Question, does the logic error produce any kind of message so that you can be warned of the potential problem?
-----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Jousma, David Sent: Monday, October 02, 2017 8:03 AM To: [email protected] Subject: Re: APAR OA53994 All, just an FYI, we are in the middle of a maintenance cycle, and happened to pick up these offending PTF's awhile back. IBM does have an APARFIX available. I'm working with them trying to gauge the confidence level in it. They have updated the text of the APAR to include the conditions required for it to occur. Probably a fairly rare case, but good to close the hole. ERROR DESCRIPTION: During CLOSE processing of an extended format dataset, a logic error occurs causing the blocks at the end of the dataset to not be written out to the dataset if the I/O has not completed yet. Conditions for problem to occur: - QSAM and OUTPUT - Physical Sequential Extended Format dataset - During close processing, the dataset must run out of space in the current extent. This will drive EOV processing to get a new extent and re-drive i/o. - The i/o must not complete before we get to the invalid code path. If it completes, there is no problem. _________________________________________________________________ Dave Jousma Manager Mainframe Engineering, Assistant Vice President [email protected] 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 -----Original Message----- From: Jousma, David Sent: Monday, October 02, 2017 7:51 AM To: 'IBM Mainframe Discussion List' Subject: RE: APAR OA53994 Thanks for the heads up Skip. _________________________________________________________________ Dave Jousma Manager Mainframe Engineering, Assistant Vice President [email protected] 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Jesse 1 Robinson Sent: Friday, September 29, 2017 3:11 PM To: [email protected] Subject: APAR OA53994 **CAUTION EXTERNAL EMAIL** **DO NOT open attachments or click on links from unknown senders or unexpected emails** I just got a notice from ASAP that APAR OA53994 has PEed PTF UA91904 , which we installed in July. It looks pretty serious: records dropped at the end of an extended format sequential file. We have had no reports of such a problem, but it's pretty worrying. Has anyone stumbled on this crack in the sidewalk? . .
