iAnywhere Solutions 12 - Oracle ODBC driver

The iAnywhere Solutions 12 - Oracle ODBC driver is custom-tailored for use with iAnywhere software. This driver does not work with third-party software.

If you use Oracle with MobiLink or remote data access, you must install an Oracle client on the same computer as this Oracle driver.

The Oracle driver can be configured using the ODBC Administrator, the .odbc.ini file (in Unix), or the dbdsn utility.

The following table provides the configuration options for the Oracle driver.

Windows ODBC Data Source Administrator	Configuration for dbdsn command line or .odbc.ini file	Description
Data source name	For dbdsn, use the -w option.	A name to identify your data source.
User ID	UserID In dbdsn, set this option in the connection string.	The default logon ID that the application uses to connect to your Oracle database. If you leave this field blank, you are prompted for the information when you connect.
Password	Password In dbdsn, set this option in the connection string.	The password that the application uses to connect to your Oracle database. If you leave this field blank, you are prompted for the information when you connect.
ServiceName	ServiceName	The TNS Service Name that is stored in network/admin/tnsnames.ora under your Oracle installation directory.
Enable Microsoft distributed transactions	For dbdsn, use the enableMSDIC option in the connection string. Not supported for .odbc.ini.	Select this checkbox if you want to enlist your transactions in the Microsoft Distributed Transaction Coordinator. When selected, the Oracle ODBC driver requires an Oracle binary file, oramts.dll for Oracle 9i clients or oramts10.dll for Oracle Database 10g clients.
Encrypt Password	For dbdsn, use the -pe option. Not supported for .odbc.ini.	Select this checkbox if you want the password to be stored in encrypted form in the data source.
Procedure returns results or uses VARRAY parameters	ProcResults In dbdsn, set this option in the connection string. ProcOwner In dbdsn, set this option in the connection string.	Select this field if your stored procedures can return results or if the stored procedures use Oracle VARRAYs. The default is that this option is not selected. If your download_cursor or download_delete_cursor scripts are stored procedure invocations, select this checkbox. If no stored procedures use VARRAYs and none of them returns a result set, uncheck this checkbox to improve performance.
Array Size	ArraySize In dbdsn, set this option in the connection string.	The size, in bytes, of the byte array used to prefetch rows, on a per-statement basis. The default is 60000. Increasing this value can significantly improve fetch performance (such as during MobiLink server downloads) at the cost of extra memory allocation.

To create an ODBC data source for the Oracle driver in Windows

Open the ODBC Administrator:
- Choose Start » Programs » SQL Anywhere 12 » Administration Tools » ODBC Data Source Administrator.
The ODBC Data Source Administrator appears.
Click Add.
Choose iAnywhere Solutions 12 - Oracle and click Finish.
Specify the configuration options you need. The fields are explained above.
Click Test Connection, and then click OK.

On Unix, if you are setting up the driver in an ODBC system information file (typically called .odbc.ini), the section for this driver should appear as follows (with appropriate values entered for each field):

[sample_dsn_using_the_ias_odbc_driver_for_oracle]
Driver=full-path/libdboraodbc10_r.so
UserID=user-id
Password=password
ServiceName=TNS-service-name
ProcResults=[yes|no]
ArraySize=bytes

For an explanation of each field, see above.

DBDSN configuration

To create an Oracle DSN with the dbdsn utility, use the following syntax:

dbdsn -w data-source-name -or -c configuration-options

The configuration-options are described above.

For example:

dbdsn -w MyOracleDSN -or -pe -c Userid=dba;Password=sql;ServiceName=abcd;ArraySize=100000;ProcResults=y;enableMSDIC=n

See Data Source utility (dbdsn).
