Oracle

You can create Oracle environments and can also enable RAC/Service to:

• Use Oracle cluster database
• Capture Oracle Service name in DSN field

Before creating an Oracle environment, you should take a note of the following:

• Prerequisites
• JDBC driver details
• TLS connection details
• JDBC connection parameters

Prerequisites

Prerequisite steps for establishing successful connection:

• Creation of dedicated service account for erwin with Metadata read-only privileges in Oracle database
• Firewall connection open between Oracle and erwin DI application server
• Oracle Database port opened to accept connections from erwin DI application server

JDBC Driver Details

Oracle JDBC driver is out of box packaged with erwin DI application. Hence, no JDBC driver configuration is required from end user standpoint.

TLS Connection Details

• Oracle JDBC 8 driver provides native TLS 1.2 support and upgrading the driver to JDBC 8 will provide the necessary resolution.
• Once the product is upgraded to the oracle JDBC 8 driver, TLS connectivity can be ensured by setting a few system parameters and also adding TLS parameters to the JDBC URL string to support connectivity using TLS 1.2

URL Format: jdbc:oracle:thin:@<Ip Address>:<Port>/< service name>+TLS params

JDBC Connection Parameters

The Connection Properties tab displays the connection parameters to establish connection for SQL Server (SQL authentication) connection.

Once the connection parameters are entered, use these options to go to the next tab, test the connections, save and continue, or save and exit.

Enter appropriate values in the fields (connection parameters). The fields marked with a red asterisk are mandatory.

Field Name	Description
Driver Name	Specifies the JDBC driver name for connecting to the database. For example, oracle.jdbc.driver.OracleDriver
IP Address/Host Name	Enter the IP address or server host name. For example, 10.32.445.21
DBMS Name/DSN	Name of the Oracle Service – SID or TNS Service Name. For example, ErwinDIS931.
Port	Specifies the port to connect with the database. 1521 is the default port for the Oracle database. User can change it, if required.
User Name	Enter the Oracle (Service account) user name. For example, erwinuser.
URL	It is autopopulated based on the other parameters. For example, jdbc:oracle:thin:@ <Ip Address>:<Port>/< service name>
Password	Enter the Oracle (Service account) password. For example, goerwin@1.
Save Password	Specifies whether the password is saved
DBMS Instant Schema	Specifies the name of the database schema. For example, DBO. Use this option to select multiple or narrow down to single schema.
Connection Pool Type	Specifies the connection pool type being used to connect via JDBC. For example, HIKARICP and BONECP. Select the appropriate connection pool type.
Number of Partitions	Specifies the number of partitions of the database. It is autopopulated with default number of partitions. You can edit and provide the number of partitions as required. For example, 2.
Minimum Connections Per Partitions	Specifies the minimum connections per partitions of the database. It is autopopulated with default minimum connections per partitions. You can edit and provide the minimum connections per partitions as required. For example, 3.
Maximum Connections Per Partitions	Specifies the maximum connections per partitions of the database. It is autopopulated with default maximum connections per partitions. You can edit and provide the maximum connections per partitions as required. For example, 5.

To use database options, click (Options).

The Database Options page appears. It displays the available database options.

To use the database options, select keys and double-click the cells under the Value column to set the values of the keys. Use to save the database options.
