  • Updated these rpms from glite-wms_R_3_1_82 (build locally by giaco)
    • glite-wms-helper-3.1.17-5.slc4.i386.rpm
    • glite-wms-ism-3.1.15-2.slc4.i386.rpm
    • glite-wms-purger-3.1.8-3.slc4.i386.rpm

    • glite-wms-wmproxy-3.1.29-1.slc4.i386.rpm (compiled by maraska to fix some bugs)

  • To enable recovery set this parameter EnableRecovery = true; on glite_wms.conf (WorkloadManager section)

2007-10-10 (Ale)

  • Removed the line export http_proxy=myproxy.my.domain from /opt/glite/libexec/fetch-crl.sh
In the site-info.def file this variable SITE_HTTP_PROXY="myproxy.my.domain" is set, if not used please comment it. (This MUST be the default, but....)

2007-10-08 (Ale)

  • 30% of jobs fail due to this problem:
Status Reason:      LBProxy is enabled
Unable to query LB and LBProxy
edg_wll_QueryEvents[Proxy]
Exit code: 110
LB[Proxy] Error: Connection timed out
(edg_wll_gss_connect())

The jobs stay in the waiting state forever and they can be "resubmitted" through the command: glite-wms-job-submit --start _jobid_

2007-10-05 (Ale)

  • Found a bug on wmproxy: logging the Enqueued/OK events the "queue" parameter is not set
    • The symptom is: Status Reason: cannot retrieve jdl
    • The real problem: glite-lb-proxy[8426]: Message incomplete (Message incomplete, missing or empty field DG.ENQUEUED.QUEUE.)

2007-10-04 (Ale)

Configure jobdir
  • Set jobdir ad input method for workload-manager instead of filelist
    • Set these variables in the glite_wms.conf file (WorkloadManager section)
      • DispatcherType = "jobdir";
      • Input = "${GLITE_LOCATION_VAR}/workload_manager/jobdir";
    • Create these directories and then give the ownership to glite.glite
      • /var/glite/workload_manager/jobdir/new/
      • /var/glite/workload_manager/jobdir/old/
      • /var/glite/workload_manager/jobdir/tmp/

  • Add the proper VO entry in the /etc/grid-security/groupmapfile: e.g.

  • Configure the gridftp server:
