Adabas Connector rules and guidelines

• •You can use Adabas connections for sources or targets.
• •Adabas Connector connects to a PowerExchange Listener on the PowerExchange source system by using the Listener Location property in the Adabas connection definition. On the connector system, you do not need to create a local copy of the dbmover.cfg configuration file that contains a NODE statement pointing to the PowerExchange Listener.
• •If you upgrade your system to a later PowerExchange version, you must stop the Secure Agent that connects to the older PowerExchange Listener before you try to connect to the upgraded PowerExchange Listener. After you edit the connection properties to specify the upgraded PowerExchange Listener, restart the Secure Agent before you try to establish the connection again. For more information, see Upgrading to a new version of PowerExchange.
• •The PowerExchange Listener can compress or encrypt the data that it sends to the PWX Reader component of Adabas Connector depending on how you set the Compression and Encryption properties for the connection.
• •If you include multiple Adabas source tables in a mapping, the PWX Reader automatically uses group source processing to read data for all of the tables in a single pass.
• • The maximum network buffer size that the PowerExchange Listener can use for sending data is 8 MB. If you have a mapping with an extremely large Adabas source table, this maximum buffer size might be exceeded. In this case, the mapping task fails with the following error:
PWXPC_10034 [date time] [ERROR] Dispatcher cannot fetch changed data from the PowerExchange Listener. Error code: [271]
• •If you change the source object in a mapping that has been used for processing, create a new mapping task for the mapping.
• •PowerExchange imports Long Alpha (LA) fields with a default length of 1,024 bytes. You can override this default length by editing the data map in the PowerExchange Navigator. For more information, see the PowerExchange Bulk Data Movement Guide.
• •PowerExchange can replicate data from Adabas spanned records up to their maximum size. The Adabas maximum size depends on the device type.
