Establishing an HTTP Connection from the Application System to XML DAS
To enable communication between the application system (AS ABAP), whose information you manage with SAP NetWeaver ILM, and XML DAS you need to establish an HTTP connection.
You need to activate this system-wide HTTP connection in each client of the application system from which you want to archive data using XML DAS. In this way, in addition to storing the archive files, you can also store references to the related documents that were stored with ArchiveLink.
You can also adjust the parameter values of the HTTP provider as required.
1. Creating the HTTP Connection to XML DAS
Trigger transaction SM59 in the application system (AS ABAP).
Enter the following general data:
RFC Destination: Name of the HTTP connection
Connection Type: G (HTTP connection to external server)
Define the HTTP connection as follows:
Target Host IP address for the AS Java on which XML DAS runs
Service No. HTTP Port of the Target Host
Path Prefix /DataArchivingService/DAS
Logon and Security
Logon Using User Basic Authentication
Logon User: Communication user that you have created in user administration.
HTTP Version: HTTP 1.1
Accept Cookies: Yes (All)
To avoid timeouts when there is a high volume of data, adjust the corresponding parameters for the HTTP connection as required.End of the note.
2. Activate HTTP connection to XML DAS for each client
Call transaction SARA in each client of the application system.
Under Cross-Archiving-Object Customizing, choose Technical Settings.
Under HTTP Connection to XML DAS for WebDAV Store, enter the name of the HTTP connection.
Optional: Adjust parameter values of the HTTP provider
Call up Visual Administrator for the AS Java on which XML DAS runs.
To change the maximum value for the size of archive files (131,072 KB = 128 MB), proceed as follows:
Select the parameter MaxRequestContentLength and adjust the value in the lower part of your screen.
To optimize the parameter values that influence data transfer when there is a high volume of data, proceed as follows:
Select the following parameters and adjust the values in the lower part of your screen.
For more information about the parameters, go to the SAP Help Portal in the Internet under the search term Long Data Transfer Mechanism.
