jmeter建立JDBC连接池时遇到“A Test is currently running,stop or shutdown test to execute this command”

1.显示如下图，打开日志可以看到：Variable Name must not be empty for element:JDBC Connection Configuration，即JDBC Connection Configuration连接设置中Variable Name不能为空。

2.设置JDBC Connection Configuration中的Variable Name for created pool，需要“保存”，再运行一次脚本，问题即可解决
