I'm sure this is a concept that's been explored here. I have a table
(fairly simple, just two columns, one of which is a 32-digit checksum)
with several million rows (currently, about 7 million). About a million
times a day we do
select * from my_table where md5 = ?
to verify presence or absence of the row, and base further processing on
that information.

DB2 V8.2 (not Viper yet and no range partitioning!!)
I have created a table T1 (col1, col2) with col1 as the primary key.
When I try to create a partitioning key on col2, it gives me error that it
should have all primary keys included.
So, I created table T1 again with col2 as the partitioning key.
Now, I do not have col1 as the primary key.
When I try to create col1 as the primary key, I get the following error:

--Decalre variables
DECLARE @LastFilegroupName VARCHAR(50)
DECLARE @FilegroupName VARCHAR(50)
--Retuns the next FileGroup to be used

Does anyone know of any documentation on the performance of partition
merge/split? Does the merge or split of a partition cause any locking
on the partitioned table? If you were merging or splitting a large
volume of data rebalancing your partitioned table would you
potentially lock users out?

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
