I have one PLSQL package that does a join of two tables of remote database instance via the datalink. I just wonder where the most calculation(the join) is done, local machine or remote machine? Is there any best practice to have a better performance for such configuration.
View 3 RepliesI have created a function for knowing the status of link which connect me with remote database.function is as follows
---------------------------------------------------------------------------------------------
CREATE OR REPLACE FUNCTION get_status_db_link (p_db_link_in VARCHAR2)
RETURN NUMBER AS
rows NUMBER;
v_code NUMBER;
v_errm VARCHAR2(64);
[code]....
Now functin should returns 1 when link is up and it should return 0 when link down but sometime when link is down it continues showing executing it hang my pc.
We want to copy a file from a remote machine to the DB server. copy \<IP_ADRESS>SHARED_FOLDERsome_file.sql d:copied_file.sql
I've used Java and a wrapped it into a PL/SQL procedure so I can do :
exec run_os_command(p_command => 'copy \<IP_ADRESS>SHARED_FOLDERsome_file.sql d:copied_file.sql');
The file was not copied.
I have mapped \<IP_ADRESS>SHARED_FOLDER to x: for example and issued : exec run_os_command(p_command => 'copy x:some_file.sql d:copied_file.sql');
The file was not copied.
But when I issued from the OS prompt copy x:some_file.sql d:copied_file.sql then the file is copied.
What can I add to the PL/SQL procedure so it wil work ?

However we are using SE One edition of oracle, so native support for dataguard is not available. There definitely should be some scripting solutions for this task, but I can't find any to date.

Error: ORA-16535: CRS is preventing execution of a broker operation
Oracle Says
Quote:Cause
A broker operation was underway that required CRS to stop managing the instances of this database, but CRS management could not be stopped on behalf of the broker"s request on at least some of the instances, so the broker operation was canceled.Suspend CRS management of this database using SRVCTL STOP DATABASE -D <name> -O NONE. Then reissue the broker request.But this command is not working as it's given to stop the database.
One more thing, it's nowhere said to stop CRS while performing Switchover / Switchback using DG Broker. When we do Switchover / Switchback we keep open only one of the Primary instance.
is there any documentation / link available to switchover of RAC database using dgmgrl (DG Broker)
My application reads a binary file in C++ using fstream.read and needs to save that binary data into the database as a blob.
I am not using OCI.
My struggle is trying to determine the proper way to pass this unstructured data to a PLSQL procedure.
1 > What data type should the input paramter be for the PLSQL procedure?
2 > My binary data is in a char variable. Do I need to convert that to something else before passing it as a parameter.

I have 2 database . One is production and other is Integration and I have one table "emp" which is on integration server and a synonym of that table with the same name"emp" on production. On production we have a proc in which we are using "emp", but some time our integration server goes down, so is there any way to ping the integration server inside the proc and if it returns success then we will execute the rest of code of proc , otherwise it will send a mail to us saying that integration server is down.

View 1 Replies View RelatedI have a simple script which fetch data from another SQL server database.
The remote SQL Server database is accessed by oracle thru gateway, and a simple DB link is made in local database to the remote oracle datbase (which actually access the MS SQL Server)
The SQL script empties all the data in local database, and fills it with the fresh data from MS SQL server.
Problem is sometimes SQL Server is down, and i lose all the data in local database. The script runs automatically as schedualed job. I want to make my script intelligent enough to terminate the script if the other database is down.
I installed oracle 10g and developed simple software using forms 6i. Its working well as a stand alone system.
I want to share it in network. so I installed forms 6i as oracle client , copied the tnsnames.ora from the oracle installation path to forms installation path.(inside NET80/Admin folder)
When i try to connect with user name and password , it comes ORA-12203 Unable to connect to destination. I checked LSNRCTL in the database machine, it is listening.
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:

what changes I need to make to tnsnames and listener at both servers.
As a part of requirement need to clean up some of database objects from database. Before cleaning up need to check for dependencies with in database and also on remote database.

I am using Report Builder 10.1.2.0.2. There is a table in a remote database with synonyms/links defined. I am getting error trying to access those tables. DBA says links/synonyms are correct and I am also able to access that table from SQLTool without error.
I can do a select statement on those tables from 'SQL Query statement' in data model.
Error is generated only if I try to use those tables in 'Formula' or in function/procedure.
I don't know if this is a bug or something else.

I have another terminal opened up to a server at work and I can connect to the DB with sqlplus just fine. I verified that the record for this database on the tnsnames.ora file is the same as it is at work. In conclusion, I can connect to the Database at work, but I cannot at home, even though I am using the same connection information and verified that port 1521 is accessible on this Database server from at home. So why can't I establish a DB connection?
I am newbie to oracle database.
I am using oracle 9i version and in EMCA satndalone application . I have created database links.
The database links have been created, and three databases are local.
When i am pressing the test button in emca . It gives notification database link not active.
What should i do?
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.
