title: Oracle - Adding columns to a table takes forever
body: <p>I need to add two DATE columns to an already existing table. But it takes very long and I have to kill the process. What is strange is I was able to add those columns to the other tables in the same database momentarily. Most of those tables are larger than the one I'm having trouble with both data and column-count-wise. What do I have to do to be able to add those new columns?</p>
