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

Within one week you will need a more recent DUL version for this os
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

DUL: FATAL Error: File OBJ.dat, line 22079: identifier too long

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.
