Hi,
We are not able to connect to RAC instance unless we stop the listener
using svrctl command and restart it again using lsnrctl command,
Do I need to add anything in tnsnames.ora files since out listener name
is listener_dev-rhas2 and not listener?
$ srvctl status nodeapps -n dev-rhas2
VIP is running on node: dev-rhas2
GSD is running on node: dev-rhas2
Listener is running on node: dev-rhas2
ONS daemon is running on node: dev-rhas2

Following is entry in tnsnames.ora:

ERROR:
ORA-12516: TNS:listener could not find available handler with matching
protocol
stack
This only works If i stop the listener using svrctl then start the
listener with lsnrctl start.
srvctl stop listener -n dev-rhas2
lsnrctl start
