How can we use the table partitions feature and.........

Hai friends when i tried to use the bitmap indexes and table partitions feature ,
I got a message like this
'table partiotion feature not enabled'
so please tell me how can i enable those features so that i will be able to use those features..........

Partitioning and Bitmap Indexes are features of Oracle Enterprise addition. In fact, I think that Partitioning is an extra option that needs to purchased with Oracle Enterprise - it is not a default feature.
These features do not exist on Oracle Standard Edition (and likely Express Edition too).

JPA - How can I use the table's default Date types? e.g. CURRENT_TIME

Once again, can't find an answer anwhere.
I would like to know if/how one can use the default date/time/datetime types as declared for the target table when attempting to persist an entity having these fields set as null.
create table item
     item_id INTEGER NOT NULL PRIMARY KEY DEFAULT AUTOINCREMENT,
     date_created DATETIME NOT NULL DEFAULT NOW(*),
     date_updated DATETIME NOT NULL DEFAULT NOW(*),
);Now how can I get the above table to work when attempting to em.persist(myItem) whereby dateCreated and dateUpdated are both null?

I should also mention that TopLink has always supported the ability to retrieve the current time from the database for use in optimistic locking. The TimestampLockingPolicy offers the ability to configure the next value being retrieved from the database instead of using the local time from the JVM. Our extended optimistic locking configuration does not currently support setting this option but it could be done using a descriptor customizer which can be configured in your persistence unit properties.
Using optimistic locking may be a good solution for the last modified date since it will also ensure that you do not corrupt the database if someone else has incremented this value since your last read.

How can I use the hardware compare feature of the 6551 card to trigger scripts

I can dynamically and seamlessly generate different waveforms by triggering different scriptTriggers that drive one or more of the 4 PFI lines. However, I need to evaluate a channel at a specific location or locations set by a script marker in real-time and generate a different waveform stored in on-board memory based on the result of the evaluation. I have attempted to use the hardware compare feature without any success. I am trying to dynamically respond to an I2C device based on the ACKs or NACK response of the device under test. Can the 6551 card accomplish this? Has anyone successfully tested an I2C or SMBus communication stream with 6551 card?

Hello,
I can understand why hardware compare did not work out for you application. Hardware compare uses a signal that was generated to make a digital pattern and then waits a few clock cycles before acquiring the signal that needs to be compared to the digital pattern.
I would look into using a script trigger to evaluate the channel value, where the script structure controls when it is evaluated. Please note that script triggers will need to be cleared after they are detected for reasserting. Some script syntax actually clear the script trigger and then use a wait until script trigger structure. Please refer to the HS DIO Help for documentation on Common Scripting Use Cases.
Please provide us with further details about your application. The more information, the better! I was not too clear on what you where wanting to evaluate and where is it coming from.
I would also like to mention that National Instruments has a NI USB 8451 which is capable of I2C communication.

How can I use the "create book" feature without having my album photo sequence altered

I have created an album with photos that are in a particular order for a reason. I then process to create a book. The template then rearranges all my photos. Is there a way to keep them in the original order I set up?

All the 5000 photos that reappeared after repair today were from my canada mega event, but for some reason it did not do it for all the other mega events. It is a start but not complete.
Try the rebuild to recover more lost photos.
If "rebuild" with iPhoto does not recover more lost photos, rebuild with iPhoto Library Manager as described by Old Toad in this thread, but rebuilding with iPhoto Library manager will not recover your projects like cards, bilks, slideshows.
Re: iPhoto glitch with retained masters https://discussions.apple.com/message/26354337#26354337
Mostly the way I organize all my photos is that I make a folder for each country I visit. i.e. New Zealand Folder, Canada Folder, India Folder; and at the same time, any photos that I import I delete directly from new imports and just keep the ones i want and then i go up to events and move the latest imported event into a mega event for that country and so they all get joined in a sense.
As a workaround, merge the events right after importing, before you start deleting photos. And empty the trash always before merging projects.
You might consider to use albums instead of events for your country lists. I simply use the events as basic containers. One event for each day of shooting photos. I found, that smart albums and searches are quicker in iPhoto and Aperture, if the events are smaller, also browsing is easier, if the events are not so large.
You can merge albums and remove photos from albums without the problems mentioned above.

I have 2 iphones in the family and want to use itunes match on both devices, but my husband has his own itunes acct, how can he use the main itunes library and get out music on his phone also

I have 2 iphones in the family and want to use itunes match on both devices, unfortunately my husband has his own itunes acct and when i change on his phone to my itunes acct it states that the email is already in use, any help on how to get the itunes match to go onto both devices, thanks

"Method Three
Create a separate iTunes library for each device. Note:It is important that you make a new iTunes Library file. Do not justmake a copy of your existing iTunes Library file. If iTunes is open,quit it.
This one may work. I searched and searched on the website for something like this, I guess I just didn't search correctly, lol. I will give this a try later. My daughter is not be back for a few weekends, therefore I will have to try the Method 3 when she comes back for the weekend again. "
I forgot to mention that she has a PC at her house that she also syncs to. Would this cause a problem. I am already getting that pop up saying that the iPod is synced to another library (even though she is signed in with her Apple ID to iTunes) and gives the pop up to Cancel, Erase & Sync, or Transfer Purchases. My question arose because she clicked on "Erase & Sync" by mistake when she plugged the iPod to her PC the first time. When the iPod was purchased and setup, it was synced to my PC first. When she went home, she hooked it up to her PC and then she erased it by accident. I was able to restore all the missing stuff yesterday using my PC. However, even after doing that it still told me the next time I hooked it up last night that the iPod was currently synced with a different library. Hopefully, you can help me understand all this. She wants to sync her iPod and also backup her iPod at both places. Both PCs have been authorised. Thanks

How can I use the same sleepimage over and over?

Hi, this was asked a while ago for Tiger, but had no real answer. Now I hope things have changed in Leopard 10.5.4.
I have a STATIC system on a car that should boot over and over in exactly the same way. The idea is to make a good sleepimage (/var/vm/sleepimage) and then force the computer to read it at every startup AS IF it was waking up from sleep mode all the times.
This MUST be possible because OSX does it every time it wakes up from safesleep (sudo pmset hibernatemode 1). All I need it to find out WHERE OSX writes down that at the next wake it should use the sleepimage instead of a normal boot. Then, once I know where it write this, I simply force that flag to be active all the times.
Please also be aware of the following notes and constraints:
0. The boot should be as fast as possible
1. I can't to use the regular sleep function: the system must drain zero power while shut down
2. There are no dangers in using the same sleepimage multiple times: the disk contents do not change. The system should be absolutely identical at every boot (or "wake")
3. The system is ALWAYS shut down by pulling the plug of the MacMini. Thereshould be no possibility for the system to "update" the sleepimage
I hope some of you OSX experts will give me a hint concerning where this information is stored (and maybe how to override it)
thanks a lot

I am not positive what you did is going to work, but it seems like you did the equivalent of imaging a small disk on a bigger disk. In that case, the first thing to do is update the partition table with fdisk. Start with fdisk -l in the vm for general information about the disk. Hopefully, the additional space will show. Then, work with fdisk to use the extra space. The easiest is to add a partition, then a file system on it. It is also possible to expand the last partition (you might have to delete it first), then expand what is on it (may be RAID, LVM, or the file system), layer by layer. As usual with fdisk, you run the risk of thrashing it all, so you may want to practice on a copy first. Obviously, the extra space can only be added to the last partition of the small disk.
If the situation is more complex, you may have to boot a VM with both the small disk and the big disk at the same time. If you boot the VM off of an iso DVD image, you can then shell out, then run fdisk to partition the big disk the way you want, then use dd to copy the partitions you want in the order you want from the small disk. I am pretty sure not all combinations will work, but you get the idea. You can then take the small disk out, and boot off of the big disk.
Come to think of it, you might just be better off with adding more space as a second virtual disk. You would then be free to partition/format it the way you want without messing with the first disk. Linux is so good with disk management, so many options.
As a general statement, though, I like to put some distance between the high level file systems and the low level disk partitions, so I use LVM (Logical Volume Manager).
Best of luck, keep us posted.

How can I use the print module to print different size images on one large "canvas"?

How can I use the print module to print different size images on one large "canvas"? An example would be in Photoshop, go to file>new, and create the size paper I want, and move images of different sizes onto it.
I was thinking the print module would do this automatically for me.

You can't, at present. It's been a requested feature, so we'll see if it shows up in a future version, but it's not there at present.

HT3354 how can i use one table for reference to another

how can i use a table for a referance to another eg when i type a word in a cell, i will like it to match the word with another table then return the information in the cell i am using

you can use vlookup() (or any of the lookup family of functions) to locate an item based on a key value:
Here is an example of something you can do with two tables:
The table on the right is title "Data" and stores a list of names with age and favorite color.
The table on the left uses the value in the first column to lookup up information in the table Data
in the table on the left:
B2=IFERROR(A2&" is " & VLOOKUP(A2, Data :: A:D, 2, 0)&" years old and likes the color "& VLOOKUP(A2, Data :: A:D, 3, 0), "NOT FOUND")
I know this look complicated. so I'll break it up into smalled pieces:
first the "&" is called the concatenate operator and joins two strings. like this:
a string is a set of characters between double quotes.
so "string 1" & "string 2" becomes "string 1string2" or "Sam " & "Jones" becomes "Sam Jones"
you can use cell references instead of strings directly in which case the concatenation is performed on the contents of the cells.
so if cell A1 contains "Hi " and the cell A2 contains "There" then A1 & A2 will result in "Hi There"
so you could add the formula
A3=A1 & A2
this is short hand for select cell A3 then type everything including the A3 so that A3 contains "=A1 & A2" (omit the double quote)
OK. So the formula I provided concatenates several items together:
it concatenates A2, then the string " is " then a formula, then the string " years old and likes the color " then a formula
the two formulas (highlighted in blue) perform a lookup of the value in cell A2 in columns A thru D of the table named "Data". If if finds the value in cell A2 in the first column of the lookup range in the table Data (column A) then it returns the value from the same row but in the second or third column.
all that is in a function calld iserror() to trap the condition where the calue you enter in A2 does not exist in the table Data:

How can I use the button in one panel to control the other panel's appearing and disappearing?

How can I use the button in one panel to control the other panel's

You want to use a combination of three features, a button on the panel,
code to notice value changes using either polling in a state machine of
some sort or an event structure, and a VI Server property node to set
the Visible property of the VI being opened and closed.
The button exists on the controlling panel. The code to notice value
changes is probably on the controlling panel's diagram, and this diagram
sets the Visible property node of a VI class property node to FALSE or
TRUE to show or
hide the panel. To get the VI reference to wire to the
property node, you probably want to use the Open VI Reference node with
the VI name.

How can I remove the BootCamp partition? as the size i created ws too small to install MS Office on 64Bit Windows 8.1 on MacBook Pro (Aug'13)

How can I remove the BootCamp partition drive for Windows 8.1, as the size which I created was too small for me to install Microsoft Office onto Windows 8.1 64-BIt. The machine which I have is the MacBook Pro 13' inch purchased in August 2013.

Either use Paragon's CampTuneX to resize it or use Boot Camp Assistant to remove the partition and restore the drive to one partition. Then create a new, larger Boot Camp partition. This will remove/delete/erase your Windows system.
