+Connection pool
+---------------

+.. versionadded:: 5.2
+
+To use a connection pool with `oracledb`_, set ``"pool"`` to ``True`` in the
+:setting:`OPTIONS` part of your database configuration. This uses the driver's
+`create_pool()`_ default values::
+
+    DATABASES = {
+        "default": {
+            "ENGINE": "django.db.backends.oracle",
+            # ...
+            "OPTIONS": {
+                "pool": True,
+            },
+        },
+    }
+
+To pass custom parameters to the driver's `create_pool()`_  function, you can
+alternatively set ``"pool"`` to be a dict::
+
+    DATABASES = {
+        "default": {
+            "ENGINE": "django.db.backends.oracle",
+            # ...
