# Setting up Redis external attribute caching with dsconfig

## Before you begin

When using the `dsconfig set-policy-decision-service-prop` command, the new configuration must still be compliant with the following:

* The `pdp-mode` property must be set to `embedded`.

* The `deployment-package-source-type` property must be set to `store` or `static-file`.

  * If the `deployment-package-source-type` property is set to `store`, the `deployment-package-store` property must resolve to a valid deployment package store.

  * If the `deployment-package-source-type` property is set to `static-file`, the `deployment-package-store` property must resolve to a valid deployment package.

## About this task

Here are the configuration options available for creating Redis external caches using the `dsconfig` tool. When using the `dsconfig create-external-attribute-cache` command, the new configuration must still be compliant with the required attributes associated with the specified cache type:

| Option               | Description                                                                                                                                  |
| -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------- |
| `mode`               | Required. Specifies Redis mode. Accepted values: `single_instance`, `replicated`, `elasticache`, or `sentinel`.                              |
| `nodeAddresses`      | Required, only when `mode` is `single_instance`, `replicated`, or `sentinel`. Defines node addresses. A comma-separated list of Redis nodes. |
| `replicationGroupId` | Required, only when `mode` is `elasticache`. Replication group ID.                                                                           |
| `masterName`         | Required, only when `mode` is `sentinel`. Specifies name of the master node.                                                                 |
| `database`           | Optional, only when `mode` is `sentinel`. Database index used for Redis connection. Default value is `0`.                                    |
| `scanInterval`       | Optional, only when `mode` is `sentinel`. Redis cluster scan interval in milliseconds. Default value is `1000`.                              |
| `checkSentinelList`  | Optional, only when `mode` is `sentinel`. Enables Sentinels list check during startup. Default value is `false`.                             |
| `username`           | Optional, only when AUTH token authentication is enabled in the Redis provider.                                                              |
| `password`           | Optional, only when AUTH token authentication is enabled in the Redis provider.                                                              |

## Steps

1. Create the external attribute cache using the `dsconfig create-external-attribute-cache` command. For example:

   ### Example:

   ```shell
   $ dsconfig create-external-attribute-cache \
     --cache-name 'Single Instance' \
     --type redis-single-instance \
     --set redis-node-addresses:redis://localhost:6379
   ```

2. Assign the defined external attribute cache to the Policy Decision Service. For example:

   ### Example:

   ```shell
   $ dsconfig set-policy-decision-service-prop \
     --set 'external-attribute-cache:Single Instance'
   ```

## Result

Your external attribute cache has been defined and attached to the Policy Decision Service. There is no need to restart the server.
