Replicating UDDs

To create the datatype requires Replication Server administrator privileges or granted permission.

1. Log in to the RSSD.

2. Add a row to the rs_datatype table using the following example as a guide:

   /*  rs_oracle_udd_raw - char with no delimiters */
   insert into rs_datatype values(
   0,                   /* prsid */
   0x0000000001000008,  /* classid */
   'rs_oracle_udd',     /* name */
   0x0000000000010210,  /* dtid */
   0,                   /* base_coltype */
   255,                 /* length */
   0,                   /* status */
   1,                   /* length_err_act */
   'CHAR',              /* mask */
   0,                   /* scale */
   0,                   /* default_len */
   '',                  /* default_val */
   0,                   /*-delim_pre_len-*/
   '',                  /* delim_pre */
   0,                   /*-delim_post_len-*/
   '',                  /* delim_post */
   0,                   /* min_boundary_len */
   '',                  /* min_boundary */
   3,                   /* min_boundary_err_act */
   0,                   /* max_boundary_len */
   '',                  /* max_boundary_err_act */
   0                    /* rowtype */
   )
   go
   

3. You must restart Replication Server after adding a new type.

4. In Replication Server, test the new type:

   admin translate, 'The quick brown fox jumped over the lazy dog.', 'char(255)', 'rs_oracle_udd'
   

   go
   

   Delimiter Prefix   Translated                  Value Delimiter Postfix
   

   ----------------------------------------------------------------------
   

   NULL               The quick brown fox jumped over the lazy dog.  NULL
   

The new type has been defined correctly if the sentence was translated correctly.

The following example demonstrates how to create a replication definition, using the rs_char_raw type defined in Replication Server. The following Oracle table and type definitions are used in the example:

• Oracle UDD object type name: NAME_T

• Oracle table name: USE_NAME_T

• Oracle table columns: PKEY INT, PNAME NAME_T

create replication definition use_name_t_repdef
with primary at ra_source_db.ra_source_ds
with all tables named 'USE_NAME_T'
(
   PKEY int,
   PNAME rs_rs_char_raw
)
primary key (PKEY)
searchable columns (PKEY)
go
