Hello,

Setup: 9.7.1 (64 bit) running on x86_64 Red Hat Enterprise Linux 5.4.

Often, when I take look at the list of applications, I see a session with
application name "db2lused" in a state of "UOW Executing". Example:
http://troels.arvin.dk/db/db2/db2lused/db2lused.txt

Google is rather silent about db2lused. Only hit is at ftp://
public.dhe.ibm.com/ps/products/db2/info/vr97/pdf/en_US/
DB2PerfTuneTroubleshoot-db2d3e971.pdf which states:
db2lused, for updating object usage

The application doesn't seem to cause any harm (such as CPU or I/O
usage), but I find it strage that it's running so often and for so long.
Should I be worried? Is it an expected scenario?

This updates the last used status for tables and indexes. When a table/
indexe is used, the lastused column in the syscat.tables/
syscat.indexes is updated with the time when the table/index is used
for the last time. In that way, you can identify the indexes/tables
which are not used for long time and drop them to reclaim the space.

Hello,

Thanks; that makes sense. But it makes less sense that the db2lused
session seems to be running in Executing mode long after the user has
stopped performing activity in the database.
