Operations on Scan listener

There arethe some example of stop/start/add/relocate SCAN Listener command.

Here is example:

Example: srvctl add scan_listener -l SCAN_LISTENER4

I have 12.0.1.2 node RAC system on Linux 64 bit.

I had some e-mails from our developer team about database connection problems. They got “ORA-12541: TNS:no listener” error message.

I started to investigate issue by checking current status of services by using below command:

crsctl stat res -t

I noticed that SCAN_LISTENER service status were UNKNOWN.
