文档解释
ORA-19802: cannot use DB_RECOVERY_FILE_DEST without DB_RECOVERY_FILE_DEST_SIZE
Cause: There are two possible cause for this error: 1) The DB_RECOVERY_FILE_DEST parameter was in use when no DB_RECOVERY_FILE_DEST_SIZE parameter was encountered while fetching initialization parameter. 2) An attempt was made to set DB_RECOVERY_FILE_DEST with the ALTER SYSTEM command when no DB_RECOVERY_FILE_DEST_SIZE was in use.
Action: Correct the dependency parameter definitions and retry the command.
