EXEC LSERV From the reader:

II JOB jobname 1/ EXEC LSERV

,. ,&

LSERV can also be executed in a real partition. The output of LSERV shows the contents of the label cylinder on the device assigned to SYSRES. The output is directed to the device assigned to SYSLST.

When and How to use

1. Operator action given in DOS/VSE Messages indicates when LSERV must be executed.

Programmer action, also given in DOSIVSE Messages, explains how to U$e the LSERV printout.

For example, under the message:

OP36NO REC FND

2. It is wleful to execute LSERV prior to running a program that is known to have been run some-time in the past, but whose workfile assignments and partition allocations are unknown.

3. LSERV can be used for error analysis. LSERV displays the TLBL and the DLBL and EXTENT information contained on the SYSRES label cylinder. Information about secured data files is not displayed.

Summary of information provided

The printout of LSERV will show you the foHowing details about the previous run:

• Whether the correct DLBL/EXTENT information is stiH on the label cylinder

• The permanent files

• The temporary files

• Extent type

• File type For more information,

Refer to OOS/VSE Serviceability Aids and Debugging Procedures (GC33-5380).

SUPERVISOR MACROS Supervisor Macro Instruction Operation

Describe the Hardware Features Operation Operand CONFG

FP={~~S}

MODEL = mod number

Explanation

Indicates whether the supervisor is to support American National Standard Code for Information Interchange (ASCII). YES adds 512 Bytes to the supervisor size.

YES must be specified if mixed parity tape process-ing is required for the emulators, the tape prepro-cessor and the tape postproprepro-cessor programs.

Specifies whether the Supervisor Select option is to be used. By specifying an alphameric character (A·Z, 1-9), a unique name will be assigned to the supervisor being generated. For example, ID=A generates a supervisor named $$A$SUPA. [t this parameter is omitted the supervisor will be named

$$A$SUP1.

Indicates support for magnetic ink or optical character reader/sorters .. The specification 14 indi-cates support for 1419s with Single Address Adapter, 1255s, 12595, or 1270s. 1419D specification gives support for 14195 with Dual Address adapter, or 12755. Burst mode and MICR devices cannot run concurrently on the same byt multiplexor channel.

Specifies whether 370 or 4300 hardware is supported.

Specifies the number of partitions to be supported.

The minimum is 2. The maximum value for N is 5.

The default value is 3.

Specifies that paging activity is to be controlled by means of the macros PAGEIN, RELPAG, and FCEPGOUT. The value n indicates the maximum no. of page·in requests that can be queued for execution. Each PAGEIN macro issued in a program represents a page-in request. To obtain the support for the 3 macros, the value n must be 1 or higher.

Although the maximum number is not restricted, n should not exceed 15.

Specifies whether the entire RMS (MCAR, CCH, and RMSR) is to be generated. RMS=YES is required if the string switch feature is installed.

If RMS=NO is specified and TP:VTAM, then RMS=YES is forced.

Specification of VTAM forces AB=YES, FCPREAL

=YES, IT=YES, OC=YES, PC=YES, PFIX=YES, AP=YES, TOD=YES, WAITM=YES, and for Models 115 and 125 RMS=YES.

Specify the model number of the processor.

PRTY=(partion. partition. '

Explanation

Specifies whether output to a console printer assigned as SYSLOG is to be buffered. n sp'ecifies the number of buffers to be generated. Accepted values are from 1 to 50. An invalid specification causes one buffer to be generated.

Specifies support for protection of DASD files, where nl,n¹ indicates the whole range of channels to which the devices may be attached. Specification or nl,nl provides file protection for disk devices.

Only valid in 370 mode.

Specifies whether support is required for Display Operator Console (DCC). The necessary supervisor routines are generated to allow to assign $YSLOG either to a 1250 or 1 3277. The default taken is dependent on the CPU model number as specified by the MODEL parameter of the CONFG macro.

[f MOOEL=115, or 125, 1250 will be used as a default. If MODEL=138. 148. 158.3011, or 4300, 3277 will be the default. For any other MODEL the default will be NO.

Note: A Display Operator Console must not be attached to the same selector or multiplexor channel as SYSRES.

Specify the number of entries for the error queue.

With multiprogramming support n may be from 5 to 50. Lhe lower value is the default value in each case.

Specifies support for error by volume analysis for 2400 and 3400 series tapes. r is the read error threshold. w is the write error threshold.

Specifies whether fast CCW translation is to be supported. Specifying FASTTR=YES affects the maximum, minimum and default values of BUFSIZE=n in VSTAB.

Generates Job Accounting I nterface support. YES specifies basic support (SIOs not counted).

(n1,n2,n3, ... ) specifies the number of devic es per partition for which SIOs are to be counted.

The maximum value of n for any partition is 255;

the default value is 0.. n1 always specifies the number for the background partition. The parti-tions to which n2.n3 ... refer depend on the number of partitions in the system_ The table below shows the pattern for partition association to values n2 through n5. job-accounting routines. The maximum acceptable value is 1024 and the default value is 16. n2 spe-cifies the number of bytes for the alternative label area. The maximum value is 244 and the default value is 0_

Specifies the dispatching priorities of partitions in ascending order. The number of operands must be

TEBV={~}

TRKHLD={~}

TT1ME= {partition

Explanation

Provides support for the .Rotational Position Sens-ing (APS) capabilities of DASD devices supporting the feature.

Specifies the number of entries in the Second Level Directory,'The minimum value for n is 5. This value is assumed in the case of an incorrect specification.

A performance decrease will result if the number spe-cified is less than the number of actually used direc-tory tracks of the System Core Image Library. An upper limit for CKD is 1 B. for FBA it is 30. although the number is not restricted.

Specifies whether the synchronous exit function is to be supported. SYNCH=YES should be specified if problem programs use the synchronous exit facility (SVC screening) to support multiple users in one ~artition.

Specifies if system input and system output files (SYSRDR, SYSIPT, SYSLST,'SYSPCH) in any partition may be assigned to a disk device or dis-kette, or if extended support for the procedure library is desired. Specification of YES gives sup-port for all disk devices including diskette. nl indi-cates the residual capacity fin records) for begin-ning of operator notification when SYSLST is assigned to a disk device. n2 indicates the same for SYSPCH. Acceptable values for n1 and n2 are from 100 to 65535; if either is omitted, 1000 is assumed.

For diskette this notification is not supported.

Specifies whether individual (I R) or combined (CR) recording of error statistics is required for unlabeled or nonstandard 2400 or 3400 series tapes.

Specifies whether the Track-Hold feature is to be supported for DASD in a supervisor that supports multiprogramming. n indicates the maximum no.

of tracks/blocks to be held at anyone time.

Accepted values are from 1 to 255. A Track-Hold Table (THTAB) with n entries is generated in the supervisor. An invalid specification results in 10 entries being generated. The NPARTS parameter in the SUPVR macro must specify more than one partition if TAKHLD= n is specified.

Specifies whether the timer is to be supported and if so, the partition owning the task timer. Only one partition I D can be specified. The partition tD is BG or Fn (where n is one of the foreground parti-tions generated into the system). If the partition ID sequence does not correspond to the appropriate NPARTS specification, or if the value specified for NPARTS is invalid, an MNOTE is issued.
