Deferred Maintenance lets customers configure maintenance-disabled windows of up to 90 days to avoid downtime during business-critical periods, while zero-downtime security patches continue to apply. Maintenance Events provide an immutable log recording when maintenance occurred, its type, duration, and success, supporting auditing and governance. Both features can be configured and inspected via the OCI Console, CLI, or SDK. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How long can I configure a maintenance-disabled window for MySQL HeatWave on OCI? Maintenance-disabled windows can be configured for up to 90 days, since MySQL requires regular maintenance and there must be no more than 90 days between the last downtime-imposing maintenance before the window and the first one after it ends. During this window, only zero-downtime maintenance such as security patches will be applied, and instances remain online and accessible. _Teams scheduling database maintenance around business hours can track platform changes like this on daily.dev._ ### What information does MySQL HeatWave log for each maintenance event? MySQL HeatWave now logs when maintenance started and completed, the MySQL versions before and after, whether it was manually or automatically triggered, whether it affected the database, OS, or hardware, or was zero-downtime, and whether it succeeded. A planned enhancement will add exact downtime or switchover time for highly available systems. _Database engineers auditing maintenance history can follow updates like this on daily.dev._ ### Can I configure MySQL HeatWave maintenance settings using the OCI CLI instead of the console? Yes, maintenance-disabled windows and maintenance events can be configured and inspected using the OCI Console, the OCI CLI, or any OCI SDK. In the console, you enable the maintenance-disabled window and specify start date, start time, end date, and end time in UTC, while events appear under the Maintenance tab. _Ops teams automating cloud database management can track tooling changes like this on daily.dev._ ## Similar posts on daily.dev - [Automating MySQL HeatWave Maintenance with the OCI Command Line Interface \(CLI\)](https://daily.dev/posts/automating-mysql-heatwave-maintenance-with-the-oci-command-line-interface-cli--byukeenos) · Planet MySQL · 0 upvotes · 0 comments - [Enabling OCI Log Analytics for MySQL HeatWave – Now available for MySQL 8.4](https://daily.dev/posts/enabling-oci-log-analytics-for-mysql-heatwave-now-available-for-mysql-8-4-d2ya7bhpc) · Planet MySQL · 0 upvotes · 0 comments - [Amazon RDS Custom for SQL Server adds ability to view and schedule new operating system updates](https://daily.dev/posts/amazon-rds-custom-for-sql-server-adds-ability-to-view-and-schedule-new-operating-system-updates-vl6golxbk) · AWS · 0 upvotes · 0 comments - [Take Control of Your Native App Upgrades with Maintenance Policies](https://daily.dev/posts/take-control-of-your-native-app-upgrades-with-maintenance-policies-gvllzveya) · Snowflake Community · 0 upvotes · 0 comments - [Data Daz \(dasini.net\) – Data Systems, AI, and Real-World Insights](https://daily.dev/posts/data-daz-dasini-net-data-systems-ai-and-real-world-insights-wypxekwjz) · Planet MySQL · 0 upvotes · 0 comments --- Tags: [#database](https://daily.dev/tags/database), [#mysql](https://daily.dev/tags/mysql), [#oracle](https://daily.dev/tags/oracle) [View this post on daily.dev](https://daily.dev/posts/more-control-more-visibility-deferred-maintenance-events-in-mysql-heatwave-zjejrogqb) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"More Control, More Visibility: Deferred Maintenance & Events in MySQL HeatWave","url":"https://daily.dev/posts/more-control-more-visibility-deferred-maintenance-events-in-mysql-heatwave-zjejrogqb","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/more-control-more-visibility-deferred-maintenance-events-in-mysql-heatwave-zjejrogqb"},"datePublished":"2026-08-14T18:43:42.763Z","dateModified":"2026-09-13T19:31:58.780Z","description":"MySQL HeatWave on OCI introduces Deferred Maintenance and Maintenance Events features.
