• Migration to Java 17
  • Tomcat update required?
  • Browser impact? Would like to work on NCI Terms Browser
  • xerces and other XML libraries now incorporated into Java17. Need to remove duplicates
  • JPA structures might be impacted
• Spring 6 is part of Java 17 migration
• Evaluating lucene and need to update

Who owns the Terms Browser at this point? 

• Two parties on same code base
• Contractural requirements constraining responsibilities? Per Mark it is OK
  •  Mark will talk to Lori, with warning from Jason

• Changes we have made included making more objects, but the volume should not have changed
• Caches should be saved for 600 seconds
• Unclear if it is resource bound - whether it is possible to build a big enough server
• Would be good to do profiling under load - on a lower server.
• Also having issues with lack of database connections - increasing max connections might help?

• Massive queries - bot related
• Attempt being made at CIT level to block - more local blocking unsuccessful
• Lucene errors seen on Mappings queries
  • index readers clashing. 
• Issues have been elevated over the last few months.

Meeting on Friday, Jan 5, at 1PM. Some conflicts so might need reschedule

• Have increased connections to database in lbconfig.props? Need to restart
• Would suggest using maintenance page each time browser is restarted, rather than allowing user contact
• Blue/Green deployment scheme still should be considered
  • New Prod server is physical
  • Database would need to replicated blue/green as well
  • Current deployment script is 'complex' and written generations ago.
• Chao suggested looking at the caching and making that more efficient
  • Browser startup has increased to ~30 minutes, up from 10-15.
  • Per Scott that slowness is not seen on Dev
  • Per Chao DataQA does not have that problem 
• Stage and Prod seem to be logging aggressively, which is resource consuming

•  Create Jira to examine logging on Stage and Prod - compare to lower tiers
•  Send Mark URL to update plans
  • How to do data deployments
  • How to migrate to new servers

•  Set up load testing against Terms Browser and lexevs on Dev tier
  •  Install load testing/monitor on Dev
•  Replicate query test package against EvS Explore/EVS Rest as a compare

• Prod to begin next week - will be full server
  • Have begun configuring the back end
  • Meet with Eric to discuss the server capacity issues above?
• DataQA after Prod
  • database on machine - migrate first?
  • Test performance of old loaders vs new database.
  • Other apps follow DB - determine if needs to be co-located
  • Does script need to be updated?

• Any migration issues or impact? Lyubov concerned about management. Requested guidelines of use.
• Need to make sure Mark and Jason have admin privileges
  • Need to have WebEx with Lyubov and set up admin team and add members
• No privileges to NCIP so may not be able to merge back in there anymore
• Any impact on levevs GitHub? Not urgent

•  Mark and Jason need to meet with Lyubov to determine user privileges .

Released?

Gilberto asked us to publish a non-versioned copy of the inferred NCIt.  Any issues?

Chao back next week so can discuss it then
