Under normal circumstances or if the server is not providing
this information to Workload Manager (WLM), the value of this
field is 100, indicating that the server is 100% healthy. Any
value that is less than 100 indicates that the server is experiencing
problem conditions that might prevent new work requests from being
successfully processed.
The health of the server is directly determined by information
that the server application provides to WLM through programming
interfaces. In this way, the WLM perceived health of the application
depends directly on the amount of information that an application
provides to WLM, if any. WLM uses this information to potentially
reduce the weight recommendations for specific server applications
that are experiencing problems. This enables sysplex distributor
to direct fewer new TCP connections to these servers, selecting
instead servers that are not experiencing these problems.
WLM considers the following components when determining the
health of a server application:
- Rate of abnormal transaction completions reported by the server application
- General health of the application as reported by the server application
For more information regarding the conditions leading to abnormal
transaction completions for a given server application, see the
documentation provided by the server application.
