Hello All!

I created a tablespace for my rollback segments at the initial install of my instance like so:

create tablespace RBS_1 datafile 'yada/rbs01.dbf' size 100M
reuse autoextend on next 5120K minimum extent 512K
default storage ( initial 512K next 512K minextents 2 maxextents 4096);

I have 12 rollback segments using this tablespace. Well, my tablespace size has expanded to almost 2Gb.

What did I do wrong and how do I fix it? Also, how do I shrink my tablespace size back down?! I 've been doing some research, but I'm skeptical about trying anything because I'm afraid of messing up the instance.

Thanks in advance!!
