The original case by Juergen touches the main shortcoming of IBM's STEPLIB-stance.
There are cases when putting steplib(s) in linklist simply do not work! And where the alternative of putting it in the logon procedures is working nearly as bad. I have several times seen those cases luckily (= allowed by management) been solved by dynamic steplib functions from outside IBM. This happens when You must use conflicting software or software versions. One such case was when we were upgrading DB2 and during that period was the different test/development DB2 systems on different release levels. Another case was when we had different software (in the TSO development environments) that relied on the same set of "SAS/C" modules for I/O and other things - but of different releases of these modules. (At least one of those SW was IBM's.) And other cases. This experience coupled by some recent contacts with development labs at IBM give me the impression that IBM lacks contact with "the reality" out here... ;) Regards, Thomas Berg _________________________________________ Thomas Berg Specialist A M SWEDBANK > -----Ursprungligt meddelande----- > Från: IBM Mainframe Discussion List [mailto:[email protected]] För > Juergen Keller > Skickat: den 25 januari 2012 09:51 > Till: [email protected] > Ämne: Re: PDSE > > Hello all, > thank you for your updates and hints.
