Re: IBMi --> MS SQL Server Connection

Hey Dieter, thanks for your comments. I am exploring your work on
AppServer4RPG.
Java knowledge is no problem at all. Embedded RPG has been my essential
experience for many years, even ILE C programming has been too.
You have said the exact intention: pull up the image's binary stream, put
it on an IFS folder and then send it back as MIME type "image/jpeg" or
whatever, either by sending the whole stream or by a "Location" http
header. There are options for that.

Testing your tool is what I'd like to do. What I would need is, where can
I find more information, as sample usage code? Is that in the same
project's site?

Thank you very much!

@ArdGate (AppServer4RPG)
ArdGate is based on IBM's "client integration exit" and this doesn't
support
BLOB/CLOB. As a conclusion of this you can't get images with embedded SQL
via ArdGate.
@Infosphere: this would need an additional p-series as server in the
middle - and might be very expensive, ask your ibm representive.

Using RPG/Java Mix via JNI (Scoott's open source included), you should
have
in mind, that starting a JVM is time consuming and starting lots of JVMs
limits scalability. AppServer4RPG is a Framework to make calls from RPG to
a
single prestarted JVM with high speed and (nearly) unlimited scalability.
It
could be extended for your needs - but Java knowledge is a must have.

There is a work around with ArdGate: use embedded SQL from RPG to put the
image in a temporary streamfile on a shared drive to move it from MSSQL to
your AS400 (or i or whatever). Some MS SQL knowledge would be needed
anyway.

Assistance would be possible, but might need some money, depending on
effort.

Maybe MS SQL linked server could be another option.

To connect from IBM i to SQL Server all you need is a JDBC type 4 driver
for MS SQL Server...

Then you have to decide how to invoke it
- From a Java program
- through a DRDA Gateway
- Directly from RPG

I wouldn't recommend the last option.

For the second option, you've got the following choices...
purchasing and installing an external IBM Infosphere Federation Server
Or locally install on your i a DRDA Gateway product
- the commercial https://razlee.com/isecurity-db-gate/
- the open source https://sourceforge.net/projects/appserver4rpg/
