The Call Processing Trace shows that the message has been made unplayable for all mailboxes
using the M PURGE command.
■
MPURGE Usage
A message that has been recorded and sent can be deleted from one or all mailboxes in the
system.
From all mailboxes, the MPURGE first initiates an MBLOCK command so that, while the
system is searching each mailbox for an occurrence of the message, mailbox holders cannot
play that message.
The search that occurs after the MBLOCK command is issued can take some time to execute.
For example, on a system with 1,200 mailboxes, the search takes approximately 1/2 hour. Also,
seconds or even minutes may elapse between display of the next “mailbox scheduled for
deletion” prompt. When the search has completed,because the MBLOCK command is issued by
the system prior to beginning the message purge search, the message continues to utilize the
header assigned to it, and it remains on the disk until the system is restarted.
When the MPURGE command is issued to delete a message from an individual mailbox, the
MBLOCK command is not evoked. The message is deleted from the mailbox specified. When
issued for a particular mailbox, the MPURGE command is quick to execute. If a message was
sent, for example, to three mailboxes and purged one mailbox at a time from each of the three,
after the final deletion, the message is deleted from the disk and the header is made available
for reuse.
Whether for a single mailbox or for all mailboxes, when the MPURGE command is issued to
request that a message be deleted, if the mailbox holder is logged ON, the request to delete is
queued, and the deletion occurs after the mailbox holder logs OFF.
If the system is restarted while deletion requests are queued, those queued requests are lost.
However, the message remains unplayable if it has been blocked (explicitly by MBLOCK or
implicitly by the all-mailbox MPURGE command). To verify that messages have been deleted
before restarting the system, check the trace log.
