Exporting large excel file exception

Hello-
I am using Jasper reports within a j2ee application to generate an excel file, and this file is written on the reponse outputstream. It is deployed as a web application on Oracle application server 10g
When the generated xls file is large like 2 Mb or more, Oracle application server throws ServletException and sometimes NullpointerException.
The same application runs smoothly on the IBM Webshpere test server embedded on websphere application developer.
I tried to increase the reponse buffer size for AS10g but the problem is still there.
Could anyone help in this?
Thanks

Hi Jason,
Unfortunately, Xcelsius is not designed to handle the large volume of embedded data that you have described. There are basically 2 approaches to resolve your issue:
1) Try to aggregate the data and simplify the lookups, to reduce the total number of cells until Xcelsius is able to process it;
2) Store the large volume of data in an external data source and retrieve only the necessary subset of data via one of Xcelsius's external connectivity options including web services or XML etc.
Also, with 15 tabs, depending on the number of components you have within each tab panel, you may also be pushing the limit of how many total components Xcelsius can handle. However, based on your comments, I would say the real issue is the 8MB Excel file, a size which Xcelsius simply cannot handle.
Regards,
Mustafa.

There's no control over per-cell formatting for Excel exports.

Large excel files won't combine to pdf in Acrobat X or XI

I have large Excel files (0.3 to 1.2 MB) that I used to combine into a single pdf. It will only work now on Excel files smaller than 1MB. This was working a few weeks ago. What happened? I have tried on computers that have both Acrobat X and XI (we have both scattered around our building).
Any ideas? Thanks.

FileOpen is a security add-on, which is needed to open some files. Not a part of Adobe software. Maybe you need to upgrade or report it: http://www.fileopen.com/

I need to sort very large Excel files and perform other operations. How much faster would this be on a MacPro rather than my MacBook Pro i7, 2.6, 15R?

I am a scientist and run my own business. Money is tight. I have some very large Excel files (~200MB) that I need to sort and perform logic operations on. I currently use a MacBookPro (i7 core, 2.6GHz, 16GB 1600 MHz DDR3) and I am thinking about buying a multicore MacPro. Some of the operations take half an hour to perform. How much faster should I expect these operations to happen on a new MacPro? Is there a significant speed advantage in the 6 core vs 4 core? Practically speaking, what are the features I should look at and what is the speed bump I should expect if I go to 32GB or 64GB? Related to this I am using a 32 bit version of Excel. Is there a 64 bit spreadsheet that I can us on a Mac that has no limit on column and row size?

Grant Bennet-Alder,
It’s funny you mentioned using Activity Monitor. I use it all the time to watch when a computation cycle is finished so I can avoid a crash. I keep it up in the corner of my screen while I respond to email or work on a grant. Typically the %CPU will hang at ~100% (sometimes even saying the application is not responding in red) but will almost always complete the cycle if I let it go for 30 minutes or so. As long as I leave Excel alone while it is working it will not crash. I had not thought of using the Activity Monitor as you suggested. Also I did not realize using a 32 bit application limited me to 4GB of memory for each application. That is clearly a problem for this kind of work. Is there any work around for this? It seems like a 64-bit spreadsheet would help. I would love to use the new 64 bit Numbers but the current version limits the number of rows and columns. I tried it out on my MacBook Pro but my files don’t fit.
The hatter,
This may be the solution for me. I’m OK with assembling the unit you described (I’ve even etched my own boards) but feel very bad about needing to step away from Apple products. When I started computing this was the sort of thing computers were designed to do. Is there any native 64-bit spreadsheet that allows unlimited rows/columns, which will run on an Apple? Excel is only 64-bit on their machines.
Many thanks to both of you for your quick and on point answers!

Bitmap is not exporting to excel file

Any kind help appreciated.
I have added a bitmap image in my workbook but when i am exporting it into excel or html ,only text part of the title is exporting into excel file .
The bitmap is only visible in discoverer workbook ,after exporting to excel or html, it disappears,
i am using oracle 9i discoverer version 9.0.2.0
thanks,

Hi,
Bitmaps in the workbook titles are not exported. I guess it was just too difficult to do when they added bitmaps into the titles.

I am having trouble opening a large Excel file (xlsx) on my iPad3

Do I need to purchase an app to be able to open this large Excel file?

Of course. No computer will open a file without an appropriate program to do so. Search the App Store for "spreadsheets" to get an idea of what software is available. Aples own "Numbers" might be considered, or "QuickOffice" or several others,

Hi,
i have the same issue now where i need to populate the xport file name as report name. can you send me your solution please.

Can i export an excel file to my I-Cal & if so how?

Hi. I have a large amount of data/dates in an excel file and I would like to easily export these into my I-Cal. Please advise.

But if it's a big album, be sure to create a new folder on the desktop first, to export them into. Having hundreds of individual photos on your desktop will slow your computer to a crawl.

Export to excel file problem

When I export my Crystal report to excel file (97-2000)
it does not show the Boxes and lines in excel file.
I am using CR 11 and MS Office 2003
please guide me how to solve this problem
Edited by: mian ghous on Feb 10, 2009 1:59 PM

But, DUDE, it IS possible using borders! Each of the border options has a formula field that you can code to tell Crystal in effect "on this line of the report, I want xxx borders".
Let's start with the easiest example: Say you want the line to go around the column heading (full box). then lines down each side of the column until the end, then for the the subtotal you want lines on three sides (all but top). Set all four borders for the heading field to Single, set the right and left borders for the data field to Single, and set all but the top border for the subtotal field to Single.
To expand this, let's say there is no subtotal, and you want the last value in the field to have a bottom border. Set the header and data field borders as above, except for the bottom border of the data field, use the following formula (basic syntax):
if {field} = NextValue({field}) then
formula = crNoLine
else
formula = crSingleLine
end if
If you want the line across the top of the data field on the first detail row (i.e., not around the header), use the same logic as above, except using PreviousValue().
HTH,
Carl

Error message exporting large picture file from Aperture 3.5

Recently I took a large panaramic comprised of 165 pictures using Gigapan Epic Pro and stitched together using software provided with Gigapan. I exported the stitched file into Aperture to perform final edits. When I go to export the final version I keep getting an error message. The file size will be approximately 2.0 GB. I've been able to export a 0.7 GB file without problems (it did take several minutes). I have a late 2009 27" iMac with 3.3 GHZ Intel Core 2 Duo processor and 16 GB memory. Any suggestions? Not sure if this is an Aperture problem or if my system is not up to the task. Below is the error mesage I receive. Thanks for your assistance.

Testing: Exporting a large TIFF - the original is 24512 × 23016 (564,2 MP), 1.05 GB
The exported file that I am seeing on my Desktop after 10 minutes, is showing this in the Preview:
But after exporting there was no message at - neither an error message nor the usual alert when finished "Export 1 version completed - Reveal ...".
So, I am not yet conviced that the export went well, but Aperture can export gigantic TIFFs.
What is the file format you have been using? My test was done with TIFF, 16 bit.

Export to Excel - File Name WAD 7.0

Hi All,
I am using Export to Excel Functionality with WAD 7.0 to export the report to excel format.
I have used button web item, with an excel picture above it. The functionality works fine.
But while exporting the name of excel file shown is WAD 7.0 name.
ex. My WAD 7.0 name is IFIOP_C07_W700, the excel file also gets saved in this name.
I want it to be made customizable.
Can you throw some pointers.
Thanks,

Room Data not getting exported to excel file

Hello,
I am facing a small issue regarding collaboration rooms.
I created some Rooms and Created few Tasks in each room. I tried to export the task details in a excel file. For most of the rooms it is working fine but for few rooms either data is not getting exported or some data is missing in the generated excel file.I am working on EP 7.0 and all the rooms are created from the same user.
What could be the possible reason for such a behaviour ? Kindly Help me with this.

i believe you can use GUI_DOWNLOAD simply for this purpose.
CALL FUNCTION 'GUI_DOWNLOAD'
EXPORTING
    FILENAME                        = 'c:\abc.xls'
   FILETYPE                        = 'ASC'
   WRITE_FIELD_SEPARATOR           = 'X'
TABLES
    DATA_TAB                        = ITAB
it will work, i believe.

Another question about import/export to excel file?

Hi, I need to know urgently if it's possible to import/export excel files from/to JSP with unpredicted number of fields each row. For example, row 1 in the excel file can have 5 columns of data, row 2 has 3 columns of data, etc...
Does reading from excel file in JSP require that we know beforehand how many columns there are and what each column represent?

It might have but this is not a problem, if you programmatically break it up in pieces.
Have a look at https://forums.oracle.com/message/9748097#9748097
The method demonstrates how to dump/write a CSV in binary format to disk.
I used it to dump/write files way bigger than 10++ MB in size...
