T he command completed successfully
I encountered the same problem and reason being: Mine is a personal windows PC. And i have modified the computer name and the same did not reflect in listener.ora. Updating ORACLE_HOME\network\ADMIN\listener.ora with updated host name fixed the issue.
I encounter similar problem when installing oracle 11gR2 on Windows 2012 server. the problem is solved when I run cmd.exe as Admistrator privilege and run "lsnrctl start LISTENER".
In my case the listener service would not start because it was set to listen to a VPN connection as well to other serveral interfaces.
Once I connected to the VPN, it just started.
However, @Imre's trick with "lsnrctl start" put me to the right track.
The listener service is stopped in services.msc.
User password was changed.
services.msc.I solved it by updating listener.ora file inside oracle directory oraclexe\app\oracle\product\11.2.0\server\network\ADMIN.
Why did it happen to me was because I changed my system name but inside listener.ora there was old name for HOST.
This might be one of the reasons... for those who still face such issue might think of this possibility as well.
In my case, I tried to start the listener via console:
> lsnrctl star
This command printed the following error:
TNS-12560: TNS:protocol adapter error
TNS-00583: Valid node checking: unable to parse configuration parameters
So, I performed the following actions:
listener.ora or sqlnet.ora file contains special characterslistener.ora or sqlnet.ora` file are in wrong format or syntaxlistener.ora or sqlnet.ora file have some left justified parenthesis which are not accepted by oracle parser.Have a look at these files and check the proper syntax. If possible remove/rename sqlnet.ora and try to restart the listener. Or remove/rename both listener.ora or sqlnet.ora file and recreate it properly. These will defenitely resolve the issue.
I had the same problem on 11.201 on Windows. After: additional install 11.203 64bit server and client in new folders. PATH environment variable was changed right after install. Error in listener appeared after listener service restart. In my case there was a night time and number of windows updates, so windows server restart helped us. Also I cleaned listener.log file according to http://pavandba.com/tag/tns-12560-tns-protocol-adapter-error/, it was surprisingly big.
In my Windows case the listener would not start, and 'lsnrctl start' would hang forever. The solution was to kill all processes of extproc. I suspect it had something funny to do with my vpn
In my case somehow windows listener service had stopped working so I was not able to connect to Qracle using SQL Developer. However I was able to connect through sqlplus.
Below solution worked for me:
First, ensure that your listener service is running.
C:\Documents and Settings\ME>lsnrctl status
If the listener service is not running, re-start the listener service using the Windows task manager or use the DOS command line utility to re-start the Windows service with the net start command:
C:\Documents and Settings\ME>net start OracleOraDb10g_home1TNSListener
Try to start the listener service using lsnrctl from DOS prompt.
lsnrctl start
Same happened to me after I changed computer name. To fix that, just locate listener.ora file and replace old computer name with the new one
I had the same problem. Solution in my case: run CMD as ADMINISTRATOR. then type and execute: "lsnrctl start" wait about 2 minutes then should work. (in my case was only 50 seconds, but just to be on the safe side)
I managed to resolve the issue that caused the configuration to fail on a docker container running the Hortonworks HDP 2.6 Sandbox.
If the initial configuration fails the listener will be running and will have to be killed first:
ps -aux | grep tnslsnr
kill {process id identified above}
Then next step is then to fix the shared memory issue which makes the configuration process fail.
Oracle XE requires 1 Gb of shared memory and fails otherwise (I didn't try 512 mb) according to https://blogs.oracle.com/oraclewebcentersuite/implement-oracle-database-xe-as-docker-containers.
vi /etc/fstab
change/add the line to:
tmpfs /dev/shm tmpfs defaults,size=1024m 0 0
Then reload the configuration by:
mount -a
Keep in mind that the next time you restart the docker container you might have to do 'mount -a'.
Check that ORACLE_HOME environment variable is pointing to the correct oracle home. In my case it was changed by another software installation.
