Altering a Large Table

IDS 10.0 FC8 I'm wondering if there is a trick to altering a large table without running into a large transaction. I'm trying to add a char(2) field to the end of an existing table - it has 23 cols and about 12 million rows. The total table size is about 2.5 GB, there is 4GB of logical logs. I'm running the following alter command in dbaccess; alter table address add add_source char(2); Is there a trick to doing an in-place alter?
