What we see:D SMS,PDSE1,CONNECTIONS,DSN(library) returns open status of input for every PSF STC.D GRS,RES=(SYSDSN,library) returns nothing. Consistent for SCHEDxx NODSI. The PSF manual clearly states that DSI prevents other programs from updating resource libraries while PSF is active. It would be desirable to update a PDSE while DISP=SHR and DSI is set, without adversely impacting anyone. There is an exit to have PSF close an idle library, to be used in conjunction with DSI (if I'm reading the doc right). Bottom line is we were suprised about this PDSE behavior, and missed the documentation about it. Whether this feature is right or wrong is a whole 'nuther discussion. I appreciate everyone's input, and I intended to advise the original poster about a possible pitfall of converting to PDSEs.

Thats correct gil. A few IBM products run with NODSI intentionally. Looking the I&T, looks like PSF, VLF, DLF, FFST, RMF, JES2, JES3, *MASTER*, SMF, CAS I wouldn’t be changing them to DSI in SCHED00, as I am sure they are set that way for good reason. _____________________________________________________________________________________________________ Dave Jousma AVP | Manager, Systems Engineering Fifth Third Bank | 1830 East Paris Ave, SE | MD RSCB2H | Grand Rapids, MI 49546 616.653.8429 | fax: 616.653.2717 -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Paul Gilmartin Sent: Wednesday, October 23, 2019 10:07 PM To: [email protected] Subject: Re: PDS to PDSE conversion issues **CAUTION EXTERNAL EMAIL** **DO NOT open attachments or click on links from unknown senders or unexpected emails** On Wed, 23 Oct 2019 20:37:52 +0000, Jousma, David wrote: >Defaults to nodsi in sched00 I'm guessing > I'm very naive here. All I know is from a search that found: https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.apss000/deppt.htm Other hits seem to indicate that NODSI stands for NO Data Set Integrity. I can't imagine why anyone would *ever* want to run any program in that condition. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN **CAUTION EXTERNAL EMAIL** **DO NOT open attachments or click on links from unknown senders or unexpected emails** This e-mail transmission contains information that is confidential and may be privileged.
