What's New

Every new patch or patch set release of TimesTen 22.1 may include new features or functionalities that are documented in this guide. These new features or functionalities are listed below and provide links into the guide for more information.

New features in Release 22.1.1.17.0

  • Previously, you could only provide credentials when opening a connection to the TimesTen database by providing the user name and password individually using connection attributes. Now, you can specify user credentials within an Oracle Wallet where the wallet location is provided when opening a connection. The preferred method of specifying a user name and password is by storing both in an Oracle Wallet.

    See Creating a Connectable File.

  • Previously, you could only provide cache administration user credentials by providing the cache administration user name and both of its passwords to the TimesTen and Oracle databases individually using connection attributes. Now, you can specify cache administration user credentials within an Oracle Wallet where the wallet location is provided when opening a connection. The preferred method of specifying the cache administration user name and both passwords is by storing them in an Oracle Wallet.

    See Create a Connectable for the TimesTen Database.

  • You must register the Oracle database cache administration user name and password internally in the TimesTen database before any cache group operation can be issued. Before you register the Oracle cache administration user and password internally within the TimesTen database, you must decide if you want to save these credentials in an Oracle Wallet (recommended) or within memory (the default). To save the credentials within an Oracle Wallet, ensure that the CacheAdminWallet connection attribute is set to 1 (likely in your DSN). This directs that the registration of the Oracle cache administration user name and password are stored in an Oracle Wallet.

    See Register the Cache Administration User Name and Password in the TimesTen Database and Create a Database Definition for the TimesTen Database.
