如何查看AIX是在32位模式下还是64位模式下 使用那个命令？\r\n小弟是刚学AIX 请高手指教！！

花好月不圆

这是我看到对AIX 64位问题表述最简单明了的帖子：\r\nThe types of 64-bit processors are as follows: \r\n\r\nPowerPC_RS64 \r\nPowerPC_RS64 II \r\nPowerPC_RS64 III \r\nPowerPC_Power3 \r\nPowerPC_Power3 II \r\n\r\nThis is directly from IBM:\r\n\r\nCOMMAND: bootinfo -K\r\n\r\nReports whether the system is running a 32-bit or\r\n64-bit KERNEL.\r\n\r\n- AIX4.3 has only a 32-bit kernel\r\n\r\n- AIX5.1 has both 32-bit and 64-bit kernels. Only\r\none [1] can be active on a system [or within a\r\nLPAR] at a time.\r\n\r\nCOMMAND: bootinfo -y:\r\n\r\nReports whether the CPU is 32-bit or 64-bit.\r\n\r\nCOMMAND: oslevel\r\n\r\nReports the AIX version.\r\n\r\nCOMMAND: smit load64bit\r\n\r\nUsed to determine/set the USER-SPACE runtime\r\nenvironment is 32-bit or 64-bit\r\n\r\nCOMPATIBILITY OPTIONS:\r\n\r\nAppl System\r\nUser Kernel\r\nMode Mode Hrdw Compatibility\r\n------ ------ ------ --------------\r\nOption 1: 32-bit 32-bit 32-bit No limitations\r\n\r\nOption 2: 32-bit 32-bit 64-bit Note #1\r\n\r\nOption 3: 32-bit 64-bit 32-bit Note #2\r\n\r\nOption 4: 32-bit 64-bit 64-bit Note #2\r\nNote #5\r\nNote #7\r\n\r\nOption 5: 64-bit 32-bit 32-bit Note #2\r\n\r\nOption 6: 64-bit 32-bit 64-bit Note #1\r\nNote #4\r\nNote #7\r\n\r\nOption 7: 64-bit 64-bit 32-bit Note #2\r\n\r\nOption 8: 64-bit 64-bit 64-bit Note #3\r\nNote #4\r\nNote #5\r\n\r\nNote 1: Requires AIX4.3 or later.\r\n\r\nNote 2: Invalid - not possible to run 64-bit\r\nkernel on 32-bit hardware.\r\n\r\nNote 3: Requires AIX5.1 or later.\r\n\r\nNote 4: 64-bit user-space appls:\r\n\r\nbos.64bit fileset must be installed and\r\nactivated using the command \"smit load64bit\"\r\n\r\nAIX4.3 64-bit appls not supported on AIX5.1.\r\nThey must be recompiled.\r\n\r\nNote 5: The AIX5.1 32-bit kernel is default.\r\n\r\nThe AIX5.1 64-bit kernel is optional.\r\n\r\nThe AIX5.1 64-bit kernel is installed on\r\n64-bit hrdw by default, but is inactive.\r\n\r\nThe AIX5.1 64-bit kernel can be activated at\r\ninstall-time or later using \"smit load64bit\"\r\n\r\nUse \"bootinfo -K\" to determine which kernel\r\nis running.\r\n\r\nUse \"lslpp -h bos.mp64\" to determine if the\r\n64-bit kernel is installed.

You can use following commands with option to check kernel  and  hardware bitmode , all commands tested on AIX 5.2.\r\n\r\ngetconf KERNEL_BITMODE        (check kernel is 32bit or 64bit)\r\nbootinfo -K                        (check kernel is 32bit or 64bit)\r\ngetconf HARDWARE_BITMODE        (check hardware bitmode is 32 or 64bit)\r\nbootinfo -y                        (check hardware bitmode is 32 or 64bit)\r\nprtconf -c                        (check hardware bitmode is 32 or 64bit)

bootinfo -k我运行得到的结果是3\r\nprtconf可以得到清楚的描述。
