TIBCO Designer Panel too small

Recently I ran into some rather trivial problem which isn’t really addressed by the TIBCO Designer. I had a process which wouldn’t fit into the Design Panel. There was just not enough space on the canvas to fit in the actual flow.
After asking around I came to the conclusion that every designer (from different colleges I work with) had a different resolution for the Design canvas. Nobody knew any kind of property where you can set this resolution, so I began searching around.
The designer uses basically 2 Folder for its configs. One is the installation folder with the designer.tra (already explored this one). The other one is the .TIBCO folder in your user home directory. In that folder there exists a file with the name “Designer5.prefs”.
The content of this file consists mainly of position data of the various dialogs. Further to that it includes all the values which you can set through the designer preferences window. Back to the actual topic, I found the following two values:


These values represent the default size which the Designer allocated for its canvas. As you can see the default is pretty small on this one. I also found installations where both values where ten times larger then this. So far I found no performance penalty to this.
The only pattern I found is that newer installation had smaller values as default. Where this value comes from and how it is determined stays unclear to me.

One other thing I found during my research. If the panel is to small for the current process you can drag one activity right next to the border and then start to move it via keyboard (‘Shift + Cursor’). By doing so you drag the icon out of the canvas, but the position will be updated internally. After that you just need to refresh the process view and voila you have expanded the canvas size. But this is just a quick and dirty work-around.

TIBCO Designer with external memory window

During Research for my last blog post I found an interesting feature of the designer. If the designer uses more than one gigabyte of heap memory, the display of the memory usage gets a bit fuzzy.
Obviously somebody at TIBCO forgot to round the value, so it would fit into this small section of the status bar.
Keeping that in mind I found a start parameter which allows you to start the designer with an external window which only displays the current memory load.
As you can see this is much more useful then the default.
To get this you just have to start the designer with the following command:

./designer -memory

I wonder how much more (undocumented) functionality is hidden in the designer.

improve TIBCO Designer tester performance under linux

I’m using the TIBCO designer for quite a while now. Before using it in a debian environment I developed all TIBCO related stuff in Windows XP. Now with the switch to linux there came quite a shift in user experience. One thing that really annoyed me was the slow performance of the designer debugger.
So I started some measurements with a simple test process. The test process creates a simple list of all files (2000 items) in one folder and then iterates over every entry. Here is what I got:

Windows XP: 194sec
Windows XP (minimized): 6sec
Gnome: 470sec
Gnome (minimized): 4sec

All this data was gathered with the same default installation of a TIBCO designer 5.6 with the default java runtime. The configs were all left untouched. So now I tried to find something to improve that behavior. I first concentrated on how to influence the jvm.
After a bit of research in the TIBCO direction a found the following value in the tra-file which allows the user to pass parameters directly to the jvm:

With that information I tried several parameters suggested by google. After a few tries I came to this one:


What Sun says about it isn’t really clear to me but it helps drastically to improve performance. Back to my original test I came up with the following timings:

Gnome (pmoffscreen=false): 75sec
Gnome (pmoffscreen=false): 5sec

As you can see it actually surpasses the Windows installation. That was a result I didn’t actually expect. Till now I found no drawback to this solution.
Just for the sake of completeness here my full config line of the designer.tra -Xmx3072M -Xms1536M -XX:+AggressiveOpts -XX:-UseParallelGC -XX:-UseConcMarkSweepGC -XX:MaxPermSize=512M -XX:+UseFastAccessorMethods -Xverify:none -Dsun.java2d.pmoffscreen=false
