On this post we will discuss all the steps necessary to ensure you have the correct version of the OPatch patching utility for oracle software running on your system. If you find this post useful please or Share our site!

Environment Variables:

Set your ORACLE_INSTANCE path to a valid OBIEE 11g instance

Set your ORACLE_HOME path to the OBIEE 11g home (Oracle_BI1)

Validating Your Environment:

OPatch is installed by default, locate it go to the ORACLE_HOME path for your OBIEE installation:

\Oracle_BI1\OPatch

To verify your current session is correctly configured verify the installed version by running the following command:

opatch version

Minimum Required Versions:

OBIEE 11.1.1.5.0 -> OPatch version 11.1.0.8.3 or higher (do NOT use OPatch 12.x)

OBIEE 11.1.1.6.0 -> No OPatch packages available as of March 12, 2012

Downloading a Newer Version of OPatch:

To find and download the appropriate version of OPatch for yor system please go to ORacle Support and find the knoledge base article below:

Note 224346.1 – Opatch – Where Can I Find the Latest Version of Opatch?

Installing OPatch:

To install OPatch once you have downloaded the appropriate version follow the steps below:

  1. Rename your current OPatch directory (ORACLE_HOME\OPatch)
  2. Copy the zip file to your ORACLE_HOME
  3. Unzip the zip file
  4. Verify that the upgrade succeeded

    cd OPatch
    opatch version

File System Access:

OPatch will update the local Oracle Inventory so the user account running OPatch must have acces to the location of the OUI Inventory, to verify this you can run the following command:

opatch -lsinventory

Patch Directory Location (PATCH_TOP):

If you have a centralized location where you store code / releases it is a good idea to create a directory called PATCH_TOP to store patches as they are applied to each environment (DEV, QA, STAGE, PRD).

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

ODI Error: ora-00001–unique constraint ( pk_pop ) violated

Posted on by admin

SYMPTOM:

 

image_thumb1

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

Posted on by admin

SYMPTOM:

image

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.

Real Time Operational Business Intelligence with GoldenGate

Posted on by admin

Oracle Golden Gate ArchitectureOracle Corporation’ (ORCL) acquisition of Golden Gate Software on July of 2009 was a big step for Oracle in its quest to build a open and heterogeneous product line that will be more appealing to enterprise customers with complex OLTP and data warehouse environments. You can find a detailed presentation of the considerations that were taken into consideration regarding this acquisition here. In the data warehousing space this is a welcome addition to the earlier acquisition of Sunopsis (now Oracle Data Integrator) a Extract-Load-Transform alternative to traditional ETL tools such as Informatica and IBM Information Server (DataStage) that plays nice in heterogeneous database environments and is significantly easier to use, and more stable than the displaced Oracle Warehouse Builder (OWB). Key areas where Golden Gate can be of use in a heterogeneous database environment:

  • Simplifying disaster recovery by maintaining near-real time copies of transactional databases
  • Change Data Capture and extraction and staging for data warehouse environments
  • Real-Time operational business intelligence by means of a message queue and a Business Activity Monitoring (BAM) or Business Process Management (BPM) solution

 

Under the last scenario events can be fed into real time alerts or dashboard Key Performance Indicator’s in real time in addition to triggering additional events when the event is orchestrated via an enterprise bus. Here’s a link to a step by step installation and configuration demo at Oracle Technology Network (OTN). Stay tunned for additional product reviews and OBIEE tips and tricks that are coming soon and check my review of Oracle Data Integrator here..
