# ohparam(1)

An openhpi sample application that uses the openhpi additional interface to control openhpi configuration parameters

## NAME

ohparam - An openhpi sample application that uses the openhpi additional interface to control openhpi configuration parameters

## SYNOPSIS

```
 ohparam [-D nn] [-N host[:port]] [-C <cfgfile>] [-X] get
 ohparam [-D nn] [-N host[:port]] [-C <cfgfile>] [-X] set <paramname newvalue>
 ohparam [--domain nn] [--host=host[:port]] [--cfgfile=file] [--debug] get
 ohparam [--domain nn] [--host=host[:port]] [--cfgfile=file] [--debug] set <paramname newvalue>
```

## DESCRIPTION

ohparam get will display all global configuration parameters of the openhpi daemon for the specified domain.

ohparam set will change the given global configuration parameters of the openhpi daemon for the specified domain to the new value.

If no domain or host is selected, ohparam uses the default domain as specified in the openhpiclient.conf file.

## COMMANDS

```
 Command get: display info about all global parameters
         no specific arguments
 Command set:
         one of the daemon's global parameters:
         (without the OPENHPI prefix)
           LOG_ON_SEV, EVT_QUEUE_LIMIT,
           DEL_SIZE_LIMIT, DEL_SAVE
           DAT_SIZE_LIMIT, DAT_USER_LIMIT, DAT_SAVE
           PATH, VARPATH, CONF
         and the desired new value. Example:
           ohparam set DEL_SIZE_LIMIT 20000
```

## OPTIONS

### Help Options:

- **-h**, **--help**

  Show help options

### Application Options:

- **-D** *nn*, **--domain**=*nn*

  Select domain id *nn*

- **-X**, **--debug**

  Display debug messages

- **-N** *"host\[:port\]"*, **--host**=*"host\[:port\]"*

  Open session to the domain served by the daemon at the specified URL (host:port). This option overrides the OPENHPI\_DAEMON\_HOST and OPENHPI\_DAEMON\_PORT environment variables. If host contains ':' (for example IPv6 address) then enclose it in square brackets. For example: *"\[::1\]"* or *"\[::1\]:4743"*.

- **-C** *"file"*, **--cfgfile**=*"file"*

  Use passed file as client configuration file. This option overrides the OPENHPICLIENT\_CONF environment variable.
