Your 10g XE server has a default setting for Program Global Area (PGA) of 40MB. The PGA size can be changed to a new value depending on how much data a single session should be allocated. If you think your session will be short with a small amount of data, you should change the PGA size to 16MB by:

Log into the server home page as SYSTEM.
Go to Administration, then Memory.
Click Configure PGA.
Enter the new memory size: 16
Click Apply Changes to save the changes.
Re-start your server.
