Hi all
Maybe somone could just point me in the right direction (or to the right
section in the manual) please.
I am struggling to understand (and therefore to get it working) how to access
an object om another machine. I understand that the ORB's are supposed to
handle this transparantly, which brings me to the point: how do I make them
aware of each other? In the config file I have set up the two ORB's as
defaultInitRef. Also, how are the endpoints supposed to be configured? Are
they only allowed to be on the host machine? I ask because it complains when I
enter the other machines' name and port as an endpoint.
I must add that I am trying to get the omniORB4 eg3_impl and eg3_clt examples
working in this way; if I understand CORBA correctly, it should not be
necessary to change the source code, right?
I have attached my config files of the two machines for your inspection.
Thank You
Johan

#
# The default value of this flag is true, so invalid messages are
# rejected. If you set it to zero, the ORB will silently skip the
# unread part. The problem with this behaviour is that the header
# message size may actually be garbage, caused by a bug in the

#
# Specify the objects the ORB should return in response to calls to
# resolve_initial_references.
#
# There can be more than one configuration line defining InitRef.
# Each line adds one initial reference to the ORB.
#
# Here are some valid examples:
#
# Specify the root context of the Naming Service. (Notice the end of line
# continuation marker '\'
#
# InitRef = NameService=IOR:010000002800000049444c3a6f6d672e6f72672f436f734\

#
# Alternatively, and more cleanly, specify the Naming service with a

#
# Specify the Trading service and the interface repository using corbaloc:

#
# The default for the set of initial references is empty.
############################################################################
# DefaultInitRef
#
# DefaultInitRef provides a prefix string which is used to resolve
# otherwise unknown names. When resolve_initial_references() is unable to
# resolve a name which has been specifically configured (with InitRef),
# it constructs a string consisting of the default prefix, a `/' character,
# and the name requested. The string is then fed to string_to_object().
# For example, if DefaultInitRef is set up like this:
DefaultInitRef = corbaloc:iiop:fee.dsp.sun.ac.za/NameService
# A call to resolve_initial_references("MyService") will return the object
# reference denoted by `corbaloc::myhost.example.com/MyService'.
#
# The default is empty.
############################################################################
# clientTransportRule
#
# When the client receives an IOR that defines 1 or more ways to contact
# the server, the rules in clientTransportRule filter and prioritise
# the order in which the transports are used.
#
# There can be more than one configuration line of this type.
# Each line adds one rule to the selection process. The rules are applied
# in the order they are defined. The relative positions of the rules define
# the relative priority. The first rule has the highest priority.
#
# The syntax of a rule is as follows:
# clientTransportRule = [^]<address mask> [action]+
#
# <address mask> can be:
# 1. localhost the address is this machine
# 2. w.x.y.z/m1.m2.m3.m4 IPv4 address with the bits selected by
# the mask. e.g. 172.16.0.0/255.240.0.0
# 3. * the wildcard that matches any address
#
# <action>+ can be one or more of the following:
# 1. none Do not use this address
# 2. tcp,ssl,unix Use the 3 transports in the specified order
# if any or all of them are available
# 3. bidir Any connection to this address should be
# used bidirectionally.
#
# The optional prefix ^ before <address mask>, if present, causes
# the ORB to remove previously declared clientTransportRules from
# its internal store because adding the current rule.
#
# By default, no rule is defined. The ORB implicitly uses the following
# rule:
# clientTransportRule = * unix,tcp,ssl
# If any rule is specified, no implicit rule will be applied.
#
# Given an IOR, for each of the addresses within it, the ORB matches the
# address to the rules. If one is found, the position of the matched rule
# and the action is noted. If the action is none, the address is discarded.
# If the action does not contain the transport the address is specified for,
# e.g. the action is "ssl" but the address is "tcp", the address is
# discarded. Otherwise, the address and action is entered as one of the
# candidates to use. Having gone through all the addresses, the candidiates
# available are then ordered based on the priority of the matching rules and
# used accordingly.
#
# Here are some example usages:
#
# A) Restrict to only contacting server on the same host:
# clientTransportRule = localhost unix,tcp
# = * none
# B) Use tcp to contact servers in the intranet and must use bidirectional
# ssl otherwise.
# clientTransportRule = 172.16.0.0/255.240.0.0 unix,tcp
# = * bidir,ssl
# C) When a fast network (192.168.1.0) exists in the cluster, use it in
# preference to the external network.
# clientTransportRule = 192.168.1.0/255.255.255.0 unix,tcp
# clientTransportRule = 172.16.0.0/255.240.0.0 unix,tcp

# endPoint
# endPointNoPublish
# endPointNoListen
# endPointPublishAllIFs
#
# There are 3 possible way to specify the endpoints a server should create.
# The 3 forms differ in the following ways:
# endPoint - create, listen on the connection and publish it in IORs
# endPointNoPublish - same as endPoint but do not publish it in IORs
# endPointNoListen - only publish it in IORs
#
# There can be more than one configuration line defining endPoints.
# Each line adds one endpoint to the server.
#
# Each configuration line can start with the keyword 'endPoint', e.g.
# endPoint = giop:tcp:neem:12345
# endPoint = giop:ssl:neem:23456
#
# Or a short hand form can be used, like this:
#
# endPoint = giop:tcp:neem:12345
# = giop:ssl:neem:23456
#
# The value of an endPoint configuration is a transport specific string.
# The transport strings recongised by the ORB and its supported transports
# are:
# 1. giop:tcp:[<host>]:[<port>]
# The <host> and <port> parameter are optional. If either or
# both are missing, the ORB fills in the blank. For example,
# "giop:tcp::" will cause the ORB to pick an arbitrary tcp port
# as the endpoint and it will pick one IP address of the host
# as the host name.
#
# 2. giop:ssl:[<host>]:[<port>]
# Similar to the tcp transport except that SSL is run on top
# of the tcp connection.
#
# 3. giop:unix:[<filename>]
# Create a unix domain socket and bind to the file with pathname
# <filename>. If <filename> is not specified, e.g. "giop:unix:",
# the ORB would pick a file name based on the process ID and
# the current timestamp.
# Therefore, if one wants to write an application that always
# restarts to use the same file to bind to its unix domain
# socket, a filename should be specified in the transport string.
#
# It is possible to use the ORB's transport extension framework to add
# a new transport to the ORB. In that case, the transport must define its
# own transport string format and must obey the colon separation rule.
# For example, if one is to create a transport which executes an arbitrary
# shell script and let the ORB use its stdin and stdout for sending and
# receiving giop messages, a transport string could look like this:
# giop:shell:magic_gw
# ^ ^
# | +--------- transport specific part
# +--------------- transport name
#
# By default, no endPoint configuration is defined. In this case the ORB
# will create just 1 tcp endpoint as if the line:
# endPoint = giop:tcp::
# is specified in the configuration file
#
# Other than tcp, none of the transports are guaranteed to be available
# on all platforms. If one specifies say:
# endPoint = giop:ssl::
# and the ORB cannot initialise an ssl endpoint, the INITIALIZE exception
# will be raised. Even though ssl is supported on a platform, its transport
# is implemented as a separate shared library and must be linked with the
# application for the ORB to initialise the endpoint.
#
# Here are some examples of valid endPoint configurations:
#
#endPoint = giop:tcp:fee.dsp.sun.ac.za:56791
#endPoint = giop:tcp:michelle.dsp.sun.ac.za:56791
#endPoint = giop:unix::
# = giop:ssl::
#
# endPointNoPublish = giop:tcp::
# = giop:unix:
# = giop:ssl::
#
# endPointNoListen = giop:tcp:192.168.1.1:12345
#
#
# If the endPointPublishAllIFs boolean parameter is set to true, all
# non-loopback IP network interfaces are published in IORs, rather
# than just the first one.

# serverTransportRule

# clientTransportRule
#
# When the client receives an IOR that defines 1 or more ways to contact
# the server, the rules in clientTransportRule filter and prioritise
# the order in which the transports are used.
#
# There can be more than one configuration line of this type.
# Each line adds one rule to the selection process. The rules are applied
# in the order they are defined. The relative positions of the rules define
# the relative priority. The first rule has the highest priority.
#
# The syntax of a rule is as follows:
# clientTransportRule = [^]<address mask> [action]+
#
# <address mask> can be:
# 1. localhost the address is this machine
# 2. w.x.y.z/m1.m2.m3.m4 IPv4 address with the bits selected by
# the mask. e.g. 172.16.0.0/255.240.0.0
# 3. * the wildcard that matches any address
#
# <action>+ can be one or more of the following:
# 1. none Do not use this address
# 2. tcp,ssl,unix Use the 3 transports in the specified order
# if any or all of them are available
# 3. bidir Any connection to this address should be
# used bidirectionally.
#
# The optional prefix ^ before <address mask>, if present, causes
# the ORB to remove previously declared clientTransportRules from
# its internal store because adding the current rule.
#
# By default, no rule is defined. The ORB implicitly uses the following
# rule:
# clientTransportRule = * unix,tcp,ssl
# If any rule is specified, no implicit rule will be applied.
#
# Given an IOR, for each of the addresses within it, the ORB matches the
# address to the rules. If one is found, the position of the matched rule
# and the action is noted. If the action is none, the address is discarded.
# If the action does not contain the transport the address is specified for,
# e.g. the action is "ssl" but the address is "tcp", the address is
# discarded. Otherwise, the address and action is entered as one of the
# candidates to use. Having gone through all the addresses, the candidiates
# available are then ordered based on the priority of the matching rules and
# used accordingly.
#
# Here are some example usages:
#
# A) Restrict to only contacting server on the same host:
# clientTransportRule = localhost unix,tcp
# = * none
# B) Use tcp to contact servers in the intranet and must use bidirectional
# ssl otherwise.

# endPoint
# endPointNoPublish
# endPointNoListen
# endPointPublishAllIFs
#
# There are 3 possible way to specify the endpoints a server should create.
# The 3 forms differ in the following ways:
# endPoint - create, listen on the connection and publish it in IORs
# endPointNoPublish - same as endPoint but do not publish it in IORs
# endPointNoListen - only publish it in IORs
#
# There can be more than one configuration line defining endPoints.
# Each line adds one endpoint to the server.
#
# Each configuration line can start with the keyword 'endPoint', e.g.
# endPoint = giop:tcp:neem:12345
# endPoint = giop:ssl:neem:23456
#
# Or a short hand form can be used, like this:
#
# endPoint = giop:tcp:neem:12345
# = giop:ssl:neem:23456
#
# The value of an endPoint configuration is a transport specific string.
# The transport strings recongised by the ORB and its supported transports
# are:
# 1. giop:tcp:[<host>]:[<port>]
# The <host> and <port> parameter are optional. If either or
# both are missing, the ORB fills in the blank. For example,
# "giop:tcp::" will cause the ORB to pick an arbitrary tcp port
# as the endpoint and it will pick one IP address of the host
# as the host name.
#
# 2. giop:ssl:[<host>]:[<port>]
# Similar to the tcp transport except that SSL is run on top
# of the tcp connection.
#
# 3. giop:unix:[<filename>]
# Create a unix domain socket and bind to the file with pathname
# <filename>. If <filename> is not specified, e.g. "giop:unix:",
# the ORB would pick a file name based on the process ID and
# the current timestamp.
# Therefore, if one wants to write an application that always
# restarts to use the same file to bind to its unix domain
# socket, a filename should be specified in the transport string.
#
# It is possible to use the ORB's transport extension framework to add
# a new transport to the ORB. In that case, the transport must define its
# own transport string format and must obey the colon separation rule.
# For example, if one is to create a transport which executes an arbitrary
# shell script and let the ORB use its stdin and stdout for sending and
# receiving giop messages, a transport string could look like this:
# giop:shell:magic_gw
# ^ ^
# | +--------- transport specific part
# +--------------- transport name
#
# By default, no endPoint configuration is defined. In this case the ORB
# will create just 1 tcp endpoint as if the line:
# endPoint = giop:tcp::
# is specified in the configuration file
#
# Other than tcp, none of the transports are guaranteed to be available
# on all platforms. If one specifies say:
# endPoint = giop:ssl::
# and the ORB cannot initialise an ssl endpoint, the INITIALIZE exception
# will be raised. Even though ssl is supported on a platform, its transport
# is implemented as a separate shared library and must be linked with the
# application for the ORB to initialise the endpoint.
#
# Here are some examples of valid endPoint configurations:
#
# endPoint = giop:tcp::
# endPoint = giop:unix:
# = giop:ssl::
#
# endPointNoPublish = giop:tcp::
# = giop:unix:
# = giop:ssl::
#
# endPointNoListen = giop:tcp:192.168.1.1:12345
#
#
# If the endPointPublishAllIFs boolean parameter is set to true, all
# non-loopback IP network interfaces are published in IORs, rather
# than just the first one.

#
# 1 means that after dispatching an upcall in thread pool mode, the

# returning to the pool. This leads to less thread switching for
# series of calls from a single client, but is less fair if there
# are concurrent clients.

# objectTableSize
#
# Hash table size of the Active Object Map. If this is zero, the ORB
# uses a dynamically resized open hash table. This is normally the
# best option, but it leads to less predictable performance since
# any operation which adds or removes a table entry may trigger a
# resize. If you set this to a non-zero value, the hash table has
# the specified number of entries, and is never resized. Note that
# the hash table is open, so this does not limit the number of
# active objects, just how efficiently they can be located.

# Valid values = (n >= 0)

# This variable can be used to set a time-out for calls being held

# The POA specification requires that object ids in POAs with the

# POA has the correct behaviour; with false, the POA uses the old

# supportBootstrapAgent
#
# Applies to the server side. 1 means enable the support for Sun's
# bootstrap agent protocol. This enables interoperability between omniORB
# servers and Sun's javaIDL clients. When this option is enabled, an
# omniORB server will respond to a bootstrap agent request.
