Configuration parameters by functionality v14
This section provides more detail for certain groups of configuration parameters.
The section heading for each parameter is followed by a list of attributes:
- Parameter ype. Type of values the parameter can accept. See Setting configuration parameters section for a discussion of parameter type values.
- Default Value. Default setting if a value is not explicitly set in the configuration file.
- Range. Permitted range of values.
- Minimum scope of effect. Smallest scope for which a distinct setting can be made. Generally, the minimal scope of a distinct setting is either the entire
cluster(the setting is the same for all databases and sessions thereof, in the cluster), or
per session(the setting may vary by role, database, or individual session). (This attribute has the same meaning as the
Scope of Effectcolumn in the table of Summary of Configuration Parameters).
When Value Changes Take Effect.Least invasive action required to activate a change to a parameter’s value. All parameter setting changes made in the configuration file can be put into effect with a restart of the database server; however certain parameters require a database server
restart. Some parameter setting changes can be put into effect with a
reloadof the configuration file without stopping the database server. Finally, other parameter setting changes can be put into effect with some client side action whose result is
immediate. (This attribute has the same meaning as the
When Takes Effectcolumn in the table of Summary of Configuration Parameters).
Required Authorization to Activate.The type of user authorization to activate a change to a parameter’s setting. If a database server restart or a configuration file reload is required, then the user must be a EPAS service account (
postgresdepending upon the EDB Postgres Advanced Server compatibility installation mode). (This attribute has the same meaning as the
Authorized Usercolumn in the table of Summary of Configuration Parameters).
