Constructor & Destructor Documentation

SALOME_ContainerManager::SALOME_ContainerManager	(	CORBA::ORB_ptr	orb,
		PortableServer::POA_var	poa,
		SALOME_ResourcesManager *	rm,
		SALOME_NamingService *	ns
	)

Constructor

Parameters:

orb	Define a CORBA single thread policy for the server, which avoid to deal with non thread-safe usage like Change_Directory in SALOME naming service

SALOME_ContainerManager::~SALOME_ContainerManager

(

)

destructor

Member Function Documentation

Engines::Container_ptr SALOME_ContainerManager::GiveContainer

(

const Engines::ContainerParameters &

params

)

Give a suitable Container given constraints.

CORBA Method:

Parameters:

params

Container Parameters required for the container

Returns:

the container or nil

void SALOME_ContainerManager::ShutdownContainers

(

)

Loop on all the containers listed in naming service, ask shutdown on each.

CORBA Method:

void SALOME_ContainerManager::Shutdown

(

)

shutdown all the containers, then the ContainerManager servant

CORBA method:

Engines::Container_ptr SALOME_ContainerManager::FindContainer	(	const Engines::ContainerParameters &	params,
		const Engines::ResourceList &	possibleResources
	)		[protected]

Find a container given constraints (params) on a list of machines (possibleComputers)

Engines::Container_ptr SALOME_ContainerManager::FindContainer	(	const Engines::ContainerParameters &	params,
		const std::string &	resource
	)		[protected]

Find a container given constraints (params) on a machine (theMachine)

std::string SALOME_ContainerManager::BuildCommandToLaunchRemoteContainer	(	const std::string &	resource_name,
		const Engines::ContainerParameters &	params,
		const std::string &	container_exe = "SALOME_Container"
	)		[protected]

Builds the script to be launched

If SALOME Application not defined ($APPLI), see BuildTempFileToLaunchRemoteContainer()

Else rely on distant configuration. Command is under the form (example): ssh user distantPath/runRemote.sh hostNS portNS WORKINGDIR workingdir \ SALOME_Container containerName &"

• where user is ommited if not specified in CatalogResources,
• where distant path is always relative to user $HOME, and equal to $APPLI if not specified in CatalogResources,
• where hostNS is the hostname of CORBA naming server (set by scripts to use to launch SALOME and servers in $APPLI: runAppli.sh, runRemote.sh)
• where portNS is the port used by CORBA naming server (set by scripts to use to launch SALOME and servers in $APPLI: runAppli.sh, runRemote.sh)
• where workingdir is the requested working directory for the container. If WORKINGDIR (and workingdir) is not present the working dir will be $HOME

std::string SALOME_ContainerManager::BuildCommandToLaunchLocalContainer	(	const Engines::ContainerParameters &	params,
		const std::string &	machinesFile,
		const std::string &	container_exe = "SALOME_Container"
	)		[protected]

builds the command to be launched.

std::string SALOME_ContainerManager::BuildTempFileToLaunchRemoteContainer	(	const std::string &	resource_name,
		const Engines::ContainerParameters &	params
	)		throw (SALOME_Exception) [protected]

Builds in a temporary file the script to be launched.

Used if SALOME Application ($APPLI) is not defined. The command is build with data from CatalogResources, in which every path used on remote computer must be defined.

void SALOME_ContainerManager::RmTmpFile

(

std::string &

tmpFileName

)

[protected]

removes the generated temporary file in case of a remote launch.

void SALOME_ContainerManager::AddOmninamesParams

(

std::string &

command

)

const [protected]

add to command all options relative to naming service.

void SALOME_ContainerManager::AddOmninamesParams

(

std::ostringstream &

oss

)

const [protected]

add to command all options relative to naming service.

void SALOME_ContainerManager::AddOmninamesParams

(

std::ofstream &

fileStream

)

const [protected]

add to command all options relative to naming service.

std::string SALOME_ContainerManager::BuildTemporaryFileName

(

)

const [protected]

generate a file name in /tmp directory
