Training Slides: Advanced 303: Upgrading from Tungsten Clustering 5.x Multi-Site/Multi-Master to 6.0 Multi-Master
- 1. Advanced : Upgrading from v5.x Multi-Master to v6 Multi-Master
- 2. Topics In this course we will: • Review the key difference between v5 and v6 • Discuss new Service Names • Walkthrough an Upgrade (Full end to end demo) Course Prerequisite Learning – Basics: Introduction to Clustering – Advanced: Multisite/multi-master Tungsten Clustering deployments for geo-distributed apps – Visit Continuent website or Tungsten University on YouTube to watch these recordings 2
- 4. Upgrade Checklist • Upgrade to v5.3 first if you are on an older release • Review the release notes – https://docs.continuent.com/tungsten-clustering-6.0/release-notes.html • Obtain the latest package for Tungsten Clustering – Tungsten Replicator no longer needed for Multi-Master! • Backup Backup Backup • Test Test Test! • Convert to an ini Install • Watch this video a few times and review the documented steps – https://docs.continuent.com/tungsten-clustering-6.0/deployment-multimaster-clustering-upgrade-from-v5.html • You don’t have to do it alone, we want to, and will, help you! 4
- 5. New Service Names • Installation will automatically configure and create the cross-site replication services • Cluster service name set in the configuration • Example – Cluster 1 service name = NYC – Cluster 2 service name = LONDON – Cross site service names created as follows: • On NYC nodes: – nyc – Cluster service name and local replication service – nyc_from_london – Service for replication from the LONDON service • On the LONDON nodes – london – Cluster service name and local replication service – london_from_nyc - Service for replication from the NYC service 5
- 8. Tools : cctrl 8 • “cctrl” can be run from any node within ANY cluster to control either cluster and gather information • Move between clusters by issuing cd /<service> • Type “help” to get a full list of all commands available • “ls” provides a summary overview of the entire cluster
- 9. Tools : trepctl 9 • “trepctl services” lists a summary of all services on a given node • “trepctl –service <servicename> status” can be run from any node within a cluster to view the status of the replicator specific to that node • “trepctl –service <servicename> status –r 3” will show status output refreshed every 3 second until CTRL+C • “trepctl –service <servicename> qs” provides a quick summary overview of the local replicator • “trepctl –service <servicename> perf” provides deeper diagnostics of the different stages in the replicators
- 10. Log Files 10 • The /opt/continuent/service_logs/ directory contains both text files and symbolic links. • Links in the service_logs directory go to one of three (3) subdirectories: – /opt/continuent/tungsten/tungsten-connector/log/ – /opt/continuent/tungsten/tungsten-manager/log/ – /opt/continuent/tungsten/tungsten-replicator/log/ • <component>-user.log files are less verbose • More detailed logs are within relevant component log directory tungsten@db1:/opt/continuent/service_logs $ ll total 116 lrwxrwxrwx 1 tungsten tungsten 61 Mar 2 09:52 connector-user.log -> /opt/continuent/tungsten/tungsten-connector/log/connector-user.log lrwxrwxrwx 1 tungsten tungsten 55 Mar 2 09:52 manager-user.log -> /opt/continuent/tungsten/tungsten-manager/log/manager-user.log lrwxrwxrwx 1 tungsten tungsten 60 Mar 2 09:52 replicator-user.log -> /opt/continuent/tungsten/tungsten-replicator/log/replicator-user.log
