重启系统资源生效To check resource limits:

1. Log in as an installation owner.

2. Check the soft and hard limits for the file descriptor setting. Ensure that the result is in the recommended range. For example:

   $ ulimit -Sn
   4096
   $ ulimit -Hn
   65536
   

3. Check the soft and hard limits for the number of processes available to a user. Ensure that the result is in the recommended range. For example:

   $ ulimit -Su
   2047
   $ ulimit -Hu
   16384
   

4. Check the soft limit for the stack setting. Ensure that the result is in the recommended range. For example:

   $ ulimit -Ss
   10240
   $ ulimit -Hs
   32768
   

5. Repeat this procedure for each Oracle software installation owner.
