Adding Shards

Add shards to scale out your Globally Distributed Database.

You can add shards when:

• You have completed Creating a Globally Distributed Exadata Database on Exascale Infrastructure Resource, but have not yet completed Deploying Globally Distributed Exadata Database on Exascale Infrastructure.

• You have completed Deploying Globally Distributed Exadata Database on Exascale Infrastructure and want to scale up your Globally Distributed Exadata Database on Exascale Infrastructure (Distributed ExaDB-XS) with more shards.

To add shards:

1. On the Globally Distributed Exadata Database on Exascale Infrastructure list page select a Distributed ExaDB-XS.

2. On the details page, under Shards, select Add Shard.

3. On the Add shard pane configure the new shard.

   • Shard count: enter the number of shards you want to add.

     You can add up to 10 shards in each set to deploy, and then add more after deployment if needed.

   • Shard: Shows the display name for each shard or shardspace in the configuration. Once you select a region the name is populated.

   • Region: Select the region where you would like to host the shard.

   • VM cluster: Select a cluster available in the selected region.

   Note: It is recommended that you use one VM cluster per database (shard or catalog).

4. In Create administrator credentials, set the password for the shard database ADMIN user.

5. Select the Encryption key details for the new shards.

   Select the compartment, vault, and master encryption key that were configured in Configure Security Resources.

6. Select Validate to run checks to make sure the new shards are valid.

7. After any validation errors are addressed and validation is successful, select Add Shards to deploy the new shards.

   Note: There is a time limit for deploying new shards.

   • When scaling up a deployed Distributed ExaDB-XS, you must complete Deploying Globally Distributed Exadata Database on Exascale Infrastructure within 7 days of completing this procedure or you will get an error and must terminate the new shard resources and start again.

   • When adding shards to an undeployed Distributed ExaDB-XS, you have 7 days from completing Creating a Globally Distributed Exadata Database on Exascale Infrastructure Resource to add any shards and complete Deploying Globally Distributed Exadata Database on Exascale Infrastructure.
