Uploading about 2GB file into database

Hello,
I want to upload a file of about 2GB size in the database. I am working on Struts framework and with Postgres8 and Oracle8i as database. When I try to upload it through my application it throws "Out of heap memory" error.
Can anyone help me out to solve the problem?
Thanks in advance.

Don't attempt to handle the entire file in memory. Process the data a portion at a time.

File file = new File("myDoc.doc");
FileInputStream fis = new FileInputStream(file);The file name will most likely NOT be hard-coded. I don't think the question surrounding this topic is how to do the insert statement (he/she clearly knows SQL).
HTTP and the web browser take care of the file transfer, but the server stores the file in a temporary location. The question is, "How do I found out that location?" In PHP (I know that doesn't offer much help to you, but ...), that location is held in a variable called $_FILES. From there you can simply copy the file to a location you specify (probably with a user-specified name under a directory specifically for that user).
I hope this is of some help:

Upload .txt file into Database Table

Hi,
I was wondering if someone could please point me in the right direction. I've been looking around the forum but can't find anything to help me achieve the following.
I would like to be able to upload a .txt file using a webpage. Then store the information inside this file into database tables.
eg. contents of mytextfile.txt:
richard
10 anywhere street, anytown, somewhere
111 222 333 444
joe
9 somestreet, elsewhere
999 888 777 666
peter
214 nearby lane, overhere
555 555 555 555
I would like to insert this data into a table.
eg. table name = CONTACTS
userid = primary key (using sequence)
username = (line 1 - richard, joe, peter)
address = (line 2)
phone_no = (line 3)
As you can see the records will appear 1 at a time and will have a blank line between records. Is there anyway for me to upload a file like this and have it placed into tables?
I have seen http://otn.oracle.com/products/database/htmldb/howtos/howto_file_upload.html but this seems to be for uploading a whole file and downloading the same file, rather than extracting data from the file.
I hope I have managed to explain my problem.
Many thanks,
Richard.

Richard,
HTML DB allows you to upload CSV files via the Data Workshop. That data would then be parsed and inserted into a specific table. Alternatively, if you have your data in an Excel spreadsheet, and it is less than 32k, you can copy & paste the data directly into HTML DB's Data Workshop, which will then parse and import it into the Oracle database.
The one obstacle you may have to overcome is converting your data from the format you outlined to CSV format. Specifically, you would have to make this:
richard
10 anywhere street, anytown, somewhere
111 222 333 444
Look something like this:
"richard","10 anywhere street, anytown, somewhere","111 222 333 444"
Hope this helps,

Upload an XML file into the Internal table

Hi Guys,
I want to know, how to upload an xml file into the Internal table through ABAP programming

you just wanted to load the xml file into internal table (as a table of binary strings)or load the xml data mapped to itab row columns
for the first one you can simply use gui_upload
and for the second one you need to load the xml file using gui_upload and use XLST program to transform into an itab

How to upload an XML file into another system

Hi friends,
I have a requirement where I need to upload an XML file into one system
which has been downloaded using another system.
I have tried using the method ' cl_gui_frontend_services=>gui_upload'
to upload the file but it is going for dump.
I have used the method ' w_xml->import_from_file' also,
but it is also going for dump ,because both methods are using the same FM
' GUI_UPLOAD'.
Can any one suggest on this.
Regards,
Bhargavi.D

"Here is the Explaination for uploading the XML   Format file to sap   " through ABAP Program ....
1. Basically you simply have to convert the XML file into the proper IDoc format. There are many ways to achieve this. One solution would be to convert it externally to SAP, e.g. via VB Script or with an XSLT transformation. Or you use the built in SAP functions for importing an IDoc from an XML stream.
2. Uploading a file is either done via GUI_UPLOAD or via the usual way of reading a file from the application server (Open dataset. Read dataset) But what do you mean by "send to external system"? Do you want to convert an IDoc into XML? Then you simply define an XML port with WE21 to send the IDoc out.
Here is an example of code that loads an XML from file and posts it as an IDoc. Please keep in mind that the XML has to be in its canonical format as described in the interface repository: ifr.sap.com (choose the template of the desired IDoc from there as an example).
data: data_tab type table of char1024.
data: XML_STREAM type string.

Upload Attachements(Doc File) into SAPand Read The same in BADI

Hi All,
I am Nagesh, and presently working on a BADI(NOTIF_EVENT_POST) for sending emails when a new Notification is created through QM01 Transaction Code, and its working very very fine. But now an additional requirement has come up, where i need to upload an Standard Format Word Document into SAP and then attach this file to the Mail to which the converted PDF Smartform file has been attached and then send both files in single mail to concerned Vendor. So I tried to upload the .Doc file into SAP by using OAER TCode with following Parameters
Class name              :            PICTURES
Class type               :            OT
Object key               :            CAPA.
I exactly dont know whether this is the right format or not, please help me, if this is possible or not.
And also I uploaded the same doc file from application server to Presentation Server using Tcode CG3Z, to a ditectory which exists in SAP (Checked in AL11 Tcode). So the nhow to read that complete file to send the same as attachemnts without making any changes .
Regards,
Nagesh Kumar.

1. Create a conrtol file in your disc(with notepad) ex

LOAD DATA
INFILE='C:\Testcsv.csv'
into table test_table
FIELDS TERMINATED BY ','
TRAILING NULL COLS
(ID,COL1,COL2,COL3)
The table descrption is
scott@ORCL> desc test_table;
Name Null? Type
ID NUMBER
COL1 VARCHAR2(10)
COL2 VARCHAR2(10)

2 .Create a file testcsv.csv from your excel file you want to load with " save as" csv comma seperated value
in your hard disc c:\
3. in dos command mode write
C:\>sqlldr scott/tiger control=c:\testcsv.ctl log=c:\testcsv.log
