PI77706: TPV STATISTIC COUNTER IS AGGREGATED INCORRECTLY.

APAR status

Closed as program error.

Error description

TPV displays a statistic of parent node as well as its child
node. If we select "JDBC Provider", TPV should aggregate its
child DataSources.
But statistics like PercentUsed is aggregated wrongly. Here is
an example.
TPV JDBC connection has following modules and sub modules.
- JDBC Connection Pools
   + JDBC Provider (Derby, DB2 etc)
     + Data Source 1  (Connection pool maxium connection = 2)
     + Data Source 2  (Connection pool maxium connection = 3)
Here is the result when we use 1 connection of each data
sources.
    - JDBC Connection Pools - PercentUsed : 83 %
      + JDBC Provider       - PercentUsed : 83 %
        + Data Source 1     - PercentUsed : 50 %
        + Data Source 2     - PercentUsed : 33 %
PercentUsed of parent node shouldn't be just summed. It should
be
aggregated to reflect actual usage of child datasources.

Local fix

****************************************************************
PMI counters for percentage data are aggregated by summing child
stats. This will cause the value to be go over 100%. The correct
aggregation technique should be the sum of child stats dividing
the
number of child stats.
