5.3.1. Creating ODBC Data Sources OpenLink Software's components are fully supported on Mac OS X version 10.1.x ('Puma') and 10.2.x ('Jaguar'). In most ways, this looks the same to users. However, there are some significant differences to be aware of between these Operating Systems. As shipped from Apple, Mac OS X did not include any ODBC support until Jaguar. The ODBC Driver Manager, Data Source Administrator, etc.

all had to be delivered with the Drivers. When Apple introduced Darwin, an Open-Source project meant to form the kernel of Mac OS X, OpenLink determined to port its open-source iODBC Driver Manager to the new platform. With the introduction of the Preview Release of Mac OS X, the traditional set of dynamic libraries was broadened to include a system of Frameworks to encourage the development of fully ODBC compliant, native Mac OS X drivers and client applications.

That set of Frameworks, along with the OpenLink ODBC Administrator (then known as the iODBC Administrator), has been included with all OpenLink installations for Mac OS X since 10.0. The OpenLink ODBC Administrator supports all core features of ODBC, and presents driver-specific DSN configuration panels, as defined by the Driver developer, through the use of Setup Libraries. Jaguar's release marked Apple's recognition that Data Access was an important part of an Enterprise Operating System. Already part of the standard distribution of Darwin, the basic iODBC dynamic libraries are now a part of the standard installation of Mac OS X 10.2. Apple also included their own version of an ODBC Administrator, as a proof-of-concept. Apple's Administrator permits Driver Registration, Tracing, and all other core features of ODBC; however, among other hard edges, all DSN configuration must be done by manually entering Keyword-Value pairs. Further, the user must know what Keywords to use, along with their acceptable Values.

The Drivers tab of the OpenLink ODBC Administrator will likewise display versions of all installed drivers; Apple's ODBC Administrator does not display driver versions. Making a connection with the sample iODBC Test.command will also display version information for the driver in use for that DSN. IODBC provides a GUI administrator tool for configuring drivers and DSNs; however, this tool has not been tested for use with Snowflake and, therefore,. This section names each of the ODBC data sources that appear in the odbc.ini file. It also pairs the appropriate ODBC driver name with the data source name. Data Source Specifications: This section lists the actual data source names. Each data source name is composed of a.

Mac OS X ODBC Data Sources The OpenLink ODBC Administrator for Mac OS X currently supports creation of User and System Data Source Names (DSNs). Support for File DSNs will be delivered in a future release. A User DSN is only available to the user who creates the data source. Its parameters are stored in that user's settings file /Library/Preferences/ODBC.preference. A System DSN is available to the whole system so that any user, including the system itself, will be able to use that data source. Its parameters are stored in the System settings file /Library/Preferences/ODBC.preference. A File DSN is a special 'mobile' data source that stores the data source information associated with the Driver in a file, which may then be copied and shared among different users and ODBC application host machines.

The steps for creating a DSN are as follows. The name of the ODBC DSN. This is how you will generally refer to this data source, from within ODBC client applications. Description. Any extra information you wish to note about the DSN you are creating. This is generally not displayed by ODBC client applications, though it is available to them. This is the fully qualified hostname, or IP address, of the machine hosting the DBMS you wish to access, e.g., dbms-server.example.com, or 192.168.155.123.

Any hostname which will be resolved by your local DNS is acceptable. Server Type. Select the version and/or vendor of the DBMS engine you will be accessing, from the list presented. If your exact version is not listed, try the closest version available. If that fails, please contact OpenLink Technical Support. This specifies the default username to be used when attempting to make a connection. You may override this at run time.

Row Buffer Size. This attribute specifies the number of records to be returned in a chunk. Values may range from 1 to 999. Setting this value too high or too low can significantly impact performance. Generally, best results are achieved with values between 50 and 150. Hide Login Dialog. Suppress the ODBC 'Username' and 'Password' login dialog box when interacting with your ODBC DSN from within an ODBC compliant application.

Please note - this requires that these values be correctly specified within the DSN, which can open a security hole. Read Only connection.

Specify whether the connection is to be 'Read-only'. Make sure the checkbox is unchecked to request a 'Read/Write' connection. Initialization SQL. Lets you specify a file containing SQL statements that will be run against the database upon connection, automatically. MaxRows Override. Allows you to limit the maximum number of rows to return from a query. The default value of 0 means no limit.

Enable Microsoft Jet Engine Options. Extra support or altered functionality for better compatibility with Microsoft Jet using applications such as Microsoft Access. This generally doesn't apply to Macintosh applications; however, we retain the option. Disable AutoCommit. Change the default commit behaviour of the OpenLink Lite Driver. The default mode is AutoCommit mode (box unchecked). Disable Rowset Size Limit.

Disable any limitation enforced by the cursor library. The limitation is enforced by default, to prevent the Driver claiming all available memory when a result set is very large. The limit is normally never reached. High Cursor Sensitivity Enables or disables the row version cache used with dynamic cursors. When dynamic cursor sensitivity is set high, the Cursor Library calculates checksums for each row in the current rowset and compares these with the checksums (if any) already stored in the row version cache for the same rows when fetched previously. If the checksums differ for a row, the row has been updated since it was last fetched and the row status flag is set to SQLROWUPDATED.

The row version cache is then updated with the latest checksums for the rowset. From the user's point of view, the only visible difference between the two sensitivity settings is that a row status flag can never be set to SQLROWUPDATED when the cursor sensitivity is low. (The row status is instead displayed as SQLROWSUCCESS.) In all other respects, performance aside, the two settings are the same - deleted rows don't appear in the rowset, updates to the row since the row was last fetched are reflected in the row data, and inserted rows appear in the rowset if their keys fall within the span of the rowset. If your application does not need to detect the row status SQLROWUPDATED, you should leave the 'High Cursor Sensitivity' checkbox unchecked, as performance is improved. The calculation and comparison of checksums for each row fetched carries an overhead. For this option to take effect, the table 'oplrvc' must already have been created, using the appropriate script for the target database.

Defer fetching of long data. Checked by default, this parameter determines whether long-data fields are retrieved after all other fields in a query, or in whatever order they appear in the query. Performance is generally best with this enabled; hence the default setting. Server Type - An OpenLink proprietary parameter that associates the connection with a particular TDS version. Hostname - The hostname or IP address on which SQL Server listens. Port number - The TCP port on which SQL Server lists. Server Name - SQL Server instance name on the specified host.

A SQL Server instance can also be specified by appending ' InstanceName' to the ServerName, ie 'ServerName InstanceName'. Mirror Host - The name of the Failover Server hosting the mirrored database if configured. Use strong encryption of data - Enable SSL encryption of data between driver and database. Use Mars - Multiple Active Result Sets enables the concurrent processing of multiple statements/queries and/or result sets on a single connection. Verify Server Certificate - Verify the Database Server SSL certificate against the one specified in the 'CA file' field.

CA file - Specify the location of a Valid SSL Certificate for use during the connection Click OK to continue. The Connection Tab takes a combination of required and optional parameters required to make a connection to the target database. Row Buffer Size - This attribute specifies the number of records to be transported over the network in a single network hop.

Values can range from 1 to 99. Hide Login Dialog - Suppresses the ODBC 'Username' and 'Password' login dialog boxes when interacting with your ODBC DSN from within an ODBC compliant application. Read Only connection - Specifies whether the connection is 'Read-only.' Make sure the checkbox is unchecked to request a 'Read/Write' connection. TDS packet size - A value that determines the number of bytes per network packet transferred from the database server to the client.

The correct setting of this attribute can improve performance. When set to 0, the initial default, the driver uses the default packet size as specified in the Sybase server configuration. When set to -1, the driver computes the maximum allowable packet size on the first connect to the data source and saves the value in the system information. When set to x, an integer from 1 to 10, which indicates a multiple of 512 bytes (for example, Packet Size of 6 means to set the packet size to 6.

512 equal 3072 bytes). For you to take advantage of this connection attribute, you must configure the System 10 server for a maximum network packet size greater than or equal to the value you specified for Packet Size. Prepare Method - This option is specific to the TDS Driver for MS & SQL Server SQLServers. It can take the values None, Partial Full (connectoptions -O 0, 1, 2 respectively). It is used to determine whether stored procedures are created on the server for calls to SQLPrepare. No Quoted Identifiers - This option indicates that the underlying driver does not support quoted identifiers, which is required for Jet engine based products like MS Access. Use ANSI nulls, padding and warnings - This option affects TDS agent & Lite Driver connections to MS SQLServer databases.

SQL Server connectivity is not affected. Map Serializable to Snapshot isolation level - Enable Snapshot transaction isolation level in the driver. Snapshot Isolation is a new transaction isolation level available in SQL Server 2005. SQLDBMS Name - Manually overrides theSQLGetInfo(SQLDBMSNAME) response returned by the driver.

This is required for products like MicrosoftInfoPath for which the return the value should be 'SQL Server'. Click Continue to view additional preferences that can be set for the connection. Initialization SQL - Lets you specify a file containing SQL statements that will be run automatically against the database upon connection. Cursor Sensitivity - Enables or disables the row version cache used with dynamic cursors. When dynamic cursor sensitivity is set high, the Cursor Library calculates checksums for each row in the current rowset and compares these with the checksums (if any) already stored in the row version cache for the same rows when fetched previously.

If the checksums differ for a row, the row has been updated since it was last fetched and the row status flag is set to SQLROWUPDATED. The row version cache is then updated with the latest checksums for the rowset. From the user's point of view, the only visible difference between the two sensitivity settings is that a row status flag can never be set to SQLROWUPDATED when the cursor sensitivity is low. (The row status is instead displayed as SQLROWSUCCESS.) In all other respects, performance aside, the two settings are the same. Deleted rows don't appear in the rowset. Updates to the row since the row was last fetched are reflected in the row data, and inserted rows appear in the rowset, if their keys fall within the span of the rowset. If your application does not need to detect the row status SQLROWUPDATED, you should leave the 'High Cursor Sensitivity' checkbox unchecked, as performance is improved.

The calculation and comparison of checksums for each row fetched carries an overhead. If this option is enabled, the table oplrvc must have been created beforehand using the appropriate script for the target database. MaxRows Override - Allows you to define a limit on the maximum number of rows to be returned from a query. The default value of 0 means no limit. Enable Microsoft Jet Engine options -. Disable rowset size limit - Removes OpenLink's default 100-row rowset restriction. Defer fetching of long data - Defers fetching of LONG (BINARY, BLOB etc.) data unless explicitly requested in a query.

This provides significant performance increases when fields in query do not include LONG data fields. Multiple Active Statements Emulation - Click the Finish button to save your new Data Source Name. Adjust Clock. When selected the???? For daylight saving changes.

This is so that???. Choose a Database. If selected the pick options for the Database name and Character set are accessed from the datasource.

This field is enabled if the above field is checked. Password is used to make a connection to the datasource to obtain the choices for subsequent fields.

The name of the Virtuoso database that is to be accessed by the data source. This is a dynamically generated menu, showing only those databases actually available on the data source when the DSN is configured. If you need to manually specify this information, you may edit the appropriate ODBC.preference text file. Please contact OpenLink Technical Support, for assistance. Character Set.

The name of an installed character set on the Virtuoso server. The default is the setting active on the Virtuoso Server.

This is a dynamically generated menu, showing only those databases actually available on the data source when the DSN is configured. If you need to manually specify this information, you may edit the appropriate ODBC.preference text file. Please contact OpenLink Technical Support, for assistance. Unsuccessful test connections may present any of a number of error messages.

To resolve those errors, please refer to the troubleshooting section of this manual. For more thorough testing, you can use odbctest, a sample application installed along with the OpenLink Lite Driver. Odbctest is a simple command-line, ODBC compliant, Interactive SQL client. It may be accessed through the Terminal application, by issuing the command /Library/iodbc/bin/odbctest At the SQL command prompt enter '?' For a list of ODBC DSNs on your machine, or enter a valid ODBC Connect String (e.g., with the DSN created above, named 'DEMO', you would enter: DSN=DEMO;UID=;PWD= ).

From here, any valid SQL Statement may be executed. Generally, you will need to know a valid table name within the database to be able to retrieve information from it. Within odbctest, the command 'tables' will return a list of all tables accessible through your active connection. If the query executes successfully you will see a table of the data returned by the query; if unsuccessful, you will see the entire error message returned from the backend DBMS.

Hi Erik, I get the feeling Linda has never used ODBC. Yes, the drivers she pointed you to do work, but they don't have anything to do with your question, and they don't work with Amazon Redshift as far as I know. I looked around the RedShift documentation you linked to, but did not find any reference to a test database. As I don't have a RedShift account, I personally don't have a way to test their driver.

When you say 'everything is working perfectly on the system level' does that mean you can successfully set up and test the ODBC connection using Apple's ODBC Manager.app in Applications Utilities? You have to use Apple's ODBC Manager app to set up either system or user Data Source Names (DSN) before you can use a DSN in Excel. I am an unpaid volunteer and do not work for Microsoft.
