Enabling Near-Term History
Near-Term History captures and stores recent Db2 instrumentation data so that you can review thread performance after the threads have ended. Near-Term History is available through the Classic User Interface and OMEGAMON® enhanced 3270 user interface.
Procedure
Set parameter KD2_PFxx_HIS_START to Y or
C.
You can use variable %DB% for the Db2 subsystem ID or variable
%SY% for the system ID in the VSAM data set names. Variable
%DB% will be replaced by the Db2 subsystem ID for the
allocation of the data sets, and variable %SY% will be
replaced by the z/OS system ID that you configured.
