END;/ 

2. 配置 cohere 认证

awk '/^--/{ next } { printf "%s", $0 } END { printf "\n" }' <your_private_key_file_path> | tr -d '\n'

sqlplus vector100/vector100@localhost:1521/orclpdb1

-- 初回の実行では必要なし
-- exec dbms_vector.drop_credential('OCI_CRED');
declarejo json_object_t;
begin-- create an OCI credentialjo := json_object_t();jo.put('user_ocid', 'user ocid value');jo.put('tenancy_ocid', 'tenancy ocid value');jo.put('compartment_ocid', 'compartment ocid value');jo.put('private_key', 'private key value');jo.put('fingerprint', 'fingerprint value');dbms_output.put_line(jo.to_string);dbms_vector.create_credential(credential_name => 'OCI_CRED',params          => json(jo.to_string));
end;
