Parameters
The parameters are explained as follows:
- name
- An optional symbol, starting in column 1, that is the name on
the IWMSRSRG macro invocation. The name must conform to the rules
for an ordinary assembler language symbol.
- ,HEALTH=health
- ,HEALTH=NO_HEALTH
- An optional input parameter, which contains the health factor
associated with the address space. This is a value, that reflects,
up to which percentage this address space is capable to handle requests.
NO_HEALTH indicates that no health indicator was passed. This is the
default. In this case, a health value of 100 is assumed, when the
server is registered.
To code: Specify
the RS-type address, or address in register (2)-(12), of a fullword
field.
- ,HOST=host
- ,HOST=NO_HOST
- An optional input parameter, which contains the host name associated
with the address space to be registered. The value should be padded
on the right with blanks for any unused characters. NO_HOST indicates
that no host name was passed. This is the default.
To
code: Specify the RS-type address, or address in register (2)-(12),
of a 64-character field.
- LOCATION=location
- A required input parameter, which contains the server LOCATION
associated with the address space to be registered. The value should
be padded on the right with blanks for any unused characters.
To code: Specify the RS-type address, or address
in register (2)-(12), of a 18-character field.
- ,LUNAME=luname
- A required input parameter, which contains the server Logical
Unit name associated with the address space to be registered.
To code: Specify the RS-type address, or address
in register (2)-(12), of an 8-character field.
- ,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.
- ,NETWORK_ID=network_id
- A required input parameter, which contains the Network ID associated
with the address space to be registered.
To code: Specify
the RS-type address, or address in register (2)-(12), of an 8-character
field.
- ,PLISTVER=IMPLIED_VERSION
- ,PLISTVER=MAX
- ,PLISTVER=0
- ,PLISTVER=1
- ,PLISTVER=2
- ,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:
USERDATA
- 2, which supports the following parameter
and those from version 0 and 1:
HOST
- 3, which supports the following
parameter and those from version 0, 1 and 2:
HEALTH
Note:
The PLISTVER=3 option can only be used on systems running z/OS® V1R7 with OA14310 installed,
and on systems running z/OS V1R8
or higher.
To code: Specify one of the following:
- IMPLIED_VERSION
- MAX
- A decimal value of 0, 1, 2, or 3
- ,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).
- ,STOKEN=stoken
- A required input parameter, which contains the space token of
the server to be registered.
To code: Specify
the RS-type address, or address in register (2)-(12), of a 64-bit
field.
- ,USERDATA=userdata
- ,USERDATA=NO_USERDATA
- An optional input parameter, which contains data
meaningful to the user of this service. This user data is available
to callers of the IWMSRSRS service.
The format is undefined
to MVS™. The default is NO_USERDATA,
which indicates that no user data was passed.
To
code: Specify the RS-type address, or address in register (2)-(12),
of a 64-character field.
