Speaking of tuning, I have a question about Linux kernel parameters. Back a while ago we started having intermittent problems running a DB backup on one of our V6 systems. From what I posted here, a responder with the same problem came upon some documentation listing recommended kernel parms for Linux servers and DB2.
So my OS guy went around to all of our TSM servers and set the nofiles value to 4096, along with other recommended tuning parms. Now we are see this message on most of our servers: ANR3619W The user limit for open files is below the recommended minimum value of 4096. eventhough IT IS set to 4096 What is especially annoying is seeing this on my offsite TSM server that does nothing but hold DBSNAPSHOT backups performed once a day by my 7-production servers. No real backup processing - no client activity. Suggestions? On Wed, Apr 17, 2013 at 1:36 AM, Köhler, Marcus <marcus.koeh...@rossmann.de>wrote: > Hello Andy, > > thanks for sharing that with us.
