# mnesia\_session(3erl)

Mnesia\_Session

## NAME

mnesia\_session - Mnesia\_Session

## DESCRIPTION

Mnesia is written in Erlang and intended to be used for Erlang applications.

The Mnesia\_Session application enables access to the Mnesia DBMS from foreign programming languages (i.e. other languages than Erlang). The Mnesia\_Session interface is defined in IDL (an Interface Definition Language standardized by OMG (the Object Management Group)).

This module is automatically generated from the IDL specification *mnesia\_session.idl* and is documented in the IDL specification.

## Configuration parameters

Mnesia\_Session reads the following application configuration parameters:

- \*

  *-mnesia\_session corba\_connector\_name Name*. This parameter controls which initial name Mnesia Corba Connector is bound. This parameter is only used when the *enable\_corba* is set to true. The name is validated by using *lname:check\_name(Name)*. See the *Orber* application for details. The default name is *{'CosNaming\_NameComponent', "IDL:CosNaming/NameComponent:1.0", "mnesia\_corba\_connector", \[\]}*.

- \*

  *-mnesia\_session debug Level* Controls the debug level of Mnesia\_Session. Possible values are:

  - ***none*:**

    No trace outputs at all. This is the default.

  - ***verbose*:**

    Activates tracing of important debug events.

  - ***debug*:**

    Activates all events at the verbose level and traces of all debug events.

  - ***trace*:**

    Activates all debug events both verbose and debug as well as trace events that provide internal printouts. \
     This level is only intended for debugging of small toy systems since many large events may be generated.

- \*

  *-mnesia\_session enable\_corba true \| false*. This flag enables Mnesia\_Session to access Mnesia via CORBA. If CORBA access is enabled, the application Orber must be started in order to start Mnesia Session. The default is *false*.

First the SASL application parameters are checked, then the command line flags are checked, and finally, the default value is chosen.
