A Client's VW taking up to 2 minutes to start each morning ...
 
|
I have a client who's VW normally takes about 3 seconds to start and show
its first small window. Running from Windows-XP SP2, VW 7.4 However, after being logged off for a time it takes about 2 minutes. My first thoughts were - disks turned off - lots of other non-VW things running occupying memory but this does not appear to be the case. Here are some details - the saved image has a single minimized window - on startup the window shows in the task bar after a couple of seconds - I cannot interrupt during the 2 minutes of nothing happening, cannot use ctrl/y, shift+ctrl/y or ctrl/\ - I have an optional halt at the start of any of our code that rungs, triggerred by holding SHIFT -- it kicks in AFTER the 2minutes I cannot determine what is occurring if anything during that 2min period -- anyone have any thoughts on this?? -- Dennis Smith +1 416.798.7948 Cherniak Software Development Corporation Fax: +1 416.798.0948 509-2001 Sheppard Avenue East [hidden email] Toronto, ON M2J 4Z8 sip:[hidden email] Canada http://www.CherniakSoftware.com Entrance off Yorkland Blvd south of Sheppard Ave east of the DVP |

Use a debug VM and the -o10s VM parameter, or attach a debugger when starting?
One possibility is that the app has something which tries to initialize something network-related at startup, and that has problems with name resolution. We had a similar problem with VW SOAP earlier (although I didn't notice if the startup was quicker later in the day), but that was fixed in 7.3.1 (AR 48892: [core] consider lazy initialization of GenericProtocol class>>hostAddress).

This way you can see when the two minutes of nothing happen.

That worked nicely -- but there was so much happening that it all
scrolled off the little window.
Is there a way to capture the text in a file???

Click the icon at
the top left of the command prompt window, and set the Properties | Layout |
Screen Buffer size height to 1000. You can choose whether this change is global
for all command prompts, or only for prompts running the same command - either
should work. Next time you run the test, you'll be able to scroll
back.
