Pre-installation tasks

Before installing Adaptive Server:

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

  2. Install operating system patches, if required.

    Recommended operating system patches are:

  3. If you are installing multiple server, you should review the SySAM procedures and plan your client/server configuration using the Configuration Guide for your platform.

  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.

    Add /usr/bsd to your path.

    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. Decide where the Adaptive Server software will be installed. Make sure that there is sufficient available disk space. There cannot be any spaces in the path name of the directory.

  7. Verify that the operating system meets the version-level, RAM, and network protocol requirements for your platform.

  8. Verify that your network software is configured.

    Sybase software uses network software even if Adaptive Server and Sybase client applications are installed on a machine that is not connected to a network.

    If you are having connection problems, or to verify your network configuration, ping the host.

  9. Adjust the operating system shared memory parameter, if necessary.

    For Adaptive Server to run, the operating system must allow allocation of a shared memory segment at least as large as the Adaptive Server total logical memory configuration parameter.

    The default size limit for shared-memory segments on IRIX 6.5 is 80 percent of physical memory, which should be sufficient. To verify the current setting, use:

    systune shmmax
    

    To adjust the setting, log in as “root”, and use:

    systune shmmax nnn
    

    where nnn is at least 28MB for a default Adaptive Server.

    After you install Adaptive Server, you can change any configuration parameter, procedure cache size, and data cache size. This may also require you to increase the configuration parameter max memory.

  10. 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 2000. To determine whether the limit has been configured differently, use:

    systune sshmseg
    

    Adaptive Server may allocate shared memory segments after start-up if any reconfiguration through sp_configure requires additional memory. You may need to account for these additional segments. Allocate the maximum memory you will make available to Adaptive Server, by using the allocate max shared memory configuration parameter. See the System Administration Guide for more information.
