The logger component supports two types of log streams:
This table highlights the main differences between Coupling Facility based and DASD only log streams:
Characteristic |

---|---|---|
Interim storage |
Coupling Facility List Structure |
Data space |
Multi-system sharing |
Shared by multiple connectors executing on multiple systems simultaneously. |
Shared by multiple connectors executing on a single system simultaneously. |
Multi-system access |
Accessible to all systems in the sysplex. |
Accessible to all systems in the sysplex, but, only one system can connect to the log stream at any point in time. |
Note: Even though CA SYSVIEW should not need to create Coupling Facility based log streams, the Logger component is designed to support both log stream types.
