Oracle 11G for redhat 自启动脚本

阅读更多关于 Oracle 11G for redhat 自启动脚本

在$ORACLE_HOME/bin中，有dbstart和dbshut这两个脚本，可以使用这两个oracle自带的脚本实现oracle的开机自启动。这个脚本中包含oraclelistener、instance、asm instances的启动，同样dbshut也是起到关闭服务的作用。方法一：使用/etc/rc.local系统开机启动脚本，启动oracle 配置系统使dbstart和dbshut脚本起作用： 1）、以root编辑/etc/oratab， orcl:/home/oracle/app/oracle/product/11.2.0/dbhome_1:N 这种格式， orcl是你的ORACLE_SID， /home/oracle/app/oracle/product/11.2.0/dbhome_1是ORACLE_HOME，这里需要把N改为Y，即orcl:/home/oracle/app/oracle/product/11.2.0/dbhome_1: Y 。 2）、以oracle编辑$ORACLE_HOME/bin/dbstart，找到其中第78行:ORACLE_HOME_LISTNER=改为你自己的路径，或者可以改成ORACLE_HOME_LISTNER=$ORACLE_HOME 保存脚本，以oracle用户运行dbshut和dbstart看是否能关闭、启动数据库。如果不能

问题 I want to unzip a zipped folder on my Redhat machine. To do this I send a bash script the string; "unzip /usr/bin/Folder.gz" This unzips the folder no problem, as in I get the general inflating folderA/folderB/fileX etc. However, I want to hold the code at the unzip command, waiting until the unzipping is complete. I have tried using sleep(5) but I don’t want to use this and just hope that it will always take less than five seconds especially this is would be inefficient for very small zipped

阅读更多关于 measure CPU usage per second of a dynamically linked library

问题 I have a sample application which uses a dynamically linked library library.so . I was measuring CPU usage of the sample application with the top command.
