●     Archiving of messages processed successfully
●     Deletion of messages that are not to be archived
●     Restarting of messages with errors
●     Rescheduling of lost messages

Answer 1

Background Processing
Prerequisites
You have started the message monitor on the initial screen of the PCK and are in Background Processing.
Features
Archiving
You require two archiving sessions to archive messages:
●     One session to write the messages to the archive
●     One session to delete the persisted messages that have been archived
To do this, you schedule an archiving job, which implicitly schedules the sessions to write to the archive and delete the archived messages.
You can define one or more rules for each archiving job; these rules contain conditions that a message must meet in order to be archived by the job. At least one of the defined rules must be met for archiving to take place.
All information that is displayed for a message in message monitoring is archived, in addition to the audit log for each message.
Deleting
A standard delete job is created automatically. It runs once a day. You can schedule additional delete jobs; however, you cannot define rules for them.
Restarting
Instead of restarting messages with errors manually with message monitoring, you can schedule a job to automatically restart these messages. This is possible for all messages for which the number of defined restart attempts has been exceeded (messages with the system error status).
You can define one or more rules for each job to restart messages; these rules contain conditions that a message must meet in order to be restarted by the job. At least one of the defined rules must be met for archiving to take place.
Rescheduling
A standard job to reschedule messages is created automatically. The job runs once a day and ensures that messages lost as a result of database failure, for example, are rescheduled. You can schedule additional rescheduling jobs; however, you cannot define rules for them.
Thx Aamir.
But I mean the messages with errors in Adapter Engine , not in Intergrations Engine.
the situation is like Naveen Pandrangi's WebLog
II. Errors in Adapter Engine [XI :  How to Re-Process failed XI Messages Automatically|XI :  How to Re-Process failed XI Messages Automatically]
I
Till now we have seen how to resubmit/restart message that failed in Integration Engine.  One a message makes it from Integration Engine to Adapter Engine, the message is flagged as checked in Integration Engine. The status of the message in Adapter engine does not effect the processed state in Integration Engine. Now if this message was asynchronous, XI will by default try to restart the message 3 times at intervals of 5 minutes before the status of the message is changed from Waiting to System Error .
*how can i schedule a job to automatically restart these messages with errors?
best regards
