Any suggestion?
Thanks

Information Integrator can handle the replication, I think.
There are quite a few different approaches to this problem - if you're
using, or consider using an ETL tool then your vendor should hopefully
have a solution for changed data capture.
Otherwise, it isn't too difficult to do on your own.
If you need transaction-level detail, and really do need deletes: have
the application or triggers also write transactions to a change history
table, then extract from this (based on row timestamps > than last
extract)
If you only need snapshots, then the easiest solution can be a
'file-image delta': in which you export the table to a flat file, sort
it, and compare it to the last export. The output of this process is
typically a set of five files: new rows, deleted rows, same rows,
updated-new rows, and updated-old rows. Although I prefer to use a
utility that takes a config file for this, you could also run this
completely in db2. Instead of exporting, just copy data to another
table, then use queries in place of a utility. The nice thing about an
'image delta' process is that it's immune to inaccuracies caused by
non-logged changes to the tables.

I am a little confused by DB2 Backup and Export.
I used "db2 backup db QAS to /dev/rmt0" backuping 650GB database to a
IBM LTO 3581 (1 drive) only 11 hours. But I used "db2 export to
/dev/rmt0 of ixf messages MKPF.msg select * from mkpf" on the same
3581, and this table is only 5GB, but the export used 4 hours. What's
the diffirent between Backup and Export? I mean except backup is used
to backup whole database or tablespace, and export...

Good afternoon,
I have an asp.net project wherein I am trying to export data into
excel. I have that working, however, I am typically dealing with a
large volume of data when I do this. Can anyone suggest a better
method for this job other than reading the data into a datagrid and
then rendering the datagrid as an excel spreadsheet?
Any and all help is greatly appreciated.

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,...
