This includes > open source software like Apache, Samba (CIFS), GNV, etc. For these systems, the VMS C RTL will be fine with calls like locatime(), since this returns the VMS clock, but not with calls like gmtime() which convert to GMT. (The opposite of the convention used by UNIX). Of course, this assumes you do something to keep the VMS time correct (like a patched Multinet runing NTP). As a result this is very much application dependent, and can't be a problem for VMS 5.x where gmtime() returned NULL, as allowed by ANSI. (IIRC 5.5-2 is still under prior version support for those of us who had to "land" some of our systems there.) ------------------------------ Date: Fri, 9 Feb 2007 08:58:17 +0000 (UTC) From: helbig@astro.multiCLOTHESvax.de (Phillip Helbig---remove CLOTHES to reply) Subject: Re: Help configuring VMS mail with Dynaccess.com Message-ID: In article <45CB355D.2070009@comcast.net>, "Richard B. gilbert" writes: > The typical NAT router configures itself via DHCP and, as part of the > process, is given the addresses of two or three DNS servers.

All of them are DHCP clients with respect to the WAN, and can be DHCP servers with respect to the LAN (I don't use DHCP on my VMS machines, though). ALL of them pick up DNS servers when they are configured via DHCP. However, only SOME of them will in turn act as a nameserver for machines on the LAN. Thus, the ones that don't must be getting the DNS servers for some other reason. ------------------------------ Date: 9 Feb 2007 05:30:07 -0800 From: "klaus_austria" Subject: Re: Migrating C application from VMS to LINUX Message-ID: <1171027806.256364.215590@l53g2000cwa.googlegroups.com> On Feb 9, 1:07 pm, Kilgal...@SpamCop.net (Larry Kilgallen) wrote: > In article <1171017147.288767.101...@a34g2000cwb.googlegroups.com>, "klaus_austria" writes: > > > I plan to migrate from VMS to Linux.

Is there a chance > in Unix too? > What else could cause problems? Sigh. Another one lost. "global logs" are not a built in part of VMS, please explain further. If you mean logical names, you might be able to emulate those via file system links, shell symbols, or via a shared file containing the data, this is quite application dependent. global sections are like C shmem calls. There are third party tools that will emulate parts of VMS under UNIX if you have lots of VMS specific code. I'm quite sure there are UNIX systems which support SNA, but you'll have to check with the Linux community to see if SNA support exists. (I would not be suprised if IBM already made this available.) ------------------------------ Date: 8 Feb 2007 23:21:00 -0800 From: "Volker Halle" Subject: Re: Quorum disk removal Message-ID: <1171005660.569380.151130@v45g2000cwv.googlegroups.com> John, I know one thing for sure from prior experience: If you had a quorum disk in a cluster and have set DISK_QUORUM="" in the various cluster members over time and rebooted each of them, the 'knowledge' about the 'previous' quorum disk name still exists in the dynamic cluster data structures in memory. SHOW CLUSTER/CONT and ADD QD_NAME still shows that old quorum disk name, even if it has been removed from all individual systems. It does show QF_VOTE: NO As it is not allowed/supported to have 2 different quorum disks in a cluster, bringing in a new quorum disk may cause problems, but it may also work. A cluster reboot would be the only supported way to change the quorum disk - but you probably know this and just want to try to prevent a cluster reboot...

I was somewhat expecting that each non-QW would maintain the disk quorum somewhere - and my goal of avoiding a cluster reboot may be in vain. I would not have 2 different disks - at least from the respect of the DISK_QUORUM - however back to what is in memory. That said, I have booted a server with the DISK_QUORUM set (same as the other servers) - however the quorum disk was not mounted. The resulting OPCOM message had something like "remote access" and "please mount quorum disk". And if I remember correctly, it did boot - just the OPCOM messages every so oftern. Which leads me to believe that I can do this - just that OPCOM will complain during the transition.

The "please mount quorum disk" messages are harmess - the quorum disk system still works correctly without doing so, but the normal file system locking etc. aren't present to protect the filestructure. ------------------------------ Date: 9 Feb 2007 07:43:55 -0800 From: "Volker Halle" Subject: Re: Quorum disk removal Message-ID: <1171035834.393359.180820@a34g2000cwb.googlegroups.com> John, the 'please mount quorum disk' message is quite important, if this is a NEW quorum disk and the QUORUM.DAT file has not yet been created. In that case, the quorum disk votes do NOT count towards quorum, unless you mount the disk, which allows OpenVMS to create the quorum file. If there already is a QUORUM.DAT file on that disk, OpenVMS will recoggnize the quroum disk and count the votes, even if the disk has not yet been mounted.

What happens if this storage device fails? I'm quite familiar with how PKZIP does this, and somewhat familiar with how Legato does this (mostly from dealing with failures). ------------------------------ End of INFO-VAX 2007.080 ************************
