3737.0. "Source code for P.S.I V4.3" by WOTVAX::DENNISONE () Tue Feb 18 1997 09:03

    Does anyone have access to the source code for P.S.I. V4.3? A customer
    of ours (BT/Syntegra) are running this version of P.S.I. Analyzing
    crash dumps involving processes such as LES$ACP is difficult without
    having some idea of what the process was doing.
    
    Any help in locating any source code would be much appreciated.

3737.1	an academic exercise?	BULEAN::RMULAC.DVO.DEC.COM::S_WATTUM	Scott Wattum - FTAM/VT/OSAK Engineering	`Tue Feb 18 1997 13:42`	10
	What use is there in analyzing a crash dump on a product that is no longer supported? Even if you had the source code and were able to identify the problem, engineering won't fix the problem, since the product is no longer supported. In any event, you might try one of the CSC's - they used to get copies of source listings for many of the networking products (though I don't remember if P.S.I. was one of them). --Scott
3737.2	Upgrade	MARVIN::SIMS	Andrew Sims, IPEG Reading.	`Tue Feb 18 1997 18:20`	14
	The source code for both P.S.I. V4.3 and LES V2.0 have now been archived. Even if the source code or listing were still really available analysing a dump without having a some knowledge of LES concepts would be very difficult and time consuming. If you had found the problem then what, as the product is unsupported engineering will not provide a fix. Also because of the way LES loads the various images that make up the product, it this case P.S.I., you can not patch a image with the PATCH utility (to be precise you can as long as you do not us any patch areas). I really believe that your best course of action is to get the customer to upgrade to a DECnet/OSI. Andrew.
