给你的rman备份集加上密码锁

数据的安全越来越重要,不是说你的生产库安全，你的数据就一定安全了，rman备份也是泄露数据的一个重要地方,如果别人拿到了你的备份集,一样等同入侵了你的生产库。为了rman备份的安全，最简单方式就是使用set encryption方式在rman备份过程中设置密码,需要版本为10.2及其以后企业版版,另外如果需要备份到带库只能使用oracle自己的osb(Oracle Secure Backup),注意rman只有backupset可以加密,copy无法进行加密

至此我们可以看到,最简单的rman加密备份和加密恢复测试完成,在使用set encryption加密后,如果不输入或者错误的输入密码无法使用备份集,从而确保了备份集的安全.

通过DBMS_CRYPTO包对表敏感字段进行加密

在安全越来越重视的近体，我们不少时候需要对数据库中的某个表的敏感列数据(银行卡,身份证号码,金额等)进行加密，方式数据泄密,在11.2.0.4中可以通过dbms_crypto包方式实现,增加oracle的加密效率,本文提供处理思路,其他可以根据需求尽情发挥

通过这里可以知道数据库在启动的过程中由于无法访问access$表从而出现ORA-00942错误,又是由于该sql是数据库内部调用因为出现ORA-00604错误.
出现该错误的原因是由于:BUG:12733463 – ORA-704, ORA-604 AND ORA-942 ON TABLE ACCESS$ DURING STARTUP
官方提供方法

1. Shutdown (abort) the instance and clean up any OS structures used by the instance.
    Eg: Ensure there is no shared memory, semaphores etc.. left lying around
2. Retry the startup.
3. If the error persists try and recover the database or recover from a backup.

10g dataguard 只读和应用归档互换脚本

在Oracle 11g中能够通过active dataguard特性实现备库只读而且同步应用日志,10g及其以前版本,在应用日志的时候库是不能把打开到read only模式,对于一些实时性要求不是特别高的应用,比如他们可以实现在白天只读,查询业务,晚上应用日志.如果人工每天做类似处理工作量太大,这里因为有朋友需要,基于win平台写了类似功能脚本,通过计划任务调用来实现白天只读,晚上应用日志的功能
数据库从应用归档模式转换为只读模式

--change_open.bat
sqlplus / as sysdba @C:\oracle\product\script\change_open.sql
--change_open.sql
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE cancel;
alter database open read only;
exit;

数据库从只读模式转换到应用归档模式

--change_mount.bat
sqlplus / as sysdba @C:\oracle\product\script\change_mount.sql
--change_mount.sql
shutdown immediate;
startup mount ;
alter system register;
alter system register;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT
LOGFILE DISCONNECT FROM SESSION;
conn sys/oracle@ntsy as sysdba
alter system set log_archive_dest_state=defer;
alter system set log_archive_dest_state=enable;
alter system switch logfile;
exit;

这里可以看出来，是由于执行触发器导致该问题,根据经验第一感觉很可能是logon之类的触发器导致。

查询触发器

SQL> select trigger_name,trigger_type,OWNER from dba_triggers where owner='OP';
TRIGGER_NAME                   TRIGGER_TYPE     OWNER
------------------------------ ---------------- ------------------------------
LOGAD                          AFTER EVENT      OP
TR_TRACE_DDL                   AFTER EVENT      OP

只有这两个触发器是基于事件的,另外从名字和dba_source中确定

SQL> select text from dba_source where name='LOGAD';
TEXT
--------------------------------------------------------------------------------
TRIGGER "OP".logad after logon on database
begin
insert into logad values (SYS_CONTEXT('USERENV', 'SESSION_USER'), SYSDATE,SYS_CO
NTEXT('USERENV','IP_ADDRESS')) ;
end;
已选择6行。
SQL> select text from dba_source where name='TR_TRACE_DDL';
TEXT
--------------------------------------------------------------------------------
TRIGGER "OP".tr_trace_ddl
AFTER ddl
ON database
DECLARE
sql_text ora_name_list_t;
state_sql ddl$trace.ddl_sql%TYPE;
BEGIN
FOR i IN 1..ora_sql_txt(sql_text) LOOP
state_sql := state_sql||sql_text(i);
END LOOP;
TEXT
--------------------------------------------------------------------------------
INSERT INTO ddl$trace(login_user,audsid,machine,ipaddress,
schema_user,schema_object,ddl_time,ddl_sql)
VALUES(ora_login_user,userenv('SESSIONID'),sys_context('userenv','host'),
sys_context('userenv','ip_address'),ora_dict_obj_owner,ora_dict_obj_name,SYSDATE
,state_sql);
EXCEPTION
WHEN OTHERS THEN
-- sp_write_log('捕获DDL语句异常错误：'||SQLERRM);
null;
END tr_trace_ddl;

基本上确定LOGAD是登录触发器,tr_trace_ddl是记录ddl触发器,那现在问题应该出在LOGAD的触发器上.因为该触发器在备库上当有用户登录之时,他也会工作插入记录到logad表中,由于数据库是只读,因此就出现了类似ORA-01552错误

解决方法
在触发器中加判断数据库角色条件,当数据库为物理备库之时才执行dml操作

SQL> CREATE OR REPLACE TRIGGER "OP".logad
  2  AFTER LOGON on database
  3  declare
  4  db_role varchar2(30);

windows rman自动备份并传输到远程服务器处理方法

在linux中，要使用rman备份后传输到远程服务器上,可以选择ftp,scp,nfs等方式实现,在win主机上可以配置ftp或者共享实现.linux的解决方法已经很多,这里重点提供win上面实现rman备份且传输到远程服务器的解决方法,简单实现异地备份方法:
1.win配置共享目录，而且设置远程服务器有写权限,如果省事可以配置everyone有读写权限
2.创建相关备份目录,这里主要是rmanfile,rmanscript,rmanlog
3.编写rman备份脚本

CONFIGURE RETENTION POLICY TO REDUNDANCY = 7;
CONFIGURE DEVICE TYPE DISK PARALLELISM 4;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
backup  as compressed backupset database format 'E:\backup_db\rmanfile\full_%T_%U.rman';
sql 'alter system archive log current';
backup  as compressed backupset archivelog  all format 'E:\backup_db\rmanfile\arch_%T_%U.rman'  delete input;
DELETE noprompt OBSOLETE;
crosscheck backup;
delete noprompt expired backup;
backup  format 'E:\backup_db\rmanfile\ctl_%T_%U.rman' current controlfile;
backup spfile format 'E:\backup_db\rmanfile\spfile_%T_%U.rman' ;
exit;

4.调用rman备份脚本

rman target / cmdfile=E:\backup_db\scriptfile\backup_db.rman
log=E:\backup_db\logfile\rmanlog_%date:~0,4%%date:~5,2%%date:~8,2%.log

5.拷贝到远程脚本
需要注意是按照备份集中的日期作为标记来删除的，也就是说，一次备份最好不要跨天

copy /y e:\backup_db\rmanfile\*_%date:~0,4%%date:~5,2%%date:~8,2%_*.RMAN \\192.168.13.40\oracle_backup

6.删除远程服务器N天前备份脚本
需要注意是按照备份集中的日期作为标记来删除的，也就是说，一次备份最好不要跨天

@echo off
set DaysAgo=5
call :DateToDays %date:~0,4% %date:~5,2% %date:~8,2% PassDays
set /a PassDays-=%DaysAgo%
call :DaysToDate %PassDays% DstYear DstMonth DstDay

set /a z=14-mm,z/=12,y=yy+4800-z,m=mm+12*z-3,j=153*m+2

set /a dd=-dd+e+1,mm=-m/10,mm*=12,mm+=m+3,yy=b*100+d-4800+m/10
(if %mm% LSS 10 set mm=0%mm%)&(if %dd% LSS 10 set dd=0%dd%)
endlocal&set %2=%yy%&set %3=%mm%&set %4=%dd%&goto :EOF

7.配置计划任务,让定时执行相关脚本

升级数据库到10.2.0.5遭遇ORA-00918: column ambiguously defined

一个数据库从10201升级到10205之后,出现ORA-00918错误,查询mos发现在以前版本中是bug,Oracle好像在10205中把它修复了,结果就是以前应用的sql无法正常执行.这次升级的结果就是客户晚上3点联系开发商紧急修改程序。再次提醒：再小的系统数据库升级都需要做,功能测试,SPA测试,确保升级后功能和性能都正常.

执行报错ORA-00918
多个表JOIN连接,由于在select中的列未指定表名，而且该列在多个表中有，因此在10205中报ORA-00918错误，Oracle认为在以前的版本中是 Bug 5368296: SQL NOT GENERATING ORA-918 WHEN USING JOIN. 升级到10.2.0.5, 11.1.0.7 and 11.2.0.2版本，需要注意此类问题。修复bug没事,但是修复了之后导致系统需要修改sql才能够运行,确实让人很无语

在数据库出现莫名其妙问题不能启动之时,请注意主机时间,另外还有一例:记录一次ORA-00600[2252]故障解决

ORA-01157: cannot identify/lock data file导致表空间无法online

朋友和我聊到一个案例,一个表空间本来有一个数据文件(已经有大量数据进入),然后他加入7个数据文件,这个时候他发现他加多了文件,想删除这些数据文件,可是又不怎么懂数据库,直接offline 表空间,然后rm掉相关数据文件,最后表空间无法online.我对其场景进行了模拟恢复测试,使用bbed和dul对其进行恢复

模拟场景
表空间有一个数据文件,里面有数据,然后加入一个新数据文件,进入offline tbs,然后rm数据文件
offline表空间后,该表空间存在的数据文件也会offline

ORA-01110: data file 12: ‘/u01/oracle/ora9i/oradata/xifenfei02.dbf’
ORA-01251: Unknown File Header Version read for file number 12
这个主要是块号和块地址不一匹配,导致数据库无法识别

这个由于数据文件头的创建scn和控制文件以及file$中的记录不一致

ORA-01122: database file 12 failed verification check
ORA-01110: data file 12: ‘/u01/oracle/ora9i/oradata/xifenfei02.dbf’
ORA-01207: file is more recent than controlfile – old controlfile
这个由于正常数据文件online过,或者你构造文件头使用的scn大于需要构造文件在控制文件中记录的scn值

后续处理

这里证明,在表空间不能online的情况下,dul处理类似故障很轻松(但是需要重建表空间,bbed处理的从原理上可以不重建表空间),当然如果涉及的对象很多,而丢失的文件很少,可能bbed也不失为一种很不错的选择.
另外补充:如果表空间丢失的文件包含数据,也可以通过类似bbed和dul方法处理:bbed 让表空间online之后需要考虑跳过丢失文件;dul处理完全相同
