,
We completed the installation of E-BIZ Database and Application onto separate VMs via Oracle's eDelivery templates. Both new VMs are up and running per the OVM Manager.
However, we are not able to connect to the eBusiness Application. Per the e-Business Suite Rapid Install guide, we should be able to verify installation by accessing:
http://<host name>.<domain name>:<HTTP port>/OA_HTML/AppsLogin
We receive a HTTP Internal Error when trying to access this.
Numerous verification steps have been performed including:
- Testing network connectivity (ping) between APP VM and DB VM using the hostname
- Checking that the tnslsnr on DB VM is listening on port 1521, which is what was also configured for APP VM
- Checking that the httpd on APP VM is listening on port 8000
I am unable to run lsnrctl to check the status - how should my profile be set to be able to run this as I receive: lsnrctl: error while loading shared libraries: libclntsh.so.10.1: cannot open shared object file: No such file or directory
I have also included adalnctl.txt log from the E-BIZ Application Server. I'm not sure whether the LISTENER.ORA on the APP or DB server should be updated. And if so what should it be updated with?

Just a follow-up to this thread. We have now been able to start and successfully login to the e-Business Suite.
The source of the problem was in the installation of the e-Business Suite (via template) - it previously never completed successfully due to:
1) DNS - No DNS has been setup with the new virtual hosts as this is simply a prototyping activity. We found that it initiates connection with DB host during installation and will not complete successfully if one is not found. Furthermore, the /etc/hosts file is wiped of existing entries and replaced just with the host of the e-Business application server everytime ebiz_1211_reconfig.sh is run. Workaround is to login to the host during the reconfiguration and update the /etc/hosts file just after it instantiates the static IP address
2) Apps Password - The application could not startup as it was connecting to the database with a locked out user account. It uses the 'app' user to login to the DB - hence the apps password set during the e-Business application installation must correlate with the app user on the database - in this instance we kept it as apps/apps
After resolving the above issues we are able to connect through the web URL to e-Business Suite.
My next question is, assuming our database instance is called 'VIS', why is adalnctl trying to look for APPS_VIS in the listener.ora? I read
Thanks.

WINDOWS 용 SQL*NET 사용 시 TNS-12545

제품 : SQL*NET
작성날짜 : 1995-11-10
WINDOWS 용 SQL*NET 사용 시 TNS-12545
====================================
에러 TNS-12545 "TNS:name lookup failure"는 TCP/IP 프로토콜 어댑터를 가진
SQL*NET V2를 통해 툴에서 연결하려는데 TCP/IP 프로토콜 어댑터가 TNSNAMES.ORA
파일의 ADDRESS 부분에 제공된 호스트 이름을 분석할 수 없을 때 발생합니다.
TNS-12545는 SQL*NET TCP/IP V1에서 발생하는
ORA-6105 "NETTCP:remote host is unknown"과 비슷합니다.
* TNS-12545를 진단하는 단계
1. 호스트 이름을 이용하여 호스트에 대해 TELNET과 PING을 실행해 보십시요. 즉
PING <server> 또는 TELNET <server>를 실행해 보십시요. 호스트 이름을
사용하여 PING이나 TELNET을 성공적으로 실행할 수 없으면, 먼저 TCP/IP 구성을
점검해야 합니다. PING나 TELNET의 WINDOWS 버전을 사용하여 해 보십시요. 몇몇
DOS 버전이 잘 작동하더라도 WINDOWS 구성에 문제가 있으면 WINDOWS 버전에서
에러가 발생할 수 있습니다.
2. 서버에서 루프백을 수행하여 서버쪽이 정확하게 설정되었는지 확인하십시오.
루프백을 수행하려면 데이타베이스가 있는 MACHINE에서 아무 툴이나 호출하고,
TNSNAMES.ORA에 WINDOWS 클라이언트에 사용한 것과 같은 ADDRESS 매개 변수를
사용하여 SQL*NET V2를 통해 데이타베이스에 연결해 보십시요.
3. 다음에는 사용자의 TCP/IP 소프트웨어가 IP 주소의 이름 분석을 위해 PC에서
DOMAIN NAME SERVICE(DNS)를 사용하는지 아니면 파일 찾아보기를 사용하는지
점검하십시요.
4. DNS를 사용한다면, DNS에 해당하는 모든 드라이버를 올리도록 하십시요. 예를
들어, SUN PC/NFS는 RNMNIS.EXE를 올려야만 Naming Information Service를
사용할 수 있게 됩니다.
5. DNS를 사용하지 않는다면, HOST 파일에 연결해야 할 호스트의 항목이 있는
지 확인하고, 만약 없으면 추가하십시요. WINDOWS용 TCP/IP 어댑터는 원래
TCP/IP 업체가 예상한 디렉토리에 상주하는 HOST 화일을 사용합니다. HOST
파일의 각 항목 뒤에는 반드시 키리지 리턴을 넣어야 합니다. 또한 그러한
서비스에 필요한 드라이버를 모두 점검해야 합니다. 예를 들어, SUN PC/NFS는
그러한 서비스를 올리려면 RNMFILE.EXE가 필요합니다.
6. WINDOWS 호출을 사용하지 않고 open() 호출을 사용했기 때문에 파일 핸들이
초과할 수 있습니다. SQL*NET V1은 여기에 해당하지 않습니다. 이 버그는 버전
2.1.5에 와서 해결되었습니다.
7. 연결을 시도하여 여전히 TNS-12545가 나오면, TNSNAMES.ORA 파일의 ADDRESS
부분 아래에 있는 HOST 매개 변수에 호스트 이름을 지정하지 말고 IP 주소를
지정하는 것도 한 가지 해결책이 될 수 있습니다. 다음 예를 참조하십시요.
HOST=139.141.61.64

I've downloaded 11i.10.2 from the edelivery site, and unzipped all files to E:, so
my staging area looks like E:\startCD, E:\oraDB, etc.You have to correct the set up of the stage area directory. The installation file system must contain a directory, Stage11i, in which the downloaded files will be unzipped. The file structure under that top-level directory will be automatically created when unzipping the files.
So, all what you need to do is the following:
- Create new directory E:\Stage11i
- Place all the zip files you have downloaded under this directory
- Unizip the files within this directory
By the end, you should have a directory structure similar to the following:
E:\Stage11i\startCD
E:\Stage11i\oraDB
E:\Stage11i\oraAppDB
E:\Stage11i\oraiAS
E:\Stage11i\oraApps
E:\Stage11i\oraNLS
Run Rapid Install from the Stage11i directory.

TNS-01151: Missing listener name

I found the following error in er.log. Does anyone know what this means? I am unable to start the listener service because of this.

Random TNS-12545 errors

Most of the time my customers sqlnet connections work just fine. Every day or so they get TNS-12545 errors between their servers and databases and across database links for about a minute or two and then things go back to normal. The errors occurr at random times.
We are looking at network and server things that might cause a slow response.
This is Oracle 10.
Are there any specific oracle net parameters that would provide a workaround to avoid this problem?

Most of the time everything is okay but once or twice per week an error occurs and the user gets TNS-12545 errors.
This is Oracle 10. I can't post the configuration files.
I think I need something in the OracleNet configuration that would cause OracleNet to wait a little longer on the connection.

TNS-01169: The listener has not recognized the password

Dear All
I am using Oracle8 Enterprise Edition Release 8.0.5.0.0 on Windows XP
My problem is that
When I tried to stop listener by using lsnrctl80 stop it gives me the subjected error,
while when I stop the listener from Windows Servcies it stops successfully.
Plz note that when I start listener by using lsnrctl80 start it starts successfully.
Following is the information of listener.ora
LISTENER =

(ADDRESS=
(PROTOCOL= TCP)
(Host= it-rhassan)
(Port= 1521)
STARTUP_WAIT_TIME_LISTENER = 0
CONNECT_TIMEOUT_LISTENER = 10
TRACE_LEVEL_LISTENER = 0

(SID_NAME = GL)
(SID_DESC =
(GLOBAL_DBNAME = it-rhassan)
(SID_NAME = ERP)
PASSWORDS_LISTENER = (oracle)
Plz note that I alsed tried to give password same as the internal passwrod, and remove PASSWRODS_LISTENER but same error occured in each cases.
Thanks in advance for your help

I did not find the exact solution on the suggested site. only found the Error Code and description.
Then I searched on Google.com and found following result which has successfully solved my problem.
LSNRCTL> change_password
Old password:
New password:
Reenter new password:
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=DBDEV1)(PORT=1526)))
TNS-01169: The listener has not recognized the password
LSNRCTL> set password

TNS-01169: The listener has not recognized the password
LSNRCTL>
Regardless of how you enter the password, through a single line or on the prompt, the change will not be successful. To change the password, you have to remove the line passwords_listener in the file listener.ora and then change the password.
Thanks

Need help for TNS-00511: Kein Listener

Hi everybody,
by testing the Listener status after installing the Oracle Client for second time I get the following results, can you please give me a feedback if the listener is really working or if I need to correct something regarding the results?. I would really appreciate:

There is no listener.ora under the Oracle Client Home but a backup: listener.bak, because everytime I try to put it as listener.ora, the Siebel Listener crashes.

Furthermore I did:

TNS-01106: Listener process with the name SIEBELDBTEST was already started.
What I did is to delete the OracleOraDb10g_home1TNSListener with the Net Assistant, because it was causing the problem that I couldn't start the SiebelDBTest Listener.
Should I correct that?

Listener Error "TNS-01189: The listener could not authenticate the user"

Good morning. We have a dual-homed (one home is 10.2.0.4 and the other is 10.2.0.5) server running a 10.2.0.5 listener. We accidentally applied the April2011 PSU to the 10.2.0.5 home without shutting down the listener. The PSU installed correctly but the listener now gives the error "TNS-01189: The listener could not authenticate the user" when any attempt is made to run the following lsnrctl commands: reload, stop, services, and status. When the start command is issued, it informs us the listener is already running (which is correct). The listener is working properly handing off database connections but we cannot administer it.
Would installing the PSU while the listener was running cause this problem? Any idea on how to reload the listener? We even went so far as to deinstall 10.2.0.5 on the server and reinstall it with a clean cloned copy of 10.2.0.5. We also tried to create a new listener (which it did) but would not start the new listener. It said one listener was already running.
From EM Grid Control, we can administer the listener (make basic changes to the listener.ora file) but we cannot stop the listener from EM Grid Control either. (Not a surprise.)
Ideas? Thoughts?

TNS-01189: The listener could not authenticate the user
I have read the Metalink doc (Doc ID 285439.1) and it seems like the two homes are causing some type of conflict. I am just not sure how to resolve the issue. I tried unsetting ORACLE_HOME in both 10.2.0.4 and 10.2.0.5 SID environments. The error I get then is the basic TNANAMES error. That sequence looks like this:
+>unset ORACLE_HOME+
+>echo $ORACLE_HOME+

Am I not clearing out the ORACLE_HOME properly (as suggested in the Metalink doc)?
