Look ahead LOVs

Hi,
I guess look ahead LOV feature is available in the latest OAF build (R12 version). I was trying to achieve this functionality but was not able to do so. As per the guide, I created messageLovInput filed and tried adding Look ahead LOV. After typing some character, instead of getting matching records, I was getting the message "Message FND_LOV_DATA_PROGRESS not found". I couldn't find any details about this message.
Can anybody help me with this?
Thanks in advance,
Shree

Hi
I have implemented the same and i am not facing any issues with that. Try to run simple LOV and remove all the properties for LookAheadLOV .Check whether it runs or not.If it runs then change
Look Ahead Enable : True
Look Ahead Search Type : startsWith
Minimum characters : 1
This should solve your problem.

Look Ahead Lov dosen't work for SubTab layout

Hi,
I have developed a custom page which can have multiple tabs.
When there is only one tab, everything works fine. Now when i try to copy a bid , which opens a new tab, and try to enter a valid value in the LOV field. I get a message saying 'Unable to fetch results. Please invoke the LOV window for search results'.
One more Observation here is , when an invalid item is entered and tabbed out, the Lov window should open up automatically. Which doesn’t happen for the second tab. Everything works fine when there is only one tab.
Please assist on this issue.
Thanks

same problem here. Has there been any update on how to fix it?

Implementing an Effect that looks ahead in the source

Hello all,
I need to create an application which reads from one AVI file, processes each frame with a special effect, and outputs the result to another AVI of the same format. Fairly standard stuff.
I am fairly new to JMF but I think I have the basic methodology right: creating a Processor, and then during the Configured state, adding a new Effect to the Codec chain of the Processors first TrackControl.
The thing I am unsure about is this: the Effect I am programming needs to 'look ahead' in the source i.e. it needs to see frames 1, 2 and 3 before it can write frame 1 of the output.
Does the process(Buffer input, Buffer output) method of Effect is called for each frame of the video, providing a Buffer for each frame at a time? In this case can I buffer the first three frames for myself, and withhold output until the third frame?
Or is process(Buffer input, Buffer output) called once by the Processor, with the in/out buffers represent the entire stream and able to be read and written to 'asynchronously'? In this case, when I use javax.util.BufferToImage to get my actual frames to apply the effect, do successive calls step through the frames, how do I reference specific frames from this context?
I'll stop speculating now - I hope someone can nudge me in the right direction... Thanks very much for any advice.

Hello Darkmoon_UK,
Your problem seems similar to my one.
I want to implement a slow motion effect with jmf. I also read from an avi file.
First thing I hava to ask is, whether your effect simply plays the original video into the new file, if you only add
output.copy(input);
into process()-method.
I dont't know if it is important, but I add the new Effect to the codec chain AFTER ConfiguredCompleteEvent, not during Configured state. And this works (at least simply playing the video works, not my slow motion effect ;-) ).
Next thing is you should insert some System.out.println()s into your process()-method code to discover that it is called several times (for each frame of the video).
I think it is possible to buffer all the frames into an collection out of java.util.* and make a specific variable (int frameCounter) count the frames by calling frameCounter++; at the end of the process()-method. Same effect is using input.getSequenceNumber(), I think. With the help of a Collection of java.util (ArrayList or something else), it should be possible to access any frame out of the video.
Well, I'm also still learning and trying to force JMF to do what I want, not the other way round, as it is at the moment. I hope this little bit of information I gave you could help you solve your problem or at least nudge you in the right direction.
Bye,

Possible to look ahead with a cursor

I need to know if you can do sort of a cursor look ahead and view data from the next row in the cursor. I'll try to succinctly explain why, maybe there's a better solution.
We have several items that are valid through certain date ranges. The database was designed to only hold the starting date of an item, thinking that the end date could be calculated by looking at the start date of the next revision of that item. For instance:
Cert1 version 1's start date -> January 1, 2000
Cert1 version 2's start date -> January 1, 2002From that we can deduce that Cert1 was valid between January 1, 2000 and December 31, 2001. Unfortunately, this isn't working out quite like I expected in my function because I don't have access to the second version information until AFTER I've already processed version one's information and the processing of version one is dependent upon the data in version two. I'm sure you can see where this is headed... =)
So is there a way I can read something out of the next row, without moving the cursor, or will I need to redesign that particular table in the DB?

Hi,
You can get the value from the next row right in your result set, using the analytic LEAD function.
For example:
SELECT start_date
,     LEAD (start_date) OVER ( ORDER BY start_date)     AS next_start_date
...LEAD returns NULL on the last row in the result set.
If you have several different groups (say, different items, identified by item_id) and you want to find the next start_date in the same group, then add a PARTTITION BY clause:
SELECT item_id
,     start_date
,     LEAD (start_date) OVER ( PARTITION BY item_id
                                 ORDER BY      start_date
                      )     AS next_start_date
...See the [SQL Language manual|http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/functions079.htm#sthref1560] for more.

Reporting on milestones with a 2 week look ahead?

Hi,
I'm pretty new to my role as project planner (it was kind of thrust upon me) and I'm still getting my head around Project.
I'm working on a programme and each PM has their own plan in the template that I created. I have taken the milestones and deliverables from their plans and built my own "integrated plan", showing just milestones and deliverables.
My programme manager would like a report that easily allows us to project to the team their milestones with a two week look ahead, and a view of the previous two weeks, so that people can see just how much they're slipping by etc. I've messed around with
views and filters but I can't get it to show what I want. Is what I want achievable in project or do I need to export it to Excel or something else?
Any help would be greatly appreciated!
Thanks.

Hi
Dewsey83,
An example of what you want to achieve would be good. If, for example, you are looking for all the tasks that are supposed to have some work executed over the period then the formula for the flag field can be something like:
IIf([Finish]>=Now()-15 And [Start]<=Now()+15,1,0)
and if my project plan is the one below, note that any work scheduled over the specified interval will drive the Validation field to be set to Yes:
and if I use a filter like:
I will see only the tasks that will be executed over the period

Oracle Read-Ahead: not the same as look-ahead, yes?

Hi,
I've tried to understand the Oracle Read-Ahead systems, and I think I undersand how it works, though I'd like to assert that I am not mistaken.
From what I've managed to understand in the Oracle documentation, the Oracle read-ahead mechanism is mostly used for sequential accesses of data blocks. For example, to perform operations like table scans.
In such cases, Oracle will for example use a physical operation called scattered read.
The scattered read, in turn, is configured in the ini.ORA by a parameter name something like db_multiblock_read_count. Having a multiblock read count of 60, will make the scattered read operation read 60 sequential data blocks from disk, starting with the data block that was requested in the operation.
From what I've gathered, this is the basis of the Read-ahead mechanism. It is use mult block operations do read data instead of single bock operations.
If what I've said so far is correct. There are two things that I'd like to know:
1.
Those 60 blocks read by the sctarred read. Do they go directly into the database buffer cache? Or are they loaded first in to a lower level cache, like a scattered read cache?
Thus, if the table scan requested the page 1. And the scattered read operation fetched the database pages 1 to 60. I assume that only page 1 would be transfered to the buffer cache. Later on, when the table scan requested for page 2, the buffer cache would retrieve that page from the scattered read cache into the buffer cache. Or is this completly wrong? And when the scattered read gets pages 1 to 60. It automatically dumps those data pages into the buffer cache into random positions of the main buffer?
2.
With Oracle read-ahead, table scans and other such physical operations will always incur scattered read waits periodically. For example, every 60 pages the table scan incurs in another scattered read wait correct?
3.
Reading-ahead In oracle only anticipates the database page needs of a physical operator a specific point in time, yes? The following does not happen:
While the table scan is currently on page 50, having another 10 more pages left in the database buffer, some background process decides that it is a good idea request another fetch for 50 more data pages. In such a way that the forground thread processing the table scan never has stop in read IO.
This would be called looking-ahead, and it is not an Oracle feature, is it?
Thank you for your insight.
I've performed some tests where though the table size of a data transformations remain the same (1GB) but the time I take to process the source table into my output varies. The processing time for each record increased greatly from test to test. But I noticed that the wait time of the data transformation remained constant, though the cpu time increased greatly. THe increase in CPU time means that the Time Until Next Buffer fetch was reduced, which would give more time for the system to look-ahead. Eventally I could have made the CPU time so great, that if REad IO was being performed in anticipation it would be theortically possible for the READ wait time to be 0. Which I know is not going to happen. So I'd just to be certain of how the read-ahead works.
My best regards.

Am not sure if you meant reading multiple blocks at the same time or Read ahead cache features provided by some storage devices. But to me it seems you are talking about MBRC (Multiblock read count) and not about read ahead cache provided by storage vendors.
If what I've said so far is correct. There are two things that I'd like to know:

And when the scattered read gets pages 1 to 60. It automatically dumps those data pages into the buffer cache into random positions of the main buffer?
If my mbrc is 60, and none of the blocks are in buffer and table size is more than 60 blocks then entire 60 blocks would get transferred to buffer cache. There is nothing called scattered read cache in the architecture of Oracle.
2.
With Oracle read-ahead, table scans and other such physical operations will always incur scattered read waits periodically. For example, every 60 pages the table scan incurs in another scattered read wait correct?
Yes db file scattered read wait event would mean that another physical IO has been initiated for fetching next blocks of records.
3.

While the table scan is currently on page 50, having another 10 more pages left in the database buffer, some background process decides that it is a good idea request another fetch for 50 more data pages. In such a way that the forground thread processing the table scan never has stop in read IO.

Yes I do not think so it is an Oracle feature but some storage vendor provides it. It is also known as Read ahead.

Look Ahead Routing

Just need to understand the look-ahead feature implementation on the IOS.
Scenrio -- two locations with their local PBX and voice gateway routers. Trunk connection to the Cisco router (T1/E1 trunk). Network has set bandwidth for the voice calls.
How the router at location-1 gets the status of the location-2 router in real-time that RESOURCE NOT AVAILABLE and in-turn inform the PBX. In this case, PBX will re-route the call using alternate path. IS look-ahead routing option available on the IOS?

it is not quite understand what your question is.
what do you mean when you say "RESOURCE NOT AVAILABLE"?
if you mean lost ip connectiviy between gateways, then you should use local voice busyout feature.
or do you mean something else?

Where to look for LOVs on a page

I am debugging an application that has 3 LOVs. I see these 3 LOVs on few pages but I don't see how it they show on those pages.
Where should I look to find out how these LOVs were linked to a page???
Thanks

I can see they are part of page 0 but still don't know how they are linked to other pages.
Alright, I see that page 0 will show on all pages conditionally.

G4 PB on the rocks... looking for love.

Have a 15" G4 PB about 2 yrs old, 1GB RAM, been real sweet to me... until lately. Its starting to show signs of aging; gets hung from time to time, real slow to do some things, seems to get confused, disoriented, moody, even disinterested. I took it out to a nice dinner the other night, it didnt even want to eat... Not sure if its a hw or sw(OS) thing, but just looking for some suggestions as to what I can try to reinvigorate our relationship, make it feel new and exciting again. From what I understand, OSX does a reasonable job of disk mgmt, so defragging isnt something that we really need to do... or is it? (just remembering the ol' IT job, defragging PC's left and right) Does the OS just need a rebuild? I have room for another 1GB RAM, but I thought that 1 should do fine (its not how big it is, but what you do with it, right?). HD sounds fine, no grinding or clicking. Battery does need replacing tho; 100% bat takes about 50mins to run down.

gnads:
If you want to be real nice to that woman (PB), give her some regular attention, otherwise known as maintenance, and she will do anything for you in return. If you have never done it before, and if you are not up with your PB between 3 and 5 a.m. you are likely to be badly in need of Unix Maintenance (CRON cleaning). Below you will find links with suggestions and links to resources that will make that baby really feel appreciated.

How can I upgrade to new versions, but keep the custom look I love icons of the theme I've installed in version 3.6.n ?

When will custom icons in themes be available for the new versions. The stripped down m9inimal version is just not appealing to me.

First, try to determine the reason that Firefox 3.5.10 is hanging or not starting. Since you did not specify, you will need to read some of the following to determine hanging or starting; hanging usually gives you an error message when you try to start Firefox. See below. If you install Firefox 3.6.6 over the top of 3.5.10 and the cause of the hanging or not starting is one or more extensions or plugins or some other cause, Firefox 3.6.6 may experience the same problem.
'''Kill Application'''
In Task Manager, does firefox.exe show in the '''Processes''' tab?
See: [http://kb.mozillazine.org/Kill_application Kill Application]
'''Causes and solutions for Firefox hanging at exit:'''
[[Firefox hangs]]
[http://kb.mozillazine.org/Firefox_hangs#Hang_at_exit Firefox hangs at exit]
[[Firefox is already running but is not responding]]
'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''before''' starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See:
'''[[Troubleshooting extensions and themes]]'''
'''[[Troubleshooting plugins]]'''
'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it by enabling '''one at a time''' until the problem reappears. '''You MUST close and restart Firefox after EACH change''' via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

Issue in standard LOV after extending the VO

Hello All,
My requirement is to restrict the LOV "Payment Document" of standard page "PsrPG.xml".
Path of the page :-
oracle.apps.ap.payments.psr.webui
I have extended the VO and implemented my logic to fulfill the requirement. Its working fine if I click the glass icon and try to search in LOV window .
If I enter the same value in the base page field and tab out then also it is working fine means I am able to select the value.
Issue :-
If I use the look Ahead feature of oracle then the matching records are appearing in the Look Ahead LOV window but when I select any of that record it is opening the LOV window "Pop up Window" and says no record found.
Any help on this is greatly Appreciated.
Regards
Karan deep.

What Mac should I look at?

Hi all,
I'm interested in getting a "new" Mac. I'm looking at a slighly old or refurbished Mac given the tough econonmic climate for me personally. I currently use a MacBook 13" from late 2006, and I think I got a lot of milage out of it, I often have referred it to an expensive netbook, and I have realized recently it was a lower end notebook. I know a lot of the Apple hardware for the Macs, I'm struggling to decide my next Mac based on what my future applications I will be using the Mac looking ahead
I am doing a lot of the following recently (or starting to plan future uses:)
Editing RAW photos with my DSLR camera
Using virtual machines on a desktop level to test out servers, app severs, and even using it for old DOS gaming with VMware's Fusion, ideally running at least two at once
Potentially doing Standard Def digital video editing with Final Cut Pro.
Continuing to use the argumentively best Mac OS X, Snow Lepoard (10.6) probably beyond its EOL.
I was looking at a quad core Mac Pro, but recently I was siding to lean towards a MacBook Pro, even though I carry my iPad and iPhone almost all the time.
I have a few questions:
Are the MacBook Pros anywhere near a "desktop replacement"?
Does the CPU overheat or the fan goes off all the time? (hopefully a lot less if I am using a higher end notebook)
Dual Display: according to the Mactracker app, both the MacPro and the MBP support dual display. Does the MacPro support something like a quad display? When that term applies to the MBP, does it count the built in display and one external display or can I actually use 2 external displays?
My question is am I better off using a MacPro for more hardware reliablity or is the MacBook Pro more of a want to carry a Mac wherever I go by cutting corners for convience?
I'm looking at my next Mac to last for the next 5 to 7 years.
Appreciate in advance for answers, and if I didn't make any sense, please chime in.
Thanks!

The answer for your indicates are the Mac Mini, which you didnt mention.
You said youre on a budget.
A current maxed out non Retina macbook Pro (just discontinued) is almost identical specs to a current quadcore mac Mini
havent you considered a Mac mini?
I got a couple macbook Pro, 2 mac mini, Imac and macbook Air. Love the Air best of all of them, but the mac minis are just inexpensive fast workhorses
Mac Mini was recently rated "most popular desktop computer EVER"

Calendar events one hour ahead

Hi
Just got my new 4s and have synced my calendars between Outllok on Windows 7 and my phone. I have an evet that runs every Friday between 18:45 and 20:00 which is set up as a recurring event. It displays fine on my calendar at the minute by looking ahead to the end of march the time displayed seems to have shifted forward an hour to 19:45 - this I believe coincides with the change to BST. Obviously my event still hapens at 18:45 and I would like the calendar to display this. The strange thing however is when I go in to edit the event on my phone - on the edit screen it shows as 18:45, yet when I save this it still displays as 19:45 on the event screen ....
Have I set something up wrong? Can I do something to get the calendar to display correctly?
Thanks in advance
Nigel

Thanks for the above - played around with setting etc on my phone but with no luck. The only way I seem to be able to get the correct time to to create two recurring events - one until BST and the other after which is hardly ideal - I must be doing something wrong!! Just noticed that exactly the same thing happens on my iPad
