Starting, Stopping, and Updating Your OSI/MHS
Subsystem

Summary
You run the installation procedures as described in Section 4, Installing Your OSI/MHS
Subsystem. The installation procedures compare the objects, check to see which
objects have changed, and update those objects.
Depending on your configuration, you might need to redefine objects or take other
steps to complete the upgrade. See Upgrading From an Earlier RVU on page 4-22 for
more information.
Unless noted specifically in Section 4, Installing Your OSI/MHS Subsystem. you need
not purge any existing files. The installation procedures take care of the updating. The
PDU stores, the configuration databases, and the SQL catalogs and tables usually
remain the same between updates.
Summary
To start an OSI/MHS subsystem, you perform the following steps:
1. If you use external password servers for adjacent MTAs or MS groups, define and
start the servers.
2. Specify startup parameters and run the MHS manager process.
3. Define all the MHS objects to the MHS manager.
4. Start the subsystem objects.
5. If you have gateway interfaces, define and start the wait and entry managers
before starting the GI groups.
You can run the MHS manager process by specifying parameters in the PARAM
command or by specifying all the parameters on the RUN command line. You define
all the objects to the MHS manager by using an SCF command file. Examples of
command files are included in Appendix A, Examples of Configuration Files.
You use the START command to start the subsystem objects, and you must specify
them in a particular order. Likewise, when you shut down the subsystem, you use the
STOP command and specify the objects in the reverse order.
When you restart the subsystem, you do not need to redefine the objects because they
already exist.
To update the software, follow the directions in the softdocs, do an orderly shutdown,
and then reinstall the subsystem using the installation procedure. Then follow the
steps to start the subsystem.
Section 7, Managing Your OSI/MHS Subsystem, describes the tasks you perform on a
more regular basis to manage the OSI/MHS subsystem.
