HCP1025E A recursive trace call cannot be done.
Explanation: During TRACE command processing, a
recursive call has been attempted to a current trace set.
System Action: The trace call is ignored.
User Response: Modify the trace set to remove the
recursion.
HCP1026E The trace return cannot be done
because there is no matching trace
call.
Explanation: During TRACE command processing,
CP detected a TRACE RETURN that it could not match
to a TRACE CALL.
System Action: The trace event is ignored.
User Response: Modify the trace set to remove the
TRACE RETURN that is in error.
HCP1027I An active trace set has turned RUN off.
Explanation: You issued a TRACE command that
made a TRACE set active. The setting that allows your
virtual machine to continue running has been turned off.
System Action: System operation continues.
User Response: To turn RUN on again, you must
specify SET RUN ON when a TRACE set is not active.
HCP1028E Trace entry cannot complete due to
paging error.
Explanation: During TRACE processing, the system
detected a system or user paging error.
System Action: The trace event is ignored.
User Response: None.
HCP1029E CCW tracing cannot complete because
the maximum buffer size has been
exceeded.
Explanation: Trace information is collected in a
fixed-size virtual storage area. This message indicates
that the trace information for a single channel program
has exceeded the fixed size.
System Action: Further CCW tracing is terminated.
User Response: This situation arises when large
amounts of trace information are collected for very long
or very complex channel programs. The only way to
reduce the volume of trace information is to simplify the
channel program.
Operator Response: None.
HCP1030E CCW tracing cannot complete due to
{a system virtual storage paging
error|a VDISK storage error}
Explanation: The usual cause of a paging error is an
I/O error on a paging device.
System Virtual Storage Paging Error
Trace information is collected in system virtual
storage pages before being displayed or
printed. CP encountered a paging error that
prevented it from reading a system virtual
storage page.
VDISK Storage Error
Trace information is collected for some virtual
disk in storage supported CCWs by reading
data from the virtual disk in storage address
space. A storage error occurred that prevented
the reading of such information, and it is
probably a paging error.
System Action: Further CCW tracing is terminated.
User Response: None. If the error persists related to
storage for virtual disks in storage, contact your IBM
support personnel.
Operator Response: None.
HCP1031I SET RUN ON is not allowed when the
trace function is active.
Explanation: The command SET RUN ON cannot be
used when TRACE is active.
System Action: The command is ignored; system
operation continues.
User Response: To turn RUN on, you must specify
SET RUN ON when a TRACE set is not active.
HCP1032E A syntax error was encountered.
Explanation: The syntax of an expression in the
command line is invalid.
System Action: The command is not executed;
system operation continues.
User Response: Determine why the syntax is invalid
and reissue the command using a valid expression.
HCP1033I No SPECIFIC CP TRACE is in effect.
Explanation: You attempted to modify specific tracing
when there was no specific tracing in effect.
System Action: None.
User Response: Issue the QUERY CPTRACE
command to verify CPTRACE status.
Operator Response: None.
