The following features/tools have been deprecated from this release and will be removed in future releases. Any self written scripts that utilise these features should be updated.

Command-line Tools (1)

  • tungsten_health_check and tungsten_provision_thl have been deprecated and will be removed in a future release
    Issue: CT-2506

Behavior Changes (7)

The following changes may affect existing scripts and integration tools. Any scripts or environment which make use of these tools should check and update for the new configuration:

Installation and Deployment (2)

  • tpm validate now verifies localhost is defined in /etc/hosts
    Issue: CT-2564

Command-line Tools (4)

    Issue: CT-2530

  • The tpm ask command now returns the appropriate values for keys: stagingdir,stagingpath, staginghost and staginguser.

    Additionally, the tpm ask staging command will return a JSON structure with all values. All values are the same as the output of the tpm query-staging command, just presented differently for easier machine usage.

    Issue: CT-2510

    Issue: CT-2451
  • The tungsten_send_diag command has been updated with new security keys and the ability to accept security keys on the CLI.
    Issue: CT-2438

Security (1)

  • As of version 7.2.0 onwards, when providing custom keystores, the alias of the mysql certificate must be provided as java-mysql-alias=xxx and must have the same name in both tungsten_keystore andtungsten_connector_keystore.
    Issue: CT-2598

Known Issue (1)

The following issues are known within this release but not considered critical, nor impact operation. They will be addressed in a subsequent patch release.

Security (1)

  • tungsten_mysql_ssl_setup incorrectly generates self-signed CA certificates on RHEL9 Linux flavors.

    This will be fixed in v7.2.0 and v8.0.1

    Issue: CT-2581

Improvements, new features and functionality (9)

Command-line Tools (5)

  • The tpm ask command will now convert values 0 and false toNo and values 1 and true to Yes as human output when given --human or -n cli args.
    Issue: CT-2559
  • The tpm ini command now handles all new tpm options.
    Issue: CT-2543
  • The tpm diag command now gathers the output of the tpm ini check -xcommand as the tpmINICheck call.
    Issue: CT-2499
  • The tpm cert command will now handle public key files. The command tpm cert gen public will create $CONTINUENT_HOME/generated/tungsten_public.jks from the$CONTINUENT_HOME/share/tungsten_keystore.jks file and thetpm cert list public command will show the contents, etc.
    Issue: CT-2434
  • The tpm ask command now supports the -s|--service option for dsrole, dsstate, trrole and trstate keys. The option alias for --short is now -S (capitalized), was previously lower-case. Example:
    tpm ask dsrole --service alpha
    Issue: CT-2400

Core Replicator (2)

  • The trepctl perf output has been improved when parallel apply is enabled to show granular statistics per channel.
    Issue: CT-2517
  • Replicator now recognizes the new MySQL 8.4 show binary log status syntax (as well as show master status) and will execute the configured replacement request appropriately.
    Issue: CT-2291

Security (1)

  • Tungsten can now hold two MySQL database SSL Certificates, allowing rotation of certificates without the need for downtime. A new command line tool, rotate_certs, is provided to aid in this process.
    Issue: CT-2511

Monitoring (1)

  • Additional prometheus metrics have been added to the Replicator:
    • tungsten_replicator_service_online_duration_seconds gauge show duration in seconds since the replicator was put online.
    • tungsten_replicator_task_total counter shows statistics by service, stage and task as shown in the following example:
      tungsten_replicator_task_total{service="alpha",stage="q-to-dbms",task_id="1",stat="extract_time",} 250.015
      In this case, this is the extract time spent by the task #1 of the q-to-dbms stage of the alpha service. This is similar to the new trepctl perf output.
    Issue: CT-2514
