method one:
sqlplus '/ as sysdba' EXEC DBMS_XDB.SETHTTPPORT(0);
Method Two:
Edit the $ORACLE_HOME/dbs/initSID(init).ora file and comment the following lines:
#dispatchers='(PROTOCOL=TCP) (SERVICE=ORCLXDB)'
Then restart the database:
shutdown immediate; create spfile from pfile; startup;
If you check that port 8080 has not been closed by the following command, close the database, monitor, and restart the database server:
netstat -an | grep 8080
Turn off listening:
lsnrctl stop
Close the database:
sqlplus '/ as sysdba' shutdown immediate;
Restart the server:
reboot
Start listening:
lsnrctl start
Start the database:
sqlplus '/ as sysdba' startup;
Finally check if the port is up:
netstat -an | grep 8080
