Notes from the meeting

Agenda Item 1. "Generalised Attributes"

We agreed on this name for a new attribute that was mentioned so far with various names like: This request was discussed at the 2006-03-17 workshop, during the meeting with the VO Managers, presented by Joel Closier (LHCb VO-Admin). We had agreed that he would submit a document to explain the details. Unfortunately, this was not minuted so the necessary development effort was never coordinated within the TF.

This experience shows that a twiki page listing all requirements is necessary. The CNAF guys will do this and send the URL to the whole TF. All TF members will be authorised to edit that page. ACTION 1: Andrea/Vincenzo(Done)

Each developer implementing any of these requirements will open the necessary savannah tickets and link them from/to the twiki page. Savannah is still our tool for detailed progress follow-up and inclusion in the gLite release.

Tanya checking Vincenzo's presentation at the EGEE06 conference pointed out -and Vincenzo confirmed- that the Generalised Attribute value can represent something different for every VO/user. She expressed concern about the vagueness of this attribute's definition and management.

Everybody agreed that both vomrs and voms-admin have customers in various Grid projects (EGEE, LCG, OSG, others). These customers are, sometimes, not only the VOs but also other VOMS-aware services.

Ruth said that Generalised Attributes seem to be meant for application management and not for registration management. We should, therefore, probably re-evaluate the possibility to use a single interface (voms-admin) to manage them.

The consensus at the end of the discussion was:

Agenda Item 2. CA rollover

A person with 2 certificates (same DN/different CAs) is one record in the vomrs database.
A person with 2 certificates (regradless of DN,CA) is two entries in the voms database.
The CNAF guys will document how they intend to proceed with the handling of this. ACTION 4: Andrea/Vincenzo/Valerio

Agenda Item 3. Oracle

The voms-admin and vomrs development effort was discussed to use multiple listeners and OCI connections to the Oracle database. The discussion was based on the summary table and the importance to coordinate with the gLite integrator Joachim Flammer was underlined. Andrea can make a OCI option available soon ACTION 5: Andrea but Joachim has to parse the option in the glite-voms-server-configuration script ACTION 5: Joachim. Tanya will also change the vomrs_configure script to give the installer the option for 'oci' or 'thin' connection ACTION 5: Tanya Progress will be monitored via savannah bug #19654.

Agenda Item 4. tomcat

The situation is monitored via savannah bug #16843. As no test system showed the problem we experience on the production servers, we 'll install jdk1.5 and closely observe tomcat memory usage while at CERN in the week of Jan.22nd 2007. ACTION 6: Developers and Maria.
About the claimed wrong tomcat packaging in glite Joachim should be reminded to comment. ACTION 7: Developers and Maria.
The idea to start the apache server and use it as a re-director to a number of tomcat processes to load-balance the handling of the ssl sessions should be elaborated in the ticket. ACTION 8: Andrea

Agenda item 5. January VOM(R)S workshop agenda

The draft agenda was accepted with the additions of Ruth's suggestions and the recommendation to involve the Integration Team for the Oracle OCI discussion. Maria has already invited testers and integrators who have booked their agendas. She will split the agenda items throughout that week in the indico system. ACTION 9: Maria (Done)

Agenda item 6. AOB

Maria stressed the importance of bug voms-ping bug which has already led us to service failures. The voms core developers are working on it and will comment in savannah. ACTION 10: Vincenzo/Valerio
