How to split big file?
Hi, folks,
I have a big binary file (around 400M). How can I split it to several small files? If I just use the file read subvi in labview, it will show "not enough memory" error. How can I solve this problem?
Any help will be appreciated!

This is because you are attempting to read the entire file at once.
File I/O allows you to read anywhere from one byte to the entire file.
I don't know what is in your file, but the read characters from file has
an input for how many characters. Or you can use the more advanced File
Open followed by File Read with specific types wired up.
Either way, determine how you will break it up. 40 10M files, 10 40M
files, etc. Then make a loop where you create the new file, read the
data from the old large file, then write it to the new file, then clos
e
the new file and go to the next iteration of the loop.

Hi Ali,
If the PDF file you're starting with is larger than 100MB, ExportPDF won't be able to convert it.
To convert a file of that size and to create separate files, you'll need Adobe Acrobat. You'd need Acrobat to divide the file into smaller chunks for ExportPDF anyhow, so Acrobat is probably the best solution for you. You can learn more about Acrobat here: http://www.adobe.com/products/acrobat.html

Hi all,
I have a big text file (about 140MB) containing data I need to read and save (after analysis) to a new file.
The text file contains 4 columns of data (so each row has 4 values to read).
When I try to read all the file at once I get a "Memory full" error messags.
I tried to read only a certain number of lines each time and then write it to the new file. This is done using the loop in the attached picture (this is just a portion of the code). The loop is repeated as many times as needed.
The problem is that for such big files this method is very slow and If I try to increase the number of lines to read each time, I still see the PC free memory decending slowly at the performance window....
Does anybody have a better idea how to implement this kind of task?
Thanks,
Mentos.

Read a file portion.png 13 KBHi Mark & Yamaeda,
I made some tests and came up with 2 diffrenet aproaches - see vis & example data file attached.
The Read lines aproach.vi reads a chunk with a specified number of lines, parses it and then saves the chunk to a new file.
This worked more or less OK, depending on the dely. However in reality I'll need to write the 2 first columns to the file and only after that the 3rd and 4th columns. So I think I'll need to read the file 2 times - 1st time take first 2 columns and save to file, and then repeat the loop and take the 2 other columns and save them...
Regarding the free memory: I see it drops a bit during the run and it goes up again once I run the vi another time.
The Read bytes approach reads a specified number of bytes in each chunk until it finishes reading all the file. Only then it saves the chunks to the new file. No parsing is done here (just for the example), just reading & writing to see if the free memory stays the same.
I used 2 methods for saving - With string subset function and replace substring function.
When using replace substring (disabled part) the free memory was 100% stable, but it worked very slow.
When using the string subset function the data was saved VERY fast but some free memory was consumed.
The reading part also consumed some free memory. The rate of which depended on the dely I put.
Which method looks better?
What do you recommand changing?

How to split a file by using Native Format Builder?
Hi all,
Please help me with this issue.
In this project we need to split a file to save in the db.
Following is the sample code and I would like to split this from 'BOH--------------' to 'BOT---------------' (as in BOLD)
But as you can see sometimes 'BOT' line comes up multiple times so I need to skip few 'BOT's until I meet new 'BOH' line.
I guess I have to use complex type in Native Format Builder, but I'm not sure how to..
Please help me with this situation.
Thanks in advance.

Edited by: 964067 on Oct 14, 2012 11:26 PMHi,
Firstly please ensure that the file that you are reading is bound to have a format of some sort.
I will relate this to one of the requirement we did it in previous projects.
We have a requirement to read a csv file coming in:
1) It will be having records for Header (ODH) and Detail (ODL)
2) The Header and Detail records will be repeated 'N' number of times in the input file.
The schema we used it something as below to poll the CSV file:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:nxsd="http://xmlns.oracle.com/pcbpel/nxsd"
xmlns:tns="http://TargetNamespace.com/ReadCSV" targetNamespace="http://TargetNamespace.com/ReadCSV"
elementFormDefault="qualified" attributeFormDefault="unqualified" nxsd:parseBom="true"
nxsd:version="NXSD" nxsd:stream="chars" nxsd:encoding="US-ASCII">
<xsd:element name="Package">
<xsd:complexType>
<xsd:choice minOccurs="1" maxOccurs="unbounded" nxsd:choiceCondition="terminated" nxsd:terminatedBy=",">
<xsd:element name="Header" nxsd:conditionValue="BOH">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="RecordAction" type="xsd:string" minOccurs="0" nxsd:style="terminated"
nxsd:terminatedBy="," nxsd:quotedBy="""/>
<xsd:element name="VisitType" type="xsd:string" minOccurs="0" nxsd:style="terminated"
nxsd:terminatedBy="," nxsd:quotedBy="""/>
<xsd:element name="OrderAction" type="xsd:string" minOccurs="0" nxsd:style="terminated"
nxsd:terminatedBy="," nxsd:quotedBy="""/>
<xsd:element name="Route" type="xsd:int" minOccurs="0" nxsd:style="terminated"
nxsd:terminatedBy="${eol}" nxsd:quotedBy="""/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:element name="Lines" nxsd:conditionValue="BOD">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="RecordAction" type="xsd:string" minOccurs="0" nxsd:style="terminated"
nxsd:terminatedBy="," nxsd:quotedBy="""/>
<xsd:element name="OrderCode" type="xsd:string" minOccurs="0" nxsd:style="terminated"
nxsd:terminatedBy="," nxsd:quotedBy="""/>
<xsd:element name="ShippingUnitNumber" type="xsd:int" minOccurs="0" nxsd:style="terminated"
nxsd:terminatedBy="," nxsd:quotedBy="""/>
<xsd:element name="ProdOptDesc" type="xsd:string" minOccurs="0" nxsd:style="terminated"
nxsd:terminatedBy="${eol}" nxsd:quotedBy="""/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:choice>
</xsd:complexType>
</xsd:element>
</xsd:schema>
So the approach we followed is as below:
1) Design two DB tables. One to put the header records in Header table
2) Put the detail records in Trailer table.
3) Poll from these two tables to trigger next business requirements.
Hope this helps.
Thanks,
Deepak. -
How to Split Large Files?
I've got a large 4GB+ file that I want to transfer onto my USB stick, but because it's a FAT32 format, it won't allow transferring over 4GBs.
How can I split the file into two 2GB files then reattach them after unzipping?Good observations but maybe I miss the part where the OP says imovie is involved.
I used Split&Concat when I was transferring files from a PC to a Mac when I had .mov files that were larger than the flash drive capacity. The flash drive was FAT format so this post specifically rang a bell. I am trying to remember what I used on the PC side but Split&Concat used the same file splitting format which was cross-platform. -
How effective splitting one file in to multiple in PI
Hi Forum,
Is it possible to split one file in to 20 or more using PI.
If yes,how effective it is.Yes. And there are various ways for doing this.
1. In the adapter engine while picking the flat file using option "Recordset per Message"
2. Using multi-mapping message split.
3. Using BPM loops.
The effectiveness would depend upon the size of message and no of records it contain. e.g. if the size is small, say only 20 records, then splitting the message in 20 parts would not be a good option. But if the size is too large with say thousands of messages, then splitting would turn out to be effective.

How to exchange big files between mac users through the internet?
How can we send and receive big files between Mac users (apart from Dropbox) ?
If you aren't on the same local network (which I assume you aren't), then the easiest solution is to use Google.
If you simply google "sending large files" you will get hundreds of suggestions/applications.
Ie Dropbox, Google, YouSendIt, FTP, etc -
How to split a file into two small file
Hi All,
I want to raed a file from FTP server.Then i have to split a file into two small file.File format look like this.
R01!service_order!item_guid!resource_guid!assignment_guid
R02!Service_order!product_id!product_discription!quantity
R02!Service_order!product_id!product_discription!quantity
R02!Service_order!product_id!product_discription!quantity
i want split file into 2 file,according to header and item details.one table containt header information (label R01) and second table containt (label R02).
can anybody help me for this.how can i split into 2 file.
Thanks
Vishwas SahuCreate 2 internal tables. sat it_header, it_detail
Check for 1st 3 characters and if it is R01 then send it into it_header and if it comes out to be R02 then send it to it_detail.
Once done... You can either attach these tables into mail as two seperate files
Or you can download each internal table using GUI_DOWNLOAD.
Hope this helps!!

How to split PDF file by pages
Is there any programming way to split PDF into pages, say one PDF file per page or specify page range to split PDF file?
Thanks for your help.Yes it does. It disassembles pdf1 by extracting pages 1-3 and disassembles pdf2 by extracting pages 4-5. Then re-assembles the two subsets into a new PDF.
You could extract page1 from pdf1 only and create a pdf, then page2 of pdf1 into a different PDF using something similar to:
<?xml version="1.0" encoding="UTF-8"?>
<DDX xmlns="http://ns.adobe.com/DDX/1.0/">
<PDF result="Final.pdf">
<PDF source="PDF1.pdf" pages="1"/>
</PDF>
<PDF result="Final2.pdf">
<PDF source="PDF1.pdf" pages="2"/>
</PDF>
</DDX>
You can also use the PDFFromBookmarks tag to generate a new document for each level 1 bookmark created in a PDF.
<PDFsFromBookmarks prefix="stmt">
<PDF source="doc1.pdf"/>
</PDFsFromBookmarks>

How to split big xml-messages with file inbound adapter
Hello,
we have big xml-messages in our filesystem, which are processed by XI 3.0 (SP11). We are using the file inbound adapter. Now we want to split these big xml-message into some smaller messages.
Exist there a corresponding function to the "xml.recordsetsPerMessage" which is working with xml-files?
Thanks!
Regards
StefanHi,
maybe you can split the message in the BPM
with 1:N mapping?
Process Integration (PI) & SOA Middleware
I don't think anythink like "recordsetsPerMessage" is possible for xml messages

How to handle Big FIles in SAP PI Sender file adapter
Hi all ,
I have developed a interface , where it is File to Proxy, it is fine when i do with small and normal files
The structure contain one Header unbounded detail and one Trailer, how to handle when the file size is more than 40 MB
Thanking you
SridharHi Sridhar Gautham,
We can set a limit on the request body message length that can be accepted by the HTTP Provider Service on the Java dispatcher. The system controls this limit by inspecting the Content-Length header of the request or monitoring the chunked request body (in case chunked encoding is applied to the message). If the value of the Content-Length header exceeds the maximum request body length, then the HTTP Provider Service will reject the request with a 413 u201CRequest Entity Too Largeu201D error response. You can limit the length of the request body using the tting MaxRequestContentLength property of the HTTP Provider Service running on the Java dispatcher. By default, the maximum permitted value is 131072 KB (or 128MB).You can configure the MaxRequestContentLength property using the Visual Administrator tool. Proceed as follows:
1. Go to the Properties tab of the HTTP Provider Service running on the dispatcher.
2. Choose MaxRequestContentLength property and enter a value in the Value field. The length is specified in KB.
3. Choose Update to add it to the list of properties.
4. To apply these changes, choose (Save Properties).
The value of the parameter MaxRequestContentLength has to be set to a high value.
The Visual administartor tool may be accessed using this link

In short ICM parameters to reset values for this case are
icm/HTTP/max_request_size_KB
icm/server_port_ TIMEOUT
rdisp/max_wprun_time
zttp/max_memreq_MB
Please look into this thread to know more about ICM parameters

Second solution is that you must split the source file, so that each file is less than 5MB in size, then PI would not cause problem for file size between 1MB-5MB. you can insert header and trailer for individual smaller file obtained after split. All this can be done using scripts or conventional programing provided individual records within file are independent of each other. Finally you have to rename each new file created and put them in PI folder in sequential manner. All this can be achieved by simple shell script/batch file, a C code or java code. If you are going for a C or Java code you need a script to call them from PI communication channel parameter "run operating system command before message processing".

For No, Name, City Map Directly.
In the example, I've given 5 records to split. If you want 50 records to split, then instead of 5 give 50 in the constant.

How to split video files into clips
please help this noob. i have adobe master collection cs3 and i'm totally lost as to how i can take a large video file and split it into various clips... example being a 20 minute fireworks display and i want to split that movie into a few dozen clips of specific fire works events. what package do i use and how might i go about setting the various start and finish markers and then export those chosen clips.
any help would be greatly appreciated.
thanks much
michaelExporting segments out one at a time is hardly rocket surgery.
At the top of the timeline is a movable bar called the "Work Area Bar". You can set the in and out points of this bar over the area you wish to export, go to "File/Export/Movie" and make sure you have "Work Area Bar" selected rather than "Entire Sequence". Export to the same project settings you're working with. Repeat for each section. -
How to split Big Applications over two HDs for optimal performance?
Assuming both situations are using a 80gb Raptor [drive #1] and 500gb 7K500 [drive #2]:
would it be better to ....
a) install both the OS and applications on the raptor, while using the 500gb as the scratch?
b) install the OS on the raptor, and have all applications installed on the 500gb drive and have the scratch on the same drive?
how about for applications such as Final Cut Pro, which has a lot of associating files (and sound bites in the case of Audio Programs) ..... what would be the best way to split this up over those two drives? (for optimal CPU/disk performance)
any help would be MUCH appreciated!! THANKSMethinks you're overworrying the problem. You should be able to install Tiger and most applications into something less than 30 GB. Everything I have, iLife, Office 2004, Quicken, Toast, TurboTax, and a slew more take up less than 10 GB. Install everything you have on the Raptor, then partition the 500 GB into two or four partitions and use them to store your data, music, movie, and photo files. Link them to your User folder's like named folders. That should satisfy your needs.

Hi , I'm new in this area of Java and I'm lost. How can I split a MIDI song in different song, each one had a differnet track of the MIDI file? Thanks
Hi,
MIDI files aren't necessarily music files they're data files. If you plan on doing a lot of work with midi's i suggest you use an API called JFugue (www.jfugue.org). Using this you can parse the file to a string getting something like this (C5q, D5q) meaning note C in the 5th octave to be played for a quarter of a note and D the same. Getting this as a string makes it very easy to split and manipulate.
Hope this helps,
Jenn
