Interface AuditAccess

public interface AuditAccess

The AuditAccess interface offers methods to write an AuditLogEntry to the memory audit store with the given status. For performance reasons all AuditLogEntry objects, created with this method will by default be kept in the memory audit store, till they are explicitly flushed to the DB for a specific MessageKey.
This will usually be done automatically by the Messaging System, whenever a message reached a final state (i.e. DELIVERED, NOT DELIVERED, FAILED). AuditLogEntry objects are merged together from the memory audit store and the BC_MSG_AUDIT DB table (and sorted), before they are getting returned to the UI for displaying purpose, through the method getAuditEntryList(PublicMessageKey msgKey) of the AuditLogManager class. There are several auditSuccess, auditWarning and auditError method signatures, which allow to ommit the PublicMesageKey, if not known and the parameters for the text key, if available.

If third party Adapter developers want to use the offered AuditLog capabilities, they are required to create a MessageKey (consisting of a GUID messageId and a MessageDirection object) as early as possible and to pass that MessageKey to the AdapterFramework, as part of the Message representation.
Since flushing the AuditLogEntries for a specific MessageKey causes DB access and therefore is a performance issue, it's up the application developers, when and how often they need to call the flush method additionally, to avoid loosing audit entries (especially in case of errors on sending side)..

Method Detail

addAuditLogEntry

void addAuditLogEntry(MessageKey msgKey,
                      AuditLogStatus status,
                      String textKey,
                      Object[] params)

Writes an AuditLogEntry to the memory audit store with the given status.

Parameters:

msgKey - The MessageKey, for which the AuditLogEntry is to be written.

textKey - The key of the message text in the ResourceBundle used in the AuditLog UI JSP page. For 3rd party application/adapter development it's also possible to pass in an already localized text String, instead of a resource bundle key. In this case it is also possible to use the Java TextFormatter's placeholder concept and the additional params ({0}...{x}).

params - Some (up to AditLogEntry.MAX_PARAMS) additional params for the message text

status - AuditLogStatus

addAuditLogEntry

void addAuditLogEntry(MessageKey msgKey,
                      AuditLogStatus status,
                      String textKey)

flushAuditLogEntries

void flushAuditLogEntries(MessageKey msgKey)

This method is used to explicitly flush all AuditLogEntry objects stored in the memory audit store for a given MessagKey to the BC_MSG_AUDIT DB table. For performance improvements, all added AuditLogEntry objects are by default kept in the memory audit store, till they get explicitly flushed to the DB. The flushing is to be done, when the message reached a final state (i.e. DELIVERED, NOT DELIVERED, FAILED) and when the message processing flow leaves the AdapterFramework. The MS automatically flushs at central points, and it is up to the appliations, how often they want to flush additionally, to avoid loosing audit entries (especially in case of errors on sending side).

Parameters:

msgKey - The MessageKey of the message to be flushed to the DB.
