在設定DATA GUARD 時，修改了系統引數，重啟資料庫後出錯：

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup;
ORA-32004: obsolete or deprecated parameter(s) specified for RDBMS instance
ORA-16019: cannot use LOG_ARCHIVE_DEST_1 with LOG_ARCHIVE_DEST or LOG_ARCHIVE_DUPLEX_DEST
SQL> alter system set log_archive_dest_1='+RECOVERY/racdb/archivelog/' scope=spfile;
alter system set log_archive_dest_1='+RECOVERY/racdb/archivelog/' scope=spfile
*
ERROR at line 1:
ORA-01034: ORACLE not available
Process ID: 0
Session ID: 19 Serial number: 48797

計劃從spfile 生成pfile 檔案：

[[email protected] ~]$ sqlplus /nolog

出錯，找不到檔案和目錄，我環境為RAC+ASM.

指定檔案

SQL> create pfile='init.ora' from spfile='+data/racdb/spfileracdb.ora';

File created.

SQL> startup pfile='init.ora';
LRM-00109: could not open parameter file 'init.ora'

SQL> shutdown abort;

把pfile 修改回以前檔案。

[[email protected] dbs]# cp initracdb1.ora.org initracdb1.ora
cp：是否覆蓋“initracdb1.ora”? y

（修改前有備份此檔案）

[[email protected] dbs]# cat initracdb1.ora
SPFILE='+DATA/racdb/spfileracdb.ora'

再重新建立 SPFILE:

create spfile='+data/racdb/spfileracdb.ora' from pfile='/opt/app/oracle/product/11.2.0/dbs/init.ora';

(

要指定pfile 具體檔案。不然生成pfile 無效，

我在這裡錯了。出現錯誤：

ORA-01506: missing or illegal database name

)
