ORA-01652 - 无法在表空间(oracle 10)中将临时段扩展4096

问题:

我是Oracle的新手,我想我错过了一些导致我的临时表空间填满的基本知识。

我打开与数据库的连接并多次运行pl / sql过程来插入行。每次运行该过程时,TEMP表空间中的空闲块数量都会减少。当空闲块的数量太少时,该过程将失败并出现错误" ORA-01652 - 无法在表空间"中将临时段扩展4096。如果我关闭数据库连接,TEMP表空间中的空闲块将重置为总块数,我可以继续重新运行该过程。如何在不关闭和打开数据库的情况下释放TEMP表空间块?我以为我需要添加一个提交声明,但这没有用。

由于

代码:

查询检查free_MB(每次运行程序时都会减少)。

SELECT tablespace_name,
total_blocks,
used_blocks,
free_blocks,
total_blocks*16/1024 as total_MB,
used_blocks*16/1024 as used_MB,
free_blocks*16/1024 as free_MB
FROM v$sort_segment; 

SQL我多次运行,直到free_mb减少到0并且我得到错误:

DECLARE
  p_samples LOG_ENTRY_ARRAY;
  longSample clob;
BEGIN
  For v_COUNTER IN 1..32767 LOOP
    longSample := longSample || 'a';
  END loop;
  -- initialize the input
  p_samples := LOG_ENTRY_ARRAY(longSample, 'short sample');
  for i in 1..100 LOOP
    INSERT_SUMMARY_SAMPLES('TABLE1', 1000, 1, 2, p_samples);
  END loop;
  commit;
END;

调用的过程将一堆插入到两个表中:

create or replace 
PROCEDURE INSERT_SUMMARY_SAMPLES 
(
  p_TABLE_NAME IN VARCHAR2  
, p_TS IN NUMBER  
, p_SIGNATURE_ID IN NUMBER  
, p_COUNT IN NUMBER  
, p_SAMPLES IN LOG_ENTRY_ARRAY  
) AS 
  tbl_summary varchar2(30);
  tbl_samples varchar2(30);
  summary_id number(10,0);
  sample varchar2(32767);
BEGIN      
  tbl_summary := 'TBL_' || p_TABLE_NAME || '_SUMMARIES';
  tbl_samples := 'TBL_' || p_TABLE_NAME || '_SAMPLES';

  -- insert summary and get the id
  EXECUTE IMMEDIATE 'INSERT INTO ' || tbl_summary 
    || ' (agg_start_ts, signature_id, count, num_samples) VALUES (:a,:b,:c,:d) returning id into :1' 
    using p_ts, p_signature_id, p_count, p_SAMPLES.count returning into summary_id;
  dbms_output.put_line('new summary_id is : ' || summary_id);
  -- insert samples
  FOR i in 1..p_SAMPLES.count LOOP
    -- convert clob to varchar2
    CLOB_TO_VARCHAR(p_SAMPLES(i),sample);
    EXECUTE IMMEDIATE 'INSERT INTO ' || tbl_samples || ' (summary_id, log_entry) VALUES (:a,:b)' using summary_id, sample;
    -- dbms_output.put_line('insert sample : ' || TO_CHAR(p_SAMPLES(i)));
  END LOOP;  
END INSERT_SUMMARY_SAMPLES;

CLOB_TO_VARCHAR是另一个程序:

create or replace 
PROCEDURE CLOB_TO_VARCHAR (
  p_clob IN CLOB,
  p_varchar OUT VARCHAR2
  )
AS
  v_output varchar2(32767);
  l_amount BINARY_INTEGER := 32767;
  l_pos INTEGER := 1;
  l_clob_len INTEGER := 0;
BEGIN
  l_clob_len := DBMS_LOB.getlength (p_clob);
  WHILE l_pos < l_clob_len
  LOOP
    dbms_lob.READ(p_clob, l_amount, l_pos, v_output);
    l_pos := l_pos + l_amount;
  END LOOP;
  p_varchar := v_output;
END CLOB_TO_VARCHAR;

2 个答案:

答案 0 :(得分:0)

答案 1 :(得分:0)

我猜你在某个地方有一个临时吊球,但它没有被明确释放。 LOG_ENTRY_ARRAY定义在哪里?
