Defining database

first line of the abap editor is report statement,in that report statement we use line-size,line-count,message-id & defining database.what is defining database?

Hi,
The defining database :
This addition shows that the current program is the database program of the logical database ldb. The name of this logical database has a maximum length of 20 characters. Logical databases are maintained with the tool Logical Database Builder of the ABAP Workbench, in which the framework program is generated automatically including the statement REPORT. The name of the framework program is SAPDBldb.
Example
Introduction of the logical database F1S.
REPORT sapdbf1s DEFINING DATABASE f1s.
Hope it is useful.
Thanks,
Sandeep.

The "DEFINING DATABASE ldb " addition in "REPORT" statment

Hi all
I wonder what the "DEFINING DATABASE ldb " addition in "REPORT" statment is involve to?
cause I didn't understand the SAP help of this addition!
Thanks.

When defining logical databases (via SE36), the underlying database program needs to have this addition to the REPORT statement. See SAPDBSDF for logical database SDF as an example.

How can i define database name in oracle ADI

Hai Friends,
I am facing a problem when i am going to define database name in oracle ADI there is a error u can enter minimum 6 char database name but my database name is PROD it is only 4 char long. how can i define can i will change the database name. Please suggest me.
If u have any query regarding oracle apps plse discuss with me.
Many thanks
Ghanshyam khetan

Database is used internally by ADI and does not have any relationship to the name of your database.
Using ADI I am able to create a database with the following:
Name - My Wacky Database
GWYUID and FNDNAM as usual
Connect String - VIS
I'm able to signon and work successfully with that definition. The connect string is more important in this scenario as that tells the networking layer which database to actually talk to. As you can see here mine is only three characters.

Modifying .PRM file for user defined database functions

Hi,
Currently we have the BOXI 3.1.8 Universe in oracle database and we are planning to migrate to SQL server 2008.And the universe contains few oracle functions and user defined functions in the universe objects.
In the way of migration we are planning to have both Oracle and SQL Server database connecting to single universe. To make the universe generic we have identified the objects using user defined functions and trying to push it to the database.
Since there are a few differences in the way oracle and SQL Server functions are invoked, we have decided to edit the .PRM files available in the path D:\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\dataAccess\connectionServer\jdbc , so that we have a common way of invoking the functions.
Invoking functions:
SQL Server : <SchemaName>.<function>
Oracle: <function>
1.Is there any problem if I edit the .PRM?
2.Whether these changes will work fine?
3.Whether the reports will run fine if I use those objects in the reports?
Thanks,
Lavanyaa

Hi Lavanyaa,
The PRM files actually state the functions that are normally available in a database, including the standard format.
They are what drives the list of functions available when you build the SELECT definition or CONDITION definitions in Information designer... The fact that a function needs aggregation or/not is also determined in there.
However:
The SQL that you provide in the universe is what will be sent to the database and that must be 'understood' by the database.
So it's not as simple as changing the PRM file and you will be able to speak 'universal' SQL in your universes.
Fortunately:
That complexity is taken away from you when you create a multisource database.
You will speak 'data federator' SQL in the universe. Data federator will take care of translating it to the right syntax for each database. Notice you will probably need some customization to determine how a SQL will be handled when you need to query two databases, as the default is not automatically the best way performance wise.
Hope this helps,
Marianne

Designing a well defined database access javabean

Hi All
Can you please help me with the basic layout of how
a well defined javabean accessing the database should look like?
thread safe too..
It should have the following basc methods
JavaClass get(String id)
JavaClass[] getAll()
void save ()
void delete()hope that gives you an idea

Hi Jos
Lets say we have a bussiness class named Car then basically the Car class would
be represented in the database as
carId
carName
carModel etc..
I Know how to get this data into a javabean but i do not know if it is correct
Example
public class Car
      private Connection conn
      private String carID
      private String carName
      private String carModel
      /* getters and setters .....*/
      public Car get(String id) throws Exception {
            String sql = "SELECT * FROM Car WHERE carID = " + this.carID;
      //and so forth with deleting a car saving it etc...What i would like to know is what is a good standard of coding such a class to be thread safe
and use minimal resources?
the parameter would be in this as it would be the current class used by lots of clients

How define database performance?

Hi all
I have a question about performance.
I have an Oracle database installed on Xeon server

Define database at Logon

At the opening of my main form an On_Logon trigger/procedure is
set off.
The purpose of this trigger is to perform an OCI (or whatever
works) call via a cursor or command that will connect my
Developer application with the database I want to process from.
I have already tried the following methods. The first compiled
but errored out in the application. The other two would not
compile.I am playing with OCI now.
1. BLOCK_NAME := ('SET(CURRENT_SCHEMA = NAME)');
2. connection_id := EXEC_SQL.OPEN_CONNECTION('alter session set
current_schema = DATABASE');
cursor_number := EXEC_SQL.OPEN_CURSOR(CONNECTION_ID);
EXEC_SQL.PARSE(connection_id, cursor_number, sql_string);
3. v_cursor := DBMS_SQL.OPEN_CURSOR ;
If anyone has been able to perform this type of connection via
OCI or either of the previous 3 methods I listed above, pls
share!

Hi Marion,
MobileMe does not support server side scripting or databases by users.
I have a work around to show the HTML published database with an iFrame if your database app. has instant web publishing capabilities. But that may not be what you are looking for as there will be a 'log-in to database(server)' screen first.
If you are looking for a database driven content management platform then you may want to check out [Drupal|http://drupal.org>, it works with MySQL databases and PHP.
On their website you can find plenty of hosts for your Drupal website.
With PHP or MySQL over ODBC you can even connect to your database.
Check out [DynDNS|http://www.dyndns.com> if you want to use your own Mac as a web/database server behind a consumer router with variable IP nr.
Kind regards,
Leo

There seems to be no defined database cache

Hello, looking at the parameters in this database there appears to be no cache. This shows that AMM is turned off but also that there is no db cache. How is cache being allocate if these are all 0? I am running Oracle 10.2.0.3 on AIX
5300-09. Are there other parameters to look at. Shouldn't db_cache_size be set to something?
sga_max_size ==> 908M
shared_pool_size ==> 252M
db_cache_size ==> 0
db_16k_cache_size ==> 0
db_2k_cache_size ==> 0
db_32k_cache_size ==> 0
db_4k_cache_size ==> 0
db_8k_cache_size ==> 0
sga_target == > 0
I just noticed that this database is using the old method:
db_block_buffers ==> 49152
Should I be setting this to 0 and using db_cache_size instead?
Thank you,
David
Edited by: JesusLuvR on Aug 5, 2009 2:58 PM

Db block buffers would be used to set the buffers within the cache.
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14237/initparams038.htm
You need to find out that why the setting of the db cache size was set to zero? Are you using any setting of VLM(Very Large Datbase) or somethng in your db?

How does oracle i officially /i define b Database /b

<h1>How does oracle <i>officially</i> define <b>Database</b></h1>
There are many definitions I have found on google ( by searching define: database )
how does oracle <i>officially</i> define <b>Database</b>.

From
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14220/intro.htm#sthref11
An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data. All this is accomplished while delivering high performance. A database server also prevents unauthorized access and provides efficient solutions for failure recovery.

MySQL Database Connection (two databases at the same time)

I have never had to open more than one MySQL database from within the same website before, but I do now. The website I have is designed where all the content comes from within the main database. I am building an Inventory system that I want within it's own database, in the event I would ever need to move the application to another server or something, I don't want this data residing in the main database.
Currently, I open the database connection from within a file called "common.php" that resides in a directory called "lib" that can be accessed from the root directory. Below is the proposed code that would be placed within the "common.php" file:
// Define Database Variables
$dbserver = "127.0.0.1";
$dbuser = array('clevelan_user1', 'clevelan_user2');
$dbpass = array('P@ssw0rd', 'P@ssw0rd2');
$dbname = array('clevelan_database1', 'clevelan_database2');
// Start Session
session_start();
// Connect to Databases
connectdb($dbserver, $dbuser[0], $dbpass[0], $dbname[0]);
connectdb2($dbserver, $dbuser[1], $dbpass[1], $dbname[1]);
// Database 1 Connection
function connectdb($dbserver, $dbuser, $dbpass, $dbname) {
// connects to db
global $connection;
$connection = @mysql_connect($dbserver, $dbuser, $dbpass) or die ("could not connect to server");
$db = @mysql_select_db($dbname, $connection) or die ("could not select databsase");
return $connection;
// Database 2 Connection
function connectdb2($dbserver, $dbuser, $dbpass, $dbname) {
// connects to db
global $connection2;
$connection2 = @mysql_connect($dbserver, $dbuser, $dbpass) or die ("could not connect to server");
$db2 = @mysql_select_db($dbname, $connection2) or die ("could not select databsase");
return $connection2;
//End of Code Within the "common.php"
From within any page of the website, I want to access both connections by placing an include at the top of each page:
include_once("lib/common.php");
Currently, when I run the code above, any page within the website (the home page) provides error messages with regards to database connectivity (the pages are looking for there content from within the second database. It's as if the second database is the only database seen by the website.
I need help figuring out how I can have two MySQL databases open at the same time (the second database will only be open for short periods of time and then closed). But the main database is always open.

Create one project using one copy of the exact tables.
create 2 different sessions.xml files each pointing to the same project. Set the login information in the sessions.xml files.
That should work fine.

Database access in JSP?

Can I easily access MS access using JSP? If it is, what kind of drive should be used to access the MS Access database?
Thank you so much!

<%!
// define database parameters

String user="";
String pass="";
String db="";
String conn;

// pass database parameters to JDBC driver
Connection Conn = DriverManager.getConnection(conn);
// query statement
Statement SQLStatement = Conn.createStatement();
This is when accessing a database in a JSP, not a javabean... Try searching this forum, there are LOTS of topics about this.

Usage of GET - Basic LOGICAL database question

Hi,
I have a few doubts in Logical Databases.
1.) Why should i include a logical database in a abap program.
2.) Can i add more than 1 LDB to a abap program
3.) can Nodes statement used on all nodes on LDB
4.) Please provide a example program based on F1S LDB with small explanation.
Thanks in advance,
Bala.

AFAIK, it is expected that we should we the TABLES statement if the node type is a TABLE and if the node type is DDIC type then it is expected that we should use NODES statement, however I found that they can be used interchangeably.
We can find the node type info in the structure defintion of the LDB(in SE36)
Also check this extract from the SAP help
The nodes of the structure are declared with the TABLES statement which generates
the appropriate table work areas. You can also use the NODES statement to define
database tables as nodes. If a node of a logical database is not a database table,
you must use the NODES statement.

Reconstructing a string from a database retrieval

What is the correct way to retrieve data such as a string from a database? If I inputing data to the database like this...
std::string inputString = "hello world";
data.data = &inputString;
data.size = inputString.size();
ret = dbp->put(dbp, NULL, &key, &data, DB_NOOVERWRITE);
and retrieving it like this...
ret = dbp->get(dbp, NULL, &key, &data, 0);
what do I need to do with 'data' to recover my string?
std::string outputString = ??????;
Thanks in advance.

I'm using c++, just didn't realize that there was a db_cxx.h. I still have the same problem though. Here is my test code...
#include <sys/types.h>
#include <stdio.h>
#include <string.h>
#include <db_cxx.h>
#define DATABASE "access.db"
int main()
     Db db(NULL,0);
     int ret;
     db.open(NULL, DATABASE, NULL, DB_BTREE, DB_CREATE, 0);
     std::string KEY = "THE KEY";
     std::string DATA = "THE DATA: A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z";
     Dbt key(&KEY, KEY.length());
     Dbt dataIn(&DATA, DATA.length());
     if((ret = db.put(NULL, &key, &dataIn, DB_NOOVERWRITE)) != 0)
          db.err(ret, "DB->put");
     Dbt dataOut;
     if((ret = db.get(NULL, &key, &dataOut, 0)) != 0)
          db.err(ret, "DB->get");
     std::string outStr = *(std::string *)dataOut.get_data();
     std::cout << outStr.c_str() << std::endl;
     if((ret = db.close(0)) != 0)
          db.err(ret, "DB->close");
     return 0;
If I run this twice, the first time through everything behaves as I believe it should. The database gets created and the output is "THE DATA: A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z". However, the second time I run it, 'put' returns an error due to an existing identical key/data pair (as it should), but the string is just junk as if the pointer is not pointing to the correct memory location. Since 'put' returned the appropriate error message, I expect that the database is fine, and the problem is somewhere in the 'get' function or conversion back to a string. Any ideas?
