Recently digging into the strategy and best practice of installing the OBIEE Applications, mainly the DAC and Informatica components, I see two common issues arise more often that any others. One has to do with the Informatica Integration Service not matching the correct locale such at UTF-8 or MS Windows Latin, etc. preventing it from starting and the other has to do with the Informatica or DAC user not able to call the core integration tools pmrep and pmcmd. This issue is common on Linux/Unix environments but not so much on a Windows server environment.
