Alternative MPS Configurations
An MPS process can have a maximum of 16 openers at a time, including all MS
processes and the MHSMGR. No process can have multiple concurrent opens of an
MPS process.
Load Sharing Configuration
In Figure 7-4, two MPS processes share the load of authorization of APPL Bind and
Register-MS operations (and ADD, ALTER and DELETE APPL requests) for all the
MS groups. There is one configuration database (one master user), and there is one
authorization database for each MPS process. Each MPS process uses a separate
spooler file for its audit-trail; if the audit-trail file were a terminal or disk file, the MPS
processes would share it.
In this example, MS2 is configured to use MPS1; MS1, MS2, and MS4 are configured
to use MPS2. The MHSMGR automatically uses whichever MPS is appropriate,
depending on the APPL. You use the SCF ALTER GROUP command to specify which
MPS process serves each MS group.
This configuration can provide a faster response time than the single-process
configuration because there are two MPS processes at work simultaneously, each
serving different users.
