Before installing Adaptive Server:
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.
Install operating system patches, if required.
For information about operating system requirements, see “System requirements”.
If you are having trouble starting the installer, make sure you have the required operating system patches for the Java Runtime Environment (JRE) version 1.4.2.
Information about the required operating system patches is available from the Sun Java Web site.
Review the SySAM procedures and plan your client/server configuration using the configuration guide for your platform.
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.
Log in to the machine as the “sybase” user.
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.
Decide where the Adaptive Server software will be installed. Make sure there is sufficient available disk space. There cannot be any spaces in the path name of the directory.
Know what product edition you are installing. The options are:
Enterprise Edition
Small Business Edition
Developers Edition
Express Edition
If you are installing the Small Business or Enterprise Edition, you must know the license type under which Adaptive Server was licensed. For more inforamtion about license types, see the “License types” in Chapter 3 “Getting and Using your License” of the Sybase Software Asset Management User’s Guide.
Sybase recommends that you specify license types at the time of installation. However, you may choose to specify the product edition and license type later using sp_lmconfig. For information on sp_lmconfig, see Reference Manual:Procedures.
You must decide if you want licensing events to trigger e-mail alerts and the severity of the events that will generate e-mail messages .
If you choose to have e-mail notification of license events, you must know the:
SMTP server host name
Port number for an SMTP server
E-mail return address
Recipients of the notifications
Severity level of an event that will trigger mail. Your choices are:
None
Informational
Warning
Error
Verify that the operating system meets the version-level, RAM, and network protocol requirements for your platform.
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.
The operating system shared memory default, for most Linux releases is 32MB. The minimum required by Adaptive Server is 64MB for default Server with 2K pages. A higher value is required if you plan to increase Adaptive Server’s total memory.
Use the sysctl(8) method to check and adjust the operating system shared memory parameter.
To check the current shared memory size, enter:
# /sbin/sysctl kernel.shmmax
To adjust the shared memory size:
# /sbin/sysctl -w kernel.shmmax=nnn
where nnn is the new size in bytes (at least 64MB, which is 67108864 bytes).
To guarantee that this value is applied every time the system is started, add the above line to your /etc/rc.d/rc.local file. On SuSE systems, the file is /etc/init.d/boot.local.
On Linux RHEL Update 3.0 and greater, Adaptive Server version 15.0 running on multiple engines requires the security feature Exec-Shield to be disabled.
To disable Exec-Shield:
Add the following lines in /etc/sysctl.conf:
kernel.exec-shield=0 kernel.exec-shield-randomize=0
As SU, enter:
/sbin/sysctl -P
for the action to take effect.
