How to change the fetch size for a one-to-many relationship

With Toplink 10.1.3, since using scrollablecursor is a prerequisites for changing the fetchsize on a query (using the setFetchSize), I am wondering if it would be possible to change the fetchsize of the query which is associated to a one-to-many relationship.
So, is this possible? How ?

In TopLink 10.1.3 you can set the fetch-size on any query, it has nothing to do with using a ScrollableCursor.
Example:
readQuery.setFetchSize(100);
To set the fetch size on a mapping query use,
mapping.getSelectionQuery().setFetchSize(100);
In 10.1.3 you can only set this in code, not currently through XML or the Mapping Workbench. In 10.1.3.1 you should be able to set the value through XML as well.

How to set the fetch size for a ResultSet object?

Connection con = getConnection();
Statement stmt = con.createConnection();
ResultSet res = stmt.executeQuery("select * from table");
//res.setFetchSize(?);
while (res.next)
res.get....
}I do not know the number of rows .
How can I set the fetch size for the ResultSet object?
I try
res.last();
res.setFetchSize(res.getRow()/2);
res.beforeFirst();
while (res.next)
res.get....
}but it's so slow if there are 6000 rows.
How can I set the fetch size for the ResultSet object more effectible?
And what is the best number to set the fetch size?

The fetch size defaults to a standard number. It is unlikely that it will be any faster if you set it unless you only plan to read a small number of rows.
i.e. if you are going to read all the rows, you need to read all the rows no matter what.
Unless the system has set the fetch size to 1 changing it will not be faster.
Depending on the row length, reading in 6000 rows is going to take a long time. You could try using a cpu profiler to improve performance.
Do you really need to read everything in every row?

Don't specify the styleclass for the inner panelHeader.

How does one change the font size for folders and/or file lists in the Bookmarks Library?

How does one change the font size for folders and/or file lists in the '''Bookmarks''' Library?
Since the upgrade to version 9.0.1 of Firefox, the Bookmarks feature changes are confusing me. They seem to be confusing themselves as well. The list of bookmarks has changed. The font size is so small that my aging eyes cannot read it without fogging the screen with my breath. Some folders are out of alphabetical order (where I know they were previously good), and some are missing altogether (folders to which I frequently add references).
As for missing or deranged files or folders, was there something that I should have done or now need to do to recover those after the upgrade (or before)?
With regard to font size,
1. there is no “Edit Bookmarks” or like option to edit the list in this version
2. the “zoom” option in the “view” list of functions is greyed out when in “Show All Bookmarks” window
3. expanding the browser window has no effect on font size
4. “Preferences” settings for font size has no effect in that window either, including advanced settings
5. “Help” offers none that I can find.
Can any of you Help?!?

Maybe this extension helps:

I cannot figure out how to change the photo size on my iPhone 5s. I was given the choice of small, medium or large the first time I took a picture. Now I have no idea how to change it to medium. Can anyone help?

I cannot figure out how to change the photo size on my iPhone 5s. The first time I took a pic it asked if I wanted smalll, medium or large and listed the pixels. I chose small but am now finding that is too small. Can anyone help me set it to medium now? I can't find any setting for that. I'm a newby to iPhones and have no idea what I'm doing. Thanks for any help you can offer.

By "sending" do you mean sending email?
If so, what app are you using to take the photos on your iPhone 5? Or are the photos from a different source (saved to your Camera Roll from somewhere else, like a web page or Messages)?
My guess is that Mail gives you the option to send different file sizes when it detects you are trying to Mail a really large photo file. The size of photos on the iPhone 5 is really big and some email providers may stop your mail from being delivered if attachments are too large. Thus, Mail tries to help you by offering to resize the photo.
I suspect that if you are sending smaller files, Mail does not bother giving you options to save a smaller version. In fact, I have seen this behavior. So, if the photo is already "small enough", it gets sent as-is.
To my knowledge, there is no global iOS setting for this. Some apps may have different rules, of course.

How to change the font size of text element in smartform

Hi
i want to know how to change the font size of text element in smartform
regards
Gincy

Hi
You can create Smartstyles, in which you can define paragraph formats for texts and character formats for character level changes.
Paragraph format ---> alignment, font size etc
character format for ---> superscript, subscript.
After creating, in your smartform, there will be a option in the text element to enter a style.
You give the created style and you can use the paragraph and character formats i that style.
Hope this is clear..

Do this with each field.
Or if you have a lot of fields:

How to change the font size in sap scripts?

hi friends,
i had a query regarding to SAPSCRIPT.
how to change the font size of a text in sap script form in which it should change it dynamically.
is it possible to change the font size dynamically in scripts.
one more query regarding to this only.
i need to get the hard copy of a script .
what is the transaction code to get the hard copy?

Hi venkata,
You can specify the font size either in the Character format or pharagraph format.
You better decide it according to your requirement. If you want to apply the same font size for the entire form create the Paragraph format and give the paragraph format in the default paragraph format.
If you want to apply that to limited text, then create character format.
The process of creating it is just after going inside paragraph format click EDIT-> Create Element and give the font size.
This applies for character format also.
Reward points if useful.
Thanks,
karthik

I like the mail feature with one exception; I cannot figure out how to change the font size of incoming mail permanently. And, when answering an email I have to highlight the first few words and zoom it so I can see what I am writing. what am I missing?

I like the mail feature with one exception; I cannot figure out how to change the font size of incoming mail permanently. And, when answering an email I have to highlight the first few words and zoom it so I can see what I am writing. what am I missing?

You can type the email using what you set in preferences and then highlight the text and use command - minus sign (or command - + for larger) to reduce the size of the text.
You can also type command - T and a window will appear allowing you to select fonts/sizes/color/ background highlight.
The above works in Notes also. I haven't tried to do this in any other Apple application.
For incoming emails, you can use the above to reduce font size, but I don't know of a way to permanently set the incoming font size to a default.

How to set the stack size for alchemy application?

Anybody know how to set the stack size for alchemy application?
If you know, please tell me how to adjust the stack size for alchemy application?

Hi,
The stack size is set as public const gstackSize in the alchemy generated code. You can see this if you build with ACHACKS_TMPS set. The default is one megabyte.
One way to change the stack size is to use llvm-dis to disassemble avm2-libc/lib/avm2-libc.l.bc, generating avm2-libc.l.ll, modify the constant, and then use llvm-as to recompile your modified library and overwrite the old one. These utilities should be in your path if alchemy is set up.
