For most regions the standard LL rolling restarts happen on Tuesday mornings (SLT), and on Wednesday for the remaining regions. Certain configurations of the E2V system can be affected by these restarts, and this article explains those situations.
Please see this article to be sure which version of the system you have, as it makes a big difference when it comes to rolling restarts!
To understand the impact rolling restarts can have on the E2V system in your store, it’s important to first understand how your store is (or can be) configured when it comes to product delivery. The list of rules is:
- If your vendor is using 2.9 or earlier, product is always delivered from the Inventor Server as a box.
- If your vendor is using 2.13 or later, you have the option of product being delivered as a box from the vendor itself, or as a box from the Inventory Server.
- If your vendor is using any version 3 script, you have the 3 options. Product is either delivered from the vendor prim as a box, from the vendor prim as a folder, or from the Inventory Server as a box.
(“Box” in this context means a single object, which might be a box, or a bag, or a duck, or whatever.)
If your store is configured to deliver product from the Inventory Server, and your Inventory Server is not on the same region as your store, then it’s possible for product delivery to be affected by a rolling restart, as the Inventory Server basically ceases to exist while that region is being restarted.
With version 2, there’s only one way to avoid delivery problems during the time the Inventory Server’s region is being restarted, and that is to Take A Copy of the server, and rez it on the store region.
For version 3 users, you have more choices.
First, you can do nothing. This is because the Delivery Relay will queue up purchases while the server is unavailable, and will then process them once the server (i.e. region) comes back online.
Second, you also put a copy of the server on the store region.
Third, you can use a backup Inventory Server. The backup server would only be used during the time that the primary Inventory Server is unreachable. Soon after the primary server region comes back online, the Delivery Relay will automatically switch back to the primary server.
