Is it possible to have FK tbl constraint to another schema?

Has anybody created successfully in OWB FK table constraints that point to a table in a different schema in the same instance?
Here is what I tried ...
Under table properties I created FK constraints that point to a table in another schema in the same instance. I used the drop-down list with locations under "Referenced Application" and then made column selections from drop-down lists below under "Local Columns" and "Referenced Columns". No problems with validation.
In the source schema I granted select and reference privileges. The generated code can be executed manually with no errors. However, I can't deploy a table like this. I get "VLD-0917: An unknown error occurred while generating ..."
Per tech support you can't have constraint references across nodes. However, I think this is somewhat different since it is all in the same instance.
Does anybody have any experience with this?
Thanks in advance,
Julian

Appears that after applying OWB patch 9.2.0.3 my problem went away. I created new schemas (design, runtime, target) after applying this patch also. Not sure what exactly fixed the problem in the end.
Thanks,
Julian

Constraints From another schema

Hi Guys,
I have a table referral_contacts which has a column customer_id.This col is coming from a synonym whose base table is in another schema.
So the current requirement is to establish the referential constratint from that table .I think there is no way to add constraint from a synonym whose base table is in another schema.Is there any method to achieve this without crating the same table .
Any suggestions,coments are highly appreciated.
Thanks,
Prafulla

Hi Prafulla
It will be very tough for maintenance in long term if you create cross-reference constraints across schemas. That won't be a good design unless the same application owns both schemas. If each schema is used by different application and that only the second schema is populated with data realtime which is needed by the other application then you can create a new table and refresh it from the other schema in real time as well. You can check Materialized views (fast refresh, incremental refresh, using rowid, etc) for this purpose or you can also look at various other options (using trigger on the second schema to populate the new table in your schema and keep this in sync with that).
Just for your information, Materialized views is a feature of EE. Tell us more about your environment

Is it possible to have one while loop in another while loop

Is it?

Well, actually there are several possibilities:
1. You right click the orange square where the double value gets out of the loop and select "enable indexing". This results in an array of all values you get while this inner loop is running.
2. You add a shift register to the outermost loop and use the "build array" function after the inner while loop. This results in an array of the last value after the inner while loop has stopped.
3. You combine both ways described above. Then you get a 2D-array.
You can see this in the attached vi. In every case you have to be aware of what happens with the memory. In case 2 and 3 the array grows steadily. This could leed to problems, so you have to take care to empty it, if possible.
Now it depends on what kind of data you need.

Adding named constraints from another schema using stored procedures

I need some help. I am trying to create a constraint like Primary key on a table in schema say 'a' from schema 'b'. in Oracle 10g. Schema b has all permissions of create, alter table, create index and other permissions required.
I can create this constraint from schema b using SQL command 'alter table add constraint...' but not from inside a procedure. I am using 'Execute Immediate' statement to alter table to add constraint. While trying from a procdure, it throws the error as 'insufficeint previleges'.
Kindly advise.

it is due to roles.
if schema b has for example role DBA it is not sufficient. You should
GRANT ALTER ANY TABLE TO B;maybe also CREATE ANY INDEX. not sure...

Constraints 18-840 - Differential pairs have different IOB constraint

Vivado 2014.4.
I have the following constraints in my design:
# Blanket statement
set_property IOB TRUE [all_inputs]
set_property IOB TRUE [all_outputs]
# Exceptions
set_property IOB FALSE [get_ports {I_MGTREFCLK0P_216 I_MGTREFCLK0N_216}]
The idea is, I give a blanket statement to prefer to pack IO into ILOGIC or OLOGIC, then I can give exceptions to avoid Critical Warnings if packing is not possible (because of design reasons).
After loading the Synthesized design (it is Synthesized outside of Vivado), I get this Critical Warning:
[Constraints 18-840] Port I_MGTREFCLK0P_216 and I_MGTREFCLK0N_216 are differential pairs. But they have different IOB constraint. Please correct the constraint value. ["constraints_file.xdc":52]
But when I run this Tcl command, it looks like I get the correct result:
get_property IOB [get_ports {I_MGTREFCLK0P_216 I_MGTREFCLK0N_216}]
FALSE FALSE
Why is this throwing a Critical Warning? It looks like it is working as expected.

If you want, you can bring down the message severity using this command in tcl_console:
set_msg_config –id {Constraints 18-840} –severity {CRITICAL WARNING} –new_severity INFO

Possible to Have ToC Default to Show Only Top Level (collapse sublevels)?

Howdy!
I'll bet I'm not the only one wishing for this. Let's say you're using Captivate 4's Table of Contents feature with a longish movie of Cp slides, which is chunked into bite-size sections content-wise. In the ToC, though, you can't mimic that same organization scheme; at least, the learner would first need to collapse all the ToC folders you've created so they see only the top-level listing.
This can be a critical issue: keeping the at-first-glance list in the ToC brief enough to be inviting to learners, yet allowing learners to drive which details are currently visible.
A movie's topical hierarchy could be along these lines, for example ...
Section 1 - National Brands
What are National Brands?
Why Are They Important to Our Business?
Working with Nat. Brands
Practice Your Knowledge
Section 2 - International Brands
What are International Brands?
Why Are They Important to Our Business?
Working with Intl. Brands
Practice Your Knowledge
You'd like to organize the ToC to show only the section titles (1st level) and to suppress the 2nd-level detail (slide titles) until the learner chooses to expand the folder to see those details.
I've tried things like grouping the slides into sections in the Storyboard view and organizing the slides into sections strictly within the ToC -- both to no avail.
Has anyone solved for this need yet?
I'm all ears, and you'd be doing learners of the world a huge favor.
Thanks!

Hi, Jim.
Thanks for being 'on the case' and looking into this so quickly. Your
findings are encouraging, although my user base is generally working with
IE 6 and FP8 or 9.
Since the only thing I may influence is getting IT to help push out FP10,
I'm hoping it's more of a player- than a browser-version issue.
I'll test things out by Monday and let you know the results. Wish me luck!
Dave

Dave,
I just tested this on my local web server and it worked fine. I created a
blank project with 8 slides. Created my TOC with grouping... 2 slides in
each group. I turned on self paced learning. I tried with and without the
widget and it picked up where I left off in either case. See
https://docs.google.com/leaf?id=0B86WuEq6SVwRNWIwMjhjODctMjE2Yy00MWE2LWI5YzEtMGQxYzNjOWQ0Z mI2&hl=en.
I published using FP10 and IE8 to view. Notice any difference between
your project and this one?
Thanks,

Is it possible to have an attachment within a pdf doc print at the same time the main doc prints?

Okay, so this may be kind of a weird question. We have some users who are wanting to add a page to an already existing xml document and correct me if I'm wrong, but I've read that it's not possible to add/delete pages from a pdf that's in xml format. Since that is not possible, I have added the page to the xml document as an attachment. Now what I am wanting to know is if it is possible to have the attachment print out at the same time as the main document. We are using the latest version of Adobe Reader and I have access to Adobe Acrobat Standard 9 & 10 and then I have access to Adobe Acrobat Pro 7. I've been unable to find anyting via google or by searching this forum so hopefully I'll draw out some kind of smart cookies and we'll get this figured out. I appreciate any and all input!
Thanks,

I know of no way to do this with Reader or XML.

Why cant I create a playlist for my music/song videos? Continuous play is also not possible in the video app on the phone!!!! previously, prior to IOS 6, it was possible to have both music videos & songs mixed in the same playlist in the music app

I am back with an update. I turned off Match on both the ipad and the iphone 5. By doing so I was able to sync my Iphone and ipad to itunes and store the music on my devices rather than the slow streaming. So far this has fixed my problems with the iphone I have all my music, playlist, most of the album art and so on. But the ipad is a different story. I have the music and artist but not one playlist I am sure Apple will have an upgrade soon that will address these issues they are usually very good about this.
Now have any of you experienced another problem that has existed as long as I have used faces in Aperture.
I have over 200 faces and they are organized a-z problem is I have this going on A-Z folowed by a few that start over A-Z followed by another few A-Z and again a 4th time A-Z. Imagine how difficult it is while I am showing someone the great features of my iphone, ipad and imac. Which I do talk highly of all the time. But how do I explain that even though their name starts with a or b or what ever they are not important enough to me to be in the first list of A-Z or even the 2nd or 3rd list of A-Z someohow they are in the 4th section of the list!!!!
I have managed to get the Imac to fix this but for some reason the IOS devices do not. Any ideas?
Thanks Al

Thanks in advance for any help!
You didn't specify whether you are using the "official" Yahoo mail app, or some other email application like K-9. But either of those allow for the specification of multiple email accounts, and you don't even really need to sign in/out. Once you set up the accounts within the app, just select the email account that you want to view. It might be a little more problematic if you want to prevent each other from being able to see the other's email, however.

Is it possible to have your whole family on one apple id or is it better to have each person have there own? If each has their own does each id have to buy their own music and apps? How does find my iphone work with one apple id or two?

How does find my iphone work with one apple id or two? also I am going to be going off to college soon should I make an itunes id for my self and how will I get all the music from the old id?

Is it possible to have your whole family on one apple id or is it better to have each person have there own?
Yes, it is possible. 1 apple ID can be associated with up to 10 devices.
If each has their own does each id have to buy their own music and apps?
Yes, all purchases are non-transferable.
How does find my iphone work with one apple id or two?
Every device associated with one apple ID through Find my iPhone is tied to that Apple ID; Find my iPhone will work in the same way with up to ten devices associated with one apple ID. You cannot enable Find my iPhone for one device across two apple IDs
I am going to be going off to college soon should I make an itunes id for my self and how will I get all the music from the old id?
If you have authorized a computer with the old apple ID, you can transfer old media purchased through the old to other devices via iTunes. This doesn't mean the media purchases through the old apple ID it transferred to the new account. If you plan to make future purchases and don't wish to share them with others, make your own apple ID.

Is it possible to have a Cron job in CPO to check the running status of a workflow

Is it possible to have a Cron job in CPO to check every hour to see if a particular workflow is running, if not trigger it by creating a alert, if yes- autokill

Hi Warren,
We don't want our process to expire and also not to execute twice at once. We have a provisioning wrapper workflow which is triggered one time by an alert and it runs endlessly by creating an alert at the end of each instance triggering another instance of the same unless CPO hangs or goes to stand by mode. Since we belong to service team, we don't have any kind of access to CPO DB or logs, so that possibility is ruled out. Just checking for alternatives.

HT1353 Is it possible to have another iCloud login on my unit without me logging into that account?

Is it possible to have another iCloud login on my unit without me logging into that account?
I lost my iTouch4 last June10 after a party. I stayed in a hotel with my team that night when i lost it --- lost in the hotel not in the party. I just got my new iPhone 4S this June25. When i used Find my Phone app i saw that there are 2 devices: ipod (named after one of my teammates) and iPhone (under my name). whne i check the features of my iPhone, the contacts, calendar, bookmarks and apps i downloaded previously on iTunes are sync to what i entered on my iTouch. My teammate told me that he also noticed that on "his iPod" and he dont know why his apple ID was changed to mine.
Is it possible to get that situation? Or is that an evidence that he has my iPod touch 4? I need help to clear things out. Thanks.

- I do not understand what yo are seeing with the FIndMyiPod app. That app can set up to find any iOS device. you just have to enter the Apple ID and passwords used for that device.
- on your computer go to iCloud, sign into your account and go to FindMyiPhone. What do you find?

Is it possible to have two USB drives for the IPad? I want to bring RAW photo files from my camera, through the IPad and back to an external hard drive. One of my cameras does not use an SD card. How can I do this?

Is it possible to have two USB drives for the IPad? I want to bring RAW files from my camera through the IPad and out to an external hard drive. One of my cameras has an SD card but the other one doesn't have a card that would fit in any of the camera devices I've seen on line. Realted to this, I bought the IPad camera accessory. Can I put the SD card in the device and also hook the external hard drive to the USB port of the accessory and download from the camera to the hard drive? Can I put Lightroom or the Nikon photo editing software on the IPad? Right now I carry a PC laptop and external hard drives with me on wildernes trips. Internet and WiFi are not available. Because I shoot so many photos and they're in RAW I need to download from the camera to the external drive because I run out of memory on the PC (and it has much more memory than the IPad). I have Nikon NX software and lightroom on my PC. I'd love to be able to reduce the weight I carry by using the IPad to edit my photos each night while on trips. Is this possible and how would I do it? I'd appreciate any guidance.

No, the camera connection kit only supports the copying of photos and videos to the Photos app, it doesn't support copying content off the iPad. For your second camera instead of the SD reader part of the kit, does the iPad to camera cable not work with it for direct transfer to the iPad ?
For Lightroom and Nikon software again no - you can only install apps that are available in the iTunes app store on your computer and the App Store app on the iPad, 'normal' PC and Mac (OS X) software are not compatible with the iPad (iOS). There are some apps that perform fairly basic editing functions that are available in the store, but nothing as sophisticated as, for example, Lightroom.
