[u2u] New Listserver
Hi all, The lists hosted by U2UG have been moved to a new server, and upgraded from majordomo to mailman. There will be a few changes in the administrative side of things (subscription management, etc), but the email address for the lists will remain the same. One not insignificant (but not really major) change is that mailman handles digests differently from majordomo. With majordomo there were 2 separate lists for each list -- a regular list and a digest list. Some folks were subscribed to BOTH the regular and digest lists. With mailman, this is no longer possible, since mailman only keeps a single list, and manages the digest based on user-selectable options. So anyone who was subscribed to a digest list and the corresponding regular list is now only subscribed to a single list, with the digest option turned on. Any user can now login and change their options from regular to digest for any of the lists to which they're subscribed. One other change is that administrative requests (subscribe, unsubscribe, etc) that are sent via email will no longer be sent to "majord...@listserver.u2ug.org", but to "listname-...@listserver.u2ug.org" where "listname" is one of the lists (i.e. u2-users, u2-community, etc), and "xxx" is one of several commands, such as join, leave, subscribe, unsubscribe, request, etc. For example, to subscribe to u2-users, send an email to "u2-users-j...@listserver.u2ug.org" (or "u2-users-subscr...@listserver.u2ug.org"). There will still be a web-based interface to the lists as well, but the url for that will change slightly as well. The new location will be http://listserver.u2ug.org/mailman/listinfo for general information, and a list of all of the mailing lists, or http://listserver.u2ug.org/mailman/listinfo/listname for list specific information and subscription management. http://listserver.u2ug.org redirects to the general listinfo page. The IP address was just changed to point to the new server last night, so it may be a day or so before the DNS servers around the globe are all fully updated. Please be patient as we work through these changes. We will work to correct any issues that arise as quickly as possible.

[U2] unidata hangs
Why why why do all unidata processes hang when a mount point dies - even if the mountpoint is not being used by any udt process ??? This drives me potty - it has happened again today where a mount for some data sharing went down because the other machine had a network problem. This mount was not used by any udt process just used at linux to copy some files etc. Every udt process, telnet sessions, phantoms, uniobjects processes then hangs. I have had to unmount the offending mount and stop and start unidata killing off all sorts of things ! Is there a way to stop this happening ? a different type of mount, a udt param, a udt upgrade (we are on 7.1) Cheers Symeon. ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
[U2] Blogs on GUI development
I've recently written two blogs which go into some detail about the options available to developers who want to put a GUI on their MV app. These are more oriented toward people who don't really understand the various mainstream buzzwords or how some of the more popular options compare to one another. The emphasis is on the idea that no matter what you choose, you will have a learning curve, but it helps to understand that your education won't be completely wasted should you learn about one option and then move to another. There are consistent paradigms in use, and sometimes just understanding that is helpful in making comparisons and choices. If you are familiar with the options, including those that make use of JavaScript and Ajax, or the various plugin tools like Flex and Silverlight, then your feedback is most welcome, but please remember the intended audience when going into detail. The best place to start is probably the main page: remove.this.spam.filterNebula-RnD.com/blog/ Look down the page for articles: "Still on a fence about GUI?" then "Web GUI tools - Not as different as they seem" There is also a more detailed article titled "Adobe Flex for MV GUI" if you wish to know more about that option. As stated in my recent entry "About this blog, taking a brief step back", I'm happy to accept comments and criticisms, so please let me know what else you'd like to see written up. Yes, I sell tools for which I have a bias, but for those of you concerned about ads I hope you will find my blogs are almost entirely non biased when I'm explaining options. I leave it to the reader to come to their own conclusions, and if their conclusions agree with mine then I will be ready to offer products and services to help with implementation. If not then I'm at least glad to have helped someone with their decision process. Finally, my blog home page has sidebar links to other MV-related blogs (and a couple that are not). I welcome you to visit these repositories of (arguable?) insight and to let me know if there are other MV blogs that should be added to the list. Blogs are homes to indepth notes that usually don't belong in forum discussions, and you often won't find the information or (arguably?) helpful perspectives anywhere else. As an example, my recent blog notes on web development relate closely to Brian Leaches recent blog on mvScript - you simply won't find this information anywhere else.

Re: [U2] unidata hangs
From the 7.1.15 readme: Issue 9809 - Problem Description UniData -- UniData maintains a table in shared memory that records information about your system's file systems and the available space in each file system. This table is used to quickly determine if a dynamic file has room to expand in its current directory or if a new part file needs to be created in another file system. The table is loaded when the database starts and is refreshed regularly by the smm daemon. Prior to this release, the smm daemon created entries in this table by forking the UNIX 'df' command. As smm relied on the specific format produced by the standard OS-provided df command, if an administrator replaced the standard 'df' command with a different df utility, smm was unable to properly parse the df output and create proper entries in the shared memory table. This could result in the inability to create or expand UniData dynamic files. This table can be viewed with the '$UDTBIN/sms -F' command. Here is an example of the normal, expected output: # $UDTBIN/sms -F File system table size (N_FILESYS):200, Used: 13 Device ID Available Space NFS File System Name (in 512 Bytes) 1073741827 621296 no / 1073741825 755264 no /stand 1073741833 1209600 no /var 1073741834 1736512 no /usr 1073807361 91514582 no /tshp1123 1073741832 1002224 no /tmp 1073741831 1027440 no /opt 1073741830 1320720 no /home 1073741829 9326052 no /disk2 1073741828 2599142 no /disk1 Starting with this release, smm no longer forks df to create the entries in this table. Instead, smm reads the platform-appropriate mount table to create the file system entries in this table. As smm does not fork a df command, any problem with the output format of a non-standard df command is avoided. In order to provide compatibility with prior releases, a new parameter is created in udtconfig: USE_DF. The default setting for this parameter is: USE_DF=0. This means 'use the new method of loading the shared memory table by reading the mount table'. If an administrator prefers to have smm continue to fork df (as in prior releases), they can set udtconfig USE_DF=1. UniData daemons must be stopped and restarted to implement any change to the USE_DF setting. NOTE: There have been a number of other problems associated with smm forking df, including: smm core dumping; defunct df processes spawned by smm. Most of these problems were triggered by the behavior of 'df' when nfs-mounted files systems became unavailable to the system. As smm no longer forks df, these problems should no longer occur at this release. ADDITIONAL NOTE: Customers have sometimes experienced a problem with a udt process hanging during initialization when an nfs mounted partition was unavailable (network or system down). This behavior may not be completely resolved by the fix for this issue. This hang was due to smm not responding to the login request from the udt process - typically because it was hung itself, waiting for a df process to complete. Even though we now avoid forking df, smm still re-calculates the space available in each file system every 60 seconds (by default). smm uses a standard UNIX statfs() system call to determine the space available on a file system. If smm is checking an nfs file system that is unavailable, that system call may still hang. The behavior of this varies by UNIX flavor. If you mount nfs file systems as a HARD mount, this system call may hang until that remote system becomes available again. smm will wait on that system call as well. IBM recommends that you consider using SOFT nfs mounts. There is typically a configurable number of retries that will be attempted before the system call returns with a failure status. This allows smm to continue after a brief pause, waiting for statfs() to return. Please consult your UNIX support provider for specific information about NFS SOFT mounts for your platform.

Re: [U2] [u2u] UV on Windows question
Others could probably reply better than I can, my experience is many years old, but the biggest difference that I remember was the UV/Win did not have the spooler that UV/Unix had.

Re: [U2] [u2u] UV on Windows question
The most significant difference between UV/nix and UV/doz in our experience is that UV/doz does not have any print spooler whatsoever. Each print job goes directly to the Windows spooler and then to the associated Windows printer. Our SpoolerPlus software product provides both a print spooler for Universe and the functions and commands necessary to emulate the generic Pick print spooler on UV/doz, UV/nix, UD/doz, UD/nix, QM/doz and QM/nix. SpoolerPlus solves the problem of the missing spooler on UV/doz and provides a much richer print spooler architecture than that provided by the native UV, UD and QM databases (IMHO) That said, my sense is that it is much easier to create printers in UV/doz than it is in UV/nix.
