DB2 9.5 How to get tablespace monitor information?

Question

How can I get information about tablespace in DB2 9.5?

I need to review information about if the autoresize option is enabled or disabled.

Answer 1

Use the TBSP_UTILIZATION administrative view - Retrieve table space configuration and utilization information. See the "Essential DB2 Health Check" for a recommendation on how to use it, especially the sections on File System Free Space and DMS Tablespace Free Space.

Example:

select substr(tbsp_name,1,10) "Name", tbsp_utilization_percent "Used%", tbsp_free_pages "FreePages", tbsp_usable_Pages "UsablePages", tbsp_used_pages "UsedPages", tbsp_page_top "HWM", tbsp_auto_resize_Enabled "AutoResize 1=Yes", tbsp_increase_size "Increase Size", tbsp_max_size "MaxSizeBytes -1=ulimited", tbsp_last_resize_failed "ResizeFailed 1=Yes", tbsp_page_size "PgSize Bytes"
from SYSIBMADM.TBSP_UTILIZATION
where tbsp_type = 'DMS';

Specifically, you are after the tbsp_increase_size field from the SYSIBMADM.TBSP_UTILIZATION table, where tbsp_type = 'DMS' as show in the query above. (The query has a few other things that are helpful in it too.)
