FTS news
- FTS 2.2.8 EMI now running in production at: CERN on all the FTS servers (pilot, T2Export and T0Export), NDGF-T1, RAL-LCG2, Taiwan-LCG2, FZK-LCG2 (just yesterday, waiting confirmation everything is ok). Rollout to the T1s is ongoing.
- Summary of 2.2.8 rollout - https://svnweb.cern.ch/trac/glitefts/wiki/FTS228RolloutPlanning
- Detailed FTS server deployment plan: https://docs.google.com/spreadsheet/ccc?key=0AthhzXLQok7XdFpUeDBfLXE2S1RDZE4zcHp6QWVpUFE .
- Alessandro from CNAF requested to postpone their date for FTS upgrade towards the end of the required period 28-29.3. Ale confirmed that 4 hrs max. are enough.
- CMS (Nicolo) said 3 GGUS tickets were opened with FTS 2.2.8 experience recently. The new functionality of 'resume' transfers requires a patch, now ready and being tested on the pilot system in order to use a less frequent check-point (now checking every second and overloading the system). The new EMI release in April will contain this patch.

- Experiment reports:
- ALICE: Testing the use of Active Data Guard in order to replace Streams PVSS replication.
- ATLAS: new schema ATLAS_CONF_TRIGGER_MC added to replication from CERN to Tier1 sites. ATLAS LFC replication to BNL being investigated.
- CMS: Move to Active Data Guard (to replace Streams replication) is progressing. Streams apply handler errors due to changes in Oracle 11g.
- Active Data Guard monitoring being improved.
- Site reports:
| Site | Status, recent changes, incidents, ... | Planned interventions |
|---|---|---|
| BNL | ntr | None |
| CNAF | ||
| KIT | Migrated the Compass-LFC schema to the new hardware (FTS-cluster) and upgraded this cluster to 11.2.0.3. The migration and upgrade process to 11g is finished at KIT/Gridka. Some problems with communication between FTS-frontend and FTS-DB observed. Probably related to SCAN-IP or SERVICE_NAME request. Working on it. | None |
| IN2P3 | Follow-up on upgrade issues with Oracle. | Upgrade to 11g eventually next week - being agreed with experiments |
| PIC | ntr | None |
| RAL | Follow-up on scan listener issues with Oracle, bug doc 1379498.1. Data Guard configuration running for CASTOR databases. | None |
| SARA | ||
| TRIUMF | Compatible parameter updated to 11.2.0.3 | None |
