NOTE: for the activities, ORACLE Database 11g Express Edition is used. By default, it creates a database called XE when installing, which will be used for all of the examples below.

Connect to OracleSQL

This activity connects to a OracleSQL Host. The Output of this activity should be used as input for all Connection parameters used for activities placed under OracleSQL category.

Activity Parameters

The Connect to OracleSQL activity parameters can be provided by manual inserted values or via IN arguments or variables:

Parameters:

Data Source (text box editor type) (type: string): the database name to connect to. In the screenshot above the default XE database is used on the specified server.
Password (password editor type) (type: string): the password for the provided username.
Password Binding (text box editor type) (type: string): bind to a variable containing the encrypted password for the Oracle server. (This parameter is used only when the user wants to send an encrypted password from outside the workflow, for example Flowster Portal).
Port (text box editor type) (type: int32): the port number.
Server Name (text box editor type) (type: string): the name or IP of the Oracle Server to connect to. If Oracle is installed on the same server where the activity is executed, then the field can remain blank. This field is recommended to be used when accessing an Oracle database created on a different server.
