IIS Recycling Best Practices

[EPETERS (Eric Peters)]

Good Morning,

Over the past couple of weeks, I’ve had to recycle IIS on our production db due to log in errors first thing in the AM. It seems as if the daily recycle I have set for 3:30AM is not always starting the pool back up properly. We are a 20 hour x 7 days a week shop, so having IIS recycle at its normal 29 hour period is an issue because while it is recycling, there are a number or process errors. My intention was to set the recycle for a time when no one is processing. Do anyone else run into this issue? Is there something I can set up to avoid these app pool failures?

Thanks in advance,
Eric

lots of very good info like:

IISRESET: the (almost never) good, the bad and the ugly

[image] Adam Rash http://iotacons.blogspot.com/ Now that Epicor ERP is using a pure Microsoft stack there are some habits that are in heavy use that once were considered OK but now are no longer considered best practices. As with any new technology, those of us learning it as we go along are beholden to the experts to help us avoid pitfalls. This post is to discuss one of those behaviors with IIS that is so ingrained into our collective IIS admin psyche that even those that know about it fal…

Thanks. I just read that, but it really speaks about ways to avoid using IISRESET. I never use that and I’m only having an issue with one app pool, but it’s the production environment so I’m trying to avoid downtime.

Here’s another thread that involves confusion over when and how to cycle the app pool

Regenerate Data Model while DB is in use

Is there any danger to regenerating the data model (because UD fields were added), while people are using the system? And what about letting users use it in between regenerating the data model and restarting IIS?

This is good information. I guess recycling IIS is not an issue since it has to do it anyway. I changed it to recycle in the evening rather than overnight, so if there are any issues, I don’t keep waking up to the system being down first thing in the morning. If something goes wrong, at least I can address it during our slower 2nd shift. Thanks for all the info Calvin!
