Client Fault Tolerance Target Host

The client fault tolerance target host parameter is only required for pre-XBP 2.0 client fault tolerance mode. If the secure CFT mode is being used, the client fault tolerance target host parameter is ignored.

As part of an external program command ID job step definition, SAP requires a target host on which to run the external program (echo). Universal Connector provides the client fault tolerance target host parameter to specify the target host for the command ID job step.

The Client Fault Tolerance Target Host is specified with the CFT_TARGET_HOST option.

Client Fault Tolerance Command Prefix

The client fault tolerance command prefix parameter is only required for pre-XBP 2.0 client fault tolerance mode. If the secure CFT mode is being used, the client fault tolerance command prefix parameter is ignored.

The external program command ID job step has the potential to be run on any operating system reachable by the SAP system. The operating system that the Command ID Job Step runs on is that which exists on the host system specified by the Client Fault Tolerance Target Host parameter. Different operating systems may require commands to be called in different ways. Therefore, the Client Fault Tolerance Command Prefix parameter allows the user to specify the prefix necessary to run the echo command on the host system specified by the Client Fault Tolerance Target Host parameter.

For example, to run the echo command on a Windows system, the following command line entry would be required for an SAP external job step: cmd /C echo. Therefore, the Client Fault Tolerance Command Prefix for this system would be: cmd /C.

The Client Fault Tolerance Command Prefix parameter is specified with the CFT_COMMAND_PREFIX option.

Secure Client Fault Tolerance Option

The mode of client fault tolerance to be used by Universal Connector is determined by the value of the SECURE_CFT option.

Valid values for this option are yes and no:

• yes will cause Universal Connector to use the Secure CFT mode.
• no will cause Universal Connector to use the original Pre-XBP 2.0 CFT mode.

The default value is yes.

Client Fault Tolerance ABAP Program

The client fault tolerance ABAP program parameter is only required for secure CFT mode. If the pre-XBP 2.0 CFT mode is being used, the client fault tolerance ABAP program parameter is ignored.

The client fault tolerance ABAP program parameter is used to specify the ABAP program to use for the command ID job step. Any ABAP program can be specified. The Universal Connector internal default ABAP program to use is BTCTEST. BTCTEST is a standard SAP ABAP program that should be available on all SAP systems. It does no real processing and can be considered a dummy program that does not interfere with job processing and places little overhead on the system.
