To implement the solution, please execute the following steps:

Tune the application running on the 32-bit environment so that it will not consume greater than
2.7GB of virtual memory when the '/3GB' switch is set in the 'boot.ini' file.
In the case of Oracle encountering the OS resource issue, the options are:

1) Reduce the amount of SGA needed to be allocated for the database.
2) Limit the number of dedicated connections to the database and the amount of memory each user
process will consume.
3) Change from dedicated connections to multi-threaded server (MTS) connections as MTS only
uses a fraction of the amount of memory allocated to each user process when initial connection to
the database is established.

我觉得重点是OS error 信息，比如errpt /errpt -aj xxx ,soft/hard limit，space情况等

可以看到上面的启动过程中刨除了包含的这个错误

对于这个问题是操作系统的参数设置错误，为这个测试是在linux+10gr5下进行测试的，这个错误是在启动阶段发生的，有别于楼主的在运行过程中发现的，但是我想问题的根本原因应该是没有区别的，应该在os层面找找原因。

下面继续看测试，检查了下OS的参数设置：
  1. [root@gtlions ~]# /sbin/sysctl -p
  2. net.ipv4.ip_forward = 0
  3. net.ipv4.conf.default.rp_filter = 2
  4. net.ipv4.conf.default.accept_source_route = 0
  5. kernel.sysrq = 0
  6. kernel.core_uses_pid = 1
  7. net.ipv4.tcp_syncookies = 1
  8. kernel.msgmnb = 65536
  9. kernel.msgmax = 65536
  10. kernel.shmmax = 4294967295
  11. kernel.shmall = 268435456
  12. fs.aio-max-nr = 1048576
  13. fs.file-max = 6815744
  14. net.ipv4.ip_local_port_range = 9000 65500
  15. net.core.rmem_default = 262144
  16. net.core.rmem_max = 4194304
  17. net.core.wmem_default = 262144
  18. net.core.wmem_max = 1048586
  19. kernel.sem = 250  100
复制代码

注意上面的最后一个参数kernel.sem = 250  100这个不正常的值，现在把这个参数该成正常值。

  20. kernel.sem = 250 32000 100 128

现在来看下是否可以正常启动数据库了。
