image - How do I fix "java.lang.OutOfMemoryError at sun.misc.Unsafe.allocateMemory(Native Method)"? -

-

I am a Java application that uses the library to load images. However, on some computers, I get this error when the program is trying to run: 

  formula exception "main" java.lang.OutOfMemoryError on sun.misc.Unsafe.allocateMemory (Native resident method). Init & gt; (DirectByteBuffer.java:99) Org on java.nio.DirectByteBuffer organization on java.nio.ByteBuffer.allocateDirect (ByteBuffer.java:288) org.lwjgl.BufferUtils.createByteBuffer (BufferUtils.java:60) & lt. newdawn.slick.opengl.CompositeImageData.loadImage (CompositeImageData Java: 43)

I VM options: 

 -Djava.library.path = lib -Xms1024M -Xmx1024M -XX: PermSize = 256M -XX: MaxPermSize = 256M

the program some large images in the beginning (1024 x 768 resolution) loads.

Any help to solve this problem would be greatly appreciated.

Op = "text">

Just indicates that the JVM has gone out of memory The first line of the stacktrace is actually relevant here it just happens as "not" by chance actually there where you run out of memory with JVM collect all the garbage in vain, initially.

There are basically two solutions:

  1. Provide more memory.
  2. Fix memory leaks and / or assign less memory to the code (i.e., the code is more efficient, very long and so similar) to the large byte [] Like the memory does not get hold of expensive resources.

Point 1 is easy to do but is not always a solution, if it is apparently the leakage of memory in the code, point 2 is best to move down with A.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
