Database Connections with Wallet Location Directories Containing Parenthesis Not Supported

The DIRECTORY setting in the WALLET_LOCATION parameter does not support values that contain parenthesis characters for Exadata Express connections. WALLET_LOCATION is set in the profile configuration file sqlnet.ora. This restriction applies only to OCI-based drivers, such as unmanaged ODP.NET and JDBC Type 2.

For example, the following generates an error due to the parenthesis characters in the directory location:

WALLET_LOCATION=(SOURCE=(METHOD=file)
       (METHOD_DATA=(DIRECTORY="C:\Program Files (x86)\Oracle")))

Workaround

Use the Windows 8.3 file name convention to reference directories containing parenthesis. For example, "C:\PROGRA~2\Oracle" can be substituted for "C:\Program Files (x86)\Oracle" because it uses the 8.3 file name convention:

WALLET_LOCATION=(SOURCE=(METHOD=file)
       (METHOD_DATA=(DIRECTORY="C:\PROGRA~2\Oracle")))

Microsoft Certificate Stores Not Supported

Microsoft Certificate Stores (MCS) are repositories for storing digital certificates and their associated properties. Exadata Express does not support MCS. Using MCS to access Exadata Express results in ORA-12570: TNS:packet reader failure. This restriction applies only to OCI-based drivers, such as unmanaged ODP.NET and JDBC Type 2.
