Parameters

The parameters are explained as follows:

name

An optional symbol, starting in column 1, that is the name on the IWMRESET macro invocation. The name must conform to the rules for an ordinary assembler language symbol.

ASID=asid

A parameter which contains the address space identifier (ASID) of the job you want to change.

To code: Specify the RS-type address, or address in register (2)-(12), of a halfword field.

,FUNCTION=RESET

,FUNCTION=QUIESCE

,FUNCTION=RESUME

An optional parameter, which indicates the function to perform against the job. The default is FUNCTION=RESET.

,FUNCTION=RESET

Requests that the job's service class or performance group be changed.

,FUNCTION=QUIESCE

Requests that the job be quiesced. If the job is non-swappable, it is given the lowest possible performance characteristics.

,FUNCTION=RESUME

Requests that the job be reclassified according to the service policy in effect. This undoes a prior request to reset the job to a particular service class, or to quiesce the job.

JOBNAME=jobname

A required input parameter which contains the jobname of the job you want to change. If there is more than one executing job with this jobname, you must specify the ASID parameter to identify the specific job.

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)

,MF=(E,list addr,NOCHECK)

,MF=(M,list addr)

,MF=(M,list addr,COMPLETE)

,MF=(M,list addr,NOCHECK)

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.

Use MF=M together with the list and execute forms of the macro for service routines that need to provide different options according to user-provided input. Use the list form to define a storage area; use the modify form to set the appropriate options; then use the execute form to call the service.

IBM® recommends that you use the modify and execute forms of IWMRESET in the following order:

• Use IWMRESET ...MF=(M,list-addr,COMPLETE) specifying appropriate parameters, including all required ones.
• Use IWMRESET ...MF=(M,list-addr,NOCHECK), specifying the parameters that you want to change.
• Use IWMRESET ...MF=(E,list-addr,NOCHECK), to execute the macro.

,list addr

The name of a storage area to contain the parameters. For MF=S, MF=E, and MF=M, 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.

,NOCHECK

Specifies that the system is not to check for required parameters and is not to supply defaults for omitted optional parameters.

,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; 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

,PRODUCT=product

A required input parameter, which contains the product name that is requesting the job be changed. The product name is included in the SMF 90 subtype 30 record created by IWMRESET.

To code: Specify the RS-type address, or address in register (2)-(12), of an 8-character field.

,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).

,SRVCLASS=srvclass

When FUNCTION=RESET is specified, a required input parameter which is the service class to be assigned to the job. Resetting to a new service class also resumes quiesced work.

When you reset a server to a new service class, the goals associated with that service class are ignored. However the resource group associated with the new service class is honored. The one exception where the goal for a server is honored is when the transactions it is serving have been assigned a discretionary goal.

To code: Specify the RS-type address of an 8-character field.

,USERID=userid

A required input parameter, which contains the ID of the user who is requesting the job be changed. The user ID is included in the SMF 90 subtype 30 record created by IWMRESET. If there is no user ID available, the caller should pass blanks.

To code: Specify the RS-type address, or address in register (2)-(12), of an 8-character field.
