You effect global filtering by writing and loading an EMS consumer distributor filter.
You can configure and use filters by using the SYSPARMS command operands
described in this subsection. To learn more about writing and using EMS consumer
distributor filters, refer to the EMS Manual.
Specifying the EMS Filter Library
Use the EMSFLTLIB operand of the SYSPARMS command to specify the subvolume
that stores EMS filter files. Specify EMSFLTLIB as a valid volume and subvolume. For
example, to specify a filter library of $DATA1.EMSFLTRS, issue the following
command:
SYSPARMS EMSFLTLIB=$DATA1.EMSFLTRS
The default filter library is $isv-vol.ZNNMDATA.
Loading and Flushing an EMS Filter
You can load an EMS filter into or remove a filter from a distributor online. Use the
EMSDISTFLT operand of the SYSPARMS command to load or remove an EMS filter.
Specify EMSDISTFLT as either a file ID or FLUSH, to remove the current EMS
distributor filter. For example, to load an EMS filter named FLTRDFLT, issue the
following command:
SYSPARMS EMSDISTFLT=FLTRDFLT
The change takes effect immediately. The default value is FLUSH, which means no
filter. Without a filter, the consumer distributor allows all EMS messages to flow to
the EMSPROC procedure.
