We have a two node Oracle RAC database and three scan listeners. These listeners must be up in any one of the two servers. When we do a shutdown the listener migrate to the other cluster node.They are monitored through the probe processes, but when it changes of node we have a false alarm since it is up at the other server.How can we monitor those listeners if they can be active in anyone of the servers and migrate to other node sometimes?
Hello Magda, can you please check with your DBAs and cluster admins if this failover of the scan listener process is documented in the Oracle logs or Cluster logs. If this is the case, I would suggest to use logmon probe to monitor this process.
Hello Britta, we will check our log files and see if it's possible to use logmon to monitor the scan-listeners.
I will let you know how was the test.
Thanks a lot,
Hello Magda, I can see here a second option using logmon probe?
You can use logmon to run tnsping command and generate an alarm if service is down. something like this?
You can set logmon local or remote
