Hello Everyone
We have a third party tool which maintains its own custom
database,DB1 on SQL Server 2000 on Server A (Windows 2000). We built an
inhouse application which maintains a transactional database, DB2 also
on Server A derived from DB1. Since the DB1 is frequently updated the
synchronisation between the databases is currently maintained by using
views in DB2 which pulls in all the required data from across tables in
DB1.
But we found that the cost of employing views, referencing tables
across databases has made the inhouse application slower and so as a
apparent performance tuning measure we plan to maintain a subset of
data(for a specific time period) from DB1 in actual tables with same
schema in our transactional database DB2. But since the tables in DB1
are frequently updated during the day we are required to the
synchronise the corresponding tables in DB2 with their counterparts in
DB1. The only constraint in this synchronization being that the third
party custom database,DB1 cannot not be subjected to any changes (like
creation of triggers) as it is maintained by a different group of
personnel.
I read about Triggers,Mainte nance Jobs and Replication but not sure
which would suffice our needs.Are there any recommendations on how this
could be carried out? Any suggestion would be welcome.
Thanks

Hm, wonder if transactional replication can be used here? Normally, when
you replicate a table, you replicate it all. Here you only want some
data to be replicated. But you should be able to set up filter for this,
I believe.
Anyway, I'm not very good at replication myself, I would encourage you to
pursue this in microsoft.publi c.sqlserver.rep lication.

I have a question regarding synchronization across multiple threads for a
Hashtable. Currently I have a Threadpool that is creating worker threads
based on requests to read/write to a hashtable. One function of the
Hashtable is to iterate through its keys, which apparently is inherently not
thread-safe. Other functions of the Hashtable include
adding/modifying/deleting.
To solve the synchronization issues I am doing two things:

Our product uses MS-SQL Server 2000. One of our customer has 10
installations with each installation stroring data in its own database.
Now the customer wants to consolidate these databases into one and we
already have plan for that by consolidating one DB at a time. But first
they want to find how many unique or duplicate entries they have across
all the 10 databases

Say you need to serve the same Web content from a number of IP
address, which you need to keep out there with high availability
requirements

I think Web Services would be a good candidate for the
synchronization of Web pages/content.

What some frameworks do is database development and then let the
databases themselves do the synchronization (Should I update my
knowledge of this subject ;-))

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...
