Upgrade dSource

Upgrades

Periodically Production and Lower environments are upgraded for various reasons like

  • To be in compliance
  • To mitigate bugs
  • Security concerns
  • To meet compatibility with other software.

Upgrading the Source database to a higher version will impact dSource snapsyncs if the version upgarded is not compatible with version of staging database. Delphix can handle the upgrade of the databases by updating the configuration in dSource.

Upgrade dSource to a higher version.

  • Step 1: Install the same version of Cassandra software on the staging host.[ same version as source ].
  • Step 2: Refresh Environment in Delphix hosting Staging dSource.
  • Step 3: Verify the new Cassandra Binaries are discovered in the environment with entry [DataStax Cassandra - (version: x.x.x) ].
  • Step 4: Disable dSource [ Manage Datasets → Select dSource → disable ].
  • Step 5: Log in to Delphix engine via CLI (ssh) interface and execute the following commands. 
cd sourceconfig  
select <dSource_Name>  
update  
set repository = <New Cassandra Binaries discovered in Step 3 >  
commit;
  • Step 7: Enable dSource [ Manage Datasets → Select dSource → disable ]
  • Step 8: Take a new snapshot to validate that snapsync works as expected.
