The single predefined situation in this category monitors that OMEGAMON® is correctly configured to provide the required monitoring functions.
Use the OMEGAMON WLM Blocks Usage view on the Service Task Details workspace or the F agentname,OC STATUS,WLMBLOCKS diagnostic command to determine the peak usage that the system has experienced for either transaction or the accumulation records. Use the Configuration Tool to adjust the WLM Blocks parameter so the peak value of no more that 80% is ever experienced.
Accumulation records are used to hold summaries for service classes. There is an accumulation record for each combination of service calls, CICS region and transaction ID received, as well as one extra record for each CICS region. The volume depends upon the number of service classes defined, transactions that are categorized in those service classes and CICS regions.
There is a direct relationship between the WLM Blocks parameter and the maximum number of accumulation records. For example, if 500 blocks results in a consistent usage of 80%, changing the value to 1000 blocks results in a usage of 40%.
Formula
If the value of the attribute WLM_Accumulation_Data_Current_percent is greater than 70 or the value of the attribute WLM_Accumulation_Data_Peak_percent is greater than 80 then situation CICSplex_WLM_Blocks_Usage_High is true
