最近公司服务器做迁移,原R3 PRE需要迁到另外的地方,迁移后一段时间内,需要两套PRE环境同时运行,过一段时间后才将传输路线切换到新的PRE。在切换前,要求新PRE环境也要正常同步发布请求,但传输路线只有一条,这需要在发原PRE时,同时手工发布新PRE,这样每次手工很麻烦(手工导入传输请求过程参考这篇文章)。本文就是来通过程序实现这种手工全过程,实现同步自动发布新PRE。实现过程也算简单,通过一台中间Java Web服务器进行传输请求的中转,将DEV上的传输请求文件下载后,上传到新PRE服务器上,然后在新PRE服务器上导入新的请求即可。这就需要在DEV上写个远程RFS接口,将需要传输的请求所对应的数据与配置文件下载下来;在新PRE上写个远程接口,将从DEV上下载下来的传输请求文件上传到新PRE服务器上,其后通过调用发布函数进行请求发布。代码涉及到三台机器:SAP DEV ——> Java Web中转服务器 ——> SAP PRE,之间采用JCO进行连接。最新的SAP JCO包请点击这里下载,Linux上So动态链接库以及Windows的Dll部署请百度
