In Oracle 10gR2.If a materialized view uses a database link for the query in order to create a snapshot of data on a remote instance, does the name of the database link have to be an entry in the tnsnames.ora file?
The following link suggests not, but is not version specific: Materialized View - Oracle Wiki FAQ
However, the following 11g documentation suggests that the database link name must be the same as the global name of the target database.URL.. I can't any info specific to 10gR2.
We have three instances. Our application metadata is stored in a schema in B.METADATA. There is a shell schema (B.METADATASHLL) that provides access to the tables to remote applications.
On instance A, we have a shell schema (A.METADATASHLL) that creates materialized views as follows: CREATE DATABASE LINK METADATA_PRIME CONNECT TO metadatashll IDENTIFIED BY password USING 'B';
Our materialized view is created using the query SELECT * FROM METADATA.APPLICATIONS@METADATA_PRIME WHERE Application = 'A';
The query works, but the materialized view does not.I'm being told that the database link has to be named B as follows
CREATE DATABASE LINK B CONNECT TO metadatashll IDENTIFIED BY password USING 'B';
Which means that I can only have one public link to instance B, and I'm in a pickle if I create a second application (which I have) using the same model).
From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?
we have the following requirement for creating materialized view.
In database "DB1", a table "abc" is there in "user1" schema. In database "DB2", in "user2", we are accessing the "abc" through DB link "DBL1" to DB1: select * from user1.abc@DBL1; we have created a public synonym for "user1.abc@DBL1" as "sabc".
In database "DB3", we need to create the materialized view to access "abc" in DB1 through DB2. we are not allowed to access "DB1" directly from "DB3". so we create a db link as "DBL2" in "DB3" to "DB2".
when i try to create a materialized view as below: create materialized view abc_mv as select * from sabc@DBL2;
But got the error as "synonym translation invalid". When i access the SQL statement separately as below select * from sabc@DBL2, its working but in Materialized view, it shown that error. Even i tried with schema name as well like "user2.sabc@DBL2" , but that also thrown same error.
Is there any option available for this type of creating materialized view?
Holiday_master table has the list of holiday dates as "From_Date"
I have the form based on the Leave_Transaction Table, and I have created the Process, as "On-submit-after computations and validations" and posted the following PLSQL code,
declare days number(3); ex_days emp_master.remaining_days%type; new_rem_days emp_master.remaining_days%type; begin
[code]....
If the Dates is between from_date and To_date comes in Saturday and sunday and/or if any Date is exist in the Hpliday_master table it will exclude and return the count(*) remaining dates, For example,
If the From_date is 04-may-2012' and To_date is 08-may-2012,
Here the dates 5th may and 6th may are "saturday" and "sunday"
and if any date between From_date and To_date is exist in Holiday_Master Table i.e say here it is 07-may-2012, Then the remaining dates are(excluding sat,sunday and dates in holiday_table),
04-may-2012, 08-may-2012.
so the count(*) is 2.
I am using the above code but still it returning 5,I think this
...where to_char(dt,'fmday') not in ('sunday','saturday') minus (select holiday_start from holiday_master))

Is it possible to use Database authentication in APEX through database link, and how?Also is it posible to read roles from users through database link?
FRM-40501: ORACLE error: unable to reserve record for update or delete.
ORA-24374: define not done before fetch or execute and fetch
My master-detail form has single canvas. For both blocks, master and detail, two tables joined together in each. One table to be updated, second table has some info for reference (query only).
I am getting these errors when in detail block the item from LOV is selected for existing record. This does not happen for new record inserted in detail block.
On my APEX page i have region which has sql query as source and it displays as HTML table the query result to the user.
I want to display addinonal column with a hyperlink inside, and that hyperlink would have CGI/URL-parameters which contains the other values of the HTML row.
So, let's say my APEX region queryes columns as "select c1, c2, c3, c4 ..." and displays out values "V1, V2, V3, V4" then i want to have addional output column with such hyperlink:
a href="f?p=100:7:13467554876288::NO::c1,c2,c3,c4:v1,v2,v3,v4">My link column with CGI-parameters</aHow can i create such hyperlink?
The overall idea is that the link would forward to a page which loads those values "v1,v2,v3,v4" into form fields and user can proceed from there.
I want to pass multiple column values of a row in an interactive report page to hidden items in another page through column link. And I did it successfully. However, I found I need to pass more than 3 columns of a row in this report, while a column link only permits me to pass 3 column value at most. Is there anyway that I can pass more column values to hidden items in another page?
I am trying to create a database link from the 11g database to the 10g database using: create database link ORCL10R2 connect to <username10g> identified by <password10g> using <db10g>;
It Returns Database link created.
select sysdate from dual@ORCL10R2 returns error: ERROR at line 1: ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA
what changes I need to make to tnsnames and listener at both servers.
i am having database in server and i have to run my web application in client machine. how to set the connection of server database in web.config file.
A procedure in a package uses a database link. The database link is defined without a username and a password. The user that uses the database link is supposed to be present in the opposite database as wel.
When the procedure is started in SQL*Plus or TOAD it runs perfect. But the procedure has to run in a scheduled job. And that doesn't work. The procedure fails because of: ORA-01017 invalid username/password. The user that is used to run the scheduled job is the right one.
I have installed oracle database 11gr2 in laptop1 and installed oracle database 11gr2 in laptop2.Both the laptop's are connected to same internet connection through wifi. So my question is can i create a database link between these two databases using this wifi? give some steps in creation of a database link.
i need access to a view running on another database server. i configured my db link and tried to compile the view. but the following message occurs: ora-12154: TNS: Connection Identifier..
I would like INSERT data in a VIEW with a INNER JOIN, like this example:
CODECREATE VIEW MYVIEW (order_id,list_price,customer_id) AS SELECT order_id, list_price, customer_id FROM ORDERS o INNER JOIN PRODUCT_INFO p ON (o.order_id= p.pdt_id);
INSERT INTO MYVIEW VALUES (4,500,10); /* will cause an error*/
But when I try to execute the insert statement, the "SQL Developer" returns a error:
ORA-01779 - "cannot modify a column which maps to a non key-preserved".
I found a link to a topic concerning this issue (click here), but the question mentions that the poster was looking for a "band-aid" fix...if this method will work for a more long-term solution
Usually where should we create the database link? In the production or development? create public database link dblinkname connect to user_in_db2 identified by password_in_db2 using 'tnsentry name in db2'; In production or development?
