opatch被异常中断后的处理
今天在打一个patch的时候，已经是用opatch执行到了最后一个patch，一时手欠，没看清楚telnet的窗口，不小心按下了ctrl+C，于是，opatch被中断了。汗了，晚节不保啊！ 再次执行opatch apply，报错：

HPUX中常用的getconf命令参数
常用的getconf命令参数，在此记录，补充一下自己的os知识：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
getconf MACHINE_SERIAL 获取主机设备序列号，这个序列号可用于HP的800报障。 getconf PAGE_SIZE 每个内存页的大小。用kmeminfo或者ps -lfp 看内存显示的结果是多少个内存页，要乘以这个每个内存页的大小才得到每个进程的占用内存。 getconf KERNEL_BITS 查看操作系统是32位还是64位，在安装oracle前必须弄清楚os版本，安装对应版本的oracle。 getconf MACHINE_MODEL 查看主机的具体型号。如rp8440，N4000-55 getconf HW_CPU_SUPP_BITS 硬件cpu支持多少位。如64位的cpu支持64位的os和32位的os。 |
