The following functionality is currently not supported, but maybe supported in future:
- XMLType.
- Table cluster related DDL.
- IOTs (index-organized tables).
- Switchover/failover/flashback.
- Non-standard redo log block size (including 4k on 11gR2 on Advanced Format disks).
- Object datatypes (includes ADT, VARRAY, nested tables etc.).
- Only English version is available. Different languages will be supported in the future.
- No support for compression or encrypted data (Transparent Data Encryption TDE).
Known limitation:
- Dbvisit Replicate relies on the target database client settings for handling of NLS issues. For an Oracle target database, set the NLS_LANG environment variable to "AMERICAN_AMERICA.source_db_charset". The AMERICAN_AMERICA part ensures unified number and date formats and specifying the source database charset ensures that the client libraries handle any non-ASCII characters properly.
