The following error is observed during activation when trying to activate a nested table:
Error 2009-05-07 19:50:16.362823 29718 1 Activation: Activation on nested table columns not allowed. id=155585 (OWNER.TABLENAME) (activating sid SID_name) [module osp]
Nested tables are not supported in Shareplex at the time of writing of this solution.
Identify and remove such nested tables from the config file prior to activating the file. Then activate again. Otherwise the activation will not be successful.
The Shareplex Admin Guide Chapter titled "Shareplex Replication" section " What SharePlex does not replicate" delves on what is excluded. The list is updated as and when new objects, datatypes, features are included in supported list.
Also see SOL52332 for some other useful information regarding interpretation of supported and non-supported features.
