Please show a complete piece of code. There is a chance you are missing some lines which could cause the problems you are having.

You could set the param first after starting roscore.

rosparam set filename test
rosrun my_package my_node

global nodehandle setting parameter can use rosrun commandline .private nodehandle not.

Emmm, you may add node_name before the filename, like "rosparam set node_name/filename test"

If filename_ is an std::string then:

rosrun my_package my_node _filename:="test"
