Parameter descriptions

You must specify a connection for which you want to display information. This can be a specific connection identifier or a generic connection identifier. A single asterisk (*) can be used as a generic connection identifier to display information for all connections.

(generic-connid)
The identifier of the connection definition for which information is to be displayed. A single asterisk (*) specifies that information for all connection identifiers is to be displayed.

When an application connects to WebSphere MQ, it is given a unique 24-byte connection identifier (ConnectionId). The value for CONN is formed by converting the last eight bytes of the ConnectionId to its 16-character hexadecimal equivalent.

WHERE
Specify a filter condition to display only those connections that satisfy the selection criterion of the filter condition. The filter condition is in three parts: filter-keyword, operator, and filter-value:
filter-keyword
Almost any parameter that can be used to display attributes for this DISPLAY command. However, you cannot use the CMDSCOPE, EXTCONN, QSGDISP, TYPE, and EXTURID parameters as filter keywords.
operator
This is used to determine whether a connection satisfies the filter value on the given filter keyword. The operators are:
LT
Less than
GT
Greater than
EQ
Equal to
NE
Not equal to
LE
Less than or equal to
GE
Greater than or equal to
LK
Matches a generic string that you provide as a filter-value
NL
Does not match a generic string that you provide as a filter-value
CT
Contains a specified item. If the filter-keyword is a list, you can use this to display objects the attributes of which contain the specified item. You cannot use the CONNOPTS value MQCNO_STANDARD_BINDING with this operator.
EX
Does not contain a specified item. If the filter-keyword is a list, you can use this to display objects the attributes of which do not contain the specified item. You cannot use the CONNOPTS value MQCNO_STANDARD_BINDING with this operator.
filter-value
The value that the attribute value must be tested against using the operator. Depending on the filter-keyword, this can be:
  • An explicit value, that is a valid value for the attribute being tested.

    You can use operators LT, GT, EQ, NE, LE or GE only. However, if the attribute value is one from a possible set of values on a parameter (for example, the value NONE on the UOWSTATE parameter), you can only use EQ or NE.

  • A generic value. This is a character string (such as the character string in the APPLTAG parameter) with an asterisk at the end, for example ABC*. If the operator is LK, all items where the attribute value begins with the string (ABC in the example) are listed. If the operator is NL, all items where the attribute value does not begin with the string are listed.

    You cannot use a generic filter-value for parameters with numeric values or with one of a set of values.

  • An item in a list of values. Use CT or EX as the operator. For example, if the value DEF is specified with the operator CT, all items where one of the attribute values is DEF are listed.
ALL
Specify this to display all the connection information of the requested type for each specified connection. This is the default if you do not specify a generic identifier, and do not request any specific parameters.
CMDSCOPE
This parameter applies to z/OS only and specifies how the command is executed when the queue manager is a member of a queue-sharing group.

' '
The command is executed on the queue manager on which it was entered. This is the default value.
qmgr-name
The command is executed on the queue manager you specify, providing the queue manager is active within the queue-sharing group.

You can specify a queue manager name, other than the queue manager on which it was entered, only if you are using a queue-sharing group environment and if the command server is enabled.

*
The command is executed on the local queue manager and is also passed to every active queue manager in the queue-sharing group. The effect of this is the same as entering the command on every queue manager in the queue-sharing group.

You cannot use CMDSCOPE as a filter keyword.

EXTCONN
The value for EXTCONN is based on the first sixteen bytes of the ConnectionId converted to its 32-character hexadecimal equivalent.

Connections are identified by a 24-byte connection identifier. The connection identifier comprises a prefix, which identifies the queue manager, and a suffix which identifies the connection to that queue manager. By default, the prefix is for the queue manager currently being administered, but you can specify a prefix explicitly by using the EXTCONN parameter. Use the CONN parameter to specify the suffix.

When connection identifiers are obtained from other sources, specify the fully qualified connection identifier (both EXTCONN and CONN) to avoid possible problems related to non-unique CONN values.

Do not specify both a generic value for CONN and a non-generic value for EXTCONN.

You cannot use EXTCONN as a filter keyword.

TYPE
Specifies the type of information to be displayed. Values are:
CONN
Connection information for the specified connection. On z/OS, this includes threads which may be logically or actually disassociated from a connection, together with those that are in-doubt and for which external intervention is needed to resolve them. These latter threads are those that DIS THREAD TYPE(INDOUBT) would show.
HANDLE
Information relating to any objects opened by the specified connection.
*
Display all available information relating to the connection.
ALL
Display all available information relating to the connection.

Conn attrs

If TYPE is set to CONN, the following information is always returned for each connection that satisfies the selection criteria, except where indicated:

The following parameters can be specified for TYPE(CONN) to request additional information for each connection. If a parameter is specified that is not relevant for the connection, operating environment, or type of information requested, that parameter is ignored.

APPLTAG

A 4-character address-space identifier of the application identified by APPLTAG. It distinguishes duplicate values of APPLTAG.

This parameter is returned only on z/OS when the APPLTYPE parameter does not have the value SYSTEM.

This parameter is valid only on z/OS.

CHANNEL
The name of the channel that owns the connection. If there is no channel associated with the connection, this parameter is blank.
CONNAME
The connection name associated with the channel that owns the connection. If there is no channel associated with the connection, this parameter is blank.
CONNOPTS
The connect options currently in force for this application connection. Possible values are:

You cannot use the value MQCNO_STANDARD_BINDING as a filter value with the CT and EX operators on the WHERE parameter.

EXTURID
The external unit of recovery identifier associated with this connection. Its format is determined by the value of URTYPE.

You cannot use EXTURID as a filter keyword.

NID
Origin identifier, set only if the value of UOWSTATE is UNRESOLVED. This is a unique token identifying the unit of work within the queue manager. It is of the form origin-name.origin-urid where

This parameter is valid only on z/OS.

PID
Number specifying the process identifier of the application that is connected to the queue manager.

This parameter is not valid on Compaq NSK and z/OS.

PSBNAME
The 8-character name of the program specification block (PSB) associated with the running IMS transaction. You can use the PSBNAME and PSTID to purge the transaction using IMS commands. It is valid on z/OS only.

This parameter is returned only when the APPLTYPE parameter has the value IMS.

PSTID
The 4-character IMS program specification table (PST) region identifier for the connected IMS region. It is valid on z/OS only.

This parameter is returned only when the APPLTYPE parameter has the value IMS.

QMURID
The queue manager unit of recovery identifier. On z/OS, this is a 6-byte log RBA, displayed as 12 hexadecimal characters. On platforms other than z/OS, this is an 8-byte transaction identifier, displayed as m.n where m and n are the decimal representation of the first and last 4 bytes of the transaction identifier.

You can use QMURID as a filter keyword. On z/OS, you must specify the filter value as a hexadecimal string. On platforms other than z/OS, you must specify the filter value as a pair of decimal numbers separated by a period (.). You can only use the EQ, NE, GT, LT, GE, or LE filter operators.

TASKNO
A 7-digit CICS task number. This number can be used in the CICS command "CEMT SET TASK(taskno) PURGE" to end the CICS task. This parameter is valid on z/OS only.

This parameter is returned only when the APPLTYPE parameter has the value CICS.

TID
Number specifying the thread identifier within the application process that has opened the specified queue.

This parameter is not valid on z/OS.

TRANSID
A 4-character CICS transaction identifier. This parameter is valid on z/OS only.

This parameter is returned only when the APPLTYPE parameter has the value CICS.

UOWLOG

The state of the unit of work. It is one of the following:
NONE
There is no unit of work.
ACTIVE
The unit of work is active.
PREPARED
The unit of work is in the process of being committed.
UNRESOLVED
The unit of work is in the second phase of a two-phase commit operation. WebSphere MQ holds resources on its behalf and external intervention is required to resolve it. This might be as simple as starting the recovery coordinator (such as CICS, IMS, or RRS) or it might involve a more complex operation such as using the RESOLVE INDOUBT command. The UNRESOLVED value can occur only on z/OS.
UOWSTDA
The date that the transaction associated with the current connection was started.
UOWSTTI
The time that the transaction associated with the current connection was started.
URTYPE
The type of unit of recovery as seen by the queue manager. It is one of the following:

URTYPE identifies the EXTURID type and not the type of the transaction coordinator. When URTYPE is QMGR, the associated identifier is in QMURID (and not EXTURID).

USERID
The user identifier associated with the connection.

This parameter is not returned when APPLTYPE has the value SYSTEM.

Handle attrs

If TYPE is set to HANDLE, the following information is always returned for each connection that satisfies the selection criteria, except where indicated:

The following parameters can be specified for TYPE(HANDLE) to request additional information for each queue. If a parameter is specified that is not relevant for the connection, operating environment, or type of status information requested, that parameter is ignored.

HSTATE
The state of the handle.

Possible values are:

ACTIVE
An API call from this connection is currently in progress for this object. If the object is a queue, this condition can arise when an MQGET WAIT call is in progress.

If there is an MQGET SIGNAL outstanding, then this does not mean, by itself, that the handle is active.

INACTIVE
No API call from this connection is currently in progress for this object. If the object is a queue, this condition can arise when no MQGET WAIT call is in progress.
OBJNAME
The name of an object that the connection has open.

Indicates the disposition of the object. It is valid on z/OS only. The value is one of the following:
QMGR
The object was defined with QSGDISP(QMGR).
COPY
The object was defined with QSGDISP(COPY).
SHARED
The object was defined with QSGDISP(SHARED).

You cannot use QSGDISP as a filter keyword.

Full attrs

If TYPE is set to *, or ALL, both Conn attributes and Handle attributes are returned for each connection that satisfies the selection criteria.

Usage notes

This command is issued internally by WebSphere MQ on z/OS when taking a checkpoint, and when the queue manager is starting and stopping, so that a list of units of work that are in doubt at the time is written to the z/OS console log.
