How many instances ?

How many instances ?

 

  

Hi,



We have only one db and one instance running on our Solaris machine.
However when I run the following command, it says two instances running.





lsnrctl status



Here is the output:



Service "ITNSTAGE" has 2 instance(s).

Instance "ITNSTAGE", status UNKNOWN, has 1 handler(s) for this
service...

Instance "ITNSTAGE", status READY, has 1 handler(s) for this
service...

Service "ITNSTAGEXDB" has 1 instance(s).

Instance "ITNSTAGE", status READY, has 1 handler(s) for this
service...

Service "PLSExtProc" has 1 instance(s).

Instance "PLSExtProc", status UNKNOWN, has 1 handler(s) for this
service...



Does anyone see any problem here?



Thanks
