Preinstallation Tasks

Perform the following tasks before you install Sybase IQ. You may need to refer to your operating system documentation for specific commands.

• Check for Operating System Patches
  Apply any operating system patches before you install Sybase IQ. Check with your operating system vendor for information on the latest operating system patches.
• Increase the Swap Space
  The recommended minimum swap space to run Sybase IQ is at least 1GB. Certain operations may cause the memory used by Sybase IQ to grow dynamically. Changing the way Sybase IQ uses buffers can dramatically change the way it uses memory.
• Sybase IQ May Require a New License Server
  Sybase IQ requires SySAM license server version v11.6.1 or later, which is distributed on the Sybase IQ Server Suite installation media. Using an older SySAM server can cause the Sybase IQ server to become unresponsive. Install the license server before you install Sybase IQ.
• Manage Shared Memory
  In some cases, increasing the shared memory segment can lead to better network performance.
• Set the File Descriptor Limits
  To use the Solaris debugger, add a file descriptor for each thread in addition to the file descriptors for each dbspace.
• Verify Network Functionality
  Make sure your network devices can communicate before you install Sybase IQ.
