Be sure that the site's GIIS URL is contained in the Top level BDII/Information System your NGI will use for your certification. <!--Note that this BDII can also contain uncertified sites. -->
 
<br> Note that the examples here use the Italian NGI and sites. Please substitute '''YOUR OWN''' NGI and site credentials when running the test.
 
== lcg-CE checks  ==
 
Verify the authentication and authorization on the CE by running a simple command. i.e.
 
'''''$ globus-job-run inaf-ce-01.ct.pi2s2.it /bin/hostname'''''
 
(you could also use: /usr/bin/whoami, or whatever you want!!)
 
Check if the lcg-CE gridftp server is working
 
'''''$ globus-url-copy -dbg -v -vb file:/home/csys/goncalo/teste.txt gsiftp://ce02.lip.pt/tmp/txt'''''
 
'''''$ uberftp ce02.lip.pt'''''
 
<br> In case of pbs, check the WNs with the following command:
 
'''''$ globus-job-run pbs-enmr.cerm.unifi.it /usr/bin/pbsnodes -a'''''
 
Verify the functioning of the batch system: be careful that the queue you are querying really exists, and your VO is enabled on it. For example:
 
'''''$ globus-job-run ce02.lip.pt:2119/jobmanager-fork /bin/pwd'''''
 
'''''$ globus-job-run ce-cyb.ca.infn.it/jobmanager-lcglsf -queue poncert /bin/pwd'''''
 
check dgas processes on CE (with a ps ax| grep dgas)
 
== Cream-CE checks  ==
 
Open your browser to
 
'''''<nowiki>https://<hostname-of-cream-ce>:8443/ce-cream/services</nowiki>'''''
 
A page with link to the CREAM WSDL should be shown
 
Try a gsiftp (e.g. using globus-url-copy or @uberftp@@) towards that CREAM CE. E.g.:
 
'''''$ globus-url-copy gsiftp://&lt;hostname-of-cream-ce&gt;/opt/glite/yaim/etc/versions/ig-yaim file:/tmp/ig-version-test''''' 
 
Try the following command:
 
'''''$ glite-ce-allowed-submission &lt;&lt;hostname-of-cream-ce&gt;&gt;:8443'''''
 
It should report:
 
Job Submission to this CREAM CE is enabled 
 
Try a submission to Cream-CE using the glite-ce-job-submit command, e.g.:
 
$ /bin/cat sleep.jdl
 
[
executable="/bin/sleep";
arguments="1";
]
 
'''''$ glite-ce-job-submit -a -r &lt;hostname-of-cream-ce&gt;:8443/&lt;queue&gt; test.jdl''''' 
 
'''''$ glite-ce-job-submit -a -r ce-cr-02.ts.infn.it:8443/cream-lsf-cert sleep.jdl'''''
<nowiki>https://ce-cr-02.ts.infn.it:8443/CREAM127814374</nowiki>
 
Check the status of that job, which eventually should be DONE-OK
 
'''''$ glite-ce-job-status <nowiki>https://ce-cr-02.ts.infn.it:8443/CREAM127814374</nowiki>'''''
2010-07-27 11:55:37,986 WARN - No configuration file suitable for loading. Using built-in configuration
******  JobID=<nowiki>[https://ce-cr-02.ts.infn.it:8443/CREAM127814374]</nowiki>
      Status        = [DONE-OK]
      ExitCode      = [0]
 
Try a submission to that CE using the glite-ce-job-submit command, and then tries to cancel it (using the glite-ce-job-cancel command)
 
$ /bin/cat sleep2.jdl
 
[
executable="/bin/sleep";
arguments="1000";
]
 
$ glite-ce-job-submit -a -r cecream-cyb.ca.infn.it:8443/cream-lsf-poncert sleep2.jdl

== ARC CE checks  ==
 
A first test can be done using ARC's <font face="Courier New,Courier">ngstat</font> command:
 
'''''$ export X509_USER_PROXY=/etc/nagios/globus/userproxy.pem-ops'''''
'''''$ export LD_LIBRARY_PATH=/opt/nordugrid/lib64:/opt/nordugrid/lib'''''
'''''$ /opt/nordugrid/bin/ngstat -q -l -c &lt;CE hostname&gt; -t 20'''''
...
... plenty of output
...
 
If a [https://tomtools.cern.ch/confluence/display/SAM/SAM+setup+for+ARC+services monitoring host of your NGI] is available, then the probes can easily be executed from there:
 
Check the status of the CE with:
 
'''''$ /usr/libexec/grid-monitoring/probes/org.ndgf/ARCCE-status -H &lt;CE hostname&gt; -x /etc/nagios/globus/userproxy.pem-ops'''''
Status is active
 
Test gsiftp:
 
'''''$ /usr/libexec/grid-monitoring/probes/org.ndgf/ARCCE-auth -H &lt;CE hostname&gt; -x /etc/nagios/globus/userproxy.pem-ops'''''
gsiftp OK
 
Test the versions of the CA's:
 
'''''$ /usr/libexec/grid-monitoring/probes/org.ndgf/ARCCE-caver -H &lt;CE hostname&gt; -x /etc/nagios/globus/userproxy.pem-ops'''''
version = 1.38 - All CAs present
 
Check the versions of ARC and Globus:
 
'''''$ /usr/libexec/grid-monitoring/probes/org.ndgf/ARCCE-softver -H &lt;CE hostname&gt; -x /etc/nagios/globus/userproxy.pem-ops'''''
nordugrid-arc-0.8.3.1, globus-5.0.3
 
Copy a file:
 
'''''$ /usr/libexec/grid-monitoring/probes/org.ndgf/ARCCE-gridftp -H &lt;CE hostname&gt; -x /etc/nagios/globus/userproxy.pem-ops'''''
Job finished successfully
 
Submit a test job:
 
'''''$ /usr/libexec/grid-monitoring/probes/org.ndgf/ARCCE-jobsubmit -H &lt;CE hostname&gt; --vo ops -x /etc/nagios/globus/userproxy.pem-ops'''''
Job submission successful
 
Check the LFC:
 
'''''$ /usr/libexec/grid-monitoring/probes/org.ndgf/ARCCE-lfc -H &lt;CE hostname&gt; -x /etc/nagios/globus/userproxy.pem-ops'''''
Job finished successfully
 
Check the SRM:
 
'''''$ /usr/libexec/grid-monitoring/probes/org.ndgf/ARCCE-srm -H &lt;CE hostname&gt; -x /etc/nagios/globus/userproxy.pem-ops'''''
Job finished successfully
 
Before continuing, you may want to make sure that the probes for all services which the CE intends to offer, do actually succeed.
 
== SE checks  ==
 
check if gridftp server on SE works:
 
$ uberftp inaf-se-01.ct.pi2s2.it
 
For STORM SE: check if SRM client works (on the published information you can find the right port to use)
 
$ /opt/storm/srm-clients/bin/clientSRM ping -e httpg://sunstorm.cnaf.infn.it:8444
============================================================
Sending Ping request to: httpg://sunstorm.cnaf.infn.it:8444
============================================================
Request status:
  statusCode="SRM_SUCCESS"(0)
  explanation="SRM server successfully contacted"
============================================================
SRM Response:
  versionInfo="v2.2"
  otherInfo (size=2)
    [0] key="backend_type"
    [0] value="StoRM"
    [1] key="backend_version"
    [1] value="&lt;FE:1.5.0-1.sl4&gt;&lt;BE:1.5.3-4.sl4&gt;"
============================================================
 
<br> Try to write on SE. Be sure your UI is pointing to an IS the SE is contained in (you may use your certification BDII)
 
1) Setting a top-bdii that is publishing the SE you have to test
 
$ export LCG_GFAL_INFOSYS=&lt;TopBDII hostname&gt;:2170
 
2) Copy a file from the local filesystem to the SE, registering it in the LFC. This command output will return a SURL that you can use latter for other tests.
 
A SURL is a path of the type: srm://srm01.ncg.ingrid.pt/ibergrid/iber/generated/2011-02-01/file4034a935-8d7a-48f4-914f-16f2634d4802
 
$ lcg-cr -v --vo &lt;VO&gt; -d &lt;Your SE&gt; -l lfn:/grid/&lt;VO&gt;/test.txt file:&lt;/path/to/your/local/file&gt;
 
3) Create a new replica in other SE (to check the 3rd party transfer between 2 SEs)
 
$ lcg-rep -v --vo &lt;VO&gt; -d &lt;Other SE&gt; &lt;SURL&gt;
 
4) List Replicas
 
$ lcg-lr -v --vo &lt;VO&gt; lfn:/grid/&lt;VO&gt;/test.txt
 
5) Delete all replicas
 
$ lcg-del -v --vo &lt;VO&gt; -a &lt;guid&gt;
 
== Job submission  ==
 
Submit a test job to either '''lcg-CE''' or '''Cream-CE''' through the '''WMS''', i.e. using the '''glite-wms-job-submit''' command. In case, submit a mpi test job. The NGI_IT certification WMS is gridit-cert-wms.cnaf.infn.it
 
== Registration into 1st level HLR  ==
 
'''NOTE: this step is needed if your infrastructure uses DGAS as accounting system'''
 
After the site entered in production, it needs to register the site resources in the hlr. Ask the site-admins to open a ticket towards the hlr adminstrators, passing them the following information:
 
*grid queues names, in the form:
**gridit-ce-001.cnaf.infn.it:2119/jobmanager-lcgpbs-cert
 
*not-grid queues names, in the form:
**hostname:queue
 
*Name, surname ad certificate subject of each site-admin
*Certificate subject of Computing Element
 
Eventually, the site-admins have to open a ticket to DGAS support unit asking to enable the forwarding of accounting data from the 2° level hlr to APEL
 
== Certification Job  ==
 
The [[Cert Job|test job]] checks several things, like the environment on WN and installed rpms. Moreover it performs some replica management tests. With a "grep TEST" you may get a summary of the results: in case of errors, you have to see in detail what is gone wrong!
 
As already said, if the site supports any flavour of mpi, launch a mpi test job, like [[SiteCertMan/MPI Job Cert|this]]
 
don't forget to set a reasonable value in ''CPUNumber'': most important is that your job starts running quickly
 
If you want less stuff in the .out and .err files, in the file mpi-start-wrapper.sh comment the line
 
export I2G_MPI_START_DEBUG=1
 
A successful output will look like the following one (extract)
 
[...]
mpi-start [DEBUG  ]: using user supplied startup&nbsp;: '/opt/mpich-1.2.7p1/bin/mpirun '
mpi-start [DEBUG  ]: =&gt; MPI_SPECIFIC_PARAMS=
