Using database link with a dynamic SQL in Forms 5

I have a Form 5 application where a database link is specified in a client version of dynamic SQL. The function that the application is designed to perform is to access data in a table in a remote database and use it to populate another table in a local database with the same structure as the source table. Dynamic SQL is used because the name of the table can only be resolved during run time.
The problem is that it gives error with code 'ORA-03113' and text 'End-of-file on communication channel' when you try to run it.
Is it not possible to use a database link with a dynamic SQL? What can I do to overcome the problem ?

Try to create a local view based ao the remote table and use the view.

DATABASE LINK with GROUP BY SQL Statemnets

We have Oracle Database Link linked to MySQL . We want to force executing remote statement that contains group by on the remote MySQL server and let MySQL do the aggregation instead of Oracle.
We tried also DRIVING_SITE but it doesn't help and the query that was sent to MySQL from Oracle DB Link didn't include GROUP BY and it looks like that the Group by was executed on the local Oracle.
Is there a way for force executing GROUP BY statements on remote DB instead of the local Oracle DB?

Using database links in a plsql page process

I am trying to use a database link in a pl/sql page process.
It works fine when I use the link name in the plsql like this:
BEGIN
SELECT
CARD_ID
into
:P12_HDR_CARD_NUMBER
from     [email protected];
But the link name will be coming from a page item (P12_DBLINK) populated as follows:
select db_link d, db_link r from user_db_links;
I have tried the following and it's not working:
DECLARE
l_link VARCHAR2(30);
BEGIN
l_link := :P12_DBLINK;
SELECT
CARD_ID
into
:P12_HDR_CARD_NUMBER
from     fusion.EXM_CC_COMPANY_ACCOUNTS@l_link;
this gives me:
ORA-04052: error occurred when looking up remote object FUSION.EXM_CC_COMPANY_ACCOUNTS@L_LINK.WORLD ORA-00604: error occurred at recursive SQL level 3 ORA-02019: connection description for remote database not found
I thought that maybe the link name was getting appended with .WORLD automatically but the link name already has .WORLD at the end. I tried stripping that off first but the error is the same.
Is there some synatx for this that will work for this? Will I need to use dynamic sql?
Any suggestions are most appreciated.
thanks,
john

Adding user to the oracle database using database link - is it possible?

Hi, i wolud like to manage my databases using one client. I easilly operate on my distriubuted tables but i have problem with creating users in distribiuted database. Is it possible to create users in distributed database using database links? or it have to be done locally using some stored procedures or sth similar?

The SQL syntax of the CREATE USER statement doesn't support DB links, the only way to do it would be with stored procedures. There might be an Oracle SP for that or for generic remote execution of SQL, but I'm not familiar with such.

Creation of database link from oracle to sql server 2000

Hi
I need to create a database link from oracle to sql server 2000.

Assuming your Oracle database is running on Windows, you can set up a database link using ODBC using Heterogeneous Services and Generic Connectivity, but there are some functional limitations (i.e. no two-phase commits). If you can live with those limitations but aren't on Windows, you can generally purchase an ODBC driver for your operating system that will connect to SQL Server through someone like DataDirect and still use Generic Connectivity. If you cannot live with those limitations, you can purchase one of Oracle's Transparent Gateway products (though this can get somewhat pricey).
What version of Oracle are you on?
What operating system(s) are you using?
What are you going to use the database link for?

Creating Database Link from Oracle to SQL Server

I am trying to create a database link from Oracle to SQL Server, and the documentation is about as clear as mud to me. Can anyone send me clear instructions on exactly what I need to do? What needs to be in tnsnames.ora and listener.ora files? Is there anything other than those two files that needs to be set up? Do I set up an ODBC connection? Anything else? I want to execute queries against a SQL Server database and load data into Oracle database.
Thanks so much,
Susan

These are the instructions from an old document I created. The steps are same for SQL Server and Sybase. Hope it helps.
The 9i Transparent Gateway Software is in Oracle Software CD -> oracle9i database -> Custom -> Oracle Transparent Gateways
The gateway can be installed on the same machine as the Oracle database or
on the Sybase server or on a third machine as a stand-alone.
We have installed the gateway software in one of oracle database
servers in a separate oracle home.
These are the steps involved in configuring a gateway to a Sybase database
1.     Install Sybase client and Gateway software on the Gateway Server
2.     Configure <initsidfile> in the Gateway Server's <gatewayhome>
     /u00/app/oracle/product/9.2.0/tg4sybs/admin/init<gatewaysid>.ora
Sybase server and database information is required for this step.
eg: HS_FDS_CONNECT_INFO=USTRUD01.uwd
3.     Add an entry in listener.ora in <listnenerhome>
     (/u00/app/oracle/product/9.0.1/network/admin/listener.ora) for the <gatewaysid>
4.     Edit the tnsnames file (/u00/app/oracle/product/9.0.1/network/admin/tnsnames.ora)
to add an entry <tnsalias> for the <gatewaysid>
5.     Create a database link to the Sybase database in the oracle database.
The steps for creating the database link are
a. create a login oracle_tgw in the sybase server
b. add the user to the sybase database with the necessary privilege on the tables
c. create the database link in the required oracle database using the command
     "create public database link <dblinkname> connect to oracle_tgw identified by password using 'tnsalias'; "
6.     Restart the gateway listener.

Thanks,

Thanks for Everyone,
I was struggle with this almost 10 days....
I created Database link from Oracle to SQL Server
Now it is fine.........
Here i am giving my servers configuration and proceedure how i created the db link...@
Using Generic Connectivity (HSODBC) we can create db link between Oracle and SQL server.
Machine (1)
DB Version : Oracle 9.2.0.7.0
Operating System : HP-UX Itanuim 64 11.23
IP : 192.168.0.31
Host : abcdbt
Machine (2)
Version : SQL Server 2005
Operating System : Windows server 2003 x86
IP : 192.168.0.175
Host : SQLDEV1
User/PW : sa/abc@123! (Connect to database)
Database : SQLTEST (exsisting)
Table : T (“ T “ is the table existing in SQLTEST database with 10 rows)
Prerequisites in Machine (2):
a)     Oracle 10g software
b)     User account to access SQL Server database (sa/abc@123!)
c)     Existing SQL Server Database (SQLTEST)
d) Tables (testing purpose) (T)
Steps:
1)     Install Oracle 10.2.0.1 (Only SW,No need of database) *(Machine 2)*
2)     Create a DSN where your windows Oracle 10g SW resides *(Machine 2)*
Control panel >> Administrative Tools >> Data Source (ODBC) >> System DSN ADD
You can follow this link also.....
http://www.databasejournal.com/features/oracle/article.php/3442661/Making-a-Connection-from-Oracle-to-SQL-Server.htm
I created DSN as
DSN name : SQLTEST
User : SA/abc@123! (Existing user account)
Host : 192.168.0.175 (machine 2)
Already I have 1 database in SQL Server with the name SQLTEST
You can create DSN with different name also (not same as db name also)
3)     Create a hsodbc init file in $ORACLE_HOME\hs\admin *(Machine 2)*
Create init<DSN NAME> file
Ex: initSQLTEST
Copy inithsodbc to initSQLTEST
And edit
initSQLTEST file
HS_FDS_CONNECT_INFO = SQLTEST    <DSN NAME>*
HS_FDS_TRACE_LEVEL = OFF*
save the file....@
4)     Configure Listener.ora *(Machine 2)*
LISTENER_NEW =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
SID_LIST_LISTENER_NEW =

(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = extproc) )
:> lsnrctl start LISTENER_NEW
5)     Configure tnsname.ora *(Machine 2)*
SQLTEST11 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SQLTEST))
(HS=OK)
:> tnsping SQLTEST11
If No errors then conti….
6)     Configure a file *(Machine 1)*
Cd $TNS_ADMIN ($ORACLE_HOME/network/admin)
Create a file
$ vi TEST_abcdbt_ifile.ora
something=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST =192.168.0.175) (PORT=1525))
(CONNECT_DATA=

Database link with the alias and full description in the connect string

Hi,
i have created database link with alias in tnsentry and full description
and suppose i have removed the tnsnames.ora file what will be the impact on the database link that is whether database link will work or not i am sure db link created with alias won't work and how about db link created with full description and which one you prefer
Thanks

# Parameter file initora for Database prd
### Global database name is db_name.db_domain
global_names = TRUE
db_name = prd
db_domain = world
# TNSNAMES.ORA for prd ###############################
prd.world = (DESCRIPTION = (ADDRESS = (COMMUNITY = tcp.world)
(PROTOCOL = TCP) (Host = 100.10.100.1) (Port = 1521))
(CONNECT_DATA = (SID = prd) (GLOBAL_NAME = prd.world)
(SERVER = DEDICATED)))
Our database link points from the local database test to the remote database prd. Therefore we need the global database name for prd. Ask the remote database administrator for these information or connect to prd and execute the following query on prd:
SQL> select GLOBAL_NAME from GLOBAL_NAME;
GLOBAL_NAME
prd.WORLD
CREATE DATABASE LINK prd
CONNECT TO system IDENTIFIED BY system_passwd
USING 'prd';--- alias
so the connection description will be ---select ename from [email protected]

TNS-12666 error occures when using database link

When I am trying to use database link
defined in my database the following error occures:
TNS-12666 Dedicated server: outbound transport protocol different from inbound.
In documentation is stated to resolve such an error to
specify the same protocol in the SQL*Net connect string or alias for the outbound connection as that used for the inbound connection.
I have in tnsnames.ora defined network service name
by which I can connect to such a database by SQL*Plus
without any problems, why can I not do such a thing
via database link?
Thanks a lot for advise, ...

Could you change the following entry in your 'sqlnet.ora' file and try?

How to Execute a Remote Procedure in Portal using Database Link

Hi,
I followed the instructions to create a Portal form for a remote procedure. But I am encountering the following error. Can someone advise what may be the cause?
Failed to execute - Missing string(create_package_body) language(us) domain (wwv) sub_domain (wwv_builder) (WWV-04300)
ORA-04020: deadlock detected while trying to lock object PUBLIC.PORTLET_SCHEMA (WWV-11230)
Failed to parse as PORTAL - (WWV-08300)
PURPOSE
How to execute a remote procedure in Portal using Database Link.
DESCRIPTION
This procedure assumes that you have two databases, one of which is remote, and Portal is configured in the other.
Remote Database A:
==================
1) Create a procedure as follows: Create or Replace PROCEDURE SCOTT.ADD_TWO_VALUES ( v_one IN NUMBER, v_two IN NUMBER, v_result OUT NUMBER) as begin v_result :=v_one+v_two; end; 2) Grant execute privileges to PUBLIC on the procedure.
Database B (where Portal is configured): ========================================
1) Create a public database link and choose to connect as a specific user (say SYSTEM). By default, in an Oracle 8i database, the "global_names" parameter in initSID.ora (or init.ora) file is set to "true". This Global Naming parameter enforces that a dblink has the same name as the database it connects to. Therefore, if the remote global database (A) name is "ora8.acme.com" then the database link should also be named as "ora8.acme.com".
2) Create a synonym for the procedure in Database A. Make sure you fully qualify the procedure name in the remote database (like SCOTT.ADD_TWO_VALUES).
3) Create a dynamic page to execute the procedure. The ORACLE tags in the dynamic page will look similar to the following: <ORACLE> DECLARE v_total NUMBER; BEGIN ADD_TWO_VALUES(:v_one,:v_two, v_total); htp.p('The total is => '); htp.p('<input type="TEXT" VALUE='||v_total||'>'); htp.para; htp.anchor('http://<machine.domain:port#>/pls/portal30/SCOTT.DYN_ADD_TWO_VALUES.show_parms', 'Re-Execute Procedure'); END; </ORACLE>
4) Portal does not have an option to create a form based on a synonym. Therefore, if you want to create a form instead of a dynamic page, create a wrapper procedure and then create a form based on this procedure. For example: Create or Replace PROCEDURE PORTAL30.ADD_TWO_VALUES_PR ( v_one IN NUMBER, v_two IN NUMBER, v_total OUT NUMBER) as begin add_two_values(v_one, v_two, v_total); end;
5) Grant execute privileges to PUBLIC on the procedure.

How to use database link in from6i?

I can use database link in sql plus,but i can't use it in forms6i,why? thanks

Don't know why.
What I always do is create a synonym on the local database which points (through the db link) to the object on the other database.

What is the problem with native dynamic sql when counting rows in all table

Usually your problem can be described with 'Who cares'. I mean, for what reason do you do this? I doubt that there's a business need to get 100 % accurate answers for this. Normally such things are used to get a picture about the growth of data.
Personally I would prefer to have up-to-date statistics for all tables and just query the number of rows from there. Sufficient for me in < 99 % of all cases.

Git/gitHub supported or can used together (linked) with dreamweaver cs6

git/gitHub supported or can used together (linked) with dreamweaver cs6? what is version control?
server folder, web url fields,...when define a LOCAL HOST SERVER what must insert? I have XAMPP...htdocs/ win7...?

It is best to download scripts from Github and save them in your local site folder.
To set-up a local testing server in DW see screenshots below. Replace C:\wamp\www\ with xampp\htdocs
Make sure Xampp is running.
