Environment properties

Environment ID

This is a 2-character code that serves as the environment's unique identifier.

This ID is also used to name the file related to the replication process. For more details, see Naming structure of key programs.
Information noteWarning: Do not use this ID for another environment.

Source code

This is a 3-character code that identifies the source.

Information noteWarning: Do not use this ID for another source.
This ID is very important in bidirectional replication to identify separately the replicating system (secondary machine) and the one that is replicated (primary machine), and to manage exclusion rules. For more details, see Configuring bidirectional replication.

Hold

Use this check box as follows:

  • select it to restrain the start (or hold) of all distributions created in the environment,
  • unselect it to allow the start (or release) of all distributions created in the environment.

Environment type

Environments are classified according to the type you assign, namely Production, Test, Training, Model and Deployment. The type is very important for global environment functions (DDCTL, DDJRN and more).

Access related to user

This parameter is used to secure an environment.

After selecting this option, the Users tab is enabled. In this tab, you can specify authorized users and their security level (see Securing the access to Talend Change Data Capture).

Description

Enter a description for the selected environment.

Time lapse between journal updates

This parameter is the idle time that occurs in a replication, when there are no more items to process in the journal.
  • If the value is included between 1 and 60 seconds, it corresponds to the number of seconds before a new analysis of the journal items is performed.
  • If the value is set to 0 second, it means a new item is taken into account as soon as it enters the journal.
Information noteNote: The time lapse directly impacts the time allowed for data to be available on the target database. The distribution may be delayed if the time lapse is long.

With AS/400 IBMi as a target, this parameter can be used to close the files automatically, when the source reaches the end of the journal.

Retry time lapse in case of communication error between source and target

This parameter specifies the number of minutes for connection attempts to the target engine, after communication errors have occurred. There is a 30-second gap between two attempts.

Its value ranges from 0 to 999.

Information noteNote: If the value is 0, when the first communication error occurs, the communication is stopped and no more attempts are made.
