Data / Data files / Database GROWTH

Question

Dear experts,
I have a practical question on reading / determining the exact fluctuations in the sizeof
a database.
I am publishing this question in the oracle section, as my database is oracle, but if I am
not wrong, all this should be valid for all databases.
So, the question itself: I have a system, where all the datafiles / tablespaces are set to
AUTOEXTEND, the size for each growth is 200 MB (meaning, if growing automatically,
the increment size will be 200 MB). Now I would like to see, if datafiles grew automatically,
lets say for today! And if yes - by how much increments.
Furthermore, I would like to ask - browsing ST04, in Space / Database / Overview on the
history tab - all the daily / weekly / monthly changes - how to evaluate, whether this was
only an "internal" growth, when the database grew in account of decreasing the free space
in the DB itself, and when it has also caused a data file to grow automatically, as it has its
AUTOEXTEND option enabled ???

Answer 1

Dear Deepak,
after quite a lot of googling,I found this:
SELECT TO_CHAR (sp.begin_interval_time,'DD-MM-YYYY') days, ts.tsname,
max(round((tsu.tablespace_size* dt.block_size )/(1024*1024),2) ) cur_size_MB,
max(round((tsu.tablespace_usedsize* dt.block_size )/(1024*1024),2)) usedsize_MB
FROM DBA_HIST_TBSPC_SPACE_USAGE tsu, DBA_HIST_TABLESPACE_STAT ts, DBA_HIST_SNAPSHOT sp, DBA_TABLESPACES dt
WHERE tsu.tablespace_id= ts.ts#
AND tsu.snap_id = sp.snap_id
AND ts.tsname = dt.tablespace_name
AND ts.tsname NOT IN ('SYSAUX','SYSTEM')
GROUP BY TO_CHAR (sp.begin_interval_time,'DD-MM-YYYY'), ts.tsname
ORDER BY ts.tsname, days;
It comes the closest to what I really need. And what I need, is the above query,
but by data file, not by tablespaces.
Thanks a lot!!
