The AUTO option is only available with the modify format start command.
This is true for both PDT and PSA.
Effectively, for the AUTO option to work there must be no manual
intervention i.e. when XMANAGER is started, that should initiate
the collection via the XMANINIT parms. While Xmanager remains up, any
stop of DB2 subsytems should stop the appropriate collection(s). When the
same DB2 subsystem is restarted, collection should automatically begin
If there has been a manual stop/start of collections in this process, then
the AUTO process will stop tracking until XMANAGER is recycled and the whole
process starts again.
