Since I already wrote a blog post listing a list of resources for Oracle Endeca Information Discovery, I figured it would be good to do the same for the Oracle Endeca Commerce (Experience Manager).
Official Oracle resources
OTN Technical Questions Forum
The official forum for people having technical questions. Use the search feature when you have an issue, you will surely find someone that had a similar problem.
https://community.oracle.com/community/oracle-applications/endeca_experience_management/technical_questions
Documentation Index
Full documentation for Endeca Commerce in PDF and all related modules
http://www.oracle.com/technetwork/indexes/documentation/endecaguidedsearch-1552767.html
Oracle Endeca Community
Official discussion support forum limited to people having access to Oracle Support (you will need a login access to Oracle Support). Less questions than the OTN Technical Questions but still a lot of relevant informations available.
You can also have access to the Knowledge Base which include articles written by the members of the Oracle Support team that relates to common bugs and problems encountered by the various clients.
