Improvements with 11.1 for the datatypes and table structures supported for asynchronous change data capture option

Filed under: Oracle 11g New Features — H.Tonguç Yılmaz @ 9:25 am

I was studying the Asynchronous Autolog CDC Cookbook, I am working on the S_AUDIT_READ Siebel source table, but the AUDIT_LOG column with CLOB datatype failed during the setup with ORA-31513: unsupported column type specified in change table error on 10.2.

As I found out that this limitation for LOBs is not a problem after 11.1 anymore, I wanted to share this information.
