Can i use the char (defined as line iteam dim) in Aggregates

Hi
I am maintaining aggregates on cube. can i use char which is defined as line iteam dimenstion.if i use how will be the effect.
thanks
Shaliny

Hi,
of course you can use it!
The behaviour is the same than with the other characteristics: you will have as many records as DISTINCT ocurrences of the combination of all CHARS you have included in your aggregate.
I suggest to first create your aggregate with a fixed value on another characteristic so you can have a feeling about how many records it will have and how long it will take to create it.
In general if you have flagged your char in a line itm DIM it means that this CHAR has very high cardinality (nearly the same number of records than the fact table itself) therefore it wouldn't make sense to include it in a ggregate except if your filter it for particluar fixed value.
The only difference you have with this line itm DIM is that there is no DIM table as such; the chars is accessed firectly from the cube fact(s) table. This will be the same for your aggregate (no aggr dim table created, access form your aggr fact(s) tables).
hoping this help...
Olivier.

Can I use the Command Line Interface on Unix?

Hi,
We use 9iAS on Unix. We want to use Discoverer Command Line Interface on unix to export the worksheet query result. Can anyone know how to do this? I couldn't find out the command similar to dis5usr.exe for windows version.
Thanks.
Richard Qiu

Hello Richard
You can use the Discoverer EUL Command Line for Java utility. This was released with Discoverer 10g (9.0.4).
Please refer to the documentation for more information on how to use this command line interface: 'Oracle Discoverer EUL Command Line for Java User's Guide 10g (9.0.4), Part No. B10274_01 (PDF)' The document is available from OTN at http://otn.oracle.com/documentation/discoverer.html

Can I use the pdf fax with a DSL line

Can I use the pdf fax with a DSL line and, if so, how do I get the pdf fax modem to appear in my printer options? No Modems appear in my Modem pop-up menu.
Thanks,

Should I be able to fax using the internal fax software if I set it up with the proper settings?
Yes, if it's not a purely Digital line, dial that FAX number on your Phone, does it answer with a screech?
Must I disconnect all my other lines in order to use this?
No, you shouldn't need to... do you have DSL Filters on all lines except the DSL connection, like these...
http://www.twacomm.com/info/DSL_Filters.htm
Oh, it's not clear, do you have 2 actual Lines/Phone numbers, or do they share the same line?

I can no longer back-delete or hit return to make a new paragraph, nor can i use the arrows to go backwards and forwards in a line; it's like the fn key is stuck; i've taken it off and cleaned it, and it looked clean.

Hi
You should ask your relative to physically take the iPhone to the store rather than shipping it because as diesel vdub has said:
"No Apple store will accept an iPhone shipped to them"
All you have to do is safely pack and ship your iPhone from the Philppines to your California-based relative.

How can we Restict the Char single value Variables with , , =

Hi Experts,
How can we Restict the Char value Variables with <, >, <= (without selecting Inverval or only passing single value)
For Example
We have a standard Query 0FIAR_C03_Q1005, in this
New Selection
"1 - 15 Days, Posting Date<=Key Date, Clearing Date>Key Date"
This is restricted with the
Clearing(0CLEAR_DATE)
<Clearing key date(0P_KEYD3) It is a single value SAP Exit Varible
PostingDate(0PSTNG_DATE)
<= Posting keydate(0P_KEYD3) It is a single value SAP Exit Varible
When seeing these 0P_KEYD3, 0P_KEYD3 variables in the New selection screen they looks like >0P_KEYD3, <=0PSTNG_DATE
if you define any custom variables these are looks like =ZV_DATE.
to enable < , >, <= symbols for variables what we need to do.
In other way
Say we created one variable ZV_DATE single value, processing type as customer exit.
for this we populated current day,
Now Requirement is we need to display the all the records which are <= current date,
instead of passing low and high values, i want to restrict the calday <=ZV_DATE
New selection
0calday
<=ZV_DATE
How can we achive this, this is how the business content report having the restrictions
Please sugget me.
Thanks
Chandra

Ok,
In the InfoObject 0calday in the query designer under the filter area, under characteristic restrictions right-click over that InfoObject (0calday).
In the next window (select Values for [0CALDAY] Calendar Day in the dropdown box for "Show" choose Value Ranges. Under the word "Between" dropdown box select "Less than or equal to"
Below that word click on the button of the dropdown box Select from list.
In the new window select instead of History Variables and double-click on your variable ZV_DATE.
Click on the right blue arrow to move it to the right.
And there you go.
Tip: It exists a SAP standard variable named 0DAT which is exactly the current date (don't need to use ZV_DATE variable).

Apparently this UDF takes two optional parameters so that one
can define
(A) a text "qualifier" to use in the CSV file, this is
usually the
single quote|tick ['] mark - but sometimes one wants this to
be a
different character and (B) what columns to use in the
output in case
one does not want to use all the columns in the record set
in the
outputted CSV file.
The if statements are checking for these optional parameters
and if
found setting the values in them to internal variables.
These
variables are then used in the rest of the logic to create
the CSV output.

I'm in the trial period for Creative Cloud - I have about 19 days to go on Photoshop CC on my iMac. Can I use the same CC trial on a second machine? Specifically on a Windows 7 machine?

Nothing personal to you or Rajshee, but this is exactly why I absolutely despise these "community forums" (not just Adobe but any company). I called the Tech Support phone line today after digging and digging for a phone number, and they told me the exact opposite, and they did it a lot faster than it was possible to get a forum response. (That's really not personal, because you can't control that, but it's a fact.)
Their answer: As long as I'm signed in with the same ID, I can try, say, Photoshop CC on my iMac at home and also try Acrobat Pro CC on my Windows 7 machine at work. Same account, same login, one trial.
This makes complete sense to me as I'm financially on the hook (potentially) for the same package. If I give away my login to someone else, which I wouldn't do, I'm still on the hook. This is why the cloud approach to software is such genius and I applaud it.
BTW, 99% of the "community forum" wrong answers come on Microsoft sites, so don't feel bad.

How can I use the pulse train from a 6602 to trigger an niFGEN and niSCOPE on each rising edge of the pulse train?

Hello,
Here is my application: I need to use a 6602 counter/timer to generate a pulse train of certain frequency and duty cycle. On each rising edge of this pulse train, I need to output an arbitrary waveform on Ch. 0 of an niFGEN (5422) AND acquire data from CH. 0 of an niSCOPE (5124). I also need to synchronize the niFGEN and the niSCOPE to the same clock used for the pulse train (6602/ctr0). This process needs to continue until the user stops the system.
I can generate the pulse train using the 6602 just fine using ctr0, but the pulse train shows up on OUT0 by default. When setting up the niFGEN and niSCOPE to trigger on rising/positive slope edge, OUT0 is not an option for either device as a source for the digital rising edge (pulse train). The main options for both are PFI0-3 and RTSI lines.
Questions:
1.) Is there a way that I can direct the pulse train to a location (such as an RTSI line) where BOTH the niFGEN and the niSCOPE can use it as a start trigger for each rising edge? I noticed in MAX that a route can be made between ctr0's internal output and a trigger line and others. If this is a solution, could you please explain how to accomplish this?
2.) Once I configure the niFGEN and niSCOPE to be triggered on a digital rising edge, how can I effectively have this happen for every rising edge from the pulse train? In other words, can I just initiate the FGEN outside of the while loop and it will generate a waveform for each rising edge it sees at the source until the while loop is exitted?
3.) Is setting a reference clock for the niFGEN and the niSCOPE the same thing as synchronizing both devices using the same clock that generated the pulse train? It is not clear to me the difference, and why it would necessarily be useful.
Images of my current front panel and block diagram are attached. If you would rather have the actual VI's just let me know. Any help and/or explanation on this is greatly appreciated. Thanks in advance.

Hello Cgifford,
Welcome to National Instruments Forums.
To output your signal to the PFI lines,
you can use external connectios between OUT0 and PFI lines. You can also use
the backplane to do so by routing into the same RTSI line.
1)
On the SCOPE and FGEN, the name of the
terminals are actually “PXI Trigger Line x/RTSIx” but on the 6602 you might
need to route the signal using the property:
You can also use the DAQmx route signal which perform the same opperation.
2)
This will depend on the frequency of
your pulse train. If this is lower than about 10 ms, then you can probably
place this on a loop and start and stop the acquisition every time. If the
frequency is higher than this, you will have to use:
- Scripting on the FGEN side (read more)
- MultiRecord Fetch (more information in the scope help file
section “Acquisition Functions Reading versus Fetching”).
3)
The short answer is yes. The longer one
might depend on how tight you need the synchronization to be (us, ns, ps). For
very tight synchronization, you should look into here.

Can I use the same taskflow in the same page ?

I have an ADF library which I want to input into a single page (jspx).
In the single page, i drag a taskflow-A twice into showdetailitem1 and showdetailitem2. I used required parameter so I able to define each taskflow.
Everything looks good for the first time, and no error so far, but some component like carousel and af:foreach only works for the one of these regions.
My question is,
- can I use the same taskflow in the same page (2 regions) ?
- if yes, did I have to configure something to achieve this ?
Thanks
Riendy

Hi
Iterating over af:region will not work. Instead, try if using dynamic task flow id works—
<af:carousel ...>
<af:carouselItem ...>
<af:region value="#{binding.item1.regionModel}" ... />
</af:carouselItem>
<af:carouselItem ...>
<af:region value="#{binding.item2.regionModel}" ... />
</af:carouselItem>

</af:carousel>
In the page definition file, you should have the following—
<taskFlow id="item1" taskFlowId="#{backingBean.item[0].taskFlowId}" active="#{backingBean.item[0].active" .../>
<taskFlow id="item2" taskFlowId="#{backingBean.item[1].taskFlowId}" active="#{backingBean.item[1].active" .../>
So, you have a bunch of task flows ready to be displayed based on the what the backing bean returns.

Can I use the install disk on two computers?

I haven't actually installed it on my computer yet, I just allowed whatever was going to install itself to come up. If I have another computer, can I use the install disk to put OSX on there or not? If so, can I still use it in case I need a backup load of my computer?

Only if you get a family pack license newer than the installer disk which came with the computer(s) can you install it on multiple computers. Check your license agreement.
You can't use the disks which came with another computer on a second computer. These articles explain more along those lines:
http://docs.info.apple.com/article.html?artnum=25517
http://docs.info.apple.com/article.html?artnum=25784
As for backup, I recommend looking at these various procedures:

How can I use the Time Machine Backups from my Old Computer?

I have two months of Time Machine backups made using my old Macintosh computer which died and I no longer have. I have now purchased a new computer and am trying to use the Time Machine back ups from the original computer, but it will not recognise them. How can I get my new MacBook Pro to use the Time Machine Backups from my old Computer? I phoned the Apple help line and they said I cannot use them and would have to delete them. This sounds crazy if you can only use the Time Machine back up file with one computer and have to delete it when you buy a new Mac. Surely there must be some way to transfer ownership (not files) from an old to the new Mac?
Thanks
Richard

Thanks Kevin for the suggestion posted on MacOSXHints how to "Repair Time Machine after logic board changes".
http://www.macosxhints.com/article.php?story=20080128003716101
It seems as though I am not alone with my frustration with the way Time Machine uses the MAC address of a computer to tell one system from another. This means that if you have your Mac repaired with a new logic board, or replace your system with a new one, you can't resume backups where you left off. Reading through the readers who used the fix using Terminal, it appears that the fix does not always work. I contacted Apple again, but they were no help. Surely Apple should come out with a solution as more and more people use Time Machine/Time Capsule.
It is CRAZY that after a change computers or a switch in the computer logic board that you cannot resume your Time Machine back ups.

I have an airport extreme and express, if I use the extreme as a base station connected to my old router can I use the express to extend the signal while also creating a new network that only I can use?

I have an airport extreme and express, if I use the extreme as a base station connected to my old router can I use the express to extend the signal while also creating a new network that only I can use? Essentially having two wifi connection off the same network? If so how do I set this up?

Extending using a wireless connection always results in a performance compromise.
If the Express is going to extend using a wireless connection, then the Express will need to be located about half way between the AirPort Extreme and the general area where you need more wireless coverage. The more that you have line-of-sight between the Extreme and Express, the better the network will operate.
Remember......the Express can only "extend" the quality and signal speed that it receives, so it needs to be located where it can get a very good signal from the Extreme. Although Apple cleverly uses the term "extend", a more accurate term for the Express would be "repeater".
If the Express will extend by connecting to the Extreme using a permanent, wired Ethernet cable connection......highly recommended for best performance.....then the Express can be located exactly where you need more wireless coverage. There is no signal loss at all through the Ethernet cable, so the Express gets a full speed signal no matter where it might be located.
Post back to let us know which way to you want to go.

How can i use the airport time capsule as a external hard drive?

how can i use the airport time capsule as a external hard drive?

Why do you recommend not place things like iTunes libraries or photo libraries on the drive? It was what I am looking for...
I suggest that you ask the experts over in the iPhoto Support Community about their opinions on placing an iPhoto or Aperture library on the Time Capsule....even if you plan to use a wired connection for your Mac and the Time Capsule.
But, if Terrence Devlin answers, be prepared for a lecture about why you should not ever do this.
If you place the iTunes library on the Time Capsule, be prepared for iTunes to give you messages about not being able to find the library.
In addtion, LaPastenague has the answer for you in a nutshell......corruption problems.
Bottom line....the Time Capsule is for your backups.....not "everyday" files and especially not libraries.
