tInformixOutputBulkExec Standard properties

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

Property Type

Either Built-in or Repository .

No properties stored centrally

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

Execution platform

Select the operating system you are using.

Use an existing connection

Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined.

Host

Database server IP address.

Port

DB server listening port.

Database

Name of the database.

Schema

Name of the schema.

Username and Password

DB user authentication data.

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.

Instance

Name of the Informix instance to be used. This information can generally be found in the SQL hosts file.

Table

Name of the table to be written. Note that only one table can be written at a time and the table must already exist for the insert operation to be authorised.

Action on table

On the table defined, you can perform one of the following operations:

None: No operation is carried out.

Drop and create a table: The table is removed and created again.

Create a table: The table does not exist and gets created.

Create a table if not exists: The table is created if it does not exist.

Drop a table if exists and create: The table is removed if it already exists and created again.

Clear a table: The table content is deleted.

Schema and Edit schema

A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields.

Built-In: You create and store the schema locally for this component only.

Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs.

When the schema to be reused has default values that are integers or functions, ensure that these default values are not enclosed within quotation marks. If they are, you must remove the quotation marks manually.

For more information, see the related description of retrieving table schemas in Talend Studio User Guide.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

• View schema: choose this option to view the schema only.

• Change to built-in property: choose this option to change the schema to Built-in for local changes.

• Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion. If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window.

Informix Directory

Informix installation directory, e.g. " C:\Program Files\IBM\IBM Informix Dynamic Server\11.50\".

Data file

Name of the file to be generated and loaded.

Append

Select this check box to add rows to the end of the file.

Action on data

Select the operation you want to perform:

Bulk insert Bulk update The details asked will be different according to the action chosen.

Additional JDBC parameters

Specify additional connection properties for the DB connection you are creating. This option is not available if you have selected the Use an existing connection check box in the Basic settings.

Row separator

String (ex: "\n"on Unix) to distinguish rows.

Fields terminated by

Character, string or regular expression used to separate the fields

Set DBMONEY

Select this check box to define the decimal separator used in the corresponding field.

Set DBDATE

Select the date format you want to apply.

Rows Before Commit

Enter the number of rows to be processed before the commit.

Bad Rows Before Abort

Enter the number of rows in error at which point the Job should stop.

Create directory if not exists

This check box is selected by default. It creates a directory to hold the output table if required.

Custom the flush buffer size

Select this box in order to customize the memory size used to store the data temporarily. In the Row number field enter the number of rows at which point the memory should be freed.

Encoding

Select the encoding from the list or select Custom and define it manually. This field is compulsory for DB data handling.

tStatCatcher Statistics

Select this check box to collect the log data at a component level.

Output

Where the output should go.

Usage rule

This component is generally used when no particular transformation is required on the data to be inserted in the database.

Dynamic settings

Click the [+] button to add a row in the table and fill the Code field with a context variable to choose your database connection dynamically from multiple connections planned in your Job. This feature is useful when you need to access database tables having the same data structure but in different databases, especially when you are working in an environment where you cannot change your Job settings, for example, when your Job has to be deployed and executed independent of Talend Studio.

The Dynamic settings table is available only when the Use an existing connection check box is selected in the Basic settings view. Once a dynamic parameter is defined, the Component List box in the Basic settings view becomes unusable.

For examples on using dynamic parameters, see Reading data from databases through context-based dynamic connections and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic settings and context variables, see Talend Studio User Guide.

Limitation

The database server/client must be installed on the same machine where the Studio is installed or where the Job using tInformixOutputBulkExec is deployed, so that the component functions properly.
