如何从 java 更改 scala 中的 actor.maxPoolSize？

Question

So I have two bash scripts. One for calling the bytecode using the "scala" command, the other to call the same code using the "java" command. My problem is the following, when I use scala, I can see that I can get about 80 threads ( which I created, and shows in my "Task Manager" ) while when I use the java command, I only get about 20 threads created. instead of 80. What is the equivalent "define" option under java for actors.corePoolSize and actors.maxPoolSize?

These are my bash scripts. The first has the following:

JAVA_OPTS="-Xmx1g" scala -cp bin com.mcmc5.Main -Dactors.corePoolSize=60 -Dactors.maxPoolSize=5000

the second has:

java -cp scala-library.jar:bin com.mcmc5.Main -Dactors.corePoolSize=60 -Dactors.maxPoolSize=5000 -Xmx1g

Answer 1

As far as I know, you can set System Properties in your application:

System.setProperty("actors.minPoolSize" , numberOfActors)
System.setProperty("actors.maxPoolSize" , numberOfActors)
System.setProperty("actors.corePoolSize", numberOfActors)

Answer 2

The way you have defined your properties using java looks fine. Have you considered setting the actors.minPoolSize property? This is exactly how I configure my actor-based applications.
