Re: [U2] Array Types
I understand the performance trade off between dynamic and dimensioned arrays but I'm curious about quantifying. I know the answer will depend on hardware and load, but in general at what point (length) do dimensioned arrays become better performing than dynamic? 1000? 1? 10? Any examples or benchmarks appreciated. Jeff Butera Sent from my iPhone On Jul 27, 2012, at 11:14 AM, David L.

Re: [U2] UniVerse backups to disk
We don't mirror but we use filesystem snapshotting for a clean backup with less than 10 seconds of downtime: Dbpause Sleep few (3-5) seconds File system snapshot (5 seconds or so) Dbresume Backup from snapshot Trash snapshot Only cost in this is enough disk for snapshot.

Re: [U2] UniVerse backups to disk
Yes this is on Linux (we don't touch windows here). Same approach works on solaris and other *nix but I'm betting someone who knows windows better than I could also make it work.

Re: [U2] How to Clear Empty VM marks in Field

Re: [U2] Sequential Files Question
