2024-05-08 Meeting notes

• Migration to Java 17
  • Terms browser jenkins/Tomcat working
    • Issues with cart forwarding to http address
    • Excel export failing - possible POI conflict
      • What is the use case? Can we drop it
      • Large value sets are the issue and csv works.
      • Have pointer to FTP site?
      • examine use of this feature
  • CTS2 build/Jenkins working.
    • Tomcat has longstanding issues - hope to get VM tracker to debug - see below
• Will work on services one at a time on Dev and QA
  • Will send to new Stage and Prod
  • Will cutover when all finished
• Some of the value set files seem to want to live on local machine - compiledVSDefinitions?
  • • Do code review to determine where dependencies lie - create Jira item

Some conflict between teams doing hardware and software migrations.  Meeting this week.

Tomcat 9 is a priority, might need to sever from Java 17.

Security ticket - reported vulnerability disclosure issue and "hyperlinks".  We don't have access to the ticket or the security reports. 

Possibly could be the evs.cancer.gov/ftp1 - needs header and footer.

• Chasing ehcache temp bean jar creation
  • Normal behavior, but all files should be deleted when application shuts down/restarted
  • Claims files cant be used or processed - loading files fails. 
  • Kicks off at same time as commonValueSetsUtils. Does a hash of all value sets
  • ehcache updated as part of Spring 5 update
  • Heap Dump file might be useful during startup to see what is being loaded onto stack
    • onchange() no longer hooked up for managing process, since no longer loading during serving
    • Could be adding a lot of pressure on environment to build it all during startup
    • Could new OS be handling the stacks differently?
    • Corretto - outside chance this is an issue, but we think it not likely

• Requested Virtual VM - doesn't come automatially with Corretto
• Need to manage users to use x-forwarding
• Meeting with Cuong this week
• Examine what has changed in ehcache with Spring 5

• Still multiple issues on Prod
  • Scott creating Jira issues as items identified
• L3cache issues?  Possibly filling up and not allowing processing by cores
  • Dev has larger cache and more CPUs
• Possible security solution - throttle IPs that are overworking CPU
  • L5 load balancer

They have initiated tracking on this server. F5 Analytics has been enabled, will monitor to see what kind of data is produced.

• Results hopefully this week

• Prod completed testing
• Stage 2 - can we ask for top access to this?
• 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?
• List of EVS URLs

• Check with systems - See if we can test prod2 data deployment
  
• Start process for migrating DataQA to new server - Tracy

Brandon Devarra scanned DataQA and found it on Oracle Java 8.  Has it drifted from Prod?

-- 189356 (1) - OpenJDK 8 <= 8u392 / 11.0.0 <= 11.0.21 / 17.0.0 <= 17.0.9 / 21.0.0 <= 21.0.1 Multiple Vulnerabilities (2024-01-16

Path : /usr/local/jdk1.8/

Installed version : 8.0.391

Fixed version : Upgrade to a version greater than 8u392

Full DataQA needs to be migrated to new environment.  

• $PATH on devvm points to Oracle jdk.  Should be Corretto
• Chao to check with Mark tomorrow then look at creating ticket

• Check on JVM

Dev and QA not Corretto

• Type your task here, using "@" to assign to a user and "//" to select a due date
• Have systems check upper tiers
