Method of creating new meeting notes pages

Just noticing that JIRA links are being copied to new meeting notes pages as literal text, rather than as Confluence widgets. So they are no longer showing the current status of the JIRA case, e.g. see "Container sizing" item below with AAI-1940. It was initially "open", but as of now, it should be "closed".

Suggest that new meeting notes pages should be created using the Confluence "Copy page" menu item, as this will preserve the widgets in the page. Note that the "Copy page" menu item will also copy attachments, such as video recordings, so these would need to be deleted afterwards.

  •  James Forsyth will clean up old closed items and fix copied Jira links on next week's meeting notes.

/ Orchestration Scenarios

From Me to Everyone: 03:03 AM
points 1f and 2f, any tool having access to ONAP API can push inventory data into AAI, is there more to it than that?
From RRAO to Everyone: 03:04 AM
Does it have to follow any specific Network Model like T-API ?
From Me to Everyone: 03:05 AM
AAI does have its own schema, so maybe some translation would be required
From RRAO to Me: (Privately) 03:06 AM
We are planning to orchestrate L0/L1 service so will touch base with you via email.

From Me to RRAO: (Privately) 03:06 AM

Need to maintain these for Dublin, and expand to include things like MSB integration. Establish a working group to develop CSIT test cases for Dublin and document them on the wiki. James Forsyth will create the page and solicit ideas.

Tomcat-embed license policy

org.apache.tomcat.embed in springboot 1.5.18 has a strong copyleft license. Can we exclude this from the package since we don't use the embedded tomcat? James Forsyth has shown that this mitigates the issue in the resources project

Helm Chart OwnershipJames Forsyth

OOM is planning to make a new repo for our OOM helm charts and give us the ability to commit changes. The community is still working out process of how these updates will be merged into the public repos that all teams use. We need to look at our team's ability to support this, including having a test process internally to validate changes before we merge them.

7th Jan: could this

9Casablanca Maintenance Release

The casablanca branch is open for CMR code reviews. Discuss what will be included in the CMR.

Release artifacts need to be available 10 Jan 2019

James Forsyth send note to OOM team to see which branch they are accepting changes for CMR - Update: according to Mike Elliot CMR changes go to the OOM 'casablanca' branch and master is open for Dublin updates.

Lab support

To assist with monitoring JIRA, suggest subscribing to this filter: https://jira.onap.org/issues/?filter=11532, which does pick up AAI-1913 - AAI queries not working in SB-06 Open as discussed. Also sent a message to onap-discuss to ask if JIRA Notification Scheme and new email list could be setup as well.

There is a document which shows us as delivering the history backend in Casablanca - need to discuss if we are providing an accurate picture of what's available in Casablanca.

Hbase to Cassandra migration

Bell Canada has a requirement to migrate their A&AI Graph DB backend from HBase to Cassandra.

We are enabling this effort.


We have been investigating GraphAdmin code in ONAP, which seems to support the framework.

We would like to make enhancements to this framework and contribute to ONAP.


The initial enhancements we would like to accomplish are:

  • Provide option to the end-user to select FROM and TO Version
    • The current code doesn’t have this option
  • Support schema migration to V14
    • Current support exists for V11->V13

Our goals:

  • AAI backend upgrade from HBase to Cassandra (V11 to V14)
  • Seamless upgrade and rollback of AAI DB

The main issue is that it is not clear how to get started - Francis Paquette will look at what's on the readthedocs site, I think we need to port what Keong has put in the wiki to the main docs repo at a minimum.

24Support for 2 OOM deployment types

Motivation: Decrease the resource footprint for A&AI (ONAP) deployments

Idea: we could support 2 different deployments 1. full (normal) deployment and 2. barebones deployment. The point of the "barebone" deployment would be to deploy only the essential services necessary for proper functioning of A&AI (leaving out services like cacher, sparky, graphadmin, having 1 cassandra node instead of 3 or 5 etc).

In order to reduce hardware/cloud costs (mainly the memory footprint) it could be beneficial to support a minimalistic A&AI deployment.

5G PNF Software upgrade

We have a 5G related functionality in Change management, 5G PNF Software upgrade. https://wiki.onap.org/display/DW/5G+-+PNF+Software+Upgrade

Right now, PNF software version is modeled and accepted in SDC, and also approved in Modeling subcommittee and TSC.https://wiki.onap.org/display/DW/TSC+2018-07-26+Meeting+Agenda. (Modeling report)

We are not familiar with A&AI. The target of this functionality is to  update PNF Sw version when upgrade completion with specified pnfid. Could you and your team give us some help on this?

1)      Is there any available  APIs provided by AAI for this? 

2)      If yes, can you give me some details on it. If not, could you and AAI team provide support in Casablanca? We would like to provide contributions if needed.
