11g Release 1 (11.1) for Windows
This document provides late-breaking information for TimesTen ODP.NET 188.8.131.52.110 as well as information that is not yet part of the formal documentation.
This document contains the following sections:
ODP.NET supports TimesTen Release 184.108.40.206.1 or later on Microsoft Windows 32-bit and 64-bit platforms that support the TimesTen software. Oracle TimesTen Data Provider for .NET (TimesTen ODP.NET) supports the .NET 2.0, 3.0 and 3.5 frameworks with Microsoft Visual Studio 2005 or later.
You must install Oracle TimesTen In-Memory Database or TimesTen Client before you can install TimesTen ODP.NET. The 32-bit version of TimesTen ODP.NET can only be installed in a 32-bit instance of Oracle TimesTen In-Memory Database or TimesTen Client. Likewise, the 64-bit version of TimesTen ODP.NET can only be installed in a 64-bit instance of Oracle TimesTen In-Memory Database or TimesTen Client.
Before installing TimesTen ODP.NET, uninstall all other versions of ODP.NET from your Windows system. If multiple versions of ODP.NET are installed in the Global Assembly Cache, then conflicts may occur at runtime.
In addition to the environment variables required for Oracle TimesTen In-Memory Database or TimesTen Client, make sure the PATH environment variable includes the TimesTen_install_dir\ttoracle_home\instantclient_11_1\bin directory.
TimesTen ODP.NET support has been added for 64-bit Microsoft Windows platforms that support the TimesTen software.
TimesTen ODP.NET requires TimesTen Release 220.127.116.11.1 or later.
In previous releases, an attempt to use a ref cursor could result in error messages such as "Statement handle not executed" or "Invalid cursor handle". This problem has been fixed. (BugDB 9484387, 9488408, 9561212 and 9571131)
In previous releases, using PL/SQL OUT parameters for character types would result in data corruption or unpredictable behavior such as a "Character data loss in NCHAR/CHAR conversion" error. This problem has been fixed. (BugDB 9563921 and 9645613)
Passing arrays of parameters to PL/SQL procedures and functions is not supported. An attempt to pass a parameter array to PL/SQL can result in data corruption or various error messages such as a "Wrong number or types of arguments in call" or "Argument is an invalid or uninitialized number". (BugDB 9645256, 9645633 and 9651212)
When using the 64-bit version of TimesTen ODP.NET, a crash, data corruption or other exceptions may occur when executing statements or commands that bind arrays of parameters. (BugDB 9555440 and 9820678)
Only one installation of TimesTen ODP.NET can exist on a system. Uninstall any previous version of TimesTen ODP.NET before installing a new version.
Exception "ORA-44818: PL/SQL feature not installed in this TimesTen database"
Enable PL/SQL for the database by setting the PLSQL DSN attribute to 1 in the odbc.ini file or ODBC Data Source Administrator. TimesTen ODP.NET applications can only connect to PL/SQL-enabled TimesTen databases.
Exception "TimesTen database version is less than the minimum required version of 18.104.22.168.1"
Change the entry in the TimesTen tnsnames.ora file to reference a TimesTen database of version 22.214.171.124.1 or greater. TimesTen ODP.NET applications can only connect to TimesTen databases of version 126.96.36.199.1 or greater.
Exception "ORA-12154: TNS:could not resolve the connect identifier specified" or "ORA-12541: TNS:no listener"
If using the tnsnames naming method to connect, then verify that an entry in the tnsnames.ora file is associated with a TimesTen DSN. Also, verify that the TNS_ADMIN environment variable is set to the directory where the tnsnames.ora file resides.
If using the Easy Connect naming method to connect, then verify that service_name is set to a TimesTen DSN, and server is set to either timesten_direct or timesten_client depending on whether the DSN configures a direct connection or a client/server connection.
In a TimesTen ODP.NET application, the Data Source attribute in the ODP.NET connection string must be set to either a TimesTen entry in the tnsnames.ora file or a TimesTen Easy Connect string.
Exception "ORA-29158: Unable to open library"
Verify that either the entry in the tnsnames.ora file is associated with a TimesTen DSN or service_name in the Easy Connect string is set to a TimesTen DSN.
Exception "Failure to load dependent library OraOps11w.dll"
Uninstall any previous versions of ODP.NET. Also, run the uninstall_ttodp.bat script from the TimesTen_install_dir\ttoracle_home\instantclient_11_1 directory to uninstall TimesTen ODP.NET. Then, reinstall TimesTen ODP.NET and make sure the PATH environment variable contains the TimesTen_install_dir\ttoracle_home\instantclient_11_1\bin directory.
The cause of the exception is that either another version of ODP.NET is installed, TimesTen ODP.NET is not installed, or an existing installation of TimesTen ODP.NET is damaged.
