Activate a Database listener

Question

Hi Friends,
I have created a database in 10g. The same machine has 9i instance of DB running in it.
After creating the 10g DB i could see a red arrow pointing downward for all the three divisions (DB instance, Listener, Agent connection to database) in this URL of my oracle server http://localhost:1158/em/
Someone guide me on how to start the DB instance and activate the DB listener

Answer 1

Please follow my next article which use :
I need a second listener because the node that I worked has two oracle software one for oracle9i and for oracle10g. I leave the listener LISTENER for the oracle9i software and I create a new one LISTERNER10G for oracle10g software.
I create the second listener via netca and I statically configure the database sid via netmgr .After that I made the following changes in init<SID>.ora and tnsnames.ora file.
tnsnames.ora
LISTENER10G=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.40.250)(PORT=1526)))
alter system set LOCAL_LISTENER= LISTENER10G scope=both;
Some very importand database parameters are the following.
service_names=DB_SISII
db_name=DB_SISII
instance_name=DBSISII
Note that when I create the database I set database name as DB_SISII and SID as DBSISII
Lsnrctl>set current_listener LISTENER10G
Lsnrctl>services
Service "DB_SISII" has 2 instance(s).
Instance "DBSISII", status UNKNOWN, has 1 handler(s) for this service...
Handler(s):
"DEDICATED" established:0 refused:0
LOCAL SERVER
Instance "DBSISII", status READY, has 1 handler(s) for this service...
Handler(s):
"DEDICATED" established:0 refused:0 state:ready
LOCAL SERVER
I can access the database via the following tnsnames.ora entry
DBSISII =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.40.250)(PORT = 1526))
(CONNECT_DATA =
(SERVICE_NAME = DB_SISII)
Some issues exist for database console and may be able to be solved by:

Edit the following line in emoms.properties

emctl stop dbconsole
emctl start dbconsole
