我试图在Windows 7 64位安装Informatica的IDQ。我创建了一个bigfiles，但我仍然没有得到内容错误。我有甲骨文，和我用下面的查询来创建一个大的文件。
create BIGFILE TABLESPACE CMX_DATA
NOLOGGING
DATAFILE 'C:\oraclexe\app\oracle\oradata\XE\CMX_DATA1.dbf' SIZE 3000M REUSE
EXTENT MANAGEMENT LOCAL;
但我仍然得到一个ora_01658 unable to create INITIAL extent for segment错误。

该错误消息告诉您的表空间的名称：
ORA-01658：无法在SYSTEM表空间中创建段初步的程度，
安装试图创建在SYSTEM表空间的表空间。因此，它其实并不重要，你是如何分配空间给CMX_DATA，您的安装程序不使用它。
这是错误的：只有Oracle内部架构应写入SYSTEM表空间。一定有什么东西在Informatica的安装程序或IDQMRS用户定义的配置出错。你需要回去过步骤找到你需要指定目标表空间和纠正的地方。
