Question

Are there replication functions to suport two side updates of same WebHome in two Server?

NFS mounting is a good idea. But it is slow.

rsync is good a idea. But there may be lost.

two different WebHome is ok. But can not mix up the two sides.

One server only, it may be two slow in one side.

.

• TWiki version:
• Web server:
• Server OS:

Some Pointers

I don't think anybody has a complete answer to this (I might be wrong), but you can find some ideas and information in: WikiClusters, DistributedTWiki, ReadWriteOfflineWiki, MultipleCommitPathBehaviour, OfflineWiki, and PackageTWikiStore.

Answer

I know MichaelSparks has been working with this problem and has gone a long way down the road of getting an rsync based solution to work. He says somewhere that once TWikiReleaseSpring2001 has been released he will work on folding his changes into the public version.

So, I guess if you want to help make that happen the most useful thing you can do is beta test the next release

Clarifying the question:

I'm a little uncertain as to what is being requested, I sense that you (Ben) may be asking for a way to replicate a twiki between two sites, but allowing each site to have it's own (unique) WebHome pages?

Hi, As MartinCleaver indicated above, I have been working on this, and now that (finally! :-))) ) the new production release is out, I'm now working on folding our local changes to do replication between 3 different geographies (all with local owned content and local editting/viewing as well as replication) DistributedTWiki describes what I'm aiming for and DataAndCodeSeparation describes the changes necessary to a twiki installation to make this simple/trivial to setup. However the changes to the twiki installation are pretty major - but IMO worthwhile, so I'm working at the same time on an installer to make life simple for this.

Longer term I'm looking to have an "edit anywhere" setup, which will require in many respects a different model from rsync, and will be aiming towards a CVS based setup. (NB this isn't for local change control, the main twiki code would remain unchanged - this is for simple merge conflict reasons which I don't want to rewrite the wheel for, and also it will be a "bolt-on", rather than core Twiki-code)

For now though an rsync model IS working very for us with multiple Twiki servers, and multiple Twiki webs owned in multiple locations. (About 1/2Gb of content now being managed via Twiki this way which isn't too shabby, but I bet nowhere near a large install yet )

I am interseted in setting up DistributedTWiki . To whatever level possible (edit anywhere, over CVS/rsync). Currently using 01 Dec 2001 version of Twiki. Could not find any directions so far, rather than probably reinventing the wheel. Please help.
