Quickly setup a stream environment.

原创 Oracle 作者:foreverlee 时间:2008-12-30 16:46:02 0 删除 编辑
This article is intended to quickly setup a stream environment for playing in which the schema HR in primary side will be in sync with the one in target side.[@more@]

Primary Side. O01DMS0
Target Side. O01LEE3
