Happy birthday, cluster!

On 13 april 1997, at 11:35:50 MET DST (09:35:50 GMT) our cluster came into existence,
It has been providing continuous service to our users ever since.

So, today we celebrate
9 YEAR UPTIME.

Proost.

Have one on me (maybe in May in Nashua?)

Re: Happy birthday, cluster!

9 year uptime... unbelievable. We replace clusters about every 4 years. Well done.

Re: Happy birthday, cluster!

Congrats Jan.

I have a 2000 that is power off since 3 years but still not gone due to a difficult organization. Happy birthday too.

Re: Happy birthday, cluster!

Congratulations on your new birthday. Not the longest uptime but very impressive considering the hardware changes and relocations.

With the right cluster configuration, it's entirely possible that Jan has replaced all the hardware, and possibly even moved buildings in those 9 years, while still maintaining the cluster foundation date. All it needs is for at least one node to remain running at all times.

Application up time does not depend on a single node remaining up all the time, it just needs at least one member of the cluster to be up.

Re: Happy birthday, cluster!

Congrats Jan,

I'm counting down another 6 weeks to be able to report 3 yrs. uptime on a VAX4000-100 (which regrettably will have its final power down in 3 months time - to be replaced by the W...-stuff).
Can't wait to announce the 3 yrs. uptime to all my other collegues (I'm the only VMS guy left; outnumbered 10 to 1)

Re: Happy birthday, cluster!

Congrats on the long uptime.

Real clustering is a wonderful thing.

Re: Happy birthday, cluster!

The key point is not the cluster up time but that Jan and colleages have maintained continuous application availability for 9 years.

This is a very impressive system management archivement.

IIRC the cluster has been relocated and all the hardware replaced.

Re: Happy birthday, cluster!

Jan,

Congratulations from NYC!

All too few people remember that it is meeting the availability requirements on a continuous basis that counts, not how much emergency work has to be done.

Nine years to continuous availability of an integrated system, across version changes, technology changes, and location changes is an achievement that no other OS can meet.

Re: Happy birthday, cluster!

Are you sure it wasn't a windows system up all these years?

I mean, VMS must be one of those antiquated legacy systems, with tubes that heat up, addresses we walk to, switches to set, and wires?

More similar to a weaving machine than some kind of modern contraption?

Re: Happy birthday, cluster!

Jan,

Nine years is a great feat! Of course we all have come to expect this kind of performance from OpenVMS.

Should we start planning for the cluster's 10th birthday yet? That event will be a true milestone!

Re: Happy birthday, cluster!

Thomas,

like John said, there can, and have been, "some" changes... the oldest piece of hardware (including screws, wires, anything you can hold, or drop) dates from 2000 or later. EVERYTHING has been replaced at least once.
It is all about continuously providing desired services that counts (at least for us), and the results for THAT vary somewhat per application, but the better designed ( = designed on & for VMS ) applications have (nearly) perfect scores, with one at only some 10 minutes less than the cluster itself.

For those that do not yet know our cluster (or like to revisit :-)

Some recent devellopment: although it still RUNS most backoffice apps for the Regio Politie Amsterdam-Amstelland, it has now been outsources to a newly-created, countrywide Service Organisation.
They are consolidating several regio's into above-regional service areas, and it is by no means certain that (or for how long) this cluster can continue.
But, we have been saying that also for several years now. We will just have to wait and see...

Re: Happy birthday, cluster!

Not sure how many more times the word unbelievable can be mentioned in this thread, but - UNBELIEVABLE!

Truly outstanding ... well done! I'm sure you folks have quite a talented team out there.

The best I have is a terminal server in Toronto:

DS700-08 BL47-60 ROM V6.3-0 Uptime: 991 21:42:23

Even though this is completely dwarfed by your accomplishments, it is somewhat special ... it somehow survived the massive power failure/rolling blackouts eastern Canada/US suffered a couple of years ago.

Cheers,
