Pre-Installation Requirements for Single-Tier "Express" Edition ODBC Driver for Ingres, for Mac OS X DBMS Requirements You need to know a variety of information pertaining to your Ingres DBMS: The hostname or IP address of the Ingres DBMS server The Ingres listen address The Ingres database name Software Requirements You must have a Java Runtime Environment (JRE) that is compatible with our components. The JRE was part of the default Mac OS X installation, for Cheetah (10.0) through Snow Leopard (10.6). As of Lion (10.7), you may need to manually choose to add Java, but the OS should prompt you to do so when you try to use Java components. All Java software shipped by Apple and/or installed as part of Mac OS X, through Java 6 (a/k/a 1.6), is compatible. See 64-bit ODBC Application notes below! All Java software obtainable from Oracle for Lion (10.7) and later, i.e., Java 7 and later, is compatible. See 32-bit ODBC Application notes below! Important notes for users of 64-bit ODBC Applications: All Java software shipped by Apple and/or installed as part of Mac OS X, through Java 6 (a/k/a 1.6), is 32-bit only, and can only be used by 32-bit ODBC client applications, including iODBC Administrator.app (found in UNKNOWN tag: http://www.w3.org/1999/xhtml:nowiki/Applications/iODBC/). If you are using a 64-bit ODBC client application (e.g., Microsoft Excel 2016 or later), you must upgrade to Java 8 or later from Oracle, and then reinstall the Express Edition ODBC Driver. Important notes for users of 32-bit ODBC Applications: All Java software obtainable from Oracle for Lion (10.7) and later, i.e., Java 7 and later, is 64-bit only, and can only be used by 64-bit ODBC client applications, including iODBC Administrator64.app (found in UNKNOWN tag: http://www.w3.org/1999/xhtml:nowiki/Applications/iODBC/). If you are using a 32-bit ODBC client application (e.g., Microsoft Excel 2011 or earlier), you must downgrade to Java 6 from Apple, and then reinstall the Express Edition ODBC Driver. Important note for Snow Leopard (10.6), Leopard (10.5), and Tiger (10.4) users: PowerPC-based applications on Intel-based Macs cannot connect through our "Lite" Edition ODBC-to-JDBC Bridge, due to limitations in Mac OS X and its JRE. Commonly problematic applications include Microsoft Query as shipped with Microsoft Office:Mac v.X through Microsoft Office:Mac 2011 (upon which Microsoft Excel 2011 and earlier depend), and FileMaker Pro v8 and earlier. PowerPC-native applications on PowerPC-based Macs can connect through our "Lite" Edition ODBC-to-JDBC Bridge. Intel-native applications, and Universal Binary applications which include Intel-native components, on Intel-based Macs can connect through our "Lite" Edition ODBC-to-JDBC Bridge. PowerPC-based applications on Intel-based Macs can connect to Ingres through the Multi-Tier "Enterprise" Edition drivers. Configuration Requirements There are no software configuration requirements associated with the use of the "Express" Edition ODBC Driver for Ingres. Next... Proceed to Installation & Configuration.
