Partitioned table and its indexes

Hello all!
I created a range-partitioned table, and noticed that indexes were created
as "NOT PARTITIONED" (through db2look), even though I ran the index creating
commands without this parameter.
Not that I care too much now about it :-)
But what will happen when once upon a time in the future I execute the
"attach partition" command, and so add another partition to the existing
(partitioned) table.
Will the indexes then be automatically rebuilt, or do I have to do it myself
(perhaps by executing the "set integrity" command), or else...?

Another question: can I at all have a partitioned table where each table
partition has its own "index-partition", and does this make any sense at all
(why partition the index) and in what way (performance improvements, ...)?

Regards,
Damir

Dear oracle gurus, I have created a non partitioned table with no indexes and stuffed in about 15 million rows. Using oracle 8.1.7.4 standard. I then deleted 1 million and it took 1 solid hour. How can i reduce the time for deletes? Since oracle default locking behavior is row level locking, i changed to lock the table in exclusive mode before deleting. This dint help.. Any clues,

Hello, I have a large set of data that I have set up as a partitioned view. The view is partitioned by a datetime column and the individual tables each represent one month's worth of data. I need to keep at least two year's worth of data at all times, but after two years I can archive the data. A sample of the code used is below. It is simplified for space reasons. My question is, how do other people maintain the database in this type

I am using SQL Server 2000, SP3. I created an updatable partitioned view awhile ago and it has been running smoothly for some time. The partition is on a DATETIME column and it is partitioned by month. Each month a stored procedure is scheduled that creates the new month's table, and alters the view to include it. Again... working like a charm for quite some time. This past weekend I moved some of the first tables onto a new file...

I ran into a table that is used a lot. Well less than 100,000 records. Maybe not a lot of records but i believe this table is used often. The table has 26 fields, 9 indexes but no Primary Key at all! There are no table relationships defined in this database, no Natural keys, only Surrogate keys in the database. 1- Maybe an odd question but is it normal to have 1/3 of the table's fields as indexes? Is this a valid question or it really

Hi ... we're a mainframe V7 shop planning an imminent upgrade to V8. My application team is converting an IMS DB into a DB/2 table ... approximately 40GB of uncompressed (~20 GB compressed) data spread over 10 partitions. Approximately 35% of the data is "inactive" (easily identifiable as such) and of limited (but some) use. We require 2 non-partitioning indexes on the data. The DBA group would like us to put the "inactive" data into a...

The ETL application loaded around 3000 rows in 14 seconds in a Development database while it took 2 hours to load in a UAT database. UAT db is partitioned. Dev db is not partitioned. the application looks for existing rows in the table...if they already exist then it updates otherwise inserts them. The table is pretty large, around 6.5 million rows.

Indexes cause inserts/load to slow down. Is there anyway to drop indexes on one partition of a partioned table? From what I read this is not possible. I know Oracle has the option to disable local indexes. Is there anything similar in db2??

Hi All, Is it possible to create a partitioned index on a table which is not partitioned? If so what is such a partition called and please explain? I have done some research on partitions and index partitions and this is where I hit the wall the 2nd time. As per my study there are 3 types of indexed partitions: Global index (which is on an entire partitioned table) then there is Local Index (on just the partition of the table) and then there...

Overview: 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,...
