PIPE FANOUT
Syntax
FANOUT:
FANOUT
Command Description
The FANOUT stage copies the messages received on its primary input stream to all
connected output streams. Messages copied to the output streams are identical
except:
Streams
v Messages written to the primary output stream retain the IFRAUPRI primary
attribute of the original message. The copy attribute, defined by IFRAUCPY is
set to 0.
v Messages written to all other output streams have the IFRAUPRI primary
attribute setting set to 0 and the copy attribute, defined by IFRAUCPY set to 1.
For more information about IFRAUCPY and IFRAUPRI, see IBM Tivoli NetView for
z/OS Programming: Assembler.
Stream Type Number Supported
Input 1
Output 10
Termination Conditions
FANOUT ends when the input stream disconnects or all output streams
disconnect.
Operand Descriptions
This stage has no operands.
Usage Notes
Examples
PIPE FANOUT
v The messages are not written to the output streams in any predetermined order.
Streams waiting on input from FANOUT can be delayed.
v If more than 10 output streams are required from FANOUT, one of the output
streams can be used as an input tream to another FANOUT stage. Pass the
primary output stream from the second FANOUT stage to a HOLE stage
because the primary output from the second FANOUT stage does not have a
copy attribute.
Example: Driving Two Different Commands with the Same
Message
In the following example, messages contained in the safe named MYSAFE are
input to FANOUT. The primary output from FANOUT passes the message to
