Hi,
Currently we're a building a metadatadriven datawarehouse in SQL
Server 2000. We're investigating the possibility of the updating
tables with enormeous number of updates and insert and the use of
checkpoints (for simple recovery and Backup Log for full recovery).
On several website people speak about full transaction log and the
pace of growing can't keep up with the update. Therefore we want to
create a script which flushes the...

I understand the concept of catalog cache (memory allocated from the
dbheap to allow catalog lookups without the need to access disk each
time). But the DB2 catalog tablespace (SYSCATSPACE) is assigned a
buffer pool, which seems to perform the same function as catalog
cache.
Is this simply a case of double buffering? Can anyone clear this up?

I have a table which saves doctors' notes about patients. The format
of the material is rich text format +/- embedded graphic(s) (.bmp,
..gif, .tif, .jpg, etc).
The size of a note is unpredictable: maybe 4k, maybe 100k. Majority
under 32k. Figure five under 32k for one over.
At this moment all rows saved as BLOBs.
Would I be better off to redo this as two tables: one for VARCHAR(32K)

Just wondering if/how a sliding Cache expiration interacts with Application
Pool Worker Process Recycling.
Specifically, if I were to place some value into the Cache object with a
sliding window of 2 hours, but
property setting for the relevant App Pool is 1 hour (and there is no
activity following the placement of the data into the Cache), then WILL the
data automatically be removed from the Cache when the App Pool recycles? Or,
is it...

I have a very basic question on the two parameters shared buffers and
effective cache size. I have read articles on what each is about etc. But I
still think I don't quite grasp what these settings mean (especially in
relation to each other). Since these two settings seem crucial for
performance can somebody explain to me the relationship/difference between
these two settings and how they deal with shared memory.
Thanks much
Sally

Just started investigating InnoDB after having used MyISAM tables in
the 4.0.12 version, almost immediately ran into a locking issue with
INSERTs, DELETEs, and transactions.
Given the following table:
CREATE TABLE test1 (
f1 varchar(32) default NULL
)
and a steady stream of INSERTs from a command-line shell:

Hi,
I've read everything I can get my hands on and am still very
confused about the similarities and differences between
db2_mmap_read/write and concurrent i/o. It seems to me at this point
that they are virtually identical except that db2_mmap_read/write
applies at an instance level and concurrent i/o can be aplied at a
tablespace level. It seems that they both bypass the AIX file cache
and eliminate i-node locking. Is this correct?

Is there a way in Javascript, or perhaps in HTML, to force a browser to
re-render an image on an HTML page after a round-trip between the client
and the server ?
In my particular case, the image is changing on the server although the
URL for it remains the same, but the browser is still displaying the old
image from its cache rather than the new image from its URL location.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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...
