今天发现SAP As Java 开发机无法启动，根据 Note 2542513 处理该问题并记录。
今天发现SAP EP+BPM服务器不能正常启动，jstart.exe进程显示 some process running 的黄灯状态。重启也不管用。到SAP官网 https://wiki.scn.sap.com/wiki/display/ASJAVA/%28JAVA%29+Application+Server+Java+Troubleshooting 里面找到Startup，点击 Starting AS Java cluster/instance 去看看到底发生了什么。
匹配到 Central services instance green; Java instance yellow 的情况。
匹配到 Internet Communication Manager (ICM) Running 的情况。
匹配到 server process Stopped 的情况。
匹配到 AS Java exit code 为 2150 的情况。
建议查看 server process log files (start with std_serverX.out files )，果然找到 /usr/sap/<SID>/J00/work/std_server0.out 文件。里面报错内容为

--------------------------------------------------------------------------------再到SAP官网搜索 Initialization of destination UMEBackendConnection failed ，找到note 2542513 ，按图索骥找到 AS Java 的配置工具，Configurations - Destinations - RFC - Propertysheet UMEBackendConnection ，于是逐项检查，最终发现是 jco.client.user 账号 SAPJSF_FMD 过期了。重新设置有效期即可解决问题。
