Sharon, Thanks I did not think it was released yet. When I spoke to them, they said it was still in testing.

This is the kind of corruption where fields/labels/etc. are in weird spots. I just downloaded it and will be testing/QA'ing in my environments soon.

Even if the server isn't finished syncing yet the login process shouldn't care. If syncing was as hard on a system as a cache rebuild then I could see timeout issues occurring. You could probably tail the Mid Tier logs to see what is happening during a sync (depending on your logging settings). I have tailed the log when flushing cache but not syncing cache. The only way I know of seeing if a person is using MT or WUT is either 1) using workflow to capture it (in a record) or 2) watching access logs on the web server. I guess one other kind of goofy way is to tail the aruser.log. Since 7.6.04 or so when a user is using WUT there is a ton of logins recorded vs. when a user is using MT. If you see the same person logging in every few seconds then they are using WUT. On our environment where WUT is primarily used the aruser.log grows very rapidly. I choose always allow as well for pop-up blockers. Basically you want to trust any page MT is going to throw at you. It has been so long since I have read the message that I don't even remember what it say. Clicking the always allow happens from muscle memory at this point :) Jason On Fri, Oct 11, 2013 at 7:24 AM, Susan Palmer <[email protected]<mailto:[email protected]>> wrote: ** I tried sync cache last night and it seemed a bit faster but still took at least 10-15 min. I have noticed that after a sync I have issues logging back into mid-tier which I assume means the sync is not done. Is there a place to watch what it's doing? Different question: Can you see who is logged on via the mid-tier as opposed to client tool. License review just shows everyone. Different question: Pop-up blockers. A bit confusing, it says 'don't have pop-ups active, then later it say it wants pop-ups. I actually had misread the 'don't allow' message wrong initially and had chosen 'always allow' and didn't see any ill effects of that.

How often are definition changes made in your production server?....Weekly? Monthly? Quarterly? You likely don't need an automated 'check' to be turned on in production as it doesn't change very often...and when it does, you can manually hit the 'sync' button. Regarding the app server being behind a load balancer...no, that won't affect things because regardless of which app node the mid-tier gets the cache from, it should be 'correct' :) On Thu, Oct 10, 2013 at 2:45 PM, Joe D'Souza <[email protected]<mailto:[email protected]>> wrote: ** I won't pretend to answer this question for you - but this is my guess.. >From what it looks like, this functionality performs a periodic check on the >AR Server, to check for changes in definitions, and collects that information. >This will in my opinion have some impact on performance. So as long as that interval is relatively high, and set in such a way that it occurs in periodic cycles when users are usually not online, it should be fine. My guess is that when this box is checked and the interval is defined, there is probably a definition check that happens that instant, followed next by the interval that is defined. So if this is done lets say at 11:00 PM when most users are usually offline in that time zone, and the interval is set for 86400 for the next check to happen at 11:00 PM the next night, you might not have too much to worry about. I would however not be comfortable doing it every few minutes, as it MAY impact the performance of that particular mid-tier server in that load balanced configuration..

When the dev and production ITSM servers were installed Perform Check was no selected. Don't know why it was done that way. Later when I applied a patch to the mid-tier servers, BMC Support said I should select Perform Check. I did this on the development server which has one ar server, one mid-tier and no load balancers, but did not select Perform Check on production which is a VIP > load balanced to two mid-tiers which are load balanced to two ars servers in a server group. Particularly with small changes I really like using change check/perform check on dev and would like to use on the production servers. Since I don't know why this was not originally set up that way I figured I would ask the group first.
