How Can I View and Change the Number of Operating System Handles

Question

How can I view and change the number of operating system handles?

Answer

Ensure that the number of operating system handles is greater than or equal to 65535 when the eSight is running properly. If the user provides the operating system, perform the following steps to check and change the number of operating system handles:
NOTE:

If the eSight is deployed in a two-node cluster mode, the number of operating system handles on the active and standby servers must be the same.

  1. Log in to the eSight server as the ossuser user.
  2. Run the following command to switch to the root user.

    > su - root

  3. Run the following command to check the current number of handles:

    # ulimit -n

    If the number of handles is less than 65535, go to 4.

  4. Run the following command to change the number of operating system handles:

    # sed -i '/^[^#].*[[:space:]]\+nofile[[:space:]]\+/d' /etc/security/limits.conf

    # sed -i '$a\* - nofile 65535' /etc/security/limits.conf

  5. Restart the operating system.

    # reboot
