5 Performance Data / Operation
Limitation by the CPU
In productive operation, the number of simultaneous SEND/RECEIVE calls
depends on the CPU resources being used. Note the information on the available
CPU resources in Section 2.2.
The following CPU resources are required:
S Per SEND job short (FC5) or long (FC50):
S Per RECEIVE job short (FC6):
S Per RECEIVE job long (FC60):
S Per SPEED SEND/RECV job (FC53, FC63):
Limitation by the CP
A maximum of 64 SEND/RECEIVE connections can be operated by the CP.
At an assignment of 1 CP per CPU, the maximum number of SEND/RECEIVE
calls that can be used at one time is limited as follows:
S SEND calls short (FC5) or long (FC50):
S RECEIVE calls short (FC6):
S RECEIVE calls long (FC60):
)
*
The values apply to the CPU 416 and CPU 417.
)
*
The values apply to the CPU 412 and CPU 414.
)
***
The number of FC60s that can be used at the same time depends on the
number of SEND calls active at the same time (see Tables 5-4 and 5-5).
