deployment API test plan
by Steve Loughran 04 Aug '05

04 Aug '05

Hello all, This is the draft of the test plan for deployment. One area that crops up is 'how to test that deployments work'; I think we need to design a few test components that should be implemented on all systems that want to support our communal test suite; ones that will have consistent behaviour across platforms/implementations and be used to test behaviour. For example we could have a failure component that could be configured to fail on initialisation, or on liveness, perhaps dependent on the value of some boolean attribute. We can then test configurations that trigger failures, conditional failures, failures on liveness checks, etc. The other useful one is something that can assert that two values are equal; then we can deploy configurations with various assertions in there, such as early and late binding paths. Only if resolution works according to the specifications will the assertion tests pass, so only then will deployment succeed. the original is under SCM at http://cvs.sourceforge.net/viewcvs.py/*checkout*/deployment/deployment/doc/… any generated test files will go into SCM there. I will NOT be sending any of the test files out over the mail list; if you want the files, you have to check them out from the repository, anonymously or with an account.

Hi Jun, The foundation document where we describe use cases belongs to GGF, not to us. However, it is publicly available, so I see no reason why they can not refer to this document or use it as a starting point for their use cases. As far as re-using our own material, I have nothing against it, however I am cc-ing Hiro and John who are our technical area directors and may have more information about the details and appropriateness. Thanks, Dejan. > -----Original Message----- > From: Jun Tatemura [mailto:tatemura@sv.nec-labs.com] > Sent: Wednesday, August 03, 2005 9:05 AM > To: Milojicic, Dejan S > Cc: cddlm-wg(a)ggf.org > Subject: Re: [cddlm] Notes of the meeting on 8/3/2005 > > Hi Dejan and Team, > > I am sorry I was absent because I was confused with Today's > meeting with OGSA... > > I wanted to ask if we can give some Grid deployment use cases > to OASIS SDD TC (they are now aggregating use cases to > identify requirements).

Notes from the OGSA EMS & CDDLM meeting
by Milojicic, Dejan S 03 Aug '05

03 Aug '05

By phone, 8/3, 2pm-3pm PST. Attendees: Mark Morgan, Hiro Kishimoto, Chris Smith, Stuart Schaefer, Jun Tatemura, Ravi Subramanian, Mike Behrens, Steve Loughran, and Dejan Milojicic. Notes taker: Dejan Milojicic. Agenda: 1. Go over the two documents (CDDLM Foundation document for EMS people an the OGSA architecture document for the CDDLM people. Dejan suggested that CDDLM is part of the EMS, but there are other pieces which are out of scope. Chris asked about activity v. solution. The answer was that we support solutions not activities. Hiro: can we also support C code, Cobol, etc. The answer is yes, but we need to support the environments. Ravi: we need to resolve the terms between the two groups prior to the meeting. Hiro: there is a glossary document. Good suggestion (Dejan), that way we can get consistent independently. It is linked off of https://forge.gridforum.org/projects/ogsa-wg/docman/draft-ggf-ogsa-spec/ en/23. Ravi: There is a space for provisioning in the EMS document, we try to plug in the CDDLM as a virtual exercise. We try to effectively see if CDDLM is compatible with OGSA. Chris, there are issues with containers. Chris: extending JSDL (extensions) with CDDLM or embedding the schemas. Steve: it is batch -centric. Chris: it is not really. Ravi: keep provisioning separate from JSDL. Dejan: summary, this is a good proposal, but for simplicity reasons, we'll keep it out of our immediate objectives for the time being. 2. Agenda for F2F (8/16, 1:30-5 in Sunnyvale): Action preparation for the meeting: sync up with glossary (Ravi: also check up the glossary if we have any comments). A) (1:30-1:45) Introduction (learn more about EMS broader picture, in the past wee overviewed CDDLM) B) (1:45-3:15) Defining architectural relationship (This is really related to the pictures we discussed above, Fig 5 in the OGSA arch & Fig 7 in CDDLM Foundation) C) (3:15-3:45) Indebt overview of the CDDLM interfaces (if needed) D) (3:45-4:15) Description and integration of ACS & CDDLM (Ravi: added BES as well). E) (4:15-4:45) Integration roadmap F) (4:45-5:00) Next steps (Dejan: above times are approximate, they may change as needed, e.g. if we cover some of the later items in earlier sessions) Ravi: is this similar to BES interfaces activities. Chris: this was exactly how I was thinking wrt BES container. We can jump ahead to conclusion that CDDLM also created container. it is definitely in the context of BES cause we will run through the BES and we will automatically se how it fits with BES. The same applies to RSF. It is almost looking through a use case how do we do with something that is given to job provisioning. Hiro: There is one more important component, ACS. Dejan/Steve, we came to some agreement with ACS at GGF 14 and there is no need for changes to CDDLM wrt ACS. Hiro: ACS had a F2F meeting in North Carolina. Mike prepared a document describing relationship between CDDLM and ACS. Ravi: we can add the ACS diagram to the figure. (as well as BES), this way we can tackle multiple birds at the same time. Mike: ACS has taken requirements wrt contents, there are some security considerations and creation time issues that would require something other than URL, maybe service invocation, we can go over these details at F2F. 3. Techniques and expectations: Dejan: informal approach, discussions, drawing pictures, agreeing on interfaces, it is ok to have a few more open issues, but resolve them at latest at GGF15. Ravi: can someone bring digital camera, take a snapshot and then send it, put it on Webex. Hiro: expects architectural diagram and text describing components, so that they can come into the next version of architectural document. Ravi: when is the time (Hiro: 1:30-5pm)

Hi, I was asked for the URL for the OGSA architecture document. It is linked off of: https://forge.gridforum.org/projects/ogsa-wg/docman/ EMS related pieces are on page 17-26. Thanks, Dejan.
