A name for the IMS CDC connection. This name must be unique within the organization. Connection names can contain alphanumeric characters, spaces, and the following special characters: _ . + -
Spaces at the beginning or end of the name are trimmed and are not saved as part of the name.
Maximum length is 100 characters. Connection names are not case sensitive.
Description of the IMS CDC connection. Maximum length is 4000 characters.
Type of connection. For IMS CDC, the type must be
Name of the runtime environment that contains the Secure Agent that you want to use to run mapping tasks.
Host name or IP address of the system where both the PowerExchange Listener that processes PWX CDC Reader requests for IMS change data and the PowerExchange Logger for Linux, UNIX, and Windows run. Also include the Listener port number. Enter the value in the following format, where
host_namecan be a host name or IP address:
A user name that can be used to access the PowerExchange Listener when PowerExchange Listener security is enabled. For more information, see the SECURITY statement in the
PowerExchange Reference Manual.
Password that is associated with the user name that is specified in the
The IMS instance that is specified in the
Database Instancefield of the registration group that contains the capture registrations for the IMS source. This value is used to filter the extraction-map metadata that the PWX CDC Metadata Adapter imports when using this connection.
CAPI Connection Name
Name of a CAPX CAPI_CONNECTION statement that is defined in the PowerExchange dbmover configuration file. This statement includes parameters that the PWX CDC Reader uses to extract change data from PowerExchange Logger for Linux, UNIX, and Windows log files. The PWX CDC Reader requires this property value and ignores any default CAPI_CONNECTION statement that is defined in the dbmover configuration file.
Connection Retry Period
Number of seconds that the PWX CDC Reader tries to reconnect to the PowerExchange Listener after the initial connection attempt fails. If a connection cannot be established within the retry period, the mapping task fails. The default is 0, which disables connection retries.
Controls whether the PowerExchange Listener compresses change data before sending the data over the network to the PWX CDC Reader. Select this property to compress the data. By default, this property is not selected.
Controls whether the PowerExchange Listener encrypts change data before sending it over the network to the PWX CDC Reader. Also specifies the type of encryption to use. Select one of the following options:
The default is
Amount of data, in rows or kilobytes, that the source system passes to the PowerExchange Listener before pausing to wait for another PWX CDC Reader request for more data. Decrease this value to improve session performance. Use 0 for maximum performance.
The default and minimum value is 0.
Type of units to use with the
Host name or IP address of the system where the extraction maps reside. Also include the port number.
This value is required when the PowerExchange Listener runs on a PowerExchange Logger for Linux, UNIX, and Windows machine that is remote from the extraction maps. The Listener requires access to the extraction maps to process change data extraction requests.
Enter the value in the following format, where
host_namecan be a host name or IP address:
Map Locationvalue takes precedence over the
Listener Locationvalue for testing connections and importing extraction-map metadata.
Map Location User
A user name that can access the PowerExchange Listener at the location that is specified in the
Map Location Password
Password associated with the user name that is specified in
Map Location Userproperty.
If you created an event table to stop change data extraction based on user-defined events, enter the name of the PowerExchange extraction map for the event table. The event table must be an IMS table on the CDC source system.
Replace Low Values with Spaces
Controls whether to replace embedded nulls in character data with spaces. Select this property to replace embedded nulls. By default, this property is selected.
Custom properties that you can specify to override PowerExchange default settings. You can enter multiple properties by using a semicolon (;) as the separator. Normally, you set custom properties only at the direction of Informatica Global Customer Support.
These properties are equivalent to the
PWX Overrideoptions for the PowerExchange Client for PowerCenter (PWXPC) IMS CDC connections in PowerCenter.
