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.
Adjust the Shared Memory Allocation
The -iqsmem switch for shared memory allocation now supports values greater than 512MB on 64-bit IBM AIX platforms. The maximum supported limit for a single shared memory segment on AIX-64 increased from 256MB to 32TB. Adjusting this switch results in a significant performance increase.
Installing the IBM XL C/C++ Redistributable Libraries
Sybase IQ depends on some redistributable libraries included with IBM XL C/C++ V10.0 and higher. If you are using an XL C/C++ compiler that is less than version 10.0, update your environment with these libraries.
Increase the Maximum User Processes
For new installations, the default setting is 40. For a production system, set this value to a minimum of 250. See your operating system documentation for information on setting this parameter.
