When viewing my http://setiathome.berkeley.edu/hosts_user.php there are many computers that have been decommissioned and scrapped. How do I get rid of all but the active computers on my Seti Account. If they have not been crunching numbers for more than 90 days it stands to reason that either they have met an untimely death or have been decommissioned and used for other purposes like door stops or sold for scrap or had the Operating system updated and it can't be merged with the newer OS even though the computer has the same name etc. or the computers name was changed on my network an the seti page has the new computer name and the old name is there. I would like the ability to clean up that god awe-full clutter. its like keeping you utility bills for the last 5 places you lived at in the last 15 years in your bottom desk drawer. Totally useless unless you are a hoarder and want to collect things to start a fire with

If the tasks list of a computer is empty, there's a "Delete this computer" link at the bottom of its details page.

Hmmm NOT TRUE
when i click on details an delete this computer I get You can not delete our record of this computer because our database still contains work for it. You must wait a few days until the work for this computer has been deleted from the project database. if i click on merge i No hosts are eligible for merging with this one. when i click on task for the computer in question i get This feature is turned off temporarily.
when i check the server status page all are green and running except for ap_assimilator1 synergy Disabled
ntpckr_small_sig1 synergy Not Running
ntpckr_small_sig2 synergy Not Running
ntpckr_small_sig3 synergy Not Running
ntpckr_small_sig4 synergy Not Running
rfi1_small_sig synergy Disabled
rfi2_small_sig synergy Disabled
rfi3_small_sig synergy Disabled
rfi4_small_sig synergy Disabled
No wonder the project has so many problems everything reports that it is up and running but the data base is so corrupt you cant remove or merge computers from like 5 years ago.

The machine that is off had a memory fault that is being worked on. The memory has been replaced and the machine and all its data is being checked before the services are turned back on.

When anything is slow with the database, there are a few features that are not required for processing work that get turned off to save processing time on the DB server. This is not DB corruption.

Please remember that the project has a shoe string budget and only has a couple of employees.

Well is that machine that allow me to delete my 5 year old computers up or do I have to wait another year or two.
and that merge feature is still not working, The machine I want to delete was running 32bit vista and since has had the OS upgraded to windos7 64bit and has a new hard disk and more memory, but the server wont allow me the merge it with the new install or delete it because the corrupt data base says it still has work units to do even though I had turned off getting new work for the machine and completed all the work units and uploaded the results before wiping the drive and installing the disk and memory upgrade and the new OS. but the data base still says it has work to do. LOL

Does the machine you wish to delete still have work assigned to it (not just downloaded on the machine)? If so, that is the reason why you can't delete it yet.

I would imagine not, as I have stated i set bionc to not get any more work, I then allowed all the work to complete and used project update button to upload the completed unit results. I then installed more memory and a new drive and loaded win7 on it and added it to the cluster. that was some time ago.
I still can't merge the old results and computer ID into the new install and new ID or delete the record of it. the database keeps saying it has work to do

On that computer's page, are there any tasks listed?

Tasks are not removed from a computer until they are either discarded as having errored out on too many computers or the good result has been copied to the science database.

You imagine not... but did you check? When you go into that computer's page to merge, does it still show work as being assigned to the old computer ID on the web? If so, that's why you can't merge.

Yes I have checked before and there were none, for the longest time the web page says This feature is turned off temporarily.
Hmm probably one of the reasons for all the problems the project suffers from, is all the redundant obsolete data that the server keeps that clogs up the data base causing it to crash.
I fail to see the reasoning behind keeping records of all the computer and what work-units were assigned to them.
All that really matter is keeping a record of the work units that were processed and that the science is sound and the results can be duplicated and verified by other computers.

The project doesn't keep a permanent record of all the computers and all the workunits they've crunched. As soon as a workunit has met it's quorum, it's result is entered into the Master Science Database and the workunit is removed from the web.

That's the problem here with your computer is that there is likely (ghost) work still assigned to the computer you wish to delete, or the fact that the feature is disabled that is preventing you from removing the computer at this time.

Have patience, and once the feature is back on you can verify if there's still work assigned, and if not you can simply remove it then.

[Edit] In fact, I just read that they turned the feature back on, so you can try now.
