Parameters
The parameters are explained as follows:
- name
- An optional symbol, starting in column 1, that is the name on
the IWMMEXTR macro invocation. The name must conform to the rules
for an ordinary assembler language symbol.
- ,ABNORMAL_COND=abnormal_cond
- An optional output parameter, which contains the current information
about abnormal conditions which were either recorded in the input
monitoring environment or which were propagated to it via IWMMXFER
Function(Return). Multiple conditions may exist.
The mask, Iwmmabnl_Scope_LocalMVS,
may be used to determine whether an abnormality which only affects
work on the current MVS™ image
was recorded.
The mask, Iwmmabnl_Scope_Sysplex, may be used
to determine whether an abnormality which affects work on all MVS images in the sysplex was recorded.
To
determine whether a condition was recorded, merely AND the field supplied
for ABNORMAL_COND with the relevant mask. The result will be nonzero
when the condition is true, zero when the condition is false.
To code: Specify the RS-type address, or address
in register (2)-(12), of a 32 bit field.
- ,ARRIVALTIME=arrivaltime
- An optional output parameter, which contains the work arrival
time in STCK format.
To code: Specify the
RS-type address, or address in register (2)-(12), of a 64-bit
field.
- ,ASID=asid
- An optional output parameter,which contains the address
space ID. When the monitoring environment is not associated with an
address space, the output will be a halfword of binary zeros.
To code: Specify the RS-type address, or address
in register (2)-(12), of a 16-bit field.
- ,ENCLAVE_TOKEN=enclave_token
- An optional output parameter, which contains the enclave token.
When the monitoring environment is not associated with an enclave,
the output will be a doubleword of binary zeros.
To
code: Specify the RS-type address, or address in register (2)-(12),of
a 64 bit field.
- ,EWLM_CHCORR=ewlm_chcorr
- An optional output parameter, which contains the cross-platform
Enterprise Workload Management (EWLM) correlator of the work request
associated with the monitoring environment.
To
code: Specify the RS-type address, or address in register
(2)-(12), of a character field.
- ,EWLM_PACTKN=ewlm_pactkn
- An optional output parameter, which contains the cross-platform
Enterprise Workload Management (EWLM) parent correlator token of the
work request associated with the monitoring environment.
To code: Specify the RS-type address, or address
in register (2)-(12), of a character field.
- ,EWLM_S_CURCORR=ewlm_s_curcorr
- An optional output parameter, which contains the current correlator
of the work unit started by IWMMSTRT. Normally this correlator is
different from the child correlator of the work request created by
IWM4MINI.
To code: Specify the RS-type
address, or address in register (2)-(12), of a character field.
- 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.
- ,OWNER_DATA=owner_data
- An optional output parameter, which is to receive the data established
by the user/owner of the monitoring environment. The format is undefined
to MVS. When the monitoring environment
is not associated with an OWNER_TOKEN value, the output will be a
word of binary zeros.
To code: Specify the
RS-type address, or address in register (2)-(12), of a 32 bit field.
- ,OWNER_TOKEN=owner_token
- An optional output parameter, which is to receive the token
established by the user/owner of the monitoring environment. The
format is undefined to MVS. When
the monitoring environment is not associated with an OWNER_TOKEN value,
the output will be a word of binary zeros.
To
code: Specify the RS-type address, or address in register (2)-(12),
of a 32 bit field.
- ,PLISTVER=IMPLIED_VERSION
- ,PLISTVER=MAX
- ,PLISTVER=0
- ,PLISTVER=1
- ,PLISTVER=3
- 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; in this way, MAX ensures that the parameter list does not overwrite
nearby storage.
- 0, which supports all parameters except
those specifically referenced in higher versions.
- 1, which supports the following parameter
and those from version 0:
TTRACETOKEN
- 2, which supports the following parameters
and those from version 0 and 1:
ASID
ENCLAVE_TOKEN
- 3, which supports the following
parameters and those from version 0, 1, and 2:
EWLM_CHCORR
EWLM_PACTKN
- 4, which supports the following parameter
and those from version 0, 1, 2, and 3:
EWLM_S_CURCORR
To code: Specify one of the following:
- IMPLIED_VERSION
- MAX
- A decimal value of 0, 1, 2, 3, or 4
- ,RETCODE=retcode
- An optional output parameter into which the return code is to
be copied from GPR 15.
To code: Specify the
RS-type address of a fullword field, or register (2)-(12).
- ,RSNCODE=rsncode
- An optional output parameter into which the reason code is to
be copied from GPR 0.
To code: Specify the
RS-type address of a fullword field, or register (2)-(12).
- ,SERVCLS=servcls
- An optional output parameter, which contains the service class
token. When the monitoring environment is not associated with a service
class token, the output will be a word of binary zeros.
To code: Specify the RS-type address, or address
in register (2)-(12), of a 32 bit field.
- ,TRXNAME=trxname
- An optional output parameter, which contains the transaction
name. The field will be all blanks when NO_TRXNAME was specified on
IWM4MINI.
To code: Specify the RS-type address,
or address in register (2)-(12), of an 8-character field.
- ,TTRACETOKEN=ttracetoken
- An optional output parameter, which contains the transaction
trace token associated with the work request. The field will be all
zero when NO_TTRACETOKEN was specified on IWM4MINI.
To
code: Specify the RS-type address, or address in register (2)-(12),
of a 32-character field.
- ,USERID=userid
- An optional output parameter, which contains the local user
ID associated with the work request. The field will be all blanks
when NO_USERID was specified on IWM4MINI.
To code: Specify
the RS-type address, or address in register (2)-(12), of an 8-character
field.
