SQL Communication Subsystem
Management Interfaces
One of the NonStop ODBC Server requirements is to provide interfaces for managing
a potentially large and complex NonStop ODBC Server system (involving several
clients or heavy workloads from each client).
The NonStop ODBC Server does not provide additional functions for managing
NonStop SQL/MP objects and Pathway systems beyond those provided by these
products. The NonStop ODBC Server does provide a number of configuration
interfaces (described in later subsections) as well as some basic EMS and SCF
support within SCF so that an administrator can monitor a NonStop ODBC Server
system.
•
EMS interface–SCS generates EMS messages for session events (starting,
stopping) and NonStop ODBC server events (starting, started). An administrator
can scan the EMS log to diagnose problems.
•
SCF interface–SCS supports commands to show the status of all sessions and all
servers. The administrator can identify particular session and server attributes and
use other tools to probe further. For example, the name of a NonStop ODBC server
can be used to check process status or to stop the process.
