Questions: will the rApps (2x) and the xApps (1 to 2x) be open-sourced where is the code for current rApps to inject the code into a sample rApp-frame? Please see: https://github.com/bmw-ece-ntust/nonrtric-rapp-energysaving/tree/master/ES%20rApp/src Please see: https://github.com/o-ran-sc/ric-app-rc can we have sample data for the AI Interface? can we share E2 sample data? to instruct UE to go to the remaining cell Reuse or create a topology for the use case 1x NonRtRic, 1x O-CU-UP 1x O-CU-CP, 2x O-DU, 4x O-RU (2 per O-DU) → 4 cells → 2 cells are just used from each O-DU ? - some UEs (not part of the topology) → one UE is sufficient for that use case maybe reuse: O-RAN-SC OAM Topology work needed on the report: https://hackmd.io/@q-eiMFW8TLa2Pa3QKECMzw/rkP1LlRyex request for documentation (rApp Manager) please look to the "sample rApp" with producers and consumers Updates 2025-05-07 by bimo fransiscus asisi - https://github.com/bmw-ece-ntust/smo-nearrt-autodep/tree/master/troubleshoot SMO installation - SMO ownerships and permission reinstall: wq should be re-install - please check if it is needed to be installed a root? resources allocation by the deployment CPU consumption by JAVA application root cause seems to be a no auth access to kafka issue understood be NonRtRic team - looking for a permanent fix SMO installation - AIMLFW idea of a common installation setup.sh improvement for Node port documentation - avoiding conflicts k8s version "mismatch" pick version: for k8s → strimzi → kafka - use installation script with option to selected use different k8s for AIMLFW and "rest of the SMO" async vs sync NBI of TEIV mainly read-only - SBI - may be never standardized - implementation currently event-based - no rest inf for writing data
