Warning  2010-12-06 03:34:56.680757 12202 1 Activation: Cannot replicate overflow table for an IOT. Skipping ("OWNER"."NAME")  (activating sid source_SID) [module ocf]

Shareplex does not support some IOT options depending on Shareplex and Oracle version.

First check the section “Supported and Non-Supported Operations” in the Shareplex Release Notes for the Shareplex version in question for support of IOT. Then check the database and Shareplex version for the IOT option in question.  If the IOT option is not supported for that Shareplex/Oracle combination, then take the table(s) out of the config file and activate the config file again.
