Use

Communication can be established between the systems in a system group in various operating statuses depending on the situation.

Integration

See also Synchronization Mechanisms .

Features

The systems in the system group can have the following operating statuses:

System Type

You use the System Type property to specify whether a system is usually in Offline or Online connection mode.

Planned Offline

The system is usually not connected to a partner system over a longer period of time and is therefore usually in the Offline connection mode.

Planned Online

The system is usually connected to a partner system over a longer period of time and is therefore usually in the Online connection mode.

You define the system type in Customizing for Defense Forces & Public Security → Distributed System Landscape → Systems and Connection Parameters.

This property is primarily for information purposes and controls only the output of error messages: An interrupted connection is always handled as an error for systems of system type Planned Online , but only under certain circumstances for systems of system type Planned Offline .

If you change the system type of a system, you must delete the CCMS node that belongs to this system and recreate it using the report /ISDFPS/ALE_CREATE_CCMS_NODE.

Connection Mode

The connection mode determines whether a system can currently establish a connection to its partner system.

Offline

The connection has been interrupted. The synchronization report is stopped. The system has the Offline connection status.

You use the Set System to OFFLINE Mode application (transaction /ISDFPS/SET_OFFLINE) to manually set a system to Offline mode.

You use the connection parameters to specify the number of attempts to establish a connection after which the system automatically sets the mode to Offline .

Online

The system can establish a connection to its partner system. The system can have Online or Offline connection status.

You use the Set System to ONLINE Mode application (transaction /ISDFPS/SET_ONLINE) to manually set a system to Online mode.

Connection Status

The connection status determines whether a system is actually currently physically connected to its partner system.

Offline

If the system status is Offline , it is not connected to its partner system.

Online

If the system status is Online , it is connected to its partner system.

Communication Status

The communication status specifies how data is currently being exchanged. See also Synchronization Mechanisms .

Wait/Offline

Systems with Offline connection status have the Wait (central system) or Offline (decentralized systems) communication status.

Sync

Systems with Online connection status have the Sync communication status while synchronization is running.

Comm

Systems with the Online connection status have the Comm communication status while synchronization is not running and current transaction data can be sent immediately.

An overview of the systems in the system group and their system type, connection mode, and communication status is available with ALE Status Monitoring and CCMS Monitoring . You can also check the current communication link using the Status of Connection to Partner System application (transaction /ISDFPS/SYSTEM_STATE).
