1. Open the GCP Console and navigate to the Spanner instance that needs to be remediated.
2. Click on the instance name to open the instance details.
3. Under the “Instance Configuration” section, click on “Edit”.
4. In the “Edit Instance Configuration” window, scroll down to the “High Availability” section.
5. Select the “Regional” option to enable regional availability for the Spanner instance.
6. Choose the desired region for the Spanner instance from the drop-down menu.
7. Click on “Save” to apply the changes.
8. Once the changes are saved, the Spanner instance will be highly available across the selected region.

​

1. Open the Cloud Shell in the GCP console.
2. Run the following command to check the current configuration of Spanner Database:
   Copy

   Ask AI

   gcloud spanner instances describe [INSTANCE_NAME] --project=[PROJECT_ID]
   

   Replace [INSTANCE_NAME] with the name of the Spanner Database instance and [PROJECT_ID] with the ID of the GCP project.
3. Check the value of the availabilityConfig field in the output of the above command. If the value is REGIONAL, then the instance is highly available. If the value is ZONAL, then the instance is not highly available.
4. To make the instance highly available, run the following command:
   Copy

   Ask AI

   gcloud spanner instances update [INSTANCE_NAME] --project=[PROJECT_ID] --availability-type=REGIONAL
   

   Replace [INSTANCE_NAME] with the name of the Spanner Database instance and [PROJECT_ID] with the ID of the GCP project.
5. After running the above command, the instance will be updated to be highly available. You can check the configuration again by running the command in step 2.

1. Check the current configuration of the Spanner Database:

from google.cloud import spanner

# Create a Spanner client object.
spanner_client = spanner.Client()

# Get a reference to the instance.
instance = spanner_client.instance('your-instance-id')

# Get a reference to the database.
database = instance.database('your-database-id')

# Check if the database is highly available.
if database.is_highly_available():
    print('The database is highly available.')
else:
    print('The database is not highly available.')

2. If the database is not highly available, update the configuration to make it highly available:

from google.cloud import spanner

# Create a Spanner client object.
spanner_client = spanner.Client()

# Get a reference to the instance.
instance = spanner_client.instance('your-instance-id')

# Get a reference to the database.
database = instance.database('your-database-id')

# Update the configuration to make the database highly available.
database.update_ha(enable=True)

# Check if the database is now highly available.
if database.is_highly_available():
    print('The database is now highly available.')
else:
    print('The database is still not highly available.')

3. Verify that the database is now highly available by checking the database configuration:

from google.cloud import spanner

# Create a Spanner client object.
spanner_client = spanner.Client()

# Get a reference to the instance.
instance = spanner_client.instance('your-instance-id')

# Get a reference to the database.
database = instance.database('your-database-id')

# Check if the database is highly available.
if database.is_highly_available():
    print('The database is highly available.')
else:
    print('The database is not highly available.')
