Card Puncher Data Processing

Prerequisites for Installing DAC

Prerequisites for installing the DAC Client and Server on Windows are the following:

  • Download the file Oracle Business Intelligence Data Warehouse Administration Console v10. on OTN
  • Create a repository user which will store the dac object

For instance, for Oracle :

DEFAULT tablespace users
TEMPORARY tablespace temp
quota unlimited ON users;

GRANT connect, resource, create view TO DAC_REP;

DAC Configuration Handled by the DAC Installer

The DAC installer handles the following configuration:

  • In the config.bat file, the DAC installer configures the JAVA_HOME and DAC_HOME variables.
  • In the dac_env.bat file, the DAC installer creates an environment variable named INFA_DOMAINS_FILE and sets the value to the directory path of the domans.infa file.
  • The DAC installer adds the directory path to Informatica PowerCenter binaries to the PATH environment variable.

If you reinstall or upgrade Informatica PowerCenter without reinstalling DAC, you need to manually set these environment variables.


The explanation of the installation are minimal and don't say all details as for instance that you have to hit the Next button.

  • Unzip the dac downloaded file
  • Start the installation with the dac\Disk1\setup.exe
  • Install location : C:\orahome\10gR3_1
  • Choose informatica 8x or 7x. For Informatica 8.1.1 or 8.6.1, you have to choose 8.x
  • Informatica 8x location :
    • Informatica Powercenter : C:\Informatica\PowerCenter8.x.x\server
    • Informatica PowerCenter Domain File : C:\Informatica\PowerCenter8.x.x\domains.infa
  • Prerequisite check : Ok.

Installation of the last patch 10052370.

  • extract the content of the file p10052370_101341_Generic.zip
  • Terminate all DAC clients and server(s).
  • Rename the jar file DAC_BASE\bifoundation\dac\DAWSystem.jar as DWASystem.jar.old
  • Rename the xml file DAC_BASE\bifoundation\dac\conf\infa_command.xml as infa_command.xml.old
  • Copy the patched up DAWSystem.jar file into DAC home directory (DAC_BASE\bifoundation\dac\)
  • Copy the patched up infa_command.xml file into DAC_BASE\bifoundation\dac\conf\

JDBC Driver

DAC requires JDBC drivers for database connectivity. To enable DAC database connectivity, you must install the appropriate JDBC driver in the dac\lib directory on the machines where the DAC Client and Server are installed.

To install JDBC drivers in the \dac\lib directory, copy the file corresponding to your database version from the directory oracle_database_home\jdbc\lib directory and paste it in the ORACLE_DAC_HOME\bifoundation\dac\lib directory.

  • For Oracle database 11g, ojdbc6.jar
  • For Oracle database 9.x or 10.x, ojdbc14.jar
