Joe,

The particular programming group I'm in is responsible for something on the order of a thousand source members, a small portion of our total system. A single filter with all of them takes 5 to 10 minutes to refresh with our box, and even without refreshing takes about 15 seconds to expand on my 2 GHz Core 2 Duo - I built the filter once to try it, and decided it was more trouble than it's worth, since I didn't know a way to position within the filter (in table view) that was as quick as the positioning dialog in PDM. Since there are often several possibilities for member name prefixes for a given function, I often have to try 2 or 3 times to find what I'm looking for. (Yeah, the naming conventions are old and terrible - can't do much about that at the moment.) PDM is very quick for that; I can't say the same for my multiple attempts at making filters that will get me to what I want.

Have you used RSE against a very large system? Are there tricks I'm not seeing for how to make the access faster? An unfiltered drill-down into our production source library, just to see the 20 or so objects in it, takes between 15 minutes and half an hour. Drilling into the QRPGLESRC in that library takes longer than that. WRKOBJPDM on that library and WRKMBRPDM on that file take a second or two.

This is something that really needs to be taken up with IBM. If they want people to move to the tool, then they need to fix this particular issue. It's a one-time fix; they need to write the appropriate APIs to do it. It may require PTFs, but it's pretty important. But honestly, I've NEVER seen a drill down take a half an hour. You may be the endpoint condition, but that's still crazy. Is it possible your QZRCSRVS jobs are running in a limited memory pool?

How often do I need to do it? Sometimes I go a week without needing it, other times I use it repeatedly in the same day - often with my boss or some other programmer standing over me. How do I justify to them taking 20 seconds to 20 minutes using RSE to do something that they know they can do in 2 seconds using PDM? It isn't so bad looking it up in PDM, Alt-Tabbing to WDSCi, and doing a Ctrl-Shift-A to open it - they can see the advantages of the color coding, outline view, and search functions. It's also easy to show the advantages of RSE filters over the development libraries - it's just during the research and analysis phase when we have to look at the production stuff that I get frustrated.

So, suggestions?

I'm going to do some of this myself. I'm going to create a source file with 1000 members and do some testing here just to see what happens. I'll get back to you.
