MQZ_SET_AUTHORITY - Set authority

This function is provided by a MQZAS_VERSION_1 authorization service component, and is started by the queue manager to set the authority that an entity has to access the specified object.

The function identifier for this function (for MQZEP) is MQZID_SET_AUTHORITY.

Note: This function overrides any existing authorities. To preserve any existing authorities we must set them again with this function.

Syntax

MQZ_SET_AUTHORITY( QMgrName , EntityName , EntityType , ObjectName , ObjectType , Authority , ComponentData , Continuation , CompCode , Reason )

Parameters

QMgrName

Type: MQCHAR48 - input

Queue manager name. The name of the queue manager calling the component. This name is padded with blanks to the full length of the parameter; the name is not terminated by a null character.

The queue manager name is passed to the component for information; the authorization service interface does not require the component to use it in any defined manner.

EntityName

Type: MQCHAR12 - input

Entity name. The name of the entity for which access to the object is to be retrieved. The maximum length of the string is 12 characters; if it is shorter than that it is padded to the right with blanks. The name is not terminated by a null character.

EntityType

Type: MQLONG - input Entity type. The type of entity specified by EntityName. It must be one of the following values:

MQZAET_PRINCIPAL

Principal.

MQZAET_GROUP

Group.

ObjectName

Type: MQCHAR48 - input

Object name. The name of the object to which access is required. The maximum length of the string is 48 characters; if it is shorter than that it is padded to the right with blanks. The name is not terminated by a null character.

If ObjectType is MQOT_Q_MGR, this name is the same as QMgrName.

ObjectType

Type: MQLONG - input Object type. The type of entity specified by ObjectName. It must be one of the following values:

MQOT_AUTH_INFO

Authentication information.

MQOT_CHANNEL

Channel.

MQOT_CLNTCONN_CHANNEL

Client connection channel.

MQOT_LISTENER

Listener.

MQOT_NAMELIST

Namelist.

MQOT_PROCESS

Process definition.

MQOT_Q

Queue.

MQOT_Q_MGR

Queue manager.

MQOT_SERVICE

Service.

MQOT_TOPIC

Topic.

Authority

Type: MQLONG - input

Authority of entity. If one authority is being set, this field is equal to the appropriate authorization operation (MQZAO_* constant). If more than one authority is being set, this field is the bitwise OR of the corresponding MQZAO_* constants.

ComponentDatarname>

Type: MQBYTExComponentDataLength - input/output

Component data. This data is kept by the queue manager on behalf of this particular component; any changes made to it by any of the functions provided by this component are preserved, and presented the next time one of these component functions is called.

The length of this data area is passed by the queue manager in the ComponentDataLength parameter of the MQZ_INIT_AUTHORITY call.

Continuation

Type: MQLONG - output Continuation indicator set by component. The following values can be specified:

MQZCI_DEFAULT

Continuation dependent on queue manager.

For MQZ_GET_AUTHORITY, this has the same effect as MQZCI_CONTINUE.

MQZCI_CONTINUE

Continue with next component.

MQZCI_STOP

Do not continue with next component.

CompCode

Type: MQLONG - output Completion code. It must be one of the following values:

MQCC_OK

Successful completion.

MQCC_FAILED

Call failed.

Reason

Type: MQLONG - output

Reason code qualifying CompCode.

If CompCode is MQCC_OK:

MQRC_NONE

(0, X'000') No reason to report.

If CompCode is MQCC_FAILED:

MQRC_NOT_AUTHORIZED

(2035, X'7F3') Not authorized for access.

MQRC_SERVICE_ERROR

(2289, X'8F1') Unexpected error occurred accessing service.

MQRC_SERVICE_NOT_AVAILABLE

(2285, X'8ED') Underlying service not available.

MQRC_UNKNOWN_ENTITY

(2292, X'8F4') Entity unknown to service.

For more information about these reason codes, see API reason codes.

C invocation

MQZ_SET_AUTHORITY (QMgrName, EntityName, EntityType, ObjectName,
                  ObjectType, Authority, ComponentData,
                  &Continuation, &CompCode, &Reason);

The parameters passed to the service are declared as follows:

MQCHAR48  QMgrName;          /* Queue manager name */
MQCHAR12  EntityName;        /* Entity name */
MQLONG    EntityType;        /* Entity type */
MQCHAR48  ObjectName;        /* Object name */
MQLONG    ObjectType;        /* Object type */
MQLONG    Authority;         /* Authority to be checked */
MQBYTE    ComponentData[n];  /* Component data */
MQLONG    Continuation;      /* Continuation indicator set by
                                component */
MQLONG    CompCode;          /* Completion code */
MQLONG    Reason;            /* Reason code qualifying CompCode */
