I am trying to use Portico in one of my projects for sharing objects over the network among the multiple instances of the same application running on several machines.
I am using Windows 7 64 bit.
So suppose there are 3 kinds of objects. A, B, C.
Size of Obj A is around : 300 bytes Size of Obj B is around : 700 bytes Size of Obj C is around : 1200 bytes
I am able to share the objA and objB between the applications. But as soon as I share the objC it throws an error in log that : Error in sending the message of length 1213 bytes. java.lang.OutOfMemoryError java heap space.
I am also tracking my application's heap size in VirtualVM. Following is the info that I retrieved.
While sending objA : Max Heap Size around : 64 MB Heap size : 2.5 MB Used Heap : 1.8 MB
While sending objB : Max Heap Size around : 64 MB Heap size : 2.5 MB Used Heap : 2.0 MB
NOTE here : The heap size shoots to 64 KB but used heap size remains almost same.
While sending objC : Max Heap Size around : 64 MB Heap size : 64 MB Used Heap : 2.0 KB
So, I tried to increase the heap size using the following command :
java -Xms1024m -Xmx1024m -jar portico.jar
but then it threw and error : Error: Could not find or load main class org.portico.rti.Main
Then I tried to compile portico on windows 7 64 bit, it gave me some linking error related to JVM. I am using the latest JDK 1.7. And I was using server VM as client VM is not available in 64 bit.
So I tried building portico on 32 bit windows 7 using client VM. and it build successfully but again I was not able to locate Main class file in codebase\build\java\classes\org\portico\rti\Main.class. And hence, when I tried to use the same command as above along with classpath :
java -cp ......\build\java\classes -Xms1024m -Xmx1024m -jar portico.jar
it again threw the same error : Error: Could not find or load main class org.portico.rti.Main
How do I solve this. It is driving me crazy. Please help me guys.
