今天启动oracle监听发现报：
TNSLSNR for Linux: Version 10.2.0.4.0 - Production
System parameter file is /u01/app/oracle/network/admin/listener.ora
Log messages written to /u01/app/oracle/network/log/listener.log
Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))
TNS-12555: TNS:permission denied

TNS-00525: Insufficient privilege for operation
Linux Error: 1: Operation not permitted
以前都是OK的，于是跟踪启动执行过程：
