GBase 8t / informix 实例自动初始化脚本
大家好
很多小伙伴反映 GBase 8t的初始化数据库实例太繁琐了，很难快速上手。针对初学者的需求，最近写了一个 GBase 8t / informix 实例自动初始化实例脚本，请大家测试使用。有问题可以反馈给我。
再也不用安装数据库时选择自动创建实例了。本脚本采用交互式工作方式，提供初始化实例时的常用选项，并根据主机CPU/内存配置自动给出默认值建议。数据空间为自动扩展模式。对于初学者来说，可以一路按回车键选择默认值完成数据库的初始化，并获得较好的性能。
脚本是短时间内完成的，健壮性还比较差，所以请大家多多测试。
脚本会使用默认字符集建立gbasedb的数据库，并给出JDBC连接方式。
下面是我全使用默认值建立实例的过程:
[informix@localhost tmp]$ sh GBaseInit.sh
