1. JDBC System Properties
The following describes JDBC system properties.
-
jeus.jdbc.connection-pool.initialization-on-boot
Description
Option to initialize JDBC connection pools in the server during the server startup.
-
true: Initializes JDBC connection pools during the server startup.
-
false: Initializes JDBC connection pools when a service is first requested. (Default)
Default
false
-
-
jeus.jdbc.connection-pool.keep-initialization-on-connection-error
Description
Option to complete the initialization of connection pools even if an error occurs when a JDBC connection is created.
-
true: If an error occurs while creating a JDBC connection during the initialization of connection pools, the initialization process is finalized with the connection pool in an empty state, and the connection pool is separately managed as a failed status. (Default)
-
false: If an error occurs while creating a JDBC connection during the initialization of connection pools, the initialization process is marked as a failure.
Default
true
-
-
jeus.jdbc.monitoring.active-connection-number-recording-buffer
Description
"Active Average" in JDBC monitoring values is the average of the recent counts of active connections during a specified time.
This option enables the display of average active connection counts based on data accumulated within a defined time frame. By default, a time period of 3600 seconds (one hour) is applied, and the average active connection counts for the past one hour are shown as "Active Average".
Default
3600 (Unit: second)
-
jeus.jdbc.monitoring.active-connection-number-recording-period
Description
"Active Average" in JDBC monitoring values is the average of the recent counts of active connections during a specified time.
This option determines the frequency at which active connection counts are checked in the background to accumulate data. By default, 5 seconds is applied, meaning that active counts are recorded every 5 seconds. These accumulated counts are then used to calculate and display the average as "Active Average".
Default
5 (Unit: second)
-
jeus.jdbc.config.data-source-account-provider-class-name
Description
Name of the entire class that implements the customization of DB access account management. The class must implement the jeus.jdbc.helper.DataSourceAccountProvider interface. For more information, refer to DataSourceAccountProvider Interface in JEUS Server Guide.
If not specified, JEUS uses the default implementation that links with JEUS Security.
Default
null
-
jeus.jdbc.xa-check
Description
Checks whether XAResource#start is possible before performing a check query during the validation process.
Default
false
