Configuring TCP/IP stack affinity

About this task

When multiple TCP/IP stacks are in use on the system, you can specify the desired ZCC stack on the started task.

Create a new PDSE data set with LRECL=80 and RECFM=FB. For example:
```
<hlq>.EXMP.CONFIG
```
Create a new member in the data set, for example, <hlq>.EXMP.CONFIG(TCPDATA). In the new member, include the following line:
```
TCPIPJOBNAME TCPIPPRD
```
where TCPIPPRD is the name of the desired TCP/IP stack.
In the IPVCONFIG member , for example, <hlq>.EXMP.CONFIG(IPVCONFIG), add the following line to each product's SPAWN_PARMS_SECTION:
```
 SPAWN_DD=SYSTCPD=<hlq>.EXMP.CONFIG(TCPDATA)
```
Restart the ZCC started task for the changes to take effect.
