Step 9. Configure the Elastic Server

Step 9. Configure the
Elastic Server

In Administrator, configure the service properties for the

Elastic Server

.

The following image shows the

Elastic Server

properties:

When you view or edit a Secure Agent and select the Elastic Server as the service, the Elastic Server properties appear in the System Configuration Details area. The service type is set to All Types, and the PARAMFILE, LOG4J, AWS, AZURE, and CONCURRENCY properties are displayed.

You can configure the following

Elastic Server

properties:

Type	Name	Description
PARAMFILE_CFG	parameterfile_access_flag	Indicates whether developers can download parameter files that are stored on the Secure Agent machine. Default is 'true.'
PARAMFILE_CFG	parameterfile_access_directory	List of directories on the Secure Agent machine that allow parameter file download. Developers can download parameter files from any of the specified directories or subdirectories. Default is '/$AGENT_HOME/apps/data/userparameters, /$AGENT_HOME/apps/Data_Integration_Server/data/userparameters.'
LOG4J_CFG	log4j_app_log_level	Level of detail that the Elastic Server writes to log files. Enter the logging level as a string, such as 'INFO.' As the logging level increases, the messages that the Elastic Server writes to log files include the messages in the prior logging levels. For example, if the logging level is INFO, the log contains FATAL, ERROR, WARNING, and INFO code messages. The following values are valid: FATAL. Includes nonrecoverable system failures that cause the service to shut down or become unavailable. ERROR. Includes connection failures, failures to save or retrieve metadata, and service errors. WARNING. Includes recoverable system failures or warnings. INFO. Includes system and service change messages. TRACE. Logs user request failures. DEBUG. Logs user request logs.
AWS_CFG	agent_role_external_id_key	External ID that the Secure Agent specifies when the agent attempts to assume the cluster operator role. Required if you configure an external ID in the trust relationship of the cluster operator role. This property takes effect only in an AWS environment.
AWS_CFG	privileged_role_arn_key	ARN of the cluster operator role. Required when you set up separate cluster operator and Secure Agent roles in an AWS environment. This property takes effect only in an AWS environment.
AWS_CFG	role_session_duration_secs_key	Session duration of the AWS AssumeRole API in seconds. By default, the session duration is 1800 seconds (30 minutes). Overrides the maximum CLI/API session duration that is configured for the cluster operator role. If the session duration configured for the Elastic Server is longer than session duration for the cluster operator role, the Secure Agent might fail to assume the cluster operator role. This property takes effect only in an AWS environment.
AZURE_CFG	azure_agent_role_identity_client_id	Client ID of the managed identity agent_identity . Required when agent_identity is a user-assigned managed identity and the Secure Agent machine has at least one other managed identity. This property takes effect only in an Azure environment.
CONCURRENCY_CFG	allow_queuing	Indicates whether the Elastic Server queues Spark tasks. Default is true.
CONCURRENCY_CFG	max_concurrent_jobs	Maximum number of concurrent Spark tasks that the Elastic Server can process.
