How to execute remote query by Oracle Database Link

I use Oracle Database Link to query data from SQL Server. The query is like:
select *
from tableA@DL_SqlServer a
join tableB@DL_SqlServer b
on a.ID = b.ID*
tableA and tableB is large and the result is relatively small. This query executes quickly in SQL Server since indexes are built both on the two tables. But it is very slow on Oracle Database Link to SQL Server.
I guess the join operation is performed on Oracle side not on SQL Server side, thus the indexes are not used. Since I just need the joined result, I prefer to perform the query entirely on SQL Server and get the small result only. But I have no privilege to create views on SQL Sevrer.
I konw that using SQL Server's linked server and OPENQUERY function can achieve this goal. I wonder how to do this on Oracle Database Link. Thanks!

DO NOT DO THIS....specifically:
"select *
from tableA@DL_SqlServer a
join tableB@DL_SqlServer b
on a.ID = b.ID*"
You would be better off to do the following:
create a Materialized View in Oracle and once/day (or as frequently as you feel necessary) pull the data from SQLServer and then do the join locally by creating MV as TABLEA_MV and TABLEB_MV and then have views that have the REALTABLEA and REALTABLEB names that point to these MVs. This can be done without recompiling or changing your code. Trust me, I have seen this sort of thing in the past that completely crippled an IBM mainframe using DB2 along with a major network segment by having this sort of join via DB links. You must understand the ramifications of your "design" and I can tell you for certain that it is a very BAD!!! idea... Fix this before you are issuing another command: "alter DBA update resume/CV;"
The app went into production at 7AM. By 9:30AM, the mainframe had executed more than 10Billion I/O's. It took > 15hrs for the mainframe to recover once we shutdown the app and implemented the view/MV described above.
I will leave it as an excercise for the OP to develop the syntax for this.

Variable database name in SQL Server query using Oracle database link

Hi All,
I have an ApEx 4.1 app running on 11g x64 (11.2.0.1) on Windows Server 2008 x64, and I have some data integration points with a SQL Server (2005 and 2008) that I need to establish. I have configured the database link with dg4odbc and it works beautifully... I can execute queries against the SQL Server database without any problems using the database link.
However, there is a scenario where the SQL Server database name is dynamic, and I need to generate it on the fly in a PL/SQL block, and then use that in a dynamic SQL query (all of this in ApEx). This is where I run into problems... when I am querying the default database based on the ODBC connection and I don't have to specify the database name, there is no issue. But when I need to access one of several other non-default databases, I keep receiving the "invalid table" error.
This runs fine:* (note that "fv" is the name of my database link)
v_query1 := 'select "ReleaseDate" from dbo.Schedules@fv where dbo.Schedules."SchedID" = :schedule';
EXECUTE IMMEDIATE v_query1 into rel_date using schedule;
I then take that rel_date variable, convert to a varchar2 (rel_date_char), and then use it as the database name in the next query...
This returns an error_ (Error ORA-00903: invalid table name)
v_query2 := 'select "PARTNO" from :rel_date_char.dbo.ProdDetails@fv where "SchedID" = :schedule and "UnitID" = :unit
and "MasterKey" = :master and "ParentKey" = :parent';
EXECUTE IMMEDIATE v_query2 into part_number using schedule, unit, master, parent;
I have also tried using all of the following to no avail:
'select "PARTNO" from ' || :rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from ' || rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from ' || @rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from @rel_date_char.dbo.ProdDetails@fv where "SchedID"...
Is there a way to do this in PL/SQL?
Thanks for any help!

=> instead of executing the statement using "execute Immediate" we have to use PASTHROUGH package to pass the statement to the SQL Server.

How can I connect to an oracle database remotely using telnet in DIAdem?

I need to query an oracle database on a remote server and store the result back in DIAdem. Does anyone know how to telnet through diadem and return the result?

DIAdem provides you with tools to connect to databases using SQL. Specifically, you can use SQL_Connect to open a connection to a database through a DSN (Data Source Name). The DSN has to be configured on the local machine (Control Panel -> Administrative Tools - > Data Sources) and has to point to the remote Database. You can map a network drive in the local machine so you can browse to your remote Database. The DSN will provide the link between DIAdem and the remote Database.
If your communication has to be throught telnet, then I suggest you try to use an ActiveX control. VBScript doesn't support Telnet natively, but it does support ActiveX controls. You can create one from Visual Basic or try to find a telnet client that has one already.

Can execut a query in Oracle UCM to get View_Values instead of using GET_SC

Dear All,
i have a question that i had google it and didn't find anything helpful.
i want to ask if i can execut a query in Oracle UCM to get View_Values instead of using GET_SCHEMA_VIEW_VLAUES service ?
ie: asuume that we have a Table name called Employees (having empId, empName) and have a view named as Table name; Employees.
instead of use the GET_SCHEMA_VIEW_VLAUES service to get the data of Employees, can i write a query, ex: select from Employees*_ to get the data.
note: i have a connection parameter to connect to oracle UCM database
any suggestions.
Regards

Yes, you can execute the query and store results into a result set (available also in iDocScript).
There are two sample components that you could use as a starting point - see here http://www.oracle.com/technetwork/middleware/webcenter/content/howtocomponentsbundle-132171.zip or here for 11g http://bexhuff.com/2011/03/howto-component-samples-for-oracle-ucm-11g
Take a look at DataAccess and DatabaseProvider from the sample stack.

Thanks In Advance
Shoeb Ahmad

Hello,
You first need to add new SQL DB connection then you need execute connection from code behind.
See below link to create new connection
http://office.microsoft.com/en-in/infopath-help/add-a-data-connection-to-a-microsoft-sql-server-database-HP010092823.aspx:
http://www.bizsupportonline.net/infopath2010/connect-infopath-2010-sql-server-2008-table.htm
Then use below code to execute this connection:
AdoQueryConnection conn = (AdoQueryConnection)(this.DataConnections["Data connection name"]);
string origCommand = Select * from tablename;
conn.Command = origCommand;
conn.Execute();
Finally bind your table:

Query in timesten taking more time than query in oracle database

Hi,
Can anyone please explain me why query in timesten taking more time
than query in oracle database.
I am mentioning in detail what are my settings and what have I done
step by step.........
1.This is the table I created in Oracle datababase
(Oracle Database 10g Enterprise Edition Release 10.2.0.1.0)...
CREATE TABLE student (
id NUMBER(9) primary keY ,
first_name VARCHAR2(10),
last_name VARCHAR2(10)
2.THIS IS THE ANONYMOUS BLOCK I USE TO
POPULATE THE STUDENT TABLE(TOTAL 2599999 ROWS)...
declare
firstname varchar2(12);
lastname varchar2(12);
catt number(9);
begin
for cntr in 1..2599999 loop
firstname:=(cntr+8)||'f';
lastname:=(cntr+2)||'l';
if cntr like '%9999' then
dbms_output.put_line(cntr);
end if;
insert into student values(cntr,firstname, lastname);
end loop;
end;
3. MY DSN IS SET THE FOLLWING WAY..

5.THEN I CREATE THE READ ONLY CACHE GROUP AND LOAD IT
create readonly cache group rc_student autorefresh
interval 5 seconds from student
(id int not null primary key, first_name varchar2(10), last_name varchar2(10));
load cache group rc_student commit every 100 rows;
6.NOW I CAN ACCESS THE TABLES FROM TIMESTEN AND PERFORM THE QUERY
I SET THE TIMING..
command>TIMING 1;
consider this query now..
Command> select * from student where first_name='2155666f';

Execution time (SQLPrepare) = 0.074964 seconds.
The command failed.
Command> SELECT * FROM STUDENT where first_name='2093434f';
< 2093426, 2093434f, 2093428l >
1 row found.
Execution time (SQLExecute + Fetch Loop) = 0.585897 seconds.
Command>
7.NOW I PERFORM THE SIMILAR QUERIES FROM SQLPLUS...
SQL> SELECT * FROM STUDENT WHERE FIRST_NAME='1498671f';
ID FIRST_NAME LAST_NAME
1498663 1498671f 1498665l
Elapsed: 00:00:00.15
Can anyone please explain me why query in timesten taking more time
that query in oracle database.

How to I convert data from oracle database into excel sheet

how to I convert data from oracle database into excel sheet.
I need to import columns and there datas from oracle database to microsoft excel sheet.
Please let me know the different ways for doing this.
Thanks.

asktom.oracle.com has an excellent article on writing a PL/SQL procedure that dumps data to an Excel spreadsheet-- search for 'Excel' and it'll come up.
You can also use your favorite connection protocol (ODBC, OLE DB, etc) to connect from Excel to Oracle and pull the data out that way.

How I enable network service of Oracle database 10g XE ?

Hi,
How I enable network service of Oracle database 10g XE ?
Following error occurs when printing:
ORA-20001: The printing engine could not be reached because either
the URL specified is incorrect or a proxy URL needs to be specified.

ORA-20001 is a user defined error. So you will have to find out where it comes from.

Error executing a query using a DB-Link

Hi all,
I'm trying to execute a query on a DB using a connection. I created a DB-LINK on the DB. executing the select:
select sysdate from dual@lnk_db_prod;
I get the following error:
Error starting at line 1 in command:
select sysdate from dual@lnk_db_prod
Error at Command Line:1 Column:19
Error report:
SQL Error: ORA-01882: timezone region not found
ORA-02063: preceding line from lnk_db_prod
The error will be return executing any query on a db-link.
It appens if I create a db-link using syntax referencing the SID and using the sintax with the complete connection string. Below the two example of db-link DDL commands:
1.
CREATE DATABASE LINK lnk_db_prod
CONNECT TO prod IDENTIFIED BY prod
USING 'DBPROD';
2.
create database link lnk_db_prod2
connect to prod
identified by prod
using '(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(PROTOCOL = TCP)
(Host = 10.41.54.156)
(Port = 1521)
(CONNECT_DATA = (SID = DBPROD)
Can you help me, please?
bye,
Ivan

Hi,
You would be better off posting / searching on other Oracle forums that deal more specifically with Application Servers. I googled "WebLogic set time_zone" and the first three hits were from our forums:
Default TimeZone
How to fix msg=ORA-01882: timezone region not found
http://kr.forums.oracle.com/forums/thread.jspa?messageID=9400587
I hope one of the these is what you are looking for.

(2) Set tnsnames.ora for connecting to AS400/DB2.
(3) Create database link
http://download-west.oracle.com/docs/html/A97615_01/toc.htm
Another of that
