Updating configuration table settings
Last updated: 9/17/2026You can edit properties manually in the configuration.properties file.
To add a comment in the configuration file, you need to add a new line above the
parameter, and start with #. For example:
#lower the value
hibernate.c3p0.max_size=120| Configuration property | Description | Default/min/max value |
|---|---|---|
| db.alert.enabled | Enable email alerts for database connection status changes. Talend Administration Center sends one email when the database connection becomes unreachable and one recovery email when the database connection is restored. Configure SMTP before you enable this property. | Default value is false. |
| db.alert.recipients | Define the recipients for database alert emails. Specify one or more email addresses separated by semicolons. | No default value. |
| scheduler.conf.startupResumeBatchSize | Number of blocked triggers processed in each batch when they are resumed during Talend Administration Center startup when scheduler.conf.restartTriggersDuringAppStart is set to true | Default value is 50. Set to 0 to process all blocked triggers in a single batch, restoring the previous behavior and increasing the load on database connections during startup. |
| scheduler.conf.startupResumeBatchDelayMs | Delay, in milliseconds, between batches when blocked triggers are resumed during Talend Administration Center startup when scheduler.conf.restartTriggersDuringAppStart is set to true. This delay allows database connections to be released before the next batch starts. | Default value is 5000. Set to 0 to disable the delay, which can increase the load on database connections during startup. |
| softwareupdate.nexus.repositoryID | Set the repository ID to fetch the patch lists. | N/A |
| artifact.repo.actions.retry.delay | Set the interval of retry attempts for the Artifact Repository actions if the artifact.repo.actions.retry.attempts parameter is enabled. | Default value is 5000. |
| artifact.repo.actions.retry.attempts | Set the count of retry attempts for the Artifact Repository actions, such as getting checksum or downloading an artifact. | Default value is 0 (disabled). |
| server.project.auto.auth | Grant any project access when creating a new Job server or virtual server. | Default value is true. |
| random.jobserver.selector | Change the virtual server selection behavior in cluster mode. When this property is set to true, Talend Administration Center selects a random available server in the virtual server and deploys the Job only on that server. If the Job is already deployed on one server, that server remains preferred for execution. | Default value is false. When false, the default rating-based selection behavior is used. |
| repository.connection.timeout | Set the timeout for establishing a connection to Nexus, Nexus 3, or Artifactory. | Default value is 30000 milliseconds. |
| repository.response.timeout | Set the timeout for waiting for the HTTP response from Nexus, Nexus 3, or Artifactory after the connection is established. This property is independent of repository.connection.timeout. | Default value is 30000 milliseconds. |
| blocked.paths | Set blocked paths. |
This parameter is disabled by default. /etc/, /proc/, /dev/, /root/, /lib/, /boot/, /sys/ and c:/windows/ are blocked for log and license paths by default. To change the blocked paths, uncomment the parameter, specify values and restart Talend Administration Center. |
| environment.name environment.name.color |
Show the environment name in Talend Administration Center UI header. |
These parameters are disabled by default. If the value of environment.name.color is not in the HEX format, it will be ignored and the environment name will be displayed in white. PROD and #FF0000 are examples for environment.name and environment.name.color. |
| use.local.job.when.download.failed.from.artifact.repository | Reuse locally cached Jobs if the Artifactory (Nexus 2/Nexus 3/Artifact) is down to run successfully tasks. | Default value is false. |
| scheduler.conf.restartTriggersDuringAppStart | Pause and resume triggers automatically when Talend Administration Center restarts | Default value is false. |
| artifact.statistics.fromJobInfo | Enable or disable statistics from jobInfo.properties file | Default value is true. |
| remoteconnection.project.enableLocks | Enable the addLocks and removeLocks MetaServlet commands in Talend Administration Center. You can use this property for compatibility with older Talend Studio versions that still rely on lock APIs. When this property is set to false, these commands return HTTP 405. | Default value is false. |
| userPassword.minLength | Minimum password length | Default value is 10. |
| userPassword.maxLength | Maximum password length | Default value is 128. |
| scheduler.conf.taskStatusRefreshTime | Number of seconds between each task status refresh | Default value is 5 seconds. |
| scheduler.conf.maxConcurrentTaskDeployment | Maximum number of concurrent tasks that can be deployed in parallel | Default value is 10. |
| scheduler.conf.uiAutoRefreshFrequency | Number of seconds for refresh interval value when enabling auto refresh | Default values are 360 seconds for Execute Plan page and 10 seconds for other pages. |
| scheduler.conf.retryRestartTaskWhenConnectionServerFailed.enable | Enable to retry the restart of task when server connection failed | Default value is false. |
| configuration.module.hide | Hide the configuration menu | Default value is false. |
| dashboard.conf.taskExecutionsHistory.detailsInfoPopup.uiAutoRefreshSec | Number of seconds for refresh interval value for task execution panel | Default value is 10 seconds. |
| scheduler.conf.defaultTimeoutOnUnknowJobServerState | Number of seconds set for timeout on unknown task status from Job Server. | Default value is 120 seconds. |
| scheduler.conf.uiFineAutoRefresh | Enable auto refresh for UI | Default value is true. |
| sso.signature.key.name | Defines the key identifier type used to sign the SAML logout request sent by Talend Administration Center. | Default value is NONE. Supported values are NONE and KEY_ID. |
| sso.signature.key.path | Specifies the path to the private key used to sign the SAML logout request. | This property is empty by default. |
| sso.signature.certificate.path | Specifies the path to the certificate associated with the private key used to sign the SAML logout request. | This property is empty by default. |
| sso.signature.algorithm | Specifies the signature algorithm used to sign the SAML logout request. | Default value is http://www.w3.org/2001/04/xmldsig-more#rsa-sha256. Supported values are http://www.w3.org/2001/04/xmldsig-more#rsa-sha256, http://www.w3.org/2001/04/xmldsig-more#rsa-sha384, and http://www.w3.org/2001/04/xmldsig-more#rsa-sha512. |
