Sun Solaris 10, Oracle 11gr2 x86 How are you doing? I am trying to build a test system. I never build ASM before. if I need to install database first then Migrating to ASM? The other problem I am having is that I only have a Raw disk. I have one disk for root and oracle and the other one for Raw disk for ASM. Do you know it's possible to build ASM on 1 raw disk?

what is the Minimum datafile size required for creating a non-system tablespace?
I am trying to create a tablespace by giving the syntax like,
SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 72k;
create tablespace t1
*
ERROR at line 1:
ORA-03214: File Size specified is smaller than minimum required
SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 73k;
Tablespace created.
The blocksize for my database is 4096, as i have heard that the minimum size of the datafile is decided by blocksize, but i want to know that how it is calculated as by giving the above syntax the other values will be default. I am trying the syntax in oracle 9.2.0.1.0 version.
I'm currently new to Oracle 10g SQL and I need to query a large library file.I need to find the different first keywords associated with references written by authors who have more than 10 references in the readings table.

I have been reading various articles about the undo management. This basic concept of undo management is simple but how oracle implements it is bit harder for me to grasp.
What i have read and understood is that whenever a DML(Update, Delete, Insert) statement is issued by a user, the data is fetched from datafile to database buffer cache and at the same time a copy of the original data is saved in undo segment. Now if other users requests the same data, they are presented with the unchanged copy in the undo segment.
Now I have the following questions:
1) In case of Insert statement, what data is saved in undo segment. Is it the complete data in the table to which we want to insert the new row?
2)When the user issues DML statement, there are three copies of the same data, one in Memory (which is changed and not the same as original data), second in Undo segment (Which is unchanged copy of original data) and third in datafile file ( which is original data). What is the difference in the data in undo segment and data in datafile at this stage. Why are the other users presented with the data from undo segment rather than original data from the datafile to maintain read consistency.
3)When the user issues rollback, the changes made to the copy of data in memory are undone.The copies of data in memory and undo segment are now same?. What happens to the before change copy in undo segment. Is it still there or deleted.
