DBC:Errors/DBC-E033

[DBC-E033] <sid>: Instance not available (ORA-???:<Oracle message>)

The instance <sid> is not in OPEN mode, so dbcollect cannot connect to it using TNS connection string. The instance may be in MOUNTED mode (Standby database) or in STARTED mode.

Solution:

• Skip the instance using an N in the 2nd field of the credentials file.
• Open the database (if it should be opened)
• Run dbcollect as oracle (or root) user without credentials file (in which case it connects as SYSDBA without requiring a TNS connection
