Configuration Group Management for DB2
|
||||
=======================================
|
||||
|
||||
This spec talks about how to enable configuration group management
|
||||
for DB2.
|
||||
|
||||
Launchpad Blueprint:
|
||||
https://blueprints.launchpad.net/trove/+spec/db2-config-group
|
||||
|
||||
|
||||
Problem Description
|
||||
===================
|
||||
|
||||
Trove supports configuration group management but this feature has not been
|
||||
implemented for DB2.
|
||||
|
||||
|
||||
Proposed Change
|
||||
===============
|
||||
|
||||
DB2 supports both database manager configuration parameters and database
|
||||
configuration parameters. The database manager configuration parameters
|
||||
apply to an instance whereas the database configuration parameter applies
|
||||
to each database. In this spec, we talk about implementing configuration
|
||||
management for the DB2 database manager.
|
||||
|
||||
The database manager configuration parameters are stored in the db2systm file
|
||||
under the sqllib directory. To update the configuration parameters, DB2
|
||||
recommends using the UPDATE DBM CONFIGURATION and RESET DBM CONFIGURATION
|
||||
commands instead of directly updating the config file. To see a complete list
|
||||
of configuration parameters, check the Appendix section.

|

-----------
|
||||
|
||||
Implement update_overrides and apply_overrides in the manager and service
|
||||
modules.
|
||||
|
||||
The following files will be updated::
|
||||
|
||||
/opt/stack/trove/trove/guestagent/datastore/experimental/db2/manager.py
|
||||
/opt/stack/trove/trove/guestagent/datastore/experimental/db2/service.py
|
||||
/opt/stack/trove/trove/guestagent/datastore/experimental/db2/system.py
|
||||
|
||||
The following file will be added::
|
||||
|
||||
/opt/stack/trove/trove/templates/db2/validation-rules.json
|
||||
|
||||
This will fit into the existing configuration manager framework. The existing
|
||||
'PropertiesCodec' implementation will be reused to handle text-file operations.
|
||||
Configuration overrides will be implemented using the 'ImportStrategy' of the
|
||||
guestagent configuration manager.
