Using RMF reports to analyze message buffer space z/OS MVS Setting Up a Sysplex SA23-1399-00 |

To determine whether the signaling service was unable to satisfy
a message request, the Figure 1 provides the following
columns:
In the XCF Activity Report - Path Statistics shown in Figure 3, the following columns under the heading “INBOUND
TO sysname” are useful:
When requests for message buffers are rejected, determine whether the maximum amount of space that XCF is allowed to use for message buffers was too small to support the load (and therefore degrades system performance), or whether there was some unusual/failure condition that caused the limits on buffer space to be reached (in which case the limits performed their intended function because they prevented large amounts of storage from being obtained and further impacting the system). |
