One more question...if I do use a tool for replication and I only have the indexer running
on one machine...say it creates 10 file *.cfs...the tool replicates all the files...then the
machine with the indexer compresses those files and then are now all gone...how will they
be removed from the slave machines?

My webmaster sent me this:

He has used this...can I assume this would work just as well?

Hi,

Replistor makes a byte to byte copy to the slave machines from the Main
PC.  We use it to replicate a SQLServer Database to a standby PC (it
does a byte to byte copy), it also sync's our web application changes
across the web farm.

Never seen this product...but in my case I would have the indexer
running on one webserver and the second it creates a file, Replistor
will take care of getting to all the other machines...but will there be
any issues with compressing etc.? I have come across where .cfs files
were missing etc.

Hi,

    You might want to use Replistor in a case like this and only have
one indexer running, let Replistor manage the copies.

Subject: Java Indexer + DotLucene + IIS question

Hey-
 
I have the following situation, and I am looking for any suggestions...
 
First, here is my current configuration:
 
1. Java Indexer (windows service) created to index data from a SQL
Server database...3 indexes are created
 
2. DotLucene is used on the front-end to search my index files...which
means I am running on Windows Server 2003 and IIS 6.0 ( sorry guys :-P )
 
3. The index location(s) are read from a config file
 
4. I am currently running this site on one webserver (not a farm)
 
The problem is that I am moving to a webfarm shortly...and I am trying
to figure out a way to replicate the index(s) that I am creating. The
indexer indexes based off a bit field in the database, and a seperate
thread runs in the background to optimize the index(s). 
 
Possible Solutions: 
 
1. If I use so me built-in replication or some other third party
solution across the servers I think (tell me if I am wrong please) I may
have an issue since the indexer compresses and writes and something may
go wrong...
 
2. If I use a shared drive (UNC) to another clustered machine (not one
of the webservers), I need to open ports for IIS and the worker process
to talk to it...not a good idea
 
3. If I store on one web-server and have a shared drive from all other
webservers to that one webserver, then I have a problem if that one
webserver goes down for aby reason
 
4. I don't want to store the indexes in a database
 
5. I can get a Index Server to use (like a state server)...but I would
rather not spend the money :-)
 
6. I can use some remoting solution to bypass the UNC idea...but this
requires a coding change (not a problem if this is the best solution)
 
 
What I am looking for is someone who knows of the best solution...or if
someone implemented something different than the above.
 
Thanks!
-Joe
