How did you run reorg online or offline?
Use reorg command with "USE" keyword and specify any SMS tablespace
which had good space to hold reorg.
Even if it does not lower the high water mark pages, try using DB2DART
utility with exclusive connection to db.

Rajesh

Hi

We have 4k Tablespace that is nearing the 64gig limit. There are only
two tables in the tablespace. A very small Codes table and an events
table.
To avoid running out of space we deleted about 60% of the rows out of
the events table.
A reorg was run on the table, but no pages were freed up.

How can I see the amount of pages freed up .


The out of list tablespaces show detail before and after the reorg

Before:
Tablespace ID = 4
Name = PRD_EV_DAT
Type = Database managed space
Contents = Any data
State = 0x0000
Detailed explanation:
Normal
Total pages = 15976876
Useable pages = 15975936
Used pages = 14952960
Free pages = 1022976
High water mark (pages) = 14952960
Page size (bytes) = 4096
Extent size (pages) = 128
Prefetch size (pages) = 512
Number of containers = 4
Minimum recovery time = 2005-03-08-13.23.35.000000

After:

Tablespace ID = 4
Name = PRD_EV_DAT
Type = Database managed space
Contents = Any data
State = 0x0000
Detailed explanation:
Normal
Total pages = 15976876
Useable pages = 15975936
Used pages = 14952960
Free pages = 1022976
High water mark (pages) = 14952960
Page size (bytes) = 4096
Extent size (pages) = 128
Prefetch size (pages) = 512
Number of containers = 4
Minimum recovery time = 2005-03-08-13.23.35.000000
