FIX- ORA-00119: invalid specification for system parameter LOCAL_LISTENER ORA-00132: syntax error or unresolved network name 'db11g'

EASY fix.

Instead of spfile, start your database from pfile, and if the database starts then create a new spfile from it. 

Otherwise remove the local_listener parameter from the pfile and spfile and try starting it. 

$ cd $ORACLE_HOME/dbs

$  ls -rt

$ vi initdb11g.ora

and remove 

*.local_listener='db11g'

$ vi spfiledb11g.ora

and remove 

*.local_listener='db11g'
