How big is the ResultSet?
By default the JVM alocates 64Mb of memory. To increase this, you pass the
-Xmx parameter to java, ie:
java -Xmx32m my.app.classfile
where 32m is 32Meg of memory maximum.
From SUN's docs:
-Xmsn
Specify the initial size, in bytes, of the memory allocation pool. This
value must be a multiple of 1024 greater than 1MB. Append the letter k or K
to indicate kilobytes, or m or M to indicate megabytes. The default value is
2MB. Examples: -Xms6291456 -Xms6144k -Xms6m
-Xmxn
Specify the maximum size, in bytes, of the memory allocation pool. This
value must a multiple of 1024 greater than 2MB. Append the letter k or K to
indicate kilobytes, or m or M to indicate megabytes. The default value is
64MB. Examples: -Xmx83886080 -Xmx81920k -Xmx80m
