我尝试使用 SchemaCrawler 从 Oracle 数据库中获取 MPD。该工具生成一个点文件，然后使用点生成图形。

但是一个小时后，处理仍然没有完成，所以我尝试使用以下命令在我的点文件上启动自己的点：

dot -v -Tpng schemacrawler.7007049984130928063.dot > graph.png

在下面的点文件中，我尝试减少边缘的数量，大约 60 个边缘持续 2 分钟，超过它永远不会完成。=> 文件： http: //pastebin.com/Wvup5NTF

我得到以下跟踪：

C:\dev\softs\schemacrawler-oracle-10.08.02>dot -v -Tpng schemacrawler.7007049984130928063.dot > graph.png

dot - graphviz version 2.30.1 (20130214.1330)

libdir = "C:\dev\softs\graphviz"

Activated plugin library: gvplugin_pango.dll

Using textlayout: textlayout:cairo

Using render: cairo:cairo

Using device: png:cairo:cairo

Activated plugin library: gvplugin_dot_layout.dll

Using layout: dot:dot_layout

The plugin configuration file:...

network simplex:  28 nodes 80 edges maxiter=2147483647 balance=2

在那之后，什么都没有。有没有办法让它更快并且能够管理如此数量的节点和边缘（我认为这不是那么高）？

谢谢

尝试更新您的 Graphviz。我尝试了该文件，它对我来说效果很好。这是详细的输出：
