I have a oracle RAC /12c/. I got these error when I try start the base from node2.
```ORA-01078: failure in processing system parameters ORA-01565: error in identifying file '+DATA/mydborcl/spfilemydborcl.ora' ORA-17503: ksfdopn:2 Failed to open file +DATA/mydborcl/spfilemydborcl.ora ORA-29701: unable to connect to Cluster Synchronization Service```
I am very new to oracle. How can I start the mount the database on node2 and solve the problem?
