My experience from the latest upgrades are that the database will
grow by 10% when upgrading from 5.5 to 6.2.2.2.
2 days ago upgraded a 5.5 server to 6.2.2.2 and this happened
with the database size:
**************************************************
*** ---> Q DB F=D from TSM 5.5
**************************************************
Available Assigned Pct Max.
Space Capacity Util Util
(MB)
--------- -------- ----- -----
120,000 120,00 74.2 74.2
This is 120GB*74.2% = 89GB used
**************************************************
*** After the upgrade to 6.2.2.2
**************************************************
Database Name: TSMDB1
Total Size of File System (MB): 737,233
Space Used by Database(MB): 97,216
All the upgrades I've done during the last 6 months show the same pattern.
When TSM 6.1 was released IBM said the DB would grow approx. 3x (300%),
but that doesn't seem to be the case today.
Of course if you start adding features like dedup the DB will grow. I
have one installation that was 40GB in 5.5 and today is around 800GB.
This growth is mostly caused by dedup (add 1TB of DB disk and save 75TB
of stgpool disk....)
