MQZ_REFRESH_CACHE - Refresh all authorizations

This function is provided by an MQZAS_VERSION_3 authorization service component, and is invoked by the queue manager to refresh the list of authorizations held internally by the component.

The function identifier for this function (for MQZEP) is MQZID_REFRESH_CACHE (8L).

 

Syntax

MQZ_REFRESH_CACHE

(QMgrName, ComponentData, Continuation, CompCode, Reason)

 

Parameters

QMgrName (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 make use of it in any defined manner.

ComponentData (MQBYTE×ComponentDataLength) -- 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 this component's 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 (MQLONG) -- output

Continuation indicator set by component.

The following values can be specified:

MQZCI_DEFAULT

Continuation dependent on queue manager.

For MQZ_REFRESH_CACHE this has the same effect as MQZCI_CONTINUE.

MQZCI_CONTINUE

Continue with next component.

MQZCI_STOP

Do not continue with next component.

CompCode (MQLONG) -- output

Completion code.

It is one of the following:

MQCC_OK

Successful completion.

MQCC_FAILED

Call failed.

Reason (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_SERVICE_ERROR

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

For more information on this reason code, see the WebSphere MQ Application Programming Reference book.

 

C invocation

MQZ_REFRESH_CACHE (QMgrName, ComponentData,
                   &Continuation, &CompCode, &Reason);

Declare the parameters as follows:

MQCHAR48  QMgrName;          /* Queue manager name */
MQBYTE    ComponentData[n];  /* Component data */
MQLONG    Continuation;      /* Continuation indicator set by
                                component */
MQLONG    CompCode;          /* Completion code */
MQLONG    Reason;            /* Reason code qualifying CompCode */
