RE: Postgres JDBC Driver : java.lang.OutOfMemoryError

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

The ODBC drivers work. If you want to run the server under NT you'll
need CygWin in practice.
