In this case you need to start the JVM with an additional start-up parameter to specify the mode. Some JVMs offer both modes: 32-bit as well as 64-bit. The 64-bit variant should always be preferred on 64-bit platforms. If you have to use a 32-bit Java VM on a 64-bit platform, download and use the 32-bit version of JCo. You only need the 64-bit version of the SAP Java Connector if you are using a 64-bit Java VM.
In case you have installation instructions from some other component, they usually refer to the nested archive. Extract the nested archive variant from the downloaded archive first.The SDK archives for the Unix versions of the SAP Java Connector are shipped as a TGZ file embedded in a ZIP file.
