I would guess many people are using user defined activities in process flow. As do we when we do partner work. Wouldn't it be nice if you could change the icons for the user defined activities to better show what is being done in that activity? In some cases it might be, and it is quite simple to do.
First step is to create an iconset. You do this in the Global Explorer under icon sets. Here is an example of the completed dialog.
Next is to actually associate this iconset with the process flow activity. For mappings this can be done within the UI, but for process flow activities this is done via scripting:
OMB+> OMBALTER PROCESS_FLOW 'LOAD_ORCL' MODIFY ACTIVITY 'RUN_SIS_JOB' SET REFERENCE ICONSET 'STARANALYTICS'
Process Flow Activity RUN_SIS_JOB altered.
Process Flow LOAD_ORCL altered.
After this you get a wonderful icon reflecting the actual external job you are calling.
If you want to show separate icons on the mappings, here is how you do that. It is on the properties panel and it will change the icon in the design center.
Now of course you are wondering what Star Analytics is. Well, this is a company / product that allows you to re-integrate your Essbase data back into the relational data warehouse. It handles the extraction from Essbase, in this case into Oracle base tables. You then run the OWB mappings to load the data into the Oracle data warehouse. Quite cool if you need to integrate for example finance data back into the EDW.
