The
listener supports no services
The
command completed successfully
I
try to do “alter system register” and try multiple things. But nothing work out
for me.
Reason
for no service are displayed in the listener status, No service are register
with the listener. To register the service in the listener, we need to
configure local_listener,remote_listener
& listener_networks properly
Note: I am
configuring the listener_networks, because
I use a second IP or different IP for the data guard services.
Please find same
local_listener, remote_listener & listener_network parameters
alter system set listener_networks='((name=BHU1_n1)(local_listener=
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=bhuora01-dg-vip)(PORT=1521))))
(remote_listener= (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=bhuora02-dg-vip)(PORT=1521)))))'
sid='BHU1_1' scope=spfile;
alter system set listener_networks='((name=BHU1_n2)(local_listener=
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=bhuora02-dg-vip)(PORT=1521))))
(remote_listener= (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=bhuora01-dg-vip)(PORT=1521)))))'
sid='BHU1_2' scope=spfile;
alter system set
local_listener='(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=bhuora01-vip)(PORT=1524)))'
sid='BHU1_1' scope=spfile;
alter system set
local_listener='(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=bhuora02-vip)(PORT=1524)))'
sid='BHU1_2' scope=spfile;
alter system set remote_listener='racorabhua-scan:1529' SID='ZE1_1'
scope=spfile;
alter system set remote_listener='racorabhua-scan:1529' SID='ZE1_2'
scope=spfile;
Once you restart the database, if you see the status
of the listener. We should see the service up and running
If you still feel that service are running, then
issue the below command on each instance
SQL> ALTER SYSTEM REGISTER;
bhuora01[BHU1_1]>lsnrctl stat LSNR_VIPB_BHU1
