Member field - ABNORM

This field is displayed if the GROUP FLAGS field indicates that server-specific (SERVERWLM) WLM recommendations are being used. The ABNORM value is a nonzero value if the server application is experiencing conditions in which transactions are completing abnormally, and represents a rate of abnormal transaction completions per 1000 total transaction completions. It is applicable only for target applications that act as Subsystem Work Managers, reporting transaction status using Workload Management Services, such as IWMRPT. For example, the value of 200 in this example (see Line 28c in Figure 1) indicates that 20% of all transactions processed by the server application are completing abnormally. Under normal conditions or if the server is not providing this information to WLM, this value is 0.

A nonzero value indicates that the server application has reported abnormal transaction completions to WLM and that WLM has reduced the server-specific recommendation for this server instance. The higher the value of this field, the greater the reduction in the recommendation provided by WLM. For more information regarding the conditions leading to abnormal transaction completions for a given server application, see the documentation provided by the server application.

Restriction: Although WLM uses the abnormal transaction completion rate provided by the application to reduce the server-specific recommendation, this information is available for display on an Advisor only if the Load Balancing Agents and the Advisor are running on a z/OS® V1R8 system. A z/OS V1R7 Load Balancing Agent does not provide this information to the Load Balancing Advisor. In this situation, a z/OS V1R8 Advisor shows a normal abnormal transaction completion rate of 0, even if WLM is reducing the server-specific recommendation because of a nonzero abnormal transaction completion rate reported from the application.
