TCP/IP Subagent
underlying-process
is the name of the underlying process whose failure caused the interface between
the TCP/IP Subagent and the TCP/IP process to go out of service. The name of
one of the following processes is inserted in the message text following "underlying
object":
The name of the TCP/IP process specified for the subagent's private
ztsaTcpIpProcess MIB object
The name of the SCP process specified for the subagent's private
ztsaScpProcess MIB object
The name of the SNMP agent process specified for the subagent's private
ztsaAgentName MIB object
This information is displayed only if the value of the ZEMS-TKN-CHANGE-
REASON is ZEMS-VAL-UNDERLYING-FAILED.
code-location/internal-context-text
indicates where in the subsystem or application code the fault occurred.
ZEMS-VAL-NULL
indicates the type of subsystem-defined event. Because the TCP/IP Subagent
process has not defined this as a private event, the DDL AS clause "undefined"
always appears in the message text following "user content."
Cause. The TCP/IP Subagent process lost its connection to the configured TCP/IP
process (ztsaTcpIpProcess), the SCP SPI interface process (ztsaScpProcess), or the
SNMP agent process (ztsaAgentName).
If the underlying object is the SNMP agent process (ztsaAgentName), the subagent
has lost its connection to the agent process and has temporarily disconnected the
TCP/IP interface to conserve resources.
Effect. Values for the MIB-II objects supported by the TCP/IP Subagent are not
computed. SNMP requests for these MIB-II objects receive an SNMP-ERR-GEN-
ERROR response. Private MIB objects supported by the TCP/IP Subagent can still be
accessed.
Recovery. If the underlying object is the TCP/IP process or the SCP process, use
SCF to check the operating state of the TCP/IP or SCP process. The subagent
attempts to reacquire the TCP/IP connection according to the value of its
ztsaKeepAliveTimer object.
If no error conditions are found in the TCP/IP and SCP processes, or if the subagent
fails to reacquire the SCP interface, stop and restart the subagent.
