7 About this book This book describes the MQSeries commands (MQSC), which system operators and administrators can use to manage queue managers on the following MQSeries platforms: v Compaq (DIGITAL) OpenVMS v OS/2 Warp v OS/390 v OS/400 v Tandem NSK v UNIX operating systems v Windows NT The commands are described in alphabetic order in Chapter 2. The MQSeries commands on page 9. At the start of each command description, the platforms on which you can use the command are shown. The term UNIX systems is used to denote the following UNIX operating systems: v MQSeries for AIX v MQSeries for AT&T GIS UNIX 1 v MQSeries for Compaq Tru64 UNIX v MQSeries for HP-UX v MQSeries for SINIX and DC/OSx v MQSeries for Sun Solaris (SPARC and Intel Platform Editions) Who this book is for This book is intended for system programmers, system administrators, and system operators. What you need to know to understand this book How to use this book To understand this book, you should be familiar with the system facilities for the platform on which you are installing the MQSeries product. If you are unfamiliar with the concepts of messaging and queuing, you should read An Introduction to Messaging and Queuing. For platforms other than OS/390, read those sections of the MQSeries Administration Guide, System Management Guide, or System Administration book for your platform that relate to the task you want to perform. For OS/390, read the sections of the MQSeries for OS/390 System Administration Guide, MQSeries for OS/390 System Setup Guide, or both that relate to the task you want to perform. These books are listed in Bibliography on page This platform has been renamed to NCR UNIX SVR4 MP-RAS, R3.0. Copyright IBM Corp. 1993, 2000 vii

8 About this book When you have decided which commands you need to use, use this book to learn their syntax. The syntax of the MQSeries commands is represented in syntax diagrams. To learn how to read these diagrams, see How to read syntax diagrams on page 7. The parameters for each command are listed in the following order in the syntax diagrams: v Parameters that are required are listed first, in alphabetic order. v Parameters that are optional follow, again in alphabetic order. There is a glossary at the back of the book. viii MQSeries MQSC Command Reference

13 Chapter 1. Using MQSeries commands MQSeries commands (MQSC) provide a uniform method of issuing human-readable commands on MQSeries platforms. For information about programmable command format (PCF) commands (not available on OS/390), see the MQSeries Programmable System Management manual. This chapter describes: v Rules for using MQSeries commands v Rules for naming MQSeries objects on page 4 v How to read syntax diagrams on page 7 The general format of the commands is shown in Chapter 2. The MQSeries commands on page 9. Rules for using MQSeries commands You should observe the following rules when using MQSeries commands: v Each command starts with a primary parameter (a verb), and this is followed by a secondary parameter (a noun). This is then followed by the name or generic name of the object (in parentheses) if there is one, which there is on most commands. Following that, parameters can usually occur in any order; if a parameter has a corresponding value, the value must occur directly after the parameter to which it relates. v v v v v Note: On OS/390, the secondary parameter does not have to be second. Keywords, parentheses, and values can be separated by any number of blanks and commas. A comma shown in the syntax diagrams can always be replaced by one or more blanks. There must be at least one blank immediately preceding each parameter (after the primary parameter) except on OS/390. Any number of blanks can occur at the beginning or end of the command, and between parameters, punctuation, and values. For example, the following command is valid: ALTER QLOCAL ('Account' ) TRIGDPTH ( 1) Blanks within a pair of quotation marks are significant. Additional commas can appear anywhere where blanks are allowed and are treated as if they were blanks (unless, of course, they are inside quoted strings). Repeated parameters are not allowed. Repeating a parameter with its NO version, as in REPLACE NOREPLACE, is also not allowed. Strings that contain blanks, lowercase characters or special characters other than: Period (.) Forward slash (/) Underscore (_) Percent sign (%) must be enclosed in single quotation marks, unless they are: Issued from the MQSeries for OS/390 operations and control panels Generic names ending with an asterisk (on OS/400 these must be enclosed in single quotation marks) Copyright IBM Corp. 1993,

14 Rules for using commands A single asterisk (for example, TRACE(*)) (on OS/400 these must be enclosed in single quotation marks) A range specification containing a colon (for example, CLASS(01:03)) v v v v If the string itself contains a quotation mark, the quotation mark is represented by two single quotation marks. Lowercase characters not contained within quotation marks are folded to uppercase. A string containing no characters (that is, two single quotation marks with no space in between) is not valid. A left parenthesis followed by a right parenthesis, with no significant information in between, for example NAME ( ) is not valid except where specifically noted. Keywords are not case sensitive AltER, alter, and ALTER are all acceptable. Names that are not contained within quotation marks are converted to uppercase. Synonyms are defined for some parameters. For example, DEF is always a synonym for DEFINE, so DEF QLOCAL is valid. Synonyms are not, however, just minimum strings; DEFI is not a valid synonym for DEFINE. Note: There is no synonym for the DELETE parameter. This is to avoid accidental deletion of objects when using DEF, the synonym for DEFINE. Characters with special meanings The following characters have special meaning when you build MQSC commands: Blanks are used as separators. Multiple blanks are equivalent to a single blank, except in strings that have quotation marks (') round them., Commas are used as separators. Multiple commas are equivalent to a single comma, except in strings that have quotation marks (') round them. ' A single quotation mark indicates the beginning or end of a string. MQSeries leaves all characters that have quotation marks round them exactly as they are entered. The containing quotation marks are not included when calculating the length of the string. '' Two quotation marks together inside a string are treated by MQSeries as one quotation mark, and the string is not terminated. The double quotation marks are treated as one character when calculating the length of the string. ( An open parenthesis indicates the beginning of a parameter list. ) A close parenthesis indicates the end of a parameter list. : A colon indicates an inclusive range. For example (1:5) means (1,2,3,4,5). This notation can be used only in TRACE commands. * An asterisk means all. For example, DISPLAY TRACE (*) means display all traces, and DISPLAY QUEUE (PAY*) means display all queues whose names begin with PAY. When you need to use any of these special characters in a field (for example as part of a description), you must enclose the whole string in single quotation marks. Building command scripts You may want to build the MQSeries commands into a script when you use: v The CSQINP1, CSQINP2, and CSQINPX initialization data sets or the CSQUTIL batch utility on OS/390 2 MQSeries MQSC Command Reference

15 v The STRMQMMQSC command on OS/400 v The runmqsc command on Compaq (DIGITAL) OpenVMS, OS/2 Warp, Tandem NSK, UNIX systems, and Windows NT When you do this, follow these rules: v Each command must start on a new line. v On each platform, there might be platform-specific rules about the line length and record format. If scripts are to be readily portable to different platforms, the significant length of each line should be restricted to 72 characters. On OS/390, scripts are held in a fixed-format data set, with a record length of 80. Only columns 1 through 72 can contain meaningful information; columns 73 through 80 are ignored. On AIX, HP-UX, OS/2 Warp, OS/400, Sun Solaris, and Windows NT, each line can be of any length up to the maximum allowed for your platform. On other UNIX systems, and Compaq (DIGITAL) OpenVMS, each line can be of any length up to and including 80 characters. On Tandem NSK each line can be of any length up to and including 72 characters. v A line must not end in a keyboard control character (for example, a tab). v If the last nonblank character on a line is: A minus sign ( ), this indicates that the command is to be continued from the start of the next line. A plus sign (+), this indicates that the command is to be continued from the first nonblank character in the next line. If you use + to continue a command remember to leave at least one blank before the next parameter (except on OS/390 where this is not necessary). Either of these can occur within a parameter, data value, or quoted string. For example, 'Fr+ ed' and 'Fred' Rules for using commands (where the e of the second line of the second example is in the first position of the line) are both equivalent to 'Fred' v v MQSC commands that are contained within an Escape PCF (Programmable Command Format) command cannot be continued in this way. The entire command must be contained within a single Escape command. (For information about the PCF commands, see the MQSeries Programmable System Management manual.) + and values used at the ends of lines are discarded when the command is reassembled into a single string. On AIX, HP-UX, OS/2 Warp, OS/400, Sun Solaris, and Windows NT you can use a semicolon character (;) to terminate a command, even if you have entered a + character at the end of the previous line. You can also use the semicolon in the same way on OS/390 for commands issued from the CSQUTIL batch utility program. Chapter 1. Using MQSeries commands 3

16 Rules for using commands v A line starting with an asterisk (*) in the first position is ignored. This can be used to insert comments into the file. A blank line is also ignored. If a line ends with a continuation character ( or +), the command continues with the next line that is not a comment line or a blank line. Rules for naming MQSeries objects MQSeries queue, process, namelist, channel, and storage class objects exist in separate object name spaces, and so objects from each type can all have the same name. However, an object cannot have the same name as any other object in the same name space. (For example, a local queue cannot have the same name as a model queue.) Names in MQSeries are case sensitive; however, you should remember that lowercase characters that are not contained within quotation marks are folded to uppercase. The character set that can be used for naming all MQSeries objects is as follows: v Uppercase A Z v Lowercase a z (however, on systems using EBCDIC Katakana you cannot use lowercase characters, and there are also restrictions on the use of lowercase letters for OS/390 console support) v Numerics 0 9 v Period (.) v Forward slash (/) v Underscore (_) v Percent sign (%). The percent sign (%) is a special character to RACF. If you are using RACF as the external security manager for MQSeries for OS/390, you should not use % in object names. If you do, these names are not included in any security checks when RACF generic profiles are used. Notes: 1. Leading or embedded blanks are not allowed. 2. You should avoid using names with leading or trailing underscores, because they cannot be handled by the MQSeries for OS/390 operations and control panels. 3. Any name that is less than the full field length can be padded to the right with blanks. All short names that are returned by the queue manager are always padded to the right with blanks. 4. Any structure to the names (for example, the use of the period or underscore) is not significant to the queue manager. 5. When using CL commands or menus on AS/400 systems, lowercase a-z, forward slash (/), and percent (%) are special characters. If you use any of these characters in a name, the name must be enclosed in quotation marks. Lowercase a-z characters are changed to uppercase if the name is not enclosed in quotation marks. Queue names Queues can have names up to 48 characters long. 4 MQSeries MQSC Command Reference

17 Rules for naming objects Reserved queue names Names that start with SYSTEM. are reserved for queues defined by the queue manager.

19 How to read syntax diagrams This book contains syntax diagrams (sometimes referred to as railroad diagrams). Each syntax diagram begins with a double right arrow and ends with a right and left arrow pair. Lines beginning with a single right arrow are continuation lines. You read a syntax diagram from left to right and from top to bottom, following the direction of the arrows. Other conventions used in syntax diagrams are: Table 1. How to read syntax diagrams Convention Meaning A B C Syntax diagrams You must specify values A, B, and C. Required values are shown on the main line of a syntax diagram. A You may specify value A. Optional values are shown below the main line of a syntax diagram. A B C Values A, B, and C are alternatives, one of which you must specify. A B C Values A, B, and C are alternatives, one of which you may specify., A B C You may specify one or more of the values A, B, and C. Any required separator for multiple or repeated values (in this example, the comma (,)) is shown on the arrow. Chapter 1. Using MQSeries commands 7

20 Syntax diagrams Table 1. How to read syntax diagrams (continued) Convention Meaning, You may specify value A multiple times. The separator in this example is optional. A A B C Values A, B, and C are alternatives, one of which you may specify. If you specify none of the values shown, the default A (the value shown above the main line) is used. Name The syntax fragment Name is shown separately from the main syntax diagram. Name: A B Punctuation and uppercase values Lowercase values (for example, name) Specify exactly as shown. Supply your own text in place of the name variable. 8 MQSeries MQSC Command Reference

44 ALTER QMGR Queue manager parameters AUTHOREV Whether authorization (Not Authorized) events are generated: ENABLED Authorization events are generated. This value is not supported on OS/390. DISABLED Authorization events are not generated. This is the queue manager s initial default value. CCSID(integer) The coded character set identifier for the queue manager. The CCSID is the identifier used with all character string fields defined by the API. It does not apply to application data carried in the text of messages unless the CCSID in the message descriptor is set to the value MQCCSI_Q_MGR when the message is put to a queue. Specify a value in the range 1 through The CCSID must specify a value that is defined for use on your platform, and use a character set that is appropriate to the platform. If you use this parameter to change the CCSID, applications that are running when the change is applied continue to use the original CCSID. Because of this, you must stop and restart all running applications before you continue. This includes the command server and channel programs. To do this, stop and restart the queue manager after making the change. This parameter is valid only on AIX, HP-UX, OS/2 Warp, OS/400, Sun Solaris, Tandem NSK, and Windows NT. See the MQSeries Application Programming Guide for details of the supported CCSIDs for each platform. CHAD Whether receiver and server-connection channels can be defined automatically: DISABLED Auto-definition is not used. This is the queue manager s initial default value. ENABLED Auto-definition is used. Cluster-sender channels can always be defined automatically, regardless of the setting of this parameter. This parameter is valid only on AIX, HP-UX, OS/2 Warp, OS/400, Sun Solaris, and Windows NT. CHADEV Whether channel auto-definition events are generated. DISABLED Auto-definition events are not generated. This is the queue manager s initial default value. ENABLED Auto-definition events are generated. 32 MQSeries MQSC Command Reference

45 This parameter is valid only on AIX, HP-UX, OS/2 Warp, OS/400, Sun Solaris, and Windows NT. CHADEXIT(string) Auto-definition exit name. If this name is nonblank, the exit is called when an inbound request for an undefined receiver, server-connection, or cluster-sender channel is received. It is also called when starting a cluster-receiver channel. The format and maximum length of the name depends on the environment: v v On OS/2 Warp, Windows, and Windows NT, it is of the form dllname(functionname) where dllname is specified without the suffix (.DLL ). The maximum length of the string is 128 characters.
