Oracle Database

Overview

Semarchy xDI allows to work with Oracle Database to produce fully customized Data Flows.

Third-party libraries

Due to licensing restrictions, we cannot distribute the Java libraries for this database. You must obtain them yourself.

After you have the necessary Oracle libraries, create a Oracle module for your project, and add the libraries to the module.

Supported Features

Common Features

Feature	Description
Reverse	Metadata can be reverse engineered.
DDL/DML Operations	DML/DDL operations can be performed on the database, such as: Insert, Update, Select, Delete, Create or Drop.
Integration Methods	Append Incremental Update
Load Methods	Generic Load Oracle SQL*Loader External tables Database Link (Oracle to Oracle)
Staging Methods	This technology can be used as a staging to make data transformation, mutualization, and more. The following methods are supported: Staging as Sub-Query Staging as View Staging as Table
Rejects	Reject rules can be defined to filter or detect data that does not fulfill the rules during integrations.
Replication	Data can be replicated from or to this technology using Replicators.
Slowly Changing Dimension (SCD)	Slowly Changing Dimension (SCD) feature can be used optionnaly when integrating data in this technology.
Change Data Capture (CDC)	Change Data Capture (CDC), which allows to capture, follow and store all the changes during data integration, is supported.

Feature

Description

Reverse

Metadata can be reverse engineered.

DDL/DML Operations

DML/DDL operations can be performed on the database, such as: Insert, Update, Select, Delete, Create or Drop.

Integration Methods

Append
Incremental Update

Load Methods

Generic Load
Oracle SQL*Loader
External tables
Database Link (Oracle to Oracle)

Staging Methods

This technology can be used as a staging to make data transformation, mutualization, and more.

The following methods are supported:

Staging as Sub-Query
Staging as View
Staging as Table

Rejects

Reject rules can be defined to filter or detect data that does not fulfill the rules during integrations.

Replication

Data can be replicated from or to this technology using Replicators.

Slowly Changing Dimension (SCD)

Slowly Changing Dimension (SCD) feature can be used optionnaly when integrating data in this technology.

Change Data Capture (CDC)

Change Data Capture (CDC), which allows to capture, follow and store all the changes during data integration, is supported.

Sub-Metadata support

The Oracle component lets you create Sub-Metadata on Oracle Database schema and query folder Metadata nodes.

To learn more about Sub-Metadata, see Work with Sub-Metadata.

Additional Features

Feature	Description
Table analysis	Analyze work and target tables with ANALYZE TABLE or DBMS_STATS.GATHER_TABLE_STATS to optimize data loading during integrations.

Feature

Description

Table analysis

Analyze work and target tables with ANALYZE TABLE or DBMS_STATS.GATHER_TABLE_STATS to optimize data loading during integrations.

Change Data Capture may depend on your Oracle license. When capturing changes using anything other than the triggers, make sure the license includes rights to use the template features.

Limitations

Support for XML type columns requires additional libraries that do not come with Semarchy xDI. You must find and add the following JAR libraries to the Oracle module:

orai18n (orai18n-<version>.jar, based on your database version)
xdb6.jar
xmlparserv2.jar

For instructions on adding libraries to a module, see Review or edit modules.
