Perfect Solution to ORA-12514

Question

Hi All, here is the solution for :
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
STEP 1 : SET ORACLE_SID = <YOUR_SID>
STEP 2 : sqlplus "/as sysdba"
If u get as insufficient privilleges , then
Enter username : sys as sysdba
Password : your db password
SQL>
Now, take a moment and see if u have init<your_sid>.ora file in path as shown below :
C:\app\q741372\product\11.1.0\db_1\database\
If not you can create the same, find the spfile of you sid (from same location), copy the contents and paste the same into new text document.
Remove all the junk characters from new created file and save it in same location as init<your_sid>.ora
Then back to sql prompt again.
SQL> startup pfile='C:\app\q741372\product\11.1.0\db_1\database\init<your_sid>.ora';
Database will be mounted and started
Now you manually put the listner entry...
sql>create spfile from pfile
sql> shu immediate;
sql> startup
sql> alter system set local_listener='(address=(protocol=tcp)(host=localhost)(port=1521))' scope=both;
And see if the port number in your listener.ora and tnsnames.ora is same, if not change it to the port number which you specify in above command
sql> alter system register;
That's it... your database will be working fine... Enjoy !!!!!

Please include DB version, OS version information in your post.
You can even post link to your previous post where you were fighting with this issue.
Personally I never had similar situation. In my databases local_listener parameter is empty.
