Configuring the windows host file to correctly use the loopback adapter for Oracle product installations

Posted on by admin

This procedure is required when installing Oracle products such at the Oracle Database or Oracle Business Intelligence Enterprise Edition on a host machine that uses DHCP.  Follow the steps to configure a loopback adapterand then:

  1. Open the host file under c:\windows\system32\drivers\etc using notepad
  2. Identify your computer’s host name by right clicking on My Computer, selecting properties and clicking on the computer name tab Identify your computers host name by right clicking on My Computer, selecting properties and clicking on the computer name tab
  3. On the first line of your host file add a link between the static IP address you assigned your loopback adapter and your computer’s host name, for example: # IP                 hostname.domain        hostname 10.10.10.35    virtualXP.acme.com virtualXP
  4. On the second line associate the same static IP with the localhost default alias, for example: 10.10.10.35 localhost.localdomain    localhost

Once you have completed these steps you can proceed with the next steps in your Oracle product installation. If you find this post useful please or Share our site!

odi-10182: Uncategorized exception during repository access

ora-00001: unique constraint ( pk_pop ) violated

 

CAUSE:

 

There is another interface with the same name on the repository.  Interface names are unique and independent of their folder location. In my case I had an interface with the same on a different folder.

 

SOLUTION:

 

Rename or delete your duplicate interface.

Error: ora-00001: unique constraint ( pk_txt_header ) violated

odi-10182: Uncategorized exception during repository access

ora-00001: unique constraint ( pk_txt_header) violated

 

CAUSE:

The table definition was created by duplicating metadata for another table. Indexes are defined as constraints in ODI, when duplicating the original table object the index definitions are duplicated with the original names, for some reason this does not trigger an error at the time of duplicating the tables, the primary key validation for the index name is triggered –in my case- at the time of saving a mapping where the table duplicate is a target.

 

SOLUTION:

On Design > Models look up the duplicate table. Once located review and update the names of each of the constraints / indexes defined on metadata and save them. Once you have completed the review you should be able to save the mapping throwing the original issue message.

Sunopsis seven years after it’s acquisition

Oracle Data IntegratorOn October of 2006 Oracle acquired Sunopsis a sofware company whose flagship product was one of the up-and-coming players in the datata warehousing arena. Sunopsis for easy integration in environments with multiple database systems and differentiated itself by adopting an Extract-Load-Transform architecture that decreased the learning curve for database developers that were immediately able to create transformation using familiar SQL syntax. By utilizing the computing power in the target database Sunopsis’ ELT architecture potentially decreased the need for additional computing power in a dedicated ETL server. Fast forward five years and Sunopsis is now Oracle Data Integrator, it is a key component of the Fusion Middleware Data Integration product line and it’s looking good, a few features that large enterprise customers will find interesting are:

  • SOA enabled an can deploy and consume web services for data transformation and integration
  • Integrates well into your data cleansing (names, addresses) and Master Data Management framework
  • Out of the box CDC functionality with a Publish-and-Subscribe model implemented either via triggers or log mining (Oracle and DB2)
  • As previously stated, by utilizing the source and target database’s computing power ODI decreases it Total Cost of Ownership (TCO)

It seems as if the merging of Oracle Warehouse Builder and Sunopsis’ functionalities has been beneficial to the end product and, in general, to the enterprise customer. Now it remains to be seen how aggressively Oracle”s sales force can take market share from ODI’s top competitors IBM Information Server and Informatica PowerCenter.
