Limitations

The default limit on open cursors per session in most Oracle installations is 50, which is also the default limit for our interface. There is also a limit imposed by the XSB interface of 100 cursors, which can be changed upon request ^7.1. If your Oracle installation allows more than 50 cursors but less then 100 then change the line

 
#define MAX_OPEN_CURSORS 20

in XSB_DIR/emu/orastuff.pc to your new value, and uncomment enough many cases to match the above number of cursors plus one, in the switch statements. Currently this number is 21. Then re-build the system. In XSB_DIR/emu/orastuff.pc we provide code for up to 100 cursors. The last 80 of these cursors are currently commented out.
