During our recent installation/configuration of pushing agents out for OEM Cloud 12c, my team somehow deleted or removed (2) of our Scan_Listeners. Prior to our mishap with OEM Cloud, we had all (3) Scan_Listeners:
Now we are only left with a single, Scan_Listener01. Does this seem appropriate to recreate:
[grid@mynode]$ srvctl add scan_listener -netnum 2 -listener testscan -endpoints TCP:1528
[grid@mynode]$ srvctl config scan_listener -netnum 2 SCAN Listener TESTSCAN_SCAN1_NET2 exists. Port: TCP:1528 Registration invited nodes: Registration invited subnets:
[grid@mynode]$ srvctl start scan_listener -netnum 2
[grid@mynode]$ srvctl status scan_listener -netnum 2 SCAN Listener TESTSCAN_SCAN1_NET2 is enabled SCAN listener TESTSCAN_SCAN1_NET2 is running on node SalesSrv146
I believe these scan listeners are initially created during the Grid Infrastructure installation.
