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 A-REX.

jobs

should/shouldn’t be migrated to
-i, --index=[-]name
explicitly select or reject an index server
-j, --joblist=filename
file where the jobs will be stored
-a, --all
all jobs specified in the jobfile will be tried migrated
-f, --forcemigration
force migration, ignore kill failure
-t, --timeout=seconds
timeout in seconds (default 20)

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 A-REX.
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 ARC1:https://knowarc1.grid.niif.hu:60000/arex ...
will migrate a to knowarc1.grid.niif.hu.
arcmigrate -q -ARC1:https://knowarc1.grid.niif.hu:60000/arex ...
will migrate a job to some other cluster than
knowarc1.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 -i ARC0:ldap://index1.nordugrid.org:2135/Mds-Vo-
name=NorduGrid,o=grid ...
use the NorduGrid index at index1.nordugrid.org
arcmigrate -i -ARC0:ldap://grid.tsl.uu.se:2135/Mds-Vo-
name=Sweden,o=grid ...
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).
