Ocata Series Release Notes¶

15.1.3¶

In the Ocata release, Trove added support for encrypting the rpc communication between the guest DBaaS instances and the control plane. The default values for trove_taskmanager_rpc_encr_key and trove_inst_rpc_key_encr_key should be overridden to specify installation specific values.

New variables have been added to allow a deployer to customize a trove systemd unit file to their liking.

The task dropping the trove systemd unit files now uses the config_template action plugin allowing deployers access to customize the unit files as they see fit without having to load extra options into the defaults and polute the generic systemd unit file with jinja2 variables and conditionals.

For the os_trove role, the systemd unit TimeoutSec value which controls the time between sending a SIGTERM signal and a SIGKILL signal when stopping or restarting the service has been reduced from 300 seconds to 120 seconds. This provides 2 minutes for long-lived sessions to drain while preventing new ones from starting before a restart or a stop. The RestartSec value which controls the time between the service stop and start when restarting has been reduced from 150 seconds to 2 seconds to make the restart happen faster. These values can be adjusted by using the trove_*_init_config_overrides variables which use the config_template task to change template defaults.

The openstack service uri protocol variables were not being used to set the Trove specific uris. This resulted in ‘http’ always being used for the public, admin and internal uris even when ‘https’ was intended.

The variables trove_requirements_git_repo and trove_requirements_git_install_branch have been removed in favour of using the URL/path to the upper-constraints file using the variable pip_install_upper_constraints instead.
