Parameters
The parameters are explained as follows:
- name
- An optional symbol, starting in column 1, that is the name on
the IWM4MSTO macro invocation. The name must conform to the rules
for an ordinary assembler language symbol.
- ,AFTER_STRT=NO
- ,AFTER_STRT=YES
- When EWLM_RCVD_CORR=ewlm_rcvd_corr is specified, an
optional parameter, which indicates the moment the correlator has
been received. The default is AFTER_STRT=NO.
- ,AFTER_STRT=NO
-
indicates that the correlator has been received before this
work unit has been started by IWM4MSTR.
- ,AFTER_STRT=YES
-
indicates that the correlator has arrived within the scope
of this work unit that means after issuing IWM4MSTR.
- ,END_FLOW=NO
- ,END_FLOW=YES
- An optional parameter, which indicates the completion of a message
flow. The default is END_FLOW=NO.
- ,END_FLOW=NO
-
indicates that a message flow has not completed.
- ,END_FLOW=YES
-
indicates that a message flow has completed. Specify END_FLOW=YES,
if you know that the running work unit is the last one in a work unit
flow. This indication can not be cleared, if it has been set.
- ,EWLM=NO
- An optional parameter, which indicates if this work manager
intents to participate in cross platform Enterprise Workload Management
(eWLM). The default is EWLM=NO.
- ,EWLM=NO
- The work manager interacts only with WLM and no interaction
with eWLM takes place.
- ,EWLM_RCVD_CORR=ewlm_rcvd_corr
- ,EWLM_RCVD_CORR=NO_EWLM_RCVD_CORR
- An optional input parameter, which contains a cross platform
Enterprise Workload Management (EWLM) correlator received from another
application. Workflows often have multiple parent work units that
must complete before a new work unit can be initiated. You can pass
only 1 parent correlator to the IWM4MSTR macro and one additional
parent correlator to the IWM4MSTO macro. You have to issue the IWM4MUPD
macro, if more than two parent correlators should be assigned to a
work unit.
This correlator is ignored, if it is an unknown
EWLM correlator. The default is NO_EWLM_RCVD_CORR. indicates that
parameter EWLM_RCVD_CORR has not been specified.
To
code: Specify the RS-type address, or address in register
(2)-(12), of a character field.
- ,MESSAGES_SENT=messages_sent
- ,MESSAGES_SENT=NO_MESSAGES_SENT
- An optional input parameter, which contains the number of messages
sent to other applications. This value is added to the total messages_sent
value of the work unit. The total messages_sent value should not exceed
32767. The default is NO_MESSAGES_SENT. indicates that parameter MESSAGES_SEND
has not been specified.
To code: Specify
the RS-type address, or address in register (2)-(12), of a fullword
field, or specify a literal decimal value.
- ,MF=S
- ,MF=(L,list addr)
- ,MF=(L,list addr,attr)
- ,MF=(L,list addr,0D)
- ,MF=(E,list addr)
- ,MF=(E,list addr,COMPLETE)
- An optional input parameter that specifies the macro form.
Use
MF=S to specify the standard form of the macro, which builds an inline
parameter list and generates the macro invocation to transfer control
to the service. MF=S is the default.
Use MF=L to specify the
list form of the macro. Use the list form together with the execute
form of the macro for applications that require reentrant code. The
list form defines an area of storage that the execute form uses to
store the parameters. Only the PLISTVER parameter may be coded with
the list form of the macro.
Use MF=E to specify the execute
form of the macro. Use the execute form together with the list form
of the macro for applications that require reentrant code. The execute
form of the macro stores the parameters into the storage area defined
by the list form, and generates the macro invocation to transfer control
to the service.
- ,list addr
- The name of a storage area to contain the parameters. For MF=S
and MF=E, this can be an RS-type address or an address in register
(1)-(12).
- ,attr
- An optional 1- to 60-character input string that you use to
force boundary alignment of the parameter list. Use a value of 0F
to force the parameter list to a word boundary, or 0D to force the
parameter list to a doubleword boundary. If you do not code attr,
the system provides a value of 0D.
- ,COMPLETE
- Specifies that the system is to check for required parameters
and supply defaults for omitted optional parameters.
- MONTKN=montkn
- A required input parameter which contains the delay monitoring
token.
To code: Specify the RS-type
address, or address in register (2)-(12), of a 32 bit field.
- ,MONTKN64=montkn64
- A required input parameter which contains the long delay monitoring
token.
To code: Specify the RS-type
address, or address in register (2)-(12), of a 64 bit field.
- ,PLISTVER=IMPLIED_VERSION
- ,PLISTVER=MAX
- ,PLISTVER=0
- An optional input parameter that specifies the version of the
macro. PLISTVER determines which parameter list the system generates.
PLISTVER is an optional input parameter on all forms of the macro,
including the list form. When using PLISTVER, specify it on all macro
forms used for a request and with the same value on all of the macro
forms. The values are:
- IMPLIED_VERSION, which is the lowest
version that allows all parameters specified on the request to be
processed. If you omit the PLISTVER parameter, IMPLIED_VERSION
is the default.
- MAX, if you want the parameter list to be
the largest size currently possible. This size might grow from release
to release and affect the amount of storage that your program needs.
If
you can tolerate the size change, IBM recommends that you always specify
PLISTVER=MAX on the list form of the macro. Specifying MAX ensures
that the list-form parameter list is always long enough to hold all
the parameters you might specify on the execute form, when both are
assembled with the same level of the system. In this way, MAX ensures
that the parameter list does not overwrite nearby storage.
- 0, if you use the currently available parameters.
To code: Specify one of the following:
- IMPLIED_VERSION
- MAX
- A decimal value of 0
- ,RETCODE=retcode
- An optional output parameter into which the return code is to
be copied from GPR 15. If you specify 15, GPR15, REG15, or R15 (within
or without parentheses), the value will be left in GPR 15.
To code: Specify the RS-type address of a
fullword field, or register (2)-(12) or (15), (GPR15), (REG15), or
(R15).
- ,RSNCODE=rsncode
- An optional output parameter into which the reason code is to
be copied from GPR 0. If you specify 0, 00, GPR0, GPR00, REG0, REG00,
or R0 (within or without parentheses), the value will be left in GPR
0.
To code: Specify the RS-type address
of a fullword field, or register (0) or (2)-(12), (00), (GPR0), (GPR00),
REG0), (REG00), or (R0).
- ,STATUS=status
- ,STATUS=IWMEWLMARMSTATUSGOOD
- An optional input parameter, which contains the completion status
code of the work unit. Available completion status codes (defined
in macro IWMYCON) are:
* IwmEwlmArmStatusGood(0),
* IwmEwlmArmStatusAborted(1),
* IwmEwlmArmStatusFailed(2) or
* IwmEwlmArmStatusUnknown(3)
The codes above correspond to status codes in
the OpenGroup ARM 4.0 Standard (for the meaning of the status codes
see the ARM 4.0 Standard at http://www.opengroup.org/management/arm).
The default is IWMEWLMARMSTATUSGOOD.
indicates that the work unit completed successfully.
To code: Specify the RS-type address, or address
in register (2)-(12), of a fullword field, or specify a literal decimal
value.
