XMX

The flag Xmx specifies the maximum memory allocation pool for a Java Virtual Machine (JVM), while Xms specifies the initial memory allocation pool. The memory flag can also be specified in different sizes, such as kilobytes, megabytes, and so on.

The default values for Xmx is based on the physical memory of the machine. The Xmx value is 25% of the available memory with a maximum of 25 GB. However, where there is 2 GB or less of physical memory, the value set is 50% of available memory with a minimum value of 16 MB and a maximum value of 512 MB.

To configure java heap size values:

1. Log into web console.
2. Click Administration and go to Settings > Memory.
3. Specify the maximum memory allocation pool (Xmx) and initial memory allocation pool (Xms) values for the JVM in the respective fields.
4. Click Save.

Setting -Xms and -Xmx to the same value increases predictability by removing the most important sizing decision from the virtual machine. However, the virtual machine is then unable to compensate if you make a poor choice.

Task Engine runs on JVM (Java Virtual Machine). By default, the JVM heap size is 1GB, which is usually enough to accommodate the data used by Task Engine. However, larger heap size may be required under some circumstances, for example, when the average size of the parameters in a task is very large.

The short answer is that you use these java command-line parameters to help control the RAM use of application:

1. Use -Xmx to specify the maximum heap size.
2. Use -Xms to specify the initial Java heap size.
3. Use -Xss to set the Java thread stack size.

The Xmx Command Line Option. The Xmx option is used in the command line to set the maximum heap size that is to be used by the Java application. The Xms option is used to set the lowest heap memory that is to be used by the application.

The flag Xmxspecifies the maximum memory allocation pool for a Java Virtual Machine (JVM), while Xmsspecifies the initial memory allocation pool. This means that your JVM will be started with Xmsamount of memory and will be able to use a maximum of Xmxamount of memory.

The above Xmx flags allocate the Java heap memory to a maximum size of 80MB. Note that there is no space between the flag (-Xmx) and memory size (80M). It does not matter if you are using an uppercase or lower-case letter.

The flag Xmx specifies the maximum memory allocation pool for a Java virtual machine (JVM), while Xms specifies the initial memory allocation pool. This means that your JVM will be started with Xms amount of memory and will be able to use a maximum of Xmx amount of memory.
