RE: [U2] [UV] Named commons
Ah, that's a good idea...but I guess by-passing this restriction (which must be in place for a good reason), should not be taken lightly (especially in an mission critical environment). I guess you could also write some UV BASIC code based on RFC4122 if you want to be fully compliant. See the C source code supplied in http://www.ietf.org/rfc/rfc4122.txt.

Re: [U2] [UV] Named commons
Jacques, How unique do your UUID's need to be? Do you need them to conform to the 32 hex digit format? If not, you could generate unique identifiers based on the port number (@userno) and current date/time. Alternatively, you could use GCI to integrate the uuidgen function into the Universe shell. rex Jacques G. wrote: I need to generate UUID's Universe doesn't have a function that does this... --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
Re: [U2] [UV] Named commons
These are 2 other possibilities we are looking at. The GCI has the drawback that it requires C code and we may encounter a customer that doesn't have the C compiler on their server. We may end up doing something like this: UUID = DTX(CHECKSUM(@LOGNAME)):-:DTX(ABS(@USERNO)):-:DTX(CHECKSUM(SYSTEM (1302))):-:DTX(DATE()):-:DTX(INT(1*TIME())):-:DTX(RND(1000)) Someone at IBM suggested having Universe call an external Webservice to generate a UUID but that would be even slower than having a shell call the uuidgen program. - Original Message From: Rex Gozar [EMAIL PROTECTED] To: u2-users@listserver.u2ug.org Sent: Tuesday, February 12, 2008 1:22:57 PM Subject: Re: [U2] [UV] Named commons Jacques, How unique do your UUID's need to be?

Re: [U2] [UV] Named commons
DIGEST creates an MD5 checksum, but it's binary and you need to convert it to hex. See http://www-306.ibm.com/software/data/u2/pubs/library/ to get the latest documentation. rex --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
Re: [U2] [UV] Named commons
Hi, thanks for the example. What does DIGEST do ? I did HELP BASIC DIGEST at the TCL and it isn't in the online docs. Is it a Hash or encryption function that returns a 128 bit number ? - Original Message From: Rex Gozar [EMAIL PROTECTED] To: u2-users@listserver.u2ug.org Sent: Tuesday, February 12, 2008 1:48:40 PM Subject: Re: [U2] [UV] Named commons Jacques, Here's an example of generating a uuid using the userno and time.

Re: [U2] [UV] Named commons
A named common is visible from a session. If Bob is logged in on session 1 and Jane on session 2, Jane has no visibility to Bob's named common or vice versa. Certainly when someone logs in you could put your GUID in a named common and it'll be there until that person logs off. You'll still have to have some way of generating the GUID and that could lead to a record lock (unless you calculate a hash based on date/time/port/@logname, that sort of thing). -K2 --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

Also, if Bob is logged in on session 1 and Bob is also logged in again on session 2 , Bob2 has no visibility to Bob1's named common and vice versa. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kevin King Sent: February 12, 2008 11:39 AM To: u2-users@listserver.u2ug.org Subject: Re: [U2] [UV] Named commons A named common is visible from a session.
