hostname配置不切当导致TNS-12542错误

发表于 2011 年 12 月 15 日由惜分飞

一、监听异常现象

[oracle@gongantest ~]$ lsnrctl start

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.11.60)(PORT = 1521))
    )
  )

二、相关网络配置

[oracle@gongantest ~]$ ping gongantest -c 2

[oracle@gongantest ~]$ more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.

[oracle@gongantest network-scripts]$ more /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=gongantest
GATEWAY=192.168.8.1

三、解决问题

[oracle@gongantest ~]$ more /opt/oracle/product/10.2.0/db_1/network/admin/listener.ora
# listener.ora Network Configuration File: /opt/oracle/product/10.2.0/db_1/network/admin/listener.ora

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /opt/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.11.60)(PORT = 1521))
    )
  )



[oracle@gongantest etc]$ lsnrctl start

四、补充说明
如果把hostname配置在hosts中的127.0.0.1项,那么如果在监听中使用了hostname,再配置一个host监听该机器的ip地址(非127.0.0.1),那么会报文章开头的错误,解决方法有两种:
1、监听中全部采用ip地址
2、在hosts中配置hostname对应ip地址(非127.0.0.1)

开发那边有台Linux 32位服务器因为网卡问题，准备把数据库迁移到一台新服务器(Linux 64)上。因为是开发环境(对稳定性要求不是非常高，停机时间几乎没有要求)，还有我比较懒，准备两边安装相同版本，打上相同的补丁，然后直接拷贝datafile/redo/controlfile/spfile的方法完成数据文件迁移
一、源端信息

--系统信息
[oracle@localhost ~]$ uname -a
Linux localhost.localdomain 2.6.18-194.el5PAE #1 SMP Tue Mar 16 22:00:21 EDT 2010 i686 i686 i386 GNU/Linux

--数据库信息
[oracle@localhost ~]$ sqlplus / as sysdba

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

二、目标端信息

--操作系统信息
[oracle@gongantest ~]$ uname -a

三、迁移数据库
1.修改目标库ORACLE_SID变量等环境变量
2.目标库建立相关目录(参考源库)
3.使用shutdown immediate关闭源库
4.拷贝spfile和oradata中文件

四、启动目标端数据库

[oracle@gongantest gaxt]$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.4.0 - Production on Thu Dec 15 12:46:19 2011

Copyright (c) 1982, 2007, Oracle.  All Rights Reserved.

五、收集系统统计信息

SQL> exec dbms_stats.delete_system_stats();
BEGIN dbms_stats.delete_system_stats(); END;

六、重新编译对象

SQL> shutdown immediate;
SQL> startup upgrade;
SQL> @?/rdbms/admin/utlirp.sql
SQL> @?/rdbms/admin/utlrp.sql
SQL> shutdown immediate;
SQL> startup;

七、出现ORA-07445[_intel_fast_memcpy.J()+250]错误

                        DIMENSION AWMDKEY FROM sys.awmd!AWMDKEY_CAT'); 
   end;

查看MOS，发现 Oracle OLAP AWs(Analytical Workspace)在迁移过程中没有正确处理导致，不过该功能该库中没有使用到，直接忽略

八、查询组件是否都正常

九、收集系统信息

修改clob字段并插入新表

发表于 2011 年 12 月 14 日由惜分飞

最近开发有个需求，需要替换一张表的clob字段中的某些字符串，然后插入的一张新表中，我查询了一些资料，利用function结合匿名块模拟实现
0、数据库版本

SQL> select * from v$version;

BANNER
-----------------------------------------------------------------------

Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
PL/SQL Release 11.2.0.1.0 - Production
CORE    11.2.0.1.0      Production
TNS for 32-bit Windows: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production

1、创建替换clob中字符串函数

create or replace function replaceClob_new (
srcClob IN CLOB,
replaceStr IN VARCHAR2,
replaceWith IN VARCHAR2
--newClob OUT CLOB
) RETURN CLOB
IS

vBuffer    VARCHAR2 (32767);
l_amount   BINARY_INTEGER := 32767;
l_pos      PLS_INTEGER := 1;
l_clob_len PLS_INTEGER;
newClob  CLOB;

BEGIN
   newClob  := EMPTY_CLOB;
  -- initalize the new clob
 dbms_lob.createtemporary(newClob,TRUE);
 l_clob_len := dbms_lob.getlength(srcClob);
 WHILE l_pos < l_clob_len
  LOOP
    dbms_lob.read(srcClob, l_amount, l_pos, vBuffer);
    IF vBuffer IS NOT NULL THEN
      -- replace the text
      vBuffer := replace(vBuffer, replaceStr, replaceWith);
      -- write it to the new clob
      dbms_lob.writeappend(newClob, LENGTH(vBuffer), vBuffer);
    END IF;
    l_pos := l_pos + l_amount;
  END LOOP;
  RETURN newclob;
  
 EXCEPTION
  WHEN OTHERS THEN
    RAISE;
END;

2、创建原表，并测试该函数

SQL> CREATE TABLE t_clob(ID NUMBER,clob_xff CLOB);
 
Table created

--手工通过plsql dev插入一些数据（大于4000）

SQL> select dbms_lob.getlength(clob_xff) from t_clob;
 
DBMS_LOB.GETLENGTH(CLOB_XFF)
----------------------------
                        4856

SQL> select dbms_lob.getlength(replaceClob_new(clob_xff,'function','1')) from t_clob;
 
DBMS_LOB.GETLENGTH(REPLACECLOB
------------------------------
                          4814

SQL> set long 50
SQL> select clob_xff from t_clob where id=1;

CLOB_XFF
--------------------------------------------------
create or replace function replaceClob_new (
srcCl

SQL> select replaceClob_new(clob_xff,'function','1')
  2  from t_clob where id=1;

REPLACECLOB_NEW(CLOB_XFF,'FUNCTION','1')
--------------------------------------------------
create or replace 1 replaceClob_new (
srcClob IN C

3、编写匿名块实现插入功能

DECLARE
  A_CLOB CLOB;
  R_CLOB CLOB;
  VSTRT  NUMBER(4);
BEGIN
--否则会在新表的clob字段头部会有空格
  VSTRT := 1;
  SELECT REPLACECLOB_NEW(CLOB_XFF, 'function', 'xifenfei')
    INTO R_CLOB
    FROM T_CLOB
   WHERE ID = 1;
  INSERT INTO T_CLOB_NEW
    (ID, CLOB_XFF)
  VALUES
    (1, EMPTY_CLOB())
  RETURNING CLOB_XFF INTO A_CLOB;
  DBMS_LOB.WRITE(A_CLOB, DBMS_LOB.GETLENGTH(R_CLOB), VSTRT, R_CLOB);
  COMMIT;
END;

4、测试匿名块功能

SQL> set long 50
SQL> select clob_xff from t_clob where id=1;

CLOB_XFF
--------------------------------------------------
create or replace function replaceClob_new (
srcCl

SQL> select clob_xff from t_clob_new where id=1;

CLOB_XFF
--------------------------------------------------
create or replace xifenfei replaceClob_new (
srcCl
