Links in the database

Hi,
I wanted to display links in the database, for example
HTML file
one<br>
two
When i see the result in the browser, i get
one
two
So, now I need the same result in my programme. I wanted to fetch the values from the database and show them to the user and have links added to the values. Can any one help me?
Thanks

If I understand the question there are two parts.
Step 1 - you want to store a url in the database and then get it back out.
Step 2 - you want to display the url in a gui and allow a user to click on it and then display it.
Step 1 is rather easy:
-Create a table named "DisplayLink" with one field name "url". See your database docs for this.
-Populate the table
-Extract from the table using the "select url from DisplayLink". See the jdbc tutorial on this http://java.sun.com/j2se/1.3/docs/guide/jdbc/getstart/GettingStartedTOC.fm.html
- Put the results of the above into an ArrayList and then go to step 2.
Step 2 might be easy or might not. But it doesn't have anything to do with JDBC so you might ask in a GUI forum.

Not able to create a database link using the database gateway of oracle 11g

HI,
While trying to create a database link to SQL server from Oracle ,using the database gateway provided with 11g, i am getting the following error while making use of it in selecting columns from tables :
Error starting at line 1 in command:
select * from test1@dblink
Error at Command Line:1 Column:20
Error report:
SQL Error: ORA-28513: internal error in heterogeneous remote agent
ORA-02063: preceding line from DBLINK
These are the steps i have followed for setting up:
1.Ran the set up for the Database gateway.and mentioned the SQL server name and database .ALos set up a listener.
2. Added the following in the Listener.ora of Oraclehome 11/NETWORK/ADMIN:
LISTENER_SQL_FCD =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =localhost) (PORT = 1541)
SID_LIST_LISTENER_SQL_FCD =
(SID_LIST =
(SID_DESC =
(SID_NAME=dg4msql)
(ORACLE_HOME= D:\app\20537\product\11.1.0\db_3)
(PROGRAM=dg4msql)
3.Added the following in tnsnames.ora inOracle home/NETWORK/ADMIN:
dg4msql=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1541))
(CONNECT_DATA=(SID=dg4msql))
(HS=OK)
4. Following is the entry in initdg4msql.ora in C:\product\11.1.0\tg_5\dg4msql\admin:
HS_FDS_CONNECT_INFO=10.148.45.242:1433//SalesDemo
HS_FDS_TRACE_LEVEL=DEBUG
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
5. Created the database link :
create database link dblink
connect to "sa" identified by "<pswd>"
using 'dg4msql'
On running :select * from test1@dblink i get the following error:
Error starting at line 1 in command:
select * from test1@dblink
Error at Command Line:1 Column:20
Error report:
SQL Error: ORA-28513: internal error in heterogeneous remote agent
ORA-02063: preceding line from DBLINK
Is there any issue with the set or definition that I get the above error?

What is the version of the Oracle database in which you have specified/and use the database link?
If it is for example 10.2.0.3.0 you need to apply the mandatory patch for RDBMS bug 5965763 first before being able to use an 11g gateway. Have a look at MetaLink note 457808.1 for details about this patch.

Ed

Database link between the databases with the same name

Hi,
I need to establish a db link between two databases that are named the same way on two different servers.
server 1 has a database dev1 and server2 has a database dev1. The tnsnames on server2:
DEV1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = server2)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = DEV1)
DEV1_server1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = server1)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = dev1)
Can anyone let me know a way to create a database link between the two above?
Thanks.

Hi,
Am not sure what problem you are facing in creating a db link
create database link dev1_server1 connect to x identified by x using "dev1_server1"
create database link dev1_server2 connect to x identified by x using "dev1_server2"where dev1_server1 and dev2_server2 are the tns entry in tnsnames.ora file of server2 and server1 respectively.

DW CS4 Links to MSSQL Database, sees fields/data but won't display on webpage

I'm trying to get a Dynamic Data Table to show in my webpage but I can't. (Using ASP JavaScript)
I'm using DW CS4 (10.0 build 4117) and connecting to an MSSQL database on a Windows platform server hosted by Verio.
I can successfully link to the database, I can see my data correctly when I bind the record set and do a "Test SQL Statement" , see images below:
My Design View of the page with the table shows the correct fields and looks like:
Everything should look when I switch to Live View or view the page on a browser, right?? Well instead I get this:
If the pic is unclear it says:
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
/Test2009/Untitled-1.asp, line 5
Line 5 of course refers to the ActiveConnection command which uses the INCLUDE file for the connection string.
The Line 5 is
Recordset1_cmd.ActiveConnection = MM_PMCDonSQL_STRING;
And the INCLUDE reverenced is:
var MM_PMCDonSQL_STRING = "dsn=PMCSQL1;uid=pmcapp0010sql;pwd=FloraVista49;"
These are parameters for logging into the MSSQL database (This is just a test database so showing password doesn't matter)":
Server By Name: SQLExpress4.mql14000.MSSQLServers.com,1433\SQLExpress4
Server By IP: 128.121.85.21,1433\SQLExpress4
Database Name: pmcapp0010
Login ID: pmcapp0010sql
Password: FloraVista49
WHAT AM I DOING WRONG?

No one wanted to help me but I figured out that I was not referencing the DSN on the test server, only the local DSN.
The information to connect to the MSSQL database given by my hosting company was not correct for Dreameweaver (or MS Access) either.

Database Link in the OWB

We are trying to deploy a map that needs to use a database link to access the source table in another server. We could create database link on OWB and import tables. When we deployed it we receive the first error "VLD-2771: System privileges may not allow extraction from source PROD_TAX_AVG" and after "table or view does not exists". The privileges was granted and we can test the access in SQLPLUS using the database link created.
Anybody knows this issue ?
Thanks,
Ricardo

Hi Ricardo,
The message "VLD-2771: System privileges may not allow extraction from source PROD_TAX_AVG" is merely a warning, this can (generally) be ignored.
After deploying your mapping check the PL/SQL code deployed and try to identify where the problem is.
I have encountered the issue before where the schema name is configured for the mapping overriding the location defined parameters.
To check this in the Design repository, right-click the mapping and click 'Configure'.
Expand 'Sources and Targets' and check the schema name is not hard-coded.
Cheers.

The Database Link is not active

try to be more clear, i'm in lack of ideas in this problem.
I am following guide Oracle Database 2 Day + Data Replication and Integration Guide.
I defined global_names parameter of remote database as true.In the step of "creation database link" i am getting error.(oracle enterprise manager 11g-->schema-->database links-->create)
When i query on remote database(select * from global_name), I got orcl.
So,In "Name" and "Net service name" field i specified orcl.Check radio button "Fixed user." and Username and password of remote database, and i got message "Database Link STRMADMIN.ORCL has been created successfully."
But when i clicked on database link Name i got error, saying that
"The Database Link is not active.ORA-02084: database name is missing a component "
(Both dbs are oracle 11g.)
Please reply.

I think I am confused, "what should be Name and Net Service Name" while creating database link in context of "Database Replication." when global_names parameter is true in both database. I read somewhere "If the value of the GLOBAL_NAMES initialization parameter is TRUE, then the database link must have the same name as the database to which it connects." so what should database link name " should it be remote database name? db_domain?( or outtput of select * from global_name).......
my tnsnames.ora on source db is
ORCL.a.ernet.in =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = a.b.c.d)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORCL.a.ernet.in)
when i connect user of remote database(a.b.c.d) from sqlpuls then it is connected.
command which i give : sqlplus remoteUser/[email protected]

Database link to the same database

I'm trying to create a database link to the same database.
It doesn't seem to be working ...
basically, the target system will have 2 separate database instances.
I need to emulate this in a single instance database (actually, I don't want to try running 2 oracle instances on my laptop...).
so I want to do select * from fred@MYOTHERDB
when I try and create the alias it succeeds, but then selects don't work.
Lets say my current logon / schema is JOHN (in ORCL) and the other SCHEMA (in ORCL) is JIM
I tried
create public database link MYOTHERDB connect to JIM identified by "Password";
creation worked, couldn't access it.
Thanks in advance

Now I've tried this both from TOAD and from iSQL on the machine with the database.
It's INVMANLAP which I'm using from the TOAD machine, of course!
I appreciate your help. It has been the only bright spark in a DREADFUL day (among other things the IDC-SERVER mentioned above has a trashed system disk which has taken out email and my main oracle server). And I have to install this system tomorrow!

ORA-04054 : using variable substitution for the database link name

Hi,
I need to use variable substitution for the database link name.
Here is my command :

end;
When I run this programm, I receive the error :
ORA-04054: database link REC.OIA_GET_DESIGNATION does not exist
When I replace :

What can I do to resolv my problem ?

What is the name of the DB Link and the name of the object you are selecting
from?
I find it easier to create a view on the remote object then use that in selects.
e.g,
Link Name = MyLink
Object_name = Addr_Loc
create or replace VIEW Rem_Addr_Loc AS
select * from addr_loc@mylink;
In the code I then use the view
begin
for C_Rec in (select * from Rem_Addr_loc)
loop
dbms_output.put_line('Rec: '|| C_Rec.Col1);
end loop;
end;

Can Discoverer have link to display documents stored outside the database?

I posted a message some time ago called "Possible for Discoverer to display BLOB type documents stored in database?" and got great answer.
Now our customers are asking if it is possible, from Discoverer, to link somehow to a file stored outside the database on the Unix file system and get their computer to display it? Can anyone tell me if this is possible please?
The only thing I've seen in the documentation that may be related is in Oracle Business Intelligence Discoverer Configuration Guide, section 10.6 List of Discoverer user preferences. It says there that Discoverer preference ProtocolList can be set so that Discoverer hyperlinks can be set to use protocols such as telnet, but the default is HTTP, HTTPS, and FTP.
THank you in advance if you can help.
Regards,
Julie.

Hi Rod,
I have tried the second method: "create a Oracle directory pointing to the Unix directory containing the files". I have had success with it, but I'd be grateful if you could advise me if you would have done this the same way as described below:
I put two Word docs and two text docs called clob_test1.txt, clob_test2.txt, blob_test1.doc, blob_test2 in the Unix directory corresponding to an Oracle directory called 'EIF'. I thought an extrenal table was needed so that Discoverer would have an object to write a queruy against. So I created a file called lob_test_data.txt with the following contents:
1,01-JAN-2006,text/plain,clob_test1.txt
2,02-JAN-2006,text/plain,clob_test2.txt
3,01-JAN-2006,application/msword,blob_test1.doc
4,02-JAN-2006,application/msword,blob_test2.
THen I created an external table using the following DDL:
CREATE TABLE jum_temp_lob_tab (
file_id NUMBER(10),
date_content DATE,
mime_type VARCHAR2(100),
blob_content BLOB
ORGANIZATION EXTERNAL
TYPE ORACLE_LOADER
DEFAULT DIRECTORY EIF
ACCESS PARAMETERS
RECORDS DELIMITED BY NEWLINE
BADFILE EIF:'lob_tab_%a_%p.bad'
LOGFILE EIF:'lob_tab_%a_%p.log'
FIELDS TERMINATED BY ','
MISSING FIELD VALUES ARE NULL
file_id CHAR(10),
date_content CHAR(11) DATE_FORMAT DATE MASK "DD-MON-YYYY",
mime_type CHAR(100),
blob_filename CHAR(100)
COLUMN TRANSFORMS (blob_content FROM LOBFILE (blob_filename) FROM (EIF) BLOB)
LOCATION ('lob_test_data.txt')
PARALLEL 2
REJECT LIMIT UNLIMITED
then created a Discoverer End User Layer folder against this external table, and used exactly the same technique as we did for downloading the BLOB from the database table (creating a new folder item containing a URL calling a database procedure which calls the Oracle code to download the doc). THis worked, but sometimes my PC didn't seem to know that the Word docs were Word docs and it needed to launch Word. Other times it did manage to do this OK. It always displayed the two .txt files as HTML docs.
Just wondered if you'd be good enough to critique this approach.
THank you, Julie.

How to create a link to a web page that is connected to the database?

Its really hard to answer this question with this enough information....Which Jdeveloper version? which technology you are using to create this web form ? ADF BC or others

When i tried to create the materialized using that DB link.
I am getting the error SQL Error: ORA-00942: table or view does not exist.
Can anyone please find the root cause and provide the solution for this?

The relationships and links between the various SAP database tables

Hi Gurus,
I am trying to learn the relationships and links between the various SAP database tables (SAP FI-AA, SAP SD, SAP MM, SAP HR and so on) for correctly extracting data from them. Especially I am expressing an interest in the SAP database tables on SAP FI-AA, SAP SD, SAP MM, SAP HR. Could somebody provide me with documentations about the relationships and links between them. I will be very grateful if somebody can provide me with links.
Thanks and regards

Failed to retrieve data from the database/invalid argument provided when employing link between two web services datasources

Post Author: vpost
CA Forum: Data Connectivity and SQL
I am trying to join information from two related web services within CR XI. I have successfully set up the web services as data sources have been able to get to the point where I get good data back. However, when I try to pull in certain fields, I get an error that says "Failed to retrieve data from the database/invalid argument provided". Here's the scenario:
The web services are structured as follows:Web Service 1 (Artist) has attributes of Artist Name and Date of Birth.Web Service 2 (CD) has attributes of CD Title and Release Date. Underneath each CD are songs, each of which have a Song Title and Artist Name.
I have defined both web services and defined a link between Artist.Artist Name and CD/Song.Artist Name. I am able to run a report with Song Title and Date of Birth that crosses web services. I am able to run another report with Song Title and CD Title that crosses the different levels in the second web service. However, if I add CD Title to the first report or Date of Birth to the second (both of which effectively force CR to employ the link between the two web services AND the CD/Song hierarchical structure in the second web service, I get the aforementioned error.
Any assistance understanding how multiple web services can be linked in this manner would be greatly appreciated.
Thanks in advance.

Not sure about your exact situation, but having similar problem with another application and have tracked down to security. Added user to group Domain Admin and it works fine. It appears to be accessing a subdirectory which it does not have permission to use and then times out and returns the "invalid....". Seems that once the query just over a certain size (and I'm not sure what triggers this) it needs to make use of temparory file disk, intead of ram.
I'm still trying to track down which temporary it's trying to uses - so if you have any ques.

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]

Odbc connection test success but can't link the database to oracle with 1013 call failed error.

i am using my MS Access 2013 to connect with my oracle database. I created the odbc link and successfully have connection test pass. However i can;t link the database with my MS access. When i am using different software (mapinfo), i am able to connect to oracle database. The error is"1013: user requested cancel of current operation"

In MS access, i open the external data and select odbc. Select my odbc link created previously, enter the password and after a while the error message pop up.
But if i am using another tools, such as SQL Developer or Mapinfo, i will able to connect to oracle database using the same odbc link.
