Do you think that these indices (in the following definition) are performance-based?

CREATE TABLE current_inventory
( warehouse_id NUMBER
, warehouse_region VARCHAR2(2)
, product_id NUMBER
, product_category VARCHAR2(12)
, amount_in_stock NUMBER
, unit_of_shipping VARCHAR2(20)
, products_per_unit NUMBER
, last_updated DATE
) PARTITION BY LIST (warehouse_region)
SUBPARTITION BY LIST (product_category)
SUBPARTITION TEMPLATE
( SUBPARTITION perishable VALUES ('DAIRY','PRODUCE','MEAT','BREAD')
, SUBPARTITION non_perishable VALUES ('CANNED','PACKAGED')
, SUBPARTITION durable VALUES ('TOYS','KITCHENWARE')
)
( PARTITION p_northwest VALUES ('OR', 'WA')
, PARTITION p_southwest VALUES ('AZ', 'UT', 'NM')
, PARTITION p_northeast VALUES ('NY', 'VM', 'NJ')
, PARTITION p_southeast VALUES ('FL', 'GA')
, PARTITION p_northcentral VALUES ('SD', 'WI')
, PARTITION p_southcentral VALUES ('OK', 'TX')
);
CREATE INDEX warehouse_id_ix ON current_inventory(warehouse_id)
LOCAL PARALLEL NOLOGGING;
CREATE INDEX product_id_ix ON current_inventory(product_id)
LOCAL PARALLEL NOLOGGING;

It depends on the type of your request.
If the application is OLTP, I think that these indices are not good performance because these indices are not pre-fixed clues. Indices non prefixed are not suitable for OLTP.
If your application is DSS, these indices are appropriate.

I love the develop module, but I'm doing something wrong in the library
In the library, under 'Catalogue, all the photographs', all my photos appear showing the stars, cropping, and development. The problem is that these changes are not for the photos on my hard drive. When I re-import them in Lr, the changes are not there. My workflow is to do nothing after development or export them to the original with a new file name destination. Anyway, it is that they get a new file name without change of development when they are imported into Lr. Please help (PC user)

And others have explained, Lightroom does not apply the changes to the file. All changes are stored in the catalog, and then applied to the image when it is displayed in Lightroom. If you want a copy of the image with any changes so that you can share with others or send it to a laboratory to print, then you must export a copy of this image by using the export dialog box in Lightroom.

Features of Lightroom as well by its design. The images that you import are always left in their original condition, unmodified.

If you're both using Muse, then it is no different that is both using PS, you HAVE, Word, etc. You must use a mechanism that allows all both have access to the most recent version of the .muse file (i.e. the creative Cloud Files, Dropbox, file server location folder, etc.).

Changes made in the browser will be able to be synced to the .muse file. Changes in Muse are saved in the .muse file and if you go to work on the site of Muse on two different machines then you must have the updated on the other machine .muse file.

What do you think of these tips guys

Hi I've recently asked a Scott Moulton at http://myharddrivedied.com/

If checkdisk scan would be performed/damaged one of my videos, that's what he said,

I wish that microsoft had never put these tools into the system, there is no

destroy data. Yes, the current process only destroyed data or affect
files. And the process is irreversible.

ScanDisk collects clusters that are damaged based on some very
simple process where it checks two bytes in the MFT entries and then if
those who are not correct it will assume the data is corrupted and the block
will be badly marked and a cluster or file will disappear.

I'm in disagreement then he answered me.

You're wrong, Microsofts tool does not repair it removes and destroys clusters. Yes, it would affect video.

Is it possible checkdisk would destroy my videos, it's a hard drive again and very little used, checkdisk said he needs to fix file system errors, but I have'nt checked to do it again.

My videos be feasible, if there is no microsoft here one can you tell me if the checkdisk can do what he says?, or only if the hard disk is damaged without repair possible.

Hi, RobertGeek,

You are right to disagree

CHKDSK is designed to find and fix errors on the hard drive. He is looking at the file system NTFS or Fat32

This isn't a question, but I think that these things should be done for iOS 10.

I watched a few videos on iOS 10 and what we should be waiting, and I think that this video captures 10 of the most important things that should be added in iOS 10 just to make life easier and more customizable.

My Windows 10 computer crashed, and all applications have been lost. I'm about to re - install LR6 (standalone, no CC). I think that both facilities are allowed. Can I get the meter re - assign once my reinstalling? Thank you. Jim

Hello, my Windows 10 computer crashed, and I had to start again, allow a reinstallation of the operating system complete with all my apps being deleted from the machine. One of these applications was LR6 (independent, no CC). In my view, LR6 allows two installations of the software by license, so I am writing to ask that the 'meter' installation reset 'one' when I'm done with this installation. I would never need the re-install second, but given the instability of the operating system, it may be necessary... Thank you.

People probably think that my answers are boring

Whenever I reply to a thread after that who knows we're going on anymore. I see a bunch of sansafinders in the last section of response on this forum that goes back to a week ago. I guess that my eyesight has begun to make everyone bored of my messages. I don't think anyone will respond to this message in any case.

Look at it this way... you have the "last word" on plenty of conversations or discussions.

Oh and good luck delete this thread... you can delete a message if no one responded to it. Only the Admin & Mod have privilege ths. And a good thing too; people would be deleting stuff in every sense, if they could.

Photos only displays videos to 2013 when there are videos iOS clear in 2010. When I try to re - import videos from my iMac, hard drive, I get a message saying that these videos are already imported, but I can't see them.

I don't know what it is but Photos only shows videos of courses on April 22, 2013. I have iOS videos of 2010 on my hard drive on my iMac, but cannot see them in the pictures. When I try re - import the photos in the hard drive gives me a message saying that they are already imported but asks if I would like to import again. If I import them once again, I can see them under import last but still do not see in all the pictures or videos. It is across all devices. I cannot see them on iMac Photos program, cannot see them on iCloud.com in pictures, can not see them in the pictures on any iPad (mini (3rd generation) or Air 2) or iPhone 6s.

Any help would be great.

How do you think that all comments in a document to the list on the right (or anywhere for that matter) rail as in the old Adobe?

A large part of my job works with PDF files that have a lot of comments, sometimes hundreds. I can't even remotely effectively without the option of a list view clean and convenient to use to scroll. I'm sure there must be a way to do this in the new Adobe, but of course I can't find. I must say that the old Adobe had its bugs, but I am appalled to see Adobe as a result of this trend more and more enigmatic UX. It's 2015. You really, really easy to make something users can intuitively understand and then test to make sure that it is, in fact, intuitive for real users who aren't 23 years working in technology companies. Yet I sit here spending 45 minutes trying to figure out how to see a list of stupid comment! Come on, guys, do your tools for the love of the crisp.
