This allows reading the audio transcript and fast-forward to places in the video that are highly-relevant. The transcript usually take a few hours before available. The video is available immediately.
2. Regular items:
   
   1. Every time: Check that all L or XL commits of the last two weeks have also new unit tests. This is our policy. link-to-reviews (gerrit filter instructions // gerrit t-shirt-sizing).

4. RIC-671 (Alok) Who did originally pointed us to the “LF security” service? Which security issues it actually discovers that we do not already cover with Sonarcube? Does it actually address “container scans” for vulnerabilities? Does it cover scanning for including of vulnerable libraries or modules, like go modules? If we decide to go forward, we need to … (1) decide if we create a “meta project” entry similar to, e.g., CNCF? Like “O-RAN software community (O-RAN SC)” under which we then have separate projects, like, Near-RT RIC, which in turn will include a certain number of repositories?

   1. RIC-671 [Achieve level "passing" in CII] Requested Thoralf for submitting application for ORAN project onboarding on LFN security. // Also explored LFN inputs using nexus IQ. The example jobs failed into sandbox. Will continue to work on it.

10. RICAPP agenda: RICAPP Meetings.

2021-03-02

Recording:near_rt_ricplatform_and_ricapp_meeting_2021_03_02.mp4

1. Thoralf to figure out how to publish zoom recording
2. for CII compliance improvements we should do this from now on
   1. check that all large or XL commits of the last two weeks have also new unit tests. This is our policy. link-to-reviews (gerrit filter instructions // gerrit t-shirt-sizing).
   2. add a regular item in the meeting (once per month) to check code coverage
3. in context of CII, pls. note this convention in section "security bugs":  Tools (mailing list, JIRA, Gerrit)
4. Release criteria checklist template
5. If you raise issues to LF support that are sensible to make visible to others, pls. first raise a ticket to join "ORAN" organization in the support tool: "When these organizations (ORAN) were created in the beginning, we added by default all members from the committer groups into the organization. If at that time a particular user was not part of any group or just joined the community, then they will not be automatically added into the oran organization. Going forward, the new user will need to create a support ticket to be added to the organization."

6. HCL items:

   1. RIC-184 - [Adapt to latest K8S and helm (testing in OSC labs)] - InProgress VPN access enabled waiting for Felix to create VM in T-lab & share details. Sent the reminder on Thu (25th Feb). VM in T-lab still needed from Felix.

   2. RIC-723 - [Study performance overhead of latest opentracing solutions] – InProgress Able to generate sampling data after getting some help from thoralf. Continue to work with other scenarios to compare with previous results. sampling data now available. Numbers seem to be different than from previous PDF. Alok to schedule meeting with Thoralf once enough new information is available.

   3. RIC-731- [Static code and test coverage for E2] -  90% Completed. Had a debug session with E2 dev team today (2nd March) & we were able to get the blocker issue resolved. Looking forward to close the issue by this week & ready for submitting Gerrit changes to ci-management repo.

   5. RIC-150 - Perform e2e RIC benchmarking

      1. Subtask: RIC-741 Verify Subscription flow using RMR API Done – Still need to commit the code

   6. RIC-743 Create multiple e2sim for RIC benchmarking Able to connect 800 e2sim nodes to the ric platform. Number of connected nodes drops after trying to scale >800 (Tests fail with 1500 E2 node iterations).   

   7. RIC-744 Verify the E2E communication for multiple e2sim Transaction ID issue has been resolved. Now debugging the issue on subscription response messages with multiple e2simulator.

7. 1.5 slides from Rahul (if no time, by e-mail). Rahul to send mail. include Matti, Thoralf, Abukar, Alok. Ramesh, Sunil (if you don't have the address, I can add them to the mail later) → Slide E2APDesign 2.0.pptx
