adjustment and policy adjustment processing when the service class has been
assigned to a resource group and a resource group maximum has been defined.
The Type 99 SMF record is also planned to be extended to show when the number
of initiators to be started was limited for this reason. These changes are intended
to improve WLM batch management.
• Changes to the dispatching of discretionary work are planned. The system
will be designed to run discretionary work for a longer period of time before
dispatching other discretionary work, while still interrupting it after short periods
for nondiscretionary work. This change is intended to help improve the throughput
for systems with a high percentage of discretionary workloads.
• Capacity Provisioning is planned to use the delay data for transaction service
classes provided by RMF to help determine whether a provisioning action is
required for servers on which CICS and IMS are running. Monitoring delay
data for CICS and IMS transaction classes is intended to help improve capacity
provisioning decisions for servers with LPARs running CICS and IMS.
• The Capacity Provisioning Manager will be designed to allow you to specify that it
is to use rolling performance intervals to determine whether a provisioning action
should be taken rather than fixed intervals. This is intended to help improve the
responsiveness of capacity provisioning.
• In z/OS V1.12, z/OS Communications Server is planned to use new TCP/IP
callable NMI requests to provide TCP/IP stack network interface information and
network interface and global statistics. Network management applications can use
the requested output to monitor interface status and TCP/IP stack activity. z/OS
V1.12 Communications Server is planned to provide the following new requests:
– GetGlobalStats - Provides TCP/IP stack global counters for IP, ICMP, TCP, and
UDP processing
– GetIfs - Provides TCP/IP network interface attributes and IP addresses
– GetIfStats - Provides TCP/IP network interface counters
– GetIfStatsExtended - Provides data link control (DLC) network interface
counters
• New PDSE functions are planned. A new utility will be designed to verify that
the structure of a PDSE is valid, and programming services will be designed to
perform similar checking to help programs verify the state of a PDSE before and
after critical operations. These new functions are intended to help you detect
errors in PDSE structures that might otherwise go undetected.
• z/OS Communications Server plans to provide enhancements to improve the
management of the CSSMTP application by adding the following new SMF 119
record subtypes:
– 048 - CSSMTP Configuration data records
– 049 - CSSMTP Target server connection records
– 050 - CSSMTP Mail records
– 051 - CSSMTP Spool records
– 052 - CSSMTP Statistics records
It is intended that applications that want to process the new SMF 119 subtypes
can obtain them from a traditional MVS SMF exit routine or in real time from the
z/OS Communications Server Network Management Interface (NMI) for SMF,
SYSTCPSM.
CSSMTP issues the SIOCSAPPLDATA ioctl to add application data (appldata) to
the TCP connections used to connect to target mail servers. You can see the
application data (appldata) displayed in the Netstat All/-A, AllConn/-a, and Conn/-
c reports.
• z/OS Communications Server plans to introduce sysplex event notification through
new SMF 119 event records (subtypes 32 - 37) that describe the following events:
– DVIPA status change (subtype 32)
– DVIPA removed (subtype 33)
– DVIPA target added (subtype 34)
