APPL Objects
The STARTED state for an OSI/MHS user application means it can be used to validate
and allow a request from its UA or gateway to establish an association to the
subsystem and to submit or retrieve messages. The STARTED state results from
directing:
•
A START command to an APPL object that is in the STOPPED state
•
An ACTIVATE command to an APPL object that is in the SUSPENDED state
The STOPPED state, for an OSI/MHS user application, means:
•
OSI/MHS does not accept any requests from its UA or gateway.
•
Incoming messages for its UA or gateway are rejected with a nondelivery report.
An APPL object must be in the STOPPED state before you can alter its attributes.
An APPL object cannot be started while the RESTMBOX utility is running. The APPL
will be started when RESTMBOX has completed its processing. (See Appendix C,
Mailbox Save and Restore Utilities, for descriptions of the mailbox save and restore
utilities.)
You stop an APPL object by directing an ABORT or STOP command to it. (The effect
of a STOP NORMAL command could differ from the effect of a STOP FORCED or an
ABORT command.)
The SUSPENDED state, for an OSI/MHS user application, means that the application
allows some requests from its UA and not others. Suspending an application before
deleting it is useful because it allows you to empty the mailbox.
When an APPL object for a UA is suspended and the UA tries to establish an
association, the subsystem allows this, but it notifies the UA that it is subject to controls
on submit requests. The subsystem accepts the requests from the UA to list, retrieve,
and delete messages already in the MS PDU store. However, the subsystem will
