在执行该命令时出现下列错误

SYS@PROD>alter system set UTL_FILE_DIR=‘/home/oracle‘,‘/home/oracle/temp‘,‘/home/oracle/scripts‘ scope=spfile;
alter system set UTL_FILE_DIR=‘/home/oracle‘,‘/home/oracle/temp‘,‘/home/oracle/scripts‘ scope=spfile
*
ERROR at line 1:
ORA-32001: write to SPFILE requested but no SPFILE is in use

解决：

1.查看是否有spfile

SYS@PROD>show parameter spfile;

NAME                                 TYPE                             VALUE                      
------------------------------------ ---------------------
spfile                                   string

2.从pfile创建spfile

SYS@PROD>create spfile from pfile;

File created.

3.关闭数据库

SYS@PROD>shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

4.启动数据库

SYS@PROD>startup
ORACLE instance started.

5.查看是否有spfile文件

SYS@PROD>show parameter spfile;

spfile                               string                 01/app/oracle/product/11.2.0/db_1/dbs/spfilePROD.ora
6.再次执行该命令，问题解决

SYS@PROD>alter system set UTL_FILE_DIR=‘/home/oracle‘,‘/home/oracle/temp‘,‘/home/oracle/scripts‘ scope=spfile;

System altered.
