Generate query at a time & connect two database ?

Hi
Could u help me? it is necessary that
I have two database ( RSHPL,RSPL) and both data base have same table name and same fieldname (Table Name :-OITM, Fieldname :ONHAND ,pk- ITEMcode,)
At first I tell u what I want?
I want to generate query at a time & connect two database and same table name(OITM) to select the TOTAL VALUE of this field(ONHAND) and pk-key is Itemcode.
Is it Possible? If Possible plz write this query and send me.

Hi,
I don't think its possible to write a query from within SAP that allows you to get data from another SAP database.
I have used SQL Reporting Services to report on data from multiple databases, and this works very well for many of my clients. It depends on what you want to do with the data, do you need to display it on the screen in SAP and it to a field or will a report suffice?

Adrian

Configure remote DB in TNS first.
Create DB link.
CREATE {PUBLIC} DATABASE LINK "DBLINKNAME" CONNECT TO "remoteuser" IDENTIFIED BY "remotepwd" USING 'REMOTEDBTNSALIAS';Query remote tables using
select * from remotetable@DBLINKNAME;

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.

Connect two database in runtime

I have a application, which will set the JDBC connection once the tomcat load. Then i can get the connection each time. But there are another function in the application, which will insert some data into another database. But I don't know how to load two database connection once the tomcat load or switch to another database base. Thanks for you help.
In the context.xml. the current setting as belows
<?xml version="1.0" encoding="UTF-8"?>
<Context reloadable="true" path="/">
<Resource auth="Container"
               driverClassName="oracle.jdbc.OracleDriver"
               maxActive="15"
               maxIdle="60"
               maxWait="8000"
               name="jdbc/dbdatasource"
               username="xxx"
               password="xxx"
               type="javax.sql.DataSource"
               url="jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.100.1)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.100.2(PORT = 1521))(LOAD_BALANCE = yes))(CONNECT_DATA =(SERVICE_NAME = toc)))"/>
</Context>
And when the application get connection, will use the following coding.
db = new DBAccess(this.getClass());
public DBAccess(Class sInClass) throws Exception{
sCallerClassName = sInClass.getName();
connectDB();
private void connectDB() throws Exception{
String sDbName;
String sDbUser;
String sDbPasswd;
          try {
          Context initCtx = new InitialContext();
          Context envCtx = (Context) initCtx.lookup("java:comp/env");
          DataSource ds = (DataSource) envCtx.lookup("jdbc/dbdatasource");
          this.oCon = ds.getConnection();
oSystemLog.debug(" ----- Class " + sCallerClassName + " connection started ----- ");
} catch (Exception e) {
oSystemLog.error("",e);
throw e;
}

Configure another Resource entry with a different JNDI name (yours is called "jdbc/dbdatasource") in Tomcat and create a corresponding mapping in your web application's deployment descriptor (the web.xml file).

Same query takes different time for two different users with same privileges

Hi,
Just wanted to know if it is possible for an INSERT query to take different amount of time for two different users for the same volume of data. If so, what could be the reason? I would like to add that we are not executing the query simultaneously. But it is always faster for user1(within 10-20 seconds) and slower for user2(takes around 8-10 minutes).

Show execution plan for each user. I think there is other reasons which you didn't not tell

Connecting Two database

I have two Database. One the master databse is Oracle 7.3 and another Oracle 8.06. Now i want to update a field in Oracle 8.06 from Oracle 7.3. These updation also has to be done for the new records created. How i can do.

May be using create database link!

CVI Error : After more than 2000 times connect to database.

Dear all:
After connect to the database more than 2000 times ,CVI shows below error,( I also used the DBdiscoected to free system resources )
It seems out of memory, but when I checked the memory usage with resource track , memory leak is not found .
and the physical memory of PC is enough .
All of your advice is appreciated.
Tks

Hi -
I just setup an ran a simple program which connected and disconnected from a databse 2500 times without error. My program was simply a loop around DBConnect and DBDisconnect, checking for errors after each call.
Please tell us more about your system. What version of CVI are you using? Also, what is your OS? How many connections do you have open at a time?
Also, from your screenshot, I see that it mentions "Native error code -2147024882". According to this KnowledgeBase article, native error code messages mean that an error occurred in the database itself, and the code is being passed back to CVI to be handled. From a quick google search on this error code, it appears to mean "Not Enough Storage is available to complete this operation".
If you are able to condense your code into a version that we can run, which reproduces the error, you can post it and we'll take a look at it. Also, I would recommend looking more into the -2147024882 error in regard to the database that you are using.

Hyperion- Can it Connect to two database at a time

Hi All,
I am new to Hyperion Reporting and Analysis. Kindly help me in the following Scenario.
Consider two database 'A' and 'B'
I want to create a report from tables from Database "A" and "B"
How to do that.
Kindly Help me out
Thanks in advance
Regards
Gatha

For Interactive Reporting there are a couple options.
1. Us the OBIEE BI Server and model your semantic layer with the connections. The Product is designed for Federated Queries.
2. Build within Client
- Query 1 for Database A
- Query 2 for Database B
- Qyery 3 using local results build the data model from Query Results A and B - Joined appropriately
3. Depending on the Database - SQLServer, Oracle, DB2 etc you could connect to multiple DB within one OCE - You will need to look at Mark Ostroff's tips and tricks guide from previous Hyperion Conference for how to do it.
Hope this is Helpful

Query all applications that are connected to database in the current time

Dears,
I need to query all applications that are connected to database in the current time. I tried using v$session but i could not reach through it to the application that are logged now to database.
As example, i connect to DB through Web Application and tried to search in v$session to can see Web Application session but i did not see it :(
From searching in google, found that there is a package named "DBMS_APPLICATION_INFO". I expected that it can help me in my request but i could not use it.
Please, advise me. Is this package help cover my requirements or there is another method ?

Can you have two connections to database

I am running two java programs which access the same database. One runs forever, and keeps the same connection up. The other program, lets say does a simple update, but it stalls and will never do the update. If I kill the first programs connection, then the second program can do the update. I am using the jdbc thin client. Is there a way I can have these both run and not stall?

The short answer is, yes.
There are two general approaches to the problem. The first approach is to use various locking, commit and rollback techniques. The basic premise is that if program A runs into a problem, the database drops A and reverts back to the previous state before responding to program B. This is highly dependent upon the database you're actually using, and probably beyond the scope of this forum.
The second approach is to code your programs with a philosophy of "get in, do it, get out" as quickly as possible. In other words, do NOT leave a database connection open if you can avoid it.
Essentially your program makes a connection, does a select query, copies the results into a data structure you define, and exits. Then you're free to play with the results as you see fit. When the time comes to do an update, you make the connection, perform the update, then immediately exit. If you need to test it, make another connection, do a select on that record, copy it, close the connection, then compare the copy with what you anticipate.
There is the added benefit that whenever you close the connection, most databases will then do whatever commits need to be done, and release any deadlocks that may be in place.
Your problem isn't really that your database cannot do two connections - its the fact that your database does not want to let two separate people make changes to the same table at the same time. There's an obvious reason for it and we can go into more detail if you want.
But essentially, if you do each transaction as quickly as possible, and let the database clean up after each transaction, you will avoid most, if not all of the problems you're experiencing.
Don't worry about the overhead of creating and closing connections. If it does become a problem, you can always use a "Connection Pool" (search for it on the forums if you want to know more). You just don't want to be in a position where the database is saying "I can't give you the info you want because I don't know if this other program is going to change any of it before giving control back to me."

Taking too much time (1min) to connect to database

Hi,
I have oracle 10.2 and 10g application server.
Its taking too much time to connect to database through application (on browser). The connection through sqlplus is fine.
Please share your experience.

Dear AnaTech,
i am going to ask not related this question which already you answered i am going to ask you about that how to connect forms6i and Developer 10g with OracleAS.
i have installed and working Developer Suite 10g Ver. 10.1.2 and also Form Builder 6i. On my other machine i installed and working Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 and also on the database machine i installed Oracle Enterprise Manager 10g Application Server Control 10.1.2.0.2.
my database conectivity with Developer suite Forms and Reports and also Form6i and Reports6i are working fine. no problem.
now the 1 question of mine is that when i try to run form6i through run from web i got this error. FRM-99999: error 18121 occured see the release not.
this and the main question of mine is this that how can i control my OracleAS 10g with forms because basically the functionality of OracleAS is Mid-Tier but i am not utilizing the Mid-tier i am using here Two-tier Envrionment even i installed 3-Tier Environment so tell me how i utilize it with 3-Tier..
I hope you don't mind that i ask this question here and also if you give me you email then we can discuss this in detail and i can be helpful of your great expertise. i also know and utilize my 3-tier real envrionment.
Waiting for your great response.

If we observe test query is very simple and easy to back track but in Dev it is appending like sawwith0,sawwith1 etc..looking difficult.
Is there in any configuration to change to generate query like Test(with out SAWWITH0).
NOTE:Any how results are same in both instances.
Please help me to resolve this issue.
Thank You,
Anil Kumar.

Anil,
Are your database settings the same in both of the rpds dev and test?
Check wether you didn't change anything to the default. Open your RDP double click on the Database in the physical layer and go to Feature you can check all the settings there
