Before installing Sybase servers:

  1. Read the release bulletins for the latest information on the products (Adaptive Server, Monitor Server, and so on) that you are installing. See the “Special Installation Instructions” section in the release bulletin.

  2. Install operating system patches, if required. Required operating system patches are described in the release bulletin for the product.

    Your Sybase product shipment includes printed release bulletins; they are also availablehttp://www.sybase.com/support/manuals.

  3. Review the SySAM procedures and plan your client/server configuration using Chapter 3, “Sybase Software Asset Management (SySAM).”

  4. Create a “sybase” account on your system to perform all installation tasks.

    The “sybase” user must have permission privileges from the top (or root) of the disk partition or operating system directory down to the specific physical device or operating system file.

  5. Log in to the machine as the “sybase” user.

    It is important to maintain consistent ownership and privileges for all files and directories. A single user—the Sybase System Administrator with read, write, and execute permissions—should perform all installation, upgrade, and setup tasks.

  6. Verify that:

    Space requirements for Adaptive Server Enterprise products are listed in Chapter 2, “Installation Requirements.”

  7. Be sure you have a TEMP environment variable and a temp directory on Windows 98 (for PC-client products only), and a winnt\temp directory on Windows NT. The installation program uses the extra space and directory to write files temporarily during the installation. The installation program frees this space after the installation is complete.

  8. Adjust shared memory segments.

    Depending on the number and types of devices you use for backup (dump) and recovery (load), you may need to adjust the shared memory segment parameter in the operating system configuration file to accommodate concurrent Backup Server processes. The default number of shared memory segments available for process attachments is 6.

  9. Determine the location, type, and size of each database device.

    You must provide this information during the installation of Adaptive Server. Devices are operating system files or portions of a disk (called raw partitions) used to store databases and database objects. For details, see “Determining the location, type, and size of a database device”.
