Option data captured into database

I managed to capture stock option data into database. I made two mistakes and found the tricks to get it working. The first one was to set expiration Friday instead of the technical expiration Saturday, e.g. stockOption.setExpiration(friday). The second one was to add ib.genericTickList=101,100 setting into conf-base.properties. Below is the IB documentation on Generic Tick Types:
