NAMEopenhpid − HPI instance to which multiple clients can connect.
SYNOPSISopenhpid −c config_file [OPTION]
DESCRIPTIONThe OpenHPI daemon runs as a background process and accepts connections from remote clients that invoke HPI function calls. The daemon wraps the OpenHPI library with a sockets-based API that is archicture neutral for all types of clients. When you run the daemon, the standard method for locating the OpenHPI configuration file is used. However, the daemon will accept a configuration file as a command line option (−c) to override the default file. A command option (−p) or environment variable determines the port number the daemon will listen on for client connections. The default port is 4743. The daemon creates a PID file in the /var/run subdirectory. This directory is only writable by the root user. Thus the daemon will fail when run as a normal user if the PID file location is not overridden. To override the PID file location you can use the −f command line option. The client and the daemon do not have to be on the same hardware architecture. The daemon could be running on a P−series processor and the client running on an x86−series processor. The client library and daemon use a marshaling technique to resolve architecture and structure padding conflicts. The user does not need to concern themselves with architectureal differences between the client and daemon. The one exception to this rule is 64−bit architectures. The client and daemon currently cannot resolve differences between 32−bit and 64−bit architectures.
OPTIONS−f pidfile This overrides the default location of the pidfile. −n This forces the daemon to run in the foreground. −p port This is used to override the port to listen on by the daemon. −s seconds Read timeout used by the daemon sockets. Default is unlimited. −t threads Sets the maximum number of connection threads. Default is unlimited. −v Display verbose messages
ENVIRONMENTAL VARIABLESAll of these environment variables can instead be set in the openhpi.conf configuration file, except for OPENHPI_DAEMON_PORT and OPENHPI_CONF. OPENHPI_DAEMON_PORT=PORT_NUMBER The port number the host will listen on for clent connections. Default port is 4743. OPENHPI_LOG_ON_SEV Valus can be one of: CRITICAL,MAJOR,MINOR,INFORMATIONAL,OK,DEBUG. Events of this severity or higher will be logged to the domain event log. The default is MINOR. OPENHPI_ON_EP=ENTITY_PATH Entity path returned (e.g. {SYSTEM_CHASSIS,1}) when saHpiResourceIdGet() is called. OPENHPI_EVT_QUEUE_LIMIT=NUMBER Maximum number of events allowed in a subscribed session's queue. Default is 10000. OPENHPI_DEL_SIZE_LIMIT=NUMBER Maximum number of events allowed in the domain event log. Default is 10000 OPENHPI_DEL_SAVE Set to YES to persist the domain event logs to disk. They will be loaded in case the daemon restarts. Default is NO. OPENHPI_DAT_SIZE_LIMIT=NUMBER Maximum number of alarms allowed in the domain alarm table. Default is unlimited. OPENHPI_DAT_USER_LIMIT=NUMBER Maximum number of user alarms allowed in the domain alarm table. Default is unlimited. OPENHPI_DAT_SAVE Set to YES to persist the domain alarm tables to disk. They will be loaded in case the daemon restarts. Default is NO. OPENHPI_PATH=``/path/to/plugins:/another/path/to/plugins'' This is a colon delimited list of directories used when searching for an OpenHPI plugin to load. The default is $prefix/lib/openhpi. OPENHPI_VARPATH=``/path/to/dir'' This sets the directory used to store openhpi internal data. The domain event logs and alarm tables are saved there (if configured to) along with resource ID to entity path mappings. Default is $prefix/var/lib/openhpi. OPENHPI_CONF=``/path/to/configurationg/file'' This is another way of telling the daemon where to find the configuration file.
