dms with stripe type volume

hi, i would like to choose dms type tablespace for the user data , the
server is db2 udb v8.1 on windows 64 bit, the volume created is use
stripe type, so it will cross the data on two different disk with same
logical volume , is this help for performance, will this cause problem
if we need to restore in different server without multiple disk ?

Striping is always done at a lower level than db2 uses to access harddisk.
So I would expect no peoblems.
It is "help for performance"!

Make sure you extent size is an even multiple of your strip size. Remember
that extents are the number of pages and the stripe size is usually
expressed in K bytes.

You can not stripe the disks via the OS, and just let DB2 stripe the
tablespace by placing one container on each disk. This may actually work
better, especially if you have 2 or more processors.

I was wondering if anyone has heard of problems with the Export utility writing dump files on stripe-sets. I'm not sure if the stripe-set is configured correctly or not, but everytime I place my dump file on this set, I can't import it. I always get errors/crashes. I appreciate your help. Cheers. Kevin

I'm trying to put a vertical blue stripe with a black border on this page that will remain colored even if the page is scrolled in the UA. http://maba.org/new/homeproducts/ As you can see, the stripe is there, but Gecko only draws it for the initial viewport and chops it off if one scrolls down. MSIE stops drawing the background color at the end of the last link on the left side. I've messed around with the stylesheet to no end, and...

Hi, I have some questions related to stripe sets that I'm hoping someone here can answer. 1) What happens to stripe sets when doing a database restore? Do they stay as is? 2) What happens to stripe sets when doing a redirect database restore? Will a new tablespace map be created by this and thus override the existing

Hi folks, I've tried reading just about every post I can on raid stiping / extent size etc and I'm just getting myself more confused than ever. Here's my situation. On a Windows Server 2000 standard edition system with only 1gb ram using UDB 8.2.3 Enterprise, I have an existing database that uses two raid arrays striped with 8kb. Presently the tablespaces have a default extent of 24, default prefetch of 48 .

I'm trying to access my database of records via a mag stripe reader. I've created a querry that prompts me to enter a number. I thought that I might just swipe the mag stripe and the appropriate record would come up. No luck. Do I need to purchase software to do this?

I have a wedge mag stripe reader that I swipe when ask to input information in a query. How do I filter the unwanted characters. Apparently there are two mag stripes that are read every time I swipe the card. The first line has the name information and the second line has the number that I want to use. The number looks like this when I swipe a card. %00123478? I need to filter out the % and the ?

I've ordered a mag stripe reader for Driver's Licenses but I want to get a jump on raw data parsing. I have the stdAAMVADLIDCardSpecs_092003.pdf which defines the structure of the raw data, but I would like to double check before I start writing parsing routines. Does anyone have raw AAMVA data? The data doesn't have to be real but the structure has to be correct. Thanks

I have an OLTP database that has a tablespace that will start out at about 1 TB, but may grow to 75 TB's in size over the next 5 years. When I add new containers (on a new mount point), I want to use the BEGIN NEW STRIPE SET command to avoid rebalancing. Anyone know the maximum number of STRIPE SET's that can be created for a tablespace.

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,...
