Storing a ZIP file to the database

I have to store a zip file to the database. I used ZipOutputStream to compress the data into the Zip format and then insert into the Database.
This is what i am doing:
java.sql.PreparedStatement pst = null;
GZIPOutputStream out_stream = null;
try
out_stream =
new GZIPOutputStream( new ByteArrayOutputStream( reqdata.length() ) );
FileOutputStream fstr = new FileOutputStream( "file1" );
ObjectOutputStream obst = new ObjectOutputStream( fstr );
obst.writeObject( out_stream );
obst.close();
FileInputStream in = new FileInputStream( "file1");
ObjectInputStream in_stream = new ObjectInputStream(in);
pst.setBinaryStream( 3, in_stream, reqdata.length() );
in_stream.close();
catch( Exception e )
reqdata is the data that i want to store, which i m reading from a file at present.
It fails at obst.writeObject( out_stream ); coz the GZIPOutputStream is not serializable.
This data(ZIP file) has to be again read from the database.
Can someone please help me with this or let me know if there is any other way to do the same
Thanks in advance

Just drop the business with the ObjectOutputStream and ObjectInputStream. They would be unnecessary and time-wasting even if they did work.

How to get up and running with WebUtil 1.06 included with Oracle Developer Suite 10.1.2.0.2 on a win32 platform
Solution
Assuming a fresh "Complete" install of Oracle Developer Suite 10.1.2.0.2,
here are steps to get a small test form running, using WebUtil 1.06.
Note: [OraHome] is used as an alias for your real oDS ORACLE_HOME.
Feel free to copy this note to a text editor, and do a global find/replace on
[OraHome] with your actual value (no trailing slash). Then it is easy to
copy/paste actual commands to be executed from the note copy.
1) Download http://prdownloads.sourceforge.net/jacob-project/jacob_18.zip
and extract to a temporary staging area. Do not attempt to use 1.7 or 1.9.
2) Copy or move jacob.jar and jacob.dll
[JacobStage] is the folder where you extracted Jacob, and will end in ...\jacob_18
     cd [JacobStage]
     copy jacob.jar [OraHome]\forms\java\.
     copy jacob.dll [OraHome]\forms\webutil\.
The Jacob staging area is no longer needed, and may be deleted.
3) Sign frmwebutil.jar and jacob.jar
Open a DOS command prompt.
Add [OraHome]\jdk\bin to the PATH:
     set PATH=[OraHome]\jdk\bin;%PATH%
Sign the files, and check the output for success:
     [OraHome]\forms\webutil\sign_webutil [OraHome]\forms\java\frmwebutil.jar
     [OraHome]\forms\webutil\sign_webutil [OraHome]\forms\java\jacob.jar
4) If you already have a schema in your RDBMS which contains the WebUtil stored code,
you may skip this step. Otherwise,
Create a schema to hold the WebUtil stored code, and privileges needed to
connect and create a stored package. Schema name "WEBUTIL" is recommended
for no reason other than consistency over the user base.
Open [OraHome]\forms\create_webutil_db.sql in a text editor, and delete or comment
out the EXIT statement, to be able to see whether the objects were created witout
errors.
Start SQL*Plus as SYSTEM, and issue:
     CREATE USER webutil IDENTIFIED BY [password]
     DEFAULT TABLESPACE users
     TEMPORARY TABLESPACE temp;
     GRANT CONNECT, CREATE PROCEDURE, CREATE PUBLIC SYNONYM TO webutil;
     CONNECT webutil/[password]@[connectstring]
     @[OraHome]\forms\create_webutil_db.sql
     -- Inspect SQL*Plus output for errors, and then
     CREATE PUBLIC SYNONYM webutil_db FOR webutil.webutil_db;
Reconnect as SYSTEM, and issue:
     grant execute on webutil_db to public;
5) Modify [OraHome]\forms\server\default.env, and append [OraHome]\jdk\jre\lib\rt.jar
to the CLASSPATH entry.
6) Start the OC4J instance
7) Start Forms Builder and connect to a schema in the RDBMS used in step (4).
Open webutil.pll, do a "Compile ALL" (shift-Control-K), and generate to PLX (Control-T).
It is important to generate the PLX, to avoid the FRM-40039 discussed in
Note 303682.1
If the PLX is not generated, the Webutil.pll library would have to be attached with
full path information to all forms wishing to use WebUtil. This is NOT recommended.
8) Create a new FMB.
Open webutil.olb, and Subclass (not Copy) the Webutil object to the form.
There is no need to Subclass the WebutilConfig object.
Attach the Webutil.pll Library, and remove the path.
Add an ON-LOGON trigger with the code
         NULL;
to avoid having to connect to an RDBMS (optional).
Create a new button on a new canvas, with the code
         show_webutil_information (TRUE);
in a WHEN-BUTTON-PRESSED trigger.
Compile the FMB to FMX, after doing a Compile-All (Shift-Control-K).
9) Under Edit->Preferences->Runtime in Forms Builder, click on "Reset to Default" if
the "Application Server URL" is empty.
Then append "?config=webutil" at the end, so you end up with a URL of the form
      http://server:port/forms/frmservlet?config=webutil
10) Run your form.sarah

How to import an .csv file into the database?

and can we code the program in JSP to import the.csv file into the database.

It is better to use Java class to read the CSV file and store the contents in the database.
You can use JSP to upload the CSV file to the server if you want, but don't use it to perform database operations.
JSPs are good for displaying information on the front-end, and for displaying HTML forms, there are other technologies more suitable for the middle layer, back end and the database layer.
So break you application into
1) Front end - JSPs to display input html forms and to display data retrieved from the database.
2) Middle layer - Servlets and JavaBeans to interact with JSPs. The code that reads the CSV file to parse it's contents should be a Java Class in the middle layer. It makes use of Java File I/O
3) Database layer - Connects to the database using JDBC (Java Database Connectivity), and then writes to the database with SQL insert statements.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Keeping the above concepts in mind, first build a simple JSP and get it to work,
then research on Google , for Java File I/O , discover how to read a file,
Then search on how to readh a CSV file using Java.
After researching you should be able to read the CSV file line by line and store each line inside a Collection.
Then research on Google, on how to write to the database using JDBC
Write a simple program that inserts something to a dummy table in the database.
Then, read the data stored in the Collection, and write insert statements for each records in the collection.

Large files are usually stored as binary large objects (BLOBS.) I think MS Access calls these Memo fields.

Hello Anybody, I have a question. Can any of you please suggest me how to make an xml file from the database table with all the rows? Note:- I am having the XSD Schema file and the resulted XML file should be in that XSD format only.

Hello Anybody, I have a question. Can any of you please suggest me how to make an xml file from the database table with all the records?

The Oracle documentation has a good overview of the options available
Generating XML Data from the Database
Without knowing your version, I just picked 11.2, so you made need to look for that chapter in the documentation for your version to find applicable information.
You can also find some information in XML DB FAQ

Compress/zip files from the command line in Windows 7?

In Windows 7 is there a native way to compress or zip files from the command line? I'd like to do it without installing any third-party utilities such as 7Zip.

I fully agree that Compact is not the answer. There are additional concerns with the Compact command. It enables disk compression which is a total no-no. Very bad! It makes your computer very slow and is quite difficult to undo. The only time anyone should
use this command is when they're removing disk compression because someone turned it on to save space. Turning this off has to be done by booting into the recovery console, if my memory serves me correctly, and it's a real nuisance. So
definitely no to the Compact command.
If you wanted to compress files before sending them to another drive, or over a network, or by email, then Compact wouldn't actually help at all because the files have to get uncompressed whenever they're accessed, especially before sending them anywhere.
When I say accessed, I mean that just looking at a file triggers the OS to decompress it in the background and present you with an uncompressed version of it then letting you change it and recompressing it again for storage every single time you access the
file, which is why your machine gets slower. If you have folders or files that have blue text instead of black, then you've probably already made this mistake.
I would also like to know if there is a built-in command for zipping files/directories, or, if there isn't such a thing built into Windows, then I would like to know if this is feature is accessible through Visual Studio, which would be just as good as having
a command-line program for those of us that do a bit of programming.
If anyone knows if MS provides such a feature, either by command-line or through an API, then I'd love to hear about it. Good luck to those of you that have disk compression turn on.

What is the max size of a zip file with the JDK1.5 ?

Hello everybody,
I'm a french student and for a project, I need to create a zip file, but I don't know in advance the number and the size of files to include in my zip.
I wish to know if someone have the answer to my question : what is the max size of a zip file with the JDK1.5 ? I believe that with the JDK1.3, the limit size of a zip was about 2Go, wasn't ?
Thank you for all answer !
Good day !
PS : sorry for my very poor english ;-)

Here is all I have found for the moment :
...Okay, what about my suggestion of creating your own 10GB file?
Try this:import java.io.File;
import java.io.RandomAccessFile;
import java.nio.ByteBuffer;
import java.nio.channels.FileChannel;
import java.util.Random;
class Main {
    public static void main(String[] args) {
        long start = System.currentTimeMillis();
        int mbs = 1024;
        writeFile("E:/Temp/data/1GB.dat", mbs);
        long end = System.currentTimeMillis();
        System.out.println("Done writing "+mbs+" MB's to disk in "+
                ((end-start)/1000)+" seconds.");
    private static void writeFile(String fileName, int numMegaBytes) {
        try {
            int numBytes = numMegaBytes*1024*1024;
            File file = new File(fileName);
            FileChannel rwChannel =
                    new RandomAccessFile(file, "rw").getChannel();
            ByteBuffer buffer = rwChannel.map(
                    FileChannel.MapMode.READ_WRITE, 0, numBytes);
            Random rand = new Random();
            for(int i = 1; i <= numMegaBytes; i++) {
                for(int j = 1; j <= 1024; j++) {
                    byte[] bytes = new byte[1024];
                    rand.nextBytes(bytes);
                    buffer.put(bytes);
            rwChannel.close();
        } catch(Exception e) {
            e.printStackTrace();
}On my machine it took me 43 seconds to create a 1GB file, so it shouldn't take too long to create your own 10GB. Then try zipping that file.
Good luck.

Which is better? store files in the database or directly on the O.S.?

Hi,
i´m developing an application to manager files. which is better? store files in the database or directly on the O.S.? If i decide to store on database, i will use the BLOB data type but i have a doubt...the BLOB data type occupies the same space on database regardless of file size? there is another data type better?
Tks,
Fernando.

Socket blocking on read operation while uploading zip file to the server

I am trying to upload a zip file to the server
Client thread creates the zip file ( of the modified files) and it even completes writing the data to the socket stream.
Now if the server thread tries to read the same data from the stream, it blocks on read operation.
While downloding the zip file from the server works fine.
Thanks in advance

You can use the URL object to upload it as multipart/form-data.

Can change the size of the redolog files while the database is running.

How the size of the redolog files will hurt your database performance ?
Can change the size of the redolog files while the database is running in oracle 9i. ?
What will be its impact on the standby database ?
Thanks in advance.

redo logs that are too small can cause waits on the switches for heavily utilized systems. logs that are too large are a pain the a$$ during recovery. check v$loghist to see how often switches occur - an average of 20 minutes is good; if you have many switches happening back-to-back, that's a bad sign.
you can change the sizes while the db is up. choose a redo group that is INACTIVE, drop it, delete the files, and recreate it with larger files. then force a switch ("alter system switch logfile;"), and do another inactive group. I actually prefer to do as many switches as necessary to make the new group active so I can verify that I didn't screw up before dropping the next group.
not sure of impact on standby database.

Save a report 6i PDF file onto the database server

Hello Experts,
I have a requirement, whereby I need to generate a PDF report and then send that report via Email. The problem I have is my email procedure is looking for the file which is in the directory on the server where the database is stored, While the PDF is generated on the local machine. Im using reports 6i.
I know in reports 10g the file is generated on the report server itself but Im afraid same is not the case with reports 6i.
The other problem is the local machine does not have the access to the directories on the server. I tried to change the directory path in the database to look at the C:\ but it doesn't work, it says invalid directory, I think the PDF report file needs to be on the server where the database is installed. Is there a way I can pick the PDF file from the local machine instead of the server where the database is installed?
Im not too sure what is the way forward, All I need is to generate a PDF file and mail it.
The procedure that I'm using to send the email attachment is :-
CREATE OR REPLACE PROCEDURE email_attachment(
xfilename VARCHAR2,
xloc VARCHAR2) IS
conn utl_smtp.connection;
BEGIN
conn := Send_Mail.begin_mail(
sender => '[email protected]',
recipients => '[email protected]',
subject => 'Attachment Test',
mime_type => Send_Mail.MULTIPART_MIME_TYPE);
Send_Mail.attach_text(
conn => conn,
DATA => '<b>This is a test Email.<b>',
mime_type => 'text/html');
send_mail.attach_base64_fromfile(
conn => conn,
filename => xfilename,--'test.pdf',
floc => xloc,--'File directory',
mime_type => 'application/octet',
inline => TRUE);
Send_Mail.end_attachment( conn => conn );
Send_Mail.end_mail( conn => conn );
Thanks any help would be appreciated.

Hi,
in the forms 6i email with attachment can be sent only through database folder/file. From the client it can not be.
Here is one alternate solution.
1. Share the folder from db server which is used for email directory and keep changeable for everyone.
2. After generate the report like RUN_PRODUCT keep the below command.
HOST('XCOPY CLIENT_PATH\FILE_NAME SERVER_PATH');
3. This command will transfer file from client to db server. After this execute your procedure which is sending email.
Hope it will work.

Calling stored procedures with parameters with the Database Connectivity Toolkit

Hi all,
I am new to the forum and am having difficulty finding a solution to a particular problem I am having regarding using the LabVIEW Database Connectivity Toolkit on a project I am currently working on at my job. I have a database in which I have tables and stored procedures with parameters. Some of these stored procedures have input, output, and return parameters.
I have been trying to follow this example but to no avail: http://digital.ni.com/public.nsf/allkb/07FD130746083E0686257300006326C4?OpenDocument
One such stored procedure I am working on implementing is named "dbo.getAllowablePNs", which executes "SELECT * from DeviceType" (DeviceType is the table). In this case, it does not require an input parameter, it has an output parameter that generates the table [cluster], and has a return parameter which returns an integer value (execution status code) to show if an error occurred. The DeviceType table has 3 columns; ID (PK, int, not null), PN (nvarchar(15), null), and NumMACAddresses (int, null). I have gone over many examples and have talking to NI support to try to implement this and similar stored procedures in LabVIEW but have not been successful. I am able to connect to the database with the Open Connection VI without error, but am running into some confusion following this step. I am then trying to use the Create Parameterized Query VI to call the stored procedure and set the parameters. I assume I would then use the Set Parameter Value VI for each parameter that is wired into the parameters input on the previous Parameterized Query VI? I am also having some confusion during and following these steps as well. I would greatly appreciate any advice or suggestions anyone might have in regards to this situation as I am not a SQL expert. Also, I would be happy to provide any more information that would be helpful.
Regards,
Jon
Solved!
Go to Solution.

Also, I don't know if this would be helpful but here is the actual stored procedure in SQL:
CREATEPROCEDURE [dbo].[getLastSequenceNumber]
@p1 nvarchar(10)='WO-00000'
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SETNOCOUNTON;
-- Insert statements for procedure here
selectmax(SequenceNumber)from Devices where WorkOrderNumber= @p1
END
