EZD2014I

Explanation
 The real-time application-controlled TCP/IP trace
network management interface (NMI) has been disabled because of an
error. The rsncode value provides the reason for
the error. See Real-time application-controlled
TCP/IP trace NMI in z/OS Communications Server: IP Programmer's Guide
and Reference for more information about this NMI.
In
the message text:  rsncode
A code that explains the error.  Possible values are:1
Unable to obtain the TCP/IP address space private storage for
internal control blocks
2
Unable to obtain the 64-bit common storage for internal control
blocks
3
Internal error

System action
 TCP/IP processing continues, but applications
will not be able to use the real-time application-controlled TCP/IP
trace NMI.

Operator response
 Save the system log for problem determination
and contact the system programmer.

System programmer response
 When the NMI has been disabled, the
TCP/IP stack must be recycled to enable it. Use the rsncode value
to determine what action to take before recycling the TCP/IP stack:1
Increase the size of the TCP/IP address space to ensure that enough
private storage is available for use by the NMI. If you continue to
receive this message with a rsncode value of 1,
obtain a dump of the TCP/IP address space and examine the private
storage usage. Under IPCS, you can use the z/OS® Communications Server TCPIPCS
MAP command to examine information from the dump about storage
use by the TCP/IP stack. See TCPIPCS MAP in z/OS Communications Server: IP Diagnosis Guide for more information about this command.
2
The amount of 64-bit common storage is controlled by the HVCOMMON
parameter in member IEASYSxx of PARMLIB. For more information about
this parameter, see the z/OS MVS Initialization and Tuning Reference. You can use the MVS™ console
command D VIRTSTOR,HVCOMMON to display the summary
information about the current use of the HVCOMMON storage on the MVS systems. For more information
about this command, see the z/OS MVS System Commands. Review the value specified on the HVCOMMON
parameter to determine whether it should be increased. If you continue
to receive this message with a rsncode value of
2, obtain a system dump and examine the 64-bit common storage usage.
Under IPCS, you can use the RSMDATA HVCOMMON command
to display detailed information about the users of the storage and
the ranges in use. For more information about this command, see the z/OS MVS Diagnosis: Reference.

Obtain a dump of the TCP/IP address space and contact the IBM® support center.

Automation
 You can set up the automation for this message,
so you will know when the NMI has been disabled.
