  2. Find the following line in the document:
  3. Combine all the specified options into the JAVA_OPTS variable.
  4. Add the following line below the above-mentioned line to set the size of heap memory:
  5. Add 512 megabytes as the initial memory allocation for Java and increase the maximum memory allocation to 1024 megabytes.
  6. “Here, -Xms stands for setting the initial size of the heap, and -Xmx stands for setting the maximum size of the heap. In this example, the initial size is set to 512MB and the maximum size is set to 1024MB. You can modify according to your own requirements.”
  7. Save and close the file.
