Hi All,
I am looking for a guide which can help in deciding the required network bandwidth between the master and replica sites.
Has anyone gone through such guide?
Thanks,
~Amit
I recently configured 4 replica sites for a customer, PTC's documentation on replication is not so deep and It was such a pain to achieve acceptable rate of success of the replication process, I didnt found any guide talking about bandwidth, but found out some hidden preferences and apache/tomcat/database tweaks that with moderate thinkering will help you to achieve good replication (around 95% of success in each replication process) in any bandwidth.
In this particular customer, thay had very poor internet connection between the master and the replicas, once the replicas were located in remote construction sites with only radio technology for connection. I was having massive packet loss, had to tweak apache, tomcat and windchill regarding timeouts and after that had to create indexes to increase replication speeds.
One thing that looks like is not working yet is the "scheduled replication" process, in a regular replication process, if a document fails to replicate (due packet loss or anything) it will be labelled as failed and windchill would try to replicate it the next day again. That is not working for me, everyday I have to manually reset failed replication items through vault configuration UI.
Below is the info I've saved in my evernote account for future reference, it was copy pasted from different places so the information is not so well organized.
You are in luck cause some of the preferences bellow was so hidden even first level PTC customer support didnt know about it and they are not in knowledge base, at least it wasnt, I had to escalate the case some times to find those out, tooked me like 1 month to gather the info bellow.
I hope it helps you and that you doesn't have such pain I had.
best of luck!
wt.properties Options to play with, values really depends on your actual bandwidth and stability of it, I still doesnt have a perfect combination of values for this preferences, it really is a try and check results process.

“A goal without a plan is just a wish.”
We can certainly use the information in this thread to enrich our documentation for replication. In addition, there is an Enterprise Deployment Center document entitled "Windchill Vaulting and Replication Planning - Technical Brief"; this document addresses scalability of the solution, talks about bandwidth considerations, and identifies important Windchillproperties. You can find it here:

I'd appreciate any additional feedback you have regarding documentation requirements for this Windchill capability.
Thanks,
Jane
