Help - Database Growth and loading best practice

[Former Member]

Dear all,

I'm using NW 7.1

my data are consuming lots of space. I notice my data are grow at 20Gb per 2 month.

I wonder why the growth is so fast.

I using process chain to load my data and I always delete my data before full update my cube.

I kept only 1 week worth of data in my psa.

I do upload all my master data daily. ( full and delta upload )

Please advice

Regards,

Hi Dedy,

Its difficult to answer your question without some stats. use Tcode DBACOCKPIT to analyze different table spaces, by using option Space> Tablespaces or Space>Tables and Indexes. This will help to understand which tablespace / table is growing significantly and wil help you take necessary actions accordingly.

Let us know, your findings and if you need more help.

Cheers,

As BI consultant we were keen on PSAODS table which relates to PSA and changelog tables

Your system tablespace shows 99% full. You should plan on allocating more space to SYSTEM.

Run this SQL statement in SQLPLUS (you can also use ST04 to gather this info)

SELECT SUM(BYTES) from dba_segments

where segment_name like '/BIC/B000%' ;

Can you tell us the result of this statement?
