Default Query Timeout (Seconds) |
|
|
|
| NON_NEGATIVE_INTEGER | |
| 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. | |
|
|
60
|
|
|
|
|
Max Idle Connections |
|
|
|
| NON_NEGATIVE_INTEGER | |
| The maximum number of idle connections to keep in the database connection pool at any given time. | |
|
|
8
|
|
|
|
|
Connection Max Lifetime (millis) |
|
|
|
| POSITIVE_INTEGER | |
| 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. Minimum recommended value: 120000 | |
|
|
| (no default) | |
|
|
|
Max Total Connections |
|
|
|
| POSITIVE_INTEGER | |
| 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. | |
|
|
8
|
|
|
|
|
Max Wait (Seconds) |
|
|
|
| POSITIVE_INTEGER | |
| The maximum number of seconds that a request should wait for a database connection before timing out and aborting. | |
|
|
30
|
|
|
|
|
Min Idle Connections |
|
|
|
| NON_NEGATIVE_INTEGER | |
| The minimum number of idle connections to keep in the database connection pool at any given time. | |
|
|
0
|
|

|
Pool Prepared Statements |
|
|
|
| BOOLEAN | |
| 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. | |
|
|
false
|
|
|
|
|
Database Type |
|
|
|
| ENUM | |
| Values |
|
|
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.
|
|
|
|
| (no default) | |
|
|
|
Expect database to be writable |
|
|
|
| BOOLEAN | |
| Fail health-check if the database is read-only. | |
|
|
false
|
|
|
|
|
Database Password |
|
|
|
| PASSWORD | |
| Password for the persistence database. | |
|
|
| (no default) | |
|
|
|
Database Update Mode |
|
|
|
| ENUM | |
| Values |
|
| 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. | |
|
|
UPDATE
|
|
|
|
|

|
|
| ENUM | |
