Customers typically installed earlier releases of Sybase software using CDs. However, with the widespread use of electronic software distribution, most customers download Adaptive Server 15.0 from the Sybase Product Download Center (SPDC). The downloaded software is in the format of a CD image, so you can burn it to a CD and install it from this image, if necessary. To avoid installation problems, consider the following:
Make sure you use a short path to a download location (for example, /sybase/downloads or c:\sybase\downloads). The path should not contain any special characters, such as the space character. On Windows operating systems, do not use directories such as C:\Program Files\Sybase\downloads (the space between “Program” and “Files” is a problem). Using bad paths or using the wrong version of the JRE results in “class not found” installation failure errors.
Adaptive Server ships with the correct JRE for the InstallShield utility. If you have other Java environments installed (for example, JDK or JRE), and have environment variables referencing these locations (for example, JAVA_HOME, or if you include java in your path environment variable for frequent compilations), disable these environment variables in the shell from which you start the installation.
Use the GNU gnuzip utility to uncompress the CD images on UNIX systems. These images have been compressed using the GNU zip utility, and decompressing them with standard UNIX compression utilities can corrupt the images.
Use GNU tar utility to extract the archive files for the CD image. The standard UNIX tar utility may not extract the files correctly.
Many of the hardware vendors support a variety of mount options for their CD drives, see the installation guide to make sure you are using the correct mount options specified for your platform.
