IP Stack Considerations

The SA z/OS ProcOps SNMP (TCP/IP) transport requires an IP stack to be active on the ProcOps FP system. The BCPii transport does not have this requirement. SA z/OS ProcOps supports multiple IP stacks on the FP system on a SE/HMC connection level. You can therefore predefine the IP stack to be used for a specific SE/HMC connection with the SA z/OS customization dialog. If you do not define an IP stack name, the system default stack is used.

Adjusting the Receive Buffer size of the ProcOps FP IP stack is an efficient way to prevent CI events from getting lost. See ProcOps SNMP Sessions for more details about lost events. SA z/OS ProcOps uses the Receive Buffer size value that is specified in the configuration file of the IP stack. With a larger Receive Buffer size, more CI event data can be queued to the ProcOps FP system IP stack before a Receive Buffer full condition occurs and a negative response must be returned to the SE/HMC.
