z/OS® V2R1 Communications
Server provides the following TCP/IP serviceability enhancements:
- An additional message for configuration errors encountered during
device or interface activation is being provided. This new message
provides information that easily identifies the reason for the activation
failure.
- The FTP client is enhanced with trace messages to assist with
the diagnosis of problems that occur when opening files. In addition
to the already existing EZA2564W messages documenting a failure, these
trace messages will provide additional information about the root
cause of the failure. These new messages can be accessed by activating
the FTP client's FSC debug option.
- The following OMPROUTE serviceability enhancements are provided:
- Historical time tables are added to OMPROUTE and the TCP/IP stack
to help IBM® Support diagnose
OMPROUTE unresponsiveness problems related to the sysplex monitoring
function.
- A new OMPROUTE message, EZZ8174I, provides additional information
in cases where communication between OMPROUTE and the TCP/IP stack
fails.
- A new OMPROUTE console command that displays the global configuration
options is provided.
- The OMPROUTE_OPTIONS environment variable is ignored. The hello_hi
functionality previously provided by the OMPROUTE_OPTIONS environment
variable is always enabled to optimize processing inbound and outbound
OSPF hello packets so that potential adjacency failures with neighbors
are minimized.
