Hi There,
Nice Article on Materialized Views. I am working on Oracle Incentive Compensation as a technical person. My responsibility is to interface the transaction data to incentive module to calculate commission. Compensation will be calcuated every month. I have developed a PL/SQL program to extract transactions every month to put the transactions in the staging area where incentive module picks up the data from the staging table. This is the basic overview of my work.

The problem i am facing is for every month there are about 6 million transactions needs to be send to the staging table. It is a nightmare if i use the PL/SQL program to load the staging table. For this situation, can i use materialized view instead of using the PL/SQL program to load the staging table? Any help greatly appreciated..

Hello Dina

Materialized Views are in the materialized view site. At the Replicated site. In my example it’s the same DB as the Master DB, because I used a loopback DB link in my example. In real life you have a master site (tables and snapshot logs) and a replication site (materialized views).

Hallo Stefan

You are right. I learned about the sc (service control) windows shell command only recently at my new job. Thanks for pointing out.

Hallo Mahesh The steps describe a materialized view replication (not bi-directional) within a single database. You get an error when trying to create a database link from instance r5dev10g to itself. You need a loopback database link. Use this syntax: CREATE DATABASE LINK instance.kt.lunet.ch@instance CONNECT TO user IDENTIFIED BY password USING ‘instance’; Did it work?

Hey, I thought that the steps provided here which i can use for my scenario. It is like,

I want to setup replication using Mviews within a database.

The steps provided here seems, similar to my requirement. So, started implementing it. But while creating DB Link I faced an issue.

SQL> CREATE DATABASE LINK R5DEV10G.AIG.COM CONNECT TO gens1 IDENTIFIED BY gens1 USING ‘R5DEV10G.AIG.COM’;
CREATE DATABASE LINK R5DEV10G.AIG.COM CONNECT TO gens1 IDENTIFIED BY gens1 USING ‘R5DEV10G.AIG.COM’
*
ERROR at line 1:
ORA-02082: a loopback database link must have a connection qualifier

As i am quite new to MView, I am not for sure how to resolve it and tried my level best to find the solution finally I opened ticket to Oracle to get some help.

Now, as per oracle support, I skipped dblink creation step and created Mview. Now, getting new error as below while creating index
SQL> CREATE INDEX indx_mv_objecttype ON TESTMV(gens2.emp);
CREATE INDEX indx_mv_objecttype ON TESTMV(gens2.emp)
*
ERROR at line 1:
ORA-00904: “GENS2″.”EMP”: invalid identifier

Tell me onething,
1. is this steps for Mview replication within a database ?
2. Is this replication bi-directional replication (replicate each other) ?

Do you have any clue if i am wrong anywhere !?

That is definitely not the recommended way. To delete a service use the command line tool sc. For instance

sc delete OracleServiceORCL
