Portal Config Assistant and resize of tablespaces

Question

I am new to Oracle, and I am trying to install Oracle9i AS on Oracle8i. My problem is: Portal Configuration Assistant gives me an error during step #5. It says that my default tablespace of my database is too small in size. I need to expand it or to set autoexpand. I don't know how to do that.If it's not too much to ask, can you, please, give me step-by-step guide for changing this parameter. Also I know I have to start CQL Plus, but I am not sure what is my host string. Please, help me.
Thank you,
Ivan.

Answer 1

Log in to SQL*plus as a DBA (try system/manager)
type the following statements in..
column file_name format a55
column tabespace_name format a20
column filesize format a15
set lines 180
set pages 999
select file_name,
tablespace_name,
((bytes/1024)/1024)||' Mb' FileSize
from dba_data_files;
You should get something like this..
