"
- Several ROCs complained about the problematic release last week. Reply (Release managers and pre-production teams): We apologise for the disruption caused. Update20 was accelerated due to requirements coming from CCRC08. The installation issue with the CE was due to a mistake in the release preparation, because the dependency of the installation function from the new version of yaim-core version was not correctly set. Of course, as the correct version of yaim-core was already deployed in pre-production (but not in production) this issue was not visible for the pre-deployment testers in PPS. This particular issue could only have been trapped by a deployment test in production (currently not foreseen by the release procedure). BTW: yaim-core was being held back in PPS because it forced a change in the permissions schema for the site-info.def and containing directory to be implemented at all sites, which was not rated acceptable for the operations.
The issue found later on in production affecting the submission from CE3.0 to WN3.1 has another explanation. CE at version 3.1 has been in production for more than two months, which means that regression tests are not being done in certification. Pre-production run, by mandate, the top version of the services
- DPM 3.0 is no longer supported. Therefore no regression testing is done on services for this release.
- Configuration of SGE for short jobs
- The old Edinburgh site, ce.epcc.ed.ac.uk will be retired from use in one week time (1 May 2008). We should once again send a broadcast to the VOs about this - just in case!
