Hello,
first of all tank to both of you for your fast response.
Going back to Michael's wonderful ASCII art masterpiece, what we have now is
something like this:
------- JVM -----------
---- JAVA ----
JDBC
|
|
Algorithm
|
---- JAVA ----
------- JVM -----------
|
RNI
|
R
What we want is something like the following (on the same virtual machine):
------- JVM1 ----------- ------- JVM2 -----------
---- JAVA ---- ---- JAVA ----
JDBC JDBC
| |
| |
Algorithm Algorithm
| |
---- JAVA ---- ---- JAVA ----
------- JVM1 ----------- ------- JVM2 -----------
| |
RNI RNI
| |
R(1) R(2)
My question is: is that possible ? How can I address R(1) from JVM1 and R(2)
from JVM2 ? Is data calculated in R(1) and R(2) completely independent or the 2
instances "share" something in memory ?
Thanks again for you kindness and help.
Angelo

I think he means driving the R framework from Java via JNI. I think
the questions boils down to whether you can open multiple independent
R sessions on the same system and then address them separately via JNI
(I don't know, but I would assume you can do that without multiplying
the installation).
Take care
