Hi Wally, I just confirmed with our Admin that it was programs crashing, not a corrupt file that required the reboot.
Thanks for the clarification and actual issue ID. -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Wally Terhune Sent: Wednesday, 4 May 2011 10:02 AM To: U2 Users List Subject: Re: [U2] Unidata RESIZE CONCURRENT I am not aware of any problems with RESIZE CONCURRENT that resulted in a corrupt file. There is a problem that can occur that results in a WRITE failure, but not physical file corruption. From the 7.2.8 readme (for Linux you will need to upgrade to 7.2.9): Issue UDT-3787 - Problem Description UniBasic -- After a RESIZE CONCURRENT command had been run on any UniData file on a server, subsequent updates to records in another UniData file could result in a fatal UniBasic runtime error: U_LLM_Release error 7 This problem occurred very rarely. While it could occur with an update to any UniData file type, it had only been reported with updates to a DIR-type file within UniBasic.

We tried this on 7.2.5 in Dev and required a reboot from corruption. We were informed we need to upgrade 7.2.8 to get the fix for it. As always, I'd suggest doing anything new a few times on a Dev server before trying it on a Production server.

Historically, we have had downtime and a brief (1 hour) maintenance window each week where we memresize our files. We'd like to switchover to RESIZE/CONCURRENT to reduce downtime and would like to hear from anyone doing this on a production system. It's not that I don't trust it: I'm just looking for insight, gotchas, pros/cons of memresize vs RESIZE or other input from those who might've gone down this road already.
