Supported DDL Operations for Oracle Sources

Supported DDL Operations for Oracle Sources

The Extractor for Oracle sources can process the following DDL operations:
  • ALTER TABLE

     AS SELECT
    statement
  • DROP INDEX
    index_name
  • DROP TABLE
    table_name
  • TRUNCATE TABLE
    table_name
  • To replicate CREATE TABLE and CREATE INDEX operations from Oracle 12
    c
     sources, ensure that the _ORACLE_SCRIPT parameter is set to false for the Data Replication session that includes the Oracle source. To set this parameter to false, execute the following SQL statement: 
    ALTER SESSION SET _ORACLE_SCRIPT=false;
  • For replication configurations that have an Oracle source and target, Data Replication can replicate index-organized tables (IOTs) to identical IOTs. However, if you have a target type other than Oracle, Data Replication replicates IOTs to regular target tables.
  • Data Replication does not replicate CREATE TABLE ... AS SELECT statements that create IOTs.
  • Data Replication does not replicate CREATE TABLE...AS SELECT * FROM operations if the replicated table contains LOB data.
  • Data Replication does not replicate function-based indexes or function-based default values.
  • Data Replication does not replicate indexes that are associated with a constraint. Data Replication replicates constraints without the associated index.
  • Data Replication does not replicate the ENCRYPT keyword for Oracle source columns. On the target, Data Replication creates corresponding columns without the ENCRYPT keyword.
  • Data Replication does not replicate temporary tables.
  • Data Replication does not replicate CREATE INDEX operations that create an index in a schema that is different from the schema of the indexed table.
  • Data Replication does not replicate DROP INDEX operations that drop an index in a schema that is different from the schema of the indexed table.
  • Data Replication does not replicate the SECUREFILE option when processing ADD COLUMN operations for LOB columns.
