Logs and Error Handling Codes
To help diagnose problems, you need to be thoroughly familiar with the key Windchill ESI logs, described in the Windchill Enterprise Systems Integration Installation and Configuration Guide - Oracle Applications. You also need to be familiar with the EAI error-handling architecture, and the error codes. The following lists the available logs and how to access them:
Logs
How to Access
Windchill Enterprise Systems Transaction Log
Windchill PDMLink user interface

Windchill ESI application messages appear with a role designation of ESI to distinguish them from the standard TIBCO product messages.
TIBCO BusinessWorks Administrator. You can find the log files at <TIBCO_HOME>/tra/domain/<domain_name>/application/logs/<Application_Name>-Process_Archive.log[.sequence#]
TIBCO EMS logs
File name and path are determined by log file related configuration parameters in the tibemsd.conf file.
TIBCO Adapter for Oracle Applications logs
<TIBCO_HOME>/tra/domain/<domain_name>/application/logs/<Application_Name>-ESIOMAdapter.log.[.sequence#]
Oracle Applications logs
Consult your Oracle Applications administrator.
You should also be familiar with the Oracle Applications distribution targets and the data objects and attributes impacted by Windchill ESI. You may have direct responsibility for viewing and manipulating data in Oracle Applications, or may simply have to coordinate these activities with Oracle Applications administrators. To view the data that was transferred into Oracle Applications by Windchill ESI, the following windows are particularly important:
Master Item
Bills of Materials
Engineering Change Orders
Routings
