通过IOM(“Integrated Object Model” )服务器,没有必要使SAS安装在本地系统,通过Management Console和Enterprise Guide工具可以完美的连接到远端的SAS主机上
需要注意的是IOM服务器并不是代表一个具体的服务器,在SAS IT中,有下面4中类型的IOM服务器
Metadata 服务器 – 存储和管理元数据库,包含哪些SAS服务器、库、和存储过程可用
工作空间服务器 – 维护SAS程序环境;
存储过程服务器 – 运行 “canned” SAS程序
OLAP服务器 – 驱动CUBE数据到SAS Enterprise Guide或者其它OLAP客户端
工作空间服务器有下面3中类型
JAVA客户端连接到IOM服务器使用JAVA-IOM桥
WIN客户端连接到IOM服务器使用COM/DCOM技术,
WIN客户端可以连接到运行在UNXI上的IOM服务器,通过使用COM-IOM桥
对于WIN应用,IOM支持ADO通过OLEDB访问SAS数据
对应JAVA,JDBC2.0访问是被支持的
工作空间服务器包含下面接口
工作空间Workspace – SAS会话
语言服务Language Service –提交SAS DATA步和过程步,接收LOG和LIST输出,运行存储过程
数据服务Data Service – 管理SAS库
文件服务File Service – 管理文件标识
实用工具Utilities – formats, options, result packages, host system information
存储过程服务器
用于存放存储过程,其结果可以被WEB(Information Delivery Portal,BI WEB服务)、OFFICE(OFFICE插件)或者Enterprise Guide 3.0使用
假设在SAS服务器上存在下面文件
C:\temp>type IOMTest.sas
%let cond=;
*ProcessBody;
proc print data=sashelp.class;
title "Test Stored Process";
where &cond;
run;

JAVA客户端
编译时使用下面命令
javac -classpath ".:C:/Program Files/SAS/SAS 9.1/core/sasmisc/sas.svc.connection.jar" IOMTest.java
sas.svc.connection.jar文件位于 C:\Program Files\SAS\SAS 9.1\core\sasmisc 下
