NAME

       arcmigrate - ARC Migration

DESCRIPTION

       The  arcmigrate  command is used for migrating queued jobs from one cluster to another cluster. Currently
       migration only works between clusters running the A-REX BES interface.

              a file containing a list of jobIDs

       -a, --all
              migration will be attempted all jobs specified in the jobfile

       -o, --jobids-to-file=filename
              the IDs of the submitted jobs will be appended to this file

       -i, --jobids-from-file=filename
              a file containing a list of jobIDs

       -f, --force
              force migration, ignore kill failure

       -P, --listplugins
              list the available plugins

       -t, --timeout=seconds
              timeout in seconds (default 20)

       -z, --conffile=filename
              configuration file (default ~/.arc/client.conf)

              print help

ARGUMENTS

       jobid ...
              id of a queued job which should be migrated

EXTENDED DESCRIPTION

The arcmigrate command is used for migrating jobs which are queuing in the batch system. Currently only
jobs having status Queuing can be migrated, and the command is only supported for migration between
clusters running the A-REX BES interface.

The --qluster option can be used to force the job to be migrated to a particular cluster, or to reject
migration to a particular cluster. The --qluster option can be repeated several times. The name of the
cluster should be given in the format

[ARC1:][protocol://]hostname[:port]/path

Examples:

arcmigrate -q example.org:60000/arex ...
will migrate the job to example.org.

arcmigrate -q -example.org:60000/arex ...
will migrate the job to some other cluster than interop.grid.niif.hu.

Jobs to be migrated can be specified in serveral ways. Job IDs can be specified as arguments on the
command line, clusters holding queued jobs can be specified with the --cluster option, and to migrate all
jobs in the jobfile the --all option can be given.

If the job(s) is successfully migrated a jobid(s) is printed to stdout. This jobid uniquely identifies
the job while it is being executed.

Information about active jobs, including the old job id of the migrated job, are stored in a local
joblist file. By using the --joblist option a customized location for this file can be defined. If this
option is used when migrating a job using arcmigrate, the same joblist file must be specified using the
--joblist option for all subsequent handling of the job using arcstat(1), arcget(1), etc.

The arcmigrate command locates the available clusters by querying information index servers. Which
servers to query can be specified by giving the --index option to the command. The name of the index
server should be given in the format

Flavor:protocol://hostname[:port]/path

Example:

arcmigrate -g index1.nordugrid.org ...
use the NorduGrid index at index1.nordugrid.org

arcmigrate -g -grid.tsl.uu.se ...
do not use the Sweden index at grid.tsl.uu.se

FILES

       ~/.arc/client.conf
              Some  options can be given default values by specifying them in the ARC client configuration file.
              By using the --conffile option a different configuration file can be used than the default.

       ~/.arc/jobs.xml
              This a local list of the user's active jobs. When a job is successfully migrated the old jobid  is
              removed  and  the new is added to this list. This list is used as the list of all active jobs when
              the user specifies the --all option to the various NorduGrid ARC user interface commands. By using
              the --joblist option a different file can be used than the default.

ENVIRONMENT VARIABLES

       X509_USER_PROXY
              The location of the user's Grid proxy file. Shouldn't be set unless the proxy is in a non-standard
              location.

       ARC_LOCATION
              The location where ARC is installed can be specified  by  this  variable.  If  not  specified  the
              install location will be determined from the path to the command being executed, and if this fails
              a WARNING will be given stating the location which will be used.

       ARC_PLUGIN_PATH
              The location of ARC plugins can be specified by this variable. Multiple locations can be specified
              by  separating  them  by  :  (;  in  Windows). The default location is $ARC_LOCATION/lib/arc (\ in
              Windows).
