Client side database setting?

Hi all,
I currently have an application deployed on the j2ee server. Using the oracle thin driver and datasource. Which all part of the program works fine, if I run it in the server.
Now, I have copied the files to another remote machine, having a batch file, myApp.ear and some JAR. The program works on the client, but only a part of it. It happens that when the GUI of my program try to use the datasource, it will fail and respone with a "no suitable driver" error. But when using datasource through entity beans, it will work fine.
Can anyone suggest how to solve the problem?
Do I need to do anything to make the program knows where the driver is?
Thanks a lot.

If you're creating the database connection on the remote machine then it will need to be able to find the oracle driver.
Check to see if the driver is on the machine.

Client side result set cache

Hello,
I try to get the client side result set cache working, but i have no luck :-(
I'm using Oracle Enterprise Edition 11.2.0.1.0 and as client diver 11.2.0.2.0.
Executing the query select /*+ result_cache*/ * from p_item via sql plus or toad will generate an nice execution plan with an RESULT CACHE node and the v$result_cache_objects contains some rows.
After I've check the server side cache works. I want to cache the client side
My simple Java Application looks like
private static final String ID = UUID.randomUUID().toString();
private static final String JDBC_URL = "jdbc:oracle:oci:@server:1521:ORCL";
private static final String USER = "user";
private static final String PASSWORD = "password";
public static void main(String[] args) throws SQLException {
OracleDataSource ds = new OracleDataSource();
ds.setImplicitCachingEnabled(true);
ds.setURL( JDBC_URL );
ds.setUser( USER );
ds.setPassword( PASSWORD );
String sql = "select /*+ result_cache */ /* " + ID + " */ * from p_item d " +
"where d.i_size = :1";
for( int i=0; i<100; i++ ) {
OracleConnection connection = (OracleConnection) ds.getConnection();
connection.setImplicitCachingEnabled(true);
connection.setStatementCacheSize(10);
OraclePreparedStatement stmt = (OraclePreparedStatement) connection.prepareStatement( sql );
stmt.setLong( 1, 176 );
ResultSet rs = stmt.executeQuery();
int count = 0;
for(; rs.next(); count++ );
rs.close();
stmt.close();
System.out.println( "Execution: " + getExecutions(connection) + " Fetched: " + count );
connection.close();
private static int getExecutions( Connection connection ) throws SQLException {
String sql = "select executions from v$sqlarea where sql_text like ?";
PreparedStatement stmt = connection.prepareStatement(sql);
stmt.setString(1, "%" + ID + "%" );
ResultSet rs = stmt.executeQuery();
if( rs.next() == false )
return 0;
int result = rs.getInt(1);
if( rs.next() )
throw new IllegalArgumentException("not unique");
rs.close();
stmt.close();
return result;
100 times the same query is executed and the statement exection count is incemented every time. I expect just 1 statement execution ( client database roundtrip ) and 99 hits in client result set cache. The view CLIENT_RESULT_CACHE_STATS$ is empty :-(
I'm using the oracle documentation at http://download.oracle.com/docs/cd/E14072_01/java.112/e10589/instclnt.htm#BABEDHFF and I don't kown why it does't work :-(
I'm thankful for every tip,

I wanted to post a follow-up to (hopefully) clear up a point of potential confusion. That is, with the OCI Client Result Cache, the results are indeed cached on the client in memory managed by OCI.
As I mentioned in my previous reply, I am not a JDBC (or Java) expert so there is likely a great deal of improvement that can be made to my little test program. However, it is not intended to be exemplary, didactic code - rather, it's hopefully just enough to illustrate that the caching happens on the client (when things are configured correctly, etc).
My environment for this exercise is Windows 7 64-bit, Java SE 1.6.0_27 32-bit, Oracle Instant Client 11.2.0.2 32-bit, and Oracle Database 11.2.0.2 64-bit.
Apologies if this is a messy post, but I wanted to make it as close to copy/paste/verify as possible.
Here's the test code I used:
import java.sql.ResultSet;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import oracle.jdbc.pool.OracleDataSource;
import oracle.jdbc.OracleConnection;
class OCIResultCache
public static void main(String args []) throws SQLException
    OracleDataSource ods = null;
    OracleConnection conn = null;
    PreparedStatement stmt = null;
    ResultSet rset = null;
    String sql1 = "select /*+ no_result_cache */ first_name, last_name " +
                  "from hr.employees";
    String sql2 = "select /*+ result_cache */ first_name, last_name " +
                  "from hr.employees";
    int fetchSize = 128;
    long start, end;
    try
      ods = new OracleDataSource();
      ods.setURL("jdbc:oracle:oci:@liverpool:1521:V112");
      ods.setUser("orademo");
      ods.setPassword("orademo");
      conn = (OracleConnection) ods.getConnection();
      conn.setImplicitCachingEnabled(true);
      conn.setStatementCacheSize(20);
      stmt = conn.prepareStatement(sql1);
      stmt.setFetchSize(fetchSize);
      start = System.currentTimeMillis();
      for (int i=0; i < 10000; i++)
        rset = stmt.executeQuery();
        while (rset.next())
        if (rset != null) rset.close();
      end = System.currentTimeMillis();
      if (stmt != null) stmt.close();
      System.out.println();
      System.out.println("Execution time [sql1] = " + (end-start) + " ms.");
      stmt = conn.prepareStatement(sql2);
      stmt.setFetchSize(fetchSize);
      start = System.currentTimeMillis();
      for (int i=0; i < 10000; i++)
        rset = stmt.executeQuery();
        while (rset.next())
        if (rset != null) rset.close();
      end = System.currentTimeMillis();
      if (stmt != null) stmt.close();
      System.out.println();
      System.out.println("Execution time [sql2] = " + (end-start) + " ms.");
      System.out.println();
      System.out.print("Enter to continue...");
      System.console().readLine();
    finally
      if (rset != null) rset.close();
      if (stmt != null) stmt.close();
      if (conn != null) conn.close();
}In order to show that the results are cached on the client and thus server round-trips are avoided, I generated a 10046 level 12 trace from the database for this session. This was done using the following database logon trigger:
create or replace trigger logon_trigger
after logon on database
begin
if (user = 'ORADEMO') then
    execute immediate
    'alter session set events ''10046 trace name context forever, level 12''';
end if;
end;
/With that in place I then did some environmental setup and executed the test:
C:\Projects\Test\Java\OCIResultCache>set ORACLE_HOME=C:\Oracle\instantclient_11_2
C:\Projects\Test\Java\OCIResultCache>set CLASSPATH=.;%ORACLE_HOME%\ojdbc6.jar
C:\Projects\Test\Java\OCIResultCache>set PATH=%ORACLE_HOME%\;%PATH%
C:\Projects\Test\Java\OCIResultCache>java OCIResultCache
Execution time [sql1] = 1654 ms.
Execution time [sql2] = 686 ms.
Enter to continue...This is all on my laptop, so results are not stellar in terms of performance; however, you can see that the portion of the test that uses the OCI client result cache did execute in approximately half of the time as the non-cached portion.
But, the more compelling data is in the resulting trace file which I ran through the tkprof utility to make it nicely formatted and summarized:

Hi,can anyone guide me on what is client side database & grid database.....

what is client side database & grid database..........and what is the difference between Dataguard and stand by database() these are interview questions.........i am dba learner pls explanin me.......
thanks u all...

I'm not trying to be funny or mean, but, in my experience, if you don't know what a product/tool/component is, then you should say so. If you give the impression that you do know about a technology in your interview and you are hired based upon that premise, you might find yourself struggling mightily when your employer asks you to 'implement DataGuard by the end of the week'...
Just some advice. Good luck in your interview!

Can Flex access client-side databases?

I know the usual paradigm is for the database to be on the server, and my app does have a server-side DB, but it is data-manipulation intensive, and I wanted to be able to copy a subset of data from the postgres DB on the server to a postgres DB on the client to speed up the local manipulation.
I was planning to deploy outside the browser using AIR.

Is XML-SQL Utility for Java run on Client Side?

A question about the XML-SQL Utility for Java
When a client program connect to a Oracle database (the clinet program and Oracle DB is run on two different machine. Oracle 8i is used) and use the oracle.xml.sql.query.OracleXMLQuery Class (form the XSU) to generate XML by given a SQL query. I want to know the transforation process is execute in the Clinet side or the database?
Is there any method that i can retrieve the XML directly from the database rather then doing the transformation form the Client side?

How can i load file into database from client-side to server-side

i want to upload file from client-side to server-side, i use the following code to load blob into database.
if the file is in the server-side, it can work, but if it in the client-side, it said that the system cannot find the file. i think it only will search the file is in the server-side or not, it will not search the client-side.
how can i solve it without upload the file to the server first, then load it into database??
try
ResultSet rset = null;
PreparedStatement pstmt =
conn.prepareStatement ("insert into docs values (? , EMPTY_BLOB())");
pstmt.setInt (1, docId);
pstmt.execute ();
// Open the destination blob:
pstmt.setInt (1, docId);
rset = pstmt.executeQuery (
"SELECT content FROM docs WHERE id = ? FOR UPDATE");
BLOB dest_lob = null;
if (rset.next()) {
dest_lob = ((OracleResultSet)rset).getBLOB (1);
// Declare a file handler for the input file
File binaryFile = new File (fileName);
FileInputStream istream = new FileInputStream (binaryFile);
// Create an OutputStram object to write the BLOB as a stream
OutputStream ostream = dest_lob.getBinaryOutputStream();
// Create a tempory buffer
byte[] buffer = new byte[1024];
int length = 0;
// Use the read() method to read the file to the byte
// array buffer, then use the write() method to write it to
// the BLOB.
while ((length = istream.read(buffer)) != -1)
ostream.write(buffer, 0, length);
pstmt.close();
// Close all streams and file handles:
istream.close();
ostream.flush();
ostream.close();
//dest_lob.close();
// Commit the transaction:
conn.commit();
conn.close();
} catch (SQLException e) {

Hi,
Without some more details of the configuration, its difficult to know
what's happening here. For example, what do you mean by client side
and server side, and where are you running the upload Java application?
If you always run the application on the database server system, but can't
open the file on a different machine, then it sounds like a file protection
problem that isn't really connected with the database at all. That is to
say, if the new FileInputStream (binaryFile) statement fails, then its not
really a database problem, but a file protection issue. On the other hand,
I can't explain what's happening if you run the program on the same machine
as the document file (client machine), but you can't write the data to the
server, assuming the JDBC connection string is set correctly to connect to
the appropriate database server.
If you can provide some more information, we'll try to help.

Client side Vs, Database side

Hi,
My company is a partner of SAP and we supply Crystal Reports Server along with our web application for reports generation
My questions are
1. When a user generates a report from the web application what actions/processes/other actions are taking place on the client side and which actions are taken on the database side
2. what is the workflow since the user generates a report until the result set is displayed in the web browser?
I also like to know where each report component (e.g. sub report, formula, parameter, etc.) is being processed
Thanks
Barry

Establish a connection through RF modem's on client & server side & to set up PPP communication for data transfer

hi
can any1 over here help me out in how to establish connection between 2 RF modem's for data transfer , between client & server USing LABVIEW?
I want to establish a connection between 2 PC's through RF modem on client & server side & to set up PPP communication for data transfer.
(I have tried data transfer through RS-232 using TCP/IP whn the 2 PC's are connected over ethernet... which is working.
I also tried connecting loopback cable between 2 PC's COM port & geting data transfer using VIsa configure serial port & other visa functions ... which is working)
can u guide me how to establish connection between 2 RF modem's using LABview?
& how does the data transfer take place between 2 RF modems through RS-232?
is it using TCP/IP?
If you got any links to go abt this issue do send me related links .. or any examples .....
I am currently using Labview version 8.
Waiting in anticipation.. reply ASAP..
thanking you
Regards
Yogan..

Howdy yogan,
Maybe you could clarify a few things for me, and we'll see how we can help ya. TCP/IP protocol occurs through an ethernet connection; RS-232 communication occurs through an RS-232 serial connection, typically through a cable that has a DB9 connector on both ends. Do you mean that the RF modems in question have the option to communicate via RS-232 and/or via TCP/IP ethernet? Specific information like the manufacturer of your RF modems, the model number of your RF modems, and how you connect the modems to the PC would enable us to give you more efficient support.
You can check our Instrument Driver Network (IDNet) to see if a plug-and-play/IVI driver already exists for your RF modem. (You'll need to know its manufacturer and model number.) In the case that you do find an IDNet driver for your modem, you can use this KnowledgeBase article for instructions on how to use the driver.
Another excellent resource to consider is the NI Example Finder. You can access this within LabVIEW by navigating to Help»Find Examples and then searching for serial or TCP/IP examples.

To print client side you must install the Crystal Reports ActiveX control. The security warning is the same as any other ActiveX control you'd install. Simply click the yellow bar at the top of your browser screen, or follow the directions to install it.
If you don't want to install the ActiveX control you can use the Pdf print mode instead.

How to set client side validations in ADF Forms

check for client side validations on submission of a form and display custom error messages.

Hi,
you really should take more time in phrasing out a question. I have no clue of what you are actually asking for. Note that ADF Faces performs client side validation e.g. for required fields. Just in case this was the question

How To Update A Table View From Client Side !!!!

Hi I would like to update a table view from the Client Side. So that the user can keep updating the relevent data on the client and when they have finally finished they can press Save so the entire page is then sent to the Server.
Does anyone know how to do this, I guess u have to use the EPCM, I have just started on it and would really appreciate some Help.
Thanks,
Emmanuel.

This is what I found :-
There are a couple of ways to approach this.
1) load the excel spreadsheet into the database "as is". You can use interMedia
text to convert the .xls file into a .htm file (HTML) or use iFS (see
http://technet.oracle.com/
for
more info on that) to parse it as well. InterMedia text will convert your XLS
spreadsheet into a big HTML table (easy to parse out what you need at that
point)
2) Using OLE automation, a program you write can interact with Excel, request
data from a spreadsheet, and insert it. Oracle Forms is capable of doing this
for example as is other languages environments. In this fashion, you can remove
the "manual" and "sqlldr" parts -- your program can automatically insert the
data.
3) You can write a VB script that uses ODBC or Oracle Objects for OLE (OO4O) in
Excel. This VB script would be able to put selected data from the spreadsheet
into the database. We would recommend OO4O. It provides an In-Process COM
Automation Server that provides a set of COM Automation interfaces/objects for
connecting to Oracle database servers, executing queries and managing the
results. OO4O is available from
