2. Main Achievements
Repository: Ran the production repository with no internal problems this quarter. There was one scheduled firewall outage of 45 minutes at RAL and a few very small network breaks which prevented the service receiving new data. This data would all have been received the next time the affected clients tried to publish. Total availability 99.97%.
Heavier support load than usual. Mainly due to rollout of CREAM CE and configuration errors during setup. It would be good to have second line support for APEL as for the other middleware. The APEL Team should only be providing third line support.
The planned production release of the new infrastructure slipped beyond the end of this quarter.
There is a test repository running all the time to receive tests from other sites developing their software against SSM the new STOMP and Python-based messaging layer which runs on the production EGI Messaging Infrastructure. All of the other existing and new accounting services have tested using SSM except SGAS where the developer has moved on and has not yet been replaced.
3. Issues and Mitigation
|Issue Description||Mitigation Description|
|SL4-5 migration requires all APEL servers to be down together for several days.||Downtime announced well in advance. Primed TPM to respond to sites who post tickets having missed the broadcast.|
4. Plans for the next period
Start a production service receiving summaries from other accounting services over SSM and joining them with the old summary system. Once all systems have migrated the old database will be migrated to a new one and the old clients piped into that. This second step is likely to be in Q8.
