Is there a discussion forum?

Yes, Kx Systems have been very kind and added us to their 3rd Party section on the kxforums website.

How do I set the look and feel of Studio for kdb+

The look and feel can be set as a command line parameter, e.g for window native look and feel, on a window machine, invoke studio (s4kdbp.exe) using

s4kdbp.exe -J-Dswing.defaultlaf=com.sun.java.swing.plaf.windows.WindowsLookAndFeel

More information on setting look and feel in java applications can be found on Sun's website.

 

When viewing large result sets I get an error telling me to increase the heap size. What does that mean?

Studio for kdb+ is a java application. Java virtual machines generally limit themselves to using a maximum of 64MB of memory. If the java application requires more memory then it is refused by the virtual machine. This can be overcome by increasing the maximum amount of memory allocated to the java virtual machine. This can be done by invoking studio from the command line as

C:\Program Files\s4kdbp\bin>s4kdbp -J-Xmx512m

where 512m is 512 MB ram. Increase this as necessary.
