I put only SCAN IP entry in
C:\WINDOWS\system32\drivers\etc\hosts file
rac-scan.acc.com rac-scanNow it is connecting to database.
The problem is SRVCTL status database shows like this while database is up,
[oracle@rac2 ~]$ srvctl status instance -d racdb -i racdb1,racdb2
Instance racdb1 is not running on node rac1
Instance racdb2 is not running on node rac2
[oracle@rac2 ~]$
[oracle@rac2 ~]$ srvctl status database -d racdb
Instance racdb1 is not running on node rac1
Instance racdb2 is not running on node rac2
[oracle@rac2 ~]$
After Suggestion by this thread
SRVCTL command not showing properly
It is showing
[oracle@rac1 ~]$ srvctl status database -d racdb
Instance racdb1 is running on node rac1
Instance racdb2 is running on node rac2
[oracle@rac1 ~]$
As well as established connection from client.
Thanks Sebastian
