The following script can help determine if the tables in your schema contain unsupported datatypes:

Section
Column
width5%

 

Column
width95
Panel
bgColorCCC
Prompt Specify owner for the tables that you want to replicate
Prompt Specify table_name(s) for the tables that you want to replicate. % for all.
select owner, table_name, column_name, data_type 
from sys.dba_tab_cols 
where data_type not in (
 'NUMBER',
 'FLOAT',
 'VARCHAR2',
 'VARCHAR',
 'CHAR',
 'NVARCHAR2',
 'NCHAR',
 'NCHAR2',
 'LONG',
 'LONG RAW',
 'DATE',
 'RAW',
 'BFILE',
 'CLOB',
 'BLOB',
 'NCLOB'
)
and data_type not like 'INTERVAL%'
and data_type not like 'TIMESTAMP%'
and owner = upper('&owner')
and table_name like upper('&table_name');

select owner, table_name, column_name

  • Some SECUREFILE LOBs operations (see below)
  • 32K VARCHAR (Oracle 12.1)
  • identity columns (Oracle 12c)

 

*TIMESTAMP with TIMEZONE expressed as offsets are supported.

 If SOURCE tables are created & configured with Oracle Basic Compress option (including at the tablespace level) replication is unsupported for these objects.

A SQL query can be run to determine if there are any datatypes that will not be supported by Dbvisit Replicate.
