这里可以得出信息如下：
1)系统环境AIX 5.3 9.2.0.8.0 RAC
2)报错的语句是收集TINEXWORK_DATA表相关统计信息
3)是由于SQL*Plus收集统计信息使用并发导致该错误

查询MOS发现
Bug 5887047: ORA-00600 [KSXPRQFRE3] TRACE WHEN GATHERING OPTIMIZER STATISTICS描述相符：
1）数据库版本9.2.0.8
2）收集统计信息操作导致
3）STACK TRACE一致

处理建议
针对官方没有给出明确的解决方案，因为该问题出现概率比较低，如果经常出现需要考虑升级数据库版本

数据库版本

Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi
PL/SQL Release 10.2.0.5.0 - Production
CORE 10.2.0.5.0 Production
TNS for Linux: Version 10.2.0.5.0 - Production
NLSRTL Version 10.2.0.5.0 - Production

通过MOS发现该错误在10.2.0.5上有相关描述

This problem is hit only in 10.2.0.5, up to PSU 10.2.0.5.4 in which problem is fixed.
Problem is affecting 10.2.0.5 to 10.2.0.5.3.
Cause
This is is a known and common problem hit in 10.2.0.5, investigated and corrected in unpublished Bug 7612454.

The problem was introduced in 10.2.0.5, by the fix of Bug:7523755.
This has been corrected in PSU 10.2.0.5.4 and 11.2.

解决方法

To quickest way to the solution of this problem is to apply PSU 10.2.0.5.4, Patch 12419392 or later.
All alternative solutions for this problem are listed below: 
•	Upgrade the database to 11.2.

OR
•	Apply 10.2.0.5.4 Patch Set Update (Patch 12419392) or later PSUs where bug is fixed. 
The available PSUs are mentioned in "10.2.0.5 Patch Set Updates - List of Fixes in each PSU" (Document 1337394.1)

OR
•	Apply interim Patch 7612454 on top of 10.2.0.5 (10.2.0.5.0-10.2.0.5.3):
o	For UNIX / Linux platforms apply Patch 7612454 available for download on MOS.
o	For Windows platforms apply Patch 3 or higher. 
Please check Document 342443.1 for latest patches available for Windows on top of 10.2.0.5.

这个错误在10.2.0.5上很容易发生，官方也没有给出发生这个错误的原因，以及如何改写相关sql，给出的方案是升级到10.2.0.5.4或者更高。这里可以看出升级需要慎重，可能导致原库有小部分sql不能正常执行。

lob类型数据转换为系统文件

Posted on by

1.插入一条blob数据

SQL> create directory ULTLOBDIR as '/home/oracle';

Directory created.

SQL> create table blobtest(col1 BLOB);

Table created.

SQL> declare
a_blob BLOB;
  2    3  bfile_name BFILE := BFILENAME('ULTLOBDIR','tt.txt.bak');
  4  begin
  5  insert into blobtest values (empty_blob())
  6  returning col1 into a_blob;
  7  dbms_lob.fileopen(bfile_name);
  8  dbms_lob.loadfromfile(a_blob, bfile_name, dbms_lob.getlength(bfile_name));
  9  dbms_lob.fileclose(bfile_name);
 10  commit;
 11  end;
 12  /

PL/SQL procedure successfully completed.

SQL> select dbms_lob.getlength(col1) from blobtest;

DBMS_LOB.GETLENGTH(COL1)
------------------------
                    4829

SQL> !pwd
/home/oracle

SQL> !ls -l tt.txt.bak
-rw-r--r-- 1 oracle oinstall 4829 03-19 17:26 tt.txt.bak

2.创建存储过程

CREATE OR REPLACE PROCEDURE RETRIEVE_LOB_TO_FILE(TEMP_BLOB IN BLOB,
                                                 FILE_PATH IN VARCHAR2,
                                                 FILE_NAME IN VARCHAR2) IS
  DATA_BUFFER   RAW(32767);
  POSITION      INTEGER := 1;
  FILEHANDLE    UTL_FILE.FILE_TYPE;
  ERROR_NUMBER  NUMBER;
  ERROR_MESSAGE VARCHAR2(100);
  BLOB_LENGTH   INTEGER;
  CHUNK_SIZE    BINARY_INTEGER := 32767;
BEGIN
  BLOB_LENGTH := DBMS_LOB.GETLENGTH(TEMP_BLOB);
  FILEHANDLE  := UTL_FILE.FOPEN(FILE_PATH, FILE_NAME, 'wb', 1024);
  WHILE POSITION < BLOB_LENGTH LOOP
    DBMS_LOB.READ(TEMP_BLOB, CHUNK_SIZE, POSITION, DATA_BUFFER);
    UTL_FILE.PUT_RAW(FILEHANDLE, DATA_BUFFER);
    POSITION    := POSITION + CHUNK_SIZE;
    DATA_BUFFER := NULL;
  END LOOP;
  UTL_FILE.FCLOSE(FILEHANDLE);
EXCEPTION
  WHEN OTHERS THEN
    BEGIN
      ERROR_NUMBER  := SQLCODE;
      ERROR_MESSAGE := SUBSTR(SQLERRM, 1, 100);
      DBMS_OUTPUT.PUT_LINE('Error #: ' || ERROR_NUMBER);
      DBMS_OUTPUT.PUT_LINE('Error Message: ' || ERROR_MESSAGE);
      UTL_FILE.FCLOSE_ALL;
    END;
END;
/

3.测试读取blob到系统

SQL> declare 
  2  tmp_blob blob default empty_blob(); 
  3  begin 
  4  dbms_lob.createtemporary(tmp_blob, true); 
  5  select col1 into tmp_blob from blobtest; 
  6  retrieve_lob_to_file (tmp_blob, 'ULTLOBDIR','xifenfei.txt'); 
  7  end;
  8  /

PL/SQL procedure successfully completed.

SQL> !pwd
/home/oracle

SQL> !ls -l xifenfei.txt
-rw-r--r-- 1 oracle oinstall 4829 03-20 23:44 xifenfei.txt

坏块分类与检测

Posted on by

很多人都对oracle都知道oracle坏块有逻辑坏块和物理坏块之分，其实根据物理和逻辑坏块的分类，还可以继续分下去；对于坏块的检查，很多人知道物理和逻辑坏块使用dbv和rman检测，那其他种类的坏块该怎么办呢？这篇文章整理自MOS，给大家整理个分析坏块的思路，在后续文章中，会给出各种坏块的解决思路
