Upgraded to Spotlight on RAC 2.0 Can no longer connect to some instances. I am able to connect via SQLPLUS.
Error message: ORA-12521 TNS: listener does not currently know of instance requested in connect descriptor.
1. Select Spotlight on Oracle RAC connection in Connection Manager and click Connect button (or double click the Icon) to connect with Oracle RAC
2 When "Verify Cluster Connection Details" dialog appears, click on the TNS Entry field for each node and select the correct tns entry for each node.
3. Verify the status is OK
4. Click the OK button to connect
