Restart Control Attributes

Restart Control Attributes

Use PWXPC restart control attributes to identify restart information to use for a CDC session. The restart information determines the point from which PowerExchange starts reading change data for the session.
Specify restart control attributes in the following situations:
  • When you create CDC session.
  • When you add a source to an existing CDC session and need to specify restart information for that source.
  • When you want to override some restart information that is in the state table or file for a CDC session.
The following table describes the restart control attributes that you can enter on a PWX CDC application connection:
Connection Attribute
Description
Application Name
A unique application name for the CDC session. The application name is case sensitive and cannot exceed 20 characters.
Default is the first 20 characters of the workflow name. Because the default might not result in a unique name, Informatica recommends that you enter a unique name.
RestartToken File Folder
Directory name on the PowerCenter Integration Service machine that contains the restart token override file.
Default is $PMRootDir/Restart.
RestartToken File Name
The unique file name of the restart token file. This file is in the directory that is specified in the
RestartToken File Folder
attribute. PWXPC uses the contents of this file, if any, in conjunction with the state table or state file to determine the restart point for the CDC session.
Default is the
Application Name
value, or if you do not specify the application name, default is the workflow name.
The values for the
Application Name
and
RestartToken File Name
attributes must be unique for each CDC session. If either one of these values is not unique, unpredictable results might occur, including session failure and potential data loss.
