Re: Sending data between 4D servers

[Guy Algot]

Randy, Does that require a license for each server?

RE: Sending data between 4D servers

[Randy Engle]

Guy,

Yes, it's old fashioned, but I'm a big fan of using SOAP.
Works great across a WAN.
Very reliable.
Of course the receiving DB needs to be open to Web services.

Pack the field into a BLOB or JSON object and send 'em!
Unpack on the other side.

Subject: Sending data between 4D servers

Given v15s current tickle trunk of features, what would be a good way to send 
data between servers across the WAN?

In the past, I’ve done it by bundling up the data in a BLOB and dropping it on 
a secure FTP site. Any better, faster, stronger methods one prefers? Thanks.

Later,
Guy

Re: Sending data between 4D servers

[Guy Algot]

Hi Kirk,

In this case, it’s specific fields from one database + some pictures. The 
databases are not the same and its not a sync. When a record gets updated, the 
new data is moved (pushed or pulled) to the other server. I expect it to happen 
on a daily basis. The data is fairly small although some of the pictures can be 
a couple of MB.

I’m not a fan of ODBC and one of the computers is a Mac. I’m ok with the 
watched folder idea but I thought there might be something else people were 
using. I had thought about using SQL LOGIN but I’m not sure how it handles 
picture data and it looks like it does not work reliably across versions.

We use SQL to mover data between different servers running the same
application all of the time.

At San Antonio summit, I demoed a clone utility that will help get you
started.

Hope this helps. If you like I could probably post code to github upon
return from vacation

Regards


Chuck

Re: Sending data between 4D servers

[Kirk Brooks]

Guy,
Interesting scenario. A couple of thoughts come to mind.
What kind of data? Are these two instances of the same database that need
to sync somehow? If so how fast does it need to happen? Is this a
'discussion' with each db sending and receiving or more of 'fyi'? And how
much data are you looking at?

I have zero experience with ODBC so no idea if that would be good. I
suppose you could agree on some obscure ports and use send/receive packet.
Or use http calls between the two. This would give you a real-time
connection. If you don't need that I'd go with setting up the 'watched
folder' idea and some sort of disk file.

If the source server can connect to the target one, I've made something like 
this last year with SQL. It's hard to say that it will be faster than an 
intermediate text file… Source and target share the same structure?
