Problems trying to add an artifact to Rational Team Concert

I've installed the RTC Client 3.0.1 to RDz 8.0.2. I want now to add an artifact from a zOS Project to RTC and have followed the steps in http://publib.boulder.ibm.com/infocenter/clmhelp/v3r0m1/topic/com.ibm.rational.rtc.rdz.doc/topics/rdzrtcz_int_use.html. But I don't see the "Share members as zFiles". Is there any other possibility to add the artifact?

I assume you already installed "IBM Rational Team Concert Integration 3.0.1". If so, the option should be available under the context menu of z/OS Project navigator "zComponent > Share Members as zFiles..."

Well, that is a good question. I've installed the RTC 3.0.1 client both via Installation Manager (update of 3.0) and via Web-Installer. But I don't see any "IBM Rational Team Concert Integration 3.0.1", only the normal client.

The IBM article "Installing Rational Team Concert on Rational Developer for System z" says that I have to use first the Rational Team Concert launchpad, installing the RTC client into the same package group as the Rational Developer for System z client, and then open the Installation Manager. But the launchpad has already opened the IM once, so I'm not sure what I should expect to see the second time I open it. In any case, I haven't found any "RTC Integration", nor see I "zComponent" in the z/Os Project navigator.

How must I install the RTC client?

Is it absolutely necessary to install the file agent RSE miner in order to have the possibility to add artifacts to RTC?
