Feature Overview
Configuration management supports modifying key parameters of TCBase, allowing service configuration adjustments based on actual needs. This document describes how to configure TCBase service parameters via the console.
Operation Steps
Editing Configuration Items
1. Log in to the EMR Serverless TCBase console, select the corresponding instance in the instance list, and click Instance ID/Name to go to the instance details page. 2. Go to the configuration management page. If you want to search for a specific configuration item or narrow down the search range of configuration items, you can filter them using the filter on the left.
3. Select the configuration file as needed, click Edit Configuration to enter the editing mode, and perform operations such as editing or deleting configuration items as required.
Select the parameter to be modified and enter a new value. If needed, click Restore to restore to the original value, or click Default Value to restore the system-recommended default value.
Some parameters support deletion. To delete this configuration, choose Delete > Confirm.
4. After confirming the changes, click Save Configuration. Once the configurations are distributed and the service is restarted successfully, the modification of configuration items is complete.
Importing Configurations in Batches
1. Log in to the EMR Serverless TCBase console, select the corresponding instance in the instance list, and click Instance ID/Name to go to the instance details page. 2. Go to the configuration management page. If you need to modify configuration items in batches, click Edit Configuration to enter the editing mode, and select Import Configuration to perform batch import. The configuration files supported for import are as follows:
Managed configuration files: Only supports importing specific configuration files already managed in the console, specifically including configuration files in .xml, .properties, .conf, .config, .cfg, and .sh formats.
Exported configuration: Supports importing JSON-formatted .conf configuration files exported via the Export Configuration feature on the configuration management page.
Note:
When a naming conflict occurs between an imported second-category .conf configuration file and an imported first-category .conf configuration file, the system will prioritize parsing according to the format of the first-category configuration file. This may cause parsing issues for the second-category configuration file. Proceed with caution to avoid unnecessary errors.
Exporting Configurations
1. Log in to the EMR Serverless TCBase console, select the corresponding instance in the instance list, and click Instance ID/Name to go to the instance details page. 2. Go to the configuration management page and click Export Configuration.
3. Select the files to be exported and the export scope, and click Export Configuration to download the software configuration files to your local machine.
3.1 Export Mode: Defaults to All configurations, and supports selecting to export only customized or modified configurations (choose one).
3.2 Export Format: Only the JSON format is supported.
