如何清理oracle 10g服务器中的临时表空间,请提供linux平台的步骤

Question

我想清理Temp其具有数据文件表空间 temp01.dbf和temp02.dbf,所以请给我建议,我应该放下 temp01.dbf文件或者删除临时表空间.Temp表空间的数据文件如下

33G     temp01.dbf
1.5G    temp02.dbf

Answer 1

1. 创建临时表空间温度

      CREATE TEMPORARY TABLESPACE TEMP2 TEMPFILE  ‘/u01/app/oradata/temp01.dbf? SIZE 2000M ; 
   

2. 移动默认数据库临时表空间

      ALTER DATABASE DEFAULT TEMPORARY TABLESPACE temp2;
   

3. 确保没有会话正在使用您的Old Temp表空间

      a.  Find Session Number from V$SORT_USAGE: 
     SELECT USERNAME, SESSION_NUM, SESSION_ADDR FROM V$SORT_USAGE; 
   
      b.  Find Session ID from V$SESSION:
   
     If the resultset contains any rows then your next step will be to find the SID from the V$SESSION view. You can find session id by using SESSION_NUM or SESSION_ADDR from previous resultset.
   
     SELECT SID, SERIAL#, STATUS FROM V$SESSION WHERE SERIAL#=SESSION_NUM;
     OR
     SELECT SID, SERIAL#, STATUS FROM V$SESSION WHERE SADDR=SESSION_ADDR; 
   
      c.  Kill Session:
   
      Now kill the session with IMMEDIATE.
   
       ALTER SYSTEM KILL 'SID,SERIAL#' IMMEDIATE; 
   

4. 删除临时表空间

      DROP TABLESPACE temp INCLUDING CONTENTS AND DATAFILES;
   

5. 重新创建表空间温度

      CREATE TEMPORARY TABLESPACE TEMP TEMPFILE '/u01/app/temp/temp01.dbf? SIZE 2000M;
   

6将Tablespace Temp移回新临时表空间

       ALTER DATABASE DEFAULT TEMPORARY TABLESPACE temp;

7. 删除临时表空间temp

     DROP TABLESPACE temp2 INCLUDING CONTENTS AND DATAFILES;
