SQL & PL/SQL :: Create Trigger Which Will Test Database Link?
Aug 29, 2012
I want to create a database trigger which will test the database link, if it is ok then it will use dblink and do its work.
If it fails then it will send the data into its own server logfile.
I Wrote:
CREATE OR REPLACE TRIGGER PERMIT.TESTTRG
AFTER INSERT OR UPDATE
ON PERMIT.TR_LP_M_H_COMPANY_25072012
REFERENCING NEW AS New OLD AS Old
FOR EACH ROW
Declare
l number; nIgn PLS_INTEGER; nRows PLS_INTEGER := 0;
[code]....
When I execute it it is giving error:
LINE/COL ERROR
-------- -----------------------------------------------------------------
4/11 PLS-00201: identifier 'EXEC_SQL.CONNTYPE' must be declared
4/11 PL/SQL: Item ignored
8/2 PLS-00320: the declaration of the type of this expression is
incomplete or malformed
create or replace view test_view as select 1 id,CONTRACT_REF_NO,chg_gl from test union all
[code]...
11 rows selected.
I have done only for one id.
so the problem is the front end is showing this test_view that people will modify.but they have to actually modify the table ,so I can think of an instead of trigger(instead of insert and instead of update ones).
create table test123 as (unit varchar2(5),qty varchar2(25)); insert into test123('ABC','10,40,50'); insert into test123('PQR','20,30,40,10'); insert into test123('XYZ','20,10,70');
I have a table called test123 which qty field. if the sum of qty is entered more than 100 or less than 100, it should throw error.
I wrote this trigger..but it is not working.
create or replace restrict_sum after insert or update of qty on test123 for each row declare v_sum number; [code].........
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?
on my Windows 7 machine with Oracle Client 12.0.1.0 installed I'm trying to create a database link to a database server, that runs under Oracle Standard Edition1 11.2.0.2. When i login to sqlplus on the client with "sqlplus /nolog" and type the command : SQL> create database link SID connect to user identified by passwd using 'tnsnames.ora connection'; I'm getting an SP2-0640: not logged in.
Ok, thats clear, because i use sqlplus with /nolog option. But on client side normally I have no database, where I can login. So I think, there will be no user, or? The database to which I want to connect is set in tnsnames.ora. Generally: Is it possible to use the Oracle Client to create a database link?
Which Privileges required to create a trigger like after logon on database. I have grant Create any trigger privilege to user but still not able to create and give me an error insufficient Privilege.
I created an report and made it accessible as Restfull server. When I checked the url, I got an XML back. So the service is working.
As test I wanted to create a webservice reference to that same page, but receive ORA-06502 PL/SQL: numeric or value error: hex to raw conversion error whenever I test the service. I tried all kind of options.
Settings: URL ........... HTTP MEthod : GET Parameters app page reportid (and even parmvalues, lang, output) outputformat : XML
When I test this service I receive above error. I use Apex 4.1
we have a production database 'X'. Now i have created a test database 'T' and did'nt configured another listener to it! The issue is when i cam connecting to oracle through sqlplus i am directly connecting to Test database 'T' but not the production database 'X'----ofcourse i can login to production DB afterwards. but initially i want to access the production database 'X'.
I need to refresh a PROD database into TEST database. The PROD and TEST runs on 10g. I need a full refresh. Is there any pre req's which i should keep in mind ?.

I have a script that creates all db links for a schema. The script currently has hardcoded password use to create db link. We do not want to hardcoded password in the script.
I am planning to manually ask to input the password using accept command in sqlplus but this may be time consuming because there are many db links. So, I wanted to know if there are any better options ? Is there any way to use encrypted password in the sql file?
i've perform a stress test of a database in 2 configuration :
1) Single instance 11.2 with 8gb Sga e 4gb Pga on Linux, 6core with instance caging =4, resource_manager=defaut_plan
2) 2 Nodes Rac 11.2 with 8gb Sga e 4gb Pga in both nodes on Linux, 32core with instance caging =4, resource_manager=defaut_plan.
I've used Swingbench and the transaction per minute are equal, Avg transaction per s in rac are Greater then single instance (4ms vs 40ms).I know that rac is not for high performance.My question is: is rac config best than single instance and if yes what is the %?
I have to migrate the current production database to test 10.2.0.4 on windows. Any non-export way to upgrade 9i to 10 g?
i have following steps
1) ALTER DATABASE BACKUP CONTROLFILE TO TRACE 2) shutdown oracle 9i database on server A 3) copy database file, controlfile, redolog, and other files to new server B 4) alter the controlfile backup with new location of bdump, udump, and log file and data file locations 5) user oradim ORADIM -NEW -SID SID [-INTPWD PASSWORD ]-MAXUSERS USERS -STARTMODE AUTO -PFILE ORACLE_HOME\DATABASE\INITSID.ORA 6) start dabase in upgrade mode 7) run catpat.sql and util102.sql 8) take backup 9) open database for users
I Have an apex page that display a modal window utilizing jquery. In the modal window I have a classic report with a link column that I want to capture its click event.
I was thinking I could create a dynamic action with selection type=jquery selector. Not for sure if I need to do anything on link column and do not know the syntax jquery selector.

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?
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.
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..
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).
