Oracle dul支持Oracle 12.2(12c)
随着oracle 12.2正式版的临近,通过最新版dul(Data UnLoader: 11.2.0.1.1)的测试,发现对于12c的版本支持依旧有问题,虽然作者在版本中较为明确的表示了支持12c但是测试效果不尽人意.
dul 11对oracle 12c的支持（Compatible参数表明支持12c)

这个报错DUL: FATAL Error: File OBJ.dat比较明显由于dul在加载obj$对象的时候有对象字符太长导致加载失败
这个是由于在oracle 12c中已经允许对象名/列名程度为128,而不是以前版本的30,从而引起了这个问题,虽然dul的作者已经在dict.ddl中做了限制,但是目前看尚未生效
特殊处理后的dul可以完美支持12c

这里是通过特殊处理之后dul才能够支持12c版本,期待作者在后续版本中完善相关工作,在恢复的经验中dul还是一大利器.
oracle dul 11 正式发布
千呼万唤oracle dul 11终于发布了,迫不及待的下载来测试,现在版本号为dul 11.2.0.0.1,目前只发布了for linux,其他版本估计要等等.期待该版本有引进新功能

在oracle 12c中对象名长度已经变为128,但是dul依旧不能支持列长度，既然作者已经在init.dul的Compatible参数曾增加了对12c的支持,那对这样明显的bug应该在不久的将来即可修复。当然这个问题,可以通过一些人工技巧绕过去
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

在bbed的恢复过程中出现以下常见错误:
ORA-01122: database file 12 failed verification check
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
ORA-01122: database file 12 failed verification check
ORA-01110: data file 12: ‘/u01/oracle/ora9i/oradata/xifenfei02.dbf’
ORA-01203: wrong incarnation of this file – wrong creation SCN
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

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
