Hi,
1) If I need to monitor a resource eg, bufferpools at the database
level across all users, how can I do this ?
If snapshot monitoring needs to be done wouldn't enabling the switch
at the DBM level cause performance problems ?
2)How does one find the SQL statement that a particular user session
is executing?
TIA,

Hello,
I would like to get the logical and physical reads for every sql statement
executed.
Thatfore, I used the command "db2 get snapshot for dynamic sql on
<mydatabase>". There, I could see the logical and physical reads from
bufferpool for every statement monitored. Am I right?
But now, I would like to read these results out of a table so that I could
process them automatically. In which table(s) are the results of snapshot

Hi,
I can not understend completely the lock statement.
Actally what is locked:

Hi all
I'm using DB2 UDB v8.2 on linux.
After minimizing the code in order to isolate the problem, I have a
simple jdbc client that executes the following SQL statement in loop :
SELECT * FROM TABLE (SNAPSHOT_LOCK (CAST (NULL AS CHAR), -1)) AS
LOCK_INFO
After each query the client sleeps for 100 ms, and then continues the
loop, so the database machine is not under load (cpu consumption is

I have a query that returns different results (3508 rows for snapshot,
6288 for dynaset) and that is the only thing I change to get the
different results. When I try to make a table from the query, it
makes 3508 rows. I also know that there are 6288 unique rows in the
results. Is there some configuration choice that is causing the
snapshot version to return the wrong row count?
Thanks for your help on this one. If it wasn't that the...
