大家好，请教各位一个关于cognos cube的问题，多谢了。
我有一个cube，其中的数据很多，是每日增量更新的，现在的大小有4.35GB，之前一直正常，突然从上周开始就报这个“系统内存不足”的错误了，
我google了一下，找到了下面两个解决方案
1.官方的
http://www-01.ibm.com/support/docview.wss?uid=swg213433452.论坛的
http://www.cognoschina.net/club/thread-24586-1-1.html就是下面的方法：
一个方法是增加读取cube的缓存大小，一个是清空cognos的临时文件。
具体：
1,打开cognos administration-->配置--->数据源连接--->单击选择你需要的数据源--->设置属性--->连接--->编辑连接字符串(铅笔符号)--->读取高速缓存大小(填写一个足够大的值，这个因为服务器不一所以不一)-->确定
2，删除cognos bin目录下的dmp临时文件
重启。
