<modulesummary>The main module of the Orber application</modulesummary>
<description>
<p>This module contains the functions for starting and stopping the
application. It also has some utility functions to get some of
the configuration information from running application.</p>
</description>
<funcs>

<name>start(Type) -> ok</name>
<fsummary>Start the Orber application</fsummary>
<type>
<v>Type = temporary | permanent</v>
</type>
<desc>
<p>Starts the Orber application (it also starts mnesia if it is not running).
Which <c>Type</c> parameter is supplied determines the behavior. If not
supplied Orber is started as <c>temporary</c>.
See the Reference Manual <em>application(3)</em> for further information. </p>
</desc>
</func>
<func>
<name>jump_start(Attributes) -> ok | {'EXIT', Reason}</name>
<fsummary>Start the Orber application during tests</fsummary>
<type>
<v>Attributes = Port | Options</v>
<v>Port = integer()</v>
<v>Options = [{Key, Value}]</v>
<v>Key = any key listed in the configuration chapter</v>

</type>
<desc>
<p>Installs and starts the Orber and the Mnesia applications with the configuration
parameters <c>domain</c> and <c>iiop_port</c> set to <c>"IP-number:Port"</c>
and the supplied Port respectively. Theses settings are in most cases
sufficient to ensure that no clash with any other Orber instance occur.
If this operation fails, check if the listen port (iiop_port) is already
in use. This function <em>MAY ONLY</em> be used during development and
tests; how Orber is configured when using this operation may change
at any time without warning.</p>

see the user's guide.</p>
</desc>
</func>
<func>
<name>domain() -> string()</name>
<fsummary>Display the Orber domain name</fsummary>

<p>This function returns the domain name of the current Orber domain
as a string.</p>
</desc>
</func>
<func>
<name>iiop_port() -> int()</name>
<fsummary>Display the IIOP port number</fsummary>
<desc>
<p>This function returns the port-number, which is used by the IIOP
protocol. It can be configured by setting the application variable
<em>iiop_port</em>, if it is not set it will have the default number
4001.</p>
</desc>
</func>
<func>
<name>iiop_out_ports() -> 0 | {Min, Max}</name>
<fsummary>Display the ports Orber may use when connecting to another ORB</fsummary>
<desc>
<p>The return value of this operation is what the configuration
parameter <seealso marker="ch_install#config">iiop_out_ports</seealso>
has been set to.</p>
</desc>
</func>
<func>
<name>iiop_out_ports_random() -> true | false</name>

<fsummary>Display the IIOP port number used for secure connections</fsummary>
<desc>
<p>This function returns the port-number, which is used by the secure IIOP
protocol. It can be configured by setting the application variable
<em>iiop_ssl_port</em>, if it is not set it will have the default number
4002 if Orber is to configured to run in secure mode. Otherwise it returns -1.</p>
</desc>
</func>
<func>
<name>iiop_timeout() -> int() (milliseconds)</name>
<fsummary>Display the IIOP timeout value</fsummary>
<desc>
<p>This function returns the timeout value after which outgoing IIOP requests terminate.
It can be configured by setting the application variable
<em>iiop_timeout TimeVal (seconds)</em>, if it is not set it will have the default value
<em>infinity</em>. If a request times out a system exception, e.g.
<em>TIMEOUT</em>, is raised.</p>
<p>Note: the iiop_timeout configuration parameter (TimeVal) may only range between 0 and 1000000 seconds.
Otherwise, the default value is used.</p>
<p>Note: Earlier IC versions required that the compile option <c>{timeout,"module::interface"}</c>,
was used, which allow the user to add an extra timeout parameter, e.g.,
<c>module_interface:function(ObjRef, Timeout, ... Arguments ...)</c> or
<c>module_interface:function(ObjRef, [{timeout, Timeout}], ... Arguments ...)</c>,
instead of <c>module_interface:function(ObjRef, ... Arguments ...)</c>.
This is no longer the case and if the extra Timeout is used,
argument will override the configuration parameter <c>iiop_timeout</c>.
It is, however, not possible
to use <c>infinity</c> to override the Timeout parameter. The Timeout
option is also valid for objects which resides within the same Orber domain.</p>
</desc>
</func>
<func>
<name>iiop_connection_timeout() -> int() (milliseconds)</name>
<fsummary>Display the IIOP connection timeout value</fsummary>
<desc>
<p>This function returns the timeout value after which outgoing IIOP connections terminate.
It can be configured by setting the application variable
<em>iiop_connection_timeout TimeVal (seconds)</em>, if it is not set it will have the default value
<em>infinity</em>. The connection will not be terminated if there are
pending requests.</p>
<p>Note: the iiop_connection_timeout configuration parameter (TimeVal) may only range between 0 and 1000000 seconds.
Otherwise, the default value is used.</p>
</desc>
</func>
<func>
<name>iiop_connections() -> Result</name>
<name>iiop_connections(Direction) -> Result</name>
<fsummary>List all existing connections to/from other ORB's</fsummary>
<type>
<v>Direction = in | out | inout</v>
<v>Result = [{Host, Port}] | [{Host, Port, Interface}] | {'EXIT',Reason}</v>
<v>Host = string()</v>
<v>Port = integer()</v>
<v>Interface = string()</v>
<v>Reason = term()</v>
</type>
<desc>
<p>The list returned by this operation contain tuples of remote hosts/ports
Orber is currently connected to. If no Direction is not supplied, both
incoming and outgoing connections are included.</p>
<p>If a specific local interface has been defined for the connection,
this will be added to the returned tuple.</p>
</desc>
</func>
<func>
<name>iiop_connections_pending() -> Result</name>
<fsummary>List all connections to another ORB currently being set up</fsummary>
<type>

<v>Interface = string()</v>
<v>Reason = term()</v>
</type>
<desc>
<p>In some cases a connection attempt (i.e. trying to communicate with
another ORB) may block due to a number of reasons. This operation
allows the user to check if this is the case. The returned list
contain tuples of remote hosts/ports. Normally, the list is empty.</p>
<p>If a specific local interface has been defined for the connection,
this will be added to the returned tuple.</p>
</desc>
</func>
<func>
<name>iiop_in_connection_timeout() -> int() (milliseconds)</name>
<fsummary>Display the IIOP connection timeout value for incoming connections</fsummary>
<desc>
<p>This function returns the timeout value after which incoming IIOP
connections terminate. It can be configured by setting the application
variable <em>iiop_in_connection_timeout TimeVal (seconds)</em>, if it is
not set it will have the default value <em>infinity</em>. The connection
will not be terminated if there are pending requests.</p>
<p>Note: the iiop_in_connection_timeout configuration parameter (TimeVal) may
only range between 0 and 1000000 seconds. Otherwise, the default value is
used.</p>
</desc>
</func>
<func>
<name>iiop_acl() -> Result</name>
<fsummary>Return the ACL configuration</fsummary>
<type>
<v>Result = [{Direction, Filter}] | [{Direction, Filter, [Interface]}]</v>
<v>Direction = tcp_in | ssl_in | tcp_out | ssl_out</v>
<v>Filter = string()</v>
<v>Interface = string()</v>
</type>
<desc>
<p>Returns the ACL configuration. The <c>Filter</c> uses a extended format of
Classless Inter Domain Routing (CIDR). For example, <c>"123.123.123.10"</c> limits
the connection to that particular host, while <c>"123.123.123.10/17"</c> allows
connections to or from any host equal to the 17 most significant bits. Orber
also allow the user to specify a certain port or port range, for example,
<c>"123.123.123.10/17#4001"</c> and <c>"123.123.123.10/17#4001/5001"</c>
respectively. IPv4 or none compressed IPv6 strings are accepted. <br></br>
The list of <c>Interfaces</c>, IPv4 or IPv6 strings, are currently only used
for outgoing connections and may only contain <em>one</em> address. If set and
access is granted, Orber will use that local interface when connecting to the
other ORB. The module <seealso marker="orber_acl">orber_acl</seealso>
provides operations for evaluating the access control for filters and addresses.</p>
</desc>
</func>
<func>
<name>activate_audit_trail() -> Result</name>
<name>activate_audit_trail(Verbosity) -> Result</name>
<fsummary>Activate IIOP audit/trail</fsummary>
<type>
<v>Verbosity = stealth | normal | verbose</v>
<v>Result = ok | {error, Reason}</v>
<v>Reason = string()</v>
</type>
<desc>
<p>Activates audit/trail for all existing incoming and outgoing IIOP
connections. The <c>Verbosity</c> parameter, <c>stealth</c>,
<c>normal</c> or <c>verbose</c>, determines which of the built in
interceptors is used (<c>orber_iiop_tracer_stealth</c>,
<c>orber_iiop_tracer_silent</c> or <c>orber_iiop_tracer</c> respectively).
If no verbosity level is supplied, then the <c>normal</c> will be used.</p>
<p>In case Orber is configured to use other interceptors, the audit/trail
interceptors will simply be added to that list.</p>
</desc>
</func>
<func>
<name>deactivate_audit_trail() -> Result</name>
<fsummary>Deactivate IIOP audit/trail</fsummary>
<type>
<v>Result = ok | {error, Reason}</v>
<v>Reason = string()</v>
</type>
<desc>
<p>Deactivates audit/trail for all existing incoming and outgoing IIOP
connections. In case Orber is configured to use other interceptors,
those will still be used.</p>
</desc>
</func>
<func>
<name>add_listen_interface(IP, Type) -> Result</name>
<name>add_listen_interface(IP, Type, Port) -> Result</name>
<name>add_listen_interface(IP, Type, ConfigurationParameters) -> Result</name>
<fsummary>Add a new listen process for incoming connection</fsummary>
<type>
<v>IP = string</v>
<v>Type = normal | ssl</v>
<v>Port = integer() > 0</v>
<v>ConfigurationParameters = [{Key, Value}]</v>
<v>Key = flags | iiop_in_connection_timeout | iiop_max_fragments | iiop_max_in_requests | interceptors | iiop_port | iiop_ssl_port | ssl_server_options</v>
<v>Value = as described in the User's Guide</v>
<v>Result = {ok, Ref} | {error, Reason} | {'EXCEPTION', #'BAD_PARAM'{}}</v>
<v>Ref = #Ref</v>
<v>Reason = string()</v>
</type>
<desc>
<p>Create a new process that handle requests for creating a new incoming
IIOP connection via the given interface and port. If the latter is
excluded, Orber will use the value of the <c>iiop_port</c> or
<c>iiop_ssl_port</c> configuration parameters.
The <c>Type</c> parameter determines if it is
supposed to be IIOP or IIOP via SSL. If successful, the returned
<c>#Ref</c> shall be passed to <c>orber:remove_listen_interface/1</c>
when the connection shall be terminated.</p>
<p>It is also possible to supply configuration parameters that override
the global configuration. The <em>iiop_in_connection_timeout</em>,
<em>iiop_max_fragments</em>, <em>iiop_max_in_requests</em> and
<em>interceptors</em> parameters simply overrides the global
counterparts (See the
<seealso marker="ch_install#config">Configuration</seealso> chapter
in the User's Guide).
But for the following parameters there are a few restrictions:</p>
<list type="bulleted">
<item><em>flags</em> - currently it is only possible to override the global
setting for the <c>Use Current Interface in IOR</c> and
<c>Exclude CodeSet Component</c> flags.</item>
<item><em>iiop_port</em> - requires that <c>Use Current Interface in IOR</c>
is activated and the supplied <c>Type</c> is <c>normal</c>. If so,
exported IOR:s will contain the IIOP port defined by this configuration
parameter. Otherwise, the global setting will be used.</item>
<item><em>iiop_ssl_port</em> - almost equivalent to <c>iiop_port</c>.
The difference is that <c>Type</c> shall be <c>ssl</c> and that
exported IOR:s will contain the IIOP via SSL port defined by this configuration
parameter.</item>
</list>
<p>If it is not possible to add a listener based on the supplied interface
and port, the error message is one of the ones described in <c>inet</c>
and/or <c>ssl</c> documentation.</p>
</desc>
</func>
<func>
<name>remove_listen_interface(Ref) -> ok</name>
<fsummary>Terminate listen process for incoming connection</fsummary>
<type>
<v>Ref = #Ref</v>
</type>
<desc>
<p>Terminates the listen process, associated with the supplied <c>#Ref</c>,
for incoming a connection. The Ref parameter is the return value from
the <c>orber:add_listen_interface/2/3</c> operation. When terminating
the connection, all associated requests will not deliver a reply to
the clients.</p>
</desc>
</func>
<func>
<name>close_connection(Connection) -> Result</name>
<name>close_connection(Connection, Interface) -> Result</name>
<fsummary>Terminate outgoing connection(s)</fsummary>
<type>
<v>Connection = Object | [{Host, Port}]</v>
<v>Object = #objref (external)</v>
<v>Host = string()</v>
<v>Port = string()</v>
<v>Interface = string()</v>
<v>Result = ok | {'EXCEPTION', #'BAD_PARAM'{}}</v>
</type>
<desc>
<p>Will try to close all outgoing connections to the host/port combinations
found in the supplied object reference or the given list of hosts/ports.
If a <c>#'IOP_ServiceContext'{}</c> containing a local interface has been
used when communicating with the remote object
(see also <seealso marker="Module_Interface">Module_Interface</seealso>),
that interface shall be passed as the second argument. Otherwise, connections
via the default local interface, will be terminated.</p>
<p></p>
<note>
<p>Since several clients maybe communicates via the same connection,
they will be affected when invoking this operation. Other clients may
re-create the connection by invoking an operation on the target object.</p>
</note>
</desc>
</func>
<func>
<name>secure() -> no | ssl</name>
<fsummary>Display the security mode Orber is running in</fsummary>
<desc>
<p>This function returns the security mode Orber is running in, which is either no if it is an
insecure domain or the type of security mechanism used. For the moment the only security
mechanism is ssl. This is configured by setting the application variable

<desc>
<p>This function takes a list of SSL options as parameter and sets
it for the current process.</p>
</desc>
</func>
<func>
<name>objectkeys_gc_time() -> int() (seconds)</name>
<fsummary>Display the Object Keys GC time value</fsummary>
<desc>
<p>This function returns the timeout value after which after which terminated object keys,
related to servers started with the configuration parameter <c>{persistent, true}</c>,
will be removed.
It can be configured by setting the application variable <em>objectkeys_gc_time TimeVal (seconds)</em>,
if it is not set it will have the default value <em>infinity</em>. </p>
<p>Objects terminating with reason <em>normal</em> or <em>shutdown</em> are removed automatically.</p>
<p>Note: the objectkeys_gc_time configuration parameter (TimeVal) may only range between 0 and 1000000 seconds.
Otherwise, the default value is used.</p>

<v>Timeout = infinity | integer()</v>
<v>TableType = disc_copies | ram_copies</v>
<v>Priority = integer()</v>
</type>
<desc>
<p>This function installs all the necessary mnesia tables and
load default data in some of them. If one or more Orber tables
already exists the installation fails. The function
<em>uninstall</em> may be used, if it is safe, i.e., no other
application is running Orber.</p>
<p>Preconditions:</p>
<list type="bulleted">
<item>a mnesia schema must exist before the installation</item>
<item>mnesia is running on the other nodes if the new installation
shall be a multi node domain</item>
</list>
<p>Mnesia will be started by the function if it is not already running on
the installation node and if it was started it will be stopped
afterwards.</p>
<p>The options that can be sent to the installation program is:</p>
<list type="bulleted">
<item><c>{install_timeout, Timeout}</c> - this timeout is how long we
will wait for the tables to be created. The Timeout value can be
<em>infinity</em> or an integer number in milliseconds.
Default is infinity.</item>
<item><c>{ifr_storage_type, TableType}</c> - this option sets the
type of tables used for the interface repository.
The TableType can be disc_copies or ram_copies. Default is
disc_copies.</item>
<item><c>{initialreferences_storage_type, TableType}</c> - this option
sets the type of table used for storing initial references.
The TableType can be disc_copies or ram_copies. Default is
ram_copies.</item>
<item><c>{nameservice_storage_type, TableType}</c> - the default
behavior of Orber is to install the NameService as ram_copies.
This option makes it possible to change this to disc_copies. But
the user should be aware of that if a node is restarted, all
local object references stored in the NameService is not valid.
Hence, you cannot switch to disc_copies and expect exactly the same
behavior as before.</item>
<item><c>{load_order, Priority}</c> - per default the priority is set to 0.
Using this option it will change the priority of in which order
Mnesia will load Orber internal tables. For more information,
consult the Mnesia documentation.</item>
</list>

</func>
<func>
<name>uninstall() -> ok</name>
<fsummary>Uninstall the Orber application</fsummary>
<desc>
<p>This function stops the Orber application, terminates all server
objects and removes all Orber related mnesia tables.</p>
<p>Note: Since other applications may be running on the same node
using mnesia <em>uninstall</em> will not stop the mnesia application.</p>

<p>This function allows the user to configure Orber in, for example,
an Erlang shell. It is possible to invoke <c>configure</c> at any time
the keys specified above.</p>
<p>Any other key must be set before installing and starting Orber.</p>
<p>Trying to change the configuration in any other way is <em>NOT</em>
allowed since it may affect the behavior of Orber.</p>
<p>For more information regarding allowed values, see
<seealso marker="ch_install#config">configuration settings</seealso>
in the User's Guide.</p>

<note>
<p>Configuring the IIOP timeout values will not affect already
existing connections. If you want a guaranteed uniform behavior, you
must set these parameters from the start.</p>
