		hello 
I'm a programmer having to take on DBA responsibilties. 
 
We have a database that consists of approx 7gig storage 
that is located in the Pledgemaker Tablespace. 
 
The past couple days the performance seems very 
slow and labored. We do alot of transaction processing 
throughout the course of an 8 hour day..plus 
we have managers running queries and reports on large 
volumns of data. 
 
The following represents the current state of the db: 
 
SQL> @free 
 
TSNAME                           PCT_FREE 
------------------------------ ---------- 
PLEDGEMAKER                        892.16 
ROLLBACK                              400 
ROLLBACK                              100 
SYSTEM                              64.01 
TEMP                                  900 
TEST                                  100 
 
6 rows selected. 
 
SQL> @spacebound 
 
no rows selected 
 
SQL> @dbgrowth 
 
Month          Growth in MG 
-------------- ------------ 
2002 December          2000 
2002 February          1000 
2002 May               2000 
 
======================================================= 
 
I would be very much obliged if someone could explain, 
in simple terms, how to go about analyzing and optimizing a db. 
 
also..is there a way to create a second instance 
of the db where users can do OLTP on one instance 
while managers can run reports & queries on a 
second instance without both needs causing hangups 
and conflicts with one another. 
 
thanks in advance.
