Oracle

Source and Destination Databases

Before you begin

Before you begin, gather this connection information:

• Name of the server that hosts the database you want to connect to and the Oracle service name and port

• User name and password

• Are you connecting to an SSL server? You must configure the Oracle client before you can use SSL

Connect and set up the workspace

Launch Syntho and select Connect to a database, or Create workspace. Then select Oracle from Type under The connection details. For a complete list of data connections, click Type under The connection details. Then do the following:

1. Enter the server name.

   • Note: To find the correct service name, open the tnsnames.ora file (in the ORACLE_HOME/network/admin directory by default) and search for the net_service_name section. Use the value listed for service_name.

2. Enter the database name to connect to the contained database.

3. Enter the port number.

4. Enter user name and password.

   Select the Require SSL check box when connecting to an SSL server.

5. Select Next. If Syntho can't make the connection, verify that your credentials are correct. If you still can't connect, your computer is having trouble locating the server. Contact your network administrator or database administrator.

Limitations

• There is a possibility for some Oracle DB system schemas to appear after creating workspace. This shouldn't happen if database permissions and schemas are set properly, but if it does happen then user should manually exclude schemas from synthetization. See below the list of schema that are excluded by default.

Supported data types

The following table provides a summary of the current support and limitations for various data types when using connectors with Oracle. It indicates what's supported per generator type, and if any additional processing is performed by Syntho to successfully generate and write the data.

Data Type	AI-powered Generation	Mockers	Mask	Calculated Columns
INTEGER	True	True	True	True
SMALLINT	True	True	True	True
NUMBER	True	True	True	True
FLOAT	True	True	True	True
BINARY_FLOAT	True	True	True	True
BINARY_DOUBLE	True	True	True	True
CHAR	True	True	True	True
VARCHAR2	True	True	True	True
NCHAR	True	True	True	True
NVARCHAR2	True	True	True	True
CLOB	False	False	False	False
DATE	True	True	True	False
TIMESTAMP	True	True	True	False
TIMESTAMP WITH TIME ZONE	True	True	True	False
TIMESTAMP WITH LOCAL TIME ZONE	True	True	True	False
INTERVAL YEAR TO MONTH	True	True	True	False
INTERVAL DAY TO SECOND	True	True	True	False
RAW	False	False	False	False
BLOB	False	False	False	False
NCLOB	False	False	False	False
ROWID	True*	True*	True*	True*
UROWID	True*	True*	True*	True*
XMLTYPE	True	True	True	True

*Some data types are not actively supported; however, certain generators such as AI synthesize, mask, mockers, or calculated columns may still show 'True' for these fields. This means the generators can be applied, even though the types are not actively supported. Duplication is fully supported for these data types.
