Oracle dul支持Oracle 12.2(12c)

发表于 2017 年 2 月 22 日 由 惜分飞

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)

[oracle@localhost dul]$ ./dul

DUL: Warning: Compatible is set to 11 Values can be 6|7|8|9|10|11|12

在12.2的版本中运行dul结果如下

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
dul-error

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
dul-clear
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.

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

最新版Oracle dul支持Oracle 7.2.3

发表于 2015 年 11 月 24 日 由 惜分飞

网上有朋友发过来了oracle 7.2.3的数据文件说dul新版本无法支持,我进行测试,可以正常使用dul挖oracle 7.2.3版本oracle.再次实测刷新dul对于oracle老版本支持记录(以前实测dul支持oracle 8.0:DUL10直接支持ORACLE 8.0,DUL挖ORACLE 8.0数据库).根据dul官方说法从oracle 6 及其以后版本都支持
最新版dul(10.2.0.6.11)支持oracle 7.2.3
