Connect to Oracle Cloud by using wallets

Step 1. Unpack and move downloaded archives and files

1. Create a directory (for example, ~/Oracle/instantclient_19_8/).

2. Extract all packages to the created directory.

3. Move oraclepki.jar to the created directory.

4. Extract a ZIP archive with wallet files to the wallet directory inside the network directory. The path to wallet files might look as follows: ~/Oracle/instantclient_19_8/network/wallet.

   

Step 2. Add environment variables

This procedure is optional, but it might further simplify operations with OCI.

• Add the following environment variables:

Step 3. Configuring ORA files

note

For this step, you must have a ZIP archive with wallet files. For more details about downloading a wallet, see Download Client Credentials (Wallets) at docs.oracle.com.

An archive with wallet files includes tnsnames.ora and sqlnet.ora files.

1. In the directory that you created on Step 1, create the network directory. Inside the network directory, create the admin directory. The overall path should look as follows: ~/Oracle/instantclient_19_8/network/admin.

2. Copy tnsnames.ora and sqlnet.ora files to the admin directory.

3. Open the sqlnet.ora file from the admin directory in the text editor.

4. Change the value of the DIRECTORY attribute to the path to your wallet. For example, the path for this tutorial looks as follows:

   WALLET_LOCATION = (SOURCE = (METHOD = file)
   (METHOD_DATA = (DIRECTORY="/Users/jetbrains/Oracle/instantclient_19_8/network/wallet")))
   SSL_SERVER_DN_MATCH=yes

   Consider the following screenshot of the admin directory and configuration files.

   

Step 1. Prepare a driver for the OCI Cloud connection

1. In the Database tool window ( View | Tool Windows | Database), click the Data Source Properties icon .

2. In the Data Sources and Drivers dialog, click the Drivers tab.

3. In the list of drivers, right-click the Oracle driver and select Duplicate.

4. Change the name of the duplicated Oracle driver (for example, Oracle [Cloud]).

5. In the Driver Files pane, click the Add icon () and select Custom JARs….

6. In the file browser, navigate to the directory of the Instant Client that you created previously (for example, ~/Oracle/instantclient_19_8).

7. In the directory, select the following files: ojdbc8.jar, orai18n.jar, and oraclepki.jar.

8. Click Open.

9. In the Driver Files pane, click the Add icon () and select Native Library Path….

10. In the file browser, navigate to the directory of the Instant Client created previously (for example, ~/Oracle/instantclient_19_8) and click Open.

    

Step 2. Create the OCI connection

1. In the Database tool window ( View | Tool Windows | Database), click the Data Source Properties icon .

2. In the Data Sources and Drivers dialog, click the Add icon () and select Oracle.

3. From the Connection type list, select TNS.

   

4. From the Driver list, select OCI.

   

5. Click the Driver link and select the driver entry that you created on Step 1.

   

6. In the TNSADMIN field, click the browse button and navigate to the directory with the Instant Client (in our case, ~/Oracle/instantclient_19_8/).

7. In the TNS name field, specify what service name to use (see a value of an alias in tnsnames.ora).

8. Specify credentials for the Oracle user.

9. To ensure that the connection to the data source is successful, click the Test Connection link.

10. (Optional) If you are connecting to a data source that contains a lot of databases and schemas, in the Schemas tab, select the schemas that you need to work with.

11. Click OK to create the data source.
