Automatically clear cache?

Hey guys, I'm calling on a bit of your computer expertise here.

Is there a way to automate the clear cache process? Or have the cache clear out on a restart or something?

So far when updates go through, it's been getting difficult to remote into all my clients, clear their cache out one by one, then restart their display. I feel like there's an easier way to do this?

any ideas? Thanks!

    happy I’m optimistic about this becoming a future feature!

    Alex, I posed a similar question recently as I recently had to do the same thing to a number of displays. I believe that Robb suggested posting an idea / suggestion here, but I failed to remember to do so.

    I thought that it would be nice to have a "Clear Cache on Restarts" check box in the platform, at the Display level, and maybe have it checked by default when adding a new display.

    Do you want to formally share the idea here (or do you want me to)? I think its well worth pursuing....lets see if we can get it voted up.

    Hey guys,

    When you click "Restart Display" in the Display settings and choose to restart at a specified time, this will clear the cache.

    Jeff, I thought from your suggestion before, what you wanted was an option to "clear cache now" or something to that effect, where it would clear the cache immediately on the Display.

    Is there a reason why the cache being cleared at restart won't work for you?

    Thanks!

    Hey Robb, with that recent white screen issue, how come I needed to clear the cache on all my display manually? They are all set to restart every night.

    silly I’m eternally grateful (as usual)

    Robb, I didn't realize that particular option in the display setting would actually clear the cache, so I'm pretty excited to hear that! ;)

    Will restarting the entire windows machine (via any method) actually clear the cache as well? I ask because through the LogMeIn Central console, I have a task setup to restart all of my displays at a specific time each night. Although this is setup as a scheduled daily task, with a single mouse click, I can manually initiate this task at any time across my entire network.

    Thanks again!

    Alex,

    You may want to check this discussion to see if your Presentations meet the same criteria. We discovered a bug where if the Placeholder was empty that it won;t show up, so adding an empty text item will correct the issue for the time being. I figured since I hadn't heard from you that the restart on the day we deployed had fixed the issue. Sorry about that!

    Jeff, a regular restart won't clear the cache, it needs to be done through the system, since there are certain calls the Player makes when it is restarting the machine that clear the cache.

    Check out this blog post for the folders to clear if you want your restart task to clear them out every night.

    Thanks!

    Ok, got it - thanks! Sounds like if I wanted to do a nightly cache-clearing (which I really don't see the need for typically) ~and~ a windows restart, I could set the LMI network-wide task to run at say, 2:30am, then the Rise Display player restart option to run at 3:00am.

    And, now that I think back Robb, I believe you are correct: the scenario that started our discussion was related to doing an immediate, network-wide cache clearing to clear up some issues. An idea that still might be worth suggestion, so I may do that.

    Thanks again!

    Hey Jeff, I think you may be eluding to the same thing I'm looking for.

    The restart feature of Rise actually does restart the whole player though, so I don't know if it would be necessary for your remote system to restart it again.

    Right now it seems that the restart doesn't seem to be correcting issues that require me to clear the cache. Since the white message issue went across a couple days, the restart feature of all my players didn't seem to fix it. They were only fixed when I remoted into each player and manually did it...then restarted the player, and in 2 displays, I had to go back into Rise and re-publish the presentation (because the whole screen actually showed white on those two...and didn't load anything until I republished)

    Robb, I read both the posts you linked...the first one, I guess I'm a little lost on where it describes criteria that may match my situation?

    And the second link...does that mean that I can create a scheduled task that clears the cache/deletes that folder each day?

    Thanks!

    In the post it goes over how if any of the Placeholders are empty, or are using just a color as the background, they will not show up, you will have to add an empty text item to the Placeholder to make it show up. I don't know if any of your Placeholders met that criteria, so I wanted to make sure you were aware.

    Any objections to me running this Presentation on one of our test Displays here to see if I can determine the issue? Clearly there is something that is still occurring that we need to correct.

    Can you email me a link to the Presentation so I can copy it over to my test Company?

    Regarding the second link, you can create a task that you can run whenever you click it, run as many times a day as you want, whatever works better for you :)
