Dropping indexes on a partitioned table

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??

If you're talking about range-partitioned tables, DB2 only has global

If you detach a partition into a table, that table will *not* have the
indexes defined on the partitioned table.

So you could detach the partition, load the data, and then reattach the

Dear oracle gurus, I have created a non partitioned table with no indexes and stuffed in about 15 million rows. Using oracle 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,

I'm confused about something I did this week. I have an database with tables partitioned by dates. I recently dropped my maxvalue tablespace, added a few more partitions for up-coming dates, then put the maxval partition back on. (I save the data that was in the maxval partition first and put it back in when I was done. These tables also contains BLOBS. All of my indexes were at a status of either "Valid" or "Usable" in the case of...

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 have an archival process on a large database that runs once a month. At the beginning of the process the triggers and indexes on the tables whose data is moved are dropped, the data is moved and then the triggers and indexes are recreated at the end. This produces a massive improvement in performance. The problem is the process is supposed to run on users accounts (thats the way the front-end is set up) and they don't have the...

I have a partitioned view sitting over several tables and I'm slowly approaching the 256 number. Can anybody confirm if there is such a limit for the maximum number of tables that a partitioned view can hold? If this is true, does anybody have any suggestions or ideas to work around this max limit? TIA!

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.

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...

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...
