Database post example
hi, some time ago i asked in this forum about examples about flash/sql, i got this as a reference (tnx ned murphy):
http://www.gotoandlearn.com/play?id=20
this seems to work and the example is clear and great for part of the job, though it only shows how to read from the database. as i said, that is only part of the job since it only shows how to read from the database, i also need to send to the database a string of about 7k (more or less 5000 to 700 bytes, in a single string) i would like to do that trough php, since it should use the same php session id. does anyone have references to this? (write to a databse from flash, if possible using php as middle layer)
tnx
Google is one of the best resources available for finding things such as you are looking for. Use search terms such as "AS3 PHP SQL" and maybe throw on "tutorial" as well, and you should come up with a few useful links you can build from.

Passing Array of java objects to and from oracle database-Complete Example
Hi all ,
I am posting a working example of Passing Array of java objects to and from oracle database . I have struggled a lot to get it working and since finally its working , postinmg it here so that it coudl be helpful to the rest of the folks.
First thinsg first
i) Create a Java Value Object which you want to pass .
create or replace and compile java source named Person as
import java.sql.*;
import java.io.*;
public class Person implements SQLData
private String sql_type = "PERSON_T";
public int person_id;
public String person_name;
public Person () {}
public String getSQLTypeName() throws SQLException { return sql_type; }
public void readSQL(SQLInput stream, String typeName) throws SQLException
sql_type = typeName;
person_id = stream.readInt();
person_name = stream.readString();
public void writeSQL(SQLOutput stream) throws SQLException
stream.writeInt (person_id);
stream.writeString (person_name);
ii) Once you created a Java class compile this class in sql plus. Just Copy paste and run it in SQL .
you should see a message called "Java created."
iii) Now create your object Types
CREATE TYPE person_t AS OBJECT
EXTERNAL NAME 'Person' LANGUAGE JAVA
USING SQLData (
person_id NUMBER(9) EXTERNAL NAME 'person_id',
person_name VARCHAR2(30) EXTERNAL NAME 'person_name'
iv) Now create a table of Objects
CREATE TYPE person_tab IS TABLE OF person_t;
v) Now create your procedure . Ensure that you create dummy table called "person_test" for loggiing values.
create or replace
procedure give_me_an_array( p_array in person_tab,p_arrayout out person_tab)
as
l_person_id Number;
l_person_name Varchar2(200);
l_person person_t;
l_p_arrayout person_tab;
errm Varchar2(2000);
begin
l_p_arrayout := person_tab();
for i in 1 .. p_array.count
loop
l_p_arrayout.extend;
insert into person_test values(p_array(i).person_id, 'in Record '||p_array(i).person_name);
l_person_id := p_array(i).person_id;
l_person_name := p_array(i).person_name;
l_person := person_t(null,null);
l_person.person_id := l_person_id + 5;
l_person.person_name := 'Out Record ' ||l_person_name ;
l_p_arrayout(i) := l_person;
end loop;
p_arrayout := l_p_arrayout;
l_person_id := p_arrayout.count;
for i in 1 .. p_arrayout.count
loop
insert into person_test values(l_person_id, p_arrayout(i).person_name);
end loop;
commit;
EXCEPTION WHEN OTHERS THEN
errm := SQLERRM;
insert into person_test values(-1, errm);
commit;
end;
vi) Now finally create your java class which will invoke the pl/sql procedure and get the updated value array and then display it on your screen>Alternatively you can also check the "person_test" tbale
import java.util.Date;
import java.io.*;
import java.sql.*;

public class ArrayDemo
public static void passArray() throws SQLException
Connection conn = getConnection();
ArrayDemo a = new ArrayDemo();
Person pn1 = new Person();
pn1.person_id = 1;
pn1.person_name = "SunilKumar";
Person pn2 = new Person();
pn2.person_id = 2;
pn2.person_name = "Superb";
Person pn3 = new Person();
pn3.person_id = 31;
pn3.person_name = "Outstanding";
Person[] P_arr = {pn1, pn2, pn3};
Person[] P_arr_out = new Person[3];
ArrayDescriptor descriptor =
ArrayDescriptor.createDescriptor( "PERSON_TAB", conn );
ARRAY array_to_pass =
new ARRAY( descriptor, conn, P_arr);
OracleCallableStatement ps =
(OracleCallableStatement )conn.prepareCall
( "begin give_me_an_array(?,?); end;" );
ps.setARRAY( 1, array_to_pass );
ps.registerOutParameter( 2, OracleTypes.ARRAY,"PERSON_TAB" );
ps.execute();
oracle.sql.ARRAY returnArray = (oracle.sql.ARRAY)ps.getArray(2);
Object[] personDetails = (Object[]) returnArray.getArray();
Person person_record = new Person();
for (int i = 0; i < personDetails.length; i++) {
person_record = (Person)personDetails;
System.out.println( "row " + i + " = '" + person_record.person_name +"'" );
public static void main (String args[]){
try
ArrayDemo tfc = new ArrayDemo();
tfc.passArray();
catch(Exception e) {
e.printStackTrace();
public static Connection getConnection() {
try
Class.forName ("oracle.jdbc.OracleDriver");
return DriverManager.getConnection("jdbc:oracle:thin:@<<HostNanem>>:1523:VIS",
"username", "password");
catch(Exception SQLe) {
System.out.println("IN EXCEPTION BLOCK ");
return null;
and thats it. you are done.
Hope it atleast helps people to get started. Comments are appreciated. I can be reached at ([email protected]) or [email protected]
Thanks
Sunil.sHi Sunil,
I've a similar situation where I'm trying to insert Java objects in db using bulk insert. My issue is with performance for which I've created a new thread.
http://forum.java.sun.com/thread.jspa?threadID=5270260&tstart=30
I ran into your code and looked into it. You've used the Person object array and directly passing it to the oracle.sql.ARRAY constructor. Just curios if this works, cos my understanding is that you need to create a oracle.sql.STRUCT out of ur java object collection and pass it to the ARRAY constructor. I tried ur way but got this runtime exception.
java.sql.SQLException: Fail to convert to internal representation: JavaBulkInsertNew$Option@10bbf9e
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:146)
at oracle.jdbc.oracore.OracleTypeADT.toDatum(OracleTypeADT.java:239)
at oracle.jdbc.oracore.OracleTypeADT.toDatumArray(OracleTypeADT.java:274)
at oracle.jdbc.oracore.OracleTypeUPT.toDatumArray(OracleTypeUPT.java:115)
at oracle.sql.ArrayDescriptor.toOracleArray(ArrayDescriptor.java:1314)
at oracle.sql.ARRAY.<init>(ARRAY.java:152)
at JavaBulkInsertNew.main(JavaBulkInsertNew.java:76)
Here's a code snippet I used :
Object optionVal[] = {optionArr[0]}; // optionArr[0] is an Option object which has three properties
oracle.sql.ArrayDescriptor empArrayDescriptor = oracle.sql.ArrayDescriptor.createDescriptor("TT_EMP_TEST",conn);
ARRAY empArray = new ARRAY(empArrayDescriptor,conn,optionVal);If you visit my thread, u'll see that I'm using STRUCT and then pass it to the ARRAY constructor, which works well, except for the performance issue.
I'll appreciate if you can provide some information.

Groupwise database post office errors
Thanks in advance for any answers you can give me.
We had some corruption in our groupwise databases today, We have two users who's gwcheck comes back as
Problem 39- Unknown file useremc.dba - 64652288 bytes,
They cannot login to their mailbox and when you email them you the message
Tried to change a locked setting
Error = D013
What would be the best recourse in fixing this?
We also have a few people whos password is now gone. everything is there but you cant login, if you try to change it in console one it changes, but it does not update the password in groupwise,
any help would be appreciated.

groupwise 8.02 hotfix 1
What kind of corruption did you have? And what happened that led to this?
It would be good to know what OS, version and SP level you are running on and what filesystem the GroupWise dibs are on?
As for the unknown file error... could be normal as the file mentioned is a backup file or the database, typically created by GroupWise during certain gwcheck maintenance tasks.
Is there a .db file for the user in question (e.g. useremc.db in the offusr folder?).
In all cases tread carefully as you first need to determine what might be broken before trying to fix anything.

Non-trivial Database editing examples
Hi everyone,
I'm searching for examples of database editing and setting properties that are more complex than the ones that ship with LabWindows/CVI. As far as I can tell, these don't even edit the database, they just manipulate aliases and parse through the different clusters/frames/signals, despite being titled "Managing Databases". Anyone out there know where I can find this kind of info? Thanks!
- Brandon
EDIT: I'm using the XNET APIThose examples do edit a database, the database just happens to be in memory instead of on disk. To be honest whenever I need to actually edit a DBC file I usually resort to Vectors database editing software which runs without needing any particular hardware or software license.
But if you are strickly in the XNET world, import the DBC, then use the "Database Editor" to edit the XNET database. This is saved as an XML but contains much of the same information as DBC. You can also programatically import a DBC to use in XNET if you periodically get updates.
My conversion library does this in the examples.

Question about JAI posted example?

I just wondered if I could ask, I found this example JAI code on the web. The code compiles, but in the example said they missed out some lines at the begining, do you these missing lines were to read-in a image?

int count = 0; // Temporary counter.
for(int w=0;w<width;w++) // Fill the array with a pattern.
for(int h=0;h<height;h++){
data[count+0] = (count % 2 == 0) ? (byte)255: (byte) 0;
data[count+1] = 0;
data[count+2] = (count % 2 == 0) ? (byte) 0: (byte)255;

tiledImage.setData(raster);

Modifying an Access database posted in a SharePoint doclib
I inherited the maintenance of a database used to store data for reporting. I needed to add a simple new query and "union" it to a group of existing queries.
When opening the database, I am prompted to open it read only, or download a copy to my PC to edit (and when finished, upload).
When I download, the queries I need to add to "disappear" - they are no longer listed in the left hand list of objects.
Thinking here is that those queries are soemehow associated with daya that exists only in SharePoint, and not being available on my desktop, no longer appear.
How can I:
a. Determine what those queries are connected to, and
b. Get the queries to appear in the downloaded version so I can peform the necessary edits?
Thnaks in advance.This doesn't work. When you use the Save As... dialog box and open a SharePoint location using HTTP (WebDAV) connection, the dialog box hangs.
Why does every other piece of software use the Windows 7 dialog box but Adobe Reader XI and any software using the Adobe Acrobat 11.0.0.379 Plug-In (e.g. Firefox or IE) not work? -
Could anyone post examples about sendingand receiving messages with SOAP
I am newbie, and want to learn SOAP. Anyone can tell me
where to find many examples about communication between client and server
based on SOAP. The example is in java code should be best.
Many thanks in advanceJava tutorial at http://java.sun.com/webservices/docs/ea1/tutorial/doc/JAXM.ws.html#63873
should be a good starting point.
I have sample code, which creates SOAP header and SOAP elements. THis code gives an idea to create SOAP messages and to parse the SOAP response. Hope this helps.
I pass Application ID and password in SOAP header, used by the Webservices provider to verify my application. In the SOAP elments, I pass a string (called ticket) and ip address. Web services provider will verify the string and return the response along with some attributes related to the user (extended attributes).

Need good example HTTP POST Business Service
Hi guys,
I've looked into the provided Reference Implementations in JDE for HTTP Post examples, but they only provided a business service (JRH90I13) and published business service (JPRH90I0) without any C BSFN to execute them. Does anyone have possible examples of how this works?
Thanks in advance.Hi Gregory,
In fact when i used route node to invoke a business service i modified "URL dynamically by setting the value in the pipeline variable $outbound", it worked here.
Same i tried on Service Callout, it did not work. Also when we create a service callout action it expects us to select either "confugure soap body" or "configure payload document" followed by
1) Request Document variable
2) Response Document variable.
What parameter should i set for above fields?
Thanks,

We currently have a SharePoint 2010 farm, running on a SQL Server 2008 R2 Standard database. On one of the SharePoint 2010 servers, we have an instance of Reporting Services 2008 Enterprise running in SharePoint integrated mode. (We require Enterprise
for data-driven subscriptions)
We'd like to upgrade to Reporting Services 2012 for Data Alerts and a few other new features. However, I noticed something on
this blog stating that the SharePoint 2010 database server edition needs to match the Reporting Services edition. My concern is that I've not seen any official mention of this in Microsoft's documentation, and would like to avoid upgrading to Enterprise
for the SharePoint 2010 database if I can avoid it.
So, what I'd like to run is:
SharePoint 2010
SharePoint database: SQL Server 2008 R2 Standard
Reporting Services 2012 Enterprise
Reporting Services database: same as SharePoint database, so SQL Server 2008 R2 Standard
Is this possible? Or do I need to upgrade the SharePoint database to SQL Server 2008 R2 Enterprise?
Alternatively, could I install a separate database engine just for Reporting Services to host its databases (for example, SQL Server 2012 Enterprise), so I don't have to mess around with upgrading the SP database?While you don't need to upgrade your SQL 2008 R2 to 2012, you will need to install an instance of SQL 2012 & SSRS 2012. They can be side-by-side and independent of each other. The following blog post provides steps to do so,

Create a database link to access SqlServer 2005 view from oracle 11gr2
Hi All,
Greetings for the day.
Though I have seen quite a few posts but just wanted to cross-verfiy and double check hence posting.
Oracle Database : 11gr2
OS :SOLARIS SPARC 64 Bit
SQL Server Database : Sql Server 2005
OS : Windows 2003 32 Bit
The requirement is to access a view residing in the SQL Server 2005 Database using the Oracle Database. This involves creation of a Database link in the Oracle Database to access the SQL Server.
Can you suggest which approach should i follow ( I am able to understand that both do the same job ):
How to Configure DG4MSQL (Oracle Database Gateway for MS SQL Server) 64bit Unix OS (Linux, Solaris, AIX,HP-UX) post install [ID 562509.1]or
How to Configure DG4ODBC on 64bit Unix OS (Linux, Solaris, AIX, HP-UX Itanium) to Connect to Non-Oracle Databases Post Install [ID 561033.1]Will they do the same job ? And can they be used on any OS and version of the SQL Server Database as version information for SQL Server is not specified anywhere?
Please let me know so that I can it forward with Business for approvals and budgetting.
Regards
KKYour question is similar to the post: Oracle 11gr2 connection to Sql Server using dg4msql problem
Please visit: http://stackoverflow.com/questions/4658942/oracle-11gr2-connection-to-sql-server-using-dg4msql-problem
Answer on the website:
You seem to be using the Gateway for MySQL set-up rather than the Heterogeneous Gateway (for ODBC connections). Here is an overview of the process
On SQL Server create a database user and give it read access to the database/tables you want to read via the Oracle database link.
In the gateway home each SQL Server database you want to access should have an init.ora located in $OH/dg4msql/admin in the form initsid.ora where sid is the name of the database to be used in the link (e.g. initbob.ora), so create one
HS_FDS_CONNECT_INFO=msserver1:1234//Example_Database
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
HS_TRANSACTION_MODEL=READ_ONLY
You must now add the new sid to the listener.ora in the gateway home using an additional SID_DESC section inside the existing SID_LIST, for example
(SID_DESC =
(SID_NAME=bob)
(ORACLE_HOME=/oracle/gateway/product/11.2.0)
(ENVS=LD_LIBRARY_PATH=/oracle/gateway/product/11.2.0/dg4msql/driver/lib;/oracle/gateway/product/11.2.0/lib)
(PROGRAM=dg4msql)
You should now stop and restart the gateway listener so that the new sid becomes active. NB a reload is not enough.
You must now add the new sid in the tnsnames.ora file for the listener of each database in which you will create a link. You don't need to do this in the gateway home unless it is also a database home in which you will create a database link.
bob =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = severname.example.com)(PORT = 1690))
(CONNECT_DATA = (SID = bob))
(HS = OK)
NB: The host and port are for the gateway not for the SQL Server database
In each database that requires a link to the MS-SQL database you should create a database link to your new gateway sid.
CREATE PUBLIC DATABASE LINK bob
CONNECT TO "ms_user" IDENTIFIED BY "ms-passwd" USING 'bob';
where ms-user and ms-password are the SQL Server user you created right at the start.
Now you can test the new database link
SELECT COUNT(*) FROM "Table_Name"@bob;
Once you have this working you can alter the initsid.ora file to add parameters to suit your connection. If you do it this way you can easily add and manage many different databases via the gateway.

Please compare
methods in C # to connect to SQL Server
database (for example,
3-tier architecture of traditional and
entity Framework(linq to entity or linq to sql object model)
and Linq to SQL) in terms of speed, quality and functionality
to give me tips.
Thank you.
Mojtaba Malakouti.That means we need to compare and post the results here?

If I am missing what you are asking then please provide instructions as to how to find this error information. You are posting the error message for the exception but not printing the stack trace.
Far as I can tell you are printing more information with each exception (for example "Exception creating Users table") but you did not post what that was, that info would localize the problem.
As a guess the problem is when you extract the fields via the query. You are using named values rather than indexes and you use "select *" rather than specifically naming the columns. Some databases (for example Oracle), require that using names must be in exactly the same order as the query returns them. You have no idea what that order is because you use "select *"
Finally it would be a LOT easier if you wrote classes that did nothing but the database operations. NO GUI CODE. You then test that code to make sure it works. Once that code works then you write gui code which uses those classes. Besides making it easier to understand you are also more likely to get assistance since there is less code to look at.
