The Add button lets you add locations to the list. The Delete button lets you remove locations from the list. The locations must be on the same server where the database engine is running. Specify the location in the same manner as for the dictionary locations. For example:. The specific driver specified by the Driver parameter has additional attribute parameters for naming the server, port, database, etc. In addition to these common parameters, each driver has parameters specific to it.
The tables below show, for the different drivers, the driver parameters that may be used. Specify the machine name or IP address of the computer to which you wish to connect. Port is provided from backwards compatibility and allows you to specify the port number to use if you are not using the default port. Specify the internal database name not DSN to which you wish to connect. The character is optional. It has no particular effect and is supported only for backward compatibility. Specify whether to cache result sets on the client.
Specify the size of the client cache, in KB. Default is 8 KB. Specify how to handle the data encoding when the client connects to the database engine. See Encoding Translation for more information. Data translation, if required, occurs on the client. If security is enabled for the given database, specify the user name. Optional, depending on security. If security is enabled for the given database, specify the password. Table 15 bit Driver Connection String Parameters.
If the attribute is absent, ODBC does not translate any character data. This is the default behavior. Specify the Engine DSN to which you wish to connect. Required, unless DBQ is specified. Table 17 bit Engine Driver Connection Strings. Specify the default file open mode for files opened with the current connection. Driver Name. PSQL Driver. Microsoft Driver Manager Text Handlling. Client encoding to OEM. Client encoding to database encoding.
UCS-2 to client encoding. UCS-2 to database encoding. The default is write access. Enable Closing Cursors - Enables closing cursors. By default, closing cursors is disabled the field is empty , meaning a call to close a cursor does not force the closing of OCI cursors when this behavior is not desired because it can cause an unnecessary performance hit.
Enable closing cursors when you want to force the closing of OCI cursors upon a call to close a cursor.
Enable Thread Safety - Thread safety can be disabled for a data source. If thread safety is not required, disabling this option eliminates the overhead of using thread safety. By default, thread safety is enabled. Batch Autocommit Mode - By default, commit is executed only if all statements succeed. Numeric Settings - Allows you to choose the numeric settings that determine the decimal and group separator characters when receiving and returning numeric data that is bound as strings.
The following list is an explanation of the fields found on the Oracle Options tab shown in the preceding graphic:. Fetch Buffer Size - The amount of memory used to determine how many rows of data the ODBC Driver prefetches at a time from an Oracle database regardless of the number of rows the application program requests in a single query.
However, the number of prefetched rows depends on the width and number of columns specified in a single query. Applications that typically fetch fewer than 20 rows of data at a time improve their response time, particularly over slow network connections or to heavily loaded servers.
Setting Fetch Buffer Size too high can make response time worse or consume large amounts of memory. There is a small performance penalty for insert and update statements when LOBs are enabled.
Enable Statement Caching - Enables statement caching feature, which increases the performance of parsing the query, in case the user has to parse the same text of query and related parameters multiple times.
The default is disabled. The default cache buffer size is 20 that are used only if statement caching option is enabled.
Setting cache buffer size to 0 disables statement caching feature. The default size is 8 KB bytes. The maximum value that can be set is KB bytes. Translate ORA errors - Any migrated third party ODBC application, which is using the SQL Translation Framework feature, expects that errors returned by the server to be in their native database format, then users can enable this option to receive native errors based on the error translation registered with SQL Translation Profile.
Convert Empty String - Any third party ODBC application that is migrated to Oracle Database requires handling empty string data Oracle Database does not handle empty string data in table columns , then they can enable this option so that the application can insert empty string data or retrieve empty string data. Enable this option to configure additional failover retries. The default is enabled. Retry - The number of times the connection failover is attempted.
The default is 10 attempts. Delay - The number of seconds to delay between failover attempts. The default is 10 seconds. The following list is an explanation of the fields found on the Workarounds Options tab shown in the preceding graphic:. For more information, see Section This support is disabled by default.
ODBC calls made by the application to specifically change the value of the attribute after connection time are unaffected by this option and complete their functions as expected. By default, this option is off. This enhancement improves the performance of Oracle ODBC driver up to 10 times, depending on the prefetch size set by the user. The default value is 0. The maximum value that you can set is 64 KB bytes.
If the value of prefetch size is greater than , the data fetched is only bytes. If you pass a buffer size less than the prefetch size in nonpolling mode, a data truncation error occurs if the LONG data size in the database is greater than the buffer size. By default, this function is enabled. A subprogram call specified in an EXEC statement is translated to its equivalent Oracle subprogram call before being processed by an Oracle database server.
By default this option is disabled. Schema , which is the translated Oracle subprogram assumed to be defined in the user's default schema. However, if all subprograms from the same SQL Server database are migrated to the same Oracle schema with their database name as the schema name, then set this field to database. If all subprograms owned by the same SQL Server user are defined in the same Oracle schema, then set this field to owner.
This field is empty by default. An Oracle server waits indefinitely for lock conflicts between transactions to be resolved. The value you enter for the LockTimeOut parameter is the number of seconds after which an Oracle server times out if it cannot obtain the requested locks.
In the following example, the Oracle server times out after 60 seconds:. As part of the connection process, an application can prompt you for information.
If an application prompts you for information about an Oracle data source, do the following:. An application must connect to a data source to access the data in it.
Different applications connect to data sources at different times. For example, an application might connect to a data source only at your request, or it might connect automatically when it starts.
For information about when an application connects to a data source, see the documentation for that application. To verify this, type PATH from a command prompt. All ; config. ComponentModel; using System.
Data; using System. Drawing; using System. Text; using System. Tasks; using System. Text; if city! Customers where c. This would be the most reliable solution based on your description of your needs. Not trying to sound discouraging -- just if you are going to do something of this magnitude -- the success of the effort will be based on doing it right as opposed to the nickel and dime way.
Rich P. Thursday, August 7, PM. From what you describe -- you need a server based system like Sql server that can use an IP address. Access is a file based system -- basically JUST a file like test1. The connection strings described below combine all the information EFT needs to connect to the database. If you have several simultaneous database connections, a DSN-less connection may be slightly faster than a DSN connection; however, a DSN-less connection is hard-coded to use a certain driver, user identity, and network location, and needs to be updated when the database parameters change.
In the Authentication Provider Options dialog box, type the connection string per the guidelines below.
You must know the correct driver to use with your database. Create a connection string as described below and type it into the Authentication Provider Options dialog box.
