BPXO057I

Explanation
 text is either: NO RESOURCE CONTENTION EXISTS
Or a
report, as follows:
 UNIX SERIALIZATION REPORT
RESOURCE     #n:     
 NAME= object    DATA: SHMID=nnnnnnnn 
  OFFS/ADDR=nnnnnnnnnnnnnnnn
 JOBNAME ASID TCB        PID    USER DATA  
     EXC/SHR  OWN/WAIT 
⋮
RESOURCE    #n:         

 NAME= object    DATA: SHMID=nnnnnnnn 
  OFFS/ADDR=nnnnnnnnnnnnnnnn
JOBNAME ASID TCB        PID    USER DATA   
    EXC/SHR  OWN/WAIT 
⋮
RESOURCE      #nnnn  IS LOCKED
BY   
NAME= object    DATA: SHMID=nnnnnnnn 
  OFFS/ADDR=nnnnnnnnnnnnnnnn

 In response to a D OMVS,SER command, the system returns
message NO RESOURCE CONTENTION when no  resource contention
exists for the ownership of shared-memory mutexes (mutual exclusion
locks) or condition variables.
 If there is resource contention
for the ownership of shared-memory mutexes (mutual exclusion locks)
or condition variables the response to a D OMVS,SER command includes
the detailed form of this message.
 In the message text:  hh.mm.ss
The time in hours (00–23), minutes (00–59), and seconds
(00–59) for the DISPLAY OMVS command.
procname
The name of the z/OS UNIX cataloged
procedure.
status
One of the following:  ACTIVE
z/OS UNIX is
currently active.
NOT STARTED
z/OS UNIX was
not started.
INITIALIZING
z/OS UNIX is
initializing.
TERMINATING
z/OS UNIX is
terminating.
TERMINATED
z/OS UNIX has
terminated.
ETC/INIT WAIT
z/OS UNIX is
waiting for the /etc/init or /usr/sbin/init program
to complete initialization.
FORK SHUTDOWN
 FORK Service has been shutdown.
SHUTTING DOWN
z/OS UNIX is
shutting down.
SHUTDOWN BLOCKED
z/OS UNIX shutdown
processing is blocked by one or more jobs, and it waits for all of
the blockers to unblock or terminate.
SHUTDOWN
z/OS UNIX is
shut down.
RESTARTING
z/OS UNIX is
restarting after a shut down.

parmmemberlist
The parmlib member name list specified on the SET OMVS command
or on the initialization of OMVS. 
RESOURCE #n
An indication to separately identify specific shared objects (mutex
or condition variable) within the message table.
NAME=object
The type of object (MUTEX or condition variable (CONDVAR) for
which the lock is held
SHMID=nnnnnnnn
The shared memory ID of the task control block holding or waiting
on the held object. 
OFFS / ADDR=nnnnnnnnnnnnnnnn
 For objects in an above-the-bar memory segment: the address
the object
 For segments below the bar: the offset within the
shared memory segment because an address space below the bar can map
it at a different virtual address.

JOBNAME
The job name of the job holding or waiting on the held object.
ASID
The address space ID (ASID) of the task control block holding
or waiting on the held object. 
TCB
The hexadecimal address of the task control block (TCB) holding
or waiting on the held object. 
USER DATA
The 16–digit address of the user data.
EXC/SHR
The job (jobname) is the exclusive owner (EXE) of the shared object
(mutex or condition variable) or is sharing (SHR) it with another
task.
OWN/WAIT
The job (jobname) is the current owner (OWN) of the shared object
(mutex or condition variable) or the task waiting (WAIT) to gain access
to it.

System action
 Processing continues.

Operator response
 None.

System programmer response
 None. Unless you have determined
a specific job has held a shared object for an excessive length of
time (and possibly in a stalled or looping condition) to the detriment
of overall job processing. If such is the case, consider cancelling
the offending job.
