Computer node implementation checklist

You can review the computer node implementation checklist for specific recommendations.

Table 1. Computer server node implementation recommendations
Recommendation Section Dev Prod Comments
OS Version and OS Kernel Parameters Supported configurations C C Make sure you install the Sterling™ Order Management System Software system on certified OS versions and levels.
Network Speed and Duplex Negotiation Auto-negotiation C C Make sure your network cards are operating at the highest speeds. The network interface card and the network switch can negotiate to lower speed and duplex. When that happens, performance degrades noticeably, even under low transaction volumes.
AIX® Recommendations      
Page Space Allocation Page space allocation policy C C The AIX default page space allocation policy does not reserve swap space when processes allocate memory allocations. This could lead to swap space overcommitment which forces AIX to kill processes when it runs out of swap space. Either:
  • Ensure sufficient swap space or
  • Set the environment variables:
    PSALLOC=EARLY
    NODISCLAIM=TRUE
AIX/Oracle Recommendations
asynchronous I/O parameters Asynchronous I/O NA C The default asynchronous I/O parameters are set too low.
WebLogic / AIX Recommendations
udp_sendspace Asynchronous I/O C C WebLogic's multicast packets are larger than the AIX udp_sendspace buffers. At the default level, you may get multicast errors.

Set udp_sendspace to 32768
