RSHOSTPH checks whether system parameters of the host operating system have been changed since the last time it ran and logs any changes that have been made to database table PAHI.

As the parameter changes are stored only once a day, it is sufficient to schedule this program in table TCOLL with system =* to run once a day in each SAP instance.

If there are several instances of the same SAP system on one server, the data collector starts the program only once on this server.
