Computer node implementation checklist
You can review the computer node implementation checklist for specific 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:
|
| 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 |
