Separate the Creo saved files from the Windchill cache.

Separate the Creo saved files from the Windchill cache.

What is a cache?  A temporary, volatile, and expendable storage area so the same data doesn't need to be downloaded repeatedly.  So why is Creo saving its files there when it's connected to Windchill?  Whenever anything goes wrong, tech support says to delete the cache.  That deletes your saved work, too!  There are times you cannot access your work because the cache is messed up and has to be deleted to even launch Creo, so PTC then points you to a user created recovery tool. 

 

How about this:

 

Store cached data in the cache.

Store saved data somewhere else!

Set up Windchill so it does a Save and Upload. Then your files are on the server workspace and no long dependent on your local machine cache.

 

I have been using Windchill since 6.2.6 with Proe/2001 and am now on Windchill 11.0 m030 and Creo 4.

I have never had a cache file corruption in 18 years!

Are you a single user, or do you support a group of users?  I have many single users that have not reported corruptions in my 12 years, but in a large set of users, they do happen.  They used to happen frequently on Windchill 7 and 8.  Much less frequently, now, but they do still happen.

 

Setting Creo to Save and Upload every time is one way to provide redundancy, but it is not practical in all cases, and causes a performance hit.  Our Windchill is in the PTC Gov Cloud, and the performance and reliability is not anywhere near what it would need to be to make use of that.  Either way, it doesn't make sense to store important saved files in the same way that temporary unimportant files are cached.

I am a system admin for multiple users ranging from 6 users to 250 users over the years at 3 companies.

We have always used Save and Upload and when run in a local environment, we do not see any performance issues.

In a local environment it would work better.  In the cloud we have to go through the internet to get there, and are also limited at PTC's end, so speeds range from 0 to 20 Mbps per stream.  Even with uploading all the time, it makes sense to separate saved and cached data.
