+# Oracle
+
+In this example, we will show how to use the Oracle as in DB-GPT Datasource. Using Oracle to implement Datasource can, to some extent, alleviate the uncertainty and interpretability issues brought about by vector database retrieval.
+
+### Install Dependencies
+
+First, you need to install the `dbgpt oracle datasource` library.
+
+```bash
+
+uv sync --all-packages \
+--extra "base" \
+--extra "datasource_oracle" \
+--extra "rag" \
+--extra "storage_chromadb" \
+--extra "dbgpts"
+```
+
+### Prepare Oracle
+
+Prepare Oracle database service, reference-[Oracle Installation](https://docs.oracle.com/en/database/oracle/oracle-database/index.html).
+
+Then run the following command to start the webserver:
+```bash
+
+uv run dbgpt start webserver --config configs/dbgpt-proxy-openai.toml
+```
+
+Optionally, you can also use the following command to start the webserver:
+```bash
+
+uv run python packages/dbgpt-app/src/dbgpt_app/dbgpt_server.py --config configs/dbgpt-proxy-openai.toml
+```
