Updates to tables that include either java or user-defined data types are not synchronized after Adaptive Servers in high availability system are configured as primary and secondary companion servers. For example, if a table in the pubs2 database on the primary companion stores java objects as column data, updates to this column are not propagated to the proxy table. Instead, you must manually update any changes made to columns that store user-defined data types.
And, for another example, if your pubs2 database on the primary companion includes a table that uses user-defined data types, the pubs2 proxy table on the secondary companion does not include any updates that you made to pubs2 on the primary companion.
