oracle pdb 临时表空间,12c datagurad 创建临时表空间遇到的问题

1.主库添加临时文件

SQL> create temporary tablespace temp_1 tempfile '+datadg' size 10m;

Tablespace created.

SQL> alter system archive log current;

System altered.

col file_name for a50;

set lines 150

select file_name,tablespace_name from dba_temp_files;

FILE_NAME TABLESPACE_NAME

-------------------------------------------------- ------------------------------

+DATADG/ORCL/TEMPFILE/temp.265.954623079 TEMP

+DATADG/ORCL/TEMPFILE/temp_1.605.963692313 TEMP_1

SQL>

2.查看备库

SQL> select open_mode from v$database;

OPEN_MODE

--------------------

READ ONLY WITH APPLY

SQL> col file_name for a50;

SQL> set lines 150

SQL> select file_name,tablespace_name from dba_temp_files;

FILE_NAME TABLESPACE_NAME

-------------------------------------------------- ------------------------------

+DATADG/ORCLDG/TEMPFILE/temp.406.962961491 TEMP

SQL>

--查看备库日志

*********************************************************************

WARNING: The following temporary tablespaces contain no files.

This condition can occur when a backup controlfile has

been restored. It may be necessary to add files to these

tablespaces. That can be done using the SQL statement:

ALTER TABLESPACE ADD TEMPFILE

Alternatively, if these temporary tablespaces are no longer

needed, then they can be dropped.

Empty temporary tablespace: TEMP_1

*********************************************************************

解决方法

备库直接添加一个临时文件

3.备库执行

SQL> alter tablespace temp_1 add tempfile '+datadg' size 10m;

Tablespace altered.

SQL> col file_name for a50;

SQL> set lines 150

SQL> select file_name,tablespace_name from dba_temp_files;

FILE_NAME TABLESPACE_NAME

-------------------------------------------------- ------------------------------

+DATADG/ORCLDG/TEMPFILE/temp.406.962961491 TEMP

+DATADG/ORCLDG/TEMPFILE/temp_1.342.963694567 TEMP_1

重启备库,查看告警日志,无报错。

小结

1.主库添加临时表空间,备库数据字典存在表空间信息。

2.备库dba_temp_files数据字典不存在临时文件记录。

3.备库open状态直接添加一个临时文件即可。

4.ADG的文件管理方式和单机、RAC管理方式不同,需要大家多去测试。
