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 gt 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 gt net start OracleOraDb10g home1TNSListener    Try to start the listener service using lsnrctl from DOS prompt    lsnrctl start

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 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

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

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

1 Check the Environment variables  must be set for System and not for user    ORACLE HOME   C  oraclexe app oracle product 11 2 0 server ORACLE SID   XE   2 Check if you have the right definition in listener ora  XE      DESCRIPTION LIST        DESCRIPTION          ADDRESS    PROTOCOL   IPC  KEY   EXTPROC1          ADDRESS    PROTOCOL   TCP  HOST   localhost  PORT   1521              DEFAULT SERVICE LISTENER    XE    3 Restart the service  Services   OracleServiceXE   After that you may see a new service called OracleXETNSListenerXE  There is already an old OracleXETNSListener   I started both and then I was able to make a successful connection   Edit   If everything is running but you still can t connect  check if there is no error  ORA-12557  TNS protocol adapter not loadable   To correct the error go back to the Environment variables and this time edit the one called  Path  Be sure that C  oraclexe app oracle product 11 2 0 server bin is somewhere at the beginning  definitely before any other path pointing to a different version of the Oracle DB

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

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  I tried to start the listener via console    gt  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    Check if Oracle listener ora or sqlnet ora file contains special characters Check if Oracle listener ora or sqlnet ora  file are in wrong format or syntax Check if Oracle listener 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

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
