-- Migration 101: Reschedule mimecast-sync off the 0 2 * * * cron collision.
|
||
|
|
--
|
||
|
|
-- mimecast-sync was seeded at '0 2 * * *', the same slot as qbo-sync-2am and
|
||
|
|
-- veeam-full. Because the sync-scheduler dispatch table had no branches for
|
||
|
|
-- 'mimecast-sync' or 'qbo' (fixed alongside this migration), both jobs were
|
||
|
|
-- silently falling through to the generic Autotask fullSync() catch-all,
|
||
|
|
-- which meant they never ran their real sync logic AND contended with
|
||
|
|
-- veeam-full for the SyncService singleton mutex — producing
|
||
|
|
-- "A sync operation is already in progress" lock errors at 2 AM.
|
||
|
|
--
|
||
|
|
-- Moves mimecast-sync to 4:45 AM (minute 45 is unused anywhere in the live
|
||
|
|
-- sync_schedules table — avoids 0 4 (contract-services, pax8-daily), 30 4
|
||
|
|
-- (tickets-reconcile), the 15 * * * * hourly device-link job, and the
|
||
|
|
-- */30 :00/:30 veeam jobs).
|
||
|
|
--
|
||
|
|
-- Guarded on the stale cron value so this is a no-op if already moved (safe
|
||
|
|
-- to re-run) and won't clobber an admin's manual schedule change made via
|
||
|
|
-- /admin after this ships.
