I noticed almost all of my PC's idling. Caches are full with WU's processed, but no sending old / getting new WU's.
----------------------------------------I assume there is maintenance going on now(?). What about the idea of sending a signal through the Boinc client about a week in advance? So you can either enlarge the cache temporarily, or shutdown your PC, or however you want to anticipate on that. And ppl don't need to post questions about 'maintenance going on'?  As it is now (me running 24/7) most of my PC's are doing nothing. A waste of time and processing power. Just my 2 cts. [Edit 1 times, last edit by DE KOMETEN at Apr 22, 2020 3:36:57 PM] |

Maybe the notice was double dutch to you, but the printed text does say exactly that
Planned Maintenance on Wednesday, April 22, 2020 20 Apr 2020 Summary We are performing database maintenance on Wednesday, April 22, 2020 starting at 13:00 UTC. We are performing maintenance on the BOINC database in order to improve performance and capacity. This work will start on Wednesday, April 22, 2020 at 13:00 UTC, and will take about five hours. During the entire time of the maintenance, volunteers will not be able to obtain new work or report completed work. Volunteers will not be able check on the status of their results, but the rest of the website will remain available. Volunteers will not need to take any particular action, as your devices will automatically retry their connections after the maintenance work is completed. We appreciate your patience and participation. Loving it though, the validated work is already 3 times my computer's daily capacity, yet the pending validation is not moving an inch. 162 results so far, when normally around 40. Techs, something is wrong. |

Techs, something is wrong. The maintenance window isn't over nor is the work complete. However, since we reached a point in the maintenance work where we could turn the feeder on so that people could report completed work and get new work, we went ahead and did that. However, we will not be able to turn on the back-end daemons for another 90 minutes or so. Until that time, validation will not run. [Edit 2 times, last edit by knreed at Apr 22, 2020 3:53:19 PM] |

Not getting any new work but everything has been reported. Does the assignment of new work need the database?

Just asking as I don't get it that 162 results of mine all with a mod time of 13:59:52 suddenly seem to have ResultdId numbers that are 86nnnnnnn, e.g. 865660699, where before the same result on my archive has the ResultId 1557142675 for SCC1_0003843_FoxO1-A_10612_2, all of recent are in that 155nnnnnnn range. Note that the ResultId is the unique filter element for me, not the result name to determine, A is it on archive, B is it valid, C, is it current statistics period modtime.

The database and BOINC code use signed ints for result.id and workunit.id*. As of this morning, max(result.id) = 1,561,950,233 and max(workunit.id) = 1,554,294,365. The max value for a signed int is 2,147,483,647. At our current rate of 2,000,000 results per day, we would exhaust the id range in 292 days. Normally we wouldn't have taken action yet.
However, based on the experiences of Folding@Home and Rosetta@Home we wanted to be prepared for up to an 8x increase in participation and we wanted to make sure that anything that could disrupt the experience was taken care of before the launch of the OpenPandemics - COVID19 project As a result, today's maintenance work consists of increase the database RAM and storage by 3x. It also consists of shifting the ids for result and workunit back down to 1. Today's maintenance was the last bit of work we had to do in order to prepare our infrastructure to handle the increased capacity. Now we wait and see what actually happens. * I think the current BOINC code has changed to using unsigned ints which gives more headroom in terms of these ids. We would like to move to that code but other priorities continue to move in front of that effort. |

BUT, to emphasize you renumbered the tasks that had already returned and validated in previous periods. Now my program thinks there are 162 new results.
----------------------------------------Edit: BTW, nothing seems to have validated since the DB came back on line and now seems to be offline again 39684 World Community Grid 4/22/2020 10:42:32 PM Scheduler request failed: HTTP service unavailable 39685 World Community Grid 4/22/2020 10:42:32 PM [sched_op] Deferring communication for 01:46:50 39686 World Community Grid 4/22/2020 10:42:32 PM [sched_op] Reason: Scheduler request failed [Edit 1 times, last edit by Former Member at Apr 22, 2020 8:45:38 PM] |

When I got the notice ( well in advance ) I set my preference options to hold 1 more day of work to keep my system busy during the maintenance.
