DB2 V9.7 Workgroup打上FixPack 3a实现支持64G内存

1、DB29.7支持64GB内存的版本有哪些？ 企业版和高级企业版肯定支持，工作组版本呢？有条件的支持！但是需要Fix Pack 3a。否则无法支持64G，即使支持了64GB后超出部分依然不支持。

    例如，您可以将 DB2 Workgroup 安装到具有 128 GB RAM 的服务器上，但是该软件只能用 64GB 的 RAM。

注意：要利用新的 64 GB 的限制，需要用到 DB2 9.7 Fix Pack 3a。Fix Pack 3a 之前的版本的内存限制为 16 GB。如果无法获得 DB2 9.7 Fix Pack 3a 并需要利用这个新的 RAM 限制，请联系 IBM 代表。

 

2、无论你的内存有多大，都要设置虚拟内存。即使我的PC已经配置了至强E3 1230的CPU,DDR3 1600规格的16GB内存，在处理DB2的时候，由于DB2要求的缘故，我依然需要将虚拟内存进行分配，分配为32768M。

     否则在进行某些数据库操作时，会报存储器资源不足的错误。
