2. Operational issues

2.1 Report from DMSU

ARGUS/WMS Certificate Chain Mixups

  • Affecting several sites, where WMS is unable to make SSL connection to ARGUS.
  • With all probability this is a combination of using curl from the SL6 distribution, which in built with NSS SSL rather than OpenSSL and, as such, does not really support proxy certificates, and a bug in Java, hopefully fixed since Java 7 Update 60.
  • Related issues:
  • This issue is already being investigated at 3rd level but PTs cannot decide who is responsible ant DMSU is overseeing.

2.2 APEL multicore accounting

As many EGI user communities are now exploiting multicore hardware it is important for them that accounting correctly reflects the usage made of cores and cpus. At the December Operations Management Board (OMB) it was decided to ask all sites using the APEL client to configure it to publish the number of cores used by jobs.

To enable multicore accounting, you will need to edit the configuration file for the apel parser. This is the software which parses blah logs and batch logs to produce accounting records. The configuration file is usually found at /etc/apel/parser.cfg. In the section labelled [batch], change:

parallel = false


parallel = true

This will enable multicore reporting for all future accounting data. Please note that this does not change historical data. Also note that republishing old data is not sufficient to show multicore information - the log files will need to be reparsed. If you wish to republish old data with multicore enabled, please open a GGUS ticket with the APEL team so that we can help you with the process.

If you use the SGE parser, please be aware that it only reports on the number of processors used in a job. It does not report the number of nodes. If you know how to get around this limitation, then please get in touch with the APEL team at

The multicore accounting data can currently be seen here:

Drill down to your site and select the grouping "Show data for: Submitting Host" as a function of: "Number of Processors".

Values of 0 mean the parallel option was false when the data were published. The Submitting Host is a new feature in the accounting portal which lets a site see in more detail which CEs are publishing.

2.3 EMI-2 decommissioning

  • UMD2 APEL clients - GGUS: Sites using UMD2 APEL clients - 3 NGI didn't finish the update:
    • NGI_UA, NGI_DE, ROC_Asia/Pacific
      • especially GOeGrid, MY-UPM-BIRUNI-01 are still using UMD2 client
  • IMPORTANT - switching-off UMD2/EMI2 APEL service - Friday 16th January

2.4 dCache 2.2.X decommissioning

   1. NGI_DE/GoeGrid
   ggus: - in progress (admins need more time - till the end of 2014)
   gocdb: - no service downtime
   nagios: - still critical 
   ggus: - in progress (admins need more time - till December)
   gocdb: - no service downtime
   nagios: - still critical

2.5 Configuration of the new VOMS server for OPS in the infrastructure AND SAM

2.6 SAM Nagios probes re-factoring

2.7 MySQL 5.0 EOL

  • discussed during URT meeting, 29.09.2014
  • MySQL versions available:
  • SL5:
    • mysql-*5.0.95* -> MySQL 5.0
    • mysql51-*5.1.70* -> MySQl 5.1
    • mysql55-*5.5.32* -> MySQL 5.5
  • SL6:
    • mysql-*5.1.71 -> MySQL 5.1
  • Middleware dependancy on 'mysql-server':
    • VOMS - emi-voms-mysql - confirmed it should work with MySQL 5.1, as on SL6, but not tested
    • CREAM - emi-cream-ce - GGUS #106250
    • DPM - puppetlabs/mysql dependancy on "mysql-server",
    • STORM - storm-backend-server - confirmed it should work with MySQL 5.1, as on SL6, but not tested
    • L&B - glite-lb-server - under investigation - will be checked by the SoftwareProvisioning team on the EGI verification testbed
    • WMS - emi-wms - under investigation - will be checked by the SoftwareProvisioning team on the EGI verification testbed
  • Recommendation - site-admins must be made aware to avoid using MySQL v. 5.0, where possible.
