Oracle wallet demo

This is a demo of the oracle wallet usage. You will find here examples in java, python and sqlplus. The wallet is a way to store encrypted login and password information. The wallet is generated and distributed by the DBA. On the client side you must configure

• An sqlnet.ora file that tells where the wallet lives.
• A tnsname.ora file that tells the ip and service name of the database. The test database in this example is called WDEMO2_TESTING.
• A copy of the wallet directory that stores the credentials.

Pre requirements

It assumes that the oracle instant client, pip and java are installed. Ask your local DBA to create a wallet for you. You should also might want to copy a running wallet on a tns directory. You can use the container to have everything you need, except the wallet.

Configuration

Edit tns/tnsnames.ora to match your database ip and service. Generate the wallet files and copy them to tns/wallet.

Java

In order to use wallet you must add to this code the following jars:

• ojdbc8.jar
• oraclepki.jar
• osdt_cert.jar
• osdt_core.jar

They are downloaded via maven so you must have it first. You can also find them here.

Invoking the wallet on java is done by using 'jdbc:oracle:thin:/@TESTWALLET'

Environment variables

You can add a TNS_ADMIN file to tell where the tnsnames is.

Invoking a wallet enabled configuration

In this case there is a single user on the wallet. In python you invoke the wallet config by using the dsn TESTWALLET. In sqlplus you must use /@TESTWALLET

Build and run the container

docker build -t walletcontainer .

docker run -it walletcontainer:latest /bin/bash

Builiding this

Run make all. This is done on the container build.

Running this

On the container, execute

make run-java

make run-python

make run-sqlplus

Look at the Makefile to see how it was executed.
