Re: [U2] Quick question on Longnames
First, I think you would be hard pressed to find a modern system that does not support longnames. It is my understanding that the 14 character limit in Unix when out somewhere around System III (Any Unix historians in the house?). If anyone is aware of a current platform that still has this restriction, please let us know. Second, longnames=on has a couple of advantages: 1) It makes things much easier to work with at the Unix level, both scripting and manually; 2) It is slightly more efficient in that file opens can be done with one Unix open rather than multiple opens to get down the 'chucked' pathname. (Ignoring the VOC read, etc. to simplify the point.) To me, #1 is the most important. Thus I always turn longnames on and recommend my clients do the same. -- Regards, Clif ~~~ W.

Re: [U2] Quick question on Longnames
Just as a note, when universe went to IBM, and Ascential kept its own (now evolved) version, the first thing we did was change all the product files from Type1 to Type19 files; you won't find a Type1 installed on a DS Server unless it was manually created or existed prior to rev6 of the product. I know of no UNIX system in existence today that has these ancient restrictions.

Re: [U2] Quick question on Longnames
LONGNAMES ON is always to be recommended these days. There are so few UNIX variants now that require a file name to be limited to 14 characters. There are no negative implications (unless you'll miss the file created with a truncated operating system name messages!). LONGNAMES ON means that files can be created with names as long as the operating system permits. --- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/
RE: [U2] Quick question on Longnames
Absolutely, longnames on should be automatic (and check that on in the install automatically updates NEWACC) but imho longnames is far less of a problem than Type1 files which are an absolute pain. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Glenn Herbert Sent: 11 November 2004 19:26 To: [EMAIL PROTECTED] Subject: Re: [U2] Quick question on Longnames Just as a note, when universe went to IBM, and Ascential kept its own (now evolved) version, the first thing we did was change all the product files from Type1 to Type19 files; you won't find a Type1 installed on a DS Server unless it was manually created or existed prior to rev6 of the product.

So why isn't it the default on installation? Yes, I know it isn't your fault, Ray! LeRoy? Wally? Shouldn't the installer software set LONGNAMES ON unless the user specifically asks for it to be OFF?

Re: [U2] Quick question on Longnames
You know, some days the brain just doesn't work very well. Since I probably caused confusion to some of the newer folks with my previous blathering, let me point out that I answered the question of longnames by talking about the Type1 vs Type19 issue. Smooth, real smooth. Longnames handles the mapping of UV filenames with length 14 chars into a Unix file name of only 14 characters (those 000 and 001 files). The VOC file record ID will have the full name with the truncated and numbered file names used in fields 2 and 3 of the F pointer. Even with longnames on, type 1 files still break down into subdirectories. My preferred usage: LONGNAMES ON Type1 files == evil Type19 files == good Sorry 'bout the flub. -- Regards, Clif ~~~ W.

RE: Unclassified RE: [U2] Quick question on Longnames
Yeah, and get rid of Type1 for dirs in uvhome while you're at it (catdir, APP.PROGS, BP, INCLUDE, etc.). And default file types for SAVEDLISTS, PH, COMO, HOLD should be Type19 when they get created, too.
