# An improved index in the database table for OAuth clients

PingFederate 8.4 added the `value` column to an existing index (`IDX_FIELD_NAME`) in the `pingfederate_oauth_clients_ext` table as a general improvement.

This information is applicable only to customers who configured PingFederate to store OAuth clients on a database server.

You must modify the index in your existing `pingfederate_oauth_clients_ext` table.

Although there is no alter-table script provided, you can derive the setup from the new table-setup scripts in the `<pf_install>/pingfederate/server/default/conf/oauth-client-management/sql-scripts/oauth-client-management-<databaseServer>.sql` file.
