Distribution Target Prerequisites and Assumptions
As part of your implementation planning and before installing Windchill Enterprise Systems Integration, you need to be aware of the assumptions made for the distribution target and then perform the prerequisite configurations.
* 
Windchill Enterprise Systems Integration may not function as expected on Oracle Applications distribution targets that do not match the criteria listed in this section. In some cases, applying the relevant Oracle Applications patches or upgrades might be sufficient to update the Oracle Applications distribution target to perform the expected functions. In other cases, the distribution targets must be classified as unsupported.
