Section 1: Problem Categories and Analysis
This section summarizes problem categories and analysis. It includes the
following subsections:
Diagnostic Approach
• Serially Reusable Resources
• Resource Status Indicators
Program errors faU into three major categories:
I
J
Unending loops
• Unending wait conditions
• Abnormal termination of a task or job step
The publication OS/VS2 Message Library: VS2 System Codes. outlines
problem determination procedures to be followed for each of these
problem categories. Problem determination is the activity required to
identify a failing program or hardware unit, and to determine who is
responsible for program support or hardware maintenance.
This section provides information that supplements, but does not replace or
supercede, formal problem determination procedures.
Diagnostic Approach
The difficult way to analyze a dump is to look at each address space and
task individually. looking at its request blocks and resume-PSWs to
determine what it was doing (or waiting for) at the time of the dump. The
objective of this section is to describe a diagnostic approach that will
quickly determine which task or address space is preventing normal system
operation.
One way to start debugging is to look at system and address space status
indicators. Part 1 of Figure 1 shows the control blocks that contain system
and address space indicators in effect during normal system operation. Part
2 of Figure 1 shows the control blocks containing status indicators for the
system and address spaces after an abnormal operation. Figure 1 acts as a
recall mechanism; it does not represent all the control blocks active in a
system (only one TeB on the chain is shown, for example), nor all offsets
into the control blocks. Specific values can be located in Volume 2 or
Volume 3, or on microfiche in OS!VS2 Data Areas.
Section 1 1·1
Serially Reusable Resources
Many system resources can only be used serially - that is, by only one
task at a time. A system loop or wait generally occurs because a task has
control of such 8 resource and never finishes with it or gives it up. Other
tasks that require the resource are thus unable to continue processing.
Following are some examples of serially reusable resources.
Logical Section of the Processor: The responsibility for determining
which task gets control of the processor belongs to the dispatcher. The
dispatcher's decision is based on such things as priority, dispatchability
status. processor affinity, and the presence or absence of a wait count. If.
due to an error condition, the Asee, Tea ready queue, or ready Tea
pointer is not correct, then those address spaces or tasks beyond the break
in the queue will never get control of the processor.
Channels: At anyone time, a selector channel can handle one request for
data transfer. while a multiplexer channel can handle one request per
device. Since requests are asynchronous. the system must have some
means to keep track of these requests and to schedule them for execution
when the channel or device is available. This is provided by the logical
channel queue, which consists of I/O queue elements (lOOs) that are
created as the requests are generated.
Storage: There is actually a two-level competition for storage:
~ardware
and software. The channels compete with each other and with the
processor; any channel has priority over the processor, and the channels
have priority with respect to each other. It is possible for a hardware error
in a channel to prevent a channel operation from finishing; if that operation
has already disabled the processor. preventing references to storage, the
further execution of instructions is impossible. The system light stays on
continuously. and the system fails to enter the manual state when the STOP
button is pressed. System reset clears this condition, which cannot be
accurately detected from a dump alone.
The software competition involves control of both real and virtual storage.
OS/VS2 handles this competition in a manner that prevents lockouts and
permits the execution of tasks that have control of the storage they require.
Miscellaneous Resources: Many OS/VS2 functions require that resources
be used serially to preserve the integrity of data and to ensure normal
operation. Examples of these functions are allocating and unallocating
devices. dispatching work using the TCB queue, updating of VTOCs. using
the catalog and system data sets; writing to the operator; and so forth. The
system provides for these functions in two ways: 111 The ENO and OEO
macro instructions are used to construct control blocks IOCBs and QELs)
that indicate the name of the resource, the task requesting it. and whether
the request is for shared or exclusive use of the resource. For exclusive
requests. only the first-queued task is allowed to execute. If a task requests
exclusive control of several resources. it is not allowed to execute until it
has control of all of them. (2) locks are used to serialize the use of control
blocks associated with the dispatching of work. For example, the local lock
is used to serialize the use of the TCB.

Resource Status Indicators
)
Figure 2 defines a simple but logical approach to determining the current
use of serially reusable resources. The following text is a list of the more
important resources, and associated status indicators. (For a list of
ENQ/DEQ names. associated resources, and requesting modules, refer to
the serialization summary in Section 5,)
Processor Resources

2. Current Tea (task control block)
• The PSATNEW!PSATOlD field of the PSA is a'doubleword
new/old Tee pointer. (If the old
SRB has been dispatched.)

pointer, PSATOLD, is zero, an
• If the TCBRBP field of the TCa points to itself (instead of an AB),
then the Tca is the pseudo-wait TCB and is not chained to any
other TCB.
3. TCB Chain (by priority for each address space)
• Location 4C hex points to the CVT.
• The CVTASVT field of the CVT points to the ASVT.
• The ASVTENTY field of the ASVT begins a series of one word
entries that point to ASCBs (one for each active ASID).
• The ASCBTNEW field of the ASCB points to the first ready TCa on
the ready TCB queue. When no ready tasks exist, ASCBTNEW
points to the last TCB. This pointer is never zero (applies to
MVS/System Extensions).
• The ASCBASXB field of the ASCa points to the ASXB.
• The ASCBTCBS field of the ASCB in the number of ready TCBs not
requiring the local lock. (applies to MVS/System Extensions).

the common mother.
• The error task TCa is the only TCB without a mother TCB. In an
address space created by a START, MOUNT, or LOGON request.
the error task is the region control task (ACT).
5. Dispatching
• Task dispatchabiJity flags are in the TCaFlGS4 and TCBFlGS5 fields
of the TCB. If any bit in these two bytes is set to one, the TCa is
nondispatchable. (If bit 7 of TCBFLGS5 is set to one, the reason for
nondispatchability is indicated by a flag bit set to one in the
TCBNDSP1. TCBNDSP2. or TCBNDSP3 field of the TCB.
• Tasks ara dispatched based on the prioflty of the address space
and then on the priority of the tasks within the address space.
• Dispatching is in the following four levels.
-
Global SAB dispatcher (first).

Interactive Problem Control System - IPeS
The OS/VS2 MVS Interactive Problem Control System (IPeS) Selectable
Unit (SUS7) provides MVS installations with expanded capabilities for
diagnosing software failures and facilities for managing problem information
and status.
IPes includes facilities
for:
Online examination of storage dumps.
Analysis of key MVS system components and control blocks.
Online management of a directory of software problems that have
occurred in the user's system.
Online management of a directory of problem-related data, such as
dumps or the output of service aids.
IPCS runs as a command processor under TSO, allowing the user to make
use of existing TSO facilities from IPCS, including the ability to create and
execute command procedures (CLISTs) containing the IPCS command and
its subcommands.
IPCS supports three forms of MVS storage dumps:
• High-speed stand-alone dumps produced by AMDSADMP.
• Virtual dumps produced by MVS SDUMP on SYS1.DUMPxx data sets.
• Virtual dumps produced by MVS SDUMP on data sets specified by the
SVSMDUMP 00 statement, when the Dumping Improvements
Selectable Unit (SU33J is installed.
For information about IPCS. refer to the OS/VSl MVS In/ernerhY! Problem
Control System (IPCS) Use,'s Guide and Reference.
Function Summary
)
Figure 3 lists debugging and debugging-related facilities by type and
function. For each function, the text describes the role of each facility listed
in the figure. The figure identifies publications where each facility is
described in detail.
Dumping
Dumping functions are of five types:
)
• SNAP dumps
• ABEND dumps
• SVC dumps
• Stand-alone dumps
• SPZAP dumps

Suction 2 2-1
Snap Dumps
The SNAP macro instruction dumps a specified task to a specified data set.
The SNAP macro instruction can be used with various operands that govern
the content of the dump.
For JES3, RJPSNPS spools the channel-end data to the JES3 queue
volumes and prints this data at termination. CBPRNT snap dumps control
blocks of JES3 and MVS. DEBUG snap dumps selected JES3 control blocks
to the DEBUG data set.
Abend Dumps
Functions are provided by:
• SYSABEND, SVSMDUMP, SYSUDUMP, and JESSADMP (DO

• IEAABDOO. IEADMPOO, and IEADMROO (SVS1.PARMUB members)
• AMDPRDMP (service aid)
• CHNGDUMP and CANCEL (operator commands)
• ABEND. CALLRTM. and SETRP (macro instructions)
SYSABEND. JESSADMP, SVSMDUMP or SVSUDUMP (DD statement):
• Defines a data set to contain an ABEND dump.
IEAABDOO (SYS1.PARMlIB member):
Defines content options for SVSABEND dumps. In effect. these
options are added to options specified in ABEND, CAllRTM, and
SETRP macro instructions. Unless changed by the installation,
IEAABDOO defines dump options as
5 DATA = (LSQA.ENQ.CB.TRT.DM.IO.ERR). PDATA = (ALLPDATA). A
dump defined by these options alone would include the local system
queue area (lSQA, SUB POOL 229 and 230). ENO control blocks (ENO)
and other control blocks (CB) for the terminated task, the GTF or
system trace table [TRT), data management control blocks (OM), I/O
control blocks (10). recovery/termination error control blocks (ERR).
the PSW. registers. save area trace, pack and link pack areas. and
virtual storage subpools 0-127,252 for the terminated task
(ALLPDATA).
IEADMPOO (SVS1.PARMUB member):
Defines content options for SV5UDUMP dumps. In effect these
options are added to options specified in ABEND. CAllRTM. and
SETRP macro instructions. Unless changed by the installation,
IEADMPOO specifies the same options as IEAABDOO, with these
exceptions: LSQA and 10 are omitted.
IEADMROO (SV51.PARMLIB member);
• Defines SVC dump options for SY5MDUMP dumps. SYSMDUMP
dumps are unformatted ABEND dumps that can be formatted by
AMDPRDMP service aid. In effect these options are added to options
specified in ABEND. CALLRTM. and SETRP macro instructions. Unless
changed by the installation, IEADMROO specifies
SDATA (NUC,SOA.LSQA,SWA,TRT,RGN).
=
CHNGDUMP (operator command):
• Changes the dump content options originally specified in
SV51.PARMUB, in the system option list. The options override or are
added to the options specified by the ABEND. CALlRTM. SETRP
macros. and the associated parmlib member. The changes remain in
effect until a re-IPL. or until changed by a subsequent CHNGDUMP
command.
CANCEL (operator command):
• Cancels a job or TSO terminal session.
• Abnormally terminates the current job step.
• Optionally requests an ABEND dump.
2-2

"CANCEl (JES3 operator command):
Cancels a JES3 dynamic support program.
• Abnormally terminates the job step.
• Provides an optional ABEND dump.
·FAll (JES3 operator command):
• Terminates a JES3 dynamic support program.
• Used when a program fails to respond to -CANCEL
• Provides an optional ABEND dump.
"DUMP (JES3 operator command):
• Forces a dump of the global processor.
AMDPRDMP (service aid - MVS problem program):
• Formats and prints the unformatted ABEND dump contained in the
data set specified by the SYSMDUMP DO statement.
ABEND (macro instruction):
Abnormally terminates the current task and its subtasks or (optionally)
all the tasks for the current job step.
Optionally requests an ABEND dump for all terminated tasks.
Optionally specifies dump content options.
CALLRTM (macro instructionl:
• Invokes the recovery termination manager for a task or an address
space.
• Optionally requests an ABEND dump for all terminated tasks.
• Optionally specifies dump content options.
SETRP (macro instruction):
• Sets return parameters for return to the recovery termination manager
by the FRR or ESTAE/ESTAI routine.
• Optionally requests an ABEND dump for all terminated tasks or for the
current task if a retry is to be performed.
• Optionally specifies dump content options.
SVC Dumps
Functions are provided by:
• DUMP system parameter
• SYS1.DUMPnn data sets
• SDUMP macro instruction
• CHNGOUMP, DUMP, and SLIP operator commands
• AMDPROMP service aid
DUMP (system parameter):
• Specifies virtual address spaces to be dumped to specified data sets.
• Specifies whether SYS1.DUMPnn data sets are available to the
system.
• Specifies whether SVS1.DUMPnn data sets are on tape, on direct
access storage, or both.

The purpose of this page is to present an example of the
high-density dwnp format supported for SNAP and ABEND
dumps printed on a 3800 printer.
The dump contents are unchanged; only the format of
storage dumps lines have changed.
Each line contains
a 6 digit address. A maximum of 16 fullwords of storage
can be formatted in the 4 four-word pieces. The £u11words are followed by an EBCDIC translation (up to 64
characters in length), separated into two 32 character
portions. 'l'he first digit of each fullword of storage
is underlined.

word of storage.
A sincle letter (R or V) indicating whether
t.he address is real absolute or virtual • .1.
,r-A-n-a:-b-so""'l'-u-'t-e-ad-d-=-r-e-s-s-is an address to which prefixing
has been applied. Prefixing is described in GA22-7000; in
effect, it simply interchanges the 4K bytes of storage at
real address 0 with the 4K bytes of storage at the real
:t.ddress contained in the prefix register. Prefixing is
applied to all references to real storage and to keys in
storage, except for references to the PSA. during a S'l'ORE
srATUS operation, and except for references by a cbannel
to extended. logout locations, to indirect-data-address
fJords, and to CCWs.
Virtual addresses correspond to tile address space current
at the time of the STORE STATUS operation for the processor
on which the stand-alone dump program was IPLed. If the
STORE STATUS operation was not performed, virtual addresses
correspond to the master scheduler address space.
Note:
As printed in the dump, virtual address zero
corresponds to abSOlute address zero. The corresponding
real address is not zero, but the address contained in the
prefix register.
Each line of print includes:
•
•
o
The virtual address of the first
printed word of storage.
Eight words of storage in hexadecimal format.
The same eight words in EBCDIC format, with
periods representing characters other than
blank, A-Z, 0-9.

PROCESSOR TIMER -- Processor timer value (hex).
CLOCK-COMP -- Clock comparator value (hex).
PREFIX -- Prefix register (hex).
NOTE: If you do not perform a STORE STATUS
operation, only the general-purpose registers
appear; other items in the above list are not

registers.
1Data area acronym and address, followed by for;rnatted
fields.
Each line of print includes:
The offset of the first printed field, relative to the
oeginning of the data area.
The name of each printed field (minus the d.ata area
acronym) and the contents of the field in hexadecimal
format. In the CSD, for example, the printed name
"CPUJS" identifies the CSO field CSDCPUJS.
(The
printed name "RESV" indicates that the field is
reserved and contains no useful data.)
For a description of each printed field, see the

are as follows:
Contents
CURRENT PSW hhhhhhhh hhhhhhhh -- Current program status
word (current when the dump was taken). 1
Register contents in hexadecimal format: 1
GPRS 0-7, GPRS 8-F
CTRS 0-7, CTRS 8-F
FPRS 0-2, FPRS 4-6
General purpose regist£:rs.
Control registers.
Floa ting-point registers.
Contents of real storage.
Q
Each line of print includes:
The real (absolute) address of the first printed word of
storage. 2
• The storage protection key.
• Eight words of storage in hexadecimal format.
• The 'same eight words in EBCDIC format, with periods
representing characters other than blank, A-Z, and 0-9.
'NOTE: If you do not perform a STORE STATUS operation,
only the general purpose registers appear.
2An absolute address is a real address to which prefixing
has been applied. Prefixing is described in GA22-7aOO ~
in effect, it simply interchanges the 4K bytes of
storage at real address 0 with the 4K bytes of storage
at the real address contained in the prefix register.
Prefixing is applied to all references to real storage
and to keys in storage, except for references to the
PSA during a STORE STATUS operation, and except for
references by a channel to extended logout locations, to
in~~re::.t-data-address words, and to CCWs.

IPL: "Not operationa'" is the status of the volume containing the nucfeus
being loaded.
IPL: An I/O operation was not initiated; CSW was stored: channel was not
busy,
IPL: An I/O operation was not initiated because a "not operationsl"
response wss received from a SID instructicm; CSW wss not stored;
channel was not busy.
IPL: An I/O operation waa not initiated: CSW was not stored; channel was
not busy after execution of a Test I/O instruction.
IPL: A unit check caused an I/O interruption; the address of the CCW is
placed in location X'4C': the first four unit-check sense bytes are placed
in location X'54'.
IPL: A interface control check. or channel control check. or channel data
check. or program check,. or channel chaining check occurred.
NIP: A console was not available.
NIP: A catalog entry for the SvSl.UNKUB data set was not found on or
not retrievable from the system catalog.
The master scheduler terminated abnormally during initialization; a dump
was taken to the SYS1.0UMPxx data set.
IPL: An active nucfeus member is not edited in the scatter format; the
nucleus cannot be loaded.
The master scheduler terminated abnormally during initialization; no dump
was taken.
IPL: The SYS1.NUCLEUS data set or active member, IEANUCOx. of
SYS1.NUCLEUS ia not found on the IPL volume: the system nucleus
cannot be located'.
IPL: An IPLed volume does not contain the IPL text.
NIP: An error occurred from which recovery waa impossible.
Recursive translation exceptions occurred due to incorrect: Initialization, or
overlaying of the master address apace segment tables or common
page tables occurred.
IPL: A unit check occurred following a successfully started I/O operation.
IPL: The nucleus ia too big for the machine size; the space availabfe for
relocation dictionary records waa exceeded.
IPL: An unexpected program interruption occurred.
An attemPt was made to execute multiprocessing modules that were not
included in the nucleus when the system was generated.
The error condition specified on a SUP command has been met and the
system is placed in a ''wait state", as requested.
Supervisor control suffered a double recursive abnormal termination in
supervisor control auper FRR.
NIP: An I/O error occurred on the main consola following an EXCP
operation.
A page fault occurred for a duplexed page but primary and secondary
devices are either in a quiesced or "not RIoIdy" state.
The system termination facility failed to receive the" expected interruption
while attempting to write record to the SYS1.LOGREC data set.
Either a power Interruption occurred or the operator replied "REST'" to the

Section S: General Reference
This section provides general reference infonnation useful for debugging
purposes. There ate eight subsections:
SVC Summary
defines tho five types of sve routines, briefly describes the sve table,
summarizes system-defined sve instructions, and lists the sve's and
associated macros.
SVSEVENT Summary
describes system events causing entry to the system resources
manager (SAM) by a direct branch or SVC 95.
Modulo Summary
identifies. for each three-character module-name prefix. the
corresponding system component and program logic manual. (Where
the module-name prefix is also a system message number. the
appropriate message manual is also identified.)
Component Summary
identifies the component microfiche, the modules that belong to the
component, and the program logic manual that provides primary
documentation.
Storago Summary
briefly describes the layout of real and virtual storage, the use of
storage protection keys, and the meaning of virtual storage subpools.
• Serialization Summary
describes the use of locks and ENQ/DEQ names.
• General System Flow
describes generalized control ftow among system components.
• Acronyms
defines commonty used acronyms. For each acronym that identifies
data area, the definition includes a reference to the mapping macro
and to the publications that describe the data area.

SVC Summary
This summary defines the five types of SVC routines, briefly describes the
SVC table, and summarizes each'system-defined SVC instruction.
SVC Routine~
There arB five types of SVC routines, which are distinguished as follows:
Rosidence: Types 1. 2 and 6 SVC routines are part of the nucleus; types 3
and 4 SVC routines reside in the link. pack area. A type 3 routine is a single
load module, while a type 4 routine consists of two or more load modules.
Naming Conventions: Types 1, 2 and 6 SVC routines are named IGCxxx,
where xxx is the SVC number (decimal). Types 3 and 4 SVC routines are
named IGCyyxxx, where xxx is the SVC number and yy is the number of the
load, beginning with 00 for the first (or only) load.
For types 3 and 4 SVC routines, th& internal format of the SVC number
(xxxi is a zoned decimal with a four-bit sign code (1100) in the low-order
position. Because of the sign code, a low-order digit between 1 and 9
corresponds to an EBCDIC character between A and I; a low order zero
corresponds to an EBCDIC opening brace' {'. Since an opening brace is not
included in most character sets, a low-order zero is usually entered as a
12-0 punch and printed as a blank.
Section 5 5-\
Register Conventions: SVC routines are entered with the following data
in the general purpose registers:
Registers 0.1.13. and 15 - Contents when the sve instruction was executed.
Register 3 - Address of the CVT.
Register 4 - Address of the TCB.
Register 5 - Address of the current RB Ifor type 1 SVe). or address of the SVRS
for sve routine Ifor type 2. 3, 4, or 6 SVe).
Register 6 - Address of the sve routine entry point
Register T - Address of the AseB.
Register 14 - Return address.
Other registers - Unpredicteble
Locks: Each SVC routine is entered with the locks specified for the routine
in the BVe table. In addition. each type 1 BVe routine is entered with the
LOCAL lock. whether or not it is specified in the sve table; this lock must
not be released. An sve routine can acquire any lock. and runs enabled or
disabled dependi_ng on the lock held. To avoid disabled page faults. a type
3 or 4 sve routine must fix its pages in real storage before acquiring a
disabled lock (any lock other than LOCAl, eMS. or eMSEQOQ). A type 6
sve may not be suspended for a lock request (applicable to MVS/System
Extensions).
Page Faults: An sve routine can be restarted after a page fault. provided
that the routine does not hold a disabled lock.
SVC Instructions: An sve routine can issue SVC instructions. provided
that it does not hold any lock. (NoM': A type 1 sve routine cannot issue
BVe instructions. because it always holds at least the LOCAL lock.)
Other Characteristics: All sve routines are entered in supervisor state
with a zero storege protect key (other keys may be used during execution).
Use of an sve routine is authorized or unauthorized. as specified in the
sve table. A type 6 sve executes disabled and must not enable (applicable
to MVS/System Extensions).
.
SJ'CTabl.
The sve table is a system data area that contains one eight-byte entry for
each system-defined or user-defined BVe instruction. Each entry contains
the following information.
•
•
•
•
The entry-point address of the sve routine.
The BVe type (1. 2. 3. 4. or 6).
The function code (authorized or unauthorized).
The locks to be acquired by the BVe first level interruption handler
before the sve routine is executed.
.
The format of an sve table entry is described under "SVCTABLE" in the
"Data Area Descriptions" portion of Volume 3.
Sy.t.m SJ'C In.tnIctlolU
For each BVe. this summary provides the following information:
• The sve instruction in assembler language and machine language
(hexadecimal).
Exampl.: SVC 16 (OA10l
• The macro instructions that generate the sve instruction.
• The sve type (1. 2. 3. 4. or 6).
• Locks acquired by the sve routine or by the sve first level
interruption handler.
• The object module containing the entry point of the BVe routine.
• The applicable PLM which describes the SVC's operation.
• APF protected. if applicable. (Unless otherwise noted. the sve in
question is not APF protected.)
• GTF trace data:
- Information passed to the BVe routine in general registers 15. O.
and This includes the extended BVe routing codes for BVe 109.
sve 116. and sve 122.
- Additional information displayed in GTF comprehensive trace
records (but omitted in GTF minimal trace records). For complete
GTF record formats. refer to "sve Trace Records" in Section 3.

For each 2K block of real storage, there is 8 seven-bit control field called
"key in storage." This key is used as follows:
B
Access Control Bits: Bits 0-3 are matched against the four-bit protection
key in the PSW whenever information is stored. or whenever information is
fetched from a location that is protected against fetching.
In OS/VS2. the 16 protection keys provided by the PSW (arid matched
against tha accass control bits) are assigned as follows:

Fetch Protactian Bit: Bit 4 indicates whether protection applies to
fetch-type references. A zero indicates that only store-type references are
monitored. and that fetching with any protection key is permitted; a one
indicates that protection applies to both fetching and storing. No distinction
is mede between the fetching of instructions and the fetching of operands.
Reference Bit: Bit 5 is associated with dynamic address translation. It is
normally set to one each time that a loca'tion in the related 2K storage block
is referred to either for storing or for fetching of Information.
Change Bit: Bit 6 is also associated with dynamic address translation. It is
set to one each time that information is stored into the corresponding 2K
block of storage.

Storage Subpools
A subpool is a group of logically related storage blocks identified by a
subpool number. In a request for virtual storage. a subpool number
indicates the type of storage that is requested_ The meaning of each

Serialization Summary
This summary describes the use of locks and system ENQ/DEQ names.
Lock Summary
In OS/VS2, the set of locks is categorized. by hierarchy (from highest to
rowestl 85 follows:
DISP
Dispatcher - serializes certain global functions and storage in addition to
ASM
SALLOe
IOSYNCH
users of the global intersect (applies to MVS/System Extensions).
Auxiliary storage management - serializes auxiliary storage resources.
Space allocation - serializes the resources of real storage management
(RSM) and virtual storage management (\ISM). and some auxiliary
storage management resources.
I/O supervisor synchronization - serializes the IDS purge function and
other lOS resources.
IOSCAT
IDS channel availability table lock. - serializes lOS processor related seve
area.
IDS unit control block lock • serializes access and updates to the unit
control blocks. There is one lock per UCB.
10SlCH
IDS logical channel Queue lock - serializes access and updates to the
IDS logical channel Queues. There is one lock per channel Queue.
SRM
System resources manager lock· serializes the use of SRM control
blocks and associated data.
CMSEQDQ ENQ/DEQ Cross Memory Services - Serializes ENQ/CEQ functions and
the use of tha ENQ/DEQ control blocks. (As applicable to MVS!System
Extensions.)
CMS
General Cross Memory Services· this lock is used by all other global
functions. (As applicable to MVS/System Extensions.)
LOCAL
Local Memory· serializes the memory related resources and users of
the local intersect. (As applicable to MVS/System Extensions.)
10SUCB
The use of locks is based on the following considerations:
At anyone time, a processor canflold only one lock per class (as
listed above). The cross memory services category is an exception. A
processor can hold both cross memory services locks but only if they
are unconditionally requested at the same time. For each processor.
the location. (PSA.2FA) indicates the locks currently held.-• Page faults are permitted for programs that own the LOCAL and/or
CMS locks. but not for programs that own locks higher in the
hierarchy.
• When requesting the CMS lock, a program must already own the
LOCAL lock. When requesting any other lock. a program need not own
locks that are lower in the hierarchy.
• Locks can be requested conditionally or unconditionally. However. only
locks higher than those currently held by the processor can be
requested unconditionally.
Tho following table lists the class. type. location and PSACLHS bit of each
lock.

is pointed to by PSA location. PSA+2FC hex.
- For each processor, the PSACLHT field (PSA + 280 hex) contains the
addresses of the ASM and lOS locks currently held.
Each lock is a ful1word of storage. If the lock value is zero, the lock is
available (that is, not owned). For owned locks, lock contents and
descriptions are listed below.

field of the ASca is turned on and the cross memory seNices lock-held
indicator in the PSAHLHI field of the PSA is turned off until the address
space is redispatched. The ASCB address remains in the CMS lock
and/or the CMSEOOQ lock until they are released.
For more complete information. refer to OS/VS2 System Logic Library For
information about the use of locks by SVC routines, refer to the SVC
summary earlier in this section.
