Sybase ASE OLE DB Provider, TDS Version
The Sybase ASE OLE DB Provider connects an ADO-based
application to Sybase ASE 11.X, 12.X. The Sybase ASE OLE DB Provider is supported on current and recent
32-bit Windows operating systems Windows 9x, Windows NT 4.0 and
Windows 2000.
It is compliant with the Microsoft OLE DB 2.5 specification and
the ODBC 3.51 specification IMPORTANT NOTE: This is a special "Controlled" release of the Sybase ASE OLE DB Provider.
This OLE DB Provider does not require, nor use, the Sybase Open Client
Client-Library API. The OLE DB Provider interfaces the OLE DB (ADO) API calls
directly to the TDS wire protocol API. The name of this release may change when this product is
released as part of SDK 12.5 GA. Windows 2000 Users **** IMPORTANT!!!!!!!! ****
If you are using Windows 2000 DO NOT INSTALL MDAC 2.1 or 2.5 since
Windows 2000 already includes MDAC 2.6. This product is certified for
use on Windows 2000.
Installation Instructions
Please read the file "installoledb.txt" for installation instructions. Notes and Known Problems The following are notes, known problems, or restrictions
with Sybase ASE OLEDB Provider, 2.50. 1. On a Windows NT 4.0 machine, administrator privileges are required
to use all features of the Sybase Configuration Manager: * With the Sybase ASE OLE DB Provider, any user can
create, delete, or modify the data sources; however, a user who
does not have administrator privileges cannot change the current
directory for the Sybase ASE OLE DB Provider data sources. 2. To trace an OLE DB application, you must download the latest version
of the OLE DB Software Development Kit (SDK) from the Microsoft web
site (http://www.microsoft.com/data/oledb/). The Provider does provide
some tracing of OLE DB calls. 3. When you install a Sybase ASE OLE DB Provider to a specified directory,
it uses the default permissions for that directory (or that directory's
parent if the installation creates the directory) for the files that
get installed. The default privileges do not allow providers to act as
entrusted impersonators, which is required by IIS for this situation.
Therefore, the providers cannot be accessed or used by IIS. Workaround: Change the permissions on the directory. 4. Conversions from variant types to date/time types should always use
4-digit years. Use of 2-digit years is not supported and will result
in undefined behavior. 5. The default value of the OLE DB Services property has changed. * For the Sybase ASE OLE DB Providers, the value is -3. These
data providers enable all OLE DB Services except
DBPROPVAL_OS_TXNENLISTMENT. 6. If you created data sources for the Sybase ASE OLE燚B Provider
version 2.1 or earlier, you must create new data sources.
You cannot modify the older data sources to work with the 2.5 data
providers.
Sybase ASE OLE DB Provider
The following notes apply if you are installing the Sybase ASE OLE DB Provider. *** NOTE ****
1. The Sybase data provider does not support Microsoft DTC. 2. In an OLE DB transaction, if the user calls IRowsetChange::SetData
on any row which contains a BLOB type (i.e. Sybase's text type), the changes
made to that row cannot be rolled back via ITransaction::Abort. This situation
does NOT apply to changes made with IRowsetChange::InsertRow or
IRowsetChange: eleteRows. The following notes apply if you are installing the release on
a machine that has an earlier version of a Sybase ASE OLE DB
Provider installed. 1. If you configured a connection with a previous version of the Sybase
ASE OLE DB Provider for use with a third-party application, you can use
the same connection string. However you must recreate the Data Source.
This is due to the additional connection parameters that are required
when used with the TDS API. Contacting Sybase Technical Support ----------------------- Please report problems to Sybase Technical Support
