z/VM: System Messages and Codes Š CP - z/VM - IBM

If an unidentified program interrupt code occurs, you
may have to contact your IBM support personnel.
PRG128
Explanation: A PER (program event recording) event
occurred while CP was in control.
User Response: Study the dump to determine why
the particular program exception occurred. The program
old PSW points to where the program exception
occurred.
If an unidentified program interrupt code occurs, you
may have to contact your IBM support personnel.
PRG255
Explanation: Abend PRG255 occurs during the trace
page switch routine, if the processing unit address in
the new trace table page does not match the address of
the processing unit currently running.
User Response: Study the dump to determine what
happened to the chain of trace table pages belonging to
this processing unit.
PTA001
Explanation: The available list replenishment function
was attempting to take a frame from a user-owned
frame list, but the frames on the list were chained
improperly.
User Response: Inspect the process of chaining and
unchaining frames from the user-owned frame list.
Examine the dump and determine which VMDBK or
SNTBK owns this user-owned frame list. VMDFR1ST
should point to the first frame on the list, and
VMDFRLST should point to the last frame on the list.
The frame being unchained at the time of the ABEND
may not have been chained properly when it was put on
the user-owned frame list. R14 points to the address in
HCPPTA where CP detected the abend.
PTA002
Explanation: An attempt was made to reclaim a real
storage frame currently containing a pageable page, but
the required serialization (the owning virtual
configuration’s base VMDBK VMDPTIL Page Table
Invalidation Lock) is not held shared or exclusive.
User Response: Refer to z/VM: Diagnosis Guide for
information on gathering the documentation you need to
assist IBM in diagnosing the problem, then contact your
IBM support personnel.
PTC001
Explanation: An error was detected while trying to
add a frame to the User Frame Owned List.
User Response: Contact your IBM support personnel.
PTE002
Explanation: CP cannot return the frame specified by
R2 to the list of available frames, due to one of the
following conditions:
v The frame is locked.
v The frame is already chained on the available list.
v The frame is chained on a user-owned frame list.
User Response: Examine the dump to determine why
the abend was issued. Once you determine the reason,
trace back through system execution to determine which
module caused the error. Then examine the code to see
what caused the error to occur.
PTE006
Explanation: CP cannot return the frame specified by
R2 to the available list because, in its FRMTE, the
FRMPTE was pointing to a PAGTE that is still valid and
still pointed to this frame.
User Response: Examine the dump to determine
which module attempted to return the frame. Examine
the code to determine why validation of the PAGTE did
not take place.
PTE008
Explanation: The frame usage codes specified in R2
are not in a valid combination. CP cannot determine the
required usage.
User Response: Examine the dump to determine
which module was requesting a frame. Examine the
code in that module to determine why there was no
specification of a valid code.
PTE010
PRG128 PTE010
Explanation: While adding a frame to the available list
or taking a frame from the available list, CP determined
that the frames on the list were chained improperly. Or,
the count of available frames became negative.
User Response: Inspect the process of chaining and
unchaining frames on the available list. Examine the
dump for previous manipulations of the available list to
see when and where the error occurred. Then
determine the reason for the error by examining the
code for the module that caused the error.
