Hi All,
I have redundant system with Oracle database as Primary on one side and Standby on the other.

1) When the database on Active is up and Running as Primary and on Inactive it is started and mounted as Standby, I am able to connect from Active database to the Standby and viceversa.

2) Then I shutdown the database on both the sides. Then I tried to connect from Active to Standby database and viceversa. I was able to connect this time as well

3) The active and standby database were shutdown . Then I stopped the listener and restarted it. This time when I tried to connect from Active to Standby and I was unable to connect. It gave me the error ORA-12514 The listener supports no services

4) I started the Active database. Then I tried to connect to Active from Standby side. This time I was able to connect.

So it appears that ever since I stopped and started the listener, I am able to connect to the other side only if the instance is up. If the instance is down then I get an error.

This was not the case before re-starting the listener.

Could you please let me know why I am facing this issue after restarting the listener?

Waiting for your kind reply.

Thanks and regards,
Kaustubh Kane.

Something changed.

Are these "sides" to which your refer, topside & bottomside OR leftside & rightside OR inside & outside?

Please read & follow posting guidelines in STICKY post at top of this forum.

Hi,

The "sides" are the Active and the Standby side. Sorry if I was not very clear.

You said something changed. Do you mean that something might have changed in the tnsnames.ora or listener.ora before the listener was restarted and hence I faced this issue?

Waiting for your kind reply.

Thanks and regards,
kaustubh Kane.

What's the entry of your listener file? Try lsnrctl status to check whether it can read it or not. Where error comes. Where it can't read. Fix it.
