Defining an SAP System as a Data
Source 
Use
Use the user management configuration tool to provide the details required to connect to an SAP System using the Remote Function Call (RFC) protocol.
When the user management service is initialized, an SAP connection pool is established to improve performance. This pool establishes a predefined number of SAP connections. To create the pool, a "service" user ID and password are required, as well as other logon and pool configuration parameters.
Prerequisites
The SAP System must be based on SAP Web Application Server 6.20 or higher.
Procedure
...
1. Start the user management configuration tool by choosing System Administration ® System Configuration ® UM Configuration.
2. Choose the SAP System tab.
3. Enter data in the fields as follows:
Field Name |
Field Data |
Client |
SAP System client, for example 100. |
User ID |
User ID in SAP System with which the connection to the SAP System is set up. We recommend using the user ID SAPJSF_<SID>. For details, see Requirements for Service User Used to Connect to SAP Systems. |
Password |
Password of the above user. |
System Language |
Any messages sent from the SAP System, for example error messages, are sent in this language. Defaults to SAP system user’s value. |
System ID* |
Three-character
code for SAP System, for example ABC. |
Group* |
Name of message server group, for example, PUBLIC. |
Message Server* |
Message server host address, for example, server01.mycompany.com. |
Application Server* |
Application server host address, for example, server02.mycompany.com. |
System Number* |
SAP System number, for example, 12. |
Maximum Size of Connection Pool |
Optional. Default value is 10. Maximum number of open connections in connection pool. The limit to the connections is limited by the memory size in the SAP system. Refer to the SAP Java connector documentation for details. |
Maximum Wait Time in Milliseconds |
Optional. Default value is 10,000. Maximum time that an incoming request waits for a connection before throwing an exception. If an exception gets thrown, this indicates that the number of connections allocated to the pool is not sufficient to handle the load. In this case the number should be increased. |
* Enter one of the following combinations of entries for the SAP System:
If you have a loadbalanced SAP System and the file sapmsg.ini is available on every portal server:
System ID + (optional) Group
If you have a loadbalanced SAP System and sapmsg.ini is not available on every portal server:
System ID + Message Server + Group
If the SAP System is not loadbalanced:
Application Server + System Number
4. Choose Save to save the entire configuration (that is, data from all the tabs). Otherwise choose Reset to undo all data you have entered on this tab.
After changing settings using the configuration tool, you must restart the Java application server for the changes to take effect.
