在linux 上安装oracle10个时设定limit的问题

lory

oracle 10g database在linux安装时，设定oracle用户limit时：为何在pam模组里面添加了limit限制然后又要在login shell里面修改呢，这样相互的设定会被影响。经过测试login shell的设定会覆盖pam模组的设定
那为何操作手册还要设定两次limit呢

以下是oracle 10g 的linux安装手册原文

1. To increase the shell limits:
   
2. 1. Add the following lines to the /etc/security/limits.conf file:
   
3. oracle soft nproc 2047
   
4. oracle hard nproc 16384
   
5. oracle soft nofile 1024
   
6. oracle hard nofile 65536
   
7. 2. Add or edit the following line in the /etc/pam.d/login file, if it does not
   
8. already exist:
   
9. session required /lib/security/pam_limits.so
   
10. session required pam_limits.so
    
11. 3. Depending on the oracle user's default shell, make the following changes to the
    
12. default shell start-up file:
    
13. ■ For the Bourne, Bash, or Korn shell, add the following lines to the
    
14. /etc/profile file (or the file on SUSE systems)/etc/profile.local:
    
15. if [ $USER = "oracle" ]; then
    
16. if [ $SHELL = "/bin/ksh" ]; then
    
17. ulimit -p 16384
    
18. ulimit -n 65536
    
19. else
    
20. ulimit -u 16384 -n 65536
    
21. fi

安装的初始化参数设置很关键，前面没花时间把关好，后面出问题来处理更耗时。
