删除Oracle数据文件/临时文件

Posted on by

有些时候，想删除一个数据文件(临时文件),在10g之前的版本，要删除一个数据文件，必须删除该数据文件所属的表空间(特殊处理方法除外)。不太懂数据库的朋友直接os级别删除数据文件，导致数据库不能正常启动;稍微等点数据库的朋友，会先offline数据文件，然后os级别删除，但是这条数据文件的记录还保留在数据字典中，不爽(特殊处理办法见:清除离线数据文件记录)。在10g及其以后版本中，oracle提供了alter tablespace talbespace_name drop datafile/tempfile path/file_id进行删除某个数据文件

一、删除数据文件

三、注意事项
1、Oracle Database 10g Release 2及其以上版本
2、删除数据文件从数据库和系统
3、数据文件必须为空
4、数据文件不是对应表空间的最后一个
5、不能删除只读表空间中数据文件
6、不能删除system中数据文件
7、不能删除本地管理的offline表空间数据文件

TNS-12525 TNS-12535 TNS-12606

一、发现TNS-12525错误
检查公司服务器listener日志中周期性发现如下错误提示：

08-DEC-2011 02:25:34 * (CONNECT_DATA=(SID=ora9i)) * (ADDRESS=(PROTOCOL=tcp)(HOST=211.155.236.234)(PORT=4877)) * establish * ora9i * 0
08-DEC-2011 02:25:35 * (CONNECT_DATA=(SID=ora9i)) * (ADDRESS=(PROTOCOL=tcp)(HOST=211.155.236.234)(PORT=4879)) * establish * ora9i * 0
08-DEC-2011 02:25:43 * <unknown connect data> * (ADDRESS=(PROTOCOL=tcp)(HOST=211.155.236.234)(PORT=2486)) * establish * <unknown sid> * 12525
TNS-12525: TNS:listener has not received client's request in time allowed
 TNS-12535: TNS:operation timed out
  TNS-12606: TNS: Application timeout occurred
08-DEC-2011 02:26:02 * <unknown connect data> * (ADDRESS=(PROTOCOL=tcp)(HOST=211.155.236.234)(PORT=4876)) * establish * <unknown sid> * 12525
TNS-12525: TNS:listener has not received client's request in time allowed
 TNS-12535: TNS:operation timed out
  TNS-12606: TNS: Application timeout occurred

继续检查日志发现，只有211.155.236.234是外网ip，其他都是通过内网ip访问，都未报类此错误。初步怀疑是公司和运营商网络之间的防火墙导致

二、数据库版本

SQL> select * from v$version;

BANNER
----------------------------------------------------------------
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 10.2.0.4.0 - Production
CORE    10.2.0.4.0      Production
TNS for Linux: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production

三、MOS说明

Symptoms
At regular intervals (every three hours), you see new connections rejected with TNS-12525 "listener has not received client's request in time allowed".
The listener log shows the following error stack :
10-APR-2008 17:39:15 * <unknown connect data> * (ADDRESS=(PROTOCOL=tcp)(HOST=10.221.50.31)(PORT=4184)) * establish * <unknown sid> * 12525 
  TNS-12525: TNS:listener has not received client's request in time allowed 
    TNS-12535: TNS:operation timed out 
      TNS-12606: TNS: Application timeout occurred

At the same time the firewall log reports :
"TCP packet out of state: First packet isn't SYN; tcp_flags: PUSH-ACK"

Wireshark (Ethereal) traces show the TCP 3-way handshake never completes for those connections.

Changes
Value of idle timer was recently changed at firewall level.

Cause
Firewall closes ports not allowing the 3-way handshake to complete at TCP level.

Solution
Increase the firewall's idle timeout interval.

New Connections Intermittently Rejected with TNS-12525

2、alert日志文件

二、查询是损坏日志组

SQL> col member for a35
SQL> select a.group#,a.status,b.member from v$log a,v$logfile b 
   2 where a.group#=b.group#;

    GROUP# STATUS           MEMBER
---------- ---------------- -----------------------------------
         3 CURRENT          R:\ORADATA\HZYL\REDO03.LOG
         2 INACTIVE         R:\ORADATA\HZYL\REDO02.LOG
         1 INACTIVE         R:\ORADATA\HZYL\REDO01.LOG

确定是因为断电导致当前redo 损坏，需要使用隐含参数+不完全恢复处理(经验)

三、不完全恢复

SQL> recover database until cancel;

ORA-01194: 文件 1 需要更多的恢复来保持一致性
ORA-01110: 数据文件 1: 'R:\ORADATA\HZYL\SYSTEM01.DBF'

四、启用隐含参数，尝试打开数据库

SQL> create pfile='d:/1.txt' from spfile;

文件已创建。

利用impdp结合network_link+FLASHBACK_TIME初始化ogg同步数据

Posted on by

部署ogg，需要两边初始化数据，但是因为业务不能停止。所以考虑到使用ogg init功能或者impdp。考虑到数据量比较大，自己对ogg init不是很有信心，所以选择了使用impdp结合network_link+FLASHBACK_TIME处理
一、处理思路
1、选择时间点(尚未达到时间点)
选择一个时间点，用于重设ogg同步时间点，impdp导入时间点
要求:ogg尚未加载到该时间点(在该时间点之前停止ogg相关ext/pump/replicat进程)

2、开始导入指定时间点数据(该时间点已经达到后)

[oracle@srtcreen OGG]$ impdp srt_creen/a69UiBOB1gk directory=DATA_PUMP_DIR network_link=OGG_TYKF REMAP_SCHEMA=CSCNEW:SRT_CREEN REMAP_TABLESPACE=CSC_TAB_1:SRTCREEN tables=CSCNEW.TAB_CS_USER,CSCNEW.TAB_CS_QUEUES,CSCNEW.TAB_CS_CALL_PICKUP,CSCNEW.TAB_CS_CALL_COMING,CSCNEW.TAB_CS_CALLLOG FLASHBACK_TIME=\"to_timestamp\(\'2011-12-06 13:03:00\',\'yyyy-mm-dd hh24:mi:ss\'\)\"

3、重设同步时间点，开启进程

alter ext_1,begin 2011-12-06 13:03:00
alter ext_2,begin 2011-12-06 13:03:00
alter ext_3,begin 2011-12-06 13:03:00
alter ext_4,begin 2011-12-06 13:03:00

alter p_4,begin 2011-12-06 13:03:00
alter p_5,begin 2011-12-06 13:03:00
start *

alter r_1,begin 2011-12-06 13:03:00
alter r_2,begin 2011-12-06 13:03:00
alter r_3,begin 2011-12-06 13:03:00
alter r_4,begin 2011-12-06 13:03:00
alter r_5,begin 2011-12-06 13:03:00
start *

4、验证同步情况

V$PWFILE_USERS和密码文件关系(续)

1、验证密码文件已经修改

Grant succeeded.

2、查看基表

SQL> col owner for a20
SQL> col object_name for a30
SQL> SELECT owner,object_name,object_type FROM DBA_objects WHERE object_NAME ='V$PWFILE_USERS';

00002B9563678690          2          1 XFF01               0          0          0          0

从这里可以看出V$PWFILE_USERS视图的基表是x$kzsrt，这里和我们查看的密码文件一样，这些记录都存在，而是在密码文件中有不被strings显示的字符表示了账号是否启用，x$kzsrt.valid用1和0标示
