[quote="stevie"]Cupid, I don't accept your reply. If the servers can coordinate with each other to schedule bids (i.e. one says to the other, "you need to bid on this"), they can coordinate to cancel scheduled bids (i.e. one says to the other, "you don't need to bid on this one any more"). It wouldn't make it less reliable. You don't want to do it - that I get. I'll be more cautious about using Gixen grouping in future, and if I find a service that does offer grouping and resilience, maybe I'll give that a go for a while and see how I get on.[/quote]

I don't develop it at all... Mario does, I am just a user like yourself, albeit one with some experience of development and support of similar IT projects. <br /> <br />The fact is though that scheduling snipes on two servers is a very different process from automated cancellation between two servers each of which is independently tasked with placing bids. Especially when you consider that snipes may already be in flight when they require cancellation... it isn't as simple as a deletion from a database... like just being the opposite of adding one (which, if it happens to be too late, just doesn't get executed, as already highlighted extensively on the site)... The cancellation requests would have to flow both ways and confirmations then sent and received both ways also. Any wait for response between the two servers couples them... and if one goes down that affects the other... there IS less reliability in that scenario. <br /> <br />The whole point of having two servers working for you is that if one has issues the other works for you.. if you make one stop, or even just run less efficiently/slower, when the other has a problem then you pretty much defeat the point of having them both. <br /> <br />I postulated a solution many years ago... when I pointed out that the method Gixen uses to detect the success (in winning) or failure of a snipe by seeing, once the auction is closed, if the actual price is higher than the bid submitted is not the way that I detect whether or not I won an auction... that would be looking in my 'Purchase history' on Ebay... and that could be done independent of the placement of the bid.. then that could be used to decouple the process of cancellation between two servers... but it would slow things down considerably and mean that auctions within a few minutes of each other could never be dependably placed in the same Group without there being a higher risk of both being won... I believe that was considered worse than the current implementation of keeping all Group snipes on the Main server only.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="templates/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> <tr> <td width="22%" align="left" valign="top" class="row2"><span class="name"><a name=""></a><b>stevie</b></span></td> <td class="row2" height="28" valign="top"><table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td width="100%"><img src="templates/subSilver/images/icon_minipost.gif" width="12" height="9" alt="Post" title="Post" border="0" /><span class="postdetails">Posted: Thu Jul 09, 2015 12:20 am<span class="gen"> </span> Post subject: 'HTTP TIMEOUT (77)' and no mirror entry</span></td> </tr> <tr> <td colspan="2"><hr /></td> </tr> <tr> <td colspan="2"><span class="postbody">Cupid, I don't accept your reply.

I did not mean to imply that Mirroring of Grouped snipes would not be an advantage... just that it is not as essential as for non Grouped snipes (that is what I mean by 'gain less' i.e. you don't gain as much), since you have other chances to win the thing you want. <br /> <br />I was also trying to say that with two servers, bidding independently, it would be technically a great deal more difficult to have later snipes cancelled when you do win an auction... since both servers would then need to cancel those snipes and the win may happen via a bid from either... This is the reason Mario decided to specifically exclude Grouped snipes from the Mirror implementation. <br /> <br />It is a feature of the implementation that the servers act independently of each other when placing bids... any interaction between them at that stage would decrease the overall reliability due to the greater coupling of processes.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="templates/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> <tr> <td width="22%" align="left" valign="top" class="row2"><span class="name"><a name=""></a><b>stevie</b></span></td> <td class="row2" height="28" valign="top"><table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td width="100%"><img src="templates/subSilver/images/icon_minipost.gif" width="12" height="9" alt="Post" title="Post" border="0" /><span class="postdetails">Posted: Tue Jun 30, 2015 8:34 am<span class="gen"> </span> Post subject: 'HTTP TIMEOUT (77)' and no mirror entry</span></td> </tr> <tr> <td colspan="2"><hr /></td> </tr> <tr> <td colspan="2"><span class="postbody">Sorry to say, but this makes no sense to me: <br /> <br />> Group snipes, by definition, are replaceable by each other... <br />> so you would gain less by having such snipes Mirrored, <br /> <br />I imagine I am bidding for a couple of splungecrockets, one of which comes up today and the other comes up tomorrow. I only want one splungecrocket, so I put them in a group, so that if the first one wins the second one is cancelled, but if the first one is outbid then gixen goes on to bid on the next one for me tomorrow. <br /> <br />Now, at this point, if they are not mirrored, it means that I am one HTTP TIMEOUT away from my bid failing -as happened to me earlier in the week. But if they are mirrored, it means that even if one server encounters a HTTP timeout error, there is a very good chance that the other server's bid will complete anyway and so I still get to bid. <br /> <br />So with mirroring, I gain, because my snipe is more likely to happen. And I see nothing that is worse (not a gain) by having mirroring. If it's mirrored, my chances of the snipe happening are much higher than if it's not mirrored. What's not to like? I cannot see how it is that I would gain less (than what?) by having my grouped snipes mirrored. <br /> <br />Perhaps I missed something - please do let me know if so, preferably with examples. <br /> <br />Thanks.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="templates/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> <tr> <td width="22%" align="left" valign="top" class="row1"><span class="name"><a name=""></a><b>Cupid</b></span></td> <td class="row1" height="28" valign="top"><table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td width="100%"><img src="templates/subSilver/images/icon_minipost.gif" width="12" height="9" alt="Post" title="Post" border="0" /><span class="postdetails">Posted: Mon Jun 29, 2015 1:39 am<span class="gen"> </span> Post subject: </span></td> </tr> <tr> <td colspan="2"><hr /></td> </tr> <tr> <td colspan="2"><span class="postbody">Group snipes, by definition, are replaceable by each other... so you would gain less by having such snipes Mirrored, even if the interconnection between them were technical possible to implement on two servers. <br /> <br />There are other advantages of a Mirror subscription, like variable offsets, multi-win groups etc. that you can still take advantage of, even if you only ever set up Grouped snipes.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="templates/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> <tr> <td width="22%" align="left" valign="top" class="row2"><span class="name"><a name=""></a><b>stevie</b></span></td> <td class="row2" height="28" valign="top"><table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td width="100%"><img src="templates/subSilver/images/icon_minipost.gif" width="12" height="9" alt="Post" title="Post" border="0" /><span class="postdetails">Posted: Mon Jun 29, 2015 12:08 am<span class="gen"> </span> Post subject: 'HTTP TIMEOUT (77)' and no mirror entry</span></td> </tr> <tr> <td colspan="2"><hr /></td> </tr> <tr> <td colspan="2"><span class="postbody">> Was this snipe part of a Group? <br /> <br />Yes. <br /> <br />> That would explain it, since snipes in Groups are never Mirrored. <br /> <br />Thanks for the explanation - useful.
