tPostgresPlusClose properties

Component family

Databases/Postgres

 

Function

tPostgresPlusClose closes the transaction committed in the connected DB.

Purpose

Close a transaction.

Basic settings

Component list

Select the tPostgresPlusConnection component in the list if more than one connection are planned for the current Job.

Advanced settings

tStat Catcher Statistics

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

 

Enable parallel execution

Select this check box to perform high-speed data processing, by treating multiple data flows simultaneously. Note that this feature depends on the database or the application ability to handle multiple inserts in parallel as well as the number of CPU affected. In the Number of parallel executions field, either:

  • Enter the number of parallel executions desired.

  • Press Ctrl + Space and select the appropriate context variable from the list. For further information, see Talend Studio User Guide.

Note that when parallel execution is enabled, it is not possible to use global variables to retrieve return values in a subjob.

Warning

  • The Action on table field is not available with the parallelization function. Therefore, you must use a tCreateTable component if you want to create a table.

  • When parallel execution is enabled, it is not possible to use global variables to retrieve return values in a subjob.

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.

Once a dynamic parameter is defined, the Component List box in the Basic settings view becomes unusable.

For examples on using dynamic parameters, see Scenario 3: Reading data from MySQL databases through context-based dynamic connections and Scenario: 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.

Usage

This component is to be used along with PostgresPlus components, especially with tPostgresPlusConnection and tPostgresPlusCommit.

Log4j

If you are using a subscription-based version of the Studio, the activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User Guide.

For more information on the log4j logging levels, see the Apache documentation at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html.
