Member Function Documentation

◆ Added()

void XrdCmsFinderTRG::Added	(	const char *	path,
		int	Pend = `0`
	)

virtual

Notify the cms of a newly added file or a file whose state has changed on a data server node.

Parameters

path	The logical file name.
Pend	When true, the file is scheduled to be present in the future (e.g. copied in).

Reimplemented from XrdCmsClient.

◆ Configure()

int XrdCmsFinderTRG::Configure	(	const char *	cfn,
		char *	Parms,
		XrdOucEnv *	EnvInfo
	)

virtual

Configure the client object.

Parameters

cfn	The configuration file name.
Parms	Any parameters specified in the cmslib directive. If none, the pointer may be null.
EnvInfo	Environmental information of the caller.

Returns: Success !0 Failure =0

Implements XrdCmsClient.

◆ Hookup()

void XrdCmsFinderTRG::Hookup ( )

private

◆ Locate()

int XrdCmsFinderTRG::Locate	(	XrdOucErrInfo &	Resp,
		const char *	path,
		int	flags,
		XrdOucEnv *	Info = `0`
	)

virtual

Retrieve file location information.

Parameters

Resp	Object where message or response is to be returned.
path	The logical path whise location is wanted.
flags	One or more of the following: SFS_O_LOCATE - return the list of servers that have the file. Otherwise, redirect to the best server for the file. SFS_O_NOWAIT - w/ SFS_O_LOCATE return readily available info. Otherwise, select online files only. SFS_O_CREAT - file will be created. SFS_O_NOWAIT - select server if file is online. SFS_O_REPLICA - a replica of the file will be made. SFS_O_STAT - only stat() information wanted. SFS_O_TRUNC - file will be truncated. For any the the above, additional flags are passed: SFS_O_META - data will not change (inode operation only) SFS_O_RESET - reset cached info and recaculate the location(s). SFS_O_WRONLY - file will be only written (o/w RDWR or RDONLY). SFS_O_RDWR - file may be read and written (o/w WRONLY or RDONLY).
Info	Associated environmental information for arg2 (e.g., cgi info which can be retrieved by Env1->Env(<len>)).

Returns: As explained under "return conventions".

Implements XrdCmsClient.

◆ Managers()

XrdOucTList * XrdCmsFinderTRG::Managers ( )

inlinevirtual

Obtain the list of cmsd's being used by a manager node along with their associated index numbers, origin 1.

Returns: The list of cmsd's being used. The list is considered permanent and is not deleted.

Reimplemented from XrdCmsClient.

References myManList.

◆ Prepare()

int XrdCmsFinderTRG::Prepare	(	XrdOucErrInfo &	Resp,
		XrdSfsPrep &	pargs,
		XrdOucEnv *	Info = `0`
	)

inlinevirtual

Start the preparation of a file for future processing.

Parameters

Resp	Object where message or response is to be returned.
pargs	Information on which and how to prepare the file.
Info	Associated environmental information.

Returns: As explained under "return conventions".

Reimplemented from XrdCmsClient.

◆ Process()

int XrdCmsFinderTRG::Process ( XrdCmsRRData & Data )

private

◆ PutInfo()

void XrdCmsFinderTRG::PutInfo	(	XrdCmsPerfMon::PerfInfo &	info,
		bool	alert = `false`
	)

virtual

Report performance statistics as load values from 0 to 100. The performance monitor plugin may call this method to asynchronously report performance via the passed XrdCmsPerfMon object during configuration.

Parameters

info	Reference to the structure that should be filled out with load values. See the PerfInfo structure.
alert	When true, load information is forcibly sent to the cluster's manager. Otherwise, it is only sent if it significantly changes. See the cms.sched directive fuzz parameter.

Reimplemented from XrdCmsPerfMon.

◆ Release()

int XrdCmsFinderTRG::Release ( int n )

virtual

Increases the amount of resource available. When transitioning from a a non-positive to a positive resource amount, perform a resume so that additional clients may be dispatched to this data server.

Parameters

n	The value to add to the resources available (default 1). The total amount is capped by the amount specified by Resource().

Returns: The amount of resource left.

Reimplemented from XrdCmsClient.

◆ Removed()

void XrdCmsFinderTRG::Removed ( const char * path )

virtual

Notify the cmsd that a file or directory has been deleted. It is only called called on a data server node.

Parameters

path	The logical file name that was removed.

Reimplemented from XrdCmsClient.

◆ Reserve()

int XrdCmsFinderTRG::Reserve ( int n )

virtual

Decreases the amount of resources available. When the available resources becomes non-positive, perform a temporary suspend to prevent additional clients from being dispatched to this data server.

Parameters

n	The value by which resources are decreased (default 1).

Returns: The amount of resource left.

Reimplemented from XrdCmsClient.

◆ Resource()

int XrdCmsFinderTRG::Resource ( int n )

virtual

Enables the Reserve() & Release() methods.

Parameters

n	a positive integer that specifies the amount of resource units that are available. It may be reset at any time.

Returns: The previous resource value. This first call returns 0.

Reimplemented from XrdCmsClient.

◆ Resume()

void XrdCmsFinderTRG::Resume ( int Perm = 1 )

virtual

Resume service after a suspension.

Parameters

Perm	When true the resume persist across server restarts. Otherwise, it is treated as a temporary request.

Reimplemented from XrdCmsClient.

◆ RunAdmin()

int XrdCmsFinderTRG::RunAdmin	(	char *	Path,
		const char *	vnid
	)

◆ RunPM()

void * XrdCmsFinderTRG::RunPM ( )

◆ Space()

int XrdCmsFinderTRG::Space	(	XrdOucErrInfo &	Resp,
		const char *	path,
		XrdOucEnv *	Info = `0`
	)

inlinevirtual

Obtain the overall space usage of a cluster. Called only on manager nodes.

Parameters

Resp	Object to hold response or error message.
path	Associated logical path for the space request.
Info	Associated cgi information for path.

Returns: Space information as defined by the response to kYR_statfs. For a typical implementation see XrdCmsNode::do_StatFS().

Implements XrdCmsClient.

◆ Start()

void * XrdCmsFinderTRG::Start ( )

◆ Suspend()

void XrdCmsFinderTRG::Suspend ( int Perm = 1 )

virtual

Suspend service.

Parameters

Perm	When true the suspend persist across server restarts. Otherwise, it is treated as a temporary request.

Reimplemented from XrdCmsClient.

◆ Utilization()

void XrdCmsFinderTRG::Utilization	(	unsigned int	util,
		bool	alert = `false`
	)

virtual

Report utilization of this server. This may be used in lieu of general performance metric reporting. For consistent results use only one method.

Parameters

util	A value from 0 to 100 representing utilization. Values greater than 100 are set to be 100.
alert	When true the utilization is forcibly report to the cluster managers. Otherwise, reporting is done only when it will significantly change server selection.

Reimplemented from XrdCmsClient.
