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.
• Install 32-bit Compatibility Libraries
  Red Hat Enterprise Linux 6 requires 32-bit compatibility libraries to support Java-based applications in Sybase IQ, including the Sybase IQ installer.
• 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.
• Resolve Potential Name Conflicts
  Red Hat Linux includes a unixodbc package that can cause name conflicts with components provided with Sybase IQ. To avoid name conflicts, rename the files.
• Set the Kernel Parameters
  Set the number of available semaphore identifiers to at least 4096.
• Install the Required Package Groups
  Linux x86-64 requires 32-bit libraries to run some client applications.
• Verify Network Functionality
  Make sure your network devices can communicate before you install Sybase IQ.
