Would removing some rows cause Row Currency issues?

Here is my story
Clicking a link goes to a table. The table looked fine, scrolling to next page as expected. For some strange reason, I started getting row currency errors. So I added "EnableTokenValisdation=false" on pagedef. Then I realized that I could not scroll to the next page. It has like 50 records. However, when I try to go to the next set (or if try to View All records), I get no row found. Why? Help!
Now I am stuck.

Frank, I agree. I removed the kludge.
Now, how can this happen. I have a application that worked.
I remove some rows from the database using sqldeveloper.
I retry the same app and I get row currency errors. Is this a possibility and if so, what can be done or how can I find the problem?
I have closed the app several times, deployed it, rebuilt uit several times.

Migrated/chained rows causing double I/O

" You have 3,454,496 table fetch continued row actions during this period. Migrated/chained rows always cause double the I/O for a row fetch and "table fetch continued row" (chained row fetch) happens when we fetch BLOB/CLOB columns (if the avg_row_len > db_block_size), when we have tables with > 255 columns, and when PCTFREE is too small. You may need to reorganize the affected tables with the dbms_redefintion utility and re-set your PCTFREE parameters to prevent future row chaining.

This is one of the better observations that you can get from the Statspack Analyzer. It would be helpful, though if it compared the number of continued fetches with the number of rows fetched by rowid and rows fetched by tablescan to produce some idea of the relative impact of the continued fetches.
It is possible that this advice is a waste of space, though --- and we can't tell because (a) we don't know how long the interval was, and (b) we don't know where your system spent its time.
If you care to post your statspack report, we might be able to give you some suggestions of the issues that are worth addressing. If you choose to do this (a) you may want to edit some of the text to make the report anonymous (database name, instance name, components of filenames, all but the first few words of each "SQL ordered by" statement).

EjbRemove, remove(), bean logic, database row logic

In some Sun examples the remove() method is not exposed trhu the home interface, but anyway it is called from the client thru the home interface, I would like to know the reason; another question is the logic after the remove() method exposed thru the remote interface versus the ejbRemove() method exposed (?) thru the home interface, so the question is:
- there is a logic directed to the bean (to delete de entity bean) and another logic directed to the persistent row represented by the bean?.
If I delete a row it is obvious the entity bean representing it should be deleted, but what happens if the client (or the container) invokes ejbRemove() either directly (the container) or trhu the home interface (the client) and I only want to delete the bean, but not the persistent row? Iin fact, the container could call ejbRemove as part of the bean lifecycle, and this should not imply the persistent database row delete, so it appears that the row delete code should not be in the ejbRemove() ?!
thanks.

I think that that the removing of an entity ejb should not imply the removing of the database row, thought the remove of the database row really implies the removing of the entity ejb representation. So, if you code an sql delete statement in the ejbRemove method, it implies that as consequences of the lifecycle of ten entity bean the row could be removed, and I think it is not allway rihgt, for if you want to remove the ejb representing your account (for example), to free server memory, it should not imply that yout account database row should be removed too, unless the ejbRemove method woulnd't be never called by the container, so, to cut it short: what happens if the container, as a consequence of the lifecycle of the bean, call ejbRemove and you coded in this method a sql delete, your account (for example) in your bank would dissapppear!, and you only wanted to free the memory associated to the entity ejb.
I think the remove() and ejbRemove() are tricky!
Maybe I don't understand well the basics of ejb, but I really thought a lot about this question.
thanks!

An alternative is to use a 12v USB power plug and then just use the standard lightning cable to connect with a length of your choice ( to some degree)

The first time I synced my iphone 4 with my mac, I didn't realize that all of my photos from the iphoto library would transfer over to the phone (more than 3,000). Now, I need to remove some, as they are taking up too much space. I cannot figure out how to remove them from the phone.

Render table with some of the rows unselectable

Hi all,
I am using JSF for GUI development, i have a requirement wherein i want to render a table which has a column of checkboxes for selecting row(s) in addition to that i want that when the table is rendered based on some condition, for some of the rows the checkbox will remain disabled and for some it will remain enabled.

I was expecting that you've a problem with Sun JSF RI (Mojarra). For other JSF implementations and libraries you'll get quicker and more accurate response at the forums or mailinglists of the appropriate manfacturer. Sun hasn't manfactured Trinidad, Apache did.

OS X causes Google Earth to crash. Would appreciate some solution.

I just downloaded Mavericks and found immediately that Google Earth would crash as soon as I typed anything into the search bar or clicked on history. Tried several times to down load Google Earth again but each time the same issue occurred. Would appreciate some solution if there is one. Many thanks.

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

BPC 7.5 AfterRange Causes Extreme Performance Issue

In a report when I apply second AfterRange the run time goes from under 2 minutes to 15 minutes. I know there are performance penalties for using Before/AfterRange but I have never seen the discrepancy to this proportion.
Report contains 1 Column (Time) and 4 Rows in Expansion. The first range which causes no issues for Cost Centers is defined Q73:V74, the range which causes the performance issue and applies for each Employee is defined as Q71:V72
To test this I have two versions of essentially the same report, one with only Cost Center AfterRange and this version runs in less than 2 minutes, then I have the other version in which I have added one more AfterRange to another column and that's when the hell breaks loose and this version of the report runs in 15 minutes. The number of records is roughly 2000, and I realize that the range causing the issue is applied on pretty much every rcord in result set but still I'd not expect the run time to increase by this much.
BPC Experts, ideas on what could be causing this issue, any help would be highly appreciated. thanks!

Merging multiple rows in to a single row (when rows meet merging criteria)

Hi
I have a scenario to merge multiple rows in to a single rows when the data in those rows fall in merge criteria .Below is how my data is
Now the merging logic for the above rows is , we need to combine multiple rows in to a single row when the data in those rows permits us to do in that way. Simply saying , its like sandwich where we combine multiple things to a single piece.The output for
the above rows should be
Here we combined Row 1 ,2, 3 in to a single row as the data in those rows permits to merge in to single row. But the row 4 cannot be combined to any of those rows because the data in those rows doesn't permits us do a merge ( As the value of the column
JobSource for the row 4 is different from the other rows ) .
My original data has 56 columns , but for readability i kept only 9 columns.
can you please throw some idea on how to achieve this scenario. I know we need to use CTE for achieving this, but i am not able succeed in doing an iteration on multiple rows.
Appreciate your response .

Thanks for your reply .
Rule for merging is simple . First of all there is no unique row identifier for each row , the fact table is not having an identity column in the database . I called row 1 , row 2 etc in my post above only to make better explanation of my scenario.
The rule for merge is below.
1) we can combine only when the data in a column for one row is null & the data in same column for the other row is not null . It should also satisfy the condition where the data in other columns should conflict each other.
2) Data for all columns for the merging rows should not be conflicting (i.e. we should not merge the rows when the data in a column is not equal to the same column in the other row
,considering not null value)
Steps in merging the above source data :
1) Consider the case of row 1 and row 2 in the source, we can combine these rows as the data is satisfying the rule 1 for columns (Jobsource,Flight, Package,Update,Iscancelled
,Result, Severity) and columns (JobID and RuleName ) fall under rule 2. we merge these two rows in to a single row and keep in that in the table.
2) Then the resulting row is again merged with the second row which is present above by applying the rule 1 and rule 2 . Below would be output of merge operation.
Now there would be only two rows in the output . But these rows cannot be merged as the data doesn't satisfy the merge rules 2 . As Jobsource for the row 1 in the above output is "PresubmissionSource" which is not equal
to "PostSubmission" jobSource which is in row 2. So these two rows are left unmerged .So the above two rows would be the output of merge operation on my source data.
This process has to be repeated for all the rows in the table. As of now my table as 92 Million rows with 56 columns which need to be considered for merging rows. I replicated my scenario in 9 columns and 4 rows to understand better.

Can you remove some of the Default applications

I want to give an iPod Touch to my mother who is technically challenged and doesn't have WiFi.
I only want the iPod functionality, not the browsers, email, maps, or any other feature.
Is there a way to disable or remove default apps that you don't want?
ps: I do not want an iPod classic., it''s interface is harder to learn than the touch.

I too would like to remove some of the default apps. Personally, I find the YouTube, Stocks, and Maps, useless to me and its just a waste of icon space. And whats with the "The touch may not be for you". Seriously, if someone wants a touch but doesn't want some of the default apps, that doesn't mean the touch is not for someone. I think it would be a smart move for Apple to revise the iPod (and iPhone, if people can't remove default apps on there) so that we may remove the default apps that we don't use. It makes absolutely no sense to just "move" the app to the back if we don't even use the app. That's like saying "you may not have any use for this app, but its here because we want to force you to keep the junk we give you". And it sounds a lot like a Microsoft move for the all the Windows operating systems they have released (up to Vista, so far) forcing Internet Explorer on all its users and not allowing us to remove it because it was integrated into the Operating System. Supposedly, Microsoft is growing up and letting the user to actually disable (maybe even remove) Internet Explorer in the upcoming Windows 7. What about Mac OS X, does it force Safari on its users, like its forcing some of these unnecessary apps onto the iPod Touch? I wouldn't don't know, I don't earn quite enough money to buy myself an iMac or MacBook (and I've even heard from several people that its more expensive to get a gaming Mac than a gaming PC with similar hardware configuration). Only Apple product I own so far is an iPod Touch.
But I will give Anna credit. Anna at least answered the question.
The question was "Can you remove some of the default applications" and a response saying "What is your mother going to use it for? Maybe the Touch is not the right device for her." by "D'Fish'N'Seas" does not answer the question at all. The question has nothing to do with what the mother is going to use the iPod for, so don't post a response like that, its one of the reasons that causes short tempered people to flame other people.
Ok, so since Anna answered the question that Ron asked. I have a question related to this topic, and if Ron is still wanting to remove some default apps, I'm sure he would like an answer to the question too. So, here is my question: Has anyone developed an app that would allow us to remove the default apps, or a tool that will guide us in removing some default apps?
And preferably the app or tool be in the most legal possible way. Wouldn't want to ask for something that is illegal.

PS CS2 lens correction causes "Maximize Compatibility" issue in LR

Question: why does PS CS2/3 convert the layer "Background" to "Layer 0"?
This is the problem (and solution):
I encountered the widely discussed "Maximize Compatiblity" issue with a bunch of PSD files (slide scans) that contained only one layer. Puzzled as I was that the layer thing apparently could not cause the problem, I reopened some of those files in PS CS3 and I noticed that each of them had had a lens correction. Just to make sure I was on the right track I applied a lens correction to a file that had been already imported into LR successfully and used the SaveAs command and unchecked the Maximize Compatibility option. The new file could not be imported into LR. So no more lens corrections? - I thought.
A closer look on the troublesome files made me learn the (only) layer had been renamed from "Background" to "Layer 0" after the lens correction was made. I used the "Flatten Image" command and this turned it back into "Background". After this, the file could be imported into LR without a problem.
I can now apply this trick to all troublesome files that have had lens corrections and thus avoid the huge increase in file size (130MB is a lot already).
Now I write this for those of you who have the same problem and are still puzzled (to help out) but I also would like to have some insight into why PS CS2/3 lens corrections mess with the layers.
Thanks.

>My conclusion would be that LR can only import PSD files that meet the following requirements:
>1. must contain only one layer
>2. that layer must be called "Background"
Your conclusion is only partially correct.
Lightroom will import multi-layered PSD files that have been saved with the preference for "Maximize PSD and PSB File Compatibility" set to On. This is clearly stated in the Release Notes and Help documents:
>Photoshop format (PSD)
>Photoshop format (PSD) is the standard Photoshop file format. To import and work with a multi-layered PSD file in Lightroom, the file must have been saved in Photoshop with the Maximize PSD and PSB File Compatibility preference turned on. Youll find the option in the Photoshop file handling preferences. Lightroom saves PSD files with a bit depth or 8 bits or 16 bits per channel.
As to the original point -
PS CS2 lens correction causes "Maximize Compatibility" issue in LR.
Photoshop renaming Background Layer to Layer 0 is a Photoshop issue, not Lightroom. When it occurs the files effectively becomes a multi-layered file, even if there is only one layer (i.e layer 0). Why using the Lens Correction filter causes the background layer to be renamed is currently unclear, but I have raised it in the "appropriate" place. In the meantime, I recommend that you set the Maximise Compatibility preference to
Always. Doing so will save non layered files as normal and multi-layered will have the
necessary* composite preview. You can continue to use the flatten command to fix the errant files.
*Enabling the Maximise Compatibility preference ensures that Photoshop creates a composite preview of multi-layered images. It is intended to enable applications that can't read layers to preview the images. Lightroom cannot read multi-layered files, therefore the composite preview MUST be present in such files.
>Has anyone noticed different behaviour with the Lr v2 beta? I'd hate to double the size of all my multilayer PSDs just so they can load into Lr(?)
Lr 2.0 will function as per Lr1.x; i.e. not using Maximize Compatibility when saving multi-layered files will mean that they are not compatible with Lr2.0.

Query for row by rows-before using seq number

Hi,
I have a table of CatalogAuthor records
long : id
varchar : author
long : seqnum
I have made the table so that initially, if there are 10000 unique authors, then the rows will have sequence numbers from 1 to 10000. As authors are dynamically added, they are given the sequence number of an existing row in the table, i.e. the nearest row whose author comes before the new author. As time goes there are more and more duplicates, and at a certain point, the table has all its sequence numbers reassigned to be monotonic increasing by author name order.
We want to use this table to build a tree of about 10 nodes per parent, culminating in author names. So to expand the tree at the first level, we could divide 10000 by a suitable power of 10 to get the groups of sequence numbers. However, with duplicate seqnum, there may be 14365 rows so ideally, to overcome the problem of clumping, I would do some kind of query to identify the 1436 record in sorted order by sequence number, the 2872 record by seq number and so on.
What query would that be? With appropriate indices, would it still be slow? Would I have to do 10 of these queries to expand one node with 10 children? Is there a better design to accomplish the same goal of exploding a balanced tree by author name sort order, culminating in a leaf of one particular author?

What will this tree structure do for you that an index on author won't do?
I don't know of any way to automatically keep a tree balanced every time DML is done.
You could periodically re-balance the tree; that shouldn't be too hard. Let's say you want each parent to have up to r children. Use the analytic ROW_NUMBER function to assign unique numbers 0, 1, 2, 3, ... to each row, in order by author.
The row numbered 0 will have no parent
For all all rows numbered n (n > 0), the parent will be the row numbered FLOOR (n/r).
Whenever you re-configure the tree, use a MERGE statatment. An index on author will probably make generating the ROW_NUMBERs faster.
If you need help, post CREATE TABLE and INSERT statements to show the table as it exists with the tree out of balance, and also show how you want it to look after balancing. Use a small value of r (maybe 2 or 3) to keep the sample set small.

BUG - remove hidden information - Acrobat remove some visible/live text (in all Acrobat versions)!!!

hello
I need to check many pdf for hidden/clipped text and remove them. Acrobat can find this BUT have bug.
Acrobat mark some live visible text and this is problem if you click "remove" button.
Here is evidence (6):

It was strange in my copy of DC, but I selected the Redact tool and then remove hidden information. I highlighted the hidden info in both files, but then backed out, not doing the remove. When I tried again, the remove hidden tool was blocked. When I actually did the removal, those items were missing as you mentioned. I am not sure why they were listed as hidden since they were indeed visible. I am not really helping answer the problem, but confirming your results.
Also, if you select remove hidden information when closing the document, you lose these fonts characters just as when using the Redact tool. I would agree that this is indeed an issue for a bug report. An earlier post provided the bug report link and I would suggest using it.

I am trying to copy a document and I keep getting the error "Can't paste the objects. The requested transformation would make some objects fall completely off the drawing area."

I am trying to make duplicate documents with minor adjustments to each and when I try to copy the artwork from one document and paste it into the new document I keep getting the error "Can't paste the objects. The requested transformation would make some objects fall completely off the drawing area." Both documents are exactly the same size, res, color format etc. I even tried to drag and drop and get the same error message. Anyone know what I can do to resolve this issue?

Try scaling the view size down to 6% or so and then do a Select All. See if there are objects off the artboard which may be causing this error. Most often you will see this if there were guides dragged from a ruler which were selected by dragging the white arrow and then deleted. This leaves the anchor points at the edge of the work area.

Would removing some rows cause Row Currency issues?
