This tutorial will introduce to you the most productive approaches to solve the error occurred during initialization of vm could not reserve enough space for 2097152kb object heap. Let’s dig in!
What Causes The Error Occurred During Initialization Of Vm Could Not Reserve Enough Space For 2097152kb Object Heap
This error message could appear when you start Talend Studio or perform a Job. As such, the Job will occasionally crash and produce an error when you set the -Xmx Java VM argument to provide a Job execution extra memory.
This leads to Talend Studio not being able to launch or the job is incapable of execution. Take a deeper look and you will see the root cause of this problem is the available memory being insufficient for the maximum heap size given by the -Xmx argument.
How To Fix The Error?
Method #1: Making Use of Command-Line Options
If you attempted to launch Java and saw this warning, you have presumably previously used the free command to ensure that there is enough memory available for the application to execute in.
Close any other programs you have open if you find that you are getting scarce on memory before testing it again.
For those people who discovered they had a lot of spare RAM, you may feel free to explicitly define a size.
Take this situation as an example. We were able to run the command as java -Xms256m -Xmx512M on our system, and it performed as expected. This limits the amount of heap space that the Java virtual machine tries to set aside at startup.
An unfettered virtual machine could produce error messages on an otherwise unrestricted system since it theoretically might perform strange things. To discover the ideal setting, you might wish to experiment with those two variables.
Method #2: Reduce The -Xmx Parameter’s Maximum Heap Size.
This error will appear if the huge heap size you set exceeds the physical memory that is available on the 64- or 32-bit computer.
For instance, if your computer has 3 GB of RAM and you try to run the program below, you will see this error.
java -Xms4096M -Xmx4096M MyApplication
The program can be executed with a heap size that is less than your actual memory. Follow the example below:
java-Xms2048M -Xmx2048M MyApplication
Method #3: Utilizing A 64-Bit Operating System
Since the maximum heap limit for a 64-bit JVM might be substantially larger, there is a great way for you to employ it so you can solve such a tricky problem.
All you need to do is to install Talend Studio on a 64-bit operating system or migrate the job script to a 64-bit operating system to execute. There you go to have your path already paved!
