Perform the following tasks before you install
SAP Sybase IQ.
Check for Operating System Patches
Check with your vendor and apply the latest operating system patches. Do not use a patch that is earlier than the version suggested for your operating system.
Increase the Swap Space
The recommended minimum swap space is at least 1GB. Certain operations may cause the memory usage to grow dynamically. Changing the way SAP Sybase IQ uses buffers can dramatically change the way it uses memory.
License Server Requirements
SAP Sybase IQ requires SySAM license server version v11.6.1 or later, which is distributed on the SAP Sybase IQ Server Suite installation media. Using an older SySAM server can cause the server to become unresponsive. Install the license server before you install SAP 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.
Enable the I/O Completion Ports (IOCP)
AIX I/O Completion Port (IOCP) status may be defined, but not enabled. This problem applies to all AIX platforms and may occur after an install or upgrade. .
Installing the IBM XL C/C++ Redistributable Libraries
SAP 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.
