Linked server DTS issue

Hi need help, I am using Linked server to connect to a oracle server and transferring the data to the local tables, it is working fine if the join transaction is not selected, if we select it it fails with the following error: "MSDASQL was unable to run distributed transaction", the join transaction unit is required as I need to rollback the deletion of data from the tables in the first step of package. Any help will be appreciated. Transaction coordinator is running.My Oracle knowledge is pretty thin but I am betting the MSDTC does not work with Oracle. I would google it.
