Issue
Resolution
- Open file descriptors, soft nofile at least 16384, hard nofile at least 65536.
- Number of processes available to a single user, soft nproc at least 2047, hard nproc at least 16384.
- Size of the stack segment of the process stack, soft stack at least 10240, hard stack at least 32768.
- Check the soft and hard limits for the open file descriptor setting for user oracle. Ensure that the result is in the recommended range. For example:
$ ulimit -Sn 16384 $ ulimit -Hn 65536
- Check the soft and hard limits for the number of processes available to user oracle. Ensure that the result is in the recommended range. For example:
$ ulimit -Su 16384 $ ulimit -Hu 16384
- Check the soft and hard limits for the stack setting for user oracle. Ensure that the result is in the recommended range. For example:
$ ulimit -Ss 10240 $ ulimit -Hs 32768
To modify these settings, log in as user root and
- Edit /etc/security/limits.conf
cd /etc/security vi limits.conf
- Add these lines to the bottom of the file. These entries need to be defined for the oracle user.
oracle soft nofile 16384 oracle hard nofile 65536 oracle soft nproc 16384 oracle hard nproc 16384 oracle soft stack 10240 oracle hard stack 32768
The new values will take effect immediately. No application or system restart is required.
