Oracle Wallet is used to store configuration information for secure connections to Oracle databases.
Datical DB supports Liquibase Enterprise supports secure connections (SSL) to Oracle databases through Oracle Wallet. This page describes the process:
- Have the correct version of the Oracle JDBC driver installed. The driver supplied with Datical DB with Liquibase Enterprise versions 5.7.5665 (or higher) was updated to support Oracle Wallet.
- Set up required configuration files and environment variables.

Datical DB uses Liquibase Enterprise uses Oracle Wallet for certificates only. You specify a user and password for the connection separately when creating the connection to the database in each DbDef. |
See Oracle Wallet documentation maintained by Oracle Corporation.

You cannot use the Datical Accelerator for Oracle in projects or DbDefs where you are using Oracle Wallet for secure connections. (Note that the optional accelerator/compression driver was only available with versions 7.15 or lower. It has been deprecated for versions 7.16 and higher.) See Datical Accelerator for Oracle (deprecated).
Prerequisite: Oracle Wallet Installed and Configured
...
Create a directory on the host where you run Datical DB run Liquibase Enterprise to use for the wallet file and Oracle configuration files.
The example places it in the oracle_wallet directory under the <project> directory in the default location for Datical DB for Liquibase Enterprise projects. If Oracle is installed on the host, another common location might be $ORACLE_HOME/network/admin.

)
) |
3. Set TNS_ADMIN to Point to the Configuration Files Directory
On the host where Datical DB where Liquibase Enterprise is running, set the TNS_ADMIN environment variable to the directory containing the configuration files.
