ORA-25341
sync_capture does not support "string"."string" because of the following reason:
Cause
sync_capture encountered a table with an unsupported property. The most common reason is an unsupported column data type.
Action
Revise the Capture rules to skip over the table in question. One option is to remove the rule that captures changes from the unsupported table. Check DBA_STREAMS_TABLE_RULES to determine the rule on the table specified in the error.
Also query the DBA_STREAMS_UNSUPPORTED view to determine which tables are not supported by STREAMS and for what reason.
For potential workarounds to certain unsupported properties, see Metalink.
