Preparing to Install Adaptive Server

Before you start the installer, perform tasks to prepare your system.

1. Verify that you have gzip installed on your machine so the installer can decompress files during the installation process. If you do not have gzip, the installer displays a message similar to the following, and the installation fails:

   gzip: Not found

2. Ensure that the account used to start the server has read and write permissions for the directory in which you are installing the server. You may need to create nonadministrative logins to install the server into personal directories.
3. Review the SySAM licensing procedures, and plan your server configuration using the configuration guide for your platform.
4. For consistency and security, create a Sybase account with administrative privileges. This user account could be "sybase" or any other user name. Use this account to perform all installation and device-creation tasks.

   This 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. 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.

   If you are installing Adaptive Server on more than one computer, create the “sybase” user account on each machine.

5. Log in to the machine as “sybase.”
6. If you have enabled the Java in the database feature, create the sybpcidb database and disable the feature during the installation. See Managing Java in the Database During Installations and Upgrades.
7. Decide where to install Adaptive Server:
   • Make sure there is sufficient disk space and temporary directory space available.
   • Ensure there are no spaces in the path name of the directory.
8. Decide whether you want licensing events to trigger e-mail alerts, and the severity of the events that generate e-mail messages.
   If you choose to have e-mail notifications for license events, know your:

   • SMTP server host name
   • Port number for an SMTP server
     Note: If Sybase assigns any port numbers to you for use with Adaptive Server, exclude these numbers from any port-scanning software you run. Adaptive Server attempts to service each scan as a login attempt, which may lead to poor performance.
   • E-mail return address
   • Recipients of the notifications
   • Severity level of an event that triggers mail. Your choices are:
     • None
     • Informational
     • Warning
     • Error
9. 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.

10. Adjust the shared memory for your operating system.

• Adjusting the Operating System Shared Memory Parameters
  Adjust shared memory segments if Adaptive Server cannot obtain large memory as a single segment, or if Backup Server stripes fail due to insufficient segments.
• Managing Java in the Database During Installations and Upgrades
  If you have enabled the Java in the database feature, create the sybpcidb database before installing or upgrading to Adaptive Server version 15.7 SP100.
• Multipathing
  Multipathing is the ability of a server to communicate with the same physical or logical block storage device across multiple physical paths between the host bus adapters (HBA) in the server and the storage controllers for the device, typically in Fibre Channel (FC) or iSCSI SAN environments. You can also achieve multiple connections with direct attached storage when multiple channels are available.
