You can modify a shard's ECPU count, auto-scaling setting, and storage allocation.

You can modify shards in a Globally Distributed Autonomous AI Database from its Details page.

1. Go to the Details page of the Globally Distributed Autonomous AI Database in which you want to modify a shard.
2. In the Details page, on the Shards and Catalog tab, select Modify from the Actions (three dots) menu for the shard you want to make changes to.

   On the Modify Shard pane you can configure the ECPU and storage settings.

   • ECPU - The number of ECPU cores to enable. Specify the number of ECPUs for the shard as an integer. Available cores are subject to your tenancy’s service limits.

   • ECPU auto scaling - Enable automatic scaling based on workload per shard/shardspace.

   • Storage - GB of storage to allocate to your shard.

   • Data Guard - Indicates if an Oracle Data Guard standby instance is deployed for this shard.
3. Click Apply to save the changes to the shard.
