tEXAConnection Standard properties - 7.3

Select a type of database from the list and click Apply.

Property Type

Either Built-In or Repository.

• Built-In: No property data stored centrally.

• Repository: Select the repository file in which the properties are stored. The database connection fields that follow are completed automatically using the data retrieved.

Host

Enter the host or host list of the EXASol database servers. EXASol can run in a cluster environment. The valid value can be a simple IP address (for example, 172.16.173.128), an IP range list (for example, 172.16.173.128..130 that represents three servers 172.16.173.128, 172.16.173.129, and 172.16.173.130), or a comma-separated host list (for example, server1,server2,server3) of the Exasol database cluster.

Port

Enter the listening port number of the Exasol database cluster.

Schema

Enter the name of the schema you want to use.

Username and Password

Enter the user authentication data to access the Exasol database.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

Use or register a shared DB Connection

Select this check box to share your database connection or fetch a database connection shared by a parent or child Job, and in the Shared DB Connection Name field displayed, enter the name for the shared database connection. This allows you to share one single database connection (except the database schema setting) among several database connection components from different Job levels that can be either parent or child.

This option is incompatible with the Use dynamic Job and Use an independent process to run subJob options of the tRunJob component. Using a shared connection together with a tRunJob component with either of these two options enabled will cause your Job to fail.

Auto Commit

Select this check box to commit any changes to the database automatically upon the transaction.

With this check box selected, you cannot use the corresponding commit component to commit changes to the database; likewise, when using the corresponding commit component, this check box has to be cleared. By default, the auto commit function is disabled and changes must be committed explicitly using the corresponding commit component.

Note that the auto commit function commits each SQL statement as a single transaction immediately after the statement is executed while the commit component does not commit only until all of the statements are executed. For this reason, if you need more room to manage your transactions in a Job, it is recommended to use the commit component.

Additional JDBC Parameters

Specify additional connection properties for the database connection you are creating. The properties are separated by semicolon and each property is a key-value pair, for example, encryption=1;clientname=Talend.

This field is not available if the Use an existing connection check box is selected.

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at the Job level as well as at each component level.

Global Variables

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

Usage rule

This component is more commonly used with other Exasol components, especially with the tEXACommit and tEXARollback components.
