Can I set JVM memory size when running applets?

Hi,
I have downloaded an applet that renders panoramic images and
I have a problem with Java memory. I remember that default maximum
size that applet can use is 70MB, and the problem is 70MB is
not enough when rendering big images. It is OK when I add
"-Xmx -Xms" parameters in the Java Control but I cannot tell
everyone who wants to see my images to go control panel, add
parameters etc..
So my question is...
Is it possible add "-Xmx -Xms" parameters inside the applet file
so that these parameters run automatically when executing applet?
Thanks in advance for your reply!

HyungA potential workaround I would try is is use ByteBuffers

Can we set the window size of the applet dynamically

if we have embeded applet as <applet code="some" height=200 width=200></applet> can we dynamically increase the size of the applet dynamically ie., width and height.

yes you can with javascript

Memory Leak when running Contacts

I am having a big memory leak when running the app Contacts on a MB Air. It gobbles up 2 GB of ram in just a few minutes forcing a reboot. I have re-installed Mountain Lion 10.8.2 and it still leaks memory. Watching Activity Monitor shows the rapid increase in Ram being gobbled up by Contacts. Used Mackeeper to clear cache as well as ran Cocktail, all to no avail. Any tips would be greatly appreciated.

The size of oracle.exe is not an indication of how the Java VM GC works; so you are not comparing apples to apples. It'll be too long to explain here but in my upcoming book (see hereafter), I gave a detailled explanation of the various memory areas the Java VM uses and how these are GCed and also how you can meausre their size (not all, though).
In short you want to use OracleRuntime methods such as
OracleRuntime.getSessionSize(); --> get he current size of Sessionspace
OracleRuntime.getNewspaceSize(); --> get he current size of Newspace
there are other memory areas described in the book

Increasing JVM memory size at runtime

I want to increase the JVM memory size at runtime.
I found out that I can do this with oracle.aurora.vm.OracleRuntime.setMaxMemorySize(...)
Which JAR do I have to put on the classpath to be able to acces OracleRuntime???
What would be the proper implementation to incerase the memory size?

Increase JVM memory size in build.xml?

Hi,
I want to know if it is possible to increase the JVM memory size in the "build.xml" file of my java fx project itself?If so,how to go about it?
Thanks a lot.

I think you can achieve that by specifying <fx:jvmarg>.
For example:
<fx:deploy width="${applet.width}"
               height="${applet.height}"
               embedJNLP="true"
               nativeBundles="all"
                  outdir="${dist.dir}"
               outfile="${application.title}"
               verbose="true">
     
     <fx:platform javafx="2.2+" j2se="7.0">
          <fx:jvmarg value="-Xms64M"/>
          <fx:jvmarg value="-Xmx512M"/>
     </fx:platform>
</fx:deploy>Hope that helps!

How can I control the image size when I export form iphoto, the choice is too limited, I need to send a photo under 3 MB but if I choose high quaulity it is only 1.1 and i need to keep the best quaulity I can. Thanks for help.

How can I control the image size when I export form iphoto, the choice is too limited, I need to send a photo under 3 MB but if I choose high quaulity it is only 1.1 and i need to keep the best quaulity I can. Thanks for help.

Any image can only be as large as the Original. With a program like Photoshop you can UpRes an image and get it to a bigger size, larger files size as well, but the actual quality of the image will be degraded, depending on the UpRes system and the original quality of the image.
iPhoto is not the program to be doing that in and I don't think it even has that option.
So I suspect the image you are trying to send isn't much bigger than what you are getting. You can also try Exporting it from iPhoto to yopur desktop and see what size you end up with. If it is still that 209KB +/- file size then that is the size of the original image.

I have various formatting issues:
a. When I open a msg from my web browser (Cablevision), the font is sooo small I need a magnifier to read it. How can I set the font to a size I can easily read?
b. When I forward msgs, the text gets all distorted and I need to clean it up (some symbols, lots of spaces between words). How can this be fixed?
c. When I want to tell someone about a website, I cannot type the URL in so that all they have to do is click on it. How can this be fixed?
d. When I open messages, the text opens in a small window and covers the "Show Images" button. Why?

The text editor is the text area that you use on the webmail (Yahoo, Hotmail) website to create a new mail.
You can compare that with the ''Post new message'' text area that you use to create a new post on this forum.
Just above the text area that you use to enter the message text there is usually a button bar with buttons that allows some text formatting like Bold and Italic and can also include a button to make a clickable hyperlink.
Check the tooltip of each button by hovering with the mouse over each button.

How can I get size of fetched data size when run a SQL ?

Hi,
When I run a SQL how can I get fetched data size?
regards,

We can get it using some calculations:
1. SQL%ROWCOUNT attribute will fetch you number of rows returned in a SQL statement.
Problem-->Now you need to get the size of 1 row.
Solution-->
Step 1.We can get size of table from dba_segment data dictionary.
Select block_size from dba_segemnts where segment name like '%YOURTABLE%';
Step2 . Get count of rows in your table
Select count(*) from YOUR_TABLE
Step 3.
Get size of 1 row--> Divide result in Step1 by result in Step 2.
Required result--> multiple result in step3 with SQL%ROWCOUNT..
I hope this is what u want.

High resident memory size when creating in-memory db

Capsule summary: an in-memory db created with a cache size of 8 Gb reports a resident size of 2 Gb without any data stored in it.
Details:
We have a need for creating an entirely "in-memory" database, i.e. without a backing file store.The application in question will be writing to and reading from the db frequently, and there is no need to incur the penalty of writing out to disk.
I read the white paper "Writing In-Memory Applications" published by Oracle, and modified our db creation code accordingly. More or less all I did was to allow "open" to be called with a NULL instead of file name.
This seems to work just fine, in that no file is created, and both writing and querying seem to work correctly. However, the resident memory size, even without anything written to the database, seems inordinately high. For example, if I set the cache size to be 8 Gb (the size of physical memory on my Linux FC11 machine), the resident size reported by "top" is 2.0 Gb:
Tasks: 1 total, 0 running, 1 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.7%us, 0.3%sy, 0.0%ni, 98.3%id, 0.6%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 8114752k total, 8054072k used, 60680k free, 45344k buffers
Swap: 11717624k total, 204896k used, 11512728k free, 3977788k cached
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
12827 rao 20 0 2243m 2.0g 9.9m S 0.0 26.0 0:01.53 pypix
Running strace on the process shows that there are three calls to mmap as soon as "open" is called, one of them being responsible for a majority of the allocation.
Is this expected behavior? The documentation explicitly states the following:
"... Note that the size you specify for your cache is actually a maximum size; DB will only use memory as required so if you specify a cache size of 1 GB but your data set is only ever 10 MB in size, then 10 MB is what the DB will use...."
This does not appear to be consistent with what I am seeing.
Any ideas on what I might be doing wrong?
Thanks in advance.

Have you checked what script is causing the issue ? anything from application ? and OLAP things running on this instance ? how many sql instances are running ? anyother application like sharepoint etc runinning on this host ?
Check If your SQL Server instance encounters the following conditions then there is a possibility of
Non-yielding scheduler (SQL Server 2005 and above for the first occurrence. This is equivalent to a 17883 dump in SQL Server 2000.)
Non-yielding resource monitor (SQL server 2005 and above for the first occurrence)
Non-yielding IOCP listener (SQL server 2005 and above for the first occurrence)
Deadlocked Schedulers (SQL server 2005 and above. This is equivalent to a 17884 in SQL Server 2000.)
Exceptions/Assertions
Database Corruption
Latch Timeout
Other conditions (eg: when DUMPTRIGGER is used to generate a dump for a particular exception)

How can I increase the thumbnail size when using Safari to upload an image to a website?

I upload many images to multiple websites and when using Safari to upload these images, the thumbnails are so small I can barely make out what the image is. I can easily figure out how to increase the thumbnail size when viewing them in Finder and set the default to my liking, but I cannot seem to find a way to do this in Safari. The last topic I saw on this was form 2013 and have not seen any update. Is there a way to do this?

Delete all unused, invisible layers.
Sometimes zip compression is better than jpg compression (in the pdf output settings). Zip is lossless, and works better with non gradient colour or no images.
Flattening the image before you save it to pdf can reduce the file size if you are using jpg compression.
Post a preview of your pdf and we can comment further on how to reduce the file size.

HotSpot JVM InternaL Error when running on Mac OS X

I am getting the following error when running a Java process on Mac OS X 10.1.3. This

Sister can't set up Mail on macboook running 10.7.3

I

Sorry about the blank above. Tried to recover a post I started late last night, and it didn't work.
I sent my sister my old MacBook after booting into recovery partition and doing a clean (erased Lion partition first) install. It now runs 10.7.3. As part of the reinstall, had to register it again, and that created an accunt for me. I then added two accounts for my sister and shipped it out to her. BTW, computer had had Apple Care, but that expired over a year ago, and I upgraded the HD and RAM since then.
My sister can't set up her main email account in Mail, even though she carefully input the credentials she has (and which work just fine for her) on her iMac and iOS devices. She even checked with her internet provider to verify that what she was inputting was correct. When she went to Apple online with her problem, it kept telling her that the birthdate she put in was invalid. She even tried using mine, but it didn't work. My questions are:
1)What is causing this?
2) Is there anything I need to do or that she can do from home -or does she have to go to her nearest Apple store's Genius Bar?
Please advise, thanks. Faye
