28.16Database

The Database configuration category includes the following configurable options:

Database Type
Database Connection URL
Database Username
Database Password
Database Update Mode
Min Idle Connections
Max Idle Connections
Max Total Connections
Connection Max Lifetime (millis)
Max Wait (Seconds)
Default Query Timeout (Seconds)

28.16.1Property: Database Type

Property Name	Database Type
Property Key
Property Type	ENUM
Values	`H2_EMBEDDED` `DERBY_EMBEDDED` `MARIADB_10_1` `MYSQL_5_7` `POSTGRES_9_4` `ORACLE_12C` `MSSQL_2012`
Description	The database platform being used. Smile CDR supports several relational database platforms for persistence so this setting selects the dialect that is specific to the platform being used. For example, if you are using Postgres 9.4, select the `POSTGRES_9_4` dialect.
Default Value	(no default)
Example Property	`module.[MODULE_ID].config.db.driver =`

28.16.2Property: Database Connection URL

Property Name	Database Connection URL
Property Key
Property Type	STRING
Description	JDBC Connection URL for the persistence database. The following examples show JDBC URLs for a few different database platforms: Derby Filesystem: `jdbc:derby:directory:target/testDatabase;create=true` Postgresql: `jdbc:postgresql://localhost/cdr` MariaDB: `jdbc:mariadb://localhost:3306/cdr`
Default Value	(no default)
Example Property	`module.[MODULE_ID].config.db.url =`

28.16.3Property: Database Username

Property Name	Database Username
Property Key
Property Type	STRING
Description	Username for the persistence database.
Default Value	(no default)
Example Property	`module.[MODULE_ID].config.db.username =`

28.16.4Property: Database Password

Property Name	Database Password
Property Key
Property Type	PASSWORD
Description	Password for the persistence database.
Default Value	(no default)
Example Property	`module.[MODULE_ID].config.db.password =`

28.16.5Property: Database Update Mode

Property Name	Database Update Mode
Property Key
Property Type	ENUM
Values	`UPDATE` `NONE`
Description	Controls whether Smile CDR should attempt to update the FHIR storage database schema on startup. If the database schema is out of date, Smile CDR automatically run migration on the FHIR storage schema at startup if the value is "UPDATE" If the value is "NONE", then Smile CDR will abort starting the FHIR storage module if its schema is out of date. When set to "NONE", you should use the "smileutil migrate" command to upgrade the database manually.
Default Value	`UPDATE`
Example Property	`module.[MODULE_ID].config.db.schema_update_mode = UPDATE`

28.16.6Property: Min Idle Connections

Property Name	Min Idle Connections
Property Key
Property Type	NON_NEGATIVE_INTEGER
Description	The minimum number of idle connections to keep in the database connection pool at any given time.
Default Value	`0`
Example Property	`module.[MODULE_ID].config.db.connectionpool.minidle = 0`

28.16.7Property: Max Idle Connections

Property Name	Max Idle Connections
Property Key
Property Type	NON_NEGATIVE_INTEGER
Description	The maximum number of idle connections to keep in the database connection pool at any given time.
Default Value	`8`
Example Property	`module.[MODULE_ID].config.db.connectionpool.maxidle = 8`

28.16.8Property: Max Total Connections

Property Name	Max Total Connections
Property Key
Property Type	POSITIVE_INTEGER
Description	The maximum total number of connections to allow the database connection pool to hold at any given time. Set this value carefully as it may negatively impact database performance when set too low or too high.
Default Value	`8`
Example Property	`module.[MODULE_ID].config.db.connectionpool.maxtotal = 8`

28.16.9Property: Connection Max Lifetime (millis)

Property Name	Connection Max Lifetime (millis)
Property Key
Property Type	POSITIVE_INTEGER
Description	If set, provides the maximum total number of milliseconds that a connection is allowed to live. Any connections that are open for longer will be closed instead of being reused. Note that this setting applies only to idle connections in the pool, it does not affect active database operations even if the timeout is exceeded.
Default Value	(no default)
Example Property	`module.[MODULE_ID].config.db.connectionpool.maxlifetime.millis =`

28.16.10Property: Max Wait (Seconds)

Property Name	Max Wait (Seconds)
Property Key
Property Type	POSITIVE_INTEGER
Description	The maximum number of seconds that a request should wait for a database connection before timing out and aborting.
Default Value	`30`
Example Property	`module.[MODULE_ID].config.db.connectionpool.maxwait_seconds = 30`

28.16.11Property: Default Query Timeout (Seconds)

Property Name	Default Query Timeout (Seconds)
Property Key
Property Type	NON_NEGATIVE_INTEGER
Description	This setting is the maximum number of seconds that a query may run before being automatically aborted by the database. This setting is a failsafe to prevent overly taxing searches from dominating the database.
Default Value	`60`
Example Property	`module.[MODULE_ID].config.db.connectionpool.default_query_timeout_seconds = 60`

28.16.12Property: Pool Prepared Statements

Property Name	Pool Prepared Statements
Property Key
Property Type	BOOLEAN
Description	If enabled, prepared statements will be pooled by the connection pool. Note that when using schema-based multitenancy, Smile CDR may choose to ignore this setting.
Default Value	`false`
Example Property	`module.[MODULE_ID].config.db.connectionpool.pool_prepared_statements = false`

28.16.13Property: SQL Parameter Bind Mode

Property Name	SQL Parameter Bind Mode
Property Key
Property Type	ENUM
Values	`ALWAYS_INLINE` `INLINE_NUMERIC` `NEVER_INLINE`
Description	Specifies whether parameters in SQL statements should be inlined or bound to parameters.
Default Value	`NEVER_INLINE`
Example Property	`module.[MODULE_ID].config.db.sql_parameter_bind_mode = NEVER_INLINE`
