Full database import hangs

Question

System:
Windows 2000 SP4
Oracle 8.1.7
Hi,
I am importing a full backup ( export dump file ). It was taken from the
database having the same structure as the database to which I am importing.
It is taking too long in importing data in a particular table and seems to hang
for hours. It says 40542226 rows imported. It seems to hang from here.
I checked the v$session to identify the session serving the import and
v$session_wait to verify the wait events for that session. But I don't see
any wait events for this session. What I see is the session itself.
I did the import using:
imp username/password@sid file'D:\data\fullbkp.dmp' log=D:\log\fullbkpimp.log' full=y
My question is: what are other diagnosis I should perform to help find out the cause and
possibly the solution of this import hang?

Hi,
In addition, when I want to see what's is going on, I usually execute the SQL below in order to monitory the import operation activity...
select substr(sql_text,instr(sql_text,'INTO "'),30) table_name,
rows_processed,
round((sysdate-to_date(first_load_time,'yyyy-mm-dd hh24:mi:ss'))*24*60,1) minutes,
trunc(rows_processed/((sysdate-to_date(first_load_time,'yyyy-mm-dd hh24:mi:ss'))*24*60)) rows_per_min
from sys.v_$sqlarea
where sql_text like 'INSERT %INTO "%' and
command_type = 2 and open_versions > 0; Cheers
